Nature Of Business And Basis Of Presentation [Abstract]
Nature of Business and Basis of Presentation	Nature of Business and Basis of Presentation Nature of Business Bowman Consulting Group Ltd. (along with its consolidated subsidiaries, “Bowman” or “we” or the “Company”) incorporated in the Commonwealth of Virginia on June 5, 1995 and reincorporated in the State of Delaware on November 13, 2020. Bowman is a professional services firm delivering innovative solutions to the marketplace of customers who own, develop and maintain the built environment. Within that arena, we provide planning, design, engineering, geospatial, survey, construction management, environmental consulting and land procurement services to markets that encompass the buildings in which people live, work and learn in; as well as the systems that provide water, electricity and other vital services, and the roads, bridges, and transportation systems used to get from place to place. We provide services to customers through fixed-price and time-and-material based contracts containing multiple milestones and independently priced deliverables. Typically, contract awards are on a negotiated basis, ranging in value from a few thousand dollars to multiple millions of dollars and can have varying durations depending on the size, scope, and complexity of the project. The Company’s workforce typically provides the full scope of engineering and other contract services. However, with respect to certain specialty services or other compliance requirements within a particular contract, we may engage third-party sub-consultants. The Company’s headquarters is located in Reston, VA and the Company has over 70 offices throughout the United States and one office in Mexico. Common Stock Offering On February 11, 2022, the Company closed on an offering of common stock in which it issued and sold 900,000 shares at an offering price of $16.00 per share, resulting in net proceeds of $13.7 million after deducting underwriting discounts and commissions, but before expenses of the offering. In addition, Gary Bowman, our President, Chairman and Chief Executive Officer, sold 150,000 shares of common stock. On February 28, 2022, the underwriters exercised their option to purchase an additional 157,500 shares of the Company’s common stock at an offering price of $16.00 per share, resulting in additional gross proceeds of approximately $2.5 million. After giving effect to this exercise of the overallotment option, the total number of shares sold by the Company in this common stock offering increased to 1,057,500 shares with total gross proceeds of approximately $16.9 million. The exercise of the over-allotment option closed on March 2, 2022, at which time the Company received net proceeds of $2.4 million after underwriting discounts and commissions. Deferred offering costs consist primarily of accounting, legal and other fees related to the common stock offering. Prior to the offering, all deferred offering costs were capitalized within prepaid and other current assets in the consolidated balance sheet. No deferred offering costs were capitalized in the consolidated balance sheet as of March 31, 2023. Basis of Presentation The accompanying unaudited condensed consolidated financial statements and footnotes of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial information. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position, changes in shareholders’ equity and cash flows. The results of operations for the current period are not necessarily indicative of the results for the full year or the results for any future periods. The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related footnotes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 filed with the SEC on March 15, 2023. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies The following is a summary of the significant accounting policies and principles used in the preparation of the condensed consolidated financial statements: Emerging Growth Company Section 102(b)(1) of the Jumpstart Our Business Startups Act (“JOBS Act”) exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Securities Exchange Act of 1934 (the “Exchange Act”)) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company that is either not an emerging growth company or, an emerging growth company that has opted out of using the extended transition period, difficult or impossible because of the potential differences in accounting standards used. Revenue Recognition Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contract with Customers (“ASC Topic 606”) provides a single comprehensive revenue recognition framework and supersedes almost all revenue recognition guidance including industry-specific revenue guidance. The Company adopted this standard effective January 1, 2019, the first day of the Company's fiscal year. As discussed in Note 1, the Company provides a variety of engineering and related professional services to customers located throughout the United States. The Company enters into agreements with clients that create enforceable rights and obligations and for which it is probable that the Company will collect the consideration to which it will be entitled as services transfer to the customer. It is customary practice for the Company to have written agreements with its customers and revenue on oral or implied arrangements is generally not recognized. The Company recognizes revenue based on the consideration specified in the applicable agreement. Excluded from the transaction price are amounts collected on behalf of third parties for sales and similar taxes. Long-term contracts typically contain billing terms that provide for invoicing once a month and payment on a net 30-day basis. Exceptions to monthly billing terms are to ensure that the Company performs satisfactorily rather than representing a significant financing component. For example, fixed price contracts may provide for milestone billings based upon the attainment of specific project objectives to ensure the Company meets its contractual requirements rather than having billing monthly. Additionally, contracts may include retentions or holdbacks paid at the end of a project to ensure that Company meets the contract requirements. The Company does not assess whether a contract