Certain balances at December 31, 2015 have been reclassified within our Consolidated Balance Sheet (“Balance Sheet”) to conform to our December 31, 2016 presentation. On February 27, 2017, we entered into a definitive agreement (the “CS Agreement”) with CSVC Acquisition Corp (“CSVC”), under which CSVC agreed to acquire our “Capital Services Operations” (primarily comprised of our former Capital Services reportable segment). Our Capital Services Operations provided comprehensive and integrated maintenance services, environmental engineering and remediation, construction services, program management, and disaster response and recovery services for private-sector customers and governments. We completed the sale of the Capital Services Operations on June 30, 2017 (the “Closing Date”), as described in Note 5 . We considered the Capital Services Operations to be a discontinued operation in the first quarter 2017, as the divestiture represented a strategic shift and would have a material effect on our operations and financial results. In the July 2017, we initiated a plan to market and sell our “Technology Operations” (primarily comprised of our former Technology reportable segment and our “Engineered Products Operations”, representing a portion of our Fabrication Services reportable segment). Our Technology Operations provides proprietary process technology licenses and associated engineering services, catalysts and engineered products, primarily for the petrochemical and refining industries, and offers process planning and project development services and a comprehensive program of aftermarket support. We considered the Technology Operations to be a discontinued operation in the third quarter 2017, as the anticipated divestiture represented a strategic shift and would have a material effect on our operations and financial results. Financial information and disclosures for all periods presented have been recast on a retrospective basis as if the discontinued operations criteria for the Capital Services Operations and Technology Operations were met as of December 31, 2016. Operating results of the Capital Services Operations and Technology Operations have been classified as a discontinued operation within the Consolidated Statements of Operations (the “Statement of Operations”) for 2016, 2015 and 2014. Further, the assets and liabilities of the Capital Services Operations and Technology Operations have been classified as assets and liabilities of discontinued operations within our December 31, 2016 and 2015 Balance Sheets. Cash flows of the Capital Services Operations and Technology Operations are not reported separately within our Consolidated Statements of Cash Flows. Unless otherwise noted, the values presented throughout the notes to our Financial Statements relate to our continuing operations. See Note 5 for additional discussion of our discontinued operations. Use of Estimates —The preparation of our Financial Statements in conformity with U.S. GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses and related disclosures of contingent assets and liabilities. We believe the most significant estimates and judgments are associated with revenue recognition for our contracts, including estimating costs and the recognition of incentive fees and unapproved change orders and claims; fair value and recoverability assessments that must be periodically performed with respect to long-lived tangible assets, goodwill and other intangible assets; valuation of deferred tax assets and financial instruments; the determination of liabilities related to self-insurance programs and income taxes; and consolidation determinations with respect to our partnering arrangements. If the underlying estimates and assumptions upon which our Financial Statements are based change in the future, actual amounts may differ from those included in the accompanying Financial Statements. Revenue Recognition —Our revenue is primarily derived from long-term contracts and is generally recognized using the percentage of completion (“POC”) method, primarily based on the percentage that actual costs-to-date bear to total estimated costs to complete each contract. We follow the guidance of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Revenue Recognition Topic 605-35 for accounting policies relating to our use of the POC method, estimating costs, and revenue recognition, including the recognition of incentive fees, unapproved change orders and claims, and combining and segmenting contracts. We primarily utilize the cost-to-cost approach to estimate POC as we believe this method is less subjective than relying on assessments of physical progress. Under the cost-to-cost approach, the use of estimated costs to complete each contract is a significant variable in the process of determining recognized revenue and is a significant factor in the accounting for contracts. Significant estimates that impact the cost to complete each contract are costs of engineering, materials, components, equipment, labor and subcontracts; labor productivity; schedule durations, including subcontractor or supplier progress; liquidated damages; contract disputes, including claims; achievement of contractual performance requirements; and contingency, among others. The cumulative impact of revisions in total cost estimates during the progress of work is reflected in the period in which these changes become known, including, to the extent required, the reversal of profit recognized in prior periods and the recognition of losses expected to be incurred on contracts in progress. Due to the various estimates inherent in our contract accounting, actual results could differ from those estimates. See Note 17 for discussion of projects with significant changes in estimated margins during 2016, 2015 and 2014. Our long-term contracts are awarded on a competitively bid and negotiated basis and the timing of revenue recognition may be impacted by the terms of such contracts. We use a range of contracting options, including cost-reimbursable, fixed-price and hybrid, which has both cost-reimbursable and fixed-price characteristics. Fixed-price contracts, and hybrid contracts with a more significant fixed-price component, tend to provide us with greater control over project schedule and the timing of when work is performed and costs are incurred, and accordingly, when revenue is recognized. Cost-reimbursable contracts, and hybrid contracts with a more significant cost-reimbursable component, generally provide our customers with greater influence over the timing of when we perform our work, and accordingly, such contracts often result in less predictability with respect to the timing of revenue recognition. Contract revenue for our long-term contracts recognized under the POC method reflects the original contract price adjusted for approved change orders and estimated recoveries for incentive fees, unapproved change orders and claims. We recognize revenue associated with incentive fees when the value can be reliably estimated and recovery is probable. We recognize revenue associated with unapproved change orders and claims to the extent the related costs have been incurred, the value can be reliably estimated and recovery is probable. Our recorded incentive fees, unapproved change orders and claims reflect our best estimates of recovery amounts; however, the ultimate resolution and amounts received could differ from these estimates. See Note 17 for additional discussion of our recorded unapproved change orders, claims and incentives. With respect to our engineering, procurement, and construction (“EPC”) services, our contracts are not segmented between types of services, such as engineering and construction, if each of the EPC components is negotiated concurrently or if the pricing of any such services is subject to the ultimate negotiation and agreement of the entire EPC contract. However, an EPC contract including technology or fabrication services may be segmented if we satisfy the segmenting criteria in ASC 605-35. Revenue recorded in these situations is based on our prices and terms for similar services to third party customers. Segmenting a contract may result in different interim rates of profitability for each scope of service than if we had recognized revenue without segmenting. In some instances, we may combine contracts that are entered into in multiple phases, but are interdependent and include pricing considerations by us and the customer that are impacted by all phases of the project. Otherwise, if each phase is independent of the other and pricing considerations do not give effect to another phase, the contracts will not be combined. Cost of revenue for our long-term contracts includes direct contract costs, such as materials and labor, and indirect costs that are attributable to contract activity. The timing of when we bill our customers is generally dependent upon advance billing terms, milestone billings based on the completion of certain phases of the work, or when services are provided. Projects with costs and estimated earnings recognized to date in excess of cumulative billings are reported on the Balance Sheets as costs and estimated earnings in excess of billings. Projects with cumulative billings in excess of costs and estimated earnings recognized to date are reported on the Balance Sheets as billings in excess of costs and estimated earnings. The net balances on our Balance Sheets are collectively referred to as Contracts in Progress, net and the components of these balances at December 31, 2016 and 2015 were as follows: December 31, 2016 December 31, 2015 Asset Liability Asset Liability Costs and estimated earnings on contracts in progress $ 7,852,740 $ 22,544,241 $ 10,445,182 $ 17,779,376 Billings on contracts in progress (7,522,308 ) (23,763,065 ) (10,014,140 ) (19,368,704 ) Contracts in Progress, net $ 330,432 $ (1,218,824 ) $ 431,042 $ (1,589,328 ) Any uncollected billed amounts, including contract retentions, are reported as accounts receivable. At December 31, 2016 and 2015 , accounts receivable included contract retentions of approximately $72,100 and $55,400 , respectively. Contract retentions due beyond one year were approximately $37,500 at December 31, 2016 . Revenue for our service contracts that do not satisfy the criteria for revenue recognition under the POC method is recorded at the time services are performed. Revenue associated with incentive fees for these contracts is recognized when earned. Unbilled receivables for our service contracts are recorded within accounts receivable and were not material at December 31, 2016 and 2015 . Revenue for our pipe and steel fabrication and catalyst manufacturing contracts that are independent of an EPC contract, or for which we satisfy the segmentation criteria discussed above, is recognized upon shipment of the fabricated or manufactured units. During the fabrication or manufacturing process, all related direct and allocable indirect costs are capitalized as work in process inventory and such costs are recorded as cost of revenue at the time of shipment. Our billed and unbilled revenue may be exposed to potential credit risk if our customers should encounter financial difficulties, and we maintain reserves for specifically-identified potential uncollectible receivables. At December 31, 2016 and 2015 , our allowances for doubtful accounts were not material. Precontract Costs —Precontract costs are generally charged to cost of revenue as incurred, but, in certain cases their recognition may be deferred if specific probability criteria are met. We had no significant deferred precontract costs at December 31, 2016 or 2015 . Research and Development —Expenditures for research and development activities are charged to cost of revenue as incurred and were $4,699 , $4,607 and $3,629 for 2016 , 2015 and 2014 , respectively. Other Operating Expense (Income), Net — Other operating expense (income), net , generally represents (gains) losses associated with the sale or disposition of property and equipment. For 2015, other operating expense (income), net also included a foreign exchange loss of approximately $11,000 associated with the re-measurement of certain non-U.S. Dollar denominated net assets. Integration Related Costs —Integration related costs were $26,356 for 2014, and primarily related to facility consolidations, including the associated accrued future lease costs for vacated facilities and unutilized capacity, personnel relocation and severance related costs, and systems integration costs. Depreciation Expense —Property and equipment are recorded at cost and depreciated on a straight-line basis over their estimated useful lives, including buildings and improvements ( 10 to 40 years) and plant and field equipment ( 1 to 15 years). Renewals and betterments that substantially extend the useful life of an asset are capitalized and depreciated. Leasehold improvements are depreciated over the lesser of the useful life of the asset or the applicable lease term. Depreciation expense is primarily included within cost of revenue and was $63,830 , $84,939 and $96,209 for 2016 , 2015 and 2014 , respectively. See Note 9 for disclosure of the components of property and equipment. Recoverability of Goodwill —Goodwill is not amortized to earnings, but instead is reviewed for impairment at least annually at a reporting unit level, absent any indicators of impairment or when other actions require an impairment assessment (such as a change in reporting units). We perform our annual impairment assessment during the fourth quarter of each year based upon balances as of October 1. We identify a potential impairment by comparing the fair value of the applicable reporting unit to its net book value, including goodwill. If the net book value exceeds the fair value of the reporting unit, an indication of potential impairment exists, and we measure the impairment by comparing the carrying value of the reporting unit’s goodwill to its implied fair value. To determine the fair value of our reporting units and test for impairment, we utilize an income approach (discounted cash flow method) as we believe this is the most direct approach to incorporate the specific economic attributes and risk profiles of our reporting units into our valuation model. This is consistent with the methodology used to determine the fair value of our reporting units in previous years. We generally do not utilize a market approach given the lack of relevant information generated by market transactions involving comparable businesses. However, to the extent market indicators of fair value become available, we consider such market indicators in our discounted cash flow analysis and determination of fair value. See Note 7 for additional discussion of our goodwill and related goodwill impairment recorded during 2016. Recoverability of Other Long-Lived Assets —We amortize our finite-lived intangible assets on a straight-line basis with lives ranging from 6 to 20 years, absent any indicators of impairment. We review tangible assets and finite-lived intangible assets for impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable. If a recoverability assessment is required, the estimated future cash flow associated with the asset or asset group will be compared to the asset’s carrying amount to determine if an impairment exists. See Note 7 for additional discussion of our intangible assets. Earnings Per Share (“EPS”)— Basic EPS is calculated by dividing net income attributable to CB&I by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the assumed conversion of dilutive securities, consisting of restricted shares, performance based shares (where performance criteria have been met), stock options and directors’ deferred-fee shares. See Note 3 for calculations associated with basic and diluted EPS. Cash Equivalents —Cash equivalents are considered to be highly liquid securities with original maturities of three months or less. Inventory —Inventory is recorded at the lower of cost or market and cost is determined using the first-in-first-out or weighted-average cost method. The cost of inventory includes acquisition costs, production or conversion costs, and other costs incurred to bring the inventory to a current location and condition. An allowance for excess or inactive inventory is recorded based upon an analysis that considers current inventory levels, historical usage patterns, estimates of future sales expectations and salvage value. See Note 6 for additional discussion of our inventory. Foreign Currency —The nature of our business activities involves the management of various financial and market risks, including those related to changes in foreign currency exchange rates. The effects of translating financial statements of foreign operations into our reporting currency are recognized as a cumulative translation adjustment in accumulated other comprehensive income (loss) (“AOCI”) which is net of tax, where applicable. With the exception of a foreign exchange loss of approximately $11,000 included within other operating expense (income), net related to the re-measurement of certain non-U.S. Dollar denominated net assets during 2015, foreign currency transactional and re-measurement exchange gains (losses) are included within cost of revenue and were not material in 2016 , 2015 and 2014 . Financial Instruments —We utilize derivative instruments in certain circumstances to mitigate the effects of changes in foreign currency exchange rates and interest rates, as described below: • Foreign Currency Exchange Rate Derivatives —We do not engage in currency speculation; however, we utilize foreign currency exchange rate derivatives on an ongoing basis to hedge against certain foreign currency related operating exposures. We generally seek hedge accounting treatment for contracts used to hedge operating exposures and designate them as cash flow hedges. Therefore, gains and losses, exclusive of credit risk and forward points (which represent the time value component of the fair value of our derivative positions), are included in AOCI until the associated underlying operating exposure impacts our earnings. Changes in the fair value of (1) credit risk and forward points, (2) instruments deemed ineffective during the period, and (3) instruments that we do not designate as cash flow hedges are recognized within cost of revenue. • Interest Rate Derivatives —At December 31, 2016 , we continued to utilize a swap arrangement to hedge against interest rate variability associated with $290,375 of our outstanding $300,000 unsecured term loan (the “Term Loan”). The swap arrangement has been designated as a cash flow hedge as its critical terms matched those of the Term Loan at inception and through December 31, 2016 . Accordingly, changes in the fair value of the swap arrangement are included in AOCI until the associated underlying exposure impacts our earnings. For those contracts designated as cash flow hedges, we document all relationships between the derivative instruments and associated hedged items, as well as our risk-management objectives and strategy for undertaking hedge transactions. This process includes linking all derivatives to specific firm commitments or highly-probable forecasted transactions. We continually assess, at inception and on an ongoing basis, the effectiveness of derivative instruments in offsetting changes in the cash flow of the designated hedged items. Hedge accounting designation is discontinued when (1) it is determined that the derivative is no longer highly effective in offsetting changes in the cash flow of the hedged item, including firm commitments or forecasted transactions, (2) the derivative is sold, terminated, exercised, or expires, (3) it is no longer probable that the forecasted transaction will occur, or (4) we determine that designating the derivative as a hedging instrument is no longer appropriate. See Note 11 for additional discussion of our financial instruments. Income Taxes —Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis using currently enacted income tax rates for the years in which the differences are expected to reverse. A valuation allowance is provided to offset any net deferred tax assets (“DTA(s)”) if, based upon the available evidence, it is more likely than not that some or all of the DTAs will not be realized. The realization of our net DTAs depends upon our ability to generate sufficient future taxable income of the appropriate character and in the appropriate jurisdictions. Income tax and associated interest and penalty reserves, where applicable, are recorded in those instances where we consider it more likely than not that additional tax will be due in excess of amounts reflected in income tax returns filed worldwide, irrespective of whether or not we have received tax assessments. We continually review our exposure to additional income tax obligations and, as further information is known or events occur, changes in our tax and interest reserves may be recorded within income tax expense and interest expense, respectively. See Note 16 for additional discussion of our income taxes. Partnering Arrangements — In the ordinary course of business, we execute specific projects and conduct certain operations through joint venture, consortium and other collaborative arrangements (collectively referred to as “venture(s)”). We have various ownership interests in these ventures, with such ownership typically proportionate to our decision making and distribution rights. The ventures generally contract directly with the third party customer; however, services may be performed directly by the ventures, or may be performed by us, our partners, or a combination thereof. Venture net assets consist primarily of working capital and property and equipment, and assets may be restricted from being used to fund obligations outside of the venture. These ventures typically have limited third party debt or have debt that is non-recourse in nature; however, they may provide for capital calls to fund operations or require participants in the venture to provide additional financial support, including advance payment or retention letters of credit. Each venture is assessed at inception and on an ongoing basis as to whether it qualifies as a VIE under the consolidations guidance in ASC 810. A venture generally qualifies as a VIE when it (1) meets the definition of a legal entity, (2) absorbs the operational risk of the projects being executed, creating a variable interest, and (3) lacks sufficient capital investment from the partners, potentially resulting in the venture requiring additional subordinated financial support, if necessary, to finance its future activities. If at any time a venture qualifies as a VIE, we perform a qualitative assessment to determine whether we are the primary beneficiary of the VIE and, therefore, need to consolidate the VIE. We are the primary beneficiary if we have (1) the power to direct the economically significant activities of the VIE and (2) the right to receive benefits from, and obligation to absorb losses of, the VIE. If the venture is a VIE and we are the primary beneficiary, or we otherwise have the ability to control the venture, we consolidate the venture. If we are not determined to be the primary beneficiary of the VIE, or only have the ability to significantly influence, rather than control the venture, we do not consolidate the venture. We account for unconsolidated ventures using either proportionate consolidation for both the Balance Sheet and Statement of Operations, when we meet the applicable accounting criteria to do so, or the equity method. See Note 8 for additional discussion of our material partnering arrangements. New Accounting Standards —In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, which provides a single comprehensive accounting standard for revenue recognition for contracts with customers and supersedes current industry-specific guidance, including ASC 605-35. The new standard prescribes a five-step revenue recognition model that focuses on transfer of control and entitlement to payment when determining the amount of revenue to be recognized. The new model requires companies to identify contractual performance obligations and determine whether revenue should be recognized at a point in time or over time for each of these obligations. These concepts, as well as other aspects of the ASU, may change the method and/or timing of revenue recognition for certain of our contracts, primarily associated with our fabrication and manufacturing contracts. We expect that revenue generated from our EPC and engineering services contracts will continue to be recognized over time utilizing the cost-to-cost measure of progress consistent with current practice. We also expect our revenue recognition disclosures to significantly expand due to the new qualitative and quantitative requirements regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from our contracts. We will adopt the standard, including any updates to the standard, upon its effective date in the first quarter 2018 utilizing the modified retrospective approach. This approach will result in a cumulative adjustment to beginning equity in the first quarter 2018 for contracts impacted by the adoption of the standard. We are continuing to assess the potential impact of the new standard on our Financial Statements. In February 2016, the FASB issued ASU 2016-02, which requires the recognition of a right-of-use asset and a lease liability for most lease arrangements with a term greater than one year, and increases qualitative and quantitative disclosures regarding leasing transactions. The standard is effective for us in the first quarter 2019, although early adoption is permitted. Transition requires application of the new guidance at the beginning of the earliest comparative balance sheet period presented utilizing a modified retrospective approach. We are assessing the timing of adoption of the new standard and its potential impact on our Financial Statements. In March 2016, the FASB issued ASU 2016-09, which modifies the accounting for excess tax benefits and tax deficiencies associated with share-based payments, and amends the associated cash flow presentation. ASU 2016-09 eliminates the requirement to recognize excess tax benefits in additional paid-in capital (“APIC”), and the requirement to evaluate tax deficiencies for APIC or income tax expense classification, and provides for these benefits or deficiencies to be recorded as an income tax expense or benefit in the income statement. Additionally, tax benefits of dividends on share-based payment awards will also be reflected as an income tax expense or benefit in the income statement. With these changes, tax-related cash flows resulting from share-based payments will be classified as operating activities as opposed to financing, as currently presented. We will adopt the standard upon its effective date in the first quarter 2017 and do not believe it will have a material impact on our Financial Statements. In the first quarter 2016, we adopted ASU 2015-02, which amends existing consolidation requirements in ASC 810 associated with: (1) determining the consolidation model and assessing control for limited partnerships and similar entities; (2) determining when fees paid to decision makers or service providers are variable interests; and (3) evaluating interests held by de facto agents or related parties of the reporting entity. Our adoption did not have a material impact on our Financial Statements. In the first quarter 2016, we adopted ASU 2015-03, which requires presentation of debt issuance costs as a direct deduction from the related debt liability rather than as an asset, as presented under previous guidance. Our adoption resulted in the reclassification of deferred debt issuance costs from other current assets and other non-current assets of approximately $2,129 and $8,168 , respectively, to current maturities of long-term debt and long-term debt, respectively, in our December 31, 2015 Balance Sheet.

