Basis Of Presentation [Abstract]
Basis Of Presentation	(1) Basis of Presentation The Condensed Consolidated Financial Statements do not include footnotes and certain financial information normally presented annually under generally accepted accounting principles in the United States (“GAAP”). Therefore, they should be read in conjunction with the audited consolidated financial statements and the related notes included in Tutor Perini Corporation’s (the “Company”) Annual Report on Form 10-K for the year ended December 31, 2019. The results of operations for the three and six months ended June 30, 2020 may not be indicative of the results that will be achieved for the full year ending December 31, 2020 . In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements reflect all adjustments, including those of a normal recurring nature, necessary to present fairly the Company’s consolidated financial position as of June 30, 2020 and its consolidated statements of operations and cash flows for the interim periods presented. Intercompany balances and transactions have been eliminated.

Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	(2) Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Measurement of Credit Losses on Financial Instruments , and issued subsequent amendments to the initial guidance within ASU 2019-04 and ASU 2019-05 (collectively, “ASU 2016-13”). The amendments in ASU 2016-13 replace the incurred loss impairment methodology with the current expected credit loss model, which requires consideration of a broader range of reasonable and supportable information to estimate credit losses. The Company adopted this ASU effective January 1, 2020. The adoption of ASU 2016-13 did not have a material impact on the Company’s financial position, results of operations or cash flows. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). The amendments in ASU 2020-04 provide temporary optional expedients and exceptions for applying GAAP to contract modifications, hedging relationships and other transactions to ease the potential accounting and financial reporting burden associated with transitioning away from reference rates that are expected to be discontinued, including the London Interbank Offered Rate (“LIBOR”). ASU 2020-04 is effective as of March 12, 2020 through December 31, 2022. The adoption of the new standard has not had and is not expected to have a material impact on the Company’s financial position, results of operations or cash flows. The following new accounting pronouncement requires implementation in future periods. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (“ASU 2019-12”), modifying Accounting Standards Codification (“ASC”) 740, Income Taxes (“ASC 740”). The amendments in ASU 2019-12, among other things, remove certain exceptions to the general principles in ASC 740 and seek more consistent application by clarifying and amending the existing guidance. ASU 2019-12 is effective for interim and annual reporting periods beginning after December 15, 2020. The Company is currently evaluating the new standard, which is not expected to have a material impact on the Company’s financial position, results of operations or cash flows.

Revenue was negatively impacted during the three- and six-month periods ended June 30, 2020 related to performance obligations satisfied (or partially satisfied) in prior periods by $ 19.8 million and $ 35.6 million, respectively. Likewise, revenue was negatively impacted during the three- and six-month periods ended June 30, 2019 related to performance obligations satisfied (or partially satisfied) in prior periods by $ 14.6 million and $ 27.7 million, respectively. Remaining Performance Obligations Remaining performance obligations represent the transaction price of firm orders for which work has not been performed and exclude unexercised contract options. As of June 30, 2020, the aggregate amounts of the transaction prices allocated to the remaining performance obligations of the Company’s construction contracts were $ 5.1 billion, $ 1.7 billion and $ 2.2 billion for the Civil, Building and Specialty Contractors segments, respectively. As of June 30, 2019, the aggregate amounts of the transaction prices allocated to the remaining performance obligations of the Company’s construction contracts were $ 5.5 billion, $ 1.7 billion and $ 2.2 billion for the Civil, Building and Specialty Contractors segments, respectively. The Company typically recognizes revenue on Civil segment projects over a period of three to five years , whereas for projects in the Building and Specialty Contractors segments, the Company typically recognizes revenue over a period of one to three years .

Contract Assets And Liabilities [Abstract]
Contract Assets And Liabilities	(4) Contract Assets and Liabilities The Company classifies contract assets and liabilities that may be settled beyond one year from the balance sheet date as current, consistent with the length of time of the Company’s project operating cycle. Contract assets include amounts due under retainage provisions, costs and estimated earnings in excess of billings and capitalized contract costs. The amounts as included on the Condensed Consolidated Balance Sheets consisted of the following: As of June 30, As of December 31, (in thousands) 2020 2019 Retainage receivable $ 581,495 $ 562,375 Costs and estimated earnings in excess of billings: Claims 729,170 705,993 Unapproved change orders 348,043 362,264 Other unbilled costs and profits 71,890 55,287 Total costs and estimated earnings in excess of billings 1,149,103 1,123,544 Capitalized contract costs 88,185 80,294 Total contract assets $ 1,818,783 $ 1,766,213 Retainage receivable represents amounts invoiced to customers where payments have been partially withheld pending the completion of certain milestones, satisfaction of other contractual conditions or the completion of the project. Retainage agreements vary from project to project, and balances could be outstanding for several months or years depending on a number of circumstances such as contract-specific terms, project performance and other variables that may arise as the Company makes progress toward completion. Costs and estimated earnings in excess of billings represent the excess of contract costs and profits (or contract revenue) over the amount of contract billings to date and are classified as a current asset. Costs and estimated earnings in excess of billings result when either: (1) the appropriate contract revenue amount has been recognized over time in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”) , but a portion of the revenue recorded cannot be billed currently due to the billing terms defined in the contract, or (2) costs are incurred related to certain claims and unapproved change orders. Claims occur when there is a dispute regarding both a change in the scope of work and the price associated with that change. Unapproved change orders occur when a change in the scope of work results in additional work being performed before the parties have agreed on the corresponding change in the contract price. The Company routinely estimates recovery related to claims and unapproved change orders as a form of variable consideration at the most likely amount it expects to receive and to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Claims and unapproved change orders are billable upon the agreement and resolution between the contractual parties and after the execution of contractual amendments. Increases in claims and unapproved change orders typically result from costs being incurred against existing or new positions; decreases normally result from resolutions and subsequent billings. As discussed in Note 11, the resolution of these claims and unapproved change orders may require litigation or other forms of dispute resolution proceedings. Other unbilled costs and profits are billable in accordance with the billing terms of each of the existing contractual arrangements and, as such, the timing of contract billing cycles can cause fluctuations in the balance of unbilled costs and profits. Ultimate resolution of other unbilled costs and profits typically involves incremental progress toward contractual requirements or milestones. Capitalized contract costs primarily represent costs to fulfill a contract that (1) directly relate to an existing or anticipated contract, (2) generate or enhance resources that will be used in satisfying performance obligations in the future and (3) are expected to be recovered through the contract, and are included in other current assets. Capitalized contract costs are generally expensed to the associated contract over the period of anticipated use on the project. During the three and six months ended June 30, 2020, $ 12.5 million and $ 22.8 million, respectively, of previously capitalized contract costs were amortized and recognized as expense on the related contracts. During the three and six months ended June 30, 2019, $ 8.6 million and $ 14.3 million, respectively, of previously capitalized contract costs were amortized and recognized as expense on the related contracts. Contract liabilities include amounts owed under retainage provisions and billings in excess of costs and estimated earnings. The amount as reported on the Condensed Consolidated Balance Sheets consisted of the following: As of June 30, As of December 31, (in thousands) 2020 2019 Retainage payable $ 278,045 $ 252,181 Billings in excess of costs and estimated earnings 962,446 844,389 Total contract liabilities $ 1,240,491 $ 1,096,570 Retainage payable represents amounts invoiced to the Company by subcontractors where payments have been partially withheld pending the completion of certain milestones, other contractual conditions or upon the completion of the project. Generally, retainage payable is not remitted to subcontractors until the associated retainage receivable from customers is collected. Billings in excess of costs and estimated earnings represent the excess of contract billings to date over the amount of contract costs and profits (or contract revenue) recognized to date. The balance may fluctuate depending on the timing of contract billings and the recognition of contract revenue. Revenue recognized during the three and six months ended June 30, 2020 and included in the opening billings in excess of costs and estimated earnings balances for each period totaled $ 470.8 million and $ 565.9 million, respectively. Revenue recognized during the three and six months ended June 30, 2019 and included in the opening billings in excess of costs and estimated earnings balances for each period totaled $ 289.4 million and $ 391.9 million, respectively.

