Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Limbach Holdings, Inc. (the “Company” or “Successor”), formerly known as 1347 Capital Corp. (“1347 Capital”), is a Delaware corporation headquartered in Pittsburgh, Pennsylvania. The Company’s Condensed Consolidated Financial Statements include the accounts of Limbach Holdings, Inc. and its wholly owned subsidiaries, including Limbach Holdings LLC (“LHLLC”), Limbach Facility Services LLC, Limbach Company LLC, Limbach Company LP, Harper Limbach LLC and Harper Limbach Construction LLC. The Company was originally incorporated as a special purpose acquisition company, formed for the purpose of effecting a merger, equity interest exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. On July 20, 2016, the Company consummated a business combination (“Business Combination”) with LHLLC pursuant to the agreement and plan of merger dated as of March 23, 2016, by and among 1347 Capital Corp. (now Limbach Holdings, Inc.), LHLLC and F d d We operate our business in two segments, (i) Construction, in which we generally manage large construction or renovation projects that involve primarily HVAC, plumbing and electrical services, and (ii) Service, in which we provide maintenance or service primarily on HVAC, plumbing or electrical systems. This work is primarily performed under fixed price, modified fixed price, and time and material contracts over periods of typically less than two years. The Company's customers operate in several different industries, including healthcare, education, government, commercial, manufacturing, entertainment, and leisure. The Company operates primarily in the Northeast, Mid-Atlantic, Southeast, Midwest, and Southwestern regions of the United States. Emerging Growth Company Section 102(b)(1) of the 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 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 Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Note 2 — Significant Accounting Policies Predecessor and Successor Financial Statements The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with instructions to the Quarterly Report on Form 10-Q and Rule 8-03 of Regulation S-X for smaller reporting companies. Consequently, certain information and note disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading. Readers of this report should refer to the consolidated financial statements and the notes thereto included in our latest Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”). The Condensed Consolidated Financial Statements and certain note presentations separate the Company’s presentations into two distinct periods, the period up to and including the Business Combination closing date (labeled “Predecessor”) and the period after that date (labeled “Successor”), to indicate the application of different bases of accounting between the periods presented. The accompanying Condensed Consolidated Financial Statements include a black line division which indicates that the Predecessor and Successor reporting entities shown are not comparable. The period presented from January 1, 2017 through June 30, 2017 and at December 31, 2016 are the “Successor” periods. The period presented from January 1, 2016 through June 30, 2016 is the “Predecessor” period. Unaudited Interim Financial Information The accompanying interim Condensed Consolidated Balance Sheet as of June 30, 2017, the Condensed Consolidated Statements of Operations, Condensed Consolidated Statement of Stockholders’ Equity and the Condensed Consolidated Statements of Cash Flows for the periods presented are unaudited. Also, within the notes to the Condensed Consolidated Financial Statements, we have included unaudited information for these interim periods. These unaudited interim Condensed Consolidated Financial Statements have been prepared in accordance with GAAP. In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments (consisting only of a normal recurring nature) necessary for a fair statement of the Company’s financial position as of June 30, 2017, and its results of operations and its cash flows for the three and six months ended June 30, 2017 (Successor) and June 30, 2016 (Predecessor). The results for the three and six months ended June 30, 2017 are not necessarily indicative of the results to be expected for the year ending December 31, 2017. The Successor Condensed Consolidated Balance Sheet as of December 31, 2016 was derived from audited financial statements, but does not contain all of the footnote disclosures from the annual financial statements. Revenues from fixed price and modified fixed price contracts are recognized on the percentage-of-completion method, measured by the relationship of total cost incurred to total estimated contract costs (cost-to-cost method). Revenues from time and materials contracts are recognized as services are performed. Contract revenue for long-term construction contracts is based upon management's estimate of contract values at completion, including revenue for additional work on which the contract value has not been finalized (claims) but is considered probable. Changes in job performance, job conditions, and estimated profitability, including those arising from contract penalty provisions and final contract settlements, may result in revisions to estimated costs and income, and are recognized in the period in which the revisions are determined. Provisions for estimated losses on uncompleted contracts are recognized in the period in which such losses are determined. Contract costs include direct labor, material, and subcontractor costs, and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs, depreciation, and insurance. Total estimated contract costs are based upon management's current estimate of total costs at completion. The Company recognizes revenues from its service segment contracts as these services are performed. There are two basic types of service contracts: fixed price service contracts which are signed in advance for maintenance, repair, and retrofit work over a period of typically one year, and service contracts not signed in advance for similar maintenance, repair, and retrofit work performed on an as-needed basis. Fixed price service contracts are generally performed evenly over the contract period, and accordingly, revenue is recognized on a pro rata basis over the life of the contract. Revenues derived from other service contracts are recognized when the services are performed. Expenses related to all service contracts are recognized as services are provided. Costs and estimated earnings in excess of billings