Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The consolidated financial statements of the Company are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for reporting of interim financial information. Pursuant to such rules and regulations, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. In the opinion of management, the accompanying unaudited interim consolidated financial statements of the Company contain all adjustments necessary to present fairly the financial position and results of operations of the Company as of the dates and for the periods presented. Accordingly, these statements should be read in conjunction with the consolidated financial statements and notes contained in the Company’s Annual Report on Form 10-K for the year ended December 30, 2023 (the “2023 Form 10-K”). The results of operations and cash flows for the interim periods presented are not necessarily indicative of the results to be expected for any future interim period or for the full 2024 fiscal year. Performance Obligations To determine the proper revenue recognition method, the Company evaluates whether two or more contracts should be combined and accounted for as one single contract and whether the combined or single contract should be accounted for as more than one performance obligation. The majority of the Company's contracts have a single performance obligation as the promise to transfer the individual goods or services that is not separately identifiable from other promises in the contracts and therefore, is not distinct. The Company’s performance obligations are satisfied as work progresses or at a point in time. Revenue on the Company's cost-reimbursable contracts is recognized over time using direct costs incurred or direct costs incurred to date as compared to the estimated total direct costs for performance obligations because it depicts the transfer of control to the customer. Contract costs include labor, sub-consultant services, and other direct costs. Gross revenue from services transferred to customers at a point in time is recognized when the customer obtains control of the asset, which is generally upon delivery and acceptance by the customer of the reports and/or analysis performed. As of September 28, 2024, the Company had $1,000,339 of remaining performance obligations, of which $771,433 is expected to be recognized over the next 12 months and the majority of the balance over the next 24 months. Contracts for which work authorizations have been received are included in performance obligations. Performance obligations include only those amounts that have been funded and authorized and does not reflect the full amounts the Company may receive over the term of such contracts. In the case of non-government contracts and project awards, performance obligations include future revenue at contract or customary rates, excluding contract renewals or extensions that are at the discretion of the client. For contracts with a not-to-exceed maximum amount, the Company includes revenue from such contracts in performance obligations to the extent of the remaining estimated amount. Contract Balances The timing of revenue recognition, billings, and cash collections results in billed receivables, unbilled receivables (contract assets), and billings in excess of costs and estimated earnings on uncompleted contracts (contract liabilities) on the Consolidated Balance Sheet. The liability “Billings in excess of costs and estimated earnings on uncompleted contracts” represents billings in excess of revenues recognized on these contracts as of the reporting date. This liability is generally classified as current. During the three and nine months ended September 28, 2024 the Company performed services and recognized $6,672 and $40,883, respectively, of revenue related to its contract liabilities that existed as of December 30, 2023. Goodwill and Intangible Assets Goodwill is the excess of consideration paid for an acquired entity over the amounts assigned to assets acquired, including other identifiable intangible assets and liabilities assumed in a business combination. To determine the amount of goodwill resulting from a business combination, the Company performs an assessment to determine the acquisition date fair value of the acquired company’s tangible and identifiable intangible assets and liabilities. Goodwill is required to be evaluated for impairment on an annual basis or whenever events or changes in circumstances indicate the asset may be impaired. An entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. These qualitative factors include macroeconomic and industry conditions, cost factors, overall financial performance, and other relevant entity-specific events. If the entity determines that this threshold is met, then the Company applies a one-step quantitative test and record the