contains a significant financing component if the Company expects, at contract inception, that the period between payment by the customer and the transfer of promised services to the customer will be less than one year. As a professional services engineering firm, the Company generally recognizes revenue over time as control transfers to a customer based upon the extent of progress towards satisfaction of the performance obligation. For services delivered under fixed price contracts, the Company uses the ratio of actual costs incurred to total estimated costs since costs incurred (an input method) which represents a reasonable measure of progress towards the satisfaction of a performance in order to estimate the portion of revenue earned. This method faithfully depicts the transfer of value to the customer when the Company is satisfying a performance obligation that entails a number of interrelated tasks or activities for a combined output that requires the Company to coordinate the work of employees and sub-consultants. Contract costs typically include direct labor, subcontract and consultant costs, materials and indirect costs related to contract performance. Changes in estimated costs to complete these obligations result in adjustments to revenue on a cumulative catch-up basis, which causes the effect of revised estimates to be recognized in the current period. Changes in estimates can routinely occur over the contract term for a variety of reasons including, changes in scope, unanticipated costs, delays or favorable or unfavorable progress than original expectations. In situations where the estimated costs to perform exceeds the consideration to be received, the Company accrues the entire estimated loss during the period the loss becomes known. When a performance obligation is billed using a time-and-material type contract, the Company measures its progress to complete based upon the hours incurred for the period times contractually agreed upon billing rates plus any materials delivered or consumed in the project. When applicable, the Company will recognize revenue under these contracts as invoiced under the practical expedient. In certain situations, it is possible that two or more contracts should be combined and accounted for as a single contract, or a single contract should be accounted for as multiple performance obligations. This requires significant judgment and could impact the amount and timing of revenue recognition. Such determinations are made using management’s best estimate and knowledge of contracts and related performance obligations. The Company’s contracts may contain variable consideration in the form of unpriced or pending change orders or claims that either increase or decrease the contract price. Variable consideration is generally estimated using the expected value method but may from time to time be estimated using the most likely amount method depending on the circumstance. Estimated amounts are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. Estimates of variable consideration are based upon historical experience and known trends. The Company recognizes claims against vendors, sub-consultants, and others as a reduction in costs when the contract establishes enforceability, and the amounts of recovery are reasonably estimable and probable. Reduction in costs are recognized at the lesser of the amount management expects to recover or costs incurred. Contract related assets and liabilities are classified as current assets and current liabilities. Significant balance sheet accounts related to the revenue cycle are as follows: Accounts receivables, net: Accounts receivable, net (contract receivables) includes amounts billed under the contract terms. The amounts are stated at their net realizable value. The Company maintains an allowance for doubtful accounts to provide for the estimated number of receivables that will not be collected. The Company considers several factors in its estimate of the allowance, including knowledge of a client’s financial condition, its historical collection experience, and other factors relevant to assessing the collectability of such receivables. Contract Assets: Contract Assets are recorded when progress to completion revenue earned on contracts exceeds amounts billed under the contract. It may also include contract retainages that can be billed once contract stipulations are satisfied. Contract Liabilities: Contract Liabilities are recorded when amounts billed under a contract exceeds the progress to completion revenue earned under the contract. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could vary from the estimates and assumptions that were used. Concentration of Credit Risk and other Concentrations The Company’s financial instruments that are exposed to concentrations of credit risk consist of cash and accounts receivable. Cash balances at various times during the year may exceed the amount insured by the Federal Deposit Insurance Corporation. The Company’s cash deposits are held in institutions whose credit ratings are monitored by management, and the Company has not incurred any losses related to such deposits. The Company can, at times, be subject to a concentration of credit risk with respect to outstanding accounts receivable. However, the Company believes no such concentration existed during the three months ended March 31, 2023, or the year ended December 31, 2022. The Company’s customers are located throughout the United States. Although the Company generally grants credit without collateral, management believes that its contract acceptance, billing, and collection policies are adequate to minimize material credit risk. Also, for non-governmental customers, the Company can often place mechanics liens against the real property associated with the contract in the event of non-payment. Fair Value Measurements Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures (“ASC Topic 820”) provides the framework for measuring and reporting financial assets and liabilities at fair value. ASC Topic 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The codification establishes a three-level disclosure hierarchy to indicate the level of judgment used to estimate fair value measurements: Level 1: Quoted prices in active markets for identical assets