Antidilutive shares excluded from diluted EPS were not material for 2016 and 2014 .

DISPOSITION OF NUCLEAR OPERATIO

DISPOSITION OF NUCLEAR OPERATIONS	12 Months Ended
	Dec. 31, 2016
Discontinued Operations and Disposal Groups [Abstract]
DISPOSITION OF NUCLEAR OPERATIONS	DISPOSITION OF NUCLEAR OPERATIONS On December 31, 2015 we completed the sale of our nuclear power construction business (our “Nuclear Operations”), previously included within our Engineering & Construction operating group, to Westinghouse Electric Company LLC (“WEC”) for transaction consideration of approximately $161,000 , which is due upon WEC’s substantial completion of the acquired VC Summer and Vogtle nuclear projects. At December 31, 2015, we recorded the present value of the transaction consideration (the “Transaction Receivable”); however, during the fourth quarter 2016 we determined that recovery was no longer probable and recorded a non-cash pre-tax charge of approximately $148,100 (approximately $96,300 after-tax) to reserve the Transaction Receivable. The charge is included in “Loss on Net Assets Sold and Intangible Assets Impairment” in our Statement of Operations. See Note 13 for discussion of a dispute with WEC relating to the sale of our Nuclear Operations. As a result of the sale of our Nuclear Operations in 2015, we recorded a non-cash pre-tax charge related to the impairment of goodwill and intangible assets and a loss on net assets sold. A summary of the charge is as follows: Year Ended December 31, 2015 Loss on net assets sold $ 973,651 Intangible assets impairment 79,100 Loss on net assets sold and intangible assets impairment 1,052,751 Goodwill impairment 453,100 Total pre-tax charge $ 1,505,851 The net tax benefit of the charge was approximately $370,700 , reflecting the non-deductibility of the goodwill impairment, and resulted in an after-tax charge of approximately $1,135,200 . The impact of the loss on net assets sold and intangible assets impairment is included in “Loss on net assets sold and intangible assets impairment” in our Statement of Operations, and the impact of the goodwill impairment is included in “Goodwill impairment” in our Statement of Operations. The revenue and pre-tax income of our former Nuclear Operations for 2015 and 2014 was as follows: Years Ended December 31, 2015 2014 Revenue $ 2,061,167 $ 1,841,018 Pre-tax income $ 215,150 $ 151,800 DISCONTINUED OPERATIONS Capital Services Operations Transaction Summary —As discussed in Note 2 , on June 30, 2017 we completed the sale of our Capital Services Operations as provided for by the CS Agreement entered into on February 27, 2017. Under the CS Agreement, including its amendment prior to the Closing Date, the purchase price was $700,000 , subject to certain adjustments including a working capital adjustment, whereby the purchase price would be adjusted to the extent actual working capital of the Capital Services Operations on the Closing Date differed from required working capital under the CS Agreement. After giving effect to working capital and other adjustments estimated prior to the Closing Date of approximately $32,600 , we received cash proceeds of approximately $667,400 (approximately $645,500 net of cash sold) on the Closing Date. Based on actual working capital of the Capital Services Operations on the Closing Date, we estimate net final proceeds of approximately $599,000 , including approximately $46,500 for transaction costs and the aforementioned post-closing working capital adjustment. As a result of the aforementioned, during 2017, we recorded a pre-tax charge of approximately $64,800 , and income tax expense of approximately $55,800 resulting from a taxable gain on the transaction (due primarily to the non-deductibility of goodwill). The transaction did not result in any material cash taxes associated with the taxable gain due to the use of previously recorded net operating loss carryforwards.

Discontinued Operations and Disposal Groups [Abstract]
DISCONTINUED OPERATIONS	DISPOSITION OF NUCLEAR OPERATIONS On December 31, 2015 we completed the sale of our nuclear power construction business (our “Nuclear Operations”), previously included within our Engineering & Construction operating group, to Westinghouse Electric Company LLC (“WEC”) for transaction consideration of approximately $161,000 , which is due upon WEC’s substantial completion of the acquired VC Summer and Vogtle nuclear projects. At December 31, 2015, we recorded the present value of the transaction consideration (the “Transaction Receivable”); however, during the fourth quarter 2016 we determined that recovery was no longer probable and recorded a non-cash pre-tax charge of approximately $148,100 (approximately $96,300 after-tax) to reserve the Transaction Receivable. The charge is included in “Loss on Net Assets Sold and Intangible Assets Impairment” in our Statement of Operations. See Note 13 for discussion of a dispute with WEC relating to the sale of our Nuclear Operations. As a result of the sale of our Nuclear Operations in 2015, we recorded a non-cash pre-tax charge related to the impairment of goodwill and intangible assets and a loss on net assets sold. A summary of the charge is as follows: Year Ended December 31, 2015 Loss on net assets sold $ 973,651 Intangible assets impairment 79,100 Loss on net assets sold and intangible assets impairment 1,052,751 Goodwill impairment 453,100 Total pre-tax charge $ 1,505,851 The net tax benefit of the charge was approximately $370,700 , reflecting the non-deductibility of the goodwill impairment, and resulted in an after-tax charge of approximately $1,135,200 . The impact of the loss on net assets sold and intangible assets impairment is included in “Loss on net assets sold and intangible assets impairment” in our Statement of Operations, and the impact of the goodwill impairment is included in “Goodwill impairment” in our Statement of Operations. The revenue and pre-tax income of our former Nuclear Operations for 2015 and 2014 was as follows: Years Ended December 31, 2015 2014 Revenue $ 2,061,167 $ 1,841,018 Pre-tax income $ 215,150 $ 151,800 DISCONTINUED OPERATIONS Capital Services Operations Transaction Summary —As discussed in Note 2 , on June 30, 2017 we completed the sale of our Capital Services Operations as provided for by the CS Agreement entered into on February 27, 2017. Under the CS Agreement, including its amendment prior to the Closing Date, the purchase price was $700,000 , subject to certain adjustments including a working capital adjustment, whereby the purchase price would be adjusted to the extent actual working capital of the Capital Services Operations on the Closing Date differed from required working capital under the CS Agreement. After giving effect to working capital and other adjustments estimated prior to the Closing Date of approximately $32,600 , we received cash proceeds of approximately $667,400 (approximately $645,500 net of cash sold) on the Closing Date. Based on actual working capital of the Capital Services Operations on the Closing Date, we estimate net final proceeds of approximately $599,000 , including approximately $46,500 for transaction costs and the aforementioned post-closing working capital adjustment. As a result of the aforementioned, during 2017, we recorded a pre-tax charge of approximately $64,800 , and income tax expense of approximately $55,800 resulting from a taxable gain on the transaction (due primarily to the non-deductibility of goodwill). The transaction did not result in any material cash taxes associated with the taxable gain due to the use of previously recorded net operating loss carryforwards. The proceeds received on the Closing Date were used to reduce our outstanding debt. Assets and Liabilities —The carrying values of the major classes of assets and liabilities of the discontinued Capital Services Operations within our Balance Sheets at December 31, 2016 and 2015 were as follows: December 31, 2016 2015 Assets Cash $ 14,477 $ 14,507 Accounts receivable 239,146 274,186 Costs and estimated earnings in excess of billings 153,275 165,003 Other assets 7,834 7,876 Current assets of discontinued operations 414,732 461,572 Property and equipment, net 59,746 64,916 Goodwill (1) 229,607 884,607 Other intangible assets 148,440 165,040 Other assets 24,351 39,487 Non-current assets of discontinued operations 462,144 1,154,050 Total assets of discontinued operations $ 876,876 $ 1,615,622 Liabilities Accounts payable $ 141,028 $ 112,884 Billings in excess of costs and estimated earnings 53,986 67,287 Other liabilities 52,455 50,160 Current liabilities of discontinued operations 247,469 230,331 Other liabilities 5,388 5,921 Non-current liabilities of discontinued operations 5,388 5,921 Total liabilities of discontinued operations $ 252,857 $ 236,252 Noncontrolling interests of discontinued operations $ 6,874 $ 7,484 (1) The carrying value of goodwill for the discontinued Capital Services Operations includes the impact of a $655,000 impairment charge recorded in the fourth quarter 2016 in connection with our annual impairment assessment (discussed in Note 7).

