Arcadis U.s., Inc.

Arcadis U.S., Inc. and its subsidiaries, a foreign-owned design and consultancy firm headquartered in Highlands Ranch, Colorado, deliver environmental remediation, PFAS investigation and treatment, hazardous waste management, architectural and engineering design, infrastructure development, and technical consulting services to federal agencies as a prime contractor on 97% of recent awards, with a $10.86 billion combined potential value across 1,101 prime contracts and indefinite-delivery vehicles. The firm competes exclusively in full-and-open federal procurement without small-business set-asides.

Arcadis U.S., Inc. operates as a subsidiary of Arcadis North America and maintains three named joint-venture subsidiaries: Arcadis-Bergmann Lakes & Rivers JV, Versar-Arcadis A Joint Venture, and Arcadis EXP Federal NY JV. The vendor's capability portfolio centers on environmental site assessments, remedial design and construction phase services, groundwater monitoring and remediation under CERCLA and RCRA, PFAS remediation and source removal, military munitions response, environmental compliance planning, infrastructure and water treatment design, vibration monitoring during construction, and specialized research and development under the Strategic Environmental Research and Development Program (SERDP) and Environmental Security Technology Certification Program (ESTCP). Concrete examples include a $58.1 million firm-fixed-price delivery order from the International Boundary and Water Commission for design and construction of the South Bay International Wastewater Treatment Plant rehabilitation and expansion in San Diego, California; an $8.455 million cost-plus-fixed-fee delivery order from the Air Force Civil Engineer Center for interim removal action and remedial planning for PFAS remediation at the former Wursmith Air Force Base; an $8.113 million delivery order from the Army Corps of Engineers for RDX groundwater remediation at Fort Jackson, South Carolina under the $1.136 billion SEER Chemical, Environmental, and Munitions Contract; and a $13.4 million delivery order from the Army Corps of Engineers Mobile District for design services for the Eastern Jackson County Consolidated Water Reclamation Facility in Mississippi.

Customer concentration is dominated by military and civil-works agencies. The top five funding agencies by award count—the Department of Homeland Security U.S. Coast Guard (211 awards, $247.4 million), the Army Corps of Engineers (82 awards, $106.4 million), the Army Corps of Engineers Engineering District New Orleans (65 awards, $43.6 million), the Army Corps of Engineers Engineering District Nashville (63 awards, $7.9 million), and the Air Force (63 awards)—account for 43% of recent awards. By potential value, concentration shifts to larger district-level IDIQs: the Army Corps of Engineers Baltimore District ($929.2 million across 34 awards), the Army Corps of Engineers Mobile District ($910.4 million across 24 awards), the Army Corps of Engineers Kansas City District ($847.2 million across 13 awards), the Army Installation Management Command Headquarters ($797.4 million across 25 awards), and Naval Facilities Engineering Command ($525.6 million across 11 awards) account for 37% of combined potential value. The Coast Guard dominates by award frequency, while the Baltimore, Mobile, and Kansas City districts anchor the largest single-vehicle concentrations.

Arcadis holds position on multiple high-value indefinite-delivery vehicles. The Coast Guard's Nationwide Environmental Engineering Services IDIQ (contract DTCG8302D3CL373, $1.63 billion) carries 93 task orders and represents the single largest vehicle by potential value, covering environmental compliance planning, stormwater management design, RCRA groundwater monitoring, CERCLA Superfund activities, and spill prevention planning across Coast Guard installations. The firm holds multiple Army Corps of Engineers environmental remediation and architect-engineer MATOCs and IDIQs: the $1.136 billion SEER Chemical, Environmental, and Munitions Contract; the $800 million Aqueous Film Forming Foam Master Omnibus contract for PFAS removal from Department of Defense firefighting foam systems; the $464 million Environmental Remediation MAIDIQ; a $249 million Environmental Architect-Engineer Services MATOC with the Omaha District; a $225 million Hazardous, Toxic, and Radioactive Waste Services contract with the Kansas City District; and a $200 million A/E services contract with the Baltimore District. The firm also sits on the General Services Administration's OASIS+ Unrestricted multiple-award contract (awarded July 2026, eight-year term through December 2034) and holds a $100 million Architect-Engineering Environmental Services contract with the Air Force Civil Engineer Center (A-E ES 2023, worldwide scope, March 2025 through March 2035).

Activity has grown from 23 awards in 2022 to a peak of 43 in 2024, settling at 31 in 2025 and 17 through early October 2026 (a partial year). Forty-five awards with ultimate completion dates in the next twenty-four months carry combined potential value of $85.6 million and represent recompete exposure, principally on Coast Guard Nationwide Environmental Engineering task orders and multiple smaller Army Corps of Engineers district vehicles.

In its subcontractor role, Arcadis delivers environmental consulting, research, and program management support to larger defense and infrastructure primes. Named sub-awards include work under Pantexas Deterrence for Pantex Plant management and operations, HDR Architecture for value engineering and facility security upgrades at diplomatic compounds, General Dynamics Information Technology for cybersecurity branch support and water contamination response, Deloitte Consulting for FEMA Risk Management Directorate program management, and academic institutions including the University of Texas at Austin, the University of Arizona, and the Trustees of the Colorado School of Mines for ESTCP and SERDP research projects focused on PFAS leaching, vadose zone mass discharge characterization, and modified-clay jet-grouting isolation techniques.

Service Contract Inventory data shows SCI-reportable invoiced revenue of $26.6 million across FY2022–FY2025 (prime contracts above the $150,000 reporting threshold). FY2025 invoicing of $11.6 million across 16.8 FTEs represents growth from FY2024's $4.8 million across 8.0 FTEs. Government-paid hourly rates on federal services contracts captured in SCI ranged from a 10th percentile of $69.77/hr to a median of $272.11/hr and a 90th percentile of $552.74/hr, reflecting a mix of technical and specialized labor. Across SCI-reportable prime contracts, the vendor self-performed substantially all labor with minimal subcontractor engagement (0% average sub-hours share).

Arcadis has established primary relationships with Kennedy/Jenks Consultants for project and construction management, Pace Analytical Services for laboratory analysis and environmental testing, and various small and disadvantaged business subcontractors including Civil Design & Construction (woman-owned), Eustis Engineering (geotechnical services), and Hana Engineers & Consultants (8(a) small disadvantaged business) to supplement in-house delivery on environmental remediation, infrastructure design, and construction support projects. The firm competes entirely in unrestricted federal procurements, with NAICS concentration in Engineering Services (715 awards) and Environmental Consulting Services (63 awards) and PSC concentration in Architect and Engineering general design (350 awards) and landscaping and interior layout (345 awards).
