GRA Inc.

GRA Inc., doing business as Gellman Research Associates, provides aviation economics consulting and specialized research services to federal agencies as a prime contractor (100% of recent awards), competing full-and-open without small business set-asides. A for-profit firm headquartered in Alexandria, Virginia, with over 40 years of federal contracting history, GRA Inc. delivers economic analysis, benefit-cost modeling, forecasting, cost allocation studies, and policy advisory services predominantly to the Federal Aviation Administration.

GRA Inc.'s customer concentration is extreme. The FAA accounts for 98 awards valued at $2.1 billion in combined potential value, representing 83% of the top-customer concentration and 96% of total potential value across all 198 awards in the source data. Within the FAA, the Headquarters organization anchors the largest dollar share, while the Southwestern Region and the Aeronautical Center represent secondary engagement points with smaller task order values. The Department of Homeland Security's Transportation Security Administration, GSA Federal Acquisition Service, and the Department of Justice's Antitrust Division together account for less than 5% of total dollars. The Antitrust Division engagement is specialized: GRA Inc. has held definitive contracts for expert witness services valued at $100,311 and $199,424, reflecting its recognized technical expertise in aviation economics litigation support.

GRA Inc. operates primarily through two core IDIQs with the FAA. The $8.75 million single-award indefinite delivery contract (DTFAWA15D00046) awarded November 30, 2023, and running through November 2026, has generated ten task orders valued collectively at $4.7 million through July 2025. The contract vehicle funds economic consulting services for regulatory analysis and policy support across aviation forecasting, unmanned aircraft systems policies, airport revenue management, and air traffic services cost allocation. Recent representative delivery orders under this IDIQ include a $1.9 million task order for project planning and recurring progress reporting (August 2024), a $548.7 million update to the cost allocation and revenue estimation model (May 2024), a $412.5 thousand benefit-cost model support for surface systems and lighting analysis at U.S. airports (September 2024), a $303.5 thousand research and development support task for the U.S. airport slot allocation framework (May 2024), and a $96.9 thousand commercial space launch forecast delivery (August 2025). GRA Inc. also holds an older indefinite delivery contract (DTFAWA10D00046) with 64 task orders valued at $11.6 million, a GSA Federal Supply Schedule seat (GS10F0214J) generating 14 task orders at $8.8 million, and an older FAA IDIQ (DTFAAC08D00010) with 12 task orders valued at $107.2 million. A single Total Small Business set-aside BPA call through GSA's Electronic FAA Accelerated and Simplified Tasks (eFAST) vehicle, awarded January 6, 2023, carries a $32.7 million ceiling for AJR-G performance reporting tool development and international performance reporting capabilities, running through January 2028.

GRA Inc.'s award activity has remained relatively flat over the past five years—6 awards in 2022, 8 in 2023, 9 in 2024, then declining to 2 each in 2025 and 2026 to date. The portfolio shows 6 awards with ultimate completion dates in the next twenty-four months, carrying combined potential value of $43.6 million, representing moderate recompete exposure concentrated in the FAA Southwestern Region and Headquarters. Combined dollars obligated across all 198 awards total $87.6 million, or 4% of combined potential value, indicating the portfolio consists primarily of ceiling-value awards with execution-phase utilization still to unfold. Primary NAICS concentration sits with Administrative Management and General Management Consulting Services (145 awards), and primary PSC concentration is R&D—Defense Other: Services, Management/Support (87 awards), followed by Special Studies/Analysis—Data and Policy Review/Development support work. GRA Inc. has no subcontract footprint in the source data, operating exclusively as a prime contractor.

GRA provides economic research and consulting services to the transporation industry including aviation policy and planning, aviation safety, cost-benefit analysis, financial services, economic impact studies and privatization.