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND OTHER INTANGIBLES	GOODWILL AND OTHER INTANGIBLES Goodwill Summary —At December 31, 2016 and 2015 , our goodwill balances were $2,315,338 and $2,325,248 , respectively, attributable to the excess of the purchase price over the fair value of net assets acquired in connection with our acquisitions. The change in goodwill by reporting segment for 2016 and 2015 was as follows: Engineering & Construction Fabrication Services Total Balance at December 31, 2014 $ 2,339,246 $ 465,415 $ 2,804,661 Impairment charges (described below) (1) (453,100 ) — (453,100 ) Amortization of tax goodwill in excess of book goodwill (3,789 ) (348 ) (4,137 ) Foreign currency translation and other (22,176 ) — (22,176 ) Balance at December 31, 2015 $ 1,860,181 $ 465,067 $ 2,325,248 Amortization of tax goodwill in excess of book goodwill (338 ) (2 ) (340 ) Foreign currency translation and other (9,570 ) — (9,570 ) Balance at December 31, 2016 $ 1,850,273 $ 465,065 $ 2,315,338 (1) At December 31, 2016 , we had approximately $453,100 of cumulative impairment losses, which were recorded in our Engineering & Construction operating group during 2015 related to the sale of our Nuclear Operations on December 31, 2015. As discussed further in Note 2 , goodwill is not amortized to earnings, but instead is reviewed for impairment at least annually at a reporting unit level, absent any indicators of impairment or when other actions require an impairment assessment (such as a change in reporting units). We perform our annual impairment assessment during the fourth quarter of each year based upon balances as of October 1. At October 1, 2016 and prior to the recognition of our Capital Services Operations and Technology Operations as discontinued operations (discussed below), we had the following five reporting units within our four operating groups: • Engineering & Construction —Our Engineering & Construction operating group represented a reporting unit. • Fabrication Services —Our Fabrication Services operating group represented a reporting unit. As of December 31, 2015 , Fabrication Services included three reporting units: Steel Plate Structures, Fabrication & Manufacturing, and Engineered Products. However, during the third quarter 2016, our Steel Plate Structures, Fabrication & Manufacturing and Engineered Products Operations were integrated and operationally combined. As a result, we reevaluated our reporting units within the Fabrication Services operating group and determined that the Fabrication Services operating group represented a single reporting unit subsequent to the reorganization. In conjunction with the reorganization of our Fabrication Services operating group and change in reporting units, we performed a quantitative assessment of goodwill for each of the reporting units immediately before the change in reporting units, and for the new Fabrication Services reporting unit. Based on these quantitative assessments, the fair value of each of the reporting units exceeded their respective net book values, and accordingly, no impairment charge was necessary as a result of the change in reporting units. Our Engineered Products Operations were included within our Technology Operations and classified as a discontinued operation in the third quarter 2017 (discussed below). • Technology —Our Technology operating group represented a reporting unit. This reporting unit was included within our Technology Operations and classified as a discontinued operation in the third quarter 2017 (discussed below). • Capital Services —Our Capital Services operating group included two reporting units: Facilities & Plant Services and Federal Services. These reporting units were included within our Capital Services Operations and classified as a discontinued operation in the first quarter 2017 (discussed below). As a result of the aforementioned, the reporting units of our continuing operations represent our Engineering & Construction operating group and our Fabrication Services operating group (excluding our discontinued Engineered Products Operations). Annual Impairment Assessment —During the fourth quarter 2016, we performed a quantitative assessment of goodwill for each of the aforementioned reporting units as of October 1, 2016. Based on these quantitative assessments, the fair value of our Engineering & Construction, Fabrication Services and Technology reporting units each substantially exceeded their respective net book values, and accordingly, no impairment charge was necessary as a result of our annual impairment assessments. However, we determined that the net book value of the Facilities & Plant Services and Federal Services reporting units each exceeded their respective fair values, indicating that the carrying value of their goodwill was impaired. Our fair value determination for the Facilities & Plant Services and Federal Services reporting units gave consideration to a market indicator of fair value for the reporting units (discussed in Note 19). As a result of the aforementioned, we recorded a goodwill impairment charge of $655,000 for these reporting units ( $581,900 for Facilities & Plant Services and $73,100 for Federal Services). Accordingly, at December 31, 2016, the adjusted carrying value of goodwill for the Facilities & Plant Services and Federal Services reporting units was approximately $112,900 and $116,700 , respectively. The amount of goodwill impairment charge was determined by comparing the carrying value of each reporting unit’s goodwill to their respective implied fair values. The fair values of the Facilities & Plant Services and Federal Services reporting units approximated their respective net book values subsequent to the goodwill impairments. If, based on future assessments our goodwill is deemed to be impaired, the impairment would result in a charge to earnings in the period of impairment. There can be no assurance that future goodwill impairment tests will not result in charges to earnings. Discontinued Operations —During the first quarter 2017, we classified our Capital Services Operations as a discontinued operation (discussed in Note 2 and Note 5 ). Our Capital Services Operations are primarily comprised of our former Capital Services operating group, which included our Facilities & Plant Services and Federal Services reporting units. As a result of the classification of our Capital Services operating group within discontinued operations, all its goodwill (approximately $229,600 , after the aforementioned $655,000 impairment) was allocated to our Capital Services Operations. During the third quarter 2017, we classified our Technology Operations as a discontinued operation (discussed in Note 2 and Note 5 ). Our Technology Operations are primarily comprised of our former Technology operating group and reporting unit and our Engineered Products Operations, representing a portion of our Fabrication Services operating group and reporting unit. As a result of the classification of our Technology reporting unit as a part of our Technology Operations within discontinued operations, all of its goodwill (approximately $297,000 ) was allocated to our Technology Operations. Further, as a result of the classification of our Engineered Products Operations as part of our Technology Operations within discontinued operations, we allocated a portion of the Fabrication Services reporting unit’s goodwill (approximately $200,000 ) to our Technology Operations. The allocation was based on the relative fair values of the Engineered Products Operations and remaining Fabrication Services reporting unit after removal of the Engineered Products Operations. The fair value of the Engineered Products Operations was determined on a basis consistent with the basis used for our annual impairment assessment (discussed in Note 2) and gave consideration to a market indicator of fair value for the Technology Operations. The fair value of the remaining Fabrication Services reporting unit was also determined on a basis consistent with the basis used for our annual impairment assessment. Based on the aforementioned, the fair value of the remaining Fabrication Services reporting unit continued to substantially exceed its net book value, and accordingly, no impairment charge was necessary as a result of the removal of the Engineered Products Operations. Other Intangible Assets —The following table presents our acquired finite-lived intangible assets at December 31, 2016 and 2015 , including the December 31, 2016 weighted-average useful lives for each major intangible asset class and in total: December 31, 2016 December 31, 2015 Weighted Average Life Gross Carrying Amount Accumulated Amortization Gross Carrying Amount Accumulated Amortization Backlog and customer relationships (1) 18 Years $ 93,700 $ (20,073 ) $ 101,686 $ (22,546 ) Process technologies 20 Years 400 (78 ) 400 (58 ) Tradenames 6 Years 15,718 (9,531 ) 15,718 (7,258 ) Total (2) 17 Years $ 109,818 $ (29,682 ) $ 117,804 $ (29,862 ) (1) Backlog and customer relationships intangibles totaling approximately $8,000 became fully amortized during 2016 and were therefore removed from the December 31, 2016 gross carrying and accumulated amortization balances above. (2) The remaining decrease in other intangibles, net during 2016 primarily related to amortization expense of approximately $7,800 . Amortization expense for our intangibles existing at December 31, 2016 is anticipated to be approximately $7,700 , $7,700 , $5,700 , $5,400 and $5,200 for 2017 , 2018 , 2019 , 2020 and 2021 , respectively. As a result of the partial impairment of goodwill for our Capital Services operating group resulting from our fourth quarter annual impairment assessment, we determined that an indicator of impairment existed for the finite-lived intangible assets of our Capital Services operating group, and accordingly, we performed an impairment assessment for these intangible assets during the fourth quarter 2016. Based on our impairment assessment we concluded that the intangible assets were not impaired. We noted no other indicators of impairment during 2016.

Equity Method Investments and Joint Ventures [Abstract]
PARTNERING ARRANGEMENTS	PARTNERING ARRANGEMENTS As discussed in Note 2 , we account for our unconsolidated ventures using either proportionate consolidation, when we meet the applicable accounting criteria to do so, or the equity method. Further, we consolidate any venture that is determined to be a VIE for which we are the primary beneficiary, or which we otherwise effectively control. Proportionately Consolidated Ventures —The following is a summary description of our significant joint ventures which have been accounted for using proportionate consolidation: • CB&I/Zachry— We have a venture with Zachry (CB&I— 50% / Zachry— 50% ) to perform EPC work for two liquefied natural gas (“LNG”) liquefaction trains in Freeport, Texas. Our proportionate share of the venture project value is approximately $2,700,000 . In addition, we have subcontract and risk sharing arrangements with Chiyoda to support our responsibilities to the venture. The costs of these arrangements are recorded in cost of revenue. • CB&I/Zachry/Chiyoda— We have a venture with Zachry and Chiyoda (CB&I— 33.3% / Zachry— 33.3% / Chiyoda— 33.3% ) to perform EPC work for an additional LNG liquefaction train at the aforementioned project site in Freeport, Texas. Our proportionate share of the venture project value is approximately $675,000 . • CB&I/Chiyoda— We have a venture with Chiyoda (CB&I— 50% / Chiyoda— 50% ) to perform EPC work for three LNG liquefaction trains in Hackberry, Louisiana. Our proportionate share of the venture project value is approximately $3,100,000 . The following table presents summarized balance sheet information for our share of our proportionately consolidated ventures: December 31, 2016 2015 CB&I/Zachry Current assets (1) $ 260,934 $ 298,916 Non-current assets 3,204 6,689 Total assets $ 264,138 $ 305,605 Current liabilities (1) $ 379,339 $ 454,943 CB&I/Zachry/Chiyoda Current assets (1) $ 84,279 $ 82,106 Non-current assets 1,969 2,590 Total assets $ 86,248 $ 84,696 Current liabilities (1) $ 73,138 $ 86,124 CB&I/Chiyoda Current assets (1) $ 337,479 $ 424,781 Current liabilities (1) $ 150,179 $ 433,526 (1) Our venture arrangements allow for excess working capital of the ventures to be advanced to the venture partners. Such advances are returned to the ventures for working capital needs as necessary. Accordingly, at a reporting period end a venture may have advances to its partners which are reflected as an advance receivable within current assets of the venture. As summarized in Note 9 , at December 31, 2016 and 2015 , other current assets on the Balance Sheets included approximately $374,800 and $325,000 , respectively, related to our proportionate share of advances from the ventures to our venture partners, and other current liabilities included approximately $394,400 and $334,900 , respectively, related to advances to CB&I from the ventures. Equity Method Ventures —The following is a summary description of our significant joint ventures which have been accounted for using the equity method: • NET Power— We have a venture with Exelon and 8 Rivers Capital (CB&I— 33.3% / Exelon— 33.3% / 8 Rivers Capital— 33.3% ) to commercialize a new natural gas power generation system that recovers the carbon dioxide produced during combustion. NET Power is building a first-of-its-kind demonstration plant which is being funded by contributions and services from the venture partners and other parties. We have determined the venture to be a VIE; however, we do not effectively control NET Power and therefore do not consolidate it. Our cash commitment for NET Power totals $47,300 , and at December 31, 2016 , we had made cumulative investments totaling approximately $37,900 . • CB&I/CTCI— We have a venture with CTCI (CB&I— 50% / CTCI— 50% ) to perform EPC work for a liquids ethylene cracker and associated units in Sohar, Oman. We have determined the venture to be a VIE; however, we do not effectively control the venture and therefore do not consolidate it. Our proportionate share of the venture project value is approximately $1,400,000 . Our venture arrangement allows for excess working capital of the venture to be advanced to the venture partners. Such advances are returned to the venture for working capital needs as necessary. As summarized in Note 9 , at December 31, 2016 , other current liabilities included approximately $147,000 related to advances to CB&I from the venture. Dividends received from our equity method ventures were not material during 2016 , 2015 and 2014 , respectively. We have no other material unconsolidated ventures. Consolidated Ventures— The following is a summary description of our significant joint ventures we consolidate due to their designation as VIEs for which we are the primary beneficiary: • CB&I/Kentz— We have a venture with Kentz (CB&I— 65% / Kentz— 35% ) to perform the structural, mechanical, piping, electrical and instrumentation work on, and to provide commissioning support for, three LNG trains, including associated utilities and a gas processing and compression plant, for the Gorgon LNG project, located on Barrow Island, Australia. Our venture project value is approximately $5,900,000 . • CB&I/AREVA— We have a venture with AREVA (CB&I — 52% / AREVA— 48% ) to design, license and construct a mixed oxide fuel fabrication facility in Aiken, South Carolina. Our venture project value is approximately $5,800,000 . The following table presents summarized balance sheet information for our consolidated ventures: December 31, 2016 2015 CB&I/Kentz Current assets $ 68,867 $ 214,291 Current liabilities $ 87,822 $ 191,471 CB&I/AREVA Current assets $ 16,313 $ 24,269 Current liabilities $ 47,652 $ 65,674 All Other (1) Current assets $ 69,785 $ 78,492 Non-current assets 16,382 18,415 Total assets $ 86,167 $ 96,907 Current liabilities $ 7,748 $ 22,025 (1) Other ventures that we consolidate are not individually material to our financial results and are therefore aggregated as “All Other”. Other— The use of these ventures exposes us to a number of risks, including the risk that our partners may be unable or unwilling to provide their share of capital investment to fund the operations of the venture or complete their obligations to us, the venture, or ultimately, our customer. Differences in opinions or views among venture partners could also result in delayed decision-making or failure to agree on material issues, which could adversely affect the business and operations of the venture. In addition, agreement terms may subject us to joint and several liability for our venture partners, and the failure of our venture partners to perform their obligations could impose additional performance and financial obligations on us. The aforementioned factors could result in unanticipated costs to complete the projects, liquidated damages or contract disputes, including claims against our partners.

