Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | Note 1 — Organization and Plan of Business Operations 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 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 “Acquisition Date” or the “Closing Date”), 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 FdG HVAC, LLC (“FdG”), as stockholders’ representative (the “Merger Agreement”). In connection with the closing of the Business Combination, the Company changed its name from 1347 Capital Corp. to Limbach Holdings, Inc. See Note 4 – Business Combination for further discussion. Through these entities, 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 services. 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.
