| Summary of Significant Accounting Policies (Policies) | 12 Months Ended |
| Dec. 31, 2018 |
| Accounting Policies [Abstract] | |
| Recent Developments | Recent Developments: During 2018, we revised our reportable segments, which are the same as our operating segments, as a result of a change in how our chief operating decision maker (our Chief Executive Officer) regularly reviews financial information to allocate resources and assess performance. This change is consistent with our strategic, end-market diversification strategy. Our new reportable segments which correspond to this end-market focus are: Transportation, Water, Specialty and Materials. The Transportation, Water and Specialty end-market segments replace the Construction and Large Project Construction reportable segments with the composition of our Materials segment remaining unchanged except for the addition of proprietary sanitary and storm water rehabilitation products including cured-in-place pipe felt and fiberglass-based lining tubes related to the acquisition of Layne Christensen Company (“Layne”). Prior-year information has been recast to reflect this change. See Note 22 for further information regarding our reportable segments. In addition, on April 3, 2018, we acquired LiquiForce and on June 14, 2018, we completed the acquisition of Layne. See Note 2 for further information. |
| Principles of Consolidation | Principles of Consolidation : The consolidated financial statements include the accounts of Granite Construction Incorporated and its wholly owned and consolidated subsidiaries. All material inter-company transactions and accounts have been eliminated. Additionally, we participate in various joint ventures (“joint ventures”). We consolidate these joint ventures where we have determined that through our participation we have a variable interest and are the primary beneficiary as defined by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810, , and related standards. The factors we use to determine the primary beneficiary of a variable interest entity (“VIE”) may include the decision authority of each partner, which partner manages the day-to-day operations of the project and the amount of our equity investment in relation to that of our partners. Although not applicable for any of the years presented, if we determine that the power to direct the significant activities is shared equally by two or more joint venture parties, then there is no primary beneficiary and no party consolidates the VIE. Where we have determined we are not the primary beneficiary of a joint venture but do exercise significant influence, we account for our share of the operations of unconsolidated construction joint ventures on a pro rata basis in revenue and cost of revenue in the consolidated statements of operations and in equity in construction joint ventures in the consolidated balance sheets. Our investment in unconsolidated construction joint ventures could extend beyond one year and is within the normal operating cycle of the associated construction projects. We account for non-construction unconsolidated joint ventures under the equity method of accounting in accordance with ASC Topic 323, Investments - Equity Method and Joint Ventures |
| Use of Estimates in the Preparation of Financial Statements | Use of Estimates in the Preparation of Financial Statements : The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of these financial statements requires management to make estimates that affect the reported amounts of assets and liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. Our estimates and related judgments and assumptions are continually evaluated based on available information and experiences; however, actual amounts could differ from those estimates. |
| Revenue Recognition | Revenue Recognition: Our revenue is primarily derived from construction contracts that can span several quarters or years and from sales of construction related materials. We recognize revenue in accordance with ASC Topic 606, and subsequently issued additional related ASUs (“Topic 606”). Topic 606 provides for a five-step model for recognizing revenue from contracts with customers as follows:
1.
Identify the contract
2.
Identify performance obligations
3.
Determine the transaction price
4.
Allocate the transaction price
5.