Cash, Cash Equivalents And Restricted Cash	(5) Cash, Cash Equivalents and Restricted Cash The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the Condensed Consolidated Balance Sheets to the amounts shown in the Condensed Consolidated Statements of Cash Flows: As of June 30, As of December 31, (in thousands) 2020 2019 Cash and cash equivalents available for general corporate purposes $ 57,651 $ 43,760 Joint venture cash and cash equivalents 124,948 149,925 Cash and cash equivalents 182,599 193,685 Restricted cash 8,892 8,416 Total cash, cash equivalents and restricted cash $ 191,491 $ 202,101 Cash equivalents include short-term, highly liquid investments with maturities of three months or less when acquired. Cash and cash equivalents consist of amounts available for the Company’s general purposes, the Company’s proportionate share of cash held by the Company’s unconsolidated joint ventures and 100% of amounts held by the Company’s consolidated joint ventures. In both cases, cash held by joint ventures is available only for joint venture-related uses, including future distributions to joint venture partners. Amounts included in restricted cash are primarily held as collateral to secure insurance-related contingent obligations, such as insurance claim deductibles, in lieu of letters of credit.

Earnings Per Common Share (EPS) [Abstract]
Earnings Per Common Share (EPS)	(6) Earnings Per Common Share (EPS) Basic EPS and diluted EPS are calculated by dividing net income attributable to Tutor Perini Corporation by the following: for basic EPS, the weighted-average number of common shares outstanding during the period; and for diluted EPS, the sum of the weighted-average number of both outstanding common shares and potentially dilutive securities, which for the Company can include restricted stock units, unexercised stock options and the Convertible Notes, as defined in Note 9. In accordance with ASC 260, Earnings Per Share , the settlement of the principal amount of the Convertible Notes has no impact on diluted EPS because the Company has the intent and ability to settle the principal amount in cash. See Note 9 for further discussion of the Convertible Notes. The Company calculates the effect of the potentially dilutive restricted stock units and stock options using the treasury stock method. Three Months Ended June 30, Six Months Ended June 30, (in thousands, except per common share data) 2020 2019 2020 2019 Net income (loss) attributable to Tutor Perini Corporation $ 18,709 $ ( 320,530 ) $ 36,080 $ ( 320,886 ) Weighted-average common shares outstanding, basic 50,667 50,224 50,502 50,161 Effect of dilutive restricted stock units and stock options 268 — 383 — Weighted-average common shares outstanding, diluted 50,935 50,224 50,885 50,161 Net income (loss) attributable to Tutor Perini Corporation per common share: Basic $ 0.37 $ ( 6.38 ) $ 0.71 $ ( 6.40 ) Diluted $ 0.37 $ ( 6.38 ) $ 0.71 $ ( 6.40 ) Anti-dilutive securities not included above 2,209 4,191 2,209 4,354 For the three and six months ended June 30, 2019, all outstanding restricted stock units and stock options were excluded from the calculation of weighted-average diluted shares outstanding due to the net loss for the period.

Income Taxes

Income Taxes [Abstract]
Income Taxes	(7) Income Taxes The Company’s effective income tax rate was 23.7 % and 20.5 % for the three and six months ended June 30, 2020, respectively. The effective income tax rate for the six months ended June 30, 2020 primarily reflects the favorable impact of the 2019 net operating loss (“NOL”), which is allowed to be carried back up to five years as a result of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), enacted on March 27, 2020. Under the CARES Act, the Company’s NOL generated in 2019 may be carried back to tax years when the federal statutory tax rate was 35 % rather than the current rate of 21 %, consequently generating a larger tax benefit from the NOL due to the enactment of the CARES Act. The favorable impact resulting from the enactment of the CARES Act was partially offset by the unfavorable impact of the vesting of restricted stock units for which a large portion of the share-based compensation expense recognized in prior periods will not be deductible for income tax purposes. For the three and six months ended June 30, 2020, the effective income tax rates differed from the federal statutory rate also as a result of state income taxes, with the increases partially offset by earnings attributable to noncontrolling interests for which income taxes are not the responsibility of the Company. For the three and six months ended June 30, 2019, the Company recognized income tax benefits of $ 42.9 million and $ 40.7 million, with effective income tax rates of 12.0 % and 11.6 %, respectively. The Company’s provisions for income taxes and effective tax rates for the three and six months ended June 30, 2019 were significantly impacted by the goodwill impairment charge of $ 379.9 million. Of the total goodwill impairment charge, approximately $ 209.5 million pertained to goodwill that was not tax deductible and yielded permanent differences between book income and taxable income. The Company recognized a tax benefit totaling $ 50.4 million as a result of the impairment charge. The adjusted effective income tax rates, which exclude the tax benefit resulting from the goodwill impairment charge, were 34.7 % and 34.0 % for the three and six months ended June 30, 2019, respectively, and primarily reflected the unfavorable impact of expired stock options for which the share-based compensation expense recognized in prior periods will not be deductible for income taxes. For the three and six months ended June 30, 2019, the adjusted effective income tax rates were higher than the federal statutory rate also as a result of state income taxes, with the increases partially offset by earnings attributable to noncontrolling interests for which income taxes are not the responsibility of the Company.

