Gallatin Airport Authority

Gallatin Airport Authority, doing business as Gallatin Field Airport, is a U.S. local government entity and airport authority that receives federal grant funding from the Department of Transportation Federal Aviation Administration to design, construct, and rehabilitate airport infrastructure at Bozeman Yellowstone International Airport in Belgrade, Montana. The authority acts exclusively as a prime recipient on all federal awards and does not subcontract federal work.

Gallatin Airport Authority's federal footprint is dominated by FAA Airport Improvement Program (CFDA 20.106) and Airport Terminal Program (CFDA 20.118) grants supporting multi-phase terminal expansion and airfield infrastructure modernization at the regional airport serving Bozeman. Recent awards fund concrete construction and engineering work: a $12.1 million Terminal Program grant (July 2026) for Phase 2 building interiors and systems on a 257,080-square-foot terminal expansion; a $3.2 million Airport Improvement Program grant (August 2026) for Phase 3 terminal construction; a $4.4 million grant (June 2026) to construct two new commercial aprons (10,400 square yard concrete and 13,500 square yard asphalt); and a $5.6 million grant (August 2025) for Phase 2 airfield work including taxiway construction and runway extension. Additional recent work includes $10.5 million (May 2025) for terminal Phase 1 engineering and site preparation, $8.4 million (June 2026) for taxiway extension, and $833 thousand (May 2025) for runway grading and gravel placement. The authority also manages smaller formula grants for equipment acquisition—$1.4 million (August 2024) for snow removal equipment and $450 thousand (September 2023) for contract tower modifications—and environmental planning grants, including $750 thousand (August 2023) for environmental impact assessment of proposed runway improvements.

The Department of Transportation Federal Aviation Administration Northwest Mountain Region represents the dominant funding source; the top five customer agencies account for 52% of awards by count and 53% of combined potential value. The General Services Administration Public Buildings Service ranks second with $6.6 million across 15 awards, followed by the Department of Homeland Security Transportation Security Administration with $2.8 million across five awards. Awards span 142 grants with combined potential value of $17.8 million and combined obligations of $200.5 million, reflecting reimbursement-phase grants tied to previously completed or ongoing infrastructure work. Nearly all work is coded to NAICS 531110 (Lessors of Nonresidential Buildings), with primary PSC coverage under Lease/Rental of Office Buildings (44 awards). The authority holds a GSA Basic Ordering Agreement (GS08B13986) with 80 task orders valued at $13.6 million combined potential value, primarily supporting facility leasing arrangements. Three awards reach completion within the next twenty-four months; most terminal and airfield grants carry ultimate completion dates through 2029 and 2030, with performance extending across Montana.