Recognize revenue Generally, our contracts contain one performance obligation. The transaction price is the amount of consideration to which we expect to be entitled in exchange for transferring goods and services to the customer. The consideration promised in a contract with customers of our Transportation, Water and Specialty segments may include both fixed amounts and variable amounts (e.g. bonuses/incentives or penalties/liquidated damages) to the extent that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved (i.e., probable and estimable). When a contract has a single performance obligation, the entire transaction price is attributed to that performance obligation. When a contract has more than one performance obligation, the transaction price is allocated to each performance obligation based on estimated relative standalone selling prices of the goods or services at the inception of the contract, which typically is determined using cost plus an appropriate margin. Subsequent to the inception of a contract in our Transportation, Water and Specialty segments, the transaction price could change for various reasons, including the executed or estimated amount of change orders and unresolved contract modifications and claims to or from owners. Changes that are accounted for as an adjustment to existing performance obligations are allocated on the same basis at contract inception. Otherwise, changes are accounted for as separate performance obligation(s) and the separate transaction price is allocated as discussed above. Changes are made to the transaction price from unapproved change orders to the extent the amount can be reasonably estimated and recovery is probable. On certain projects we have submitted and have pending unresolved contract modifications and affirmative claims (“affirmative claims”) to recover additional costs and the associated profit, if applicable, to which the Company believes it is entitled under the terms of contracts with customers, subcontractors, vendors or others. The owners or their authorized representatives and/or other third parties may be in partial or full agreement with the modifications or affirmative claims, or may have rejected or disagree entirely or partially as to such entitlement. Changes are made to the transaction price from affirmative claims with customers to the extent that additional revenue on a claim settlement with a customer is probable and estimable. A reduction to costs related to affirmative claims with non-customers with whom we have a contractual arrangement (“back charges”) is recognized when the recovery is probable and estimable. Recognizing affirmative claims and back charge recoveries requires significant judgments of certain factors including, but not limited to, dispute resolution developments and outcomes, anticipated negotiation results, and the cost of resolving such matters. Certain construction contracts include retention provisions to provide assurance to our customers that we will perform in accordance with the contract terms and are not considered a financing benefit. The balances billed but not paid by customers pursuant to these provisions generally become due upon completion and acceptance of the project work or products by the customer. We have determined there are no significant financing components in our contracts during the year ended December 31, 2018. Typically, performance obligations related to contracts in our Transportation, Water and Specialty segments are satisfied over time because our performance typically creates or enhances an asset that the customer controls as the asset is created or enhanced. We recognize revenue as performance obligations are satisfied and control of the promised good and/or service is transferred to the customer. Revenue in our Transportation, Water and Specialty segments is ordinarily recognized over time as control is transferred to the customers by measuring the progress toward complete satisfaction of the performance obligation(s) using an input (i.e., “cost to cost”) method. Under the cost to cost method, costs incurred to-date are generally the best depiction of transfer of control. All contract costs, including those associated with affirmative claims, change orders and back charges, are recorded as incurred and revisions to estimated total costs are reflected as soon as the obligation to perform is determined. Contract costs consist of direct costs on contracts, including labor and materials, amounts payable to subcontractors, direct overhead costs and equipment expense (primarily depreciation, fuel, maintenance and repairs). The accuracy of our revenue and profit recognition in a given period depends on the accuracy of our estimates of the cost to complete each project. Cost estimates for all of our significant projects use a detailed “bottom up” approach, and we believe our experience allows us to create materially reliable estimates. There are a number of factors that can contribute to changes in estimates of contract cost and profitability. The most significant of these include:
•
the completeness and accuracy of the original bid;
•
costs associated with scope changes;
•
changes in costs of labor and/or materials;
•
extended overhead and other costs due to owner, weather and other delays;
•
subcontractor performance issues;
•
changes in productivity expectations;
•
site conditions that differ from those assumed in the original bid;
•
changes from original design on design-build projects;
•
the availability and skill level of workers in the geographic location of the project;
•
