Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND NATURE OF OPERATIONS	ORGANIZATION AND NATURE OF OPERATIONS Organization and Nature of Operations — Founded in 1889 , Chicago Bridge & Iron Company N.V. (“CB&I” or the “Company”) provides a wide range of services, including conceptual design, technology, engineering, procurement, fabrication, modularization, construction, commissioning, maintenance, program management and environmental services to customers in the energy infrastructure market throughout the world, and is a provider of diversified government services. Our business is aligned into four operating groups, which represent our reportable segments. During the first quarter 2015, we realigned our four operating groups to reflect the present management oversight of our operations: (1) Engineering & Construction (formerly Engineering, Construction & Maintenance); (2) Fabrication Services; (3) Technology; and (4) Capital Services (formerly Environmental Solutions). Natural gas, petroleum, power and petrochemical projects for the worldwide energy and natural resource industries accounted for a majority of our revenue in 2015 , 2014 and 2013 . See Note 19 for a discussion of our realigned operating groups and related financial information.

Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Basis of Accounting and Consolidation —The accompanying Consolidated Financial Statements (“Financial Statements”) are 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”). 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. Significant intercompany balances and transactions are eliminated in consolidation. 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. 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 2015 , 2014 , and 2013 , individual projects with significant changes in estimated margins did not have a material net impact on our income from operations. 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 estimate of recovery amounts; however, the ultimate resolution and amounts received could differ from these estimates. See Note 18 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 is reported on the Consolidated Balance Sheet (“Balance Sheet”) as costs and estimated earnings in excess of billings. Projects with cumulative billings in excess of costs and estimated earnings recognized to date is reported on the Balance Sheet as billings in excess of costs and estimated earnings. The net balances on our Balance Sheet are collectively referred to as Contracts in Progress, net, and the components of these balances at December 31, 2015 and December 31, 2014 were as follows: December 31, 2015 December 31, 2014 Asset (1) Liability (1) Asset Liability Costs and estimated earnings on contracts in progress $ 14,853,683 $ 21,942,765 $ 20,119,444 $ 26,052,767 Billings on contracts in progress (14,165,369 ) (23,867,971 ) (19,344,800 ) (27,479,495 ) Margin fair value liability for acquired contracts (2) — (8,905 ) — (558,760 ) Contracts in Progress, net $ 688,314 $ (1,934,111 ) $ 774,644 $ (1,985,488 ) (1) The Contracts in Progress, net asset and liability balances reflect a decrease of approximately $1,443,100 and $468,500 (including approximately $432,000 of margin fair value liability), respectively, as a result of the sale of our Nuclear Operations, discussed further in Note 5 . (2) The balance represents a margin fair value liability associated with long-term contracts acquired in connection with our acquisition of The Shaw Group Inc. (“Shaw”) (the “Shaw Acquisition” or the “Acquisition”) on February 13, 2013 (the “Acquisition Closing Date”). The margin fair value liability was approximately $ 745,500 at the Acquisition Closing Date and is recognized as revenue on a POC basis as the applicable projects progress. Revenue and the related income from operations recognized during 2015 and 2014 was approximately $117,800 and $115,900 , respectively. Any uncollected billed amounts, including contract retentions, are reported as accounts receivable. At December 31, 2015 and 2014 , accounts receivable included contract retentions of approximately $62,900 and $53,000 , respectively. Contract retentions due beyond one year were not material at December 31, 2015 or 2014 . 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 approximately $71,600 and $66,900 at December 31, 2015 and 2014 , respectively. 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, 2015 and 2014 , 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, 2015 or 2014 . Research and Development —Expenditures for research and development activities are charged to cost of revenue as incurred and were $28,301 , $28,432 and $27,071 for 2015 , 2014 and 2013 , 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 gain of approximately $7,500 related to the contribution of a technology to our unconsolidated Chevron-Lummus Global (“CLG”) joint venture and a foreign exchange loss of approximately $11,000 associated with the re-measurement of certain non-U.S. Dollar denominated net assets. Acquisition and Integration Related Costs —Acquisition and integration related costs were $39,685 and $95,737 for 2014 and 2013, respectively. For 2014 and 2013, integration related costs 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. For 2013, acquisition related costs primarily related to transaction costs, professional fees, and change-in-control and severance related costs associated with the Shaw Acquisition. 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 $103,510 , $114,892 and $118,915 for 2015 , 2014 and 2013 , 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. See Note 7 for additional discussion of our goodwill and related goodwill impairment recorded during 2015 . Recoverability of Other Long-Lived Assets —We amortize our finite-lived intangible assets on a straight-line basis with lives ranging from 3 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 and related impairment recorded during 2015 . 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 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 disclosures associated with 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 2015 , 2014 and 2013 . 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, 2015 , we continued to utilize a swap arrangement to hedge against interest rate variability associated with $366,125 of our outstanding $450,000 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, 2015 . 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 12 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 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 17 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 proportionate consolidation for both our Balance Sheet and Statement of Operations when we meet the applicable accounting criteria to do so and utilize the equity method otherwise. 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. In August 2015, the FASB issued ASU 2015-14, which delays the effective date of ASU 2014-09 by one year while allowing for early adoption as of the original effective date. CB&I will adopt the standard beginning in the first quarter 2018 in accordance with the provisions of ASU 2015-14. The new standard prescribes a five-step revenue recognition model that focuses on transfer of control and entitlement to consideration in determining the amount of revenue to be recognized. The guidance also significantly expands qualitative and quantitative disclosure requirements regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Our adoption of ASU 2014-09 will result in retrospective application, either in the form of recasting all prior periods presented or a cumulative adjustment to equity in the period of adoption. We are assessing the impact that the new standard will have on our Financial Statements. In February 2015, the FASB issued ASU 2015-02, which amends existing consolidation requirements in ASC 810 and will require entities to evaluate their consolidation analysis for subsidiaries that are not wholly-owned. ASU 2015-02 includes amended guidance 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. ASU 2015-02 is effective for us beginning in the first quarter 2016. We do not expect the adoption of ASU 2015-02 to have a material impact on our consolidated financial position, results of operations, or cash flows. In April 2015, the FASB issued ASU 2015-03, which changes the presentation of debt issuance costs. Upon adoption, debt issuance costs would be presented as a direct deduction from the related debt liability rather than as an asset, as currently presented. ASU 2015-03 is effective for us beginning in the first quarter 2016. We do not expect the adoption of ASU 2015-03 to have a material impact on our consolidated financial position, results of operations, or cash flows. In November 2015, the FASB issued ASU 2015-17, which requires deferred tax assets and deferred tax liabilities to be presented as non-current, rather than separately presented as current and non-current, on the balance sheet. ASU 2015-17 is effective for us beginning in the first quarter 2017; however, as permitted, we early adopted ASU 2015-17 effective October 1, 2015. We chose to apply the standard prospectively with our December 31, 2015 deferred taxes presented as non-current on our Balance Sheet. The December 31, 2014 presentation of deferred taxes was not retrospectively adjusted.

