About the company

Written by GovTribe AI ·

Weston Solutions Inc., a Pennsylvania-based subsidiary of Weston Solutions Holdings Inc., is a large environmental remediation, infrastructure repair, and emergency response contractor competing on multiple federal indefinite-delivery vehicles without set-aside restrictions. The firm operates as a prime contractor on 99% of its award footprint, holding substantial IDIQ ceilings across the Environmental Protection Agency, U.S. Army Corps of Engineers, and Department of Defense for Superfund site assessment, petroleum systems repair, environmental remediation, and emergency response services nationwide and globally.

Weston's customer concentration is split between environmental and energy-focused agencies. The top tier includes the Army Corps of Engineers Omaha District (109 awards, $12.95 billion combined potential value), Defense Logistics Agency Energy (109 awards, $4.37 billion), and Air Force Materiel Command (30 awards, $3.16 billion potential value). By award count, the Environmental Protection Agency dominates with 471 awards across six regional START (Superfund Technical Assessment Response Team) vehicles, collectively worth $1.8 billion in potential value. EPA Region 9 alone represents 206 awards valued at $807.1 million. This customer concentration reflects Weston's established position as a prime environmental response contractor across federal agencies, with particular depth in EPA regional remediation work and DoD fuel infrastructure operations.

Weston's recent capability work spans environmental remediation, site assessment, emergency response, infrastructure repair, and facility renovation. Representative delivery orders include a $99.4 million cost-plus-fixed-fee order from the Army Corps of Engineers for environmental remediation at East Helena, Montana (Operable Unit 2, through March 2031); a $87.9 million design-build order from Naval Facilities Engineering Command for petroleum tank inspection and repair at Diego Garcia (through March 2030); an $87.1 million firm fixed-price order for fueling system repair and modification at Fort Cavazos, Texas (through September 2026); a $41.9 million remedial action delivery order at Camp Croft, South Carolina (through September 2028); and multiple EPA START V delivery orders across regions for Superfund site assessments and emergency response, including a $50 million 2025 California wildfire emergency response order. The firm also holds nine regional START IDIQ vehicles (Regions 1, 2, 3, 6, 9, and 10) ranging from $59.7 million to $152 million in ceiling value.

Vehicle positions are extensive. Weston holds or participates on the following named parent IDIQs: EPA Region 9 START contract ($152.1 million, awarded September 2026); EPA Region 1 START contract ($62.4 million, through December 2029); EPA Region 2 START VI ($87.1 million, through December 2029); EPA Region 3 START VII ($67.3 million, through March 2031); EPA Region 6 START V ($59.7 million, through August 2028); an $2.5 billion DoD-wide petroleum, oil, and lubricant systems construction and repair vehicle (AFCEC Fuels MATOC, through March 2035); a $2 billion Energy Resilience and Conservation Investment Program MATOC (Army Corps Omaha, through April 2036); a $500 million Multiple Award Environmental Services vehicle with Army Corps Baltimore (through August 2030); a $245 million Heavy Metals Remediation MATOC with Army Corps Louisville (through August 2030); a $150 million Unrestricted Fuels MATOC (Army Corps Omaha, through October 2029); a $18 million FBI Global Multiple Award Construction Contract (Region 3, through November 2031); and a $999.999 billion government-wide OASIS+ Unrestricted MAC (through December 2029). Across EPA regions and the Army Corps, Weston places 130–330 task orders per major vehicle annually, with top vehicle activity concentrated on architect-engineering and environmental remediation services.

Activity has grown consistently. Awards per year rose from 48 in 2022 to 65 in 2025, with 36 awards in 2026 year-to-date (through late September). Recompete exposure includes 111 awards with ultimate completion in the next twenty-four months, carrying combined potential value of $556.8 million. Recent new IDIQs awarded demonstrate continued access to prime vehicles: EPA Region 9 START contract (September 2026, $152 million); EPA Region 3 START VII (November 2025, $67.3 million); FBI Global Construction (May 2026, $18 million); Army Corps Heavy Metals MATOC (August 2025, $245 million); and Army Corps Environmental Services MATOC (August 2025, $500 million).

SCI-reportable service-contract invoicing totaled $110.7 million from FY2022 through FY2025, with FY2025 showing $40.2 million across 128 FTEs—a 26% increase in FTE count and 26% increase in invoicing versus FY2024. Median government-paid hourly rates run around $123.53/hr, with 10th percentile rates near $91/hr and 90th percentile rates reaching $338/hr, reflecting a portfolio spanning field technicians through senior engineers and program managers. Across SCI-reportable prime contracts, subcontractors performed approximately 2% of contractor hours, with 54 named subcontractors engaged. This low subcontracting share indicates Weston self-performs the majority of labor on SCI-reportable work.

Teaming is limited: Weston operates primarily as a large prime contractor and rarely subcontracts to larger firms. The 21 sub-award records in the source represent less than 1% of total awards, with named primes including AECOM Technical Services, KBR Services LLC, Weeks Marine Inc., and The Dutra Group on infrastructure and environmental remediation projects. Named subcontractors to Weston include specialized providers such as Beacon Environmental Services Inc. (laboratory analysis), Eurofins Environmental Testing (analytical services), Als Environmental (laboratory services), Discovery Drilling Inc. (Alaska-based drilling, veteran-owned small business), Idexx Laboratories Inc. (water quality testing), and multiple small disadvantaged and women-owned businesses, suggesting alignment with federal socioeconomic contracting goals while maintaining operational control of core delivery.

Corporate structure includes seven subsidiaries: Weston Solutions of Michigan Inc., Weston-Cape JV LLC, Weston - ER Federal Services LLC, Weston - CDM Smith JV LLC, Weston-EA JV, Weston International Holdings Inc., and Weston-Eoti LLC. Joint ventures with CDM Smith and other partners enable access to specialized expertise while leveraging the parent entity's federal contracting platform and relationship continuity.

GSA Schedule presence provides labor-category flexibility: Weston maintains 52 active labor categories ranging from $49.54/hr (CAD Operator, high school education) to $187.85/hr (General Engineer SR, bachelor's degree, ten years' experience), with no security-cleared positions offered. This broad labor spectrum supports task order delivery across environmental, engineering, project management, quality assurance, and facility maintenance disciplines, enabling agencies to staff projects with appropriate skill levels without requiring additional competitive procurements.