(“BofA”), as administrative agent, and BNP Paribas Securities Corp., BBVA Compass, Credit Agricole Corporate and Investment Bank (“Credit Agricole”) and TD Securities, each as syndication agents, which expires in October 2018. The Revolving Facility has a $270,000 financial letter of credit sublimit and has financial and restrictive covenants described further below. The Revolving Facility also includes customary restrictions regarding subsidiary indebtedness, sales of assets, liens, investments, type of business conducted, and mergers and acquisitions, and includes a limitation for dividend payments and share repurchases, among other restrictions. In addition to interest on debt borrowings, we are assessed quarterly commitment fees on the unutilized portion of the facility as well as letter of credit fees on outstanding instruments. The interest, commitment fee, and letter of credit fee percentages are based upon our quarterly leverage ratio. In the event we borrow funds under the facility, interest is assessed at either prime plus an applicable floating margin ( 3.75% and 1.00% , respectively at December 31, 2016 ), or LIBOR plus an applicable floating margin ( 0.77% and 2.00% , respectively at December 31, 2016 ). At December 31, 2016 , we had $100,000 of outstanding borrowings under the facility and $78,251 of outstanding letters of credit under the facility (including $4,680 associated with our discontinued Technology Operations and none of which were financial letters of credit), providing $1,171,749 of available capacity. During 2016 , our weighted average interest rate on borrowings under the facility was approximately 2.3% , inclusive of the applicable floating margin. We have a five -year, $800,000 , committed and unsecured revolving credit facility (the “Second Revolving Facility”) with BofA, as administrative agent, and BNP Paribas Securities Corp., BBVA Compass, Credit Agricole and Bank of Tokyo Mitsubishi UFJ, each as syndication agents, which expires in July 2020. The Second Revolving Facility supplements our Revolving Facility, has a $50,000 financial letter of credit sublimit and has financial and restrictive covenants described further below. In addition to interest on debt borrowings, we are assessed quarterly commitment fees on the unutilized portion of the facility as well as letter of credit fees on outstanding instruments. The interest, commitment fee, and letter of credit fee percentages are based upon our quarterly leverage ratio. In the event we borrow funds under the facility, interest is assessed at either prime plus an applicable floating margin ( 3.75% and 1.00% , respectively at December 31, 2016 ), or LIBOR plus an applicable floating margin ( 0.77% and 2.00% , respectively at December 31, 2016 ). At December 31, 2016 , we had $157,500 of outstanding borrowings and $7,630 of outstanding letters of credit under the facility (including $4,762 associated with our discontinued Technology Operations and including $2,757 of financial letters of credit), providing $634,870 of available capacity. During 2016 , our weighted average interest rate on borrowings under the facility was approximately 4.3% , inclusive of the applicable floating margin. Uncommitted Facilities —We also have various short-term, uncommitted letter of credit and borrowing facilities (the “Uncommitted Facilities”) across several geographic regions of approximately $4,561,950 , of which $563,000 may be utilized for borrowings. At December 31, 2016 , we had $150,000 of outstanding borrowings and $1,635,357 of outstanding letters of credit under these facilities (including $25,044 associated with our discontinued Capital Services Operations and $69,117 associated with our discontinued Technology Operations), providing $2,776,593 of available capacity, of which $413,000 may be utilized for borrowings. During 2016 , our weighted average interest rate on borrowings under the facilities was approximately 1.6% . Term Loans —At December 31, 2016 , we had $300,000 outstanding on a four -year, $1,000,000 unsecured term loan (the “Term Loan”) with BofA as administrative agent. Interest and principal under the Term Loan is payable quarterly in arrears and bears interest at LIBOR plus an applicable floating margin ( 0.77% and 2.00% , respectively at December 31, 2016 ). However, we continue to utilize an interest rate swap to hedge against $290,375 of the outstanding Term Loan, which resulted in a weighted average interest rate of approximately 2.3% during 2016 , inclusive of the applicable floating margin. The balance of the Term Loan was paid February 13, 2017 . The Term Loan has financial and restrictive covenants described further below. At December 31, 2016 , we had $500,000 outstanding on a five -year, $500,000 unsecured term loan (the “Second Term Loan”) with BofA as administrative agent. Interest and principal under the Second Term Loan is payable quarterly in arrears beginning in June 2017 and bears interest at LIBOR plus an applicable floating margin (rates are equivalent to the Term Loan). During 2016 , our weighted average interest rate on the Second Term Loan was approximately 2.3% , inclusive of the applicable floating margin. Future annual maturities for the Second Term Loan are $56,250 , $75,000 , $75,000 and $293,750 for 2017 , 2018 , 2019 , and 2020 , respectively. The Second Term Loan has financial and restrictive covenants described further below. Senior Notes— We have a series of senior notes totaling $800,000 in the aggregate (the “Senior Notes”) with Merrill Lynch, Pierce, Fenner & Smith Incorporated, and Credit Agricole, as administrative agents. The Senior Notes have financial and restrictive covenants described further below. The Senior Notes include Series A through D, which contain the following terms: • Series A—Interest due semi-annually at a fixed rate of 4.15% , with principal of $150,000 due in December 2017 • Series B—Interest due semi-annually at a fixed rate of 4.57% , with principal of $225,000 due in December 2019 • Series C—Interest due semi-annually at a fixed rate of 5.15% , with principal of $275,000 due in December 2022 • Series D—Interest due semi-annually at a fixed rate of 5.30% , with principal of $150,000 due in December 2024 We have senior notes totaling $200,000 (the “Second Senior Notes”) with BofA as administrative agent. Interest is due semi-annually at a fixed rate of 4.53% , with principal of $200,000 due in July 2025. The Second Senior Notes have financial and restrictive covenants described further below. Compliance and Other —On February 24, 2017 , and effective for the period ended December 31, 2016, we amended our Revolving Facility, Second Revolving Facility, Second Term Loan, Senior Notes and Second Senior Notes. The amendments adjusted our maximum leverage ratio from 3.00 to 3.50 and our minimum net worth from $1,736,651 to $1,201,507 . Our maximum leverage ratio will decrease to 3.00 on December 31, 2017, or 45 days subsequent to the closing of the sale of our Capital Services operating group (the “Closing Date”) as described in Note 5 , if earlier. Our required fixed charge ratio remained at 1.75 . The amendments also reduce our Revolving Facility from $1,350,000 to $1,150,000 at the Closing Date. Our amended restrictive covenants continue to include a twelve-month limitation of $250,000 for dividend payments and share repurchases if our leverage ratio exceeds 1.50 (unlimited if our leverage ratio is equal to or below 1.50 ); however, share repurchases and acquisitions are not allowed if our leverage ratio exceeds 3.00 . The amendments to our Senior Notes and Second Senior Notes also include other provisions relating to maintaining our leverage ratio and credit profile. At December 31, 2016, we were in compliance with all our amended financial and restrictive covenants with a leverage ratio of 3.10 , a fixed charge coverage ratio of 3.61 , and net worth of $1,413,538 . During 2016 , maximum outstanding borrowings under our revolving credit and other facilities were approximately $1,444,000 . In addition to providing letters of credit, we also issue surety bonds in the ordinary course of business to support our contract performance. At December 31, 2016 , we had $826,383 of outstanding surety bonds (including $393,250 associated with our discontinued Capital Services Operations and $4,404 associated with our discontinued Technology Operations). Capitalized interest was insignificant for 2016 , 2015 and 2014 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
FINANCIAL INSTRUMENTS	FINANCIAL INSTRUMENTS Derivatives Foreign Currency Exchange Rate Derivatives —At December 31, 2016 , the notional value of our outstanding forward contracts to hedge certain foreign exchange-related operating exposures was approximately $139,100 . These contracts vary in duration, maturing up to five years from period-end. We designate certain of these hedges as cash flow hedges and accordingly, changes in their fair value are recognized in AOCI until the associated underlying operating exposure impacts our earnings. Forward points, which are deemed to be an ineffective portion of the hedges, are recognized within cost of revenue and are not material. Interest Rate Derivatives— We continue to utilize a swap arrangement to hedge against interest rate variability associated with $290,375 of our outstanding $300,000 Term Loan. The swap arrangement has been designated as a cash flow hedge as its critical terms matched those of the Term Loan at inception and through December 31, 2016 . Accordingly, changes in the fair value of the swap arrangement are included in AOCI until the associated underlying exposure impacts our earnings. Financial Instruments Disclosures Fair Value —Financial instruments are required to be categorized within a valuation hierarchy based upon the lowest level of input that is significant to the fair value measurement. The three levels of the valuation hierarchy are as follows: • Level 1 —Fair value is based upon quoted prices in active markets. • Level 2 —Fair value is based upon internally-developed models that use, as their basis, readily observable market parameters. Our derivative positions are classified within level 2 of the valuation hierarchy as they are valued using quoted market prices for similar assets and liabilities in active markets. These level 2 derivatives are valued utilizing an income approach, which discounts future cash flow based upon current market expectations and adjusts for credit risk. • Level 3 —Fair value is based upon internally-developed models that use, as their basis, significant unobservable market parameters. We did not have any level 3 classifications at December 31, 2016 or 2015 . The following table presents the fair value of our foreign currency exchange rate derivatives and interest rate derivatives at December 31, 2016 and 2015 , respectively, by valuation hierarchy and balance sheet classification: December 31, 2016 December 31, 2015 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Derivative Assets (1) Other current assets $ — $ 1,146 $ — $ 1,146 $ — $ 3,344 $ — $ 3,344 Other non-current assets — 82 — 82 — 180 — 180 Total assets at fair value $ — $ 1,228 $ — $ 1,228 $ — $ 3,524 $ — $ 3,524 Derivative Liabilities Other current liabilities $ — $ (3,509 ) $ — $ (3,509 ) $ — $ (7,568 ) $ — $ (7,568 ) Other non-current liabilities — (725 ) — (725 ) — (607 ) — (607 ) Total liabilities at fair value $ — $ (4,234 ) $ — $ (4,234 ) $ — $ (8,175 ) $ — $ (8,175 ) (1) We are exposed to credit risk on our hedging instruments associated with potential counterparty non-performance, and the fair value of our derivatives reflects this credit risk. The total level 2 assets at fair value above represent the maximum loss that we would incur on our outstanding hedges if the applicable counterparties failed to perform according to the hedge contracts. To help mitigate counterparty credit risk, we transact only with counterparties that are rated as investment grade or higher and monitor all counterparties on a continuous basis. The carrying values of our cash and cash equivalents (primarily consisting of bank deposits), accounts receivable and accounts payable approximate their fair values because of the short-term nature of these instruments. At December 31, 2016 , the fair values of our Term Loan and Second Term Loan, based upon the current market rates for debt with similar credit risk and maturities, approximated their carrying values as interest is based upon LIBOR plus an applicable floating margin. Our Senior Notes and Second Senior Notes are categorized within level 2 of the valuation hierarchy. Our Senior Notes had a total fair value of approximately $785,700 and $772,600 at December 31, 2016 and 2015 , respectively, based on current market rates for debt with similar credit risk and maturities. Our Second Senior Notes had a total fair value of approximately $206,400 and $203,500 at December 31, 2016 and 2015 , respectively, based on current market rates for debt with similar credit risk and maturities.

Retirement Benefits [Abstract]
RETIREMENT BENEFITS	RETIREMENT BENEFITS Defined Contribution Plans We sponsor multiple defined contribution plans for eligible employees with various features, including voluntary employee pre-tax and Roth-based contributions, and Company matching and other contributions. During 2016 , 2015 and 2014 , we expensed $57,495 , $40,220 and $50,107 , respectively, for these plans. In addition, we sponsor multiple defined contribution plans that cover eligible employees for which we do not provide contributions. The cost of these plans was not significant to us in 2016 , 2015 or 2014 . Defined Benefit Pension and Other Postretirement Plans We sponsor various defined benefit pension plans covering eligible employees and provide specific post retirement benefits for eligible retired U.S. employees and their dependents through health care and life insurance benefit programs. These plans may be changed or terminated by us at any time. The following tables present combined information for our defined benefit pension and other postretirement plans: Components of Net Periodic Benefit Cost Pension Plans Other Postretirement Plans 2016 2015 2014 2016 2015 2014 Service cost $ 8,531 $ 9,757 $ 8,251 $ 704 $ 791 $ 1,037 Interest cost 21,668 21,949 31,350 1,361 1,545 2,279 Expected return on plan assets (25,193 ) (27,136 ) (34,887 ) — — — Amortization of prior service credits (606 ) (609 ) (468 ) — — — Recognized net actuarial losses (gains) 5,074 6,855 4,104 (3,361 ) (2,696 ) (863 ) Net periodic benefit cost (income) $ 9,474 $ 10,816 $ 8,350 $ (1,296 ) $ (360 ) $ 2,453 Change in Projected Benefit Obligation Pension Plans Other Postretirement Plans 2016 2015 2016 2015 Projected benefit obligation at beginning of year $ 767,456 $ 878,003 $ 30,948 $ 51,458 Service cost 8,531 9,757 704 791 Interest cost 21,668 21,949 1,361 1,545 Actuarial loss (gain) (1) 120,699 (42,357 ) 2,702 (20,863 ) Plan participants’ contributions 2,657 2,649 502 452 Benefits paid (34,298 ) (30,878 ) (2,810 ) (2,435 ) Currency translation (2) (71,365 ) (71,667 ) — — Projected benefit obligation at end of year $ 815,348 $ 767,456 $ 33,407 $ 30,948 Change in Plan Assets Pension Plans Other Postretirement Plans 2016 2015 2016 2015 Fair value of plan assets at beginning of year $ 668,177 $ 738,580 $ — $ — Actual return on plan assets 75,241 880 — — Benefits paid (34,298 ) (30,878 ) (2,810 ) (2,435 ) Employer contributions (3) 15,757 15,978 2,308 1,983 Plan participants’ contributions 2,657 2,649 502 452 Currency translation (2) (63,696 ) (59,032 ) — — Fair value of plan assets at end of year $ 663,838 $ 668,177 $ — $ — Funded status $ (151,510 ) $ (99,279 ) $ (33,407 ) $ (30,948 ) Balance Sheet Position Pension Plans Other Postretirement Plans 2016 2015 2016 2015 Prepaid benefit cost within other non-current assets $ 2,798 $ 13,581 $ — $ — Accrued benefit cost within other current liabilities (2,098 ) (2,167 ) (2,476 ) (2,432 ) Accrued benefit cost within other non-current liabilities (152,210 ) (110,693 ) (30,931 ) (28,516 ) Net funded status recognized $ (151,510 ) $ (99,279 ) $ (33,407 ) $ (30,948 ) Unrecognized net prior service credits $ (3,101 ) $ (3,801 ) $ — $ — Unrecognized net actuarial losses (gains) 183,282 131,085 (25,508 ) (31,571 ) Accumulated other comprehensive loss (income), before taxes (4) $ 180,181 $ 127,284 $ (25,508 ) $ (31,571 ) (1) The actuarial pension plan loss for 2016 was primarily associated with a decrease in discount rate assumptions for our pension plans. The actuarial pension plan gain for 2015 was primarily associated with an increase in the discount rate assumptions for our pension plans. The actuarial other postretirement plan gain for 2015 was primarily associated with an increase in the discount rate assumptions and a decrease in the percent of retiring employees electing medical coverage for our other postretirement plan. (2) The currency translation loss for 2016 and 2015 was primarily associated with the strengthening of the U.S. Dollar against the currencies associated with our international pension plans, primarily the Euro and British Pound. (3) During 2017 , we expect to contribute approximately $15,900 and $2,500 to our pension and other postretirement plans, respectively. (4) During 2017 , we expect to recognize approximately $(600) and $4,700 of previously unrecognized net prior service pension credits and net actuarial pension losses, respectively. Accumulated Benefit Obligation —At December 31, 2016 and 2015 , the accumulated benefit obligation for all defined benefit pension plans was $799,619 and $768,127 , respectively. The following table includes summary information for those defined benefit plans with an accumulated benefit obligation in excess of plan assets: December 31, 2016 2015 Projected benefit obligation $ 704,709 $ 657,027 Accumulated benefit obligation $ 688,980 $ 657,698 Fair value of plan assets $ 550,399 $ 544,168 Plan Assumptions —The following table presents the weighted-average assumptions used to measure our defined benefit pension and other postretirement plans: Pension Plans Other Postretirement Plans 2016 2015 2016 2015 Weighted-average assumptions used to determine benefit obligations at December 31, Discount rate 2.13 % 2.99 % 4.15 % 4.47 % Rate of compensation increase (1) 2.35 % 2.35 % n/a n/a Weighted-average assumptions used to determine net periodic benefit cost for the years ended December 31, Discount rate 2.99 % 2.68 % 4.47 % 4.13 % Expected long-term rate of return on plan assets (2) 3.93 % 3.86 % n/a n/a Rate of compensation increase (1) 2.35 % 2.35 % n/a n/a (1) The rate of compensation increase relates solely to the defined benefit plans that factor compensation increases into the valuation. (2) The expected long-term rate of return on plan assets was derived using historical returns by asset category and expectations of future performance. Benefit Payments —The following table includes the expected defined benefit and other postretirement plan payments for the next 10 years: Year Pension Plans Other Postretirement Plans 2017 $ 34,882 $ 2,476 2018 $ 30,966 $ 2,471 2019 $ 31,128 $ 2,446 2020 $ 31,789 $ 2,408 2021 $ 32,398 $ 2,337 2022-2026 $ 169,850 $ 10,820 Plan Assets —Our investment strategy for defined benefit plan assets seeks to optimize the proper risk-return relationship considered appropriate for each respective plan’s investment goals, using a global portfolio of various asset classes diversified by market segment, economic sector and issuer. The primary goal is to optimize the asset mix to fund future benefit obligations, while managing various risk factors and each plan’s investment return objectives. Our defined benefit plan assets in the U.S. are invested in well-diversified portfolios of equity (including U.S. large, mid and small-capitalization and international equities) and fixed income securities (including corporate and government bonds). Non-U.S. defined benefit plan assets are similarly invested in well-diversified portfolios of equity, fixed income and other securities. At December 31, 2016 , our target weighted-average asset allocations by asset category were: equity securities ( 35% - 40% ), fixed income securities ( 60% - 65% ), and other investments ( 0% - 5% ). Our pension assets are categorized within the valuation hierarchy based upon the lowest level of input that is significant to the fair value measurement. Assets that are valued using quoted prices are classified within level 1 of the valuation hierarchy, assets that are valued using internally-developed models that use, as their basis, readily observable market parameters, are classified within level 2 of the valuation hierarchy, and assets that are valued based upon models with significant unobservable market parameters are classified within level 3 of the valuation hierarchy. The following tables present the fair value of our plan assets by investment category and valuation hierarchy level at December 31, 2016 and 2015 : December 31, 2016 Level 1 Level 2 Level 3 Total Asset Category Equity Securities: Global Equities and Cash $ 3,259 $ — $ — $ 3,259 International Funds (1) — 148,794 — 148,794 Emerging Markets Growth Funds — 17,046 — 17,046 U.S. Equity Funds — 13,767 — 13,767 Fixed Income Securities: International Government Bonds (2) — 169,781 — 169,781 International Corporate Bonds (3) — 102,866 — 102,866 International Mortgage Funds (4) — 58,017 — 58,017 All Other Fixed Income Securities (5) — 46,537 — 46,537 Other Investments: Asset Allocation Funds (6) — 103,771 — 103,771 Total Assets at Fair Value $ 3,259 $ 660,579 $ — $ 663,838 December 31, 2015 Level 1 Level 2 Level 3 Total Asset Category Equity Securities: Global Equities and Cash $ 2,278 $ — $ — $ 2,278 International Funds (1) — 161,032 — 161,032 U.S. Equity Funds — 20,158 — 20,158 Emerging Markets Growth Funds — 15,505 — 15,505 Fixed Income Securities: International Government Bonds (2) — 238,165 — 238,165 International Corporate Bonds (3) — 88,463 — 88,463 International Mortgage Funds (4) — — — — All Other Fixed Income Securities (5) — 63,085 — 63,085 Other Investments: Asset Allocation Funds (6) — 79,491 — 79,491 Total Assets at Fair Value $ 2,278 $ 665,899 $ — $ 668,177 The following provides descriptions for plan asset categories with significant balances in the tables above: (1) Investments in various funds that track international indices. (2) Investments in predominately EU government securities and U.K. Treasury securities with credit ratings primarily AAA. (3) Investments in European and U.K. fixed interest securities with credit ratings of primarily BBB and above. (4) Investments in international mortgage funds. (5) Investments predominantly in various international fixed income obligations that are individually insignificant. (6) Investments in fixed income securities, equities and alternative asset classes, including commodities and property assets. Health Care Cost Inflation —As noted above, we provide specific postretirement health care benefits for eligible retired U.S. employees and their dependents. Eligible current and future retirees are covered by a defined fixed dollar benefit, under which our costs for each participant are fixed based upon prior years of employee service. Since 2011, new employees are not eligible for these post-retirement health care benefits. Additionally, there is a closed group of retirees for which we assume some or all of the cost of coverage. For this group, health care cost trend rates are projected at annual rates ranging from 6.0% in 2017 down to 5.0% in 2021 and beyond. A change in the assumed health care cost trends by one percentage point is estimated to have an immaterial impact on the total service and interest cost components of net postretirement health care cost for 2016 and the accumulated postretirement benefit obligation at December 31, 2016 . Multi-Employer Pension Plans —We contribute to certain union sponsored multi-employer defined benefit pension plans in the U.S. and Canada. Benefits under these plans are generally based upon years of service and compensation levels. Under U.S. legislation regarding such pension plans, the risks of participation are different than single-employer pension plans as (1) assets contributed to the plan by a company may be used to provide benefits to participants of other companies, (2) if a participating company discontinues contributions to a plan, other participating companies may have to cover any unfunded liability that may exist, and (3) a company is required to continue funding its proportionate share of a plan’s unfunded vested benefits in the event of withdrawal (as defined by the legislation) from a plan or plan termination. The following table provides additional information regarding our significant multi-employer defined benefit pension plans, including the funding level of each plan (or zone status, as defined by the Pension Protection Act), whether actions to improve the funding level of the plan have been implemented, where required (a funding improvement plan (“FIP”) or rehabilitation plan (“RP”), and our contributions to each plan and total contributions for 2016 , 2015 and 2014 , among other disclosures: EIN/Plan Number Plan Year End Pension Protection Act (% Funded) (1) FIP/RP Plan (1) Total Company Contributions (2) Expiration Date of Collective- Bargaining Agreement (3) Pension Fund 2016 2015 2016 2015 2014 Boilermaker-Blacksmith National Pension Trust 48-6168020-001 12/31 65%-80% 65%-80% Yes $ 26,375 $ 23,079 $ 20,602 Various Plumbers and Pipefitters National Pension Fund 52-6152779-001 6/30 65%-80% 65%-80% Yes 2,241 2,144 1,176 Various Utah Pipe Trades Pension Trust Fund 51-6077569-001 12/31 >80% >80% No 3,372 5,522 664 07/19 Twin City Carpenters and Joiners Pension Fund 41-6043137-001 12/31 65%-80% 65%-80% Yes 1,295 5,469 6,010 04/19 Twin City Ironworkers Pension Plan 41-6084127-001 12/31 >80% >80% No 731 2,102 2,791 04/19 Middle Tennessee Carpenters and Millwrights Pension Fund (4) 62-6101275-001 4/30 >80% >80% No — 6,524 2,881 Various Southern Ironworkers Pension Fund (4) 59-6227091-001 12/31 >80% >80% No — 3,458 1,191 Various Plumbers and Steamfitters Local 150 Pension Fund (4) 58-6116699-001 12/31 >80% >80% No — 3,510 1,502 Various Boilermakers’ National Pension Plan (Canada) 366708 12/31 N/A N/A N/A 6,709 8,645 10,795 04/19 All Other (5) 19,216 19,110 13,477 Total $ 59,939 $ 79,563 $ 61,089 (1) Pension Protection Act Zone Status and FIP/RP plans are applicable to our U.S.-registered plans only, as these terms are not defined within Canadian pension legislation. In the U.S., plans funded less than 65% are in the red zone, plans funded at least 65% , but less than 80% are in the yellow zone, and plans funded at least 80% are in the green zone. The requirement for FIP or RP plans in the U.S. is based on the funding level or zone status of the applicable plan. (2) Our 2016 contributions as a percentage of total plan contributions were not available for any of our plans. For 2015 and 2014 , our contributions to the Utah Pipe Trades Pension Trust Fund, the Twin City Carpenters and Joiners Pension Fund, the Twin City Ironworkers Pension Plan, the Southern Ironworkers Pension Fund, the Plumbers and Steamfitters Local 150 Pension Fund and the Boilermakers’ National Pension Plan (Canada) each exceeded 5% of total plan contributions. The level of our contributions to each plan noted above varies from period to period based upon the level of work being performed that is covered under the applicable collective-bargaining agreement. (3) The expiration dates of our labor agreements associated with the plans noted as “Various” above vary based upon the duration of the applicable projects. (4) The contributions in 2015 and 2014 were associated with plans that were included with our former Nuclear Operations, which were sold on December 31, 2015. (5) Our remaining contributions are to various U.S. and Canadian plans, which are individually immaterial. We also contribute to our multi-employer plans for annuity benefits covered under the defined contribution portion of the plans as well as health benefits. We made contributions to our multi-employer plans of $49,932 , $57,364 and $45,977 during 2016 , 2015 and 2014 , respectively, for these additional benefits.

