Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements were prepared in conformity with generally accepted accounting principles in the United States (“GAAP”). Pursuant to GAAP, certain information and footnote disclosures normally included in the annual consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the annual consolidated financial statements included in the Company’s 2025 Annual Report on Form 10-K (“2025 Annual Report”). The information includes all adjustments that are, in the opinion of management, necessary for a fair presentation of the unaudited condensed consolidated financial statements and are of a normal recurring nature. The results of operations for the three months ended March 31, 2026, are not necessarily indicative of the results to be expected for the year ending December 31, 2026 or any other future period. All revenues and costs, as well as assets and liabilities, directly associated with the business activities of the Company are included in the unaudited condensed consolidated financial statements. General corporate expenses are included within Selling, general and administrative expenses and Other income, net on the unaudited condensed consolidated statements of income.
Principles of Consolidation	Principles of Consolidation The unaudited condensed consolidated financial statements were prepared in accordance with GAAP and include the accounts of the Company and its wholly owned subsidiaries, as well as entities that the Company controls through its ownership of a majority voting interest or pursuant to control of a variable interest entity (“VIE”), which is discussed in more detail below. All significant intercompany accounts and transactions between the businesses comprising the Company have been eliminated in the accompanying unaudited condensed consolidated financial statements.
Use of Estimates	Use of Estimates The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the unaudited condensed consolidated financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Estimates are used for items such as long-lived assets and goodwill; fair values of acquired assets and liabilities under the acquisition method of accounting; property depreciable lives; tax provisions; revenue recognized using the cost-to-cost measure of progress for contracts; costs on construction contracts; unbilled revenues; expected credit losses; loss contingencies; actuarially determined benefit costs; lease classification; present value of right-of-use assets and lease liabilities; and the valuation of stock-based compensation. As additional information becomes available, or actual amounts are determinable, the recorded estimates are revised. Consequently, operating results can be affected by revisions to prior accounting estimates.
Consolidation of Variable Interest Entities	Consolidation of Variable Interest Entities The Company holds a minority economic interest in a captive insurance company, which has been determined to be a VIE due to its variable ownership interest in the captive insurance company. The captive insurance is structured with protected cell captives for each insured party (“Captive Cells”) in which participants’ assets and liabilities are held separately from each other and is not exposed to the insurance and investment risks that the Captive Cells are designed to create and distribute on behalf of the insured parties. The Company is the primary beneficiary of its individual Captive Cell and has the power to direct the activities that most significantly impact economic performance of its Captive Cell, as well as the obligation to absorb losses of, and receive benefits from the activities of its Captive Cell. Accordingly, the Company has prepared these unaudited condensed consolidated financial statements in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, Consolidation. ASC 810 requires that if an entity is the primary beneficiary of a VIE, the assets, liabilities, and results of operations of the VIE should be included in the unaudited condensed consolidated financial statements of such entity. As such, the unaudited condensed consolidated financial statements include the consolidation of the Company’s Captive Cell. Cash deposits held by the Captive Cell are considered restricted cash as they are to remain in the Captive Cell.
Joint Venture	Joint Ventures The Company accounts for unconsolidated joint ventures using either the equity method or proportionate consolidation. Proportionate consolidation is used for joint ventures that include unincorporated legal entities when we hold an undivided interest in each asset and are proportionately liable for our share of liabilities and the activities of the joint ventures that are construction related. For those joint ventures accounted for under proportionate consolidation, only the Company’s pro rata share of assets, liabilities, revenues and expenses are included in the Company’s unaudited condensed consolidated financial statements. There was no activity during the three months ended March 31, 2026 and 2025, related to joint ventures accounted for using proportionate consolidation. For those joint ventures accounted for under the equity method, the Company’s investment balances for the joint ventures are included in Investments in the unaudited condensed consolidated balance sheets, and the Company’s pro rata share of net income is included in Income from equity method investments in the unaudited condensed consolidated statements of income.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash As of March 31, 2026 and December 31, 2025, the Company’s cash was held in highly liquid bank accounts, including checking accounts and/or money market deposit accounts. In addition, the Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Restricted cash represents deposits held by the Company’s Captive Cell that are to be used solely for the Captive Cell’s purposes.