or liabilities as of the reporting date; Level 2: Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices (such as interest rate and yield curves); Level 3: Uses inputs that are unobservable, supported by little or no market activity and reflect significant management judgment. As of March 31, 2023 and December 31, 2022: • The carrying amount of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair value due to the relatively short duration of these instruments; • The carrying amounts of debt obligations approximate their fair values as the terms are comparable to terms currently offered by local financial institutions for arrangements with similar terms to industry peers with comparable credit characteristics. Accordingly, the debt obligations involve Level 2 fair value inputs; • The liability related to shares subject to repurchase was recognized at fair value using Level 1 inputs as there is an active market for the Company’s publicly traded stock. There was no remaining liability as of December 31, 2022. For further discussion, see Note 15, Employee Stock Purchase and Stock Incentive Plans . Income Taxes The Company recognizes deferred income tax assets or liabilities for expected future tax consequences of events recognized in the consolidated financial statements or tax returns. Under this method, deferred income tax assets or liabilities are determined based upon the difference between the financial statement and income tax bases of assets and liabilities using enacted tax rates expected to apply when the differences settle or become realized. Valuation allowances are provided when it is more likely than not that a deferred tax asset is not realizable or recoverable in the future. As of March 31, 2023, no valuation allowances are required, and all deferred tax assets are realizable. The Company assesses uncertain tax positions to determine whether the position will more likely than not be sustained upon examination by the Internal Revenue Service or other taxing authorities. If the Company cannot reach a more-likely-than-not determination, no benefit is recorded. If the Company determines that the tax position is more likely than not to be sustained, the Company records the largest amount of benefit that is more likely than not to be realized when the tax position is settled. The Company recognizes interest and penalties, if any, related to uncertain tax positions in income tax expense. Beginning January 1, 2022, the Tax Cuts and Jobs Act (TCJA) of 2017 eliminated the option to deduct research and development expenditures in the current year and now requires taxpayers to capitalize and amortize research and development costs pursuant to Internal Revenue Code Section 174. The capitalized expenses are amortized over a 5-year period for domestic expenses and a 15-year period for foreign expenses. As a result of this provision of the TCJA, we have established a $16.9 million uncertain tax position related to capitalized and amortizable research and development ("R&D") costs as of the period ended March 31, 2023. The Company recognizes the effect of a change in tax rates on deferred tax assets and liabilities in income in the period that includes the enactment date. The Company’s effective tax rate for the three months ended March 31, 2023 and 2022 was (65.9)% and (8.8)%, respectively. The change in the Company’s effective tax rate is predominantly due to changes in the estimated annual effective tax rate. The most prominent factors include an increase in projected R&D credits generated for 2023, a change in the projected limitations of the deductible executive compensation, and an overall reduction in forecasted income for 2023 relative to 2022. With respect to the projected R&D credit, the Company anticipates the 2023 generated R&D credit to be $3.8 million as of March 31, 2023 as compared to the projected R&D credit to be generated for fiscal year 2022 was $2.0 million as of March 31, 2022. Similarly, the Company anticipates the annual projected limitation on the deductibility of executive compensation to be $2.4 million for 2023 as compared to $3.4 million for 2022. These factors as well as the forecasted change in book income predominantly resulted in the change in the estimated annual effective tax rate. Furthermore, the Company also recognize net discrete benefits of under $0.1 million for the three months ended March 31, 2023, as compared to net discrete benefit of $0.4 million for the three months ended March 31, 2022. The discrete benefits are predominantly the result of a windfall tax benefit for restricted stock awards and other non-recurring adjustments. More specifically, the windfall tax adjustment for restricted stock awards recognized at a value higher than the grant date fair value is $0.3 million for the three months ended March 31, 2023, and $0.4 million for the three months ended March 31, 2022. In addition, the Company recognized a one-time adjustment to the state income taxes payables, resulting in $0.2 million net discrete expense. These factors reduced the rate by 11.6% and 27.1% for the quarters ended March 31, 2023, and March 31, 2022, respectively. For year ended December 31, 2022, the Company filed Form 3115, Application for Change in Accounting Method, with the Internal Revenue Service requesting to change its method of deducting stock-based compensation expense from an impermissible method to a permissible method; on July 27, 2022, the Form 3115 was approved by the Internal Revenue Service, which will result in a reversal of a $1.9 million uncertain tax position to a deferred tax liability. In addition, the Company recorded a $0.4 million uncertain tax position during the year ended December 31, 2022, related to the annual limitation on the deductibility of executive compensation claimed on a prior period U.S. federal income tax return. The Company files income tax returns in the U.S. federal jurisdiction and certain states in which it operates. Based on the timing of the filing of certain tax returns, the Company’s federal income tax returns for tax years 2019 and thereafter remain subject to examination by the U.S. Internal Revenue Service. The statute of limitations on the Company’s state income tax returns generally conforms to the federal three-year statute of limitations. Segments The Company operates in one segment based upon the financial information used by its chief operating decision maker in evaluating the financial performance of its business and allocating resources. The single segment represents the Company’s core business of providing engineering and related professional services to its customers. Recently Issued Accounting Guidance Accounting guidance recently adopted In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”) to increase transparency and comparability of accounting for lease transactions by requiring lessees to recognize the right-of-use assets and lease liabilities on the balance sheet and to disclose qualitative and quantitative information about lease transactions and enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The Company adopted the new standard on January 1, 2022, using a modified retrospective basis and the impact of this ASU was not material. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (Topic 740), which amends certain exceptions to the general principles of ASC 740, Income Taxes , and simplifies several areas such as accounting for a franchise tax or similar tax that is partially based on income. The Company adopted the new guidance starting January 1, 2022. The impact of this ASU is reflected in the consolidated financial statements and was not material. In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326) to replace the incurred loss impairment methodology under U.S. GAAP. This ASU introduces a new accounting model, the Current Expected Credit Losses model (CECL), which could result in earlier recognition of credit losses and additional disclosures related to credit risk. The CECL model will require the Company to use a forward-looking expected credit loss impairment methodology for the recognition of credit losses for financial instruments at the time the financial asset is originated or acquired, and require a loss be incurred before it is recognized. The expected credit losses are adjusted each period for changes in expected lifetime credit losses. The new standard will apply to accounts receivable, notes, and other financial instruments. This standard is effective for the Company beginning January 1, 2023. Adoption of ASU 2016-13 will be applied using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the effective date. The Company adopted the new guidance starting January 1, 2023. The impact of this ASU is reflected in the consolidated financial statements and was not material. The Company does not believe that any recently issued standards other than those noted above would have a material effect on its consolidated financial statements.

Earnings Per Share [Abstract]
Earnings per Share	Earnings per Share Basic earnings per share is calculated by dividing net income attributable to the Company available to common stockholders by the weighted average number of common shares outstanding for the three months ended March 31, 2023 and 2022. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were either exercised or converted into common stock or resulted in the issuance of common stock that would share in the earnings of the Company. The dilutive effect of options is reflected in diluted earnings per share by application of the treasury stock method. The dilutive effect of shares to be purchased under the Company’s Employee Stock Purchase Plan is reflected in diluted earnings per share by the weighted-average number of shares outstanding that would have been outstanding during the period. The dilutive effect of convertible debt is reflected in diluted earnings per share by application of the if-converted method. The Company uses the two-class method to determine earnings per share. For calculating basic earnings per share, for the three months ended March 31, 2023, the weighted average number of shares outstanding exclude 1,750,268 non-vested restricted shares and 9,690 unexercised substantive options. The computation of diluted earnings per share for the three months ended March 31, 2023 did not assume the effect of restricted shares or substantive options because the effects were antidilutive. For calculating basic earnings per share, for the three months ended March 31, 2022, the weighted average number of shares outstanding exclude 2,080,691 non-vested restricted shares and 14,586 unexercised substantive options. The computation of diluted earnings per share for the three months ended March 31, 2022 did not assume the effect of restricted shares or substantive options because the effects were antidilutive. 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 for the three months ended March 31, 2023 and 2022 (in thousands, except share data): For the Three Months Ended March 31, 2023 2022 Numerator Net income $ 537 $ 1,457 Earnings allocated to non-vested shares 69 254 Subtotal $ 468 $ 1,203 Denominator Weighted average common shares outstanding 11,800,308 9,926,395 Effect of dilutive nominal options – – Effect of dilutive contingently earned shares 869,273 117,399 Dilutive average shares outstanding 12,669,581 10,043,794 Basic earnings per share $ 0.04 $ 0.12 Dilutive earnings per share $ 0.04 $ 0.12

Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements and footnotes of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial information. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position, changes in shareholders’ equity and cash flows. The results of operations for the current period are not necessarily indicative of the results for the full year or the results for any future periods. The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related footnotes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 filed with the SEC on March 15, 2023. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Emerging Growth Company	Emerging Growth CompanySection 102(b)(1) of the Jumpstart Our Business Startups Act (“JOBS Act”) exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Securities Exchange Act of 1934 (the “Exchange Act”)) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company that is either not an emerging growth company or, an emerging growth company that has opted out of using the extended transition period, difficult or impossible because of the potential differences in accounting standards used.