a change in the availability and proximity of equipment and materials;
•
our ability to fully and promptly recover on affirmative claims and back charges for additional contract costs; and
•
the customer’s ability to properly administer the contract. The foregoing factors, as well as the stage of completion of contracts in process and the mix of contracts at different margins may cause fluctuations in gross profit and gross profit margin from period to period. Significant changes in cost estimates, particularly in our larger, more complex projects have had, and can in future periods have, a significant effect on our profitability. All state and federal government contracts and many of our other contracts provide for termination of the contract at the convenience of the party contracting with us, with provisions to pay us for work performed through the date of termination including demobilization cost. Costs to obtain our contracts (“pre-bid costs”) that are not expected to be recovered from the customer are expensed as incurred and included in selling, general and administrative expenses on our consolidated statements of operations. Although unusual, pre-bid costs that are explicitly chargeable to the customer even if the contract is not obtained are included in accounts receivable on our consolidated balance sheets when we are notified that we are not the low bidder with a corresponding reduction to selling, general and administrative expenses on our consolidated statements of operations. |
| Unearned Revenue | Unearned Revenue: Unearned revenue represents the aggregate amount of the transaction price allocated to unsatisfied or partially unsatisfied performance obligations at the end of a reporting period. We generally include a project in our unearned revenue at the time a contract is awarded, the contract has been executed and to the extent we believe funding is probable. Certain contracts contain contract options that are exercisable at the option of our customers without requiring us to go through an additional competitive bidding process or contain task orders related to master contracts under which we perform work only when the customer awards specific task orders to us. Contract options and task orders are included in unearned revenue when exercised or issued, respectively. Substantially all of the contracts in our unearned revenue may be canceled or modified at the election of the customer; however, we have not been materially adversely affected by contract cancellations or modifications in the past. Many projects are added to unearned revenue and completed within the same fiscal quarter or year and, therefore, may not be reflected in our beginning or ending unearned revenue. Approximately $1.9 billion of the December 31, 2018 unearned revenue is expected to be recognized within the next twelve months and the remaining amount will be recognized thereafter. Unearned revenue is presented by reportable segment and operating group in Note 5. Costs to mobilize equipment and labor to a job site prior to substantive work beginning (“mobilization costs”) are capitalized as incurred and amortized over the expected duration of the contract. As of December 31, 2018 and January 1, 2018, we had no material capitalized mobilization costs. |
| Balance Sheet Classification | Balance Sheet Classifications: Prepaid expenses and amounts receivable and payable under construction contracts (principally retentions) that may exist over the duration of the contract and could extend beyond one year are included in current assets and liabilities. A one-year time period is used as the basis for classifying all other current assets and liabilities. |
| Cash, Cash Equivalents and Restricted Cash | Cash, Cash Equivalents and Restricted Cash : Cash equivalents are securities having maturities of three months or less from the date of purchase. Included in cash and cash equivalents in the consolidated balance sheets as of December 31, 2018 and 2017, was $132.0 million and $94.4 million, respectively, related to CCJVs. Our access to joint venture cash may be limited by the provisions of the joint venture agreements. In connection with the acquisition of Layne, we acquired restricted cash that consists of escrow funds and judicial deposits associated with tax related legal proceedings in Latin America. Of the total balance, $4.3 million is included in other current assets and the remainder is included in other noncurrent assets in the consolidated balance sheets .

| Contract Assets | Contract Assets: Our contract assets include amounts due under contractual retainage provisions as well as costs and estimated earnings in excess of billings. Costs and estimated earnings in excess of billings also represent amounts earned and reimbursable under contracts, including customer affirmative claim recovery estimates, but have a conditional right for billing and payment such as achievement of milestones or completion of the project. With the exception of customer affirmative claims, generally, such unbilled amounts will become billable according to the contract terms and generally will be billed and collected over the next twelve months. Settlement with the customer of outstanding affirmative claims is dependent on the claims resolution process and could extend beyond one year. Based on our historical experience, we generally consider the collection risk related to billable amounts to be low. When events or conditions indicate that it is probable that the amounts outstanding become unbillable, the transaction price and associated contract asset is reduced. |