on uncompleted contracts reflected in the consolidated balance sheets arise when revenues have been recognized but the amounts cannot be billed under the terms of the contracts. Also included in costs and estimated earnings on uncompleted contracts are amounts the Company seeks or will seek to collect from customers or others for errors or changes in contract specifications or design, contract change orders in dispute or unapproved as to scope and price, or other customer-related causes of unanticipated additional contract costs (claims and unapproved change orders). Such amounts are recorded at estimated net realizable value when realization is probable and can be reasonably estimated. No profit is recognized on the construction costs incurred in connection with claim amounts. Claims and unapproved change orders made by the Company may involve negotiation and, in rare cases, litigation. Unapproved change orders and claims also involve the use of estimates, and it is reasonably possible that revisions to the estimated recoverable amounts of recorded claims and unapproved change orders may be made in the near term. Claims against the Company are recognized when a loss is considered probable and amounts are reasonably determinable. Billings in excess of costs and estimated earnings on uncompleted contracts represent billings in excess of revenues recognized. In accordance with industry practice, we classify as current all assets and liabilities relating to the performance of contracts. The terms of our contracts generally range from six months to two years. Selling, general, and administrative costs are charged to expense as incurred. Bidding and proposal costs are also recognized as an expense in the period in which such amounts are incurred.

Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Note 3 – Accounting Standards Recent Accounting Pronouncements The effective dates shown in the following pronouncements are private company effective dates, based upon the Company’s election to conform to private company effective dates based on the relief provided to Emerging Growth Companies (“EGC”) under the JOBS Act. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers—Topic 606,” which supersedes the revenue recognition requirements in FASB Accounting Standard Codification (“ASC”) 605. The new guidance established principles for reporting revenue and cash flows arising from an entity’s contracts with customers. This new revenue recognition standard will replace most of the recognition guidance within GAAP. This guidance was deferred by ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, issued by the FASB in August 2015, which deferred the effective date of ASU 2014-09 from annual and interim periods beginning after December 15, 2017 to annual and interim periods beginning after December 15, 2018. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers: Principal versus Agent Considerations, which further clarifies the implementation guidance in ASU 2014-09. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, to expand the guidance on identifying performance obligations and licensing within ASU 2014-09. In May 2016, the FASB issued ASU 2016-12, Revenues from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients, which amends the guidance in the new revenue standard on collectability, noncash consideration, presentation of sales tax, and transition. The amendments are intended to address implementation issues that were raised by stakeholders and provide additional practical expedients to reduce the cost and complexity of applying the new revenue standard. The guidance can be applied on a full retrospective or modified retrospective basis whereby the entity records a cumulative effect of initially applying this update at the date of initial application. In December 2016, the FASB issued ASU 2016-20, “Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers” intended to clarify the codification or to correct unintended application of guidance which clarifies the definition of loan guarantee fees, what should be considered in contract costs impairment testing, a requirement that provisions for losses on construction-type and production-type contracts be determined at the least at the contract level, exclusion of insurance contracts from scope, specific disclosures regarding remaining performance obligations, disclosure of prior-period performance obligations and gives an example of contract modifications. These standards are effective for fiscal years beginning after December 15, 2018, including interim periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company has not yet commenced its analysis of this standard or selected the basis on which it will be applied, and therefore cannot estimate the impact of its adoption on the Condensed Consolidated Financial Statements. Beginning in the third quarter of 2017, we will commence a process to evaluate the impact of the new pronouncement on our contracts, including identifying potential differences that would result from applying the requirements of the new guidance. We will also review our various types of revenue arrangements, draft accounting policies and evaluate the new disclosure requirements on our business processes, controls and systems. In February 2016, FASB issued ASU No. 2016-02, “Leases (Topic 842),” ASU 2016-02 provides an approach for classifying leases as either finance leases or operating leases. For either classification, a right-of-use asset and a lease liability will be required to be recognized, unless the term of the lease is one year or less. The guidance is required to be applied using a modified retrospective approach which includes optional practical expedients. It is effective for annual periods beginning after December 15, 2019, and for interim periods within fiscal years beginning after December 15, 2020. Earlier application is permitted. The Company has not yet commenced its analysis of this standard and therefore cannot estimate the impact of its adoption on the Condensed Consolidated Financial Statements. In March 2016, the FASB issued ASU 2016-09, “Compensation—Stock Compensation: Improvements to Employee Share-Based Payment Accounting” to simplify accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The guidance is effective for financial statements issued for annual periods beginning after December 15, 2017, and for interim periods within fiscal years beginning after December 15, 2018. The Company is currently evaluating this standard to determine the impact of its adoption on the Condensed Consolidated Financial Statements. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments” to address diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The guidance is effective for financial statements issued for annual periods beginning after December 15, 2018, and for interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. The amendments should be applied using a retrospective transition method to each period presented. The Company is currently evaluating this standard to determine the impact of its adoption on the Condensed Consolidated Financial Statements. In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows: Restricted Cash” to address diversity in practice in the classification and presentation of changes in restricted cash on the statement of cash flows. The guidance is effective for financial statements issued for annual periods beginning after December 15, 2018, and for interim periods beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the year that includes that interim period. The Company is currently evaluating this standard to determine the impact on the Consolidated Financial Statements. In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business” to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments provide a screen to determine when a set of assets and activities is not a business. If the screen is not met, the amendments require further consideration of inputs, substantive processes and outputs to determine whether the transaction is an acquisition of a business. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2018, and for interim periods within annual periods beginning after December 15, 2019. The amendments in this update are to be applied prospectively on or after the effective date. The Company is currently evaluating this standard to determine the impact on its Consolidated Financial Statements. Also, in January 2017, the FASB issued ASU 2017-03, “Accounting Changes and Error Corrections (Topic 250) and Investments–Equity Method and Joint Ventures (Topic 323)” which applies to ASU 2014-09 and ASU 2016-02 and provides an SEC staff view that a Company evaluate ASUs not yet adopted to determine the appropriate financial statement disclosures about the potential material impacts of those ASUs on the financial statements when adopted in a future period according to Staff Accounting Bulletin (“SAB”) Topic 11.M. If the Company does not know or cannot reasonably estimate the impact that adoption of the ASU is expected to have on the financial statements, a statement should be made to that effect and additional qualitative financial statement disclosures should be made to assist the financial statement reader in assessing the significance of the impact that the standard will have on the financial statements when adopted. This guidance was effective upon issuance and has been adopted. In January 2017, the FASB issued ASU 2017-04, “Intangibles–Goodwill and Other - Simplifying the Test for Goodwill Impairment” to address the cost and complexity of the goodwill impairment test which resulted in the elimination of Step 2 from the goodwill impairment test. Step 2 measured a goodwill impairment loss by comparing the implied fair value of goodwill by assigning fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. Rather, the Company would be required to do its annual and interim goodwill impairment tests by comparing the fair value of the reporting unit with its carrying amount and to recognize an impairment charge for the amount by which the carrying amount is greater than the reporting unit’s fair value, not to exceed the total amount of goodwill allocated to that reporting unit. Income tax effects measuring the goodwill impairment loss, if applicable, from any tax deductible goodwill on the carrying amount on the reporting unit should also be considered. The guidance is effective for financial statements issued for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2021. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017.

The new senior credit facility consists of a $ 25.0 24.0 July 20, 2021 750,000 June 30, 2018 900,000 1,865,000 4.80 The Credit Agreement includes restrictions on, among other things and subject to certain exceptions, the Company and its subsidiaries’ ability to incur additional indebtedness, pay dividends or make other distributions, redeem or purchase capital stock, make investments and loans and enter into certain transactions, including selling assets, engaging in mergers or acquisitions and entering into transactions with affiliates. The Credit Agreement requires that the Company comply with certain financial performance covenants including total leverage, senior leverage, fixed charges and tangible net worth. As of June 30, 2017, the Company was in compliance with these covenants under the Credit Agreement. Mandatory prepayments are required upon the occurrence of certain events, including, among other things and subject to certain exceptions, equity issuances, changes of control of the Company, certain debt issuances, assets sales and excess cash flow. Commencing with the fiscal year ending December 31, 2017, the Company will be required to remit an amount equal to 50% of its excess cash flow (as defined in the Credit Agreement), which percentage will be reduced based on the Senior Leverage Ratio (as defined therein). The Company may voluntarily prepay the loans at any time subject to the limitations set forth in the Credit Agreement. The equity interests of the Company’s subsidiaries have been pledged as security for the obligations under the Credit Agreement. The Credit Agreement includes customary events of default, including, among other items, payment defaults, cross-defaults to other indebtedness, a change of control default and events of default with respect to certain material agreements. Additionally, with respect to the Company, an event of default occurs if the Company’s securities cease to be registered with the SEC pursuant to Section 12(b) of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”). In case of an event of default, the administrative agent would be entitled to, among other things, accelerated payment of amounts due under the new senior credit facility, foreclose on the equity of the Company’s subsidiaries, and exercise all rights of a secured creditor on behalf of the lenders. The additional margin applied to both the revolver and term loan is determined based on levels achieved under the Company’s Senior Leverage Ratio covenant, which reflects the ratio of indebtedness divided by EBITDA for the most recently ended four quarters.