Business Combinations [Abstract]
ACQUISITIONS	ACQUISITIONS Shaw Acquisition General —As more fully described in our 2013 Annual Report on Form 10-K, on the Acquisition Closing Date, we acquired Shaw for a gross purchase price of $3,340,070 , comprised of $2,851,260 in cash consideration and $488,810 in equity consideration. The cash consideration was funded using $1,051,260 from existing cash balances of CB&I and Shaw on the Acquisition Closing Date, and the remainder was funded using debt financing. Shaw’s unrestricted cash balance on the Acquisition Closing Date totaled $1,137,927 , and accordingly, the cash portion of our purchase price, net of cash acquired, was $1,713,333 and our total purchase price, net of cash acquired, was $2,202,143 . The results from the Shaw Acquisition were incorporated within our expanded operating groups beginning on the Acquisition Closing Date. Supplemental Pro Forma Information —The following pro forma condensed combined financial information (“the pro forma financial information”) presented for 2013 gives effect to the Shaw Acquisition, accounted for as a business combination using the purchase method of accounting. The pro forma financial information gives effect to pro forma events that are directly attributable to the Acquisition, factually supportable, and expected to have a continuing impact on the combined results of CB&I and Shaw following the Acquisition. The pro forma financial information includes adjustments to: (1) exclude transaction costs, professional fees, and change-in-control and severance-related costs that were included in CB&I's and Shaw’s historical results and are not expected to be recurring; (2) exclude the results of portions of the Shaw business that were not acquired by CB&I or are not expected to have a continuing impact; (3) include additional intangibles amortization and net interest expense associated with the Shaw Acquisition; and (4) include the pro forma results of Shaw from January 1, 2013 through the Acquisition Closing Date. Adjustments, net of tax, included in the pro forma net income below that were of a non-recurring nature totaled approximately $73,300 , reflecting the elimination of financing and acquisition and integration related costs. This pro forma financial information has been presented for illustrative purposes only and is not necessarily indicative of the operating results that would have been achieved had the pro forma events taken place on the dates indicated. Further, the pro forma financial information does not purport to project the future operating results of the combined company following the Acquisition. Year Ended December 31, 2013 Pro forma revenue $ 11,583,997 Pro forma net income attributable to CB&I $ 529,942 Pro forma net income attributable to CB&I per share: Basic $ 4.95 Diluted $ 4.88 Other Acquisitions On May 17, 2013, we acquired a coal gasification technology (“E-Gas”) for cash consideration of approximately $60,800 . The E-Gas acquisition primarily consisted of process technology intangible assets that have an estimated life of 15 years and are amortized on a straight-line basis. The impact of the acquisition was not material to our results and therefore, pro forma information has not been presented. We had no acquisitions in 2015 or 2014.

DISPOSITION OF NUCLEAR OPERATIO

Discontinued Operations and Disposal Groups [Abstract]
DISPOSITION OF NUCLEAR OPERATIONS	DISPOSITION OF NUCLEAR OPERATIONS Transaction Summary —On October 27, 2015 , we entered into an agreement (the “Agreement”) with Westinghouse Electric Company LLC (“WEC”) pursuant to which WEC acquired our nuclear power construction business, including the Nuclear Projects discussed further in Note 18 (collectively, “Nuclear Operations”). On December 31, 2015 , we completed the sale for estimated transaction consideration of approximately $161,000 , which will be received upon WEC’s substantial completion of the Nuclear Projects. The present value of the estimated consideration is approximately $143,000 (the “Estimated Sales Proceeds”) and is recorded within other non-current assets on our December 31, 2015 Balance Sheet. In addition, our Fabrication Services operating group will continue to supply discrete scopes of modules, fabricated pipe and specialty services to WEC (“Ongoing WEC Projects”) related to the Nuclear Projects. As part of the Agreement, we agreed not to pursue existing change orders and claims against WEC for certain Ongoing WEC Projects and we agreed to receive certain milestone based payments of up to $68,000 for the Ongoing WEC Projects. The net impact of foregoing the pursuit of change orders and claims and accepting the milestone based payments on the Ongoing WEC Projects was not material. Our Nuclear Operations were included within our Engineering & Construction operating group. As a result of the Agreement and sale, during 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). The net tax benefit (approximately $370,700 ) on the charge reflects the non-deductibility of the goodwill impairment. The third quarter impairments and loss totaling approximately $1,160,500 (approximately $904,200 after-tax) were recorded in connection with the classification of the assets and liabilities of the Nuclear Operations as held for sale on our September 30, 2105 Balance Sheet, as we believed the completion of the sale was probable. The incremental loss on net assets sold of approximately $345,400 ( $231,000 after-tax) during the fourth quarter was due to changes in working capital on the Nuclear Projects during the quarter and revisions to the assets and liabilities sold. Disposition Related Charges —A summary of the pre-tax charge for 2015 related to the sale of our Nuclear Operations is as follows: Year Ended December 31, 2015 Loss on net assets sold (see below) $ 973,651 Intangible assets impairment (Note 7) 79,100 Loss on net assets sold and intangible assets impairment 1,052,751 Goodwill impairment (Note 7) 453,100 Total pre-tax charge $ 1,505,851 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. See Note 7 for additional discussion of our goodwill and intangible assets impairment charges. Loss on Net Assets Sold —The assets and liabilities sold on December 31, 2015 are summarized as follows: Assets Accounts receivable $ 188,858 Costs and estimated earnings in excess of billings 1,443,121 Property and equipment, net 132,191 Other assets 12,321 Assets sold $ 1,776,491 Liabilities Margin fair value liability (Note 2) $ 432,036 Billings in excess of costs and estimated earnings 36,524 Accounts payable 200,633 Other liabilities 2,647 Liabilities sold $ 671,840 Net assets sold $ 1,104,651 Estimated Sales Proceeds (net of transaction costs of $12,000) 131,000 Loss on net assets sold $ 973,651 Results of Nuclear Operations —The revenue and pre-tax income of our Nuclear Operations for 2015 , 2014 and 2013 was as follows: Years Ended December 31, 2015 2014 2013 Revenue $ 2,061,167 $ 1,841,018 $ 1,007,838 Pre-tax income $ 215,150 $ 151,800 $ 61,200