| Marketable Securities | Marketable Securities : We determine the classification of our marketable securities at the time of purchase and re-evaluate these determinations at each balance sheet date. Our marketable securities are fixed income marketable securities and are classified as held-to-maturity as we have the positive intent and ability to hold the securities to maturity. Held-to-maturity investments are stated at amortized cost and are periodically assessed for other-than-temporary impairment. Amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity, and is included in interest income. The cost of securities redeemed or called is based on the specific identification method. |
| Derivative Instruments | Derivative Instruments: We recognize derivative instruments as either assets or liabilities in the consolidated balance sheets at fair value using Level 2 inputs. To receive hedge accounting treatment, derivative instruments that are designated as cash flow hedges must be highly effective in offsetting changes to expected future cash flows on hedged transactions. The effective portion of the gain or loss on cash flow hedges is reported as a component of accumulated other comprehensive income (loss) and subsequently reclassified to interest expense in the consolidated statements of operations when the periodic hedged cash flows are settled. Adjustments to fair value on derivative instruments that do not qualify for hedge accounting treatment are reported through other income, net in the consolidated statements of operations. We do not enter into derivative instruments for speculative or trading purposes. |
| Fair Value of Financial Assets and Liabilities | Fair Value of Financial Assets and Liabilities: We measure and disclose certain financial assets and liabilities at fair value. ASC Topic 820, defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC Topic 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: Level 1 - Quoted prices in active markets for identical assets or liabilities. Level 2 - Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. We utilize the active market approach to measure fair value for our financial assets and liabilities. We report separately each class of assets and liabilities measured at fair value on a recurring basis and include assets and liabilities that are disclosed but not recorded at fair value in the fair value hierarchy. The carrying value of marketable securities approximates their fair value as determined by market quotes. Rates currently available to us for debt with similar terms and remaining maturities are used to estimate the fair value of existing debt. The carrying value of receivables and other amounts arising out of normal contract activities, including retentions, which may be settled beyond one year, is estimated to approximate fair value. |
| Concentrations Of Credit Risk And Other Risks | Concentrations of Credit Risk and Other Risks: Financial instruments, which potentially subject us to concentrations of credit risk, consist primarily of cash and cash equivalents, short-term and long-term marketable securities, and accounts receivable. We maintain our cash and cash equivalents and our marketable securities with several financial institutions. We invest with high credit quality financial institutions and, by policy, limit the amount of credit exposure to any one financial institution. Our receivables are from customers concentrated in the United States and we had $7.1 million receivables from foreign operations as of December 31, 2018. Receivables from foreign operations were immaterial as of December 31, 2017. We perform ongoing credit evaluations of our customers and generally do not require collateral, although the law provides us the ability to file mechanics’ liens on real property improved for private customers in the event of non-payment by such customers. We maintain an allowance for doubtful accounts which has historically been within management’s estimates. |
| Foreign Currency Transactions and Translations | Foreign Currency Transactions and Translation: Through the acquisitions of Layne and LiquiForce, we now have operations in Latin America (primarily Mexico) and Canada which involve exposure to possible volatile movements in foreign currency exchange rates. We account for foreign currency exchange transactions and translation in accordance with ASC Topic 830, In Mexico, most of our customer contracts and a significant portion of our costs are denominated in U.S. dollars; therefore, the functional currency is U.S. dollars. In Canada and Brazil, the functional currency is the local currency. Foreign currency transactions are translated into the functional currency with gains and losses included in other income, net in the consolidated statements of operations. The impact from foreign currency transactions was immaterial for 2018 Assets and liabilities in functional currency are translated into U.S. dollars at exchange rates prevailing at the balance sheet date. Revenues and expenses are translated into U.S. dollars at average foreign currency exchange rates prevailing during the reporting periods. The translation adjustments from functional currency to U.S. dollars are reported in accumulated other comprehensive (loss) income on the consolidated balance sheets. |
| Inventories | Inventories consist primarily of quarry products, contract-specific materials, water well drilling materials, and sewer remediation materials that are located in the U.S. and mineral extraction and drilling supplies located in the U.S. and Latin America. Cost of inventories are valued at the lower of average cost or net realizable value We reserve quarry products December 31, 2018 |