amount of goodwill impairment as the excess of a reporting unit's carrying amount over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The Company determines fair value through multiple valuation techniques, and weights the results accordingly. Subjective and complex judgments are required in assessing whether an event of impairment of goodwill has occurred, including assumptions and estimates used to determine the fair value of its reporting units. The Company has elected to perform its annual goodwill impairment review as of August 1 of each year. The Company conducts its annual impairment tests on the goodwill using the quantitative method of evaluating goodwill. As of August 1, 2024, the Company conducted its annual impairment tests using the quantitative method of evaluating goodwill. Based on the quantitative analyses the Company determined the fair value of each of the reporting units exceeded its carrying value. Therefore, the goodwill was not impaired and the Company did not recognize an impairment charge relating to goodwill as of August 1, 2024. Furthermore, there were no indicators, events, or changes in circumstances that would indicate goodwill was impaired during the period from August 2, 2024 through September 28, 2024. Identifiable intangible assets primarily include customer backlog, customer relationships, trade names, non-compete agreements, and developed technology. Amortizable intangible assets are amortized on either a straight-line or sum-of-the-years' digits basis over their estimated useful lives and reviewed for impairment whenever events or changes in circumstances indicate that the assets may be impaired. If an indicator of impairment exists, the Company compares the estimated future cash flows of the asset, on an undiscounted basis, to the carrying value of the asset. If the undiscounted cash flows exceed the carrying value, no impairment is indicated. If the undiscounted cash flows do not exceed the carrying value, then impairment, if any, is measured as the difference between fair value and carrying value, with fair value typically based on a discounted cash flow model. There were no indicators, events, or changes in circumstances that would indicate intangible assets were impaired during the nine months ended September 28, 2024. See Note 8, Goodwill and Intangible Assets , for further information on goodwill and identified intangibles. There have been no material changes in the Company's significant accounting policies described in the audited financial statements included in the Company's Annual Report on Form 10-K for the year ended December 30, 2023. Correction of Previously Issued Financial Statements In mid-October 2024, in the course of completing the preparation of these unaudited consolidated financial statements, the Company identified out of period misstatements related to the estimated time to complete ("ETC") on acquired percentage-of-completion ("POC") projects related to the February 2023 acquisition of Continental Mapping Acquisition Corp. and its subsidiaries, including Axim Geospatial, LLC (collectively "Axim"). Incorrect ETCs utilized as part of purchase accounting created a misstatement of the Company's unbilled receivables, goodwill, intangible assets (customer relationships, backlog, and non-competes), and billings in excess of costs and estimated earnings on uncompleted contracts. Incorrect ETCs further created a misstatement of accounts payable, accrued liabilities, retained earnings, gross revenues, sub-consultant services, gross profit, amortization expense, income before income tax benefit (expense), income tax benefit (expense), net income, and earnings per share in the consolidated financial statements included in the Form 10-K for the period ending December 30, 2023, the interim periods in the Form 10-Qs filed within fiscal year 2023, and the most recently filed Form 10-Qs for the quarters ended March 30, 2024, and June 29, 2024. The Company assessed the materiality of the errors, including the presentation on prior period consolidated financial statements, on a qualitative and quantitative basis in accordance with SEC Staff Accounting Bulletin Topics 1.M and 1.N (formerly No. 99, Materiality) , codified in Accounting Standards Codification Topic 250, Accounting Changes and Error Corrections . Based on this assessment, the Company concluded that these errors and the related impacts did not result in a material misstatement of our previously issued consolidated financial statements as of and for the period ending December 30, 2023, the interim periods on the Form 10-Qs filed within fiscal year 2023, and the most recently filed Form 10-Qs for the quarters ended March 30, 2024, and June 29, 2024. However, correcting the cumulative effect of these errors in the three months ended September 28, 2024 would have a significant effect on the results of operations for the periods. Accordingly, the Company revised its historical financial statements prospectively to correct these errors and to facilitate comparisons of the Company's current results to prior periods. A summary of the corrections to the impacted financial statement line items in the Company's previously issued Consolidated Balance Sheet, Consolidated Statement of Net Income and Comprehensive Income, and Consolidated Statement of Cash Flows as of and for the year ended December 30, 2023 included in the previously filed Annual Report on Form 10-K and Consolidated Balance Sheet, Consolidated