The change in goodwill by reporting segment for 2015 and 2014 was as follows: Engineering & Construction (1) Fabrication Services (1) Technology (1) Capital Services (1) Total Balance at December 31, 2013 $ 2,367,930 $ 668,825 $ 305,106 $ 884,607 $ 4,226,468 Amortization of tax goodwill in excess of book goodwill 953 (636 ) (1,917 ) — (1,600 ) Foreign currency translation and other (29,637 ) — — — (29,637 ) Balance at December 31, 2014 $ 2,339,246 $ 668,189 $ 303,189 $ 884,607 $ 4,195,231 Impairment charges (described below) (2) (453,100 ) — — — (453,100 ) Amortization of tax goodwill in excess of book goodwill (3,789 ) (1,592 ) (3,068 ) — (8,449 ) Foreign currency translation and other (22,176 ) — — — (22,176 ) Balance at December 31, 2015 $ 1,860,181 $ 666,597 $ 300,121 $ 884,607 $ 3,711,506 (1) As discussed below, during 2015 we realigned our four operating groups to reflect the present management oversight of our operations, which resulted in the movement of goodwill between operating groups. Accordingly, the goodwill balances at December 31, 2014 and 2013 were reclassified to conform to the 2015 presentation. (2) At December 31, 2015, we had $453,100 in accumulated impairment losses. 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 December 31, 2014, we had the following seven reporting units within our four operating groups: • Engineering, Construction & Maintenance —Our Engineering, Construction & Maintenance operating group included three reporting units: Oil & Gas, Power and Plant Services. • Fabrication Services —Our Fabrication Services operating group included two reporting units: Steel Plate Structures and Fabrication & Manufacturing. • Technology —Our Technology operating group represented a reporting unit. • Environmental Solutions —Our Environmental Solutions operating group represented a reporting unit. First Quarter Reporting Unit Realignment —During the first quarter 2015, we realigned our four operating groups. In connection therewith, we realigned our reporting units, and accordingly, as of our October 1, 2015 annual impairment assessment date, we had the following eight reporting units within our four realigned operating groups, which represent our reportable segments as discussed further in Note 19 : • Engineering & Construction (formerly Engineering, Construction & Maintenance) —Our Engineering & Construction (“E&C”) operating group included two reporting units: Oil & Gas and Power (after the removal of our Nuclear Operations discussed further below). Our Plant Services reporting unit was reclassified to our realigned Capital Services operating group, as noted below. • Fabrication Services —Our Fabrication Services operating group included three reporting units: Steel Plate Structures, Fabrication & Manufacturing, and Engineered Products. Our Engineered Products reporting unit represents a portion of our previous Technology reporting unit. • Technology —Our Technology operating group continued to represent a reporting unit, consisting of the remaining portion of our previous Technology reporting unit, after reclassification of the Engineered Products reporting unit to Fabrication Services, as noted above. • Capital Services (formerly Environmental Solutions) —Our Capital Services operating group included two reporting units: Facilities & Plant Services and Federal Services. Our Facilities & Plant Services reporting unit represents our previous Plant Services reporting unit and a portion of our previous Environmental Solutions reporting unit. Our Federal Services reporting unit represents the remaining portion of our previous Environmental Solutions reporting unit. In conjunction with the aforementioned realignment of our operating groups, we allocated goodwill among our new and realigned reporting units based on the relative fair value of the reporting units being realigned. As a result, during the first quarter 2015, we performed a quantitative assessment of goodwill for each of the reporting units impacted by our operating group realignment (both immediately before and after the realignment). Based on this quantitative assessment, the fair value of each of the reporting units impacted by our operating group realignment exceeded their respective net book values, and accordingly, no impairment charge was necessary as a result of the realignment. Third Quarter Goodwill Impairment —As discussed further in Note 5 , we classified the assets and liabilities of our Nuclear Operations as held for sale at September 30, 2015, and on December 31, 2015 , we completed the sale of our Nuclear Operations. Our Nuclear Operations were included within our E&C operating group and were part of our Power reporting unit prior to the Agreement. Accordingly, in conjunction with the Agreement and classification of our Nuclear Operations as held for sale at September 30, 2015, we allocated the Power reporting unit’s goodwill between our Nuclear Operations and the remaining portion of the Power reporting unit after removal of the Nuclear Operations (“Retained Power Operations”), based on their relative fair values. Further, the Retained Power Operations became our Power reporting unit. The fair value of the Nuclear Operations was determined based on the Estimated Sales Proceeds. The fair value of the Retained Power Operations was determined on a basis consistent with the basis used for our annual impairment assessment discussed in Note 2 . Based on the aforementioned, the net book value of the Nuclear Operations (after allocating goodwill) exceeded its fair value, and accordingly, we concluded that the carrying value of all its goodwill was impaired. We also performed a quantitative assessment of goodwill for the Retained Power Operations and determined that the net book value of the Retained Power Operations (after allocating goodwill) exceeded its fair value, and accordingly, we concluded that the carrying value of its goodwill was partially impaired. The amount of goodwill impairment charge for the Retained Power Operations was determined by comparing the carrying value of its goodwill with its implied fair value. As a result of the aforementioned, during the third quarter 2015, we recorded a non-cash goodwill impairment charge of approximately $453,100 , of which approximately $191,000 related to the impairment of all goodwill of the Nuclear Operations and approximately $262,100 related to the partial impairment of goodwill of the Retained Power Operations. The impairment charge is included in “Goodwill impairment” in our Statement of Operations. Annual Impairment Assessment —As part of our annual goodwill impairment assessment during the fourth quarter of 2015, we performed a quantitative assessment of goodwill for each of the aforementioned reporting units as of October 1, 2015. Based upon this quantitative assessment, the fair value of each of our reporting units exceeded their respective net book values, and accordingly, no impairment charge was necessary as a result of our annual impairment assessment. 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. Fourth Quarter Reporting Unit Realignment —As a result of the Agreement, during the fourth quarter 2015, and subsequent to our annual goodwill impairment assessment performed as of October 1, 2015, our Retained Power Operations and Oil & Gas operations, both within our E&C operating group, were integrated and operationally combined. In addition, our Power and Oil & Gas reporting units were combined such that our E&C operating group currently represents a reporting unit. In conjunction with the aforementioned realignment of our E&C operating group and reporting units, we performed a quantitative assessment of goodwill for the Power and Oil & Gas reporting units immediately before the realignment, and for the E&C reporting unit immediately after the realignment. Based on this quantitative assessment, 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 realignment. Other Intangible Assets —The following table provides a summary of our acquired finite-lived intangible assets at December 31, 2015 and 2014 , including weighted-average useful lives for each major intangible asset class and in total: December 31, 2015 December 31, 2014 Weighted Average Life Gross Carrying Amount Accumulated Amortization Gross Carrying Amount Accumulated Amortization Finite-lived intangible assets Backlog and customer relationships (1)(2) 17 Years $ 281,072 $ (66,666 ) $ 380,586 $ (71,257 ) Process technologies 15 Years 271,028 (115,608 ) 287,459 (105,646 ) Tradenames (2) 10 Years 64,790 (23,667 ) 85,613 (20,301 ) Total (3) 16 Years $ 616,890 $ (205,941 ) $ 753,658 $ (197,204 ) (1) Backlog and customer relationships intangibles totaling approximately $11,000 became fully amortized during 2015 and were therefore removed from the December 31, 2015 gross carrying and accumulated amortization balances above. (2) During the third quarter 2015, we recorded a non-cash impairment charge of approximately $79,100 related to customer relationship and tradename intangible assets as a result of the Agreement to sell our Nuclear Operations described further in Note 5 . The impairment was based on a comparison of the carrying value of the intangible assets to their fair value (indicated by the Estimated Sales Proceeds), which resulted in an impairment of all intangible assets of the Nuclear Operations. The impairment charge is included in “Loss on net assets sold and intangible assets impairment” in our Statement of Operations and relates to our E&C operating group. The related intangibles were removed from the gross carrying and accumulated amortization balances above. We noted no other indicators of impairment during 2015 and no indicators of impairment during 2014. (3) The remaining decrease in other intangibles, net during 2015 primarily related to amortization expense of $57,625 and the impact of foreign currency translation. Amortization expense for our intangibles existing at December 31, 2015 is anticipated to be approximately $42,700 , $38,900 , $38,100 , $35,900 and $35,500 for 2016 , 2017 , 2018 , 2019 and 2020 , respectively.

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 VIEs: December 31, 2015 2014 CB&I/Zachry Current assets (1) $ 298,916 $ 85,484 Non-current assets 6,689 — Total assets $ 305,605 $ 85,484 Current liabilities (1) $ 454,943 $ 149,891 CB&I/Zachry/Chiyoda Current assets (1) $ 84,696 $ — Current liabilities (1) $ 86,124 $ — CB&I/Chiyoda Current assets (1) $ 424,781 $ 102,035 Current liabilities (1) $ 433,526 $ 124,367 (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 venture 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, 2015 and 2014 , other current assets on the Balance Sheet included approximately $325,000 and $71,200 , respectively, related to our proportionate share of advances from the ventures to our venture partners and other current liabilities included approximately $334,900 and $108,700 , 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: • Chevron-Lummus Global (“CLG”)— We have a venture with Chevron (CB&I— 50% / Chevron— 50% ), which provides licenses, engineering services and catalyst, primarily for the refining industry. As sufficient capital investments in CLG have been made by the venture partners, it does not qualify as a VIE. • NetPower LLC (“NetPower”)— We have a venture with Exelon and 8 Rivers Capital (CB&I— 33.3% / Exelon— 33.3% / 8 Rivers Capital— 33.3% ), which was formed for the purpose of developing, commercializing and monetizing a new natural gas power generation system that recovers essentially all the carbon dioxide produced during combustion. NetPower 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 NetPower and therefore do not consolidate it. Our cash commitment for NetPower totals $47,300 and at December 31, 2015 , we had made cumulative investments of approximately $17,900 . • CB&I/CTCI— We have a venture with CTCI Corporation (“CTCI”) (CB&I— 50% / CTIC— 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 CB&I/CTCI and therefore do not consolidate it. The project did not have a material impact on our results for 2015, but will become more significant as project activities progress. Dividends received from equity method joint ventures were $27,806 , $17,034 and $33,984 during 2015 , 2014 and 2013 , 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 $5,000,000 . • 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 $5,500,000 . The following table presents summarized balance sheet information for our consolidated VIEs: December 31, 2015 2014 CB&I/Kentz Current assets $ 214,291 $ 220,930 Current liabilities $ 191,471 $ 196,277 CB&I/AREVA Current assets $ 24,269 $ 27,006 Current liabilities $ 65,674 $ 73,124 All Other (1) Current assets $ 112,532 $ 130,458 Non-current assets 19,253 22,045 Total assets $ 131,785 $ 152,503 Current liabilities $ 32,001 $ 36,534 (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.