| Assets Held for Sale | Assets Held for Sale: During the three months ended September 30, 2018 , management approved the plan to sell certain non-core assets and the associated liabilities related to the water delivery business within our Water and Mineral Services operating group. The sale of the assets was completed during the fourth quarter of 2018. |
| Investments in Affiliates | Investments in Affiliates : Each investment accounted for under the equity method of accounting is reviewed for impairment in accordance with ASC Topic 323, Our investments in affiliates include foreign entities, real estate entities and an asphalt terminal entity. These investments are evaluated for impairment using the other-than-temporary impairment model, which requires an impairment charge to be recognized if our investment’s carrying amount exceeds its fair value, and the decline in fair value is deemed to be other than temporary. Recoverability is measured by comparison of net book values to future undiscounted cash flows the investments are expected to generate. Events or changes in circumstances, which would cause us to review undiscounted future cash flows include, but are not limited to:
•
significant adverse changes in legal factors or the business climate; and
•
current period cash flow or operating losses combined with a history of losses, or a forecast of continuing losses associated with the use of the asset. In addition, events or changes in circumstances specifically related to our real estate entities, include:
•
significant decreases in the market price of the asset;
•
accumulation of costs significantly in excess of the amount originally expected for the acquisition, development or construction of the asset; and
•
significant changes to the development or business plans of a project. Future undiscounted cash flows and fair value assessments for our foreign entities and the asphalt terminal entity are estimated based on market conditions and the political climate. Future undiscounted cash flows and fair value assessments for our real estate entities are estimated based on entitlement status, market conditions, and cost of construction, debt load, development schedules, status of joint venture partners and other factors applicable to the specific project. Fair value is estimated based on the expected future cash flows attributable to the asset or group of assets and on other assumptions that market participants would use in determining fair value, such as market discount rates, transaction prices for other comparable assets, and other market data. Our estimates of cash flows may differ from actual cash flows due to, among other things, fluctuations in interest rates, decisions made by jurisdictional agencies, economic conditions, or changes to our business operations. |
| Property and Equipment | Property and Equipment : Property and equipment are stated at cost. Depreciation for construction and other equipment is primarily provided using accelerated methods over lives ranging from eighteen months to seven years, and the straight-line method over lives from three to twenty years for the remaining depreciable assets. We believe that accelerated methods best approximate the service provided by the construction and other equipment. Depletion of quarry property is based on the usage of depletable reserves. We frequently sell property and equipment that has reached the end of its useful life or no longer meets our needs, including depleted quarry property. At the time that an asset or an asset group meets the held-for-sale criteria as defined by ASC Topic 360, we write it down to fair value less cost to sell, if the fair value is below the carrying value. Fair value is estimated by a variety of factors including, but not limited to, market comparative data, historical sales prices, broker quotes and third-party valuations. If material, such property is separately disclosed, otherwise it is held in property and equipment until sold. The cost and accumulated depreciation or depletion of property sold or retired is removed from the consolidated balance sheet and the resulting gains or losses, if any, are reflected in operating income on the consolidated statement of operations for the period. In the case that we abandon an asset, an amount equal to the carrying amount of the asset, less salvage value, if any, will be recognized as expense in the period that the asset was abandoned. Repairs and maintenance are expensed as incurred. Costs related to the development of internal-use software during the preliminary project and post-implementation stages are expensed as incurred. Costs incurred during the application development stage are capitalized. These costs consist primarily of software, hardware and consulting fees, as well as salaries and related costs. Amounts capitalized are reported as a component of office furniture and equipment within property and equipment. Capitalized software costs are depreciated using the straight-line method over the estimated useful life of the related software, which range from three to seven years. During the years ended December 31, 2018, 2017 and 2016, we capitalized $4.4 million, $7.9 million and $6.6 million, respectively, of internal-use software development and related hardware costs. |