Earnings Per Share [Abstract]
Earnings per Share	Earnings per Share Basic earnings per share is calculated by dividing net income by the weighted average number of common shares outstanding during the period, excluding unvested restricted shares. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the Company. The effect of potentially dilutive securities is not considered during periods of loss or if the effect is anti-dilutive. On September 25, 2024, the Company announced a 4-for-1 forward split (the "Stock Split") of its common stock, par value $0.01 per share (the "Common Stock"), to be effected through an amendment to the Company's Amended and Restated Certificate of Incorporation (the "Amendment"). The Amendment also effected a proportionate increase in the number of shares of authorized Common Stock and became effective at 4:30 p.m. Eastern Time on October 9, 2024. As a result of the Stock Split, each holder of record of Common Stock as of the close of business on October 9, 2024 received three additional shares of Common Stock after the close of trading on October 10, 2024. Trading in the Common Stock commenced on a split-adjusted basis on October 11, 2024. The weighted average number of shares outstanding in calculating basic earnings per share for the nine months ended September 28, 2024 and September 30, 2023 exclude 3,001,872 and 2,750,864 non-vested restricted shares, respectively. During the three and nine months ended September 28, 2024 there were 24,266 and 23,644 weighted average securities, respectively, which are not included in the calculation of diluted weighted average shares outstanding because their impact is anti-dilutive or their performance conditions have not been met. During the three and nine months ended September 30, 2023, there were 89,460 and 127,544 weighted average securities, respectively, which are not included in the calculation of diluted weighted average shares outstanding because their impact is anti-dilutive or their performance conditions have not been met. The following table represents a reconciliation of the net income and weighted average shares outstanding for the calculation of basic and diluted earnings per share: Three Months Ended Nine Months Ended September 28, 2024 September 30, 2023 September 28, 2024 September 30, 2023 Numerator: Net income – basic and diluted $ 17,078 $ 13,056 $ 22,549 $ 33,578 Denominator: Basic weighted average shares outstanding 61,982,888 60,840,402 61,500,930 60,143,591 Effect of dilutive non-vested restricted shares and units 1,010,679 1,050,836 1,183,866 1,550,626 Effect of issuable shares related to acquisitions 49,395 100,110 84,779 100,550 Diluted weighted average shares outstanding 63,042,962 61,991,348 62,769,575 61,794,767

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Business Acquisitions	Business Acquisitions 2024 Acquisitions The Company has completed six acquisitions during 2024. The aggregate purchase price for the six acquisitions was $65,159, including $56,427 in cash, $3,534 of the Company's common stock, and potential earn-outs of up to $14,100 payable in cash, which have been recorded at an estimated fair value of $5,198. The cash portions of the purchase prices and other related costs associated with the transactions were partially financed through the Company's amended and restated credit agreement (the "Second A&R Credit Agreement" or "Senior Credit Facility") with Bank of America, N.A. and other lenders party thereto. See Note 10, Notes Payable and Other Obligations , for further detail on the Second A&R Credit Agreement. An option-based model and a probability-weighted approach were used to determine the fair value of the earn-outs, which are generally accepted valuation techniques that embody all significant assumption types. In order to determine the fair values of tangible and intangible assets acquired and liabilities assumed, the Company engaged an independent third-party valuation specialist to assist in the determination of fair values. The final determination of the fair values of assets and liabilities will be completed within the one-year measurement period as required by ASC 805. The 2024 acquisitions will necessitate the use of this measurement period to adequately analyze and assess the factors used in establishing the asset and liability fair values as of the relevant acquisition date, including intangible assets, accounts receivable, prepaid expenses, deferred tax liabilities, and other certain liabilities. 