Debt Disclosure [Abstract]
DEBT	DEBT Our outstanding debt at December 31, 2015 and 2014 was as follows: December 31, 2015 2014 Current Revolving facility and other short-term borrowings $ 653,000 $ 164,741 Current maturities of long-term debt 150,000 105,997 Current debt $ 803,000 $ 270,738 Long-Term Term Loan: $1,000,000 term loan (interest at LIBOR plus an applicable floating margin) $ 450,000 $ 825,000 Second Term Loan: $500,000 term loan (interest at LIBOR plus an applicable floating margin) 500,000 — Senior Notes: $800,000 senior notes, series A-D (fixed interest ranging from 4.15% to 5.30%) 800,000 800,000 Second Senior Notes: $200,000 senior notes (fixed interest of 4.53%) 200,000 — Other long-term debt — 45,155 Less: current maturities of long-term debt (150,000 ) (105,997 ) Long-term debt $ 1,800,000 $ 1,564,158 Committed Facilities— We have a five -year, $1,350,000 , committed and unsecured revolving facility (the “Revolving Facility”) with Bank of America N.A. (“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 was amended on July 8, 2015 to remove the $675,000 borrowing sublimit while maintaining a $270,000 financial letter of credit sublimit. In conjunction with the sale of our Nuclear Operations discussed further in Note 5, the Revolving Facility was amended to reset our financial and restrictive covenants, which resulted in a maximum leverage ratio of 3.25 , a minimum fixed charge coverage ratio of 1.75 , and a minimum net worth level calculated as $1,560,389 at December 31, 2015 . 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 trailing 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 ), 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 ( 3.50% and 0.75% , respectively at December 31, 2015 ), or LIBOR plus an applicable floating margin ( 0.42% and 1.75% , respectively at December 31, 2015 ). At December 31, 2015 , we had no outstanding borrowings under the facility and $149,014 of outstanding letters of credit under the facility ( none of which were financial letters of credit), providing $1,200,986 of available capacity. During 2015 , our weighted average interest rate on borrowings under the facility was approximately 1.8% , 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 was amended on July 8, 2015 to increase the overall capacity from the previous capacity of $650,000 , extend the expiration date from the previous expiration of February 2018, remove the $487,500 borrowing sublimit and provide a financial letter of credit sublimit of $50,000 . The Second Revolving Facility supplements our Revolving Facility, and has financial and restrictive covenants similar to those noted above for the Revolving Facility. 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 ( 3.50% and 0.75% , respectively at December 31, 2015 ) or LIBOR plus an applicable floating margin ( 0.42% and 1.75% , respectively at December 31, 2015 ). At December 31, 2015 , we had $290,000 of outstanding borrowings and $15,533 of outstanding letters of credit under the facility (including $3,140 of financial letters of credit), providing $494,467 of available capacity. During 2015 , our weighted average interest rate on borrowings under the facility was approximately 3.8% , 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 $4,014,273 , of which $463,000 may be utilized for borrowings. At December 31, 2015 , we had $363,000 of outstanding borrowings and $1,393,104 of outstanding letters of credit under these facilities, providing $2,258,169 of available capacity, of which $100,000 may be utilized for borrowings. During 2015 , our weighted average interest rate on borrowings under the facility was approximately 1.2% . Term Loans —At December 31, 2015 , we had $450,000 outstanding on our 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 ( 0.42% and 1.75% , respectively at December 31, 2015 ). However, we continue to utilize an interest rate swap to hedge against $366,125 of the outstanding $450,000 Term Loan, which resulted in a weighted average interest rate of approximately 2.0% during 2015 , inclusive of the applicable floating margin. Future annual maturities for the Term Loan are $150,000 and $300,000 in 2016 and 2017 , respectively. The Term Loan includes financial and restrictive covenants similar to those noted above for the Revolving Facility. On July 8, 2015, we entered into a $500,000 unsecured term loan (the “Second Term Loan”). The Second Term Loan required that $275,000 of the loan proceeds be utilized to prepay a portion of the 2017 principal due on the Term Loan. 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 2015 , our weighted average interest rate on the Second Term was approximately 1.8% , 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 similar to those noted above for the Revolving Facility. 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 similar to those noted above for the Revolving Facility. 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 On July 30, 2015, we issued 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
FINANCIAL INSTRUMENTS	FINANCIAL INSTRUMENTS Derivatives Foreign Currency Exchange Rate Derivatives —At December 31, 2015 , the notional value of our outstanding forward contracts to hedge certain foreign exchange-related operating exposures was approximately $81,900 . These contracts vary in duration, maturing up to six 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. We exclude forward points, which are recognized as ineffectiveness within cost of revenue and are not material to our earnings, from our hedge assessment analysis. Interest Rate Derivatives— We continue to utilize a swap arrangement to hedge against interest rate variability associated with $366,125 of our outstanding $450,000 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, 2015 . Accordingly, changes in the fair value of the swap arrangement are recognized 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, 2015 or 2014 . The following table presents the fair value of our foreign currency exchange rate derivatives and interest rate derivatives at December 31, 2015 and 2014 , respectively, by valuation hierarchy and balance sheet classification: December 31, 2015 December 31, 2014 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Derivative Assets (1) Other current assets $ — $ 3,344 $ — $ 3,344 $ — $ 852 $ — $ 852 Other non-current assets — 180 — 180 — 2,248 — 2,248 Total assets at fair value $ — $ 3,524 $ — $ 3,524 $ — $ 3,100 $ — $ 3,100 Derivative Liabilities Other current liabilities $ — $ (7,567 ) $ — $ (7,567 ) $ — $ (12,728 ) $ — $ (12,728 ) Other non-current liabilities — (607 ) — (607 ) — (1,873 ) — (1,873 ) Total liabilities at fair value $ — $ (8,174 ) $ — $ (8,174 ) $ — $ (14,601 ) $ — $ (14,601 ) (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, 2015 , 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 are categorized within level 2 of the valuation hierarchy and had a total fair value of approximately $772,600 and $785,100 at December 31, 2015 and 2014 , respectively, based on current market rates for debt with similar credit risk and maturities. Our Second Senior Notes are categorized within level 2 of the valuation hierarchy and had a total fair value of approximately $203,500 at December 31, 2015 based on current market rates for debt with similar credit risk and maturities.