COMMITMENTS AND CONTINGENCIES

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Leases —Certain facilities and equipment, including project-related field equipment, are rented under operating leases that expire at various dates through 2035. Rent expense for operating leases was $90,113 , $123,805 and $118,199 for 2016 , 2015 and 2014 , respectively. Future minimum payments under non-cancelable operating leases having initial terms of one year or more are as follows: Year Amount 2017 $ 56,948 2018 44,156 2019 36,362 2020 28,936 2021 23,835 Thereafter 89,761 Total $ 279,998 Certain lease agreements contain escalation provisions based upon specific future inflation indices which could impact the future minimum payments presented above. The costs related to leases with an initial term of less than one year have been reflected in rent expense but have been excluded from the future minimum payments presented above. Legal Proceedings General —We have been and may from time to time be named as a defendant in legal actions claiming damages in connection with engineering and construction projects, technology licenses, other services we provide, and other matters. These are typically claims that arise in the normal course of business, including employment-related claims and contractual disputes or claims for personal injury or property damage which occur in connection with services performed relating to project or construction sites. Contractual disputes normally involve claims relating to the timely completion of projects, performance of equipment or technologies, design or other engineering services or project construction services provided by us. We do not believe that any of our pending contractual, employment-related personal injury or property damage claims and disputes will have a material adverse effect on our results of operations, financial position or cash flow. See Note 17 for additional discussion of claims associated with our projects. Project Arbitration Matter —The customer for one of our large cost-reimbursable projects has filed a request for arbitration with the International Chamber of Commerce, alleging cost overruns on the project. The customer has not provided evidence to substantiate its allegations and we believe all amounts incurred and billed on the project, including outstanding receivables of approximately $231,000 as of December 31, 2016 , are contractually due under the provisions of our contract and are recoverable, but have been classified as a non-current asset on our Balance Sheet as we do not anticipate collection within the next year. We do not believe a risk of material loss is probable related to this matter, and accordingly, no amounts have been accrued. While it is possible that a loss may be incurred, we are unable to estimate the range of potential loss, if any. Further, we have asserted counterclaims for our outstanding receivables. Dispute Related to Sale of Nuclear Operations —As discussed further in Note 4 , on December 31, 2015, we sold our Nuclear Operations to WEC. In connection with the transaction, a customary post-closing purchase price adjustment mechanism was negotiated between CB&I and WEC (the “Parties”) to account for any difference between target working capital and actual working capital as finally determined. On April 28, 2016, WEC delivered to us a purported closing statement estimating closing working capital to be negative $976,506 , which was $2,150,506 less than target working capital. In contrast, we calculated closing working capital to be $1,601,805 , which is $427,805 greater than target working capital. On July 21, 2016, we filed a complaint against WEC in the Court of Chancery in the State of Delaware (the “Court”) seeking a declaration that WEC has no remedy for the vast majority of its claims and requesting an injunction barring WEC from bringing such claims. On December 2, 2016, the Court granted WEC’s motion for judgment on the pleadings and dismissed our complaint, stating that the dispute should follow the dispute resolution process as set forth in the sales agreement. We have filed an appeal of the Court’s ruling to the Delaware Supreme Court which is now in the briefing stages. The Parties have selected an independent auditor for the dispute resolution process and we must simultaneously move forward with this process while the appeal is pursued. We do not believe a risk of material loss is probable related to this matter, and accordingly, no amounts have been accrued. While it is possible that a loss may be incurred, we are unable to estimate the range of potential loss, if any. We intend to vigorously pursue this litigation and our rights under the purchase agreement. Asbestos Litigation —We are a defendant in lawsuits wherein plaintiffs allege exposure to asbestos due to work we may have performed at various locations. We have never been a manufacturer, distributor or supplier of asbestos products. Over the past several decades and through December 31, 2016 , we have been named a defendant in lawsuits alleging exposure to asbestos involving approximately 6,000 plaintiffs and, of those claims, approximately 1,200 claims were pending and 4,800 have been closed through dismissals or settlements. Over the past several decades and through December 31, 2016 , the claims alleging exposure to asbestos that have been resolved have been dismissed or settled for an average settlement amount of approximately two thousand dollars per claim. We review each case on its own merits and make accruals based upon the probability of loss and our estimates of the amount of liability and related expenses, if any. While we have seen an increase in the number of recent filings, especially in one specific venue, we do not believe the increase or any unresolved asserted claims will have a material adverse effect on our future results of operations, financial position or cash flow, and at December 31, 2016 , we had approximately $9,200 accrued for liability and related expenses. With respect to unasserted asbestos claims, we cannot identify a population of potential claimants with sufficient certainty to determine the probability of a loss and to make a reasonable estimate of liability, if any. While we continue to pursue recovery for recognized and unrecognized contingent losses through insurance, indemnification arrangements or other sources, we are unable to quantify the amount, if any, that we may expect to recover because of the variability in coverage amounts, limitations and deductibles, or the viability of carriers, with respect to our insurance policies for the years in question. Environmental Matters — Our operations are subject to extensive and changing U.S. federal, state and local laws and regulations, as well as the laws of other countries, that establish health and environmental quality standards. These standards, among others, relate to air and water pollutants and the management and disposal of hazardous substances and wastes. We are exposed to potential liability for personal injury or property damage caused by any release, spill, exposure or other accident involving such pollutants, substances or wastes. In connection with the historical operation of our facilities, including those associated with acquired operations, substances which currently are or might be considered hazardous were used or disposed of at some sites that will or may require us to make expenditures for remediation. In addition, we have agreed to indemnify parties from whom we have purchased or to whom we have sold facilities for certain environmental liabilities arising from acts occurring before the dates those facilities were transferred. We believe we are in compliance, in all material respects, with environmental laws and regulations and maintain insurance coverage to mitigate our exposure to environmental liabilities. We do not believe any environmental matters will have a material adverse effect on our future results of operations, financial position or cash flow. We do not anticipate we will incur material capital expenditures for environmental controls or for the investigation or remediation of environmental conditions during 2017 or 2018 . Letters of Credit/Surety Bonds — In the ordinary course of business, we may obtain surety bonds and letters of credit, which we provide to our customers to secure advance payment or our performance under our contracts, or in lieu of retention being withheld on our contracts. In the event of our non-performance under a contract and an advance being made by a bank pursuant to a draw on a letter of credit, the advance would become a borrowing under a credit facility and thus our direct obligation. Where a surety incurs such a loss, an indemnity agreement between the parties and us may require payment from our excess cash or a borrowing under our credit facilities. When a contract is completed, the contingent obligation terminates and the bonds or letters of credit are returned. See Note 10 for further discussion of our letters of credit and surety bonds. Insurance —We have elected to retain portions of future losses, if any, through the use of deductibles and self-insured retentions for our exposures related to third party liability and workers’ compensation. Liabilities in excess of these amounts are the responsibilities of an insurance carrier. To the extent we are self-insured for these exposures, reserves (see Note 9 ) have been provided based upon our best estimates, with input from our legal and insurance advisors. Changes in assumptions, as well as changes in actual experience, could cause these estimates to change in the near-term. We believe that reasonably possible losses, if any, for these matters, to the extent not otherwise disclosed and net of recorded reserves, will not have a material adverse effect on our future results of operations, financial position or cash flow. At December 31, 2016 , we had outstanding surety bonds and letters of credit of $89,743 relating to our insurance programs. Income Taxes —Income tax and associated interest and penalty reserves, where applicable, are recorded in those instances where we consider it more likely than not that additional tax will be due in excess of amounts reflected in income tax returns filed worldwide, irrespective of whether or not we have received tax assessments. We continually review our exposure to additional income tax obligations and, as further information is known or events occur, changes in our tax and interest reserves may be recorded within income tax expense and interest expense, respectively.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
EQUITY-BASED INCENTIVE PLANS	EQUITY-BASED INCENTIVE PLANS General — Under our equity-based incentive plans (our “Incentive Plans”), we can issue shares to employees and directors in the form of restricted stock units (“RSUs”), performance based shares (including those based upon financial or stock price performance) and stock options. Our Incentive Plans are administered by the Organization and Compensation Committee of our Supervisory Board, which selects those employees eligible to receive awards and determines the number of shares or stock options subject to each award, as well as the terms, conditions, performance measures, and other provisions of the award. Compensation expense related to our Incentive Plans was $36,921 , $53,086 and $64,613 for 2016 , 2015 and 2014 , respectively (including $2,374 , $4,203 and $4,555 , respectively, associated with our discontinued Capital Services Operations and $3,862 , $4,475 and $6,267 , respectively, associated with our discontinued Technology Operations). At December 31, 2016 , 5,979 authorized shares remained available under our Incentive Plans for future RSU, performance based share, or stock option grants. Under our employee stock purchase plan (“ESPP”), employees may make quarterly purchases of shares at a discount through regular payroll deductions for up to 8% of their compensation. The shares are purchased at 85% of the closing price per share on the first trading day following the end of the calendar quarter. Compensation expense related to our ESPP, representing the difference between the fair value on the date of purchase and the price paid, was $2,499 , $3,042 and $3,143 for 2016 , 2015 and 2014 , respectively (including $418 , $535 and $583 , respectively, associated with our discontinued Capital Services Operations and $291 , $316 and $239 , respectively, associated with our discontinued Technology Operations). At December 31, 2016 , 2,757 authorized shares remained available for purchase under the ESPP. Total stock-based compensation expense for our Incentive Plans and ESPP was $39,420 , $56,128 and $67,756 for 2016 , 2015 and 2014 , respectively (including $2,792 , $4,738 and $5,138 , respectively, associated with our discontinued Capital Services Operations and $4,153 , $4,791 and $6,506 , respectively, associated with our discontinued Technology Operations). At December 31, 2016 , there was $44,540 of unrecognized compensation cost related to share-based grants (including $4,437 associated with our discontinued Capital Services Operations and $3,003 associated with our discontinued Technology Operations), which is expected to be recognized over a weighted-average period of 1.7 years. We receive a tax deduction during the period in which certain options are exercised, generally for the difference in the option exercise price and the price of the shares at the date of exercise (“intrinsic value”). Additionally, we receive a tax deduction upon the vesting of RSUs and performance based shares for the price of the shares at the date of vesting. Our total recognized tax benefit based on our compensation expense was $10,377 , $16,924 and $19,394 for 2016 , 2015 and 2014 , respectively (including $527 , $854 and $379 , respectively, associated with our discontinued Capital Services Operations and $477 , $680 and $776 , respectively, associated with our discontinued Technology Operations). The amount of tax deductions in excess of accumulated tax benefits recognized is reflected as a financing cash flow. RSUs — Our RSU awards may not be sold or otherwise transferred until certain restrictions have lapsed, which is generally over a four -year graded vesting period. The total initial fair value for these awards is determined based upon the market price of our stock at the grant date applied to the total number of shares that we anticipate will vest. This fair value is expensed on a straight-line basis over the vesting period, subject to retirement eligibility expense acceleration, where applicable. RSUs granted to directors vest, and are expensed, over one year. The following table presents RSU activity for 2016 : Shares Weighted-Average Grant-Date Fair Value per Share Nonvested RSUs Balance at December 31, 2015 1,385 $ 51.65 Granted 1,021 $ 33.19 Vested (492 ) $ 50.99 Forfeited (80 ) $ 41.51 Balance at December 31, 2016 1,834 $ 41.99 Directors’ RSUs Balance at December 31, 2015 28 $ 49.55 Granted 37 $ 38.18 Vested (28 ) $ 49.55 Balance at December 31, 2016 37 $ 38.18 During 2015 , 1,043 RSUs (including 28 directors’ shares subject to restrictions) were granted with a weighted-average grant-date fair value per share of $42.39 . During 2014 , 535 RSUs (including 17 directors’ shares subject to restrictions) were granted with a weighted-average grant-date fair value per share of $80.41 . The total fair value of RSUs that vested during 2016 , 2015 and 2014 was $26,469 , $28,081 and $17,093 , respectively. Performance Based Shares —Our performance based share awards are subject to the achievement of specified Company performance targets, including financial performance, stock price performance relative to industry peers or stock price performance relative to a construction industry index. • Financial Performance Based Grants —Financial performance based share awards are based upon EPS and generally vest over three years. The total initial fair value for these awards is determined based upon the market price of our stock at the grant date applied to the total number of shares that we anticipate will vest. This fair value is expensed over the vesting period based on the level of payout expected to be achieved, subject to retirement eligibility expense acceleration, where applicable. As a result of financial performance conditions met during 2016 , we recognized $2,020 of compensation expense (including $187 associated with our discontinued Capital Services Operations and $187 associated with our discontinued Technology Operations). During 2016 , 2015 and 2014 , financial performance based shares totaling 665 , 702 and 312 , respectively, were granted with a weighted-average grant-date fair value per share of $33.56 , $41.67 and $79.86 , respectively. During 2016 , upon vesting and achievement of certain performance goals, we distributed 370 financial performance based shares with a weighted-average grant-date fair value per share of $66.10 . The total fair value of financial performance based share awards that vested during 2016 , 2015 and 2014 was $24,446 , $23,463 and $50,244 , respectively. • Stock Performance Based Grants —Stock performance based share awards are based upon stock price performance relative to industry peers or a construction industry index, and generally vest over three years. The total initial fair value for these awards is determined based upon a Monte Carlo simulation value at the grant date applied to the total number of granted target shares. This fair value is expensed ratably over the vesting period, and during 2016 , we recognized $2,908 of compensation expense (including $135 associated with our discontinued Capital Services Operations and $176 associated with our discontinued Technology Operations). During 2016 , 166 stock performance based shares were granted with a weighted-average grant-date fair value per share of $37.41 and was based upon a risk-free interest rate of 0.86% , historical volatility of 38% and a remaining performance period of 2.9 years. During 2015 , 130 stock performance-based shares were granted with a weighted-average grant-date fair value per share of $37.35 and was based upon a risk-free interest rate of 1.10% , an expected dividend yield of 0.69% , historical volatility of 39% and a remaining performance period of 3.9 years (as these shares cliff vest at the end of four years). The risk-free interest rate was based on the U.S. Treasury yield curve on the grant date, expected dividend yield was based on dividend levels at the grant date, expected volatility was based on the historical volatility of our stock, and the expected life of shares granted represents the longest remaining performance period from the grant date. There were no stock performance based shares granted prior to 2015 and there were no vestings in 2016 or 2015 . Stock Options — Stock options are generally granted with an exercise price equivalent to the market price of our stock on the date of grant and expire after 10 years. Options granted to employees generally vest over a period ranging from three to seven years. The total initial fair value for option awards is determined based upon the calculated Black-Scholes fair value of each stock option at the date of grant applied to the total number of options that we anticipate will vest. This fair value is expensed on a straight-line basis over the estimated vesting period, subject to retirement eligibility expense acceleration, where applicable. There were no options granted during 2016 , 2015 or 2014 . The aggregate intrinsic value of options exercised was $533 , $1,126 and $12,218 for 2016 , 2015 and 2014 , respectively. During 2016 , we received net cash proceeds of $1,525 , and realized an actual income tax benefit of $147 , from the exercise of stock options. The following table presents stock option activity for 2016 : Shares Weighted Average Exercise Price per Share Weighted Average Remaining Contractual Life (in Years) Aggregate Intrinsic Value Outstanding options at December 31, 2015 680 $ 21.32 Exercised (59 ) $ 26.06 Forfeited / Expired (23 ) $ 57.38 Outstanding options at December 31, 2016 (1) 598 $ 19.47 2.0 $ 9,361 Exercisable options at December 31, 2016 575 $ 19.21 1.9 $ 9,217 (1) We estimate that 596 of these options will ultimately vest. These options have a weighted-average exercise price per share of $19.45 , a weighted-average remaining contractual life of 2.0 years and a current aggregate intrinsic value of $9,350 .