The Company adopted this standard effective January 1, 2019, the first day of the Company's fiscal year. As discussed in Note 1, the Company provides a variety of engineering and related professional services to customers located throughout the United States. The Company enters into agreements with clients that create enforceable rights and obligations and for which it is probable that the Company will collect the consideration to which it will be entitled as services transfer to the customer. It is customary practice for the Company to have written agreements with its customers and revenue on oral or implied arrangements is generally not recognized. The Company recognizes revenue based on the consideration specified in the applicable agreement. Excluded from the transaction price are amounts collected on behalf of third parties for sales and similar taxes. Long-term contracts typically contain billing terms that provide for invoicing once a month and payment on a net 30-day basis. Exceptions to monthly billing terms are to ensure that the Company performs satisfactorily rather than representing a significant financing component. For example, fixed price contracts may provide for milestone billings based upon the attainment of specific project objectives to ensure the Company meets its contractual requirements rather than having billing monthly. Additionally, contracts may include retentions or holdbacks paid at the end of a project to ensure that Company meets the contract requirements. The Company does not assess whether a contract contains a significant financing component if the Company expects, at contract inception, that the period between payment by the customer and the transfer of promised services to the customer will be less than one year. As a professional services engineering firm, the Company generally recognizes revenue over time as control transfers to a customer based upon the extent of progress towards satisfaction of the performance obligation. For services delivered under fixed price contracts, the Company uses the ratio of actual costs incurred to total estimated costs since costs incurred (an input method) which represents a reasonable measure of progress towards the satisfaction of a performance in order to estimate the portion of revenue earned. This method faithfully depicts the transfer of value to the customer when the Company is satisfying a performance obligation that entails a number of interrelated tasks or activities for a combined output that requires the Company to coordinate the work of employees and sub-consultants. Contract costs typically include direct labor, subcontract and consultant costs, materials and indirect costs related to contract performance. Changes in estimated costs to complete these obligations result in adjustments to revenue on a cumulative catch-up basis, which causes the effect of revised estimates to be recognized in the current period. Changes in estimates can routinely occur over the contract term for a variety of reasons including, changes in scope, unanticipated costs, delays or favorable or unfavorable progress than original expectations. In situations where the estimated costs to perform exceeds the consideration to be received, the Company accrues the entire estimated loss during the period the loss becomes known. When a performance obligation is billed using a time-and-material type contract, the Company measures its progress to complete based upon the hours incurred for the period times contractually agreed upon billing rates plus any materials delivered or consumed in the project. When applicable, the Company will recognize revenue under these contracts as invoiced under the practical expedient. In certain situations, it is possible that two or more contracts should be combined and accounted for as a single contract, or a single contract should be accounted for as multiple performance obligations. This requires significant judgment and could impact the amount and timing of revenue recognition. Such determinations are made using management’s best estimate and knowledge of contracts and related performance obligations. The Company’s contracts may contain variable consideration in the form of unpriced or pending change orders or claims that either increase or decrease the contract price. Variable consideration is generally estimated using the expected value method but may from time to time be estimated using the most likely amount method depending on the circumstance. Estimated amounts are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. Estimates of variable consideration are based upon historical experience and known trends. The Company recognizes claims against vendors, sub-consultants, and others as a reduction in costs when the contract establishes enforceability, and the amounts of recovery are reasonably estimable and probable. Reduction in costs are recognized at the lesser of the amount management expects to recover or costs incurred. Contract related assets and liabilities are classified as current assets and current liabilities. Significant balance sheet accounts related to the revenue cycle are as follows: Accounts receivables, net: Accounts receivable, net (contract receivables) includes amounts billed under the contract terms. The amounts are stated at their net realizable value. The Company maintains an allowance for doubtful accounts to provide for the estimated number of receivables that will not be collected. The Company considers several factors in its estimate of the allowance, including knowledge of a client’s financial condition, its historical collection experience, and other factors relevant to assessing the collectability of such receivables. Contract Assets: Contract Assets are recorded when progress to completion revenue earned on contracts exceeds amounts billed under the contract. It may also include contract retainages that can be billed once contract stipulations are satisfied. Contract Liabilities: Contract Liabilities are recorded when amounts billed under a contract exceeds the progress to completion revenue earned under the contract.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could vary from the estimates and assumptions that were used.