Goodwill And Intangible Assets [Abstract]
Goodwill and Intangible Assets	(8) Goodwill and Intangible Assets Goodwill The following table presents the changes in the carrying amount of goodwill since its inception through June 30, 2020: Specialty (in thousands) Civil Building Contractors Total Gross goodwill $ 492,074 $ 424,724 $ 156,193 $ 1,072,991 Accumulated impairment ( 286,931 ) ( 424,724 ) ( 156,193 ) ( 867,848 ) Balance as of December 31, 2019 205,143 — — 205,143 Current year activity — — — — Balance as of June 30, 2020 $ 205,143 $ — $ — $ 205,143 The Company tests the goodwill allocated to its reporting units for impairment annually on October 1, or more frequently if events or circumstances indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The Company performed its annual impairment test in the fourth quarter of 2019 using a weighted-average of an income and a market approach. These approaches utilize various valuation assumptions, and small changes to the assumptions could have a significant impact on the concluded fair value. Based on this assessment, the Company concluded goodwill was no t impaired since the estimated fair value of the Civil reporting unit exceeded its carrying value. In addition, the Company determined that no triggering events occurred and no circumstances changed since the date of our annual impairment test that would more likely than not reduce the fair value of the Civil reporting unit below its carrying amount. During the first half of 2020, the novel coronavirus (“COVID-19”) pandemic, as well as the actions taken to contain and mitigate its public health effects, caused disruptions in domestic and global economies and financial markets. The vast majority of the Company’s projects, especially in its Civil reporting unit, have been designated as essential business, which allows the Company to continue its work on those projects. As such, the Civil reporting unit’s operations were not materially impacted during the three and six months ended June 30, 2020. However, due to the fluidity of the pandemic, uncertainties as to its scope and duration, and ongoing changes in the way that governments, businesses and individuals react and respond to the COVID-19 pandemic, the Company is unable at this time to accurately predict the pandemic’s future impact on the Company’s business, financial condition or performance. Among other things, governments could prohibit the continuation of certain projects that to date have been designated as “essential” or could impose health, safety and other operational requirements on such projects that could result in delays to or suspensions of such projects. In addition, employees and contractors working on such projects could be unable or unwilling to continue working on them, perhaps for extended periods. The COVID-19 pandemic also could negatively affect the ability of counterparties or joint venture partners to make required payments on a timely basis or at all. The Company will continue to monitor events and circumstances for changes that indicate the Civil reporting unit goodwill would need to be reevaluated for impairment during future interim periods prior to the annual impairment test. These future events and circumstances include, but are not limited to, changes in the overall financial performance of the Civil reporting unit, impacts to our business as a result of the COVID-19 pandemic, as well as other quantitative and qualitative factors which could indicate potential triggering events for possible impairment. Intangible Assets Intangible assets consist of the following: As of June 30, 2020 Weighted Accumulated Average Accumulated Impairment Carrying Amortization (in thousands) Cost Amortization Charge Value Period Trade names (non-amortizable) $ 117,600 $ — $ ( 67,190 ) $ 50,410 Indefinite Trade names (amortizable) 74,350 ( 22,511 ) ( 23,232 ) 28,607 20 years Contractor license 6,000 — ( 6,000 ) — N/A Customer relationships 39,800 ( 21,575 ) ( 16,645 ) 1,580 12 years Construction contract backlog 149,290 ( 89,213 ) — 60,077 3 years Total $ 387,040 $ ( 133,299 ) $ ( 113,067 ) $ 140,674 As of December 31, 2019 Weighted Accumulated Average Accumulated Impairment Carrying Amortization (in thousands) Cost Amortization Charge Value Period Trade names (non-amortizable) $ 117,600 $ — $ ( 67,190 ) $ 50,410 Indefinite Trade names (amortizable) 74,350 ( 21,267 ) ( 23,232 ) 29,851 20 years Contractor license 6,000 — ( 6,000 ) — N/A Customer relationships 39,800 ( 21,048 ) ( 16,645 ) 2,107 12 years Construction contract backlog 149,290 ( 76,388 ) — 72,902 3 years Total $ 387,040 $ ( 118,703 ) $ ( 113,067 ) $ 155,270 Amortization expense for the three and six months ended June 30, 2020 was $ 8.8 million and $ 14.6 million, respectively. Amortization expense for the three and six months ended June 30, 2019 was $ 0.9 million and $ 1.8 million, respectively. As of June 30, 2020, amortization expense is estimated to be $ 19.5 million for the remainder of 2020, $ 26.4 million in 2021, $ 22.0 million in 2022 and $ 2.5 million per year for the years 2023 through 2025. The Company performed an annual impairment assessment of its non-amortizable trade names in the fourth quarter of 2019 using a qualitative approach to determine whether conditions existed to indicate that it was more likely than not that the fair value of non-amortizable trade names is less than their carrying values. Based on this assessment, the Company concluded that it was more likely than not that the fair value of the non-amortizable trade names was greater than their carrying values, and therefore a quantitative analysis was not required. In addition, no triggering events occurred and no circumstances changed since the date of our annual impairment test that would indicate impairment of the Company’s non-amortizable trade names.