The following is a reconciliation of income taxes at The Netherlands’ (our country of domicile) statutory rate to income tax benefit (expense) for 2016 , 2015 and 2014 : Years Ended December 31, 2016 2015 2014 Income tax (expense) benefit at statutory rate (25.0% for 2016, 2015 and 2014) $ (56,766 ) $ 190,914 $ (176,243 ) U.S. State income taxes (5,151 ) (4,700 ) (7,115 ) Non-deductible meals and entertainment (8,123 ) (8,416 ) (6,505 ) Non-U.S. valuation allowance established (10,119 ) (2,588 ) (12,551 ) Non-U.S. valuation allowance utilized 18,782 5,210 12,845 Statutory tax rate differential 14,623 118,592 (23,110 ) Branch and withholding taxes (net of tax benefit) — 659 (162 ) Unremitted earnings of subsidiaries 64,376 (10,369 ) — Noncontrolling interests 20,165 19,427 22,094 Non-deductible goodwill impairment — (158,585 ) — Non taxable interest income 18,856 — — Other, net 4,738 4,859 (10,306 ) Income tax benefit (expense) $ 61,381 $ 155,003 $ (201,053 ) Effective tax rate (27.0 )% 20.3 % 28.5 % Deferred Taxes —The principal temporary differences included in deferred income taxes reported on the December 31, 2016 and 2015 Balance Sheets were as follows: December 31, 2016 2015 Deferred Tax Assets U.S. Federal operating losses and credits $ 595,630 $ 626,232 U.S. State operating losses and credits 203,165 195,996 Non-U.S. operating losses 50,410 56,612 Contract revenue and cost 55,748 63,876 Employee compensation and benefit plan reserves 80,733 75,754 Insurance and legal reserves 16,209 25,215 Disallowed interest 117,558 124,876 Other 64,810 9,520 Total deferred tax assets $ 1,184,263 $ 1,178,081 Valuation allowance (160,568 ) (167,053 ) Net deferred tax assets $ 1,023,695 $ 1,011,028 Deferred Tax Liabilities Investment in foreign subsidiaries $ (14,644 ) $ (79,021 ) Depreciation and amortization (291,722 ) (308,619 ) Net deferred tax liabilities $ (306,366 ) $ (387,640 ) Net total deferred tax assets $ 717,329 $ 623,388 At December 31, 2016 , we did not provide deferred income taxes on temporary differences of approximately $397,000 resulting primarily from earnings of our U.S. subsidiaries and certain foreign subsidiaries which are indefinitely reinvested. The reversal of these temporary differences could result in additional tax; however, it is not practicable to estimate the amount of any unrecognized deferred income tax liabilities at this time. Deferred income taxes are provided as necessary with respect to earnings that are not indefinitely reinvested. On a periodic and ongoing basis we evaluate our DTAs and assess the appropriateness of our valuation allowances (“VA”). In assessing the need for a VA, we consider both positive and negative evidence related to the likelihood of realization of the DTAs. If, based on the weight of available evidence, our assessment indicates that it is more likely than not that a DTA will not be realized, we record a VA. Our assessments include, among other things, the value and quality of our backlog, evaluations of existing and anticipated market conditions, analysis of recent and historical operating results and projections of future results, strategic plans and alternatives for associated operations, as well as asset expiration dates, where applicable. If the factors upon which we based our assessment of realizability of our DTAs differ materially from our expectations, including future operating results being lower than our current estimates, our future assessments could be impacted and result in an increase in VA and increase in tax expense. Income tax expense for 2016 benefited by approximately $8,700 from the release of VA for our Non-U.S. net operating losses (“NOL(s)”) and by approximately $67,000 from the reversal of a deferred tax liability associated with historical earnings of a non-U.S. subsidiary for which the earnings are no longer anticipated to be subject to tax. Income tax expense for 2015 was impacted by approximately $62,600 , primarily due to the establishment of VA against U.S.-State NOLs generated in 2015 as a result of the impact of the sale of our Nuclear Operations (approximately $58,000 ). Income tax expense for 2015 also reflects the non-deductibility of the goodwill impairment for the period. At December 31, 2016 , we had total Non-U.S. NOLs of $221,500 , including $117,500 in the U.K. and $104,000 in other jurisdictions. We believe it is more likely than not that all of the U.K. NOLs will be utilized. We believe it is more likely than not that $58,500 of Non-U.S. NOLs, in jurisdictions other than the U.K., will not be utilized and have placed a VA against these NOLs. Accordingly, at December 31, 2016 , our net DTA associated with Non-U.S. NOLs was $31,600 . Excluding NOLs having an indefinite carryforward, principally in the U.K., the Non-U.S. NOLs will expire from 2017 to 2036 . At December 31, 2016 , we had U.S.-Federal NOLs of $1,567,400 . Of the U.S.-Federal NOLs, $413,100 were generated prior to 2014 and will expire in 2033 . The remaining $1,154,300 of U.S.-Federal NOLs were generated in 2015 as a result of the sale of our Nuclear Operations and will expire in 2035 . We believe it is more likely than not that all of the U.S.-Federal NOLs will be utilized. Accordingly, at December 31, 2016 , our DTA associated with U.S.-Federal NOLs was $548,600 . At December 31, 2016 , we had U.S.-State NOL DTAs of $193,100 . We believe it is more likely than not that $136,900 of the U.S.-State NOL DTAs will not be utilized and have placed a VA against these NOL DTAs. Accordingly, at December 31, 2016 , our net DTA associated with U.S.-State NOLs was $56,200 . The U.S.-State NOLs will expire from 2017 to 2036 . At December 31, 2016 , we had foreign tax credits and other tax credits of $27,400 and $29,900 , respectively. We believe it is more likely than not that the credits will be realized within the carryforward periods. These credits are subject to various expiration dates beginning in 2022. Unrecognized Income Tax Benefits —At December 31, 2016 and 2015 , our unrecognized income tax benefits totaled $14,162 and $9,140 , respectively, and we do not anticipate significant changes in this balance in the next twelve months. The following is a reconciliation of our unrecognized income tax benefits for the years ended December 31, 2016 and 2015 : Years Ended December 31, 2016 2015 Unrecognized income tax benefits at the beginning of the year $ 9,140 $ 13,458 Increase as a result of: Tax positions taken during the current period 6,038 1,313 Decreases as a result of: Lapse of applicable statute of limitations — (2,927 ) Settlements with taxing authorities (1,016 ) (2,704 ) Unrecognized income tax benefits at the end of the year (1) $ 14,162 $ 9,140 (1) If these income tax benefits were ultimately recognized, approximately $11,000 and $6,000 of the December 31, 2016 and 2015 balances, respectively, would benefit tax expense as we are contractually indemnified for the remaining balances. We have operations, and are subject to taxation, in various jurisdictions, including significant operations in the U.S., The Netherlands, Canada, the U.K., Australia, South America and the Middle East. Tax years remaining subject to examination by worldwide tax jurisdictions vary by country and legal entity, but are generally open for tax years ending after 2006 . To the extent penalties and associated interest are assessed on any underpayment of income tax, such amounts are accrued and classified as a component of income tax expense and interest expense, respectively. For 2016 , 2015 and 2014 , interest and penalties were not significant.

Contractors [Abstract]
UNAPPROVED CHANGE ORDERS, CLAIMS, INCENTIVES AND OTHER PROJECT MATTERS	UNAPPROVED CHANGE ORDERS, CLAIMS, INCENTIVES AND OTHER PROJECT MATTERS Unapproved Change Orders, Claims and Incentives —At December 31, 2016 and 2015 , we had unapproved change orders and claims included in project price totaling approximately $121,100 and $91,700 , respectively, for projects within our Engineering & Construction and Fabrication Services operating groups. At December 31, 2016 and 2015 , we also had incentives included in project price of approximately $43,000 and $91,500 , respectively, for projects in our Engineering & Construction and Fabrication Services operating groups. Of the aforementioned unapproved change orders, claims and incentives, approximately $141,100 had been recognized as revenue on a cumulative POC basis through December 31, 2016 . The aforementioned amounts recorded in project price reflect our best estimate of recovery amounts; however, the ultimate resolution and amounts received could differ from these estimates and could have a material adverse effect on our results of operations, financial position and cash flow. See Note 13 for further discussion of outstanding receivables related to one of our large cost-reimbursable projects. Other Project Matters —Backlog for each of our operating groups generally consists of several hundred contracts and our results may be impacted by changes in estimated project margins. For 2016 , significant changes in estimated margins on projects within our Engineering & Construction and Fabrication Services operating groups resulted in a decrease to our income from operations of approximately $328,000 , and significant changes in estimated margins on projects within our Engineering & Construction operating group resulted in an increase to our IFO of approximately $124,000 . For 2015 and 2014 , individual projects with significant changes in estimated margins did not have a material net impact on our income from operations. Two of the projects that resulted in a decrease to our IFO for 2016 were in a loss position at December 31, 2016 . One of the loss projects, within our Engineering & Construction operating group, was impacted primarily by lower than anticipated labor productivity and extensions of schedule during the second half of 2016 . At December 31, 2016 , the project was approximately 65% complete and had a reserve for estimated losses of approximately $49,000 . If future labor productivity differs from our current estimates, our schedule is further extended, or the project incurs schedule liquidated damages due to our inability to reach a favorable commercial resolution on such matters, the project may experience additional forecast cost increases. The other loss project, within our Fabrication Services operating group, was primarily impacted by lower than anticipated labor productivity. At December 31, 2016 , the project was approximately 75% complete and had a reserve for estimated losses of approximately $5,000 . If future labor productivity differs from our current estimates the project may experience additional forecast cost increases.

