Four Tribes Enterprises, LLC

Four Tribes Enterprises, LLC, a tribally-owned 8(a)-certified small disadvantaged business headquartered in Reno, Nevada (and administratively referenced as Gaithersburg, Maryland in certain award summaries), delivers construction, facilities maintenance, and infrastructure repair services to the Department of Defense and allied federal agencies as a prime contractor across 100% of its recent federal award footprint. The vendor operates as a subsidiary of Sirco Development Holdings, LLC, a parent tribally-owned entity.

Four Tribes Enterprises' federal work centers on concrete, mission-critical infrastructure: HVAC system replacement and repair, building renovation and envelope work, electrical upgrades, chiller replacement, boiler maintenance, fire suppression system repair, and site preparation at military installations. Representative work includes a $10.38 million Competitive 8(a) definitive contract with the General Services Administration to construct the San Ysidro Land Port of Entry FMCSA Bus Inspection Facility in San Diego, California (awarded May 29, 2026, ultimate completion June 15, 2028); a $15.07 million sewer infiltration repair program at Davis-Monthan Air Force Base in Arizona under the Army Corps of Engineers Los Angeles District; and a $12.75 million 8(a) sole-source award for storm damage repairs to the Jewish Chapel (Building 750) at West Point, New York (awarded September 29, 2023, ultimate completion September 30, 2025). The vendor also holds delivery orders for smaller facility maintenance tasks—HVAC controls replacement, water heater installation, fire inspection services—ranging from $17 thousand to $3.7 million at Fort Jackson, Luke Air Force Base, Edwards Air Force Base, Cannon Air Force Base, and Seymour Johnson Air Force Base.

Customer concentration is heavily weighted to Air Force and Army Corps of Engineers facilities. The top five funding agencies account for 73% of recent awards by count, led by Air Force Materiel Command (63 awards, $70.4 million combined potential value), Army Corps of Engineers Engineering District Charleston (45 awards, $79.7 million), Air Combat Command (25 awards, $41.3 million), Air Education and Training Command (23 awards, $36.3 million), and Army Corps of Engineers Engineering District Los Angeles (11 awards, $50.4 million). By potential value share, Charleston District and Materiel Command dominate; however, ACOE Los Angeles and Air Force Space Command carry outsized value-per-award magnitudes, anchoring large definitive contracts for civil works and facility renovation.

Four Tribes Enterprises operates primarily under single-award and multiple-award indefinite delivery contracts. The largest vehicle by task-order volume is Indefinite Delivery Contract FA930119DA009 (Air Force Materiel Command, Edwards Air Force Base HVAC and building systems support), from which 61 task orders totaling $33.2 million have been issued. Other high-volume vehicles include the $49 million Army Corps of Engineers Engineering District Charleston IDIQ for Fort Jackson general construction (32 task orders, $13.1 million to date as of source snapshot), the $25 million Air Education and Training Command SABER vehicle at Luke Air Force Base (22 task orders, $11.4 million), the $9.999 million Air Force Special Operations Command IDIQ for Cannon Air Force Base (10 task orders, $8.4 million), and the Army Corps of Engineers Los Angeles District $2 million POCA vehicle (10 task orders, $3.3 million). These IDIQs enable streamlined task-order issuance and position Four Tribes as a primary facilities maintenance provider across multiple installations.

Activity shows recent deceleration after years of growth. The vendor received 45 awards in 2022, 48 in 2023, 37 in 2024, 16 in 2025, and 2 in 2026 (through May 29). This year-over-year decline—from 48 in 2023 to 37 in 2024 to 16 in 2025—signals either reduced government demand, slower award velocity, or a shift toward fewer, larger contracts. Combined potential value across all 229 awards stands at $490.6 million; $326.2 million (66%) has been obligated. Within the next twenty-four months, six awards with combined potential value of $19.3 million face ultimate completion, creating moderate recompete exposure.

SCI-reportable service contract invoicing is sparse relative to the construction-heavy award portfolio. Four Tribes Enterprises reported $2.4 million in invoiced federal service revenue across FY2022–FY2024: $99 thousand (FY2022), $381 thousand (FY2023), and $1.9 million (FY2024). Workforce on SCI-reportable contracts averaged roughly 0.9–1.4 FTEs per fiscal year. Government-paid hourly rates on SCI contracts ranged widely, with a median of $110.42/hr and a 90th percentile of $1,242.89/hr, reflecting the mix of labor-hour and equipment-intensive facility work. Across SCI-reportable prime contracts, subcontractors performed approximately 28% of total contractor hours, with six named subs identified in the source data—a signal that Four Tribes Enterprises builds delivery teams with subcontractor support on service contracts, though the dollar volume of SCI work is modest compared to the construction contract footprint.

The vendor competes entirely as a prime contractor (100% of awards); it has no sub-award history in the source. Four Tribes Enterprises leverages 8(a) sole-source set-asides for a material portion of its awards, particularly on definitive (fixed-scope) contracts; however, the bulk of task orders under its IDIQ vehicles carry no set-aside designation, reflecting its competitive standing on full-and-open procurement once the parent vehicle is secured. NAICS coding reflects construction focus: 116 awards under Commercial and Institutional Building Construction (236220), 78 under Plumbing, Heating, and Air-Conditioning Contractors (238220), and 11 under Facilities Support Services. Work is performed nationwide at military installations in CONUS and OCONUS, with administrative and customer concentration centered on Air Force and Army facilities in the Southwest, Southeast, and Mid-Atlantic regions. The vendor's ownership structure as a tribally-owned small disadvantaged business certified under 8(a) anchors its federal strategy, enabling both sole-source and competitive set-aside access while supporting agency small business contracting goals.

Four Tribes Enterprises (FTE) is a full-service tribally-owned 8(a) general contractor with construction expertise in many areas to include: renovations, design-build, LEED, sensitive compartmented information facilities (SCIF), laboratories, paving, sewer, stormwater management, demolition, high voltage electric, engineering, mechanical, and many more under 237310 and 236220 NAICS Codes.