Interest on the 2017 Senior Notes is payable in arrears semi-annually in May and November of each year, beginning in November 2017. Prior to May 1, 2020, the Company could have redeemed the 2017 Senior Notes at a redemption price equal to 100 % of their principal amount plus a “make-whole” premium described in the indenture. In addition, prior to May 1, 2020, the Company also could have redeemed up to 40 % of the original aggregate principal amount of the notes at a redemption price of 106.875 % of their principal amount with the proceeds received by the Company from any offering of the Company’s equity. Since May 1, 2020, the Company may redeem the 2017 Senior Notes at specified redemption prices described in the indenture. Upon a change of control, holders of the 2017 Senior Notes may require the Company to repurchase all or part of the 2017 Senior Notes at 101 % of the principal amount thereof, plus accrued and unpaid interest to the redemption date. The 2017 Senior Notes are senior unsecured obligations of the Company and are guaranteed by substantially all of the Company’s existing and future subsidiaries that also guarantee obligations under the Company’s 2017 Credit Facility, as defined below. In addition, the indenture for the 2017 Senior Notes provides for customary covenants, including events of default and restrictions on the payment of dividends and share repurchases. 2017 Credit Facility On April 20, 2017, the Company entered into a credit agreement (the “2017 Credit Facility”) with SunTrust Bank, now known as Truist Bank, as Administrative Agent, Swing Line Lender and L/C Issuer and a syndicate of other lenders. The 2017 Credit Facility provides for a $ 350 million revolving credit facility (the “2017 Revolver”) and a sublimit for the issuance of letters of credit and swingline loans up to the aggregate amount of $ 150 million and $ 10 million, respectively, both maturing on April 20, 2022 unless any of the Convertible Notes, as defined below, are outstanding on December 17, 2020, in which case all such borrowings will mature on December 17, 2020 (the “spring-forward provision”), provided however (i) if the Convertible Notes are refinanced in full with the proceeds of permitted refinancing indebtedness in accordance with the terms of the 2017 Credit Facility, the maturity date for the 2017 Credit Facility will remain April 20, 2022 and (ii) if the Company issues “New Convertible Notes” (as defined in the 2017 Credit Facility) and retires the Convertible Notes in full, the maturity date for the 2017 Credit Facility will be the earlier of (x) April 20, 2022 or (y) 90 days prior to the maturity date for such New Convertible Notes. The 2017 Credit Facility also permits additional borrowings in an aggregate amount of $ 150 million, which can be in the form of increased capacity on the 2017 Revolver or the establishment of one or more term loans. Borrowings under the 2017 Revolver bear interest, at the Company’s option, at a rate equal to (a) LIBOR plus a margin of between 1.50 % and 3.00 % or (b) a base rate (determined by reference to the highest of (i) the administrative agent’s prime lending rate, (ii) the federal funds effective rate plus 50 basis points, (iii) the LIBOR rate for a one-month interest period plus 100 basis points and (iv) 0 %), plus a margin of between 0.50 % and 2.00 %, in each case based on the Consolidated Leverage Ratio (as defined in the 2017 Credit Facility). In addition to paying interest on outstanding principal under the 2017 Credit Facility, the Company will pay a commitment fee to the lenders under the 2017 Revolver in respect of the unutilized commitments thereunder. The Company will pay customary letter of credit fees. If an event of default occurs and is continuing, the otherwise applicable margin and letter of credit fees will be increased 2 % per annum. The weighted-average annual interest rate on borrowings under the 2017 Revolver was approximately 3.66 % during the six months ended June 30, 2020. The 2017 Credit Facility contains customary covenants for credit facilities of this type, including maximum consolidated leverage ratios ranging from 4.00 :1.00 to 3.25 :1.00 over the life of the facility and a minimum consolidated fixed charge coverage ratio of 1.25 :1.00. On May 7, 2019, certain provisions of the 2017 Credit Facility were amended, including setting the maximum leverage ratio at 3.50 :1.00 for the remainder of its term, thus eliminating the step down from 3.50 :1:00 to 3.25 :1.00. Substantially all of the Company’s subsidiaries unconditionally guarantee the obligations of the Company under the 2017 Credit Facility; additionally, the obligations are secured by a lien on all personal property of the Company and its subsidiaries guaranteeing these obligations. As of June 30, 2020, there was $ 250 million available under the 2017 Revolver, and the Company had not utilized the 2017 Credit Facility for letters of credit. The Company was in compliance with the financial covenants under the 2017 Credit Facility as of June 30, 2020. As a result of the spring-forward provision mentioned above, the facility will mature on December 17, 2020 if the Convertible Notes remain outstanding at that time. The Company does not have call rights that allow it to unilaterally redeem the Convertible Notes. Due to the spring-forward provision in the 2017 Credit Facility, all borrowings under the facility are included in “Current maturities of long-term debt” on the Condensed Consolidated Balance Sheet as of June 30, 2020. The Company continues to evaluate options to address the spring-forward provision and refinancing or retirement of the outstanding Convertible Notes. Convertible Notes On June 15, 2016, the Company issued $ 200 million of 2.875 % Convertible Senior Notes due June 15, 2021 (the “Convertible Notes”) in a private placement offering. The Convertible Notes are unsecured obligations of the Company and do not contain any financial covenants or restrictions on the payments of dividends, the incurrence of indebtedness or the issuance or repurchase of securities by the Company. The Convertible Notes bear interest at a rate of 2.875 % per year, payable in cash semi-annually in June and December, and are included in “Current maturities of long-term debt” on the Condensed Consolidated Balance Sheet as of June 30, 2020. Prior to January 15, 2021, the Convertible Notes will be convertible only under the following circumstances: (1) during the five business day period after any ten consecutive trading day period in which the trading price per $ 1,000 principal amount of Convertible Notes for such trading day was less than 98 % of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; (2) if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130 % of the conversion rate of 33.0579 (or $ 39.32 ) on each applicable trading day; or (3) upon the occurrence of specified corporate events. On or after January 15, 2021 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their notes, in multiples of $ 1,000 principal amount, at the option of the holder regardless of the foregoing circumstances. The Convertible Notes will be convertible at an initial conversion rate of 33.0579 shares of the Company’s common stock per $ 1,000 principal amount of the Convertible Notes, which is equivalent to an initial conversion price of approximately $ 30.25 . The conversion rate will be subject to adjustment for some events but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date, the Company is required to increase, in certain circumstances, the conversion rate for a holder who elects to convert their Convertible Notes in connection with such a corporate event including customary conversion rate adjustments in connection with a “make-whole fundamental change” described in the indenture. Upon conversion, and at the Company’s election, the Company may satisfy its conversion obligation with cash, shares of its common stock or a combination thereof. As of June 30, 2020, the conversion provisions of the Convertible Notes have not been triggered. Interest Expense Interest expense as reported in the Condensed Consolidated Statements of Operations consisted of the following: Three Months Ended Six Months Ended June 30, June 30, (in thousands) 2020 2019 2020 2019 Cash interest expense: Interest on 2017 Senior Notes $ 8,593 $ 8,594 $ 17,187 $ 17,187 Interest on 2017 Credit Facility 2,338 3,682 4,753 6,327 Interest on Convertible Notes 1,438 1,438 2,875 2,875 Other interest 535 541 1,039 1,116 Total cash interest expense 12,904 14,255 25,854 27,505 Non-cash interest expense: (a) Amortization of discount and debt issuance costs on Convertible Notes 2,933 2,671 5,797 5,279 Amortization of debt issuance costs on 2017 Credit Facility 402 387 804 749 Amortization of debt issuance costs on 2017 Senior Notes 225 209 445 414 Total non-cash interest expense 3,560 3,267 7,046 6,442 Total interest expense $ 16,464 $ 17,522 $ 32,900 $ 33,947 ____________________________________________________________________________________________________ (a) The combination of cash and non-cash interest expense produces effective interest rates that are higher than contractual rates. Accordingly, the effective interest rates for the 2017 Senior Notes and the Convertible Notes were 7.13 % and 9.39 %, respectively, for the six months ended June 30, 2020.

