SES Construction And Fuel Services LLC

SES Construction And Fuel Services LLC, a wholly owned subsidiary of Bristol Bay Construction Holdings LLC, is an Alaskan Native Corporation-owned, minority-owned small disadvantaged business headquartered in Knoxville, Tennessee, that operates as a prime contractor (100% of recent awards) delivering design-build and integrated facility construction, renovation, and infrastructure modernization services to the Department of Defense, the Department of the Air Force, and the U.S. Army Corps of Engineers. The vendor competes across both full-and-open and total-small-business-set-aside vehicles, with recent activity showing split set-aside posture — roughly half the sampled recent awards carry total small business designations, while the balance compete without set-aside restriction.

SES Construction's capability portfolio centers on mechanical systems replacement, HVAC upgrades, roof repairs and replacement, building envelope restoration, elevator replacement, public address system installation, electrical infrastructure modernization, and design-build new construction at military medical facilities and air bases. Representative recent work includes a $18.1 million definitive contract with the U.S. Army Corps of Engineers Sacramento District (procuring on behalf of the Department of the Air Force) to design and construct a one-story egress facility for depot-level repairs for the T-7A Advanced Pilot Trainer Campus at Hill Air Force Base, Utah, with completion targeted for October 2028; a $14.7 million delivery order under the Army MEDCOM Design Build MATOC 2 to replace Chiller 5 and Boilers 1, 2, and 3 at the Womack Central Energy Plant at Fort Liberty, North Carolina, closing September 2027; and a $24 million delivery order from the Defense Health Agency for design-build repair of the Naval Base Ventura County Port Hueneme Medical Center clinic building exterior, including column restoration, window and door replacement, and restroom renovations, due April 2026.

Customer concentration aligns tightly with Army Corps of Engineers district offices and the Department of Defense medical and facilities portfolio. The top five customers by combined potential value account for 75% of SCI-reported dollars: the Army Corps of Engineers (undifferentiated) carries $1.19 billion combined potential value across six awards; the Army Corps of Engineers Engineering District Louisville, $290.1 million across six awards; the Department of Defense, $287 million across seventeen awards; the Department of the Air Force Air Mobility Command, $267.8 million across seven awards; and the Army Corps of Engineers Engineering District Little Rock, $240.7 million across forty-seven awards. When ranked by award count, the concentration is distributed across multiple Corps district offices — Nashville (51 awards, $23.2 million), Fort Worth (47 awards, $32.8 million), Little Rock (47 awards, $240.7 million), and Savannah (44 awards, $67.8 million) lead volume. The Little Rock district dominates the dollars-to-volume ratio, signaling anchoring work under large indefinite-delivery vehicles at that location.

SES Construction holds positions on five principal parent indefinite-delivery vehicles driving task-order volume: Indefinite Delivery Contract W912P511D0004 (51 task orders, $11.3 million combined potential value); W9126G11D0066 (46 task orders, $12.8 million); N6945014D0013 (34 task orders, $4 million); W912DR14D0017 (28 task orders, $5.9 million); and W912HN13D0023 (18 task orders, $12.7 million). These vehicles are Army Corps and DoD design-build and medical sustainment contracts. The vendor also holds the Little Rock Medical Sustainment Restoration and Modernization Mission ($900 million multiple-award IDIQ), the Army MEDCOM Design Build MATOC 2 ($240 million multiple-award IDIQ), and the Little Rock Air Force Base MACC 2021–2028 ($150 million multiple-award IDIQ).

Activity has remained steady at five to twelve awards per year over the past five years, though the sample shows only one award in 2026 to date. Nine awards with combined potential value of $94.4 million reach ultimate completion inside the next twenty-four months, presenting recompete exposure across mechanical systems replacement, roofing, and facility infrastructure modernization work at military medical and operational bases. The vendor's recent award footprint aggregates to $3.03 billion combined potential value across 369 prime awards since 2001, with $585.8 million obligated (19% of potential).

SCI-reported federal service-contract invoicing totaled $10.2 million across fiscal years 2022 through 2025, with peak invoicing of $6 million in FY2022 declining to $482 thousand by FY2025. The SCI dataset reflects roughly 1.5 FTEs in FY2022 through 1.0 FTE in FY2025 on prime contracts captured in the inventory (a significant undercount of actual federal delivery, as SCI excludes goods, construction projects, and sub-receipted work). Across SCI-reportable prime contracts, government-paid hourly rates ran median $347.52 per hour, spanning a 10th percentile of $282.31 per hour and a 90th percentile of $585.84 per hour. Subcontractor engagement on SCI prime records averaged 39% of total contractor hours, with 28 named subcontractors reported across the inventory — signaling material sub-reliance on SCI service work, though the bulk of SES Construction's federal activity is project-based construction delivery where the prime-versus-sub split does not apply.

Bristol Bay Construction Holdings LLC, the parent entity, holds multiple significant indefinite-delivery contracts valued in the hundreds of millions to over one billion dollars across the Department of Defense, Defense Health Agency, Army Corps of Engineers, and Department of the Interior, positioning SES Construction as a delivery arm within a larger Alaskan Native Corporation federal contracting platform.