2023 Acquisitions On April 6, 2023, the Company acquired all of the outstanding equity interests in the Visual Information Solutions commercial geospatial technology and software business ("VIS") from L3Harris. VIS is a provider of subscription-based software solutions for the analysis and management of software applications and Analytics as a Service (AaaS) solutions. The Company acquired VIS for a cash purchase price of $75,371. The purchase price and other related costs associated with the transaction were financed through the Company's Second A&R Credit Agreement. In order to determine the fair values of tangible and intangible assets acquired and liabilities assumed, the Company engaged an independent third-party valuation specialist to assist in the determination of fair values. The final determination of the fair value of assets and liabilities was completed within the one-year measurement period as required by ASC 805. On February 22, 2023, the Company acquired all of the outstanding equity interests in Continental Mapping Acquisition Corp. and its subsidiaries, including Axim Geospatial, LLC (collectively "Axim"), a provider of comprehensive geospatial services and solutions addressing critical mission requirements for customers across the defense and intelligence and state and local government sectors. The aggregate purchase price of the acquisition was $139,569, including $119,736 in cash, a $6,333 promissory note, and $13,500 of the Company's common stock. The cash portion of the purchase price and other related costs associated with the transaction were financed through the Company's Second A&R Credit Agreement. In order to determine the fair values of tangible and intangible assets acquired and liabilities assumed, the Company engaged an independent third-party valuation specialist to assist in the determination of fair values. The final determination of the fair value of assets and liabilities was completed within the one-year measurement period as required by ASC 805. The Company completed five other acquisitions during 2023. The aggregate purchase price for the five acquisitions was $9,477, including $8,000 in cash, $867 of the Company's common stock, and a potential earn-out of up to $640 payable in cash, which has been recorded at an estimated fair value of $610. A probability-weighted approach was used to determine the fair value of the earn-out, which is a generally accepted valuation technique that embodies all significant assumption types. The final determination of the fair value of assets and liabilities will be completed within the one-year measurement period as required by ASC 805. The 2023 acquisitions will necessitate the use of this measurement period to adequately analyze and assess the factors used in establishing the asset and liability fair values as of the relevant acquisition date, including intangible assets, accounts receivable, and deferred tax liabilities. The following table summarizes the fair values of the assets acquired and liabilities assumed as of the acquisition date for the acquisitions closed during the nine months ended September 28, 2024 and the fiscal year ended December 30, 2023: 2024 2023 Total VIS Axim Other Total Cash $ 2,080 $ 7,027 $ 5,419 $ 1,316 $ 13,762 Billed and unbilled receivables, net 6,678 5,042 12,080 1,609 18,731 Right-of-use assets 2,583 2,162 1,643 552 4,357 Property and equipment 1,762 118 2,870 38 3,026 Prepaid expenses 1,070 1,503 1,180 17 2,700 Other assets 46 — 156 2 158 Intangible assets: Customer relationships 29,390 35,626 36,439 2,526 74,591 Trade name 944 3,025 2,266 210 5,501 Customer backlog 4,455 894 2,155 943 3,992 Developed technology — 4,024 2,185 — 6,209 Non-compete 2,753 26 414 254 694 Total Assets $ 51,761 $ 59,447 $ 66,807 $ 7,467 $ 133,721 Liabilities (5,995) (16,689) (26,889) (2,297) (45,875) Deferred tax liabilities (131) (8,728) (3,624) (496) (12,848) Net assets acquired $ 45,635 $ 34,030 $ 36,294 $ 4,674 $ 74,998 Consideration paid (Cash, Notes and/or stock) $ 59,961 $ 75,371 $ 139,569 $ 8,867 $ 223,807 Contingent earn-out liability (Cash and stock) 5,198 — — 610 610 Total Consideration $ 65,159 $ 75,371 $ 139,569 $ 9,477 $ 224,417 Excess consideration over the amounts assigned to the net assets acquired (Goodwill) $ 19,524 $ 41,341 $ 103,275 $ 4,803 $ 149,419 Goodwill was recorded based on the amount by which the purchase price exceeded the fair value of the net assets acquired and the amount is attributable to the reputation of the business acquired, the workforce in place and the synergies to be achieved from these acquisitions.