Segment Reporting [Abstract]
SEGMENT AND RELATED INFORMATION	SEGMENT AND RELATED INFORMATION Segment Information Our management structure and internal and public segment reporting are aligned based upon the services offered by our two operating groups, which represent our reportable segments: Engineering & Construction —Engineering & Construction provides EPC services for major energy infrastructure facilities. Fabrication Services —Fabrication Services provides fabrication and erection of steel plate structures; fabrication of piping systems and process modules; and manufacturing and distribution of pipe and fittings. Our chief operating decision maker evaluates the performance of these two operating groups based upon revenue and income from operations. Each operating group’s income from operations reflects corporate costs, allocated based primarily upon revenue. Intersegment revenue for our continuing operations is netted against the revenue of the segment receiving the intersegment services. For 2016 , 2015 and 2014 , intersegment revenue totaled approximately $233,900 , $312,300 and $374,300 , respectively. Intersegment revenue for the aforementioned periods primarily related to services provided by our Fabrication Services operating group to our Engineering & Construction operating group. As a result of the classification of our Capital Services Operations (which is primarily comprised of our former Capital Services reportable segment) and our Technology Operations (primarily comprised of our former Technology reportable segment and our Engineered Products Operations, representing a portion of our Fabrication Services reportable segment) as discontinued operations, the information for our remaining segments presented below has been recast to reflect: 1) a reallocation of certain corporate amounts previously allocated to the Capital Services segment, Technology segment and Fabrication Services segment that were not assignable to the discontinued operations, and 2) the portions of the previously reported Capital Services segment, Technology segment and Fabrication Services segment that are not included in the Capital Services Operations or Technology Operations, and 3) the portions of our remaining two segments that were included in the Capital Services Operations and Technology Operations. In addition, revenue for the remaining segments has been recast to reflect the intersegment revenue with our Capital Services Operations and Technology Operations that was previously eliminated prior to the discontinued operations classification (approximately $297,700 , $177,000 and $121,700 for 2016, 2015 and 2014, respectively). The following table presents total revenue, depreciation and amortization, equity earnings, income (loss) from continuing operations and capital expenditures by reportable segment for 2016 , 2015 , and 2014 : Years Ended December 31, 2016 2015 2014 Revenue Engineering & Construction $ 6,206,150 $ 7,827,633 $ 7,707,400 Fabrication Services 1,922,447 2,113,284 2,553,646 Total revenue $ 8,128,597 $ 9,940,917 $ 10,261,046 Depreciation And Amortization Engineering & Construction $ 18,602 $ 49,863 $ 63,928 Fabrication Services 53,034 54,697 59,138 Total depreciation and amortization $ 71,636 $ 104,560 $ 123,066 Equity Earnings (Loss) Engineering & Construction $ 7,222 $ (3,853 ) $ (1,297 ) Fabrication Services (1,486 ) (3,812 ) (77 ) Total equity earnings (loss) $ 5,736 $ (7,665 ) $ (1,374 ) Income (Loss) From Continuing Operations Engineering & Construction (1) $ 137,049 $ (892,671 ) $ 498,983 Fabrication Services 86,161 129,737 230,856 Total operating groups 223,210 (762,934 ) 729,839 Integration related costs — — (26,356 ) Total income (loss) from continuing operations $ 223,210 $ (762,934 ) $ 703,483 Capital Expenditures Engineering & Construction $ 4,476 $ 15,811 $ 46,798 Fabrication Services 32,542 42,541 49,479 Total capital expenditures $ 37,018 $ 58,352 $ 96,277 (1) As discussed further in Note 4 , during 2015 we recorded a non-cash pre-tax charge of approximately $1,505,900 within our Engineering & Construction operating group related to the sale of our Nuclear Operations. In addition, during 2016 we recorded a non-cash pre-tax charge of approximately $148,100 resulting from a reserve for the Transaction Receivable associated with the 2015 sale of our Nuclear Operations. The following table presents total assets of our continuing operations by reportable segment and discontinued operations for December 31, 2016, 2015 and 2014: December 31, 2016 2015 2014 Assets Engineering & Construction $ 3,738,303 $ 4,129,531 $ 4,651,080 Fabrication Services 2,114,637 2,295,523 1,997,414 Total assets of continuing operations 5,852,940 6,425,054 6,648,494 Assets of discontinued Technology Operations (Note 5) 1,109,604 1,151,384 1,076,585 Assets of discontinued Capital Services Operations (Note 5) 876,876 1,615,622 1,644,751 Total assets $ 7,839,420 $ 9,192,060 $ 9,369,830 Geographic Information The following table presents total revenue by country for those countries with revenue in excess of 10% of consolidated revenue during a given year based upon the location of the applicable projects: Years Ended December 31, 2016 2015 2014 Revenue by Country United States $ 5,478,820 $ 6,045,430 $ 4,433,397 Australia 1,744,055 2,168,737 2,495,185 Colombia 26,329 456,850 1,080,093 Other (1) 879,393 1,269,900 2,252,371 Total revenue $ 8,128,597 $ 9,940,917 $ 10,261,046 (1) Revenue earned in other countries, including The Netherlands (our country of domicile), was not individually greater than 10% of our consolidated revenue in 2016 , 2015 or 2014 . Our long-lived assets are primarily goodwill, other intangible assets and property and equipment. At December 31, 2016 , 2015 and 2014 , approximately 75% , 75% and 75% of property and equipment were located in the U.S., respectively, while our remaining assets were strategically located throughout the world. Our long-lived assets attributable to operations in The Netherlands were not significant at December 31, 2016 , 2015 or 2014 . Significant Customers For 2016 , 2015 and 2014 , revenue for a customer in our Engineering & Construction and Fabrication Services operating groups was approximately $1,136,000 (approximately 14% of consolidated 2016 revenue), approximately $1,647,000 (approximately 17% of consolidated 2015 revenue), and approximately $1,956,000 (approximately 19% of consolidated 2014 revenue), respectively. In addition, for 2016 , revenue for two other customers in our Engineering & Construction operating group were approximately $1,605,000 (approximately 20% of consolidated 2016 revenue) and approximately $1,099,000 (approximately 14% of consolidated 2016 revenue). In addition, for 2015 , revenue for another customer in our Engineering & Construction operating group was approximately $1,179,000 (approximately 12% of consolidated 2015 revenue). In addition, for 2014 , revenue for another customer in our Engineering & Construction operating group was approximately $1,081,000 (approximately 11% of consolidated 2014 revenue).

Subsequent Events [Abstract]
Subsequent Events	SUBSEQUENT EVENTS Discontinued Operations —On February 27, 2017, we entered into the CS Agreement with CSVC, under which CSVC agreed to acquire our Capital Services Operations (primarily comprised of our former Capital Services reportable segment). We completed the sale of the Capital Services Operations on June 30, 2017. We considered the Capital Services Operations to be a discontinued operation in the first quarter 2017, as the divestiture represented a strategic shift and would have a material effect on our operations and financial results. In the July 2017, we initiated a plan to market and sell our Technology Operations (primarily comprised of our former Technology reportable segment and our Engineered Products Operations, representing a portion of our Fabrication Services reportable segment). We considered the Technology Operations to be a discontinued operation in the third quarter 2017 as the anticipated divestiture represented a strategic shift and would have a material effect on our operations and financial results. Financial information and disclosures for all periods presented have been recast on a retrospective basis as if the discontinued operations criteria for the Capital Services Operations and Technology Operations were met as of December 31, 2016. See Note 2 and Note 5 for further discussion of our discontinued Capital Services Operations and Technology Operations. McDermott/CB&I Combination —On December 18, 2017, we entered into a business combination agreement (the “Combination Agreement”) with McDermott International, Inc. (“McDermott”) to combine in an all-stock transaction whereby McDermott stockholders will own approximately 53% of the combined company and our shareholders will own approximately 47% (the “Combination”). Under the terms of the agreement, our shareholders would be entitled to receive 2.47221 shares of McDermott common stock for each share of our common stock (or 0.82407 shares if McDermott effects a planned three-to-one reverse stock split prior to closing), together with cash in lieu of fractional shares and subject to any applicable withholding taxes. As a result of the Combination Agreement, we suspended our previous plan to market and sell our Technology Operations; however, the Technology Operations are reported as a discontinued operation for purposes of the recast Financial Statements and accompanying notes to the Financial Statements as the Combination Agreement was effected subsequent to the filing of our 2017 third quarter Form 10-Q and this recast information is being provided prior to the filing of our 2017 Form 10-K. Debt Compliance —On February 24, 2017, May 8, 2017 and August 9, 2017, we entered into amendments to our senior credit facilities which adjusted certain original and amended financial and restrictive covenants, introduced new financial and restrictive covenants, waived noncompliance with certain covenants and other defaults and events of default, and initially required the consummation of the sale of our Technology Operations. On December 18, 2017, we entered into further amendments to our senior credit facilities that suspended the requirement to consummate the sale of our Technology Operations and required us to complete the above described Combination by June 30, 2018 (the “Combination Closing Deadline”). We believe we will successfully achieve the various Combination transaction milestones required by our December 18, 2017 amendments, and believe it is probable we will complete the Combination by the Combination Closing Deadline. Prior to the anticipated Combination, our plan to maintain compliance with our covenants, satisfy our debt obligations, and continue as a going concern included the Technology Sale. However, our current plan is to complete the aforementioned Combination, with no further financing alternatives beyond the Combination. Absent this plan, we would be unable to satisfy our debt obligations, raising substantial doubt regarding our ability to continue as a going concern; however, the Combination alleviates the substantial doubt.

(4) In 2015 , we recorded a non-cash pre-tax charge of approximately $1,505,900 (approximately $1,135,200 after-tax) related to the impairment of goodwill (approximately $453,100 recorded in the third quarter) and intangible assets (approximately $79,100 recorded in the third quarter) and a loss on net assets sold (approximately $628,300 and $345,400 recorded in the third and fourth quarters, respectively).