Concentration of Credit Risk and other Concentrations	Concentration of Credit Risk and other Concentrations The Company’s financial instruments that are exposed to concentrations of credit risk consist of cash and accounts receivable. Cash balances at various times during the year may exceed the amount insured by the Federal Deposit Insurance Corporation. The Company’s cash deposits are held in institutions whose credit ratings are monitored by management, and the Company has not incurred any losses related to such deposits. The Company can, at times, be subject to a concentration of credit risk with respect to outstanding accounts receivable. However, the Company believes no such concentration existed during the three months ended March 31, 2023, or the year ended December 31, 2022. The Company’s customers are located throughout the United States. Although the Company generally grants credit without collateral, management believes that its contract acceptance, billing, and
Fair Value Measurements	Fair Value Measurements Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures (“ASC Topic 820”) provides the framework for measuring and reporting financial assets and liabilities at fair value. ASC Topic 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The codification establishes a three-level disclosure hierarchy to indicate the level of judgment used to estimate fair value measurements: Level 1: Quoted prices in active markets for identical assets or liabilities as of the reporting date; Level 2: Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices (such as interest rate and yield curves); Level 3: Uses inputs that are unobservable, supported by little or no market activity and reflect significant management judgment. As of March 31, 2023 and December 31, 2022: • The carrying amount of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair value due to the relatively short duration of these instruments; • The carrying amounts of debt obligations approximate their fair values as the terms are comparable to terms currently offered by local financial institutions for arrangements with similar terms to industry peers with comparable credit characteristics. Accordingly, the debt obligations involve Level 2 fair value inputs; • The liability related to shares subject to repurchase was recognized at fair value using Level 1 inputs as there is an active market for the Company’s publicly traded stock. There was no remaining liability as of December 31, 2022. For further discussion, see Note 15, Employee Stock Purchase and Stock Incentive Plans .
Income Taxes	Income Taxes The Company recognizes deferred income tax assets or liabilities for expected future tax consequences of events recognized in the consolidated financial statements or tax returns. Under this method, deferred income tax assets or liabilities are determined based upon the difference between the financial statement and income tax bases of assets and liabilities using enacted tax rates expected to apply when the differences settle or become realized. Valuation allowances are provided when it is more likely than not that a deferred tax asset is not realizable or recoverable in the future. As of March 31, 2023, no valuation allowances are required, and all deferred tax assets are realizable. The Company assesses uncertain tax positions to determine whether the position will more likely than not be sustained upon examination by the Internal Revenue Service or other taxing authorities. If the Company cannot reach a more-likely-than-not determination, no benefit is recorded. If the Company determines that the tax position is more likely than not to be sustained, the Company records the largest amount of benefit that is more likely than not to be realized when the tax position is settled. The Company recognizes interest and penalties, if any, related to uncertain tax positions in income tax expense. Beginning January 1, 2022, the Tax Cuts and Jobs Act (TCJA) of 2017 eliminated the option to deduct research and development expenditures in the current year and now requires taxpayers to capitalize and amortize research and development costs pursuant to Internal Revenue Code Section 174. The capitalized expenses are amortized over a 5-year period for domestic expenses and a 15-year period for foreign expenses. As a result of this provision of the TCJA, we have established a $16.9 million uncertain tax position related to capitalized and amortizable research and development ("R&D") costs as of the period ended March 31, 2023. The Company recognizes the effect of a change in tax rates on deferred tax assets and liabilities in income in the period that includes the enactment date. The Company’s effective tax rate for the three months ended March 31, 2023 and 2022 was (65.9)% and (8.8)%, respectively. The change in the Company’s effective tax rate is predominantly due to changes in the estimated annual effective tax rate. The most prominent factors include an increase in projected R&D credits generated for 2023, a change in the projected limitations of the deductible executive compensation, and an overall reduction in forecasted