Leases [Abstract]
Leases	(10) Leases The Company leases certain office space, construction and office equipment, vehicles and temporary housing generally under non-cancelable operating leases. Leases with an initial term of one year or less are not recorded on the balance sheet, and the Company generally recognizes lease expense for these leases on a straight-line basis over the lease term. As of June 30, 2020, the Company’s operating leases have remaining lease terms ranging from less than one year to 10 years, some of which include options to renew the leases. The exercise of lease renewal options is generally at the Company’s sole discretion. The Company’s leases do not contain any material residual value guarantees or material restrictive covenants. The following table presents components of lease expense for the three and six months ended June 30, 2020 and 2019: Three Months Ended Six Months Ended June 30, June 30, (in thousands) 2020 2019 2020 2019 Operating lease expense $ 3,661 $ 3,921 $ 7,428 $ 7,702 Short-term lease expense (a) 23,056 16,486 40,321 33,057 26,717 20,407 47,749 40,759 Less: Sublease income 329 262 658 521 Total lease expense $ 26,388 $ 20,145 $ 47,091 $ 40,238 ____________________________________________________________________________________________________ (a) Short-term lease expense includes all leases with lease terms ranging from less than one month to one year .

Commitments And Contingencies [Abstract]
Commitments And Contingencies	(11) Commitments and Contingencies The Company and certain of its subsidiaries are involved in litigation and other legal proceedings and forms of dispute resolution in the ordinary course of business, including but not limited to disputes over contract payment and/or performance-related issues (such as disagreements regarding delay or a change in the scope of work of a project and/or the price associated with that change) and other matters incidental to the Company’s business. In accordance with ASC 606, the Company makes assessments of these types of matters on a routine basis and, to the extent permitted by ASC 606, estimates and records recovery related to these matters as a form of variable consideration at the most likely amount the Company expects to receive, as discussed further in Note 4 . In addition, the Company is contingently liable for litigation, performance guarantees and other commitments arising in the ordinary course of business, which are accounted for in accordance with ASC 450, Contingencies . Management reviews these matters regularly and updates or revises its estimates as warranted by subsequent information and developments. These assessments require judgments concerning matters that are inherently uncertain, such as litigation developments and outcomes, the anticipated outcome of negotiations and the estimated cost of resolving disputes. Consequently, these assessments are estimates, and actual amounts may vary from such estimates. In addition, because such matters are typically resolved over long periods of time, the Company’s assets and liabilities may change over time should the circumstances dictate. The description of the legal proceedings listed below include management’s assessment of those proceedings. Management believes that, based on current information and discussions with the Company’s legal counsel, the ultimate resolution of other matters is not expected to have a material effect on the Company’s consolidated financial position, results of operations or cash flows. A description of the material pending legal proceedings, other than ordinary routine litigation incidental to the business is as follows: Five Star Electric Matter In the third quarter of 2015, Five Star Electric Corp. (“Five Star”), a wholly owned subsidiary of the Company that was acquired in 2011, entered into a tolling agreement (which has since expired) related to an ongoing investigation being conducted by the United States Attorney’s Office for the Eastern District of New York (“USAO EDNY”). Five Star has been cooperating with the USAO EDNY since late June 2014, when it was first made aware of the investigation, and has provided information requested by the government related to its use of certain minority-owned, women-owned, small and disadvantaged business enterprises and certain of Five Star’s employee compensation, benefit and tax practices. As of June 30, 2020, the Company cannot predict the ultimate outcome of the investigation and cannot reasonably estimate the potential loss or range of loss that Five Star or the Company may incur or the impact of the results of the investigation on Five Star or the Company. Alaskan Way Viaduct Matter In January 2011, Seattle Tunnel Partners (“STP”), a joint venture between Dragados USA, Inc. and the Company, entered into a design-build contract with the Washington State Department of Transportation (“WSDOT”) for the construction of a large-diameter bored tunnel in downtown Seattle, King County, Washington to replace the Alaskan Way Viaduct, also known as State Route 99. The Company has a 45 % interest in STP. The construction of the large-diameter bored tunnel required the use of a tunnel boring machine (“TBM”). In December 2013, the TBM struck a steel pipe, installed by WSDOT as a well casing for an exploratory well. The TBM was significantly damaged and was required to be repaired. STP has asserted that the steel pipe casing was a differing site condition that WSDOT failed to properly disclose. The Disputes Review Board mandated by the contract to hear disputes issued a decision finding the steel casing was a Type I (material) differing site condition. WSDOT did not accept that finding. The TBM was insured under a Builder’s Risk Insurance Policy (the “Policy”) with Great Lakes Reinsurance (UK) PLC and a consortium of other insurers (the “Insurers”). STP submitted the claims to the Insurers and requested interim payments under the Policy. The Insurers refused to pay and denied coverage. In June 2015, STP filed a lawsuit in the King County Superior Court, State of Washington seeking declaratory relief concerning contract interpretation, as well as damages as a result of the Insurers’ breach of their obligations under the terms of the Policy. STP is also asserting extra-contractual and statutory claims against the Insurers. WSDOT is deemed a plaintiff since WSDOT is an insured under the Policy and had filed its own claim for damages. Hitachi Zosen (“Hitachi”), the manufacturer of the TBM, joined the case as a plaintiff for costs incurred to repair the damages to the TBM. In September 2018, rulings received on pre-trial motions effectively limited potential recovery under the Policy for STP, WSDOT and Hitachi. However, on December 19, 2018, the Court of Appeal granted the Company’s request for a discretionary appeal of those rulings. The appeal is expected to be heard in late 2020. STP submitted damages to the Insurers in the King County lawsuit in the amount of $ 532 million. STP also sought these damages from WSDOT related to the pipe-strike by the TBM in a related lawsuit in Thurston County (see following paragraph). In March 2016, WSDOT filed a complaint against STP in Thurston County Superior Court alleging breach of contract, seeking $ 57.2 million in delay-related damages and seeking declaratory relief concerning contract interpretation. STP filed its answer to WSDOT’s complaint and filed a counterclaim against WSDOT and Hitachi, as the TBM designer, seeking damages of $ 667 million. On October 3, 2019, STP and Hitachi entered into a settlement agreement which released and dismissed the claims that STP and Hitachi had against each other. The jury trial between STP and WSDOT commenced on October 7, 2019 and concluded on December 13, 2019, with a jury verdict in favor of WSDOT awarding them $ 57.2 million in damages. Judgment was entered on January 10, 2020, and a notice of appeal was filed by STP on January 17, 2020. The appeal is expected to