About Lang Constructors Inc.
Lang Constructors Inc., a Flint, Michigan–based for-profit construction company, delivers federal facility repair, alteration, and renovation services as a prime contractor under Total Small Business set-asides and full-and-open competition, with 100% of its recent award footprint held as prime work.
The company operates primarily under two GSA Region 5 IDIQ vehicles: the $50 million GSA R5 Regional Construction IDIQ awarded in September 2024 under Total Small Business set-aside, covering repair and alterations across Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin through November 2026; and the Repair and Alterations MI-MN-WI 2019 vehicle, which supplied 19 task orders worth $997 thousand in combined potential value. Capability scope centers on interior and exterior renovations, HVAC upgrades, electrical work, plumbing, fire systems, and related construction activities. Recent representative work includes a $752,068 circuit court library renovation with modifications at the Theodore Levin U.S. Courthouse in Detroit (Administrative Office of the U.S. Courts, January 2026), a $908,141 facade repair project at a federal building in Flint (GSA Region 5, January 2026), a $145,381 transformer replacement at the Cargo Inspection Facility in Detroit (GSA Region 5, March 2026), a $257,777 pavement and site improvements contract at Indiana Dunes National Park (National Park Service, March 2023), and ballistic window installation at the Kalamazoo Post Office and U.S. Courthouse (U.S. Marshals Service, September 2024).
Customer concentration sits heavily with GSA Region 5 Public Buildings Service, which accounts for 15 awards and $88.1 million in combined potential value (97% of the portfolio), followed by the Administrative Office of the U.S. Courts with 3 awards and $966 thousand. The portfolio covers work for 12 distinct agencies, though the Regional Construction vehicles absorb the majority of ordering activity. Lang Constructors also performs on the Repair and Alterations MI-MN-WI 2019 vehicle for the Defense Logistics Agency, U.S. Marshals Service, Social Security Administration, National Labor Relations Board, and U.S. Customs and Border Protection, among other civilian agencies.
Activity shows an uneven trajectory across the award snapshot: five awards in 2020, eight in 2023, eight in 2024, three in 2025, and three in the first quarter of 2026. The company's recent footprint reflects active ordering against the newer GSA R5 IDIQ (awarded September 2024), which carries a two-year completion horizon through November 2026. Within the next twenty-four months, four awards worth $2 million in combined potential value reach ultimate completion, representing modest recompete exposure. SCI-reportable invoicing captured only $5 thousand in FY2024 across one prime record — a data reflection that typical facility repair and alteration projects fall below or substantially below the $150,000 SCI reporting threshold, or are structured as firm-fixed-price delivery orders that do not trigger labor-hour-based SCI reporting. The company operates 100% as a prime contractor with no subcontract engagement in the award record. Regional focus on GSA facilities in the Midwest, combined with Total Small Business set-aside positioning on the newer IDIQ and full-and-open competition on task orders from the 2019 vehicle, positions Lang Constructors as a regional repair and alterations contractor with deep GSA Region 5 penetration.