RETIREMENT BENEFITS	RETIREMENT BENEFITS Defined Contribution Plans We sponsor multiple defined contribution plans for eligible employees with various features including voluntary pre-tax salary deferrals, matching contributions, and savings plan contributions in the form of cash or our common stock, to be determined annually. During 2015 , 2014 and 2013 , we expensed $60,540 , $73,444 and $82,655 , respectively, for these plans. In addition, we sponsor several other defined contribution plans that cover salaried and hourly employees for which we do not provide contributions. The cost of these plans was not significant to us in 2015 , 2014 or 2013 . Defined Benefit Pension and Other Postretirement Plans We sponsor various defined benefit pension plans covering certain employees and provide specific health care and life insurance benefits for eligible retired U.S. employees through health care and life insurance benefit programs. These plans may be changed or terminated by us at any time. The following tables provide combined information for our defined benefit pension and other postretirement plans: Components of Net Periodic Benefit Cost Pension Plans Other Postretirement Plans 2015 2014 2013 2015 2014 2013 Service cost $ 10,611 $ 9,113 $ 6,795 $ 791 $ 1,037 $ 1,244 Interest cost 23,242 33,530 31,159 1,545 2,279 2,064 Expected return on plan assets (28,341 ) (36,577 ) (30,611 ) — — — Amortization of prior service credits (620 ) (465 ) (466 ) — — (266 ) Recognized net actuarial losses (gains) 7,648 4,649 4,555 (2,696 ) (863 ) (517 ) Net periodic benefit cost (income) $ 12,540 $ 10,250 $ 11,432 $ (360 ) $ 2,453 $ 2,525 Change in Projected Benefit Obligation Pension Plans Other Postretirement Plans 2015 2014 2015 2014 Projected benefit obligation at beginning of year $ 945,522 $ 882,471 $ 51,458 $ 46,637 Service cost 10,611 9,113 791 1,037 Interest cost 23,242 33,530 1,545 2,279 Actuarial (gain) loss (1) (45,456 ) 153,887 (20,863 ) 3,199 Plan participants’ contributions 2,828 3,443 452 1,625 Amendments — (4,119 ) — — Benefits paid (33,521 ) (35,945 ) (2,435 ) (3,319 ) Currency translation (2) (78,258 ) (96,858 ) — — Projected benefit obligation at end of year $ 824,968 $ 945,522 $ 30,948 $ 51,458 Change in Plan Assets Pension Plans Other Postretirement Plans 2015 2014 2015 2014 Fair value of plan assets at beginning of year $ 783,219 $ 779,626 $ — $ — Actual return on plan assets 1,211 95,294 — — Benefits paid (33,521 ) (35,945 ) (2,435 ) (3,319 ) Employer contributions (3) 16,918 19,957 1,983 1,694 Plan participants’ contributions 2,828 3,443 452 1,625 Currency translation (2) (63,567 ) (79,156 ) — — Fair value of plan assets at end of year $ 707,088 $ 783,219 $ — $ — Funded status $ (117,880 ) $ (162,303 ) $ (30,948 ) $ (51,458 ) Balance Sheet Position Pension Plans Other Postretirement Plans 2015 2014 2015 2014 Prepaid benefit cost within other non-current assets $ 13,581 $ 14,524 $ — $ — Accrued benefit cost within other current liabilities (2,699 ) (2,975 ) (2,432 ) (2,895 ) Accrued benefit cost within other non-current liabilities (128,762 ) (173,852 ) (28,516 ) (48,563 ) Net funded status recognized $ (117,880 ) $ (162,303 ) $ (30,948 ) $ (51,458 ) Unrecognized net prior service credits $ (3,975 ) $ (5,111 ) $ — $ — Unrecognized net actuarial losses (gains) 144,680 186,838 (31,571 ) (13,360 ) Accumulated other comprehensive loss (income), before taxes (4) $ 140,705 $ 181,727 $ (31,571 ) $ (13,360 ) (1) 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. The actuarial pension plan loss for 2014 was primarily associated with a decrease in discount rate assumptions for our pension plans. (2) The currency translation loss for 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 2016 , we expect to contribute approximately $16,900 and $2,400 to our pension and other postretirement plans, respectively. (4) During 2016 , we expect to recognize $(400) and $2,300 of previously unrecognized net prior service pension credits and net actuarial pension losses, respectively. Accumulated Benefit Obligation —At December 31, 2015 and 2014 , the accumulated benefit obligation for all defined benefit pension plans was $823,616 and $926,365 , respectively. The following table includes summary information for those defined benefit plans with an accumulated benefit obligation in excess of plan assets: December 31, 2015 2014 Projected benefit obligation $ 714,539 $ 824,988 Accumulated benefit obligation $ 713,187 $ 805,830 Fair value of plan assets $ 583,081 $ 648,162 Plan Assumptions —The following table reflects the weighted-average assumptions used to measure our defined benefit pension and other postretirement plans: Pension Plans Other Postretirement Plans 2015 2014 2015 2014 Weighted-average assumptions used to determine benefit obligations at December 31, Discount rate 2.95 % 2.64 % 4.47 % 4.13 % Rate of compensation increase (1) 2.37 % 2.76 % n/a n/a Weighted-average assumptions used to determine net periodic benefit cost for the years ended December 31, Discount rate 2.64 % 3.97 % 4.13 % 4.94 % Expected long-term rate of return on plan assets (2) 3.81 % 4.80 % n/a n/a Rate of compensation increase (1) 2.90 % 2.76 % n/a n/a (1) The rate of compensation increase relates solely to the defined benefit plans that factor compensation increases into the valuation.

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, 2015 , our target weighted-average asset allocations by asset category were: equity securities ( 35% - 40% ), fixed income securities ( 60% - 65% ), and other investments ( 0% - 5% ).

(b) Investments in European Union government securities with credit ratings of primarily AAA. (c) Investments in European fixed interest securities with credit ratings of primarily BBB and above. (d) Investments predominantly in U.K. Treasury securities with credit ratings of primarily AAA. (e) Investments predominantly in U.K. fixed interest securities with credit ratings of primarily BBB and above. (f) Investments predominantly in various international fixed income obligations that are individually insignificant. (g) Investments in fixed income securities, equities and alternative asset classes, including commodities and property assets. 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. Health Care Cost Inflation —As noted above, we provide specific medical benefits for certain groups of retirees and their dependents in the U.S., subject to vesting requirements. Under our program in the U.S., certain 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 service of each retired employee. Additionally, there is a closed group of U.S. 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 6.5% in 2016 down to 5% in 2020 and beyond. Under the U.S. program, since 2011, new employees are not eligible for post-retirement medical benefits. A change in the assumed health care cost trends by one percentage point for our U.S. program is estimated to have an immaterial impact on the total service and interest cost components of net postretirement health care cost for 2015 and the accumulated postretirement benefit obligation at December 31, 2015 . 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.