income for 2023 relative to 2022. With respect to the projected R&D credit, the Company anticipates the 2023 generated R&D credit to be $3.8 million as of March 31, 2023 as compared to the projected R&D credit to be generated for fiscal year 2022 was $2.0 million as of March 31, 2022. Similarly, the Company anticipates the annual projected limitation on the deductibility of executive compensation to be $2.4 million for 2023 as compared to $3.4 million for 2022. These factors as well as the forecasted change in book income predominantly resulted in the change in the estimated annual effective tax rate. Furthermore, the Company also recognize net discrete benefits of under $0.1 million for the three months ended March 31, 2023, as compared to net discrete benefit of $0.4 million for the three months ended March 31, 2022. The discrete benefits are predominantly the result of a windfall tax benefit for restricted stock awards and other non-recurring adjustments. More specifically, the windfall tax adjustment for restricted stock awards recognized at a value higher than the grant date fair value is $0.3 million for the three months ended March 31, 2023, and $0.4 million for the three months ended March 31, 2022. In addition, the Company recognized a one-time adjustment to the state income taxes payables, resulting in $0.2 million net discrete expense. These factors reduced the rate by 11.6% and 27.1% for the quarters ended March 31, 2023, and March 31, 2022, respectively. For year ended December 31, 2022, the Company filed Form 3115, Application for Change in Accounting Method, with the Internal Revenue Service requesting to change its method of deducting stock-based compensation expense from an impermissible method to a permissible method; on July 27, 2022, the Form 3115 was approved by the Internal Revenue Service, which will result in a reversal of a $1.9 million uncertain tax position to a deferred tax liability. In addition, the Company recorded a $0.4 million uncertain tax position during the year ended December 31, 2022, related to the annual limitation on the deductibility of executive compensation claimed on a prior period U.S. federal income tax return. The Company files income tax returns in the U.S. federal jurisdiction and certain states in which it operates. Based on the timing of the filing of certain tax returns, the Company’s federal income tax returns for tax years 2019 and thereafter remain subject to examination by the U.S. Internal Revenue Service. The statute of limitations on the Company’s state income tax returns generally conforms to the federal three-year statute of limitations.

The single segment represents the Company’s core business of providing engineering and related professional services to its customers.
Recently Issued Accounting Guidance	Recently Issued Accounting Guidance Accounting guidance recently adopted In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”) to increase transparency and comparability of accounting for lease transactions by requiring lessees to recognize the right-of-use assets and lease liabilities on the balance sheet and to disclose qualitative and quantitative information about lease transactions and enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The Company adopted the new standard on January 1, 2022, using a modified retrospective basis and the impact of this ASU was not material. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (Topic 740), which amends certain exceptions to the general principles of ASC 740, Income Taxes , and simplifies several areas such as accounting for a franchise tax or similar tax that is partially based on income. The Company adopted the new guidance starting January 1, 2022. The impact of this ASU is reflected in the consolidated financial statements and was not material. In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326) to replace the incurred loss impairment methodology under U.S. GAAP. This ASU introduces a new accounting model, the Current Expected Credit Losses model (CECL), which could result in earlier recognition of credit losses and additional disclosures related to credit risk. The CECL model will require the Company to use a forward-looking expected credit loss impairment methodology for the recognition of credit losses for financial instruments at the time the financial asset is originated or acquired, and require a loss be incurred before it is recognized. The expected credit losses are adjusted each period for changes in expected lifetime credit losses. The new standard will apply to accounts receivable, notes, and other financial instruments. This standard is effective for the Company beginning January 1, 2023. Adoption of ASU 2016-13 will be applied using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the effective date. The Company adopted the new guidance starting January 1, 2023. The impact of this ASU is reflected in the consolidated financial statements and was not material. The Company does not believe that any recently issued standards other than those noted above would have a material effect on its consolidated financial statements.