be heard in 2021. The Company recorded the impact of the jury verdict during the fourth quarter of 2019, resulting in a pre-tax charge of $ 166.8 million. The charge includes a pre-tax accrual of $ 25.7 million (which is the Company’s 45 % proportionate share of the $ 57.2 million in damages awarded by the jury to WSDOT). Payment of damages will only be made if the adverse verdict is upheld on appeal, as the payment is secured by a bond for the course of the appeal. Other than the possible future payment in cash of $ 25.7 million in damages, the charge is for non-cash write-downs primarily related to the costs and estimated earnings in excess of billings and receivables that the Company previously recorded to reflect its expected recovery in this case. With respect to STP’s direct and indirect claims against the Insurers, management has included in receivables an estimate of the total anticipated recovery concluded to be probable. George Washington Bridge Bus Station Matter In August 2013, Tutor Perini Building Corporation (“TPBC”) entered into a contract with the George Washington Bridge Bus Station Development Venture, LLC (the “Developer”) to renovate the George Washington Bridge Bus Station, a mixed-use facility owned by the Port Authority of New York and New Jersey (the “Port Authority”) that serves as a transit facility and retail space. The $ 100 million project experienced significant design errors and associated delays, resulting in damages to TPBC and its subcontractors, including WDF and Five Star, wholly owned subsidiaries of the Company. The project reached substantial completion on May 16, 2017. On February 26, 2015, the Developer filed a demand for arbitration, subsequently amended, seeking $ 30 million in alleged damages and declaratory relief that TPBC’s requests for additional compensation are invalid due to lack of notice. TPBC denied the Developer’s claims and filed a counterclaim in March 2018. TPBC seeks in excess of $ 113 million in the arbitration, which includes unpaid contract balance claims, the return of $ 29 million retained by the Developer in alleged damages, as well as extra work claims, pass-through claims and delay claims. Hearings on the merits commenced on September 24, 2018 before the arbitration panel. On June 4, 2019, the arbitration panel, as confirmed by the U.S. District Court in the Southern District of New York, issued a writ of attachment for $ 23 million of the $ 29 million discussed above. On October 7, 2019, the Developer filed for bankruptcy protection in the Southern District of New York under Chapter 11 of the Bankruptcy Code. The filing for bankruptcy stayed the pending arbitration proceedings. TPBC appeared in the bankruptcy proceedings on October 8, 2019 and filed a Proof of Claim in the amount of $ 113 million on December 13, 2019. On June 5, 2020, the Developer, secured lenders and the Port Authority announced that they had reached a settlement of their disputes. As part of the settlement, the Port Authority waived the enforcement of its right to seek a “cure” pursuant to its lease agreement with the Developer which requires construction costs be paid prior to any sale of the leasehold, the sole asset in the Developer’s bankruptcy estate to be distributed in this bankruptcy. On July 14, 2020, the bankruptcy court conducted a hearing to determine (1) whether to approve the settlement agreement between the Developer, secured lenders and the Port Authority; and (2) whether TPBC can assert third-party beneficiary rights to the lease agreement and require that prior to the sale of the leasehold, any outstanding costs owed to contractors for the cost of building the project must be paid pursuant to the lease agreement’s “cure” provisions. At this hearing, the bankruptcy court indicated that it will issue a formal order approving the settlement and denying TPBC’s third-party beneficiary rights under the lease agreement. TPBC plans to appeal the decision, once it is formally issued, to challenge the denial of its third-party beneficiary rights under the lease agreement’s “cure” provisions and to avoid being subordinate to the claims of the secured lenders in the bankruptcy proceedings. Separately, on July 2, 2018, TPBC filed a lawsuit against the Port Authority, as owner of the project, and STV Incorporated, as designer, seeking the same $ 113 million in damages pursuant to the lease agreement between the Port Authority and the Developer. On August 20, 2018, the Port Authority filed a motion to dismiss, which was denied by the court on July 1, 2019. The Port Authority appealed this decision on July 15, 2019, and the appeal is expected to be decided in 2021. On December 2, 2019, the Court of Appeal denied the Port Authority’s request to stay the trial court action pending the appeal. As a result, the lawsuit is proceeding against the Port Authority before the trial court. On January 13, 2020, the court dismissed STV Incorporated from the case. On January 27, 2020, TPBC filed separate litigation in the U.S. District Court for the Southern District of New York in which TPBC asserted related claims against individual owners of the Developer for their wrongful conversion of project funds and against certain lenders that received interest payments from project funds and other amounts earmarked to pay the contractors. On June 1, 2020, the defendants filed motions to dismiss, and a decision remains pending from the court. As of June 30, 2020, the Company has concluded that the potential for a material adverse financial impact due to the Developer’s claims is remote. With respect to TPBC’s claims against the Developer, its owners and the Port Authority, management has made an estimate of the total anticipated recovery on this project, and such estimate is included in revenue recorded to date.

Share-Based Compensation [Abstract]
Share-Based Compensation	(12) Share-Based Compensation As of June 30, 2020, there were 1,185,089 shares of common stock available for grant under the Tutor Perini Corporation Omnibus Incentive Plan. During the first six months of 2020 and 2019, the Company granted the following share-based instruments: (1) restricted stock units totaling 75,000 and 175,000 with weighted-average fair values per share of $ 13.93 and $ 20.41 , respectively; (2) stock options totaling 75,000 and 85,000 with weighted-average fair values per share of $ 3.94 and $ 7.57 , respectively, and weighted-average per share exercise prices of $ 25.70 and $ 25.62 , respectively; and (3) unrestricted stock units totaling 194,177 and 98,591 with weighted-average fair values per share of $ 8.60 and $ 15.72 , respectively. During the six months ended June 30, 2019, 750,000 stock options with a weighted-average per share exercise price of $ 20.33 expired. The fair value of restricted and unrestricted stock units is based on the closing price of the Company’s common stock on the New York Stock Exchange on the date of the grant and the fair value of stock options is based on the Black-Scholes model. The fair value of stock options granted during the first six months of 2020 was determined using the Black-Scholes model based on the following weighted-average assumptions: (i) expected life of 6.0 years, (ii) expected volatility of 44.91 %, (iii) risk-free rate of 1.56 %, and (iv) no quarterly dividends. Certain performance-based awards contain market condition components and are valued on the date of grant using a Monte Carlo simulation model. For the three and six months ended June 30, 2020, the Company recognized, as part of general and administrative expenses, costs for share-based payment arrangements totaling $ 3.8 million and $ 8.3 million, respectively, and $ 4.6 million and $ 10.1 million for the three and six months ended June 30, 2019, respectively. As of June 30, 2020, the balance of unamortized share-based compensation expense was $ 14.8 million, which is expected to be recognized over a weighted-average period of 1.7 years.