| Long-lived Assets | Long-lived Assets: We review property and equipment and amortizable intangible assets for impairment at an asset group level whenever events or changes in circumstances indicate the net book value of an asset group may not be recoverable. Recoverability of these asset groups is measured by comparison of their net book values to the future undiscounted cash flows the asset groups are expected to generate. If the asset groups are considered to be impaired, an impairment charge will be recognized equal to the amount by which the net book value of the asset group exceeds fair value. We group construction and plant equipment assets at the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets. When an individual asset or group of assets is determined to no longer contribute to its vertically integrated construction and plant equipment asset group, it is assessed for impairment independently. As of December 31, 2018, amortizable intangible assets, which include customer relationships, developed technologies, permits, trademarks/trade names, backlog, favorable contracts and covenants not to compete, are being amortized over remaining terms from one to twenty years. As of December 31, 2018, amortizable intangible liabilities, which include unfavorable contracts and leases, are being amortized over remaining terms of two years. All intangible assets and liabilities are amortized on a straight-line basis except for backlog, favorable contracts and unfavorable contracts which will be amortized as the associated projects progress, and customer relationships which will be amortized using an accelerated method. |
| Goodwill | Goodwill: As a result of the change in our reportable segments, we reassessed our reporting units and have determined we have eight reporting units in which goodwill was recorded as follows:
•
Midwest Group Transportation
•
Midwest Group Specialty
•
Northwest Group Transportation
•
Northwest Group Materials
•
California Group Transportation
•
Water and Mineral Services Group Water
•
Water and Mineral Services Group Specialty
•
Water and Mineral Services Group Materials Goodwill was reallocated to these reporting units based on their relative fair values. See Note 13 for the goodwill balance by reportable segment as of December 31, 2018 and 2017. We perform our goodwill impairment tests annually as of November 1 and more frequently when events and circumstances occur that indicate a possible impairment of goodwill. Examples of such events or circumstances include, but are not limited to, the following:
•
a significant adverse change in legal factors or in the business climate;
•
an adverse action or assessment by a regulator;
•
a more likely than not expectation that a segment or a significant portion thereof will be sold; or
•
the testing for recoverability of a significant asset group within the segment. In performing the quantitative goodwill impairment tests, we calculate the estimated fair value of the reporting unit in which the goodwill is recorded using the discounted cash flows and market multiple methods. Judgments inherent in these methods include the determination of appropriate discount rates, the amount and timing of expected future cash flows and growth rates, and appropriate benchmark companies. The cash flows used in our 2018 discounted cash flow model were based on five-year financial forecasts, which in turn were based on the 2018-2022 operating plan developed internally by management adjusted for market participant-based assumptions. Our discount rate assumptions are based on an assessment of the equity cost of capital and appropriate capital structure for our reporting units. In assessing the reasonableness of our determined fair values of our reporting units, we evaluate the reasonableness of our results against our current market capitalization. The estimated fair value is compared to the net book value of the reporting unit, including goodwill. If the fair value of the reporting unit exceeds its net book value, goodwill of the reporting unit is considered not impaired. If the fair value of the reporting unit is less than its net book value, goodwill is impaired and the excess of the reporting unit’s net book value over the fair value is recognized as an impairment loss. During 2018, due to the change in reportable segments, the resulting change to reporting units and in accordance with ASC Topic 350, Intangibles - Goodwill and Other For our 2018 annual goodwill impairment test, we elected to perform a qualitative analysis and after assessing the totality of events and circumstances, we determined that it is more likely than not that the fair value of these reporting units were greater than the carrying amounts; therefore, a quantitative goodwill impairment test was not performed. |
| Contract Liabilities | Contract Liabilities: Our contract liabilities consist of provisions for losses, billings in excess of costs and estimated earnings and may include retainage. Provisions for losses are recognized in the consolidated statements of operations at the uncompleted performance obligation level for the amount of total estimated losses in the period that evidence indicates that the estimated total cost of a performance obligation exceeds its estimated total revenue. Billings in excess of costs and estimated earnings are billings to customers on contracts in advance of work performed, including advance payments negotiated as a contract condition. Generally, unearned project-related costs will be earned over the next twelve months. |
