WSP USA Environment & Infrastructure Inc.

WSP USA Environment & Infrastructure Inc., a foreign-owned subsidiary of the global AMEC PLC, delivers environmental engineering, infrastructure support, and facilities management services to federal agencies as a prime contractor across an extensive portfolio spanning 2,886 prime awards worth a combined $45.1 billion in potential value. The vendor competes as a large business without small business set-asides, maintaining a dominant presence in architect-engineering services, environmental remediation, and facility operations across civilian and defense agencies.

The company's customer concentration is heavily weighted toward the Air Force (roughly 38% of total award count and 36% of potential value), with the Air Force Civil Engineer Center anchoring $10.4 billion in task-order authority, followed by Defense Logistics Agency Energy ($3.9 billion), the Environmental Protection Agency ($750.6 million across administrative and air-radiation divisions), the U.S. Army Corps of Engineers ($586 million), and the U.S. Coast Guard ($234 million). Recent award activity has declined sharply—from 124 awards in 2022 to only ten as of mid-2026—signaling either a shift in federal procurement patterns or the vendor's focus on higher-value task orders rather than volume. Within the next twenty-four months, sixty-four awards with combined potential value of $233.4 million reach ultimate completion, presenting significant recompete exposure.

Capability framing derives from award detail: WSP delivers site assessments and environmental investigations (including Phase I/II ESAs, CERCLA remedial investigations and feasibility studies, and PFAS assessments); petroleum, oil, and lubricant tank cleaning, inspection, repair, and modernization at global Defense Fuel Support Points and military installations; architect-engineer design services for facility upgrades, HVAC repairs, fire suppression systems, and infrastructure restoration; air quality monitoring and operations support under EPA's Clean Air Status and Trends Network (CASTNET) program; hazard mitigation technical assistance and environmental compliance support under FEMA's Hazard Mitigation Technical Assistance Program; and facility operations, maintenance, and transition management at civilian research and administrative centers. A representative sampling: a $35.5 million delivery order for tank cleaning, inspection, and repair at Naval Station Rota, Spain (September 2025); a $21.9 million delivery order for tank cleaning and in-service inspections at Defense Fuel Support Point Tsurumi, Japan (September 2024); a $13.53 million FEMA order for hazard mitigation grant evaluation across the Pacific region (November 2024); a $10.56 million CERCLA remedial investigation and feasibility study at Cold Regions Research and Engineering Laboratory, Hanover, New Hampshire (September 2024); a $4.28 million cost-plus-fixed-fee delivery order for PFAS response and monitoring at former Pease Air Force Base, Portsmouth, New Hampshire (September 2025); and a $163 million single-award EPA Blanket Purchase Agreement for comprehensive infrastructure support services through February 2028.

WSP holds three mega-vehicles: a $2.5 billion Department of Defense AFCEC Fuels MATOC for worldwide petroleum systems construction and repair (awarded March 2025, through March 2035); a $249 million U.S. Army Corps of Engineers Environmental Quality Program contract (awarded April 2025, through April 2030); and a $100 million Air Force Civil Engineer Center architect-engineering environmental services contract (awarded March 2025, through March 2035). The vendor also holds a $163 million single-award EPA Blanket Purchase Agreement and multiple smaller IDIQs with the Army Corps of Engineers (a $25 million architect-engineer MATOC through July 2029 and a $5 million geotechnical services BPA through September 2028) and FEMA (a $93.3 million Hazard Mitigation Technical Assistance Program contract through September 2027). Task-order placement is concentrated on five parent vehicles: Indefinite Delivery Contract FA890308D8766 (249 task orders, $279.3 million), the GSA Multiple Award Schedule (201 task orders, $335.7 million), Indefinite Delivery Contract EPD15041 (177 task orders, $25.1 million), Indefinite Delivery Contract FA890304D8669 (175 task orders, $178.4 million), and Indefinite Delivery Contract F4162403D8591 (147 task orders, $10.2 million).

SCI-reported service-contract invoicing totaled $49.9 million across FY2022–FY2024, with FY2022 at $20.6 million (49.9 FTEs), FY2023 at $19.2 million (54.1 FTEs), and FY2024 at $10.1 million (52.9 FTEs). Median government-paid hourly rates on prime contracts ran around $157/hour, with rates ranging from $54.76/hour at the tenth percentile to $621.65/hour at the ninety-first percentile. On SCI-reportable prime contracts, subcontractors accounted for an average of 14% of total contractor hours, with thirty-nine named subcontractors reported across the portfolio. GSA Schedule labor rates span sixty-five categories from $34.17/hour (CAD drafter, high school education) through $262.10/hour (executive management consultant, bachelor's degree with fifteen years' experience); no security-cleared positions are offered.

WSP operates as a prime on 99% of its awards and subcontracts to other primes on only 1% (twenty-four sub-awards), indicating the vendor builds its own delivery teams for most engagements. Named subcontractors include CDM Federal Programs Corporation (environmental and engineering consulting on FEMA hazard mitigation work), EA Engineering Science and Technology Inc. (design and engineering services on remediation projects), Gilbane Building Co (logistical and move support), and SGS North America Inc. (laboratory analysis services). The corporate structure identifies A M E C PLC as the parent company.