Senior Credit Facility On August 13, 2021 (the "Closing Date"), the Company amended and restated its Credit Agreement (the "Second A&R Credit Agreement" or "Senior Credit Facility"), originally dated December 7, 2016 and as amended to the Closing Date, with Bank of America, N.A. ("Bank of America"), as administrative agent, swingline lender and letter of credit issuer, the other lenders party thereto, and certain of the Company's subsidiaries as guarantors. Pursuant to the Second A&R Credit Agreement, the previously drawn term commitments of $150,000 and revolving commitments totaling $215,000 in the aggregate were converted into revolving commitments totaling $400,000 in the aggregate. These revolving commitments are available through August 13, 2026 (the "Maturity Date") and an aggregate amount of approximately $138,750 was drawn under the Second A&R Credit Amendment on the Closing Date to repay previously existing borrowings under the term and revolving facilities prior to such amendment and restatement. Borrowings under the Second A&R Credit Agreement are secured by a first priority lien on substantially all of the assets of the Company. The Second A&R Credit Agreement also includes an accordion feature permitting the Company to request an increase in the revolving facility under the Second A&R Credit Agreement by an additional amount of up to $200,000 in the aggregate. As of September 28, 2024 and December 30, 2023, the outstanding balance on the Second A&R Credit Agreement was $241,750 and $195,750, respectively. Borrowings under the Second A&R Credit Agreement bear interest at variable rates which are, at the Company's option, tied to a Eurocurrency rate equal to either Term SOFR (Secured Overnight Financing Rate) or Daily Simple SOFR, plus in each case an applicable margin or a base rate denominated in U.S. dollars. Interest rates remain subject to change based on the Company's consolidated leverage ratio. As of September 28, 2024, the Company's weighted average interest rate was 6.7%. The Second A&R Credit Agreement contains financial covenants that require NV5 Global to maintain a consolidated net leverage ratio (the ratio of the Company's pro forma consolidated net funded indebtedness to the Company's pro forma consolidated EBITDA for the most recently completed measurement period) of no greater than 4.00 to 1.00. These financial covenants also require the Company to maintain a consolidated fixed charge coverage ratio of no less than 1.10 to 1.00 as of the end of any measurement period. As of September 28, 2024, the Company was in compliance with the financial covenants. The Second A&R Credit Agreement contains covenants that may have the effect of limiting the Company's ability to, among other things, merge with or acquire other entities, enter into a transaction resulting in a Change in Control, create certain new liens, incur certain additional indebtedness, engage in certain transactions with affiliates, or engage in new lines of business or sell a substantial part of their assets. The Second A&R Credit Agreement also contains customary events of default, including (but not limited to) a default in the payment of principal or, following an applicable grace period, interest, breaches of the Company's covenants or warranties under the Second A&R Credit Agreement, payment default or acceleration of certain indebtedness, certain events of bankruptcy, insolvency or liquidation, certain judgments or uninsured losses, changes in control and certain liabilities related to ERISA based plans. The Second A&R Credit Agreement limits the payment of cash dividends (together with certain other payments that would constitute a "Restricted Payment" within the meaning of the Second A&R Credit Agreement and generally including dividends, stock repurchases and certain other payments in respect to warrants, options, and other rights to acquire equity securities), unless the Consolidated Leverage Ratio would be less than 3.25 to 1.00 and available liquidity (defined as unrestricted, domestically held cash plus revolver availability) would be at least $30,000, in each case after giving effect to such payment. Total debt issuance costs incurred and capitalized in connection with the issuance of the Second A&R Credit Agreement were $3,702. Total amortization of debt issuance costs was $185 and $556 during the three and nine months ended September 28, 2024, respectively, and $208 and $573 during the three and nine months ended September 30, 2023, respectively. Other Obligations The Company has aggregate obligations related to acquisitions of $11,013 and $16,491 as of September 28, 2024 and December 30, 2023, respectively.

The Company carries professional liability insurance, subject to certain deductibles and policy limits, against such claims. However, in some actions, parties are seeking damages that exceed our insurance coverage or for which we are not insured. While management does not believe that the resolution of these claims will have a material adverse effect, individually or in aggregate, on its financial position, results of operations or cash flows, management acknowledges the uncertainty surrounding the ultimate resolution of these matters.

