Lang Constructors Inc.

Lang Constructors Inc., a small business based in Flint, Michigan, provides federal facility repair, alteration, and renovation services to civilian agencies as a prime contractor under Total Small Business set-asides. The company operates exclusively on GSA Region 5 IDIQ vehicles covering the six-state Midwest region (Illinois, Indiana, Michigan, Minnesota, Ohio, Wisconsin) and competes predominantly under small-business set-asides on delivery orders and purchase orders for interior and exterior building work, electrical and data infrastructure, security upgrades, and site improvements.

Lang Constructors' customer base is heavily concentrated with the General Services Administration Public Buildings Service Region 5, which represents 76 percent of awards and 96 percent of combined potential value across its recent footprint. The GSA R5 concentration reflects the vendor's two primary contract vehicles: the GSA R5 Regional Construction IDIQ (awarded September 2024, $50 million ceiling, Total Small Business set-aside, running through November 2026) and the Repair and Alterations MI-MN-WI 2019 IDIQ (19 task orders, approximately $1 million combined potential value). Secondary customers include the Administrative Office of the U.S. Courts (3 awards, $972 thousand), Immigration and Customs Enforcement (2 awards, $631 thousand), and the National Park Service Midwest Region (1 award, $258 thousand). Across all named customers, Lang Constructors has served twelve distinct federal agencies since 2019.

Representative work under the current GSA R5 Regional Construction IDIQ includes a $758,064.65 delivery order from the Administrative Office of the U.S. Courts (January 2026) for circuit court library renovation and modification at the Theodore Levin U.S. Courthouse in Detroit, Michigan; a $908,141.20 delivery order from GSA Public Buildings Service (January 2026) for facade, stone, and parapet wall repairs at a federal building in Flint, Michigan; a $489,947.36 delivery order from Immigration and Customs Enforcement (September 2026) for security upgrades at the ICE Homeland Security Investigation facility in Grand Rapids, Michigan; and orders from the Department of Veterans Affairs for PIV room renovations and from Customs and Border Protection for corridor signage, electrical outlets, and data cabling installation at the Rosa Parks Federal Building. Under the Repair and Alterations MI-MN-WI 2019 IDIQ, work has included ballistic window installation at the Kalamazoo Post Office and U.S. Courthouse, break shelters replacement and electrical upgrades at the Hart-Dole-Inouye Federal Center in Battle Creek, parking lot resurfacing at the Flint Federal Courthouse, and interior space renovations across multiple federal courthouse and administrative buildings in the region.

Activity has been episodic rather than trending — five awards in 2020, eight awards in 2023, eight in 2024, three in 2025, and four through September 2026 — with combined potential value across all 29 prime awards reaching $92.4 million but only $4.9 million obligated (5 percent). The recompete cliff is modest: five awards with ultimate completion dates in the next twenty-four months carry combined potential value of $3.6 million. Lang Constructors operates entirely as a prime contractor and carries no subcontractor relationships in its federal footprint; SCI reporting shows minimal service-contract invoicing ($5 thousand in FY2024) and reflects the vendor's orientation toward facility construction and repair delivery orders rather than staffing-intensive service contracts above the SCI reporting threshold. The vendor's work is concentrated in commercial and institutional building construction (28 of 29 awards under NAICS 236220) with a single pavement project (NAICS 237310) at Indiana Dunes National Park.
