About the company
Four Tribes Civil Construction LLC, a tribally owned, SBA 8(a) certified small disadvantaged business based in Reno, Nevada, delivers federal construction, renovation, and maintenance services as a prime contractor (100% of recent awards) across Department of Health and Human Services, Air Force, Army Corps of Engineers, and Department of Energy facilities. The vendor operates exclusively under 8(a) sole-source set-asides on recent definitive contracts and indefinite-delivery vehicles, with no subcontract footprint in the current award portfolio. Four Tribes Civil Construction is a Native American-owned limited liability company and subsidiary of Sirco Development Holdings, LLC, a tribally owned parent also based in Reno.
Four Tribes' customer base divides evenly between two anchor agencies. The Department of Health and Human Services National Institutes of Health Construction dominates by award count (4 awards, $29.6 million combined potential value), while the Department of the Air Force Materiel Command Research Laboratory matches the NIH on potential value (2 awards, $29.7 million combined potential value). The Department of the Army Corps of Engineers Engineering District St. Louis contributes one Arlington National Cemetery sculpture rehabilitation award ($6.5 million), and the Department of Energy Western Area Power Administration placed a substation cable and waveguide bridge project ($374 thousand). These four agencies represent 100% of the current award portfolio.
Vehicle position centers on a single $25 million indefinite-delivery contract (ceiling August 13, 2031) awarded by NIH Construction on August 12, 2026, for construction, design-build, renovation, maintenance, alteration, and repair supporting the NIH Rocky Mountain Laboratories Campus in Hamilton, Montana. Four Tribes has placed three task orders totaling $4.6 million against this IDIQ. Recent representative work includes a $22.6 million Air Force Research Laboratory delivery order (awarded January 30, 2025) for H7 facility renovation at CASE in Rome, New York (ultimate completion June 30, 2026); three concurrent NIH Construction delivery orders (awarded August 28–31, 2026) totaling $4.6 million for water system, air handling unit, and site electrical redundancy work at Rocky Mountain Laboratories (ultimate completion August 26–30, 2027); a $7.1 million Air Force Research Laboratory competitive small business award (July 1, 2025) for steam boiler installation at Rome Research Site (completion December 28, 2026); and a $373 thousand Western Area Power Administration 8(a) sole-source definitive contract (September 24, 2026) for substation and maintenance facility cabling in Redding, California (completion February 5, 2027).
Activity trajectory shows acceleration: two awards in 2025 growing to six in 2026, with combined potential value now at $66.2 million and $40.9 million obligated (62% drawdown). Six awards carrying $18.6 million combined potential value reach ultimate completion in the next twenty-four months, creating near-term recompete exposure. Capability concentration aligns with facility modernization and infrastructure work—commercial and institutional building construction (6 awards), power and communication line structures (1 award), and maintenance of industrial buildings (4 awards under PSC codes 4105 and related facilities construction). The vendor holds a named subsidiary, Ftsr JV, LLC, which carries small business joint venture and tribally owned designations but does not appear as a separate prime in this award snapshot.