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 $151,660 , $144,288 and $147,100 for 2015 , 2014 and 2013 , respectively. Future minimum payments under non-cancelable operating leases having initial terms of one year or more are as follows: Year Amount 2016 $ 87,276 2017 70,517 2018 61,109 2019 49,668 2020 39,711 Thereafter 117,213 Total $ 425,494 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 —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 future results of operations, financial position or cash flow. See Note 18 for additional discussion of claims associated with our projects. 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, 2015 , we have been named a defendant in lawsuits alleging exposure to asbestos involving approximately 5,800 plaintiffs and, of those claims, approximately 1,200 claims were pending and 4,600 have been closed through dismissals or settlements. Over the past several decades and through December 31, 2015 , 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, 2015 , we had approximately $5,800 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 2016 or 2017 . 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. At December 31, 2015 , we had provided $2,223,840 of surety bonds and letters of credit to support our contracting activities in the ordinary course of business. This amount fluctuates based upon the mix and level of contracting activity. 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, 2015 , we had outstanding surety bonds and letters of credit of $82,661 relating to our insurance programs. Income Taxes —Income tax and associated interest 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 receive 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 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 $53,086 , $64,613 and $62,251 for 2015 , 2014 and 2013 , respectively. At December 31, 2015 , 3,596 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 $3,042 , $3,143 and $2,188 for 2015 , 2014 and 2013 , respectively. At December 31, 2015 , 3,268 authorized shares remained available for purchase under the ESPP. Total stock-based compensation expense for our Incentive Plans and ESPP was $56,128 , $67,756 and $64,439 for 2015 , 2014 and 2013 , respectively. At December 31, 2015 , there was $56,521 of unrecognized compensation cost related to share-based grants, which is expected to be recognized over a weighted-average period of 1.6 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. The total recognized tax benefit based on our compensation expense was $16,924 , $19,394 and $25,123 for 2015 , 2014 and 2013 , respectively. 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 2015 : Shares Weighted-Average Grant-Date Fair Value per Share Nonvested RSUs Balance at December 31, 2014 973 $ 64.15 Granted 1,015 $ 42.19 Vested (490 ) $ 54.45 Forfeited (113 ) $ 62.00 Balance at December 31, 2015 1,385 $ 51.65 Directors’ RSUs Balance at December 31, 2014 17 $ 80.45 Granted 28 $ 49.55 Vested (17 ) $ 80.45 Balance at December 31, 2015 28 $ 49.55 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 . During 2013 , 718 RSUs (including 18 directors’ shares subject to restrictions) were granted with a weighted-average grant-date fair value per share of $53.09 . The total fair value of RSUs that vested during 2015 , 2014 , and 2013 was $28,081 , $17,093 and $32,041 , respectively. Performance Based Shares —Our performance based share awards are subject to the achievement of specified Company performance targets, including financial performance or stock price performance relative to peers. • 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 2015 , we recognized $25,370 of compensation expense. During 2015 , 2014 and 2013 , financial performance-based shares totaling 702 , 312 , and 366 , respectively, were granted with a weighted-average grant-date fair value per share of $41.67 , $79.86 , and $57.40 , respectively. During 2015 , we distributed 563 financial performance-based shares upon vesting and achievement of certain performance goals and the total fair value of shares that vested was $23,463 . • Stock Performance-Based Grants —Stock performance-based share awards are based upon stock price performance relative to industry peers and cliff vest at the end of four 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 2015 , we recognized $1,216 of compensation expense. 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% , expected dividend yield of 0.69% , historical volatility of 39% and a remaining performance period of 3.9 years. There were no stock performance-based shares granted during 2014 or 2013 and there were no vestings in 2015 . Stock Options — Stock options are generally granted at the market value 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 2015 or 2014 . For options granted during 2013 the weighted-average fair value per share was $20.05 and was based upon a risk-free interest rate of 0.16% , expected dividend yield of 0.38% , expected volatility of 50% and an expected life of 5 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 options granted represents the period of time that they are expected to be outstanding. We also use historical information to estimate option exercises and forfeitures. The aggregate intrinsic value of options exercised was $1,126 , $12,218 and $23,546 for 2015 , 2014 and 2013 , respectively. During 2015 , we received net cash proceeds of $1,947 , and realized an actual income tax benefit of $416 , from the exercise of stock options. The following table represents stock option activity for 2015 : Shares Weighted Average Exercise Price per Share Weighted Average Remaining Contractual Life (in Years) Aggregate Intrinsic Value Outstanding options at December 31, 2014 753 $ 22.36 Exercised (63 ) $ 30.86 Forfeited / Expired (10 ) $ 39.39 Outstanding options at December 31, 2015 (1) 680 $ 21.32 2.9 $ 13,675 Exercisable options at December 31, 2015 641 $ 21.42 2.8 $ 12,943 (1) We estimate that 675 of these options will ultimately vest. These options have a weighted-average exercise price per share of $21.31 , a weighted-average remaining contractual life of 2.9 years and a current aggregate intrinsic value of $13,601 .

The following is a reconciliation of income taxes at The Netherlands’ (our country of domicile) statutory rate to income tax benefit (expense) for 2015 , 2014 and 2013 : Years Ended December 31, 2015 2014 2013 Income tax benefit (expense) at statutory rate (25.0% for 2015, 2014 and 2013) $ 127,798 $ (226,885 ) $ (150,965 ) U.S. state income taxes (1,965 ) (13,561 ) (4,356 ) Non-deductible meals and entertainment (10,930 ) (8,549 ) (4,878 ) Non U.S. valuation allowance established (1,989 ) (12,875 ) (13,952 ) Non U.S. valuation allowance utilized 5,251 15,899 87,609 Statutory tax rate differential 96,555 (40,990 ) (16,587 ) Branch and withholding taxes (net of tax benefit) 692 (1,941 ) 9,195 Previously unrecognized tax benefit (expense) 15,960 (5,412 ) (1,568 ) Noncontrolling interests 20,306 22,122 13,238 Non-deductible goodwill impairment (158,585 ) — — Other, net (11,862 ) 775 (9,006 ) Income tax benefit (expense) $ 81,231 $ (271,417 ) $ (91,270 ) Effective tax rate 15.9 % 29.9 % 15.1 % Deferred Taxes —The principal temporary differences included in deferred income taxes reported on the December 31, 2015 and 2014 Balance Sheets were as follows: December 31, 2015 2014 Deferred Tax Assets U.S. Federal operating losses and credits $ 626,232 $ 208,212 U.S. State operating losses and credits 195,996 73,028 Non-U.S. operating losses 56,612 79,970 Contract revenue and cost 63,876 428,546 Employee compensation and benefit plan reserves 75,754 101,598 Insurance and legal reserves 25,215 24,113 Disallowed interest 124,876 31,859 Other 9,520 67,023 Total deferred tax assets $ 1,178,081 $ 1,014,349 Valuation allowance (167,053 ) (104,414 ) Net deferred tax assets $ 1,011,028 $ 909,935 Deferred Tax Liabilities Investment in foreign subsidiaries $ (79,021 ) $ (68,652 ) Depreciation and amortization (308,619 ) (351,670 ) Net deferred tax liabilities $ (387,640 ) $ (420,322 ) Net total deferred tax assets $ 623,388 $ 489,613 At December 31, 2015 , we did not provide deferred income taxes on temporary differences of approximately $962,000 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 the 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. During 2015 , our VA increased by approximately $62,600 , primarily due to the establishment of VA against U.S.-State net operating losses (“NOL(s)”) generated in 2015 as a result of the impact of the Agreement and sale of our Nuclear Operations (approximately $58,000 ). During 2013, we released VA related to NOLs for our operations in the United Kingdom (“U.K.”), resulting in a decrease in tax expense of $62,800 . At December 31, 2015 , we had total Non-U.S. NOLs of $254,000 , including $148,000 in the U.K. and $106,000 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 $98,700 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, 2015 , our net DTA associated with Non-U.S. NOLs was $27,100 . Excluding NOLs having an indefinite carryforward, principally in the U.K., the Non-U.S. NOLs will expire from 2016 to 2035 . At December 31, 2015 , we had U.S.-Federal NOLs of $1,703,800 . Of the U.S.-Federal NOLs, $551,400 were generated prior to 2014 and will expire in 2033 . The remaining $1,152,400 of U.S.-Federal NOLs were generated in 2015 as a result of the Agreement and 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, 2015 , our DTA associated with the U.S. Federal NOLs was $596,300 . At December 31, 2015 , we had U.S.-State NOL DTAs of $192,200 . We believe it is more likely than not that $130,000 of the U.S.-State NOL DTAs will not be utilized and have placed a VA against these NOL DTAs. Accordingly, at December 31, 2015 , our net DTA associated with U.S.-State NOLs was $62,200 . The U.S.-State NOLs will expire from 2016 to 2035 . At December 31, 2015 , we had foreign tax credits and other tax credits of $19,000 and $14,900 , respectively. We believe it is more likely than not that the credits will be realized within the carryforward periods. Unrecognized Income Tax Benefits —At December 31, 2015 and 2014 , our unrecognized income tax benefits totaled $9,140 and $13,458 , 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, 2015 and 2014 : Years Ended December 31, 2015 2014 Unrecognized income tax benefits at the beginning of the year $ 13,458 $ 14,281 Increase as a result of: Tax positions taken during the current period 1,313 922 Decreases as a result of: Lapse of applicable statute of limitations (2,927 ) (1,745 ) Settlements with taxing authorities (2,704 ) — Unrecognized income tax benefits at the end of the year (1) $ 9,140 $ 13,458 (1) If these income tax benefits were ultimately recognized, approximately $6,000 and $10,300 of the December 31, 2015 and 2014 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 2015 , 2014 , and 2013 , interest and penalties were not significant.

