About the company
Tallgrass Archaeology LLC, a woman-owned small business based on limited data, operates exclusively as a subcontractor delivering historic and cultural preservation research and development services to federal agencies, with no prime contract awards in the current source record. The vendor holds Woman Owned Small Business and Woman Owned Business designations and is certified as a DOT Disadvantaged Business Enterprise.
Tallgrass Archaeology's federal footprint is nascent and narrow. The vendor has recorded three awards totaling $148 thousand across a two-year window (two awards in 2024, one in 2025), all of them subcontracts. Two sub-awards flow from Booz Allen Hamilton under an Indefinite Delivery Contract (693KA922D00009) for the Department of Transportation Federal Aviation Administration, comprising historic and cultural preservation research in support of Air Traffic Control Tower replacement projects at Gillette-Campbell County Airport (GFK) and El Paso International Airport (ELP). One additional federal grant sub-award, dated October 2025, is categorized as technical assistance but carries no grantor-agency detail in the source. The source categorizes Tallgrass Archaeology's work under Engineering Services and Environmental Consulting Services NAICS codes.
Service Contract Inventory data captures one record in FY2025, a subcontract assignment valued above the $150,000 SCI reporting threshold, with 0.2 FTEs delivered. SCI is a partial view excluding goods, non-federal revenue, and contracts below the threshold; the $148 thousand combined obligation figure and the 0.2 FTE trajectory reflect only the awards present in this source snapshot and do not represent the vendor's full federal services activity or total enterprise revenue. The vendor has not appeared on any government-wide vehicles (GWACs, agency-wide IDIQs, or BPAs) in the current award record and operates entirely as a named subcontractor to larger primes, currently limited to Booz Allen Hamilton work.
