About Weston Solutions Inc.

Written by GovTribe AI ·

Weston Solutions Inc., a subsidiary of Weston Solutions Holdings, Inc., delivers environmental remediation, site assessment, infrastructure repair, and emergency response services to the federal government as a prime contractor (99% of awards) across EPA, Army Corps of Engineers, Department of Defense, and Air Force accounts. The company operates without SBA set-aside designations, competing full-and-open on over 3,700 prime federal awards worth $46.2 billion in combined potential value.

Weston Solutions' capability portfolio centers on hazardous substance removal, Superfund site technical assessment, petroleum infrastructure construction and repair, and environmental compliance services. Representative work includes a $99.4 million cost-plus-fixed-fee delivery order from Army Corps ENDIST Omaha (March 2026) for environmental remediation at East Helena, Montana's Operable Unit 2, extending through March 2031; a $87.9 million firm fixed-price NAVFAC EXWC order (September 2025) for cleaning, inspection, and repair of six petroleum, oil, and lubricant tanks at Defense Fuel Support Point Diego Garcia, through March 2030; and a $50 million Superfund Technical Assessment Response Team (START) V delivery order from EPA Region 9 (January 2025) for 2025 California wildfire emergency response with partner subcontractors including South Coast Air Quality Management District and General Pacific Inc. Across SCI-reportable federal service contracts, Weston invoiced $70.6 million in FY2022–FY2024, with FY2024 showing $31.9 million across 99.9 FTEs and a median government-paid hourly rate of $123.53/hr, ranging from $89.96/hr (10th percentile) to $380.93/hr (90th percentile).

Customer concentration is heavily weighted to Army Corps of Engineers and Defense Logistics Agency dollars. The top five customers by potential value account for 54% of combined value: Army Corps ENDIST Omaha leads with 108 awards ($12.94 billion), followed by Defense Logistics Agency Energy (112 awards, $4.49 billion), Air Force Civil Engineer Center (30 awards, $3.16 billion), Army Corps ENDIST Huntsville (28 awards, $2.94 billion), and Army Corps ENDIST Baltimore (149 awards, $1.6 billion). By award count, the Army, EPA, and Air Force dominate; EPA Region 9 alone placed 199 awards ($414.5 million). Weston competes across 107 distinct agencies, reflecting a highly diversified customer base.

Weston holds extensive parent vehicle capacity across both environmental and infrastructure domains. Key IDIQ vehicles include a $2.5 billion DoD-wide petroleum, oil, and lubricant systems construction and repair MATOC (March 2025, extending through March 2035); a $668.9 million temporary power generation delivery order under the Puerto Rico Power System Stabilization vehicle (February 2023, extended through March 2026); a $500 million worldwide DoD POL facilities architect-engineering IDIQ (April 2023, through March 2028); a $245 million Army Corps Louisville nationwide heavy metals remediation MATOC (August 2025, through August 2030); and a $500 million Multiple Award Environmental Services MATOC with Army Corps Baltimore (August 2025, through August 2030). Weston also holds a $999.9 billion OASIS+ Unrestricted government-wide MAC (December 2024, through December 2029), a $87.1 million EPA Region 2 START VI single-award IDIQ (December 2024, through December 2029), and a $67.3 million EPA Region 3 START VII single-award vehicle (November 2025, through June 2030). The Superfund Technical Assessment Response Team V (START V) family represents a major vehicle network: Weston holds or holds positions on regional START contracts with EPA Regions 1, 2, 3, 6, 9, and 10, collectively representing hundreds of millions in potential value with ultimate completion dates extending through 2028–2030.

Activity has remained steady at 48–65 awards per year over FY2022–2026, with 121 awards (combined potential value $554.2 million) reaching ultimate completion within the next twenty-four months, signaling substantial recompete exposure. Weston primarily builds its own delivery teams — across SCI-reportable prime contracts, subcontractors performed only 2% of total contractor hours, with 24 named subcontractors identified. The vendor engages small disadvantaged businesses, women-owned small businesses, service-disabled veteran-owned firms, and HUBZone providers as subs on major orders; named sub partners include Oasis Aviation Services LLC (WOSB), Fuel TECH Electric LLC (SDB), Ensafe Inc., Pace Analytical Services LLC, Eurofins Environment Testing divisions, ALS Group USA (laboratory testing), and Discovery Drilling Inc. (VOSB in Alaska).

Corporate structure includes six named subsidiaries: Weston Solutions Of Michigan, Inc.; Weston – ER Federal Services, LLC (environmental remediation-focused); Weston – CDM Smith JV, LLC (joint venture positioning); Weston-EA JV (joint venture); Weston International Holdings, Inc.; and Weston-Eoti, LLC (joint venture). Headquarters is in West Chester, Pennsylvania. GSA Schedule MAS labor portfolio spans 52 active categories at $49.54–$187.85/hr, covering CAD operators through senior-level engineers with no security clearance requirements. NAICS concentration leans toward remediation services (1,155 awards), environmental consulting (401 awards), and engineering services (260 awards); PSC codes emphasize architect-and-engineering general work (596 awards), environmental systems protection remediation (245 awards), and emergency response support (242 awards).