Contractors [Abstract]
UNAPPROVED CHANGE ORDERS, CLAIMS, INCENTIVES AND OTHER CONTRACT RECOVERIES	UNAPPROVED CHANGE ORDERS, CLAIMS, INCENTIVES AND OTHER CONTRACT RECOVERIES At December 31, 2015 and 2014 , we had unapproved change orders and claims included in project price totaling approximately $98,500 and $1,309,700 , respectively, for projects primarily within our Engineering & Construction and Fabrication Services operating groups. The balance at December 31, 2014 included approximately $1,211,600 of unapproved change orders and claims attributable to our two nuclear projects in South Carolina and Georgia (collectively, the “Nuclear Projects”) that were part of our Nuclear Operations sold on December 31, 2015, as discussed in Note 5 . At December 31, 2015 and 2014 we also had incentives included in project price of approximately $99,300 and $32,600 , respectively, for projects in our Engineering & Construction, Fabrication Services and Capital Services operating groups. Of the aforementioned unapproved change orders, claims and incentives, approximately $166,000 had been recognized as revenue on a cumulative POC basis through December 31, 2015. At December 31, 2015 , we also had approximately $106,000 of receivables outstanding for one of our large cost reimbursable projects, of which approximately $71,900 was past due. A review and assessment of this project by governmental oversight agencies could result in past due amounts increasing in size and duration, and impact the formal approval of amounts previously received from the customer. Although the amounts may not be received in the near term, we believe they are contractually due under the provisions of our contract and are recoverable. 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.

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 four operating groups, which represent our reportable segments. As discussed in Note 1 and 7, during the first quarter 2015, we realigned our four operating groups to reflect the present management oversight of our operations. Our maintenance business that was previously reported within our Engineering & Construction operating group (formerly Engineering, Construction & Maintenance) is now reported within our Capital Services operating group (formerly Environmental Solutions), and our engineered products business that was previously reported within our Technology operating group is now reported within our Fabrication Services operating group. The segment results for 2014 and 2013 were reclassified to conform to the 2015 presentation. The following provides a description of our realigned operating groups: 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; manufacturing and distribution of pipe and fittings; and engineered products for the oil and gas, petrochemical, power generation, water and wastewater, mining and mineral processing industries. Technology —Technology provides licensed process technologies and catalysts for use in petrochemical facilities and oil refineries, and offers process planning and project development services and a comprehensive program of aftermarket support. Technology also has a 50% owned unconsolidated CLG joint venture that provides licensed technologies, engineering services and catalyst, primarily for the refining industry. Capital Services —Capital Services provides comprehensive and integrated maintenance services, environmental engineering and remediation, infrastructure EPC services, program management, and disaster response and recovery for private-sector customers and governments. Our Chief Executive Officer evaluates the performance of the aforementioned 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 is netted against the revenue of the segment receiving the intersegment services. For 2015 , 2014 , and 2013 , intersegment revenue totaled approximately $395,900 , $480,400 , and $237,100 , respectively, and primarily related to services provided by our Fabrication Services operating group to our Engineering & Construction operating group. The following table presents total revenue, depreciation and amortization, equity earnings, income from operations, capital expenditures by reportable segment for 2015 , 2014 , and 2013 : Years Ended December 31, 2015 2014 2013 Revenue Engineering & Construction $ 7,697,684 $ 7,623,381 $ 6,215,235 Fabrication Services 2,442,690 2,738,981 2,777,384 Technology 399,099 385,126 397,408 Capital Services 2,390,031 2,227,442 1,704,500 Total revenue $ 12,929,504 $ 12,974,930 $ 11,094,527 Depreciation And Amortization Engineering & Construction $ 48,388 $ 62,517 $ 64,321 Fabrication Services 56,310 61,344 60,747 Technology 22,864 23,703 21,180 Capital Services 33,573 33,834 33,778 Total depreciation and amortization $ 161,135 $ 181,398 $ 180,026 Equity Earnings Engineering & Construction $ (2,427 ) $ — $ — Fabrication Services (3,812 ) (77 ) 248 Technology 21,016 24,613 22,356 Capital Services 912 689 870 Total equity earnings $ 15,689 $ 25,225 $ 23,474 (Loss) Income From Operations Engineering & Construction (1) $ (875,321 ) $ 518,671 $ 316,737 Fabrication Services 225,267 274,487 287,942 Technology 150,877 147,782 128,643 Capital Services 74,060 81,353 46,923 Total operating groups $ (425,117 ) $ 1,022,293 $ 780,245 Acquisition and integration related costs — (39,685 ) (95,737 ) Total (loss) income from operations $ (425,117 ) $ 982,608 $ 684,508 Capital Expenditures Engineering & Construction $ 14,484 $ 42,152 $ 16,455 Fabrication Services 41,434 44,594 38,624 Technology 8,091 9,730 16,302 Capital Services 14,843 21,148 19,111 Total capital expenditures $ 78,852 $ 117,624 $ 90,492 (1) As discussed in Note 5 , due to the Agreement and sale of our Nuclear Operations, during 2015, we recorded a non-cash pre-tax charge of approximately $1,505,900 within our Engineering & Construction operating group. In conjunction with the aforementioned realignment of our operating groups during the first quarter 2015, our total assets by reportable segment changed significantly, including an allocation of goodwill among our new and realigned operating groups and reporting units based on the relative fair value of the reporting units being realigned. At December 31, 2015, 2014 and 2013, our total assets by reportable segment were as follows (with December 31, 2014 and 2013 balances reflecting the realignment of our operating groups to conform with the 2015 presentation): December 31, 2015 2014 2013 Assets Engineering & Construction $ 4,131,767 $ 4,555,703 $ 4,609,777 Fabrication Services 2,552,870 2,229,346 2,390,875 Technology 821,640 837,445 802,784 Capital Services 1,696,080 1,758,537 1,586,157 Total assets $ 9,202,357 $ 9,381,031 $ 9,389,593 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, 2015 2014 2013 Revenue by Country United States $ 8,408,633 $ 6,682,054 $ 5,007,899 Australia 2,172,026 2,498,848 1,574,253 Other (1) 2,348,845 3,794,028 4,512,375 Total revenue $ 12,929,504 $ 12,974,930 $ 11,094,527 (1) Revenue earned in other countries, including The Netherlands (our country of domicile), was not individually greater than 10% of our consolidated revenue in 2015 , 2014 , or 2013 . Our long-lived assets are primarily goodwill, other intangible assets and property and equipment. At December 31, 2015 , 2014 and 2013 , approximately 80% , 80% and 80% 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, 2015 , 2014 , or 2013 . Significant Customers For 2015 , 2014 , and 2013 , revenue for a customer in our E&C and Fabrication Services operating groups was $1,646,997 , $1,955,774 , and $1,190,787 , respectively (approximately 13% , 15% , and 11% , respectively, of our total 2015 , 2014 , and 2013 revenue).

SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Accounting and Consolidation	Basis of Accounting and Consolidation —The accompanying Consolidated Financial Statements (“Financial Statements”) are 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”). 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. Significant intercompany balances and transactions are eliminated in consolidation.
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	Any uncollected billed amounts, including contract retentions, are reported as accounts receivable. At December 31, 2015 and 2014 , accounts receivable included contract retentions of approximately $62,900 and $53,000 , respectively. Contract retentions due beyond one year were not material at December 31, 2015 or 2014 . 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 approximately $71,600 and $66,900 at December 31, 2015 and 2014 , respectively. 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, 2015 and 2014 , our allowances for doubtful accounts were not material. 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. 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 2015 , 2014 , and 2013 , individual projects with significant changes in estimated margins did not have a material net impact on our income from operations. 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 estimate of recovery amounts; however, the ultimate resolution and amounts received could differ from these estimates. See Note 18 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 is reported on the Consolidated Balance Sheet (“Balance Sheet”) as costs and estimated earnings in excess of billings. Projects with cumulative billings in excess of costs and estimated earnings recognized to date is reported on the Balance Sheet as billings in excess of costs and estimated earnings.
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, 2015 or 2014 .
Research and Development	Research and Development —Expenditures for research and development activities are charged to cost of revenue as incurred and were $28,301 , $28,432 and $27,071 for 2015 , 2014 and 2013 , 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 gain of approximately $7,500 related to the contribution of a technology to our unconsolidated Chevron-Lummus Global (“CLG”) joint venture and a foreign exchange loss of approximately $11,000 associated with the re-measurement of certain non-U.S. Dollar denominated net assets.
Acquisition and Integration-Related Costs	Acquisition and Integration Related Costs —Acquisition and integration related costs were $39,685 and $95,737 for 2014 and 2013, respectively. For 2014 and 2013, integration related costs 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. For 2013, acquisition related costs primarily related to transaction costs, professional fees, and change-in-control and severance related costs associated with the Shaw Acquisition.
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 $103,510 , $114,892 and $118,915 for 2015 , 2014 and 2013 , respectively. See Note 9 for disclosure of the components of property and equipment.
Recoverability of Goodwill/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. See Note 7 for additional discussion of our goodwill and related goodwill impairment recorded during 2015 . Recoverability of Other Long-Lived Assets —We amortize our finite-lived intangible assets on a straight-line basis with lives ranging from 3 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 and related impairment recorded during 2015 .
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 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 disclosures associated with 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 2015 , 2014 and 2013 .
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, 2015 , we continued to utilize a swap arrangement to hedge against interest rate variability associated with $366,125 of our outstanding $450,000 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, 2015 . 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 12 for additional discussion of our financial instruments.
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 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 17 for additional discussion of our income taxes.
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 proportionate consolidation for both our Balance Sheet and Statement of Operations when we meet the applicable accounting criteria to do so and utilize the equity method otherwise. See Note 8 for additional discussion of our material partnering arrangements.
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. In August 2015, the FASB issued ASU 2015-14, which delays the effective date of ASU 2014-09 by one year while allowing for early adoption as of the original effective date. CB&I will adopt the standard beginning in the first quarter 2018 in accordance with the provisions of ASU 2015-14. The new standard prescribes a five-step revenue recognition model that focuses on transfer of control and entitlement to consideration in determining the amount of revenue to be recognized. The guidance also significantly expands qualitative and quantitative disclosure requirements regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Our adoption of ASU 2014-09 will result in retrospective application, either in the form of recasting all prior periods presented or a cumulative adjustment to equity in the period of adoption. We are assessing the impact that the new standard will have on our Financial Statements. In February 2015, the FASB issued ASU 2015-02, which amends existing consolidation requirements in ASC 810 and will require entities to evaluate their consolidation analysis for subsidiaries that are not wholly-owned. ASU 2015-02 includes amended guidance 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. ASU 2015-02 is effective for us beginning in the first quarter 2016. We do not expect the adoption of ASU 2015-02 to have a material impact on our consolidated financial position, results of operations, or cash flows. In April 2015, the FASB issued ASU 2015-03, which changes the presentation of debt issuance costs. Upon adoption, debt issuance costs would be presented as a direct deduction from the related debt liability rather than as an asset, as currently presented. ASU 2015-03 is effective for us beginning in the first quarter 2016. We do not expect the adoption of ASU 2015-03 to have a material impact on our consolidated financial position, results of operations, or cash flows. In November 2015, the FASB issued ASU 2015-17, which requires deferred tax assets and deferred tax liabilities to be presented as non-current, rather than separately presented as current and non-current, on the balance sheet. ASU 2015-17 is effective for us beginning in the first quarter 2017; however, as permitted, we early adopted ASU 2015-17 effective October 1, 2015. We chose to apply the standard prospectively with our December 31, 2015 deferred taxes presented as non-current on our Balance Sheet. The December 31, 2014 presentation of deferred taxes was not retrospectively adjusted.

Accordingly, the goodwill balances at December 31, 2014 and 2013 were reclassified to conform to the 2015 presentation. (2) At December 31, 2015, we had $453,100 in accumulated impairment losses.

(2) During the third quarter 2015, we recorded a non-cash impairment charge of approximately $79,100 related to customer relationship and tradename intangible assets as a result of the Agreement to sell our Nuclear Operations described further in Note 5 . The impairment was based on a comparison of the carrying value of the intangible assets to their fair value (indicated by the Estimated Sales Proceeds), which resulted in an impairment of all intangible assets of the Nuclear Operations. The impairment charge is included in “Loss on net assets sold and intangible assets impairment” in our Statement of Operations and relates to our E&C operating group. The related intangibles were removed from the gross carrying and accumulated amortization balances above. We noted no other indicators of impairment during 2015 and no indicators of impairment during 2014. (3) The remaining decrease in other intangibles, net during 2015 primarily related to amortization expense of $57,625 and the impact of foreign currency translation. Amortization expense for our intangibles existing at December 31, 2015 is anticipated to be approximately $42,700 , $38,900 , $38,100 , $35,900 and $35,500 for 2016 , 2017 , 2018 , 2019 and 2020 , respectively.

[1]	The remaining decrease in other intangibles, net during 2015 primarily related to amortization expense of $57,625 and the impact of foreign currency translation. Amortization expense for our intangibles existing at December 31, 2015 is anticipated to be approximately $42,700, $38,900, $38,100, $35,900 and $35,500 for 2016, 2017, 2018, 2019 and 2020, respectively.
[2]	Backlog and customer relationships intangibles totaling approximately $11,000 became fully amortized during 2015 and were therefore removed from the December 31, 2015 gross carrying and accumulated amortization balances above.
[3]	During the third quarter 2015, we recorded a non-cash impairment charge of approximately $79,100 related to customer relationship and tradename intangible assets as a result of the Agreement to sell our Nuclear Operations described further in Note 5. The impairment was based on a comparison of the carrying value of the intangible assets to their fair value (indicated by the Estimated Sales Proceeds), which resulted in an impairment of all intangible assets of the Nuclear Operations. The impairment charge is included in “Loss on net assets sold and intangible assets impairment” in our Statement of Operations and relates to our E&C operating group. The related intangibles were removed from the gross carrying and accumulated amortization balances above. We noted no other indicators of impairment during 2015 and no indicators of impairment during 2014.

[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.

[1]	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. The actuarial pension plan loss for 2014 was primarily associated with a decrease in discount rate assumptions for our pension plans.
[2]	The currency translation loss for 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 2016, we expect to contribute approximately $16,900 and $2,400 to our pension and other postretirement plans, respectively.
[4]	During 2016, we expect to recognize $(400) and $2,300 of previously unrecognized net prior service pension credits and net actuarial pension losses, respectively.