| Asset Reclamation Costs | Asset Retirement Obligations: We account for the costs related to legal obligations to reclaim aggregate mining sites and other facilities by recording our estimated asset retirement obligation at fair value using Level 3 inputs, capitalizing the estimated liability as part of the related asset’s carrying amount and allocating it to expense over the asset’s useful life. To determine the fair value of the obligation, we estimate the cost for a third-party to perform the legally required reclamation including a reasonable profit margin. This cost is then increased for future estimated inflation based on the estimated years to complete and discounted to fair value using present value techniques with a credit-adjusted, risk-free rate. In estimating the settlement date, we evaluate the current facts and conditions to determine the most likely settlement date. We review reclamation obligations at least annually for a revision to the cost or a change in the estimated settlement date. Additionally, reclamation obligations are reviewed in the period that a triggering event occurs that would result in either a revision to the cost or a change in the estimated settlement date. |
| Performance Guarantees and Warranties | Warranties: Many of our construction contracts contain warranty provisions covering defects in equipment, materials, design or workmanship that generally run from six months to one year after our customer accepts the contract. Because of the nature of our projects, including contract owner inspections of the work both during construction and prior to acceptance, we have not experienced material warranty costs for these short-term warranties and, therefore, do not believe an accrual for these costs is necessary. Certain construction contracts carry longer warranty periods, ranging from two to ten years, for which we have accrued an estimate of warranty cost. The warranty liability is estimated based on our experience with the type of work and any known risks relative to the project and was not material as of December 31, 2018 and 2017. Performance Guarantees: Agreements with our joint venture partners (“partner(s)”) for both construction joint ventures and line item joint ventures define each partner’s management role and financial responsibility in the project. The amount of operational exposure is generally limited to our stated ownership interest. However, due to the joint and several nature of the performance obligations under the related owner contracts, if one of the partners fails to perform, we and the remaining partners, if any, would be responsible for performance of the outstanding work (i.e., we provide a performance guarantee). We estimate our liability for performance guarantees for our unconsolidated construction joint ventures and line item joint ventures using estimated partner bond rates, which are Level 2 inputs, and include them in accrued expenses and other current liabilities (see Note 14) with a corresponding increase in equity in construction joint ventures in the consolidated balance sheets. We reassess our liability when and if changes in circumstances occur. The liability and corresponding asset are removed from the consolidated balance sheets upon customer acceptance of the project. Circumstances that could lead to a loss under these agreements beyond our stated ownership interest include the failure of a partner to contribute additional funds to the joint venture in the event the project incurs a loss or additional costs that we could incur should a partner fail to provide the services and resources that it had committed to provide in the agreement. |
| Accrued Insurance Costs | Accrued Insurance Costs: We carry insurance policies to cover various risks, primarily general liability, automobile liability, workers compensation and employee medical expenses, under which we are liable to reimburse the insurance company for a portion of each claim paid. The amounts for which we are liable for general liability and workers compensation generally range from the first $0.5 million to $1.0 million per occurrence. We accrue for probable losses, both reported and unreported, that are reasonably estimable using actuarial methods based on historic trends modified, if necessary, by recent events. Changes in our loss assumptions caused by changes in actual experience would affect our assessment of the ultimate liability and could have an effect on our operating results and financial position up to $1.0 million per occurrence for general liability and workers compensation or $0.3 million for medical insurance. |
| Contingencies | Contingencies: We are currently involved in various claims and legal proceedings. Loss contingency provisions are recorded if the potential loss from any asserted or un-asserted claim or legal proceeding is considered probable and the amount can be reasonably estimated. If a potential loss is considered probable but only a range of loss can be determined, the low-end of the range is recorded. These accruals represent management’s best estimate of probable loss. Disclosure is also provided when it is reasonably possible and estimable that a loss will be incurred or when it is reasonably possible that the amount of a loss will exceed the amount recorded. Significant judgment is required in both the determination of probability of loss and the determination as to whether an exposure is reasonably estimable. Because of uncertainties related to these matters, accruals are based only on the best information available at the time. As additional information becomes available, we reassess the potential liability related to claims and litigation and may revise our estimates. See Note 21 for additional information. |