Outstanding borrowings bore interest at 16.0%, with 13.0% payable quarterly in cash, and the Company had the option either to pay the remaining 3.0% in cash or have it deferred and capitalized into the Subordinated Loan balance. On December 21, 2016, the Company repaid all amounts outstanding under the Subordinated Loan Agreement in full settlement thereof, including deferred interest and prepayment penalties, totaling $15.3 million, with the proceeds of the Company’s public offering of 1,405,500 shares of its common stock at a price of $13.50 per share.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	Note 11 - Fair Value Measurements Accounting guidance defines fair value as the exit price associated with the sale of an asset or transfer of a liability in an orderly transaction between market participants at the measurement date. Under this guidance, valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. In addition, this guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The Company classifies and discloses assets and liabilities carried at fair value in one of the following three categories: • Level 1 — quoted prices (unadjusted) in active markets for identical assets and liabilities; • Level 2 — inputs other than quoted prices included within Level 1 that are observable, either directly or indirectly, or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and • Level 3 — significant unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The Company believes that the carrying amounts of its financial instruments, including cash and cash equivalents, trade accounts receivable and accounts payable consist primarily of instruments without extended maturities, which approximate fair value primarily due to their short-term maturities and low risk of counterparty default. As of June 30, 2017, the Company determined the fair value of its senior credit facility term loan at $ 19.1

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	Note 14 – Operating Segments The Company determined its operating segments on the same basis that it assesses performance and makes operating decisions. The Company manages and measures the performance of its business in two distinct operating segments: Construction and Service. These segments are reflective of how the Company's Chief Operating Decision Maker ("CODM") reviews operating results for the purposes of allocating resources and assessing performance. The Company's CODM is comprised of its Chief Executive Officer, Chief Financial Officer and Chief Operating Officer. The accounting policies of the segments are the same as those described in the summary of significant accounting policies. The CODM evaluates performance based on income from operations of the respective segments after the allocation of Corporate office operating expenses. Transactions between segments are eliminated in consolidation. Our Corporate department provides general and administrative support services to our two operating segments. The CODM allocates costs between segments for selling, general and administrative expenses and depreciation expense. All of the Company’s identifiable assets are located in the United States, which is where the Company is domiciled. The Company does not have sales outside the United States. The Company does not identify capital expenditures and total assets, including goodwill, by segment in its internal financial reports due in part to the shared use of a centralized fleet of vehicles and specialized equipment. Interest expense is not allocated to segments because of the corporate management of debt service including interest.

Commitments and Contingencies Disclosure [Text Block]	Note 15 – Commitments and Contingencies Leases 1.1 2.1 Capital leases consist primarily of leases for vehicles (see Note 8 – Debt). The leases are collateralized by the vehicles and require monthly payments of principal and interest. All leases transfer title at lease end for a nominal cash buyout. Legal. Energy Contracts 84 42 Under the terms of these energy contracts, the Company provides a guarantee bond to its customers in the amount of the guaranteed savings. The Company also maintains a Service Maintenance Agreement on most of the contracts so it can ensure proper maintenance of the equipment. On contracts without a Service Maintenance Agreement, the Company has no obligation for the guarantee if the equipment is not properly maintained. From the inception of these contracts in 1997 through June 30, 2017, the Company has not been required to make any material payments for unmet energy savings under any of the contracts. As a result of the guarantee bonds and its experience with these arrangements, the Company does not expect to incur any material liabilities with respect to the contracts. Accordingly, no liability has been recorded for the contract guarantees. Surety. 85.4 Collective Bargaining Agreements. Many of the Company’s craft labor employees are covered by collective bargaining agreements. The agreements require the Company to pay specified wages, provide certain benefits and contribute certain amounts to multi-employer pension plans. If the Company withdraws from any of the multi-employer pension plans or if the plans were to otherwise become underfunded, the Company could incur additional liabilities related to these plans. Although the Company has been informed that some of the multi-employer pension plans to which it contributes have been classified as “critical” status, the Company is not currently aware of any significant liabilities related to this issue.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Predecessor and Successor Financial Statements The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with instructions to the Quarterly Report on Form 10-Q and Rule 8-03 of Regulation S-X for smaller reporting companies. Consequently, certain information and note disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading. Readers of this report should refer to the consolidated financial statements and the notes thereto included in our latest Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”). The Condensed Consolidated Financial Statements and certain note presentations separate the Company’s presentations into two distinct periods, the period up to and including the Business Combination closing date (labeled “Predecessor”) and the period after that date (labeled “Successor”), to indicate the application of different bases of accounting between the periods presented. The accompanying Condensed Consolidated Financial Statements include a black line division which indicates that the Predecessor and Successor reporting entities shown are not comparable. The period presented from January 1, 2017 through June 30, 2017 and at December 31, 2016 are the “Successor” periods. The period presented from January 1, 2016 through June 30, 2016 is the “Predecessor” period.