New Accounting Standards	New Accounting Standards Changes to GAAP are typically established by the FASB in the form of Accounting Standards Update (“ASU”) to the FASB ASC. The Company considers the applicability and impact of all ASUs. Recently Adopted Accounting Standards Updates In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which provided guidance to address stakeholders feedback on the challenges of applying Topic 326 to current accounts receivable and current contract assets, specifically related to the costs and complexities of developing reasonable and supportable forecasts to support the estimation of expected credit losses. As a result, this update provides a practical expedient for all entities that allows an entity to assume that current conditions as of the balance sheet date do not change for the remaining life of the asset when developing such forecasts. The standard is effective for fiscal year December 31, 2026, and interim periods beginning January 1, 2026. The Company adopted the standard in the first quarter of 2026 and it did not have a material impact on the unaudited condensed consolidated financial statements. New Accounting Standards Updates Not Yet Adopted In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which provided guidance to address investors’ requests for more detailed information about the types of expenses including purchases of inventory, employee compensation, depreciation, amortization, and depletion in commonly presented expense captions, such as cost of sales, selling, general and administrative expenses, and research and development costs. The standard will be effective for fiscal year December 31, 2027, and interim periods beginning January 1, 2028. Early adoption is permitted. The Company is currently evaluating the impact the guidance will have on its disclosures for the year ending December 31, 2027, and future interim periods beginning in 2028. In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which provided guidance to address stakeholders feedback for modernizing the accounting for internal-use software costs due to the different methods of software development. This update amended the accounting and disclosure of internal-use software costs and provided entities updated recognition requirements for capitalizing internal-use software development costs, as well as website development costs. The standard will be effective for fiscal year December 31, 2028, and interim periods beginning January 1, 2028. Early adoption is permitted as of the beginning of an annual reporting period. The Company is currently evaluating the impact the guidance will have on its consolidated financial statements as well as whether the Company will early-adopt the standard. In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements, which provided clarity on interim reporting disclosure requirements and which disclosures should be provided in interim reporting periods. The standard will be effective for fiscal year December 31, 2028, and interim periods beginning January 1, 2028. Early adoption is permitted as of the beginning of an annual reporting period. The Company is currently evaluating the disclosure impacts the guidance will have on its interim financial statements as well as whether the Company will early-adopt the standard.
Revenue from Contracts with Customers	Revenue from Contracts with Customers Under ASC 606 - Revenue from Contracts with Customers (“ASC 606”), revenue is recognized when a performance obligation is satisfied by transferring control over a product or service to a customer. Revenue is measured based on consideration specified in a contract with a customer and excludes any sales incentives and amounts collected on behalf of third parties. The Company is considered an agent for certain taxes collected from customers. As such, the Company presents revenues net of these taxes at the time of sale to be remitted to governmental authorities, including sales and use taxes. As part of the adoption of ASC 606, the Company elected the practical expedient to recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the Company otherwise would have recognized is 12 months or less. Contract Estimates and Changes in Estimates Changes in cost estimates on certain contracts can arise from, but not limited to, changes in productivity and performance expectations, availability of skilled labor in geographic locations of such projects, costs of labor and/or materials, changes in subcontractor productivity and performance, and extended overhead due to weather or other delays. These changes in estimates may result in the issuance of change orders, which can be approved or unapproved by the customer, or the assertion of contract claims. The Company recognizes amounts associated with change orders and claims as revenue if it is probable that the contract price will be adjusted and the amount of any such adjustment can be reasonably estimated. Change orders and claims are negotiated in the normal course of business and represent management's estimates of additional contract revenues that have been earned and are probable of collection. hanges in estimates may result from contract modifications, which affect the estimated progress of the related performance obligations. As a result, the Company recognizes additional revenues on a cumulative catch-up basis in the current period from performance obligations that were satisfied or partially satisfied in prior periods or the reversal of previously recognized revenues if the current estimated progress is less than the previous estimate. In some instances, contract modifications may occur after completion of work under the contract. Changes in estimates can also result in contract losses, which are recognized in full when they are determined to be probable and can be reasonably estimated. Since these changes in estimates could significantly affect our profitability, the Company reviews and updates contract-related estimates regularly and recognizes adjustments in estimated gross profit on contracts under the cumulative catch-up method. Under this method, the cumulative impact to gross profit is recognized in the period that the adjustment is identified. As such, future operating revenues and gross profit of contract performance are recognized using the adjusted estimates.
Fair Value Measurements	The estimated fair value of the Company’s Level 2 COLI contracts was based on contractual cash surrender values that were determined primarily by investments in managed separate accounts of the insurer. These amounts approximated fair value. The managed separate accounts were valued based on other observable inputs or corroborated market data. Though the Company believes the methods used to estimate fair value are consistent with those used by other market participants, the use of other methods or assumptions could result in a different estimate of fair value. The estimated fair values of the Company’s Cash, cash equivalents and restricted cash, Receivables, Accounts payable and Other accrued liabilities approximated their carrying value due to the short-term maturities of these instruments. The Company has a captive insurance arrangement in which a Captive Cell within a captive insurance company holds cash, classified as restricted cash, and certain other accrued liabilities and other noncurrent liabilities in order to manage and administer insurance claims on behalf of the Company. The fair values of the assets and liabilities held by the Captive Cell approximated their fair values as of March 31, 2026 and December 31, 2025, respectively.
Earnings Per Share	Earnings Per Share Basic EPS is computed by dividing net income by the weighted average number of shares of common stock outstanding during the applicable period. The Company calculates diluted EPS using the treasury stock method. Diluted EPS is computed by dividing net income by the total of the weighted average number of shares of common stock outstanding during the applicable period, plus the effect of any potentially dilutive securities, except in cases where the effect of such securities would be anti-dilutive.