| Stock-based Compensation | Stock-Based Compensation: We measure and recognize compensation expense, net of estimated forfeitures, over the requisite vesting periods for all stock-based payment awards made. Stock-based compensation is included in selling, general and administrative expenses and cost of revenue on our consolidated statements of operations. |
| Income Taxes | Income Taxes : Deferred taxes are provided on a liability method whereby deferred tax assets are recognized for deductible temporary differences and operating loss carry-forwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities in the consolidated financial statements and their respective tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. We report a liability in accrued expenses and other current liabilities and in other long-term liabilities in the consolidated balance sheets for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. We recognize interest and penalties, if any, related to unrecognized tax benefits in other (income) expense in the consolidated statements of operations. |
| Computation of Earnings Per Share | Computation of Earnings per Share : Basic net income per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted-average number of common shares and dilutive potential common shares outstanding during the period. Dilutive potential common shares include stock options and RSUs, under the 2012 Equity Incentive Plan. |
| Reclassifications | Reclassifications: Certain reclassifications of prior period amounts have been made to conform to the current period presentation. These reclassifications included $6.9 million and $9.2 million during 2017 and 2016, respectively, of cost of revenue and gross profit to the Materials segment primarily from the Transportation segment to better align costs with the respective segments These reclassifications had no impact on previously reported consolidated operating income or net income, on the consolidated balance sheets or on the statements of cash flows. |

We elected to apply Topic 606 to contracts with customers that are not substantially complete, i.e. less than 90% complete, as of January 1, 2018.The core principle of Topic 606 is that revenue will be recognized when promised goods or services are transferred to customers in an amount that reflects consideration for which entitlement is expected in exchange for those goods or services. While the adoption of Topic 606 did not have an impact on revenue of our Materials segment, it did impact revenue of our Transportation, Water and Specialty segments specifically in the following areas:
•
Multiple performance obligations – In accordance with Topic 606, we reviewed construction contracts with customers, including those related to contract modifications, to determine if there are multiple performance obligations. Based on this review, we identified one unconsolidated joint venture contract in our Transportation segment that has multiple performance obligations.
•
Multiple contracts – We reviewed contracts containing task orders and identified one master contract in our Water segment that consists of multiple individual contracts as defined by Topic 606. Previously, revenue for this contract was forecasted and recorded at the master contract level.
•
Revenue recognition – We identified one contract in our Specialty segment where performance obligations are satisfied and control of the promised goods and services are transferred to the customer upon delivery of goods rather than over time. Previously, revenue for this contract was recognized over time.
•
Provisions for losses – We identified one unconsolidated joint venture contract in our Transportation segment that has actual and provisions for losses at the performance obligation level related to completed and uncompleted performance obligations, respectively. Previously, provisions for losses were recorded at the contract level. The impact to retained earnings as of January 1, 2018 from the adoption of Topic 606 related to the items noted above was a net cumulative decrease of $15.2 million. In addition, as of January 1, 2018, we began to separately present contract assets and liabilities on the consolidated balance sheets. Contract assets include amounts due under contractual retainage provisions that were previously included in accounts receivable as well as costs and estimated earnings in excess of billings that were previously separately presented. Contract liabilities include billings in excess of costs and estimated earnings that were previously separately presented as well as provisions for losses that were previously included in accrued expenses and other current liabilities. See Note 6 for further information. Notes 4, 5 and 6 include information relating to our adoption of Topic 606. Note 4 includes information regarding our revenue disaggregated by operating group, Note 5 includes information regarding unearned revenue and Note 6 includes information regarding our contract assets and liabilities. The amounts by which each consolidated balance sheet line item as of December 31, 2018 and consolidated statement of operations line item for the year ended December 31, 2018 was affected by the adoption of Topic 606 relative to the previous revenue guidance are presented in the tables below (in thousands). The changes are primarily related to reclassifications on the consolidated balance sheet and the impact on the consolidated statement of operations from the new requirements under Topic 606. The change in retained earnings is net of the cumulative effect of initially applying Topic 606. December 31, 2018
