About the company
SES Civil And Environmental LLC Company Headquarters Division, an Alaskan Native Corporation-owned, SBA 8(a) certified small disadvantaged business headquartered in Knoxville, Tennessee, operates as a prime contractor delivering environmental remediation, construction, and infrastructure services to the federal government across multiple defense and civilian agencies. The vendor competes predominantly in full-and-open task order awards issued under large indefinite delivery vehicles and sole source 8(a) set-asides, with 100% of awards captured in the source as prime contracts.
SES Civil And Environmental's capability portfolio centers on AFFF (aqueous film-forming foam) mitigation and disposal, environmental remediation and hazardous waste management, bank and shoreline stabilization, access control point design-build, facility renovation and repair, and specialized infrastructure construction at military installations. Representative work includes a $27.7 million 8(a) Sole Source contract from the Air Force Civil Engineer Center for PFAS mitigation and monitoring at former Reese Air Force Base in Lubbock, Texas (completion November 2026); a $27.5 million Total Small Business Definitive Contract from the Army Corps of Engineers Kansas City District for Access Control Point modifications supporting the National Geospatial Intelligence Agency's West Facilities Modernization program in St. Louis, Missouri (completion February 2026); and a $10.4 million Total Small Business Definitive Contract from the Army for installation of a new toe drain at John H. Kerr Reservoir in Boydton, Virginia (completion November 2026).
The vendor's customer concentration is heavily anchored by the Army Corps of Engineers across multiple districts, which accounts for the largest share of both award count and potential value. The top five funding entities by potential value—the Army Corps of Engineers' Engineering Support Center Huntsville, Engineering District Baltimore, Engineering District Savannah, Engineering District Mobile, and the Air Force Civil Engineer Center—represent 84% of combined potential value. Within award count, the top five (Navy Naval Facilities Engineering Command, Army Corps of Engineers at the agency level, Savannah District, Jacksonville District, and Air Force Civil Engineer Center) cover 46% of awards, with Navy NAVFAC at 36 awards valued at $20.4 million and Savannah District at 16 awards valued at $93.4 million. The divergence reflects a handful of mega-vehicles anchoring most dollars while Navy and Jacksonville District issue higher volumes of smaller task orders.
SES Civil And Environmental holds four large indefinite delivery vehicles with ceiling values representing the bulk of its federal contract footprint. The $800 million Aqueous Film Forming Foam Support Services MATOC with the Army Corps of Engineers Engineering Support Center Huntsville (ultimate completion February 2029) establishes the vendor as a primary AFFF disposal contractor across 24 Department of Defense installations. The $499 million Design-Build and Design-Bid-Build Construction Services multiple-award contract with the Army Corps of Engineers Baltimore District (completion September 2028) supports North Atlantic Division infrastructure projects. The $95 million Access Control Point Design Build II multiple-award Competitive 8(a) vehicle with Engineering Support Center Huntsville (completion August 2026) covers design-build security checkpoint construction across CONUS, Alaska, Hawaii, and outlying areas. The $49 million 8(a) Sole Source Design-Build and General Construction single-award vehicle with the Army Corps of Engineers Savannah District (completion August 2024) covers Fort Bragg, North Carolina facilities work. Under these vehicles, SES Civil And Environmental typically receives firm fixed-price delivery orders ranging from $20,000 minimum guarantees to $8.3 million task orders for specific environmental, construction, or infrastructure scopes.
Activity has declined since 2022, when the vendor recorded 26 awards. The past five years show 26 awards in 2022, 23 in 2023, nine in 2024, eight in 2025, and one in 2026 (as of March). The 203 total awards in the source data carry combined potential value of $1.94 billion, with only $332.8 million (17%) obligated to date. Fifteen awards (combined potential value $53.1 million) reach ultimate completion within the next twenty-four months, representing recompete risk for the vendor and recompete opportunity for competitors.
The vendor's parent is Bristol Bay Construction Holdings LLC, an Alaskan Native Corporation-owned firm also designated as a minority-owned, self-certified small disadvantaged business. SES Civil And Environmental operates as a subsidiary division structure, with Company Headquarters Division (the source entity) and a Branch Division referenced across multiple awards, typically for performance location or administrative designation rather than operational separation. The corporate structure supports the vendor's multi-site execution across military installations nationwide, with awards performed in Florida, Georgia, Tennessee, North Carolina, Texas, Missouri, Colorado, and other locations.
Category concentration reflects specialization: Remediation Services NAICS accounts for 72 awards, Commercial and Institutional Building Construction for 52 awards, and Other Heavy and Civil Engineering Construction for 21 awards. PSC codes show similar focus—70 awards under Other Environmental Services, 44 under Construction Of Miscellaneous Buildings, and 20 under Maintenance Of Recreation Facilities. This depth in environmental and facility work at military installations positions SES Civil And Environmental as an established preferred contractor for Army Corps of Engineers and Navy NAVFAC task order issuance, though award volume has contracted in recent years.
