Joiner Fire Sprinkler Co Inc.

Joiner Fire Sprinkler Co Inc., a Black American–owned, minority-owned small disadvantaged business headquartered in Birmingham, Alabama, operates exclusively as a subcontractor on federal construction and fire protection projects. The vendor has received three sub-awards totaling $1.2 million across the past eighteen months, all from a single prime contractor (BL Harbert International LLC) on Department of Defense and Army Corps of Engineers projects.

Joiner's subcontract work centers on fire protection systems installation and design support within military construction programs. The three named sub-awards span an F-35 aircraft maintenance hangar construction at Ebbing Field Air National Guard Base in Fort Smith, Arkansas (awarded June 2026); a design-build project at the National Security & Intelligence Center of Excellence (awarded April 2025); and a base proposal plus options contract in Birmingham, Alabama (awarded February 2026). All three awards fall under NAICS 236220 (Commercial and Institutional Building Construction). Customer concentration runs across three distinct federal agencies — the FBI Headquarters Division, the Army Corps of Engineers Engineering District Louisville, and the Army Corps of Engineers Engineering District Little Rock — though the small award count limits any meaningful concentration analysis. The vendor does not appear in available federal contract IDV or vehicle data, indicating work flows through traditional competitive solicitations rather than established government-wide acquisition vehicles or BPAs.

Activity trajectory is minimal but accelerating: one award in 2025 and two in 2026. Service Contract Inventory records show Joiner reported roughly 1.2 FTEs on federal service contracts in FY2024 and 3.2 FTEs in FY2025 across two SCI-reportable sub-contracts above the $150,000 threshold; SCI captures only a subset of the vendor's federal activity and does not reflect total enterprise revenue. The vendor operates exclusively through BL Harbert International LLC as the prime contractor — no prime contract awards, parent vehicles, or teaming with other primes are present in the source data. This positioning places Joiner in the role of a specialty subcontractor for fire protection scope within larger defense construction programs, with limited independent federal procurement exposure and no documented incumbent base on government-wide vehicles.