SIGNIFICANT ACCOUNTING POLICI31

SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Basis of Accounting and Consolidation	The accompanying Consolidated Financial Statements (“Financial Statements”) have been prepared in accordance with the rules and regulations of the United States (“U.S.”) Securities and Exchange Commission (the “SEC”) and accounting principles generally accepted in the United States of America (“U.S. GAAP”).
Consolidation	These Financial Statements include all wholly-owned subsidiaries and those entities which we are required to consolidate. See the “Partnering Arrangements” section of this footnote for further discussion of our consolidation policy for those entities that are not wholly-owned. Intercompany balances and transactions are eliminated in consolidation. Certain balances at December 31, 2015 have been reclassified within our Consolidated Balance Sheet (“Balance Sheet”) to conform to our December 31, 2016 presentation.
Discontinued Operations	On February 27, 2017, we entered into a definitive agreement (the “CS Agreement”) with CSVC Acquisition Corp (“CSVC”), under which CSVC agreed to acquire our “Capital Services Operations” (primarily comprised of our former Capital Services reportable segment). Our Capital Services Operations provided comprehensive and integrated maintenance services, environmental engineering and remediation, construction services, program management, and disaster response and recovery services for private-sector customers and governments. We completed the sale of the Capital Services Operations on June 30, 2017 (the “Closing Date”), as described in Note 5 . We considered the Capital Services Operations to be a discontinued operation in the first quarter 2017, as the divestiture represented a strategic shift and would have a material effect on our operations and financial results.
Use of Estimates	Use of Estimates —The preparation of our Financial Statements in conformity with U.S. GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses and related disclosures of contingent assets and liabilities. We believe the most significant estimates and judgments are associated with revenue recognition for our contracts, including estimating costs and the recognition of incentive fees and unapproved change orders and claims; fair value and recoverability assessments that must be periodically performed with respect to long-lived tangible assets, goodwill and other intangible assets; valuation of deferred tax assets and financial instruments; the determination of liabilities related to self-insurance programs and income taxes; and consolidation determinations with respect to our partnering arrangements. If the underlying estimates and assumptions upon which our Financial Statements are based change in the future, actual amounts may differ from those included in the accompanying Financial Statements.
Revenue Recognition	Revenue Recognition —Our revenue is primarily derived from long-term contracts and is generally recognized using the percentage of completion (“POC”) method, primarily based on the percentage that actual costs-to-date bear to total estimated costs to complete each contract. We follow the guidance of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Revenue Recognition Topic 605-35 for accounting policies relating to our use of the POC method, estimating costs, and revenue recognition, including the recognition of incentive fees, unapproved change orders and claims, and combining and segmenting contracts. We primarily utilize the cost-to-cost approach to estimate POC as we believe this method is less subjective than relying on assessments of physical progress. Under the cost-to-cost approach, the use of estimated costs to complete each contract is a significant variable in the process of determining recognized revenue and is a significant factor in the accounting for contracts. Significant estimates that impact the cost to complete each contract are costs of engineering, materials, components, equipment, labor and subcontracts; labor productivity; schedule durations, including subcontractor or supplier progress; liquidated damages; contract disputes, including claims; achievement of contractual performance requirements; and contingency, among others. The cumulative impact of revisions in total cost estimates during the progress of work is reflected in the period in which these changes become known, including, to the extent required, the reversal of profit recognized in prior periods and the recognition of losses expected to be incurred on contracts in progress. Due to the various estimates inherent in our contract accounting, actual results could differ from those estimates. See Note 17 for discussion of projects with significant changes in estimated margins during 2016, 2015 and 2014. Our long-term contracts are awarded on a competitively bid and negotiated basis and the timing of revenue recognition may be impacted by the terms of such contracts. We use a range of contracting options, including cost-reimbursable, fixed-price and hybrid, which has both cost-reimbursable and fixed-price characteristics. Fixed-price contracts, and hybrid contracts with a more significant fixed-price component, tend to provide us with greater control over project schedule and the timing of when work is performed and costs are incurred, and accordingly, when revenue is recognized. Cost-reimbursable contracts, and hybrid contracts with a more significant cost-reimbursable component, generally provide our customers with greater influence over the timing of when we perform our work, and accordingly, such contracts often result in less predictability with respect to the timing of revenue recognition. Contract revenue for our long-term contracts recognized under the POC method reflects the original contract price adjusted for approved change orders and estimated recoveries for incentive fees, unapproved change orders and claims. We recognize revenue associated with incentive fees when the value can be reliably estimated and recovery is probable. We recognize revenue associated with unapproved change orders and claims to the extent the related costs have been incurred, the value can be reliably estimated and recovery is probable. Our recorded incentive fees, unapproved change orders and claims reflect our best estimates of recovery amounts; however, the ultimate resolution and amounts received could differ from these estimates. See Note 17 for additional discussion of our recorded unapproved change orders, claims and incentives. With respect to our engineering, procurement, and construction (“EPC”) services, our contracts are not segmented between types of services, such as engineering and construction, if each of the EPC components is negotiated concurrently or if the pricing of any such services is subject to the ultimate negotiation and agreement of the entire EPC contract. However, an EPC contract including technology or fabrication services may be segmented if we satisfy the segmenting criteria in ASC 605-35. Revenue recorded in these situations is based on our prices and terms for similar services to third party customers. Segmenting a contract may result in different interim rates of profitability for each scope of service than if we had recognized revenue without segmenting. In some instances, we may combine contracts that are entered into in multiple phases, but are interdependent and include pricing considerations by us and the customer that are impacted by all phases of the project. Otherwise, if each phase is independent of the other and pricing considerations do not give effect to another phase, the contracts will not be combined. Cost of revenue for our long-term contracts includes direct contract costs, such as materials and labor, and indirect costs that are attributable to contract activity. The timing of when we bill our customers is generally dependent upon advance billing terms, milestone billings based on the completion of certain phases of the work, or when services are provided. Projects with costs and estimated earnings recognized to date in excess of cumulative billings are reported on the Balance Sheets as costs and estimated earnings in excess of billings. Projects with cumulative billings in excess of costs and estimated earnings recognized to date are reported on the Balance Sheets as billings in excess of costs and estimated earnings.
Receivables	Any uncollected billed amounts, including contract retentions, are reported as accounts receivable. At December 31, 2016 and 2015 , accounts receivable included contract retentions of approximately $72,100 and $55,400 , respectively. Contract retentions due beyond one year were approximately $37,500 at December 31, 2016 . Revenue for our service contracts that do not satisfy the criteria for revenue recognition under the POC method is recorded at the time services are performed. Revenue associated with incentive fees for these contracts is recognized when earned. Unbilled receivables for our service contracts are recorded within accounts receivable and were not material at December 31, 2016 and 2015 . Revenue for our pipe and steel fabrication and catalyst manufacturing contracts that are independent of an EPC contract, or for which we satisfy the segmentation criteria discussed above, is recognized upon shipment of the fabricated or manufactured units. During the fabrication or manufacturing process, all related direct and allocable indirect costs are capitalized as work in process inventory and such costs are recorded as cost of revenue at the time of shipment. Our billed and unbilled revenue may be exposed to potential credit risk if our customers should encounter financial difficulties, and we maintain reserves for specifically-identified potential uncollectible receivables. At December 31, 2016 and 2015 , our allowances for doubtful accounts were not material.
Precontract Costs	Precontract Costs —Precontract costs are generally charged to cost of revenue as incurred, but, in certain cases their recognition may be deferred if specific probability criteria are met. We had no significant deferred precontract costs at December 31, 2016 or 2015 .
Research and Development	Research and Development —Expenditures for research and development activities are charged to cost of revenue as incurred and were $4,699 , $4,607 and $3,629 for 2016 , 2015 and 2014 , respectively.
Other Operating Expense (Income), Net	Other Operating Expense (Income), Net — Other operating expense (income), net , generally represents (gains) losses associated with the sale or disposition of property and equipment. For 2015, other operating expense (income), net also included a foreign exchange loss of approximately $11,000 associated with the re-measurement of certain non-U.S. Dollar denominated net assets.
Integration Related Costs	Integration Related Costs —Integration related costs were $26,356 for 2014, and primarily related to facility consolidations, including the associated accrued future lease costs for vacated facilities and unutilized capacity, personnel relocation and severance related costs, and systems integration costs.
Depreciation Expense	Depreciation Expense —Property and equipment are recorded at cost and depreciated on a straight-line basis over their estimated useful lives, including buildings and improvements ( 10 to 40 years) and plant and field equipment ( 1 to 15 years). Renewals and betterments that substantially extend the useful life of an asset are capitalized and depreciated. Leasehold improvements are depreciated over the lesser of the useful life of the asset or the applicable lease term. Depreciation expense is primarily included within cost of revenue and was $63,830 , $84,939 and $96,209 for 2016 , 2015 and 2014 , respectively. See Note 9 for disclosure of the components of property and equipment.
Recoverability of Goodwill and Recoverability of Other Long-Lived Assets	Recoverability of Goodwill —Goodwill is not amortized to earnings, but instead is reviewed for impairment at least annually at a reporting unit level, absent any indicators of impairment or when other actions require an impairment assessment (such as a change in reporting units). We perform our annual impairment assessment during the fourth quarter of each year based upon balances as of October 1. We identify a potential impairment by comparing the fair value of the applicable reporting unit to its net book value, including goodwill. If the net book value exceeds the fair value of the reporting unit, an indication of potential impairment exists, and we measure the impairment by comparing the carrying value of the reporting unit’s goodwill to its implied fair value. To determine the fair value of our reporting units and test for impairment, we utilize an income approach (discounted cash flow method) as we believe this is the most direct approach to incorporate the specific economic attributes and risk profiles of our reporting units into our valuation model. This is consistent with the methodology used to determine the fair value of our reporting units in previous years. We generally do not utilize a market approach given the lack of relevant information generated by market transactions involving comparable businesses. However, to the extent market indicators of fair value become available, we consider such market indicators in our discounted cash flow analysis and determination of fair value. See Note 7 for additional discussion of our goodwill and related goodwill impairment recorded during 2016. Recoverability of Other Long-Lived Assets —We amortize our finite-lived intangible assets on a straight-line basis with lives ranging from 6 to 20 years, absent any indicators of impairment. We review tangible assets and finite-lived intangible assets for impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable. If a recoverability assessment is required, the estimated future cash flow associated with the asset or asset group will be compared to the asset’s carrying amount to determine if an impairment exists. See Note 7 for additional discussion of our intangible assets.
Earnings Per Share ("EPS")	Earnings Per Share (“EPS”)— Basic EPS is calculated by dividing net income attributable to CB&I by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the assumed conversion of dilutive securities, consisting of restricted shares, performance based shares (where performance criteria have been met), stock options and directors’ deferred-fee shares. See Note 3 for calculations associated with basic and diluted EPS.
Cash Equivalents	Cash Equivalents —Cash equivalents are considered to be highly liquid securities with original maturities of three months or less.
Inventory	Inventory —Inventory is recorded at the lower of cost or market and cost is determined using the first-in-first-out or weighted-average cost method. The cost of inventory includes acquisition costs, production or conversion costs, and other costs incurred to bring the inventory to a current location and condition. An allowance for excess or inactive inventory is recorded based upon an analysis that considers current inventory levels, historical usage patterns, estimates of future sales expectations and salvage value. See Note 6 for additional discussion of our inventory.
Foreign Currency	Foreign Currency —The nature of our business activities involves the management of various financial and market risks, including those related to changes in foreign currency exchange rates. The effects of translating financial statements of foreign operations into our reporting currency are recognized as a cumulative translation adjustment in accumulated other comprehensive income (loss) (“AOCI”) which is net of tax, where applicable. With the exception of a foreign exchange loss of approximately $11,000 included within other operating expense (income), net related to the re-measurement of certain non-U.S. Dollar denominated net assets during 2015, foreign currency transactional and re-measurement exchange gains (losses) are included within cost of revenue and were not material in 2016 , 2015 and 2014 .
Financial Instruments	Financial Instruments —We utilize derivative instruments in certain circumstances to mitigate the effects of changes in foreign currency exchange rates and interest rates, as described below: • Foreign Currency Exchange Rate Derivatives —We do not engage in currency speculation; however, we utilize foreign currency exchange rate derivatives on an ongoing basis to hedge against certain foreign currency related operating exposures. We generally seek hedge accounting treatment for contracts used to hedge operating exposures and designate them as cash flow hedges. Therefore, gains and losses, exclusive of credit risk and forward points (which represent the time value component of the fair value of our derivative positions), are included in AOCI until the associated underlying operating exposure impacts our earnings. Changes in the fair value of (1) credit risk and forward points, (2) instruments deemed ineffective during the period, and (3) instruments that we do not designate as cash flow hedges are recognized within cost of revenue. • Interest Rate Derivatives —At December 31, 2016 , we continued to utilize a swap arrangement to hedge against interest rate variability associated with $290,375 of our outstanding $300,000 unsecured term loan (the “Term Loan”). The swap arrangement has been designated as a cash flow hedge as its critical terms matched those of the Term Loan at inception and through December 31, 2016 . Accordingly, changes in the fair value of the swap arrangement are included in AOCI until the associated underlying exposure impacts our earnings. For those contracts designated as cash flow hedges, we document all relationships between the derivative instruments and associated hedged items, as well as our risk-management objectives and strategy for undertaking hedge transactions. This process includes linking all derivatives to specific firm commitments or highly-probable forecasted transactions. We continually assess, at inception and on an ongoing basis, the effectiveness of derivative instruments in offsetting changes in the cash flow of the designated hedged items. Hedge accounting designation is discontinued when (1) it is determined that the derivative is no longer highly effective in offsetting changes in the cash flow of the hedged item, including firm commitments or forecasted transactions, (2) the derivative is sold, terminated, exercised, or expires, (3) it is no longer probable that the forecasted transaction will occur, or (4) we determine that designating the derivative as a hedging instrument is no longer appropriate.
Income Taxes	Income Taxes —Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis using currently enacted income tax rates for the years in which the differences are expected to reverse. A valuation allowance is provided to offset any net deferred tax assets (“DTA(s)”) if, based upon the available evidence, it is more likely than not that some or all of the DTAs will not be realized. The realization of our net DTAs depends upon our ability to generate sufficient future taxable income of the appropriate character and in the appropriate jurisdictions. Income tax and associated interest and penalty reserves, where applicable, are recorded in those instances where we consider it more likely than not that additional tax will be due in excess of amounts reflected in income tax returns filed worldwide, irrespective of whether or not we have received tax assessments. We continually review our exposure to additional income tax obligations and, as further information is known or events occur, changes in our tax and interest reserves may be recorded within income tax expense and interest expense, respectively.
Partnering Arrangements	Partnering Arrangements — In the ordinary course of business, we execute specific projects and conduct certain operations through joint venture, consortium and other collaborative arrangements (collectively referred to as “venture(s)”). We have various ownership interests in these ventures, with such ownership typically proportionate to our decision making and distribution rights. The ventures generally contract directly with the third party customer; however, services may be performed directly by the ventures, or may be performed by us, our partners, or a combination thereof. Venture net assets consist primarily of working capital and property and equipment, and assets may be restricted from being used to fund obligations outside of the venture. These ventures typically have limited third party debt or have debt that is non-recourse in nature; however, they may provide for capital calls to fund operations or require participants in the venture to provide additional financial support, including advance payment or retention letters of credit. Each venture is assessed at inception and on an ongoing basis as to whether it qualifies as a VIE under the consolidations guidance in ASC 810. A venture generally qualifies as a VIE when it (1) meets the definition of a legal entity, (2) absorbs the operational risk of the projects being executed, creating a variable interest, and (3) lacks sufficient capital investment from the partners, potentially resulting in the venture requiring additional subordinated financial support, if necessary, to finance its future activities. If at any time a venture qualifies as a VIE, we perform a qualitative assessment to determine whether we are the primary beneficiary of the VIE and, therefore, need to consolidate the VIE. We are the primary beneficiary if we have (1) the power to direct the economically significant activities of the VIE and (2) the right to receive benefits from, and obligation to absorb losses of, the VIE. If the venture is a VIE and we are the primary beneficiary, or we otherwise have the ability to control the venture, we consolidate the venture. If we are not determined to be the primary beneficiary of the VIE, or only have the ability to significantly influence, rather than control the venture, we do not consolidate the venture. We account for unconsolidated ventures using either proportionate consolidation for both the Balance Sheet and Statement of Operations, when we meet the applicable accounting criteria to do so, or the equity method.
New Accounting Standards	New Accounting Standards —In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, which provides a single comprehensive accounting standard for revenue recognition for contracts with customers and supersedes current industry-specific guidance, including ASC 605-35. The new standard prescribes a five-step revenue recognition model that focuses on transfer of control and entitlement to payment when determining the amount of revenue to be recognized. The new model requires companies to identify contractual performance obligations and determine whether revenue should be recognized at a point in time or over time for each of these obligations. These concepts, as well as other aspects of the ASU, may change the method and/or timing of revenue recognition for certain of our contracts, primarily associated with our fabrication and manufacturing contracts. We expect that revenue generated from our EPC and engineering services contracts will continue to be recognized over time utilizing the cost-to-cost measure of progress consistent with current practice. We also expect our revenue recognition disclosures to significantly expand due to the new qualitative and quantitative requirements regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from our contracts. We will adopt the standard, including any updates to the standard, upon its effective date in the first quarter 2018 utilizing the modified retrospective approach. This approach will result in a cumulative adjustment to beginning equity in the first quarter 2018 for contracts impacted by the adoption of the standard. We are continuing to assess the potential impact of the new standard on our Financial Statements. In February 2016, the FASB issued ASU 2016-02, which requires the recognition of a right-of-use asset and a lease liability for most lease arrangements with a term greater than one year, and increases qualitative and quantitative disclosures regarding leasing transactions. The standard is effective for us in the first quarter 2019, although early adoption is permitted. Transition requires application of the new guidance at the beginning of the earliest comparative balance sheet period presented utilizing a modified retrospective approach. We are assessing the timing of adoption of the new standard and its potential impact on our Financial Statements. In March 2016, the FASB issued ASU 2016-09, which modifies the accounting for excess tax benefits and tax deficiencies associated with share-based payments, and amends the associated cash flow presentation. ASU 2016-09 eliminates the requirement to recognize excess tax benefits in additional paid-in capital (“APIC”), and the requirement to evaluate tax deficiencies for APIC or income tax expense classification, and provides for these benefits or deficiencies to be recorded as an income tax expense or benefit in the income statement. Additionally, tax benefits of dividends on share-based payment awards will also be reflected as an income tax expense or benefit in the income statement. With these changes, tax-related cash flows resulting from share-based payments will be classified as operating activities as opposed to financing, as currently presented. We will adopt the standard upon its effective date in the first quarter 2017 and do not believe it will have a material impact on our Financial Statements. In the first quarter 2016, we adopted ASU 2015-02, which amends existing consolidation requirements in ASC 810 associated with: (1) determining the consolidation model and assessing control for limited partnerships and similar entities; (2) determining when fees paid to decision makers or service providers are variable interests; and (3) evaluating interests held by de facto agents or related parties of the reporting entity. Our adoption did not have a material impact on our Financial Statements. In the first quarter 2016, we adopted ASU 2015-03, which requires presentation of debt issuance costs as a direct deduction from the related debt liability rather than as an asset, as presented under previous guidance. Our adoption resulted in the reclassification of deferred debt issuance costs from other current assets and other non-current assets of approximately $2,129 and $8,168 , respectively, to current maturities of long-term debt and long-term debt, respectively, in our December 31, 2015 Balance Sheet.

[2]	Our venture arrangements allow for excess working capital of the ventures to be advanced to the venture partners. Such advances are returned to the ventures for working capital needs as necessary. Accordingly, at a reporting period end a venture may have advances to its partners which are reflected as an advance receivable within current assets of the venture. As summarized in Note 9, at December 31, 2016 and 2015, other current assets on the Balance Sheets included approximately $374,800 and $325,000, respectively, related to our proportionate share of advances from the ventures to our venture partners, and other current liabilities included approximately $394,400 and $334,900, respectively, related to advances to CB&I from the ventures.

[1]	The actuarial pension plan loss for 2016 was primarily associated with a decrease in discount rate assumptions for our pension plans. The actuarial pension plan gain for 2015 was primarily associated with an increase in the discount rate assumptions for our pension plans. The actuarial other postretirement plan gain for 2015 was primarily associated with an increase in the discount rate assumptions and a decrease in the percent of retiring employees electing medical coverage for our other postretirement plan.
[2]	The currency translation loss for 2016 and 2015 was primarily associated with the strengthening of the U.S. Dollar against the currencies associated with our international pension plans, primarily the Euro and British Pound.
[3]	During 2017, we expect to contribute approximately $15,900 and $2,500 to our pension and other postretirement plans, respectively.
[4]	During 2017, we expect to recognize approximately $(600) and $4,700 of previously unrecognized net prior service pension credits and net actuarial pension losses, respectively.

[1]	Our 2016 contributions as a percentage of total plan contributions were not available for any of our plans. For 2015 and 2014, our contributions to the Utah Pipe Trades Pension Trust Fund, the Twin City Carpenters and Joiners Pension Fund, the Twin City Ironworkers Pension Plan, the Southern Ironworkers Pension Fund, the Plumbers and Steamfitters Local 150 Pension Fund and the Boilermakers’ National Pension Plan (Canada) each exceeded 5% of total plan contributions. The level of our contributions to each plan noted above varies from period to period based upon the level of work being performed that is covered under the applicable collective-bargaining agreement.
[2]	Pension Protection Act Zone Status and FIP/RP plans are applicable to our U.S.-registered plans only, as these terms are not defined within Canadian pension legislation. In the U.S., plans funded less than 65% are in the red zone, plans funded at least 65%, but less than 80% are in the yellow zone, and plans funded at least 80% are in the green zone. The requirement for FIP or RP plans in the U.S. is based on the funding level or zone status of the applicable plan.
[3]	The contributions in 2015 and 2014 were associated with plans that were included with our former Nuclear Operations, which were sold on December 31, 2015.
[4]	Our remaining contributions are to various U.S. and Canadian plans, which are individually immaterial.
