Gexcon US Inc.

Gexcon US Inc., a foreign-owned, for-profit organization headquartered in Bethesda, Maryland, delivers computational fluid dynamics software, software maintenance and support services, and expert witness consulting to federal civilian agencies as a prime contractor. Gexcon operates exclusively on full-and-open purchase orders with no set-aside designations, competing across NAICS 541712 (Software Publishers), 541330 (Engineering Services), and PSC codes for software licenses, maintenance, and expert services.

Gexcon's federal customer base centers on three agencies accounting for 93% of recent awards. The Federal Energy Regulatory Commission leads with six awards and $591 thousand in combined potential value, anchored by FLACS software maintenance and support contracts. The Department of Transportation's Pipeline and Hazardous Materials Safety Administration has placed two awards totaling $413 thousand, including a $396.5 thousand purchase order in February 2024 for six FLACS single-seat regional WAN licenses and a $16 thousand order in November 2025 for an annual FLACS-CFD software license. The Department of Justice's Environment and Natural Resources Division has awarded two purchase orders totaling $163 thousand for expert witness services on a time-and-materials basis. Additional work spans the Department of Labor's Occupational Safety and Health Administration and the Bureau of Alcohol, Tobacco, Firearms and Explosives, each with one award.

Gexcon's capability portfolio is highly specialized. The vendor develops and distributes FLACS (Flame Acceleration Simulator), a computational fluid dynamics software platform used for hazard analysis, gas dispersion simulation, and explosion scenario modeling. Work includes perpetual software licenses (four awards), annual maintenance and support contracts (two awards), and expert witness consulting (five awards). Recent prime awards include a $95.5 thousand FERC purchase order for FLACS maintenance and support running through September 2029; a $44.8 thousand Department of Justice expert witness services order with completion in February 2031; and the $396.5 thousand PHMSA regional WAN license order.

Activity has remained sparse and episodic across the five-year window — one award in 2018, two in 2023, one in 2024, one in 2025, and two in 2026 — with combined potential value across all fourteen recent awards totaling $1.3 million and $792 thousand already obligated. Two awards carrying $134 thousand in combined potential value face ultimate completion within the next twenty-four months, creating limited near-term recompete exposure. Gexcon holds no parent contract vehicles or IDVs and operates as a 100% prime contractor footprint with no subcontract activity in the source data.