Fair Value Measurements	(14) Fair Value Measurements The fair value hierarchy established by ASC 820, Fair Value Measurement , prioritizes the use of inputs used in valuation techniques into the following three levels:  Level 1 inputs are observable quoted prices in active markets for identical assets or liabilities  Level 2 inputs are observable, either directly or indirectly, but are not Level 1 inputs  Level 3 inputs are unobservable The following fair value hierarchy table presents the Company’s assets that are measured at fair value on a recurring basis as of June 30, 2020 and December 31, 2019: As of June 30, 2020 As of December 31, 2019 Fair Value Hierarchy Fair Value Hierarchy (in thousands) Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Cash and cash equivalents (a) $ 182,599 $ — $ — $ 182,599 $ 193,685 $ — $ — $ 193,685 Restricted cash (a) 8,892 — — 8,892 8,416 — — 8,416 Restricted investments (b) — 75,382 — 75,382 — 70,974 — 70,974 Investments in lieu of retainage (c) 98,837 1,208 — 100,045 89,572 1,219 — 90,791 Total $ 290,328 $ 76,590 $ — $ 366,918 $ 291,673 $ 72,193 $ — $ 363,866 ____________________________________________________________________________________________________ (a) Includes money market funds and short-term investments with maturity dates of three months or less when acquired. (b) Restricted investments, as of June 30, 2020, consist of investments in U.S. government agency securities of $ 37.5 million, corporate debt securities of $ 36.8 million and corporate certificates of deposits of $ 1.1 million with maturities of up to five years , and are valued based on pricing models, which are determined from a compilation of primarily observable market information, broker quotes in non-active markets or similar assets and are therefore classified as Level 2 assets. As of December 31, 2019, restricted investments consisted of investments in corporate debt securities of $ 35.8 million, U.S. government agency securities of $ 33.8 million and corporate certificates of deposits of $ 1.4 million with maturities of up to five years . The amortized cost of these available-for-sale securities at June 30, 2020 and December 31, 2019 was not materially different from the fair value. (c) Investments in lieu of retainage are included in retainage receivable and as of June 30, 2020 are comprised of money market funds of $ 98.8 million and municipal bonds of $ 1.2 million. The fair values of the money market funds are measured using quoted market prices; therefore, they are classified as Level 1 assets. The fair values of municipal bonds are measured using readily available pricing sources for comparable instruments; therefore, they are classified as Level 2 assets. As of December 31, 2019, investments in lieu of retainage consisted of money market funds of $ 89.6 million and municipal bonds of $ 1.2 million. The amortized cost of these available-for-sale securities at June 30, 2020 and December 31, 2019 was not materially different from the fair value. The carrying values of receivables, payables and other amounts arising out of normal contract activities, including retainage, which may be settled beyond one year, are estimated to approximate fair value. Of the Company’s long-term debt, the fair value of the 2017 Senior Notes was $ 484.4 million and $ 485.0 million as of June 30, 2020 and December 31, 2019, respectively. The fair value of the Convertible Notes was $ 190.7 million and $ 193.4 million as of June 30, 2020 and December 31, 2019, respectively. The fair values of the 2017 Senior Notes and Convertible Notes were determined using Level 1 inputs, specifically current observable market prices. The reported value of the Company’s remaining borrowings approximates fair value as of June 30, 2020 and December 31, 2019.

Variable Interest Entities [Abstract]
Variable Interest Entities	(15) Variable Interest Entities (VIEs) The Company may form joint ventures or partnerships with third parties for the execution of projects. In accordance with ASC 810, Consolidation (“ASC 810”), the Company assesses its partnerships and joint ventures at inception to determine if any meet the qualifications of a VIE. The Company considers a joint venture a VIE if either (a) the total equity investment is not sufficient to permit the entity to finance its activities without additional subordinated financial support, (b) characteristics of a controlling financial interest are missing (either the ability to make decisions through voting or other rights, the obligation to absorb the expected losses of the entity or the right to receive the expected residual returns of the entity), or (c) the voting rights of the equity holders are not proportional to their obligations to absorb the expected losses of the entity and/or their rights to receive the expected residual returns of the entity, and substantially all of the entity’s activities either involve or are conducted on behalf of an investor that has disproportionately few voting rights. Upon the occurrence of certain events outlined in ASC 810, the Company reassesses its initial determination of whether a joint venture is a VIE. ASC 810 also requires the Company to determine whether it is the primary beneficiary of the VIE. The Company concludes that it is the primary beneficiary and consolidates the VIE if the Company has both (a) the power to direct the economically significant activities of the VIE and (b) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. The Company considers the contractual agreements that define the ownership structure, distribution of profits and losses, risks, responsibilities, indebtedness, voting rights and board representation of the respective parties in determining if the Company is the primary beneficiary. The Company also considers all parties that have direct or implicit variable interests when determining whether it is the primary beneficiary. In accordance with ASC 810, management’s assessment of whether the Company is the primary beneficiary of a VIE is performed continuously. As of June 30, 2020, the Company had unconsolidated VIE-related current assets and liabilities of $ 3.4 million and $ 3.3 million, respectively, included in the Company’s Condensed Consolidated Balance Sheet. As of December 31, 2019, the Company had unconsolidated VIE-related current assets and liabilities of $ 1.5 million and $ 1.4 million, respectively, included in the Company’s Condensed Consolidated Balance Sheet. The Company’s maximum exposure to loss as a result of its investments in unconsolidated VIEs is typically limited to the aggregate of the carrying value of the investment and future funding commitments. There were no future funding requirements for the unconsolidated VIEs as of June 30, 2020. As of June 30, 2020, the Company’s Condensed Consolidated Balance Sheet included current and noncurrent assets of $ 401.1 million and $ 36.4 million, respectively, as well as current liabilities of $ 581.1 million related to the operations of its consolidated VIEs. As of December 31, 2019, the Company’s Condensed Consolidated Balance Sheet included current and noncurrent assets of $ 365.0 million and $ 52.0 million, respectively, as well as current liabilities of $ 556.1 million related to the operations of its consolidated VIEs. Below is a discussion of some of the Company’s more significant or unique VIEs. The Company established a joint venture to construct the Purple Line Extension Section 2 (Tunnels and Stations) and Section 3 (Stations) mass-transit projects in Los Angeles, California with a combined value of approximately $ 2.8 billion. The Company has a 75 % interest in the joint venture with the remaining 25 % held by O&G Industries, Inc. The joint venture was initially financed with contributions from the partners and, per the terms of the joint venture agreement, the partners may be required to provide additional capital contributions in the future. The Company has determined that this joint venture is a VIE for which the Company is the primary beneficiary. The Company also established a joint venture with Parsons Corporation (“Parsons”) to construct the Newark Liberty International Airport Terminal One project, a $ 1.4 billion transportation infrastructure project in Newark, New Jersey. The Company has an 80 % interest in the joint venture with the remaining 20 % held by Parsons. The joint venture was initially financed with contributions from the partners and, per the terms of the joint venture agreement, the partners may be required to provide additional capital contributions in the future. The Company has determined that this joint venture is a VIE for which the Company is the primary beneficiary.