Unaudited Interim Financial Information [Policy Text Block]	Unaudited Interim Financial Information The accompanying interim Condensed Consolidated Balance Sheet as of June 30, 2017, the Condensed Consolidated Statements of Operations, Condensed Consolidated Statement of Stockholders’ Equity and the Condensed Consolidated Statements of Cash Flows for the periods presented are unaudited. Also, within the notes to the Condensed Consolidated Financial Statements, we have included unaudited information for these interim periods. These unaudited interim Condensed Consolidated Financial Statements have been prepared in accordance with GAAP. In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments (consisting only of a normal recurring nature) necessary for a fair statement of the Company’s financial position as of June 30, 2017, and its results of operations and its cash flows for the three and six months ended June 30, 2017 (Successor) and June 30, 2016 (Predecessor). The results for the three and six months ended June 30, 2017 are not necessarily indicative of the results to be expected for the year ending December 31, 2017. The Successor Condensed Consolidated Balance Sheet as of December 31, 2016 was derived from audited financial statements, but does not contain all of the footnote disclosures from the annual financial statements.
Revenue Recognition, Policy [Policy Text Block]	Revenues and Cost Recognition Revenues from fixed price and modified fixed price contracts are recognized on the percentage-of-completion method, measured by the relationship of total cost incurred to total estimated contract costs (cost-to-cost method). Revenues from time and materials contracts are recognized as services are performed. Contract revenue for long-term construction contracts is based upon management's estimate of contract values at completion, including revenue for additional work on which the contract value has not been finalized (claims) but is considered probable. Changes in job performance, job conditions, and estimated profitability, including those arising from contract penalty provisions and final contract settlements, may result in revisions to estimated costs and income, and are recognized in the period in which the revisions are determined. Provisions for estimated losses on uncompleted contracts are recognized in the period in which such losses are determined. Contract costs include direct labor, material, and subcontractor costs, and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs, depreciation, and insurance. Total estimated contract costs are based upon management's current estimate of total costs at completion. The Company recognizes revenues from its service segment contracts as these services are performed. There are two basic types of service contracts: fixed price service contracts which are signed in advance for maintenance, repair, and retrofit work over a period of typically one year, and service contracts not signed in advance for similar maintenance, repair, and retrofit work performed on an as-needed basis. Fixed price service contracts are generally performed evenly over the contract period, and accordingly, revenue is recognized on a pro rata basis over the life of the contract. Revenues derived from other service contracts are recognized when the services are performed. Expenses related to all service contracts are recognized as services are provided. Costs and estimated earnings in excess of billings on uncompleted contracts reflected in the consolidated balance sheets arise when revenues have been recognized but the amounts cannot be billed under the terms of the contracts. Also included in costs and estimated earnings on uncompleted contracts are amounts the Company seeks or will seek to collect from customers or others for errors or changes in contract specifications or design, contract change orders in dispute or unapproved as to scope and price, or other customer-related causes of unanticipated additional contract costs (claims and unapproved change orders). Such amounts are recorded at estimated net realizable value when realization is probable and can be reasonably estimated. No profit is recognized on the construction costs incurred in connection with claim amounts. Claims and unapproved change orders made by the Company may involve negotiation and, in rare cases, litigation. Unapproved change orders and claims also involve the use of estimates, and it is reasonably possible that revisions to the estimated recoverable amounts of recorded claims and unapproved change orders may be made in the near term. Claims against the Company are recognized when a loss is considered probable and amounts are reasonably determinable. Billings in excess of costs and estimated earnings on uncompleted contracts represent billings in excess of revenues recognized. In accordance with industry practice, we classify as current all assets and liabilities relating to the performance of contracts. The terms of our contracts generally range from six months to two years. Selling, general, and administrative costs are charged to expense as incurred. Bidding and proposal costs are also recognized as an expense in the period in which such amounts are incurred.