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation In June 2023, the Company's stockholders approved the NV5 Global, Inc. 2023 Equity Incentive Plan (the "2023 Equity Plan"). The 2023 Equity Plan provides directors, executive officers, and other employees of the Company with additional incentives by allowing them to acquire ownership interest in the business and, as a result, encouraging them to contribute to the Company’s success. The Company may provide these incentives through the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares and units, and other cash-based or stock-based awards. As of September 28, 2024, 7,213,696 shares of common stock are authorized, reserved, and registered for issuance under the 2023 Equity Plan. The restricted shares of common stock granted generally provide for service-based cliff vesting after two The following summarizes the activity of restricted stock awards during the nine months ended September 28, 2024: Number of Unvested Restricted Shares of Common Stock and Restricted Stock Units Weighted Average December 30, 2023 2,707,040 $ 26.16 Granted 1,398,808 $ 23.78 Vested (878,528) $ 22.90 Forfeited (65,232) $ 24.93 September 28, 2024 3,162,088 $ 26.06 Stock-based compensation expense relating to restricted stock awards during the three and nine months ended September 28, 2024 was $5,955 and $19,943, respectively, and $5,777 and $16,504 during the three and nine months ended September 30, 2023, respectively. Stock-based compensation expense during the three and nine months ended September 28, 2024 includes $492 and $2,302, respectively, of expense related to the Company's liability-classified awards. Stock-based compensation expense during the three and nine months ended September 30, 2023 includes $318 and $1,473, respectively, of expense related to the Company's liability-classified awards. The total estimated amount of the liability-classified awards for fiscal 2024 is approximately $8,625. Approximately $44,720 of deferred compensation, which is expected to be recognized over the remaining weighted average vesting period of 1.79 years, is unrecognized at September 28, 2024. The total fair value of restricted shares vested during the nine months ended September 28, 2024 and September 30, 2023 was $19,887 and $29,235, respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes As of September 28, 2024 and December 30, 2023, the Company had net deferred income tax assets of $20,296 and $6,388, respectively. Net deferred income tax assets are primarily due to the capitalization of research and development costs under Section 174 of the Internal Revenue Code and the amortization of intangible assets. The Company's effective income tax rate was (7.0%) and (11.1%) during the three and nine months ended September 28, 2024, respectively, and (20.1)% and 1.1% during the three and nine months ended September 30, 2023, respectively. The difference between the effective income tax rate and the combined statutory federal and state income tax rate was primarily due to an increase in federal tax credits and a decrease in the recognition of excess tax benefits from stock-based payments during the nine months ended September 28, 2024 as compared to the the nine months ended September 30, 2023. The Company evaluates tax positions for recognition using a more-likely-than-not recognition threshold, and those tax positions eligible for recognition are measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon the effective settlement with a taxing authority that has full knowledge of all relevant information. Fiscal years 2012 through 2014 are considered open tax years in the State of California. Fiscal years 2020 through 2023 are considered open tax years in the U.S. federal jurisdiction, state jurisdictions, including the State of California, and foreign jurisdictions. It is not expected that there will be a significant change in the unrecognized tax benefits within the next 12 months.

Segment Reporting [Abstract]
Reportable Segments	Reportable Segments The Company reports segment information in accordance with ASC Topic No. 280 “ Segment Reporting” (“Topic No. 280”). The Company is organized into three operating and reportable segments: Infrastructure ("INF"), which includes the Company's engineering, civil program management, utility services, and construction quality assurance practices; Building, Technology & Sciences ("BTS"), which includes the Company's clean energy consulting, data center commissioning and consulting, buildings and program management, MEP & technology design practices, and environmental health sciences; and Geospatial Solutions ("GEO"), which includes the Company's geospatial solution practices. The Company's chief operating decision maker ("CODM") group is comprised of the Company's Executive Chairman and Co-Chief Executive Officers. The Company identified changes to the CODM group effective March 1, 2024 when Dickerson Wright transitioned from his role as Chief Executive Officer to Executive Chairman of the Company, and Alexander Hockman and Benjamin Heraud were appointed Co-Chief Executive Officers. There was no change in the Company's operating or reportable segments as a result of the change in CODM. The Company evaluates the performance of these reportable segments based on their respective operating income before the effect of amortization expense related to acquisitions and other unallocated corporate expenses. The following tables set forth summarized financial information concerning our reportable segments: Three Months Ended Nine Months Ended September 28, 2024 September 30, 2023 September 28, 2024 September 30, 2023 Gross revenues INF $ 100,891 $ 102,136 $ 291,987 $ 287,074 BTS 65,699 57,235 189,281 164,113 GEO 84,295 78,174 213,482 191,114 Total gross revenues $ 250,885 $ 237,545 $ 694,750 $ 642,301 Segment income before taxes INF $ 16,592 $ 15,902 $ 48,713 $ 49,628 BTS 10,944 10,226 31,426 26,757 GEO 22,998 14,783 45,932 34,317 Total Segment income before taxes 50,534 40,911 126,071 110,702 Corporate (1) (34,566) (30,040) (105,772) (76,742) Total income before taxes $ 15,968 $ 10,871 $ 20,299 $ 33,960 (1) Includes amortization of intangibles of $12,654 and $37,235 for the three and nine months ended September 28, 2024, respectively, and $10,731 and $29,869 during the three and nine months ended September 30, 2023, respectively. The Company disaggregates its gross revenues from contracts with customers by geographic location, customer-type and contract-type for each of our reportable segments.

Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The consolidated financial statements of the Company are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for reporting of interim financial information. Pursuant to such rules and regulations, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. In the opinion of management, the accompanying unaudited interim consolidated financial statements of the Company contain all adjustments necessary to present fairly the financial position and results of operations of the Company as of the dates and for the periods presented. Accordingly, these statements should be read in conjunction with the consolidated financial statements and notes contained in the Company’s Annual Report on Form 10-K for the year ended December 30, 2023 (the “2023 Form 10-K”). The results of operations and cash flows for the interim periods presented are not necessarily indicative of the results to be expected for any future interim period or for the full 2024 fiscal year.
Performance Obligations	Performance Obligations To determine the proper revenue recognition method, the Company evaluates whether two or more contracts should be combined and accounted for as one single contract and whether the combined or single contract should be accounted for as more than one performance obligation. The majority of the Company's contracts have a single performance obligation as the promise to transfer the individual goods or services that is not separately identifiable from other promises in the contracts and therefore, is not distinct. The Company’s performance obligations are satisfied as work progresses or at a point in time. Revenue on the Company's cost-reimbursable contracts is recognized over time using direct costs incurred or direct costs incurred to date as compared to the estimated total direct costs for performance obligations because it depicts the transfer of control to the customer. Contract costs include labor, sub-consultant services, and other direct costs. Gross revenue from services transferred to customers at a point in time is recognized when the customer obtains control of the asset, which is generally upon delivery and acceptance by the customer of the reports and/or analysis performed. As of September 28, 2024, the Company had $1,000,339 of remaining performance obligations, of which $771,433 is expected to be recognized over the next 12 months and the majority of the balance over the next 24 months. Contracts for which work authorizations have been received are included in performance obligations. Performance obligations include only those amounts that have been funded and authorized and does not reflect the full amounts the Company may receive over the term of such contracts. In the case of non-government contracts and project awards, performance obligations include future revenue at contract or customary rates, excluding contract renewals or extensions that are at the discretion of the client. For contracts with a not-to-exceed maximum amount, the Company includes revenue from such contracts in performance obligations to the extent of the remaining estimated amount. Contract Balances
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill is the excess of consideration paid for an acquired entity over the amounts assigned to assets acquired, including other identifiable intangible assets and liabilities assumed in a business combination. To determine the amount of goodwill resulting from a business combination, the Company performs an assessment to determine the acquisition date fair value of the acquired company’s tangible and identifiable intangible assets and liabilities. Goodwill is required to be evaluated for impairment on an annual basis or whenever events or changes in circumstances indicate the asset may be impaired. An entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. These qualitative factors include macroeconomic and industry conditions, cost factors, overall financial performance, and other relevant entity-specific events. If the entity determines that this threshold is met, then the Company applies a one-step quantitative test and record the amount of goodwill impairment as the excess of a reporting unit's carrying amount over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The Company determines fair value through multiple valuation techniques, and weights the results accordingly. Subjective and complex judgments are required in assessing whether an event of impairment of goodwill has occurred, including assumptions and estimates used to determine the fair value of its reporting units. The Company has elected to perform its annual goodwill impairment review as of August 1 of each year. The Company conducts its annual impairment tests on the goodwill using the quantitative method of evaluating goodwill. As of August 1, 2024, the Company conducted its annual impairment tests using the quantitative method of evaluating goodwill. Based on the quantitative analyses the Company determined the fair value of each of the reporting units exceeded its carrying value. Therefore, the goodwill was not impaired and the Company did not recognize an impairment charge relating to goodwill as of August 1, 2024. Furthermore, there were no indicators, events, or changes in circumstances that would indicate goodwill was impaired during the period from August 2, 2024 through September 28, 2024.