Business Segments [Abstract]
Business Segments	(18) Business Segments The Company offers general contracting, pre-construction planning and comprehensive project management services, including planning and scheduling of manpower, equipment, materials and subcontractors required for the timely completion of a project in accordance with the terms and specifications contained in a construction contract. The Company also offers self-performed construction services: site work, concrete forming and placement, steel erection, electrical, mechanical, plumbing, and HVAC (heating, ventilation and air conditioning). As described below, the Company’s business is conducted through three segments: Civil, Building and Specialty Contractors. These segments are determined based on how the Company’s Chairman and Chief Executive Officer (chief operating decision maker) aggregates business units when evaluating performance and allocating resources. The Civil segment specializes in public works construction and the replacement and reconstruction of infrastructure. The contracting services provided by the Civil segment include construction and rehabilitation of highways, bridges, tunnels, mass-transit systems, and water management and wastewater treatment facilities. The Building segment has significant experience providing services for private and public works customers in a number of specialized building markets, including: high-rise residential, hospitality and gaming, transportation, health care, commercial and government offices, sports and entertainment, education, correctional facilities, biotech, pharmaceutical, industrial and technology. The Specialty Contractors segment specializes in electrical, mechanical, plumbing, HVAC, fire protection systems and pneumatically placed concrete for a full range of civil and building construction projects in the industrial, commercial, hospitality and gaming, and mass-transit end markets. This segment provides the Company with unique strengths and capabilities that allow the Company to position itself as a full-service contractor with greater control over scheduled work, project delivery, and cost and risk management. To the extent that a contract is co-managed and co-executed among segments, the Company allocates the share of revenues and costs of the contract to each segment to reflect the shared responsibilities in the management and execution of the project.

Contract Assets And Liabilities [Abstract]
Schedule Of Contract Assets And Liabilities	As of June 30, As of December 31, (in thousands) 2020 2019 Retainage receivable $ 581,495 $ 562,375 Costs and estimated earnings in excess of billings: Claims 729,170 705,993 Unapproved change orders 348,043 362,264 Other unbilled costs and profits 71,890 55,287 Total costs and estimated earnings in excess of billings 1,149,103 1,123,544 Capitalized contract costs 88,185 80,294 Total contract assets $ 1,818,783 $ 1,766,213 Retainage receivable represents amounts invoiced to customers where payments have been partially withheld pending the completion of certain milestones, satisfaction of other contractual conditions or the completion of the project. Retainage agreements vary from project to project, and balances could be outstanding for several months or years depending on a number of circumstances such as contract-specific terms, project performance and other variables that may arise as the Company makes progress toward completion. Costs and estimated earnings in excess of billings represent the excess of contract costs and profits (or contract revenue) over the amount of contract billings to date and are classified as a current asset. Costs and estimated earnings in excess of billings result when either: (1) the appropriate contract revenue amount has been recognized over time in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”) , but a portion of the revenue recorded cannot be billed currently due to the billing terms defined in the contract, or (2) costs are incurred related to certain claims and unapproved change orders. Claims occur when there is a dispute regarding both a change in the scope of work and the price associated with that change. Unapproved change orders occur when a change in the scope of work results in additional work being performed before the parties have agreed on the corresponding change in the contract price. The Company routinely estimates recovery related to claims and unapproved change orders as a form of variable consideration at the most likely amount it expects to receive and to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Claims and unapproved change orders are billable upon the agreement and resolution between the contractual parties and after the execution of contractual amendments. Increases in claims and unapproved change orders typically result from costs being incurred against existing or new positions; decreases normally result from resolutions and subsequent billings. As discussed in Note 11, the resolution of these claims and unapproved change orders may require litigation or other forms of dispute resolution proceedings. Other unbilled costs and profits are billable in accordance with the billing terms of each of the existing contractual arrangements and, as such, the timing of contract billing cycles can cause fluctuations in the balance of unbilled costs and profits. Ultimate resolution of other unbilled costs and profits typically involves incremental progress toward contractual requirements or milestones. Capitalized contract costs primarily represent costs to fulfill a contract that (1) directly relate to an existing or anticipated contract, (2) generate or enhance resources that will be used in satisfying performance obligations in the future and (3) are expected to be recovered through the contract, and are included in other current assets. Capitalized contract costs are generally expensed to the associated contract over the period of anticipated use on the project. During the three and six months ended June 30, 2020, $ 12.5 million and $ 22.8 million, respectively, of previously capitalized contract costs were amortized and recognized as expense on the related contracts. During the three and six months ended June 30, 2019, $ 8.6 million and $ 14.3 million, respectively, of previously capitalized contract costs were amortized and recognized as expense on the related contracts. Contract liabilities include amounts owed under retainage provisions and billings in excess of costs and estimated earnings. The amount as reported on the Condensed Consolidated Balance Sheets consisted of the following: As of June 30, As of December 31, (in thousands) 2020 2019 Retainage payable $ 278,045 $ 252,181 Billings in excess of costs and estimated earnings 962,446 844,389 Total contract liabilities $ 1,240,491 $ 1,096,570
