About the company
Resolution Consultants - An Aecom-Ensafe Joint Venture, a strategic partnership between global infrastructure firm AECOM and environmental services specialist EnSafe Inc., operates as a large business prime contractor delivering environmental remediation, PFAS investigation, and facilities support services to the U.S. Navy. The joint venture competes full-and-open on the Department of Defense, winning awards without reliance on small business set-asides.
The joint venture's federal footprint is heavily concentrated with Naval Facilities Engineering Command (NAVFAC), which accounts for 412 of 436 prime awards and $1 billion of the combined $1.02 billion potential value. Resolution Consultants holds the $400 million Comprehensive Long-Term Environmental Actions Navy (CLEAN) single-award indefinite-delivery/indefinite-quantity contract awarded May 2, 2022, through May 1, 2027, and operates as the exclusive environmental remediation contractor under two NAVFAC parent IDIQs — Indefinite Delivery Contract N6247011D8013 (282 task orders, $201.4 million combined potential value) and Indefinite Delivery Contract N6247022D0005 (152 task orders, $222 million combined potential value). Beyond NAVFAC, the vendor has smaller footholds with Department of the Navy Installations Command (8 awards, $5.1 million), Pacific Fleet Forces (6 awards, $8.4 million), Fleet Forces Command Atlantic (4 awards, $1.3 million), and Naval Sea Systems Command (2 awards, $4.7 million).
Concrete capability framing: Resolution Consultants delivers per- and polyfluoroalkyl substances (PFAS) remedial investigations, groundwater sampling and long-term monitoring, unexploded ordnance assessment and removal, land use control inspections, Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) documentation and compliance support, site closure and environmental restoration, and facilities operations and maintenance at Navy and Marine Corps installations nationwide and globally. Representative work includes a $10.12 million Phase 4 remedial investigation for PFAS and other CERCLA constituents at Naval Station Newport Site 24 (awarded July 7, 2022); a $8.815 million delivery order addressing maximum contaminant level promulgation and PFAS remediation across Naval Air Station Whiting Field and related Jacksonville-area facilities (awarded February 22, 2024); a $7.02 million PFAS remedial investigation at Marine Corps Air Station Beaufort with expanded scope in Area of Interest 02 through September 2030 (awarded August 25, 2023); and a $6.721 million delivery order for long-term monitoring, land use control monitoring, radiological monitoring, and PFAS-specific monitoring at former Naval Air Station Brunswick in Maine through July 2030 (awarded April 12, 2023). The vendor frequently names subcontractors including SGS North America Inc. for analytical laboratory services, Cascade Drilling L.P. for sonic drilling, East Coast Geophysics Inc. for utility locating, Katahdin Analytical Services LLC and Eurofins Lancaster Laboratories Environment Testing LLC for laboratory analysis, and Battelle Memorial Institute for specialized lab work.
Activity has grown from 23 awards in 2022 to a peak of 69 in 2023, declining to 25 in 2024 and 31 in 2025; 5 awards appear in 2026 year-to-date as of April 17, 2026. Eighty awards with ultimate completion dates in the next twenty-four months carry combined potential value of $90.4 million, representing meaningful recompete exposure as CLEAN task orders mature and new work is tasked.
The CLEAN vehicle dominates the portfolio. Under CLEAN, individual task orders typically carry ceiling values from $40,000 to over $10 million with performance periods of three to five years, covering the full scope of environmental remediation activities from preliminary assessments through site closure. Task order scope ranges from single-site PFAS investigations (such as the $569,637 background study at Naval Station Mechanicsburg, Pennsylvania, awarded April 17, 2026) to basewide environmental restoration programs (such as the $9.24 million CERCLA and real estate support contract at Naval Station Norfolk, awarded March 15, 2023). The vendor has also received standalone delivery orders outside CLEAN for specialized work — for example, a $6.7 million PFAS support and environmental monitoring contract from Pacific Fleet Forces for former Naval Air Station Brunswick through July 2030.
Primary NAICS framing is 541512 (Engineering Services), with all 436 awards falling under A-E (Architect-Engineer) General categories: 404 awards under PSC code for general A-E work, 29 under landscaping and interior layout and design, and 3 under inspection services. The vendor does not compete under 8(a), HUBZone, SDVOSB, WOSB, or other set-aside programs; each award explicitly carries "No Set-Aside Used," positioning Resolution Consultants as a full-and-open large business competitor.
Corporate structure: Resolution Consultants is a child entity of parent AECOM, a for-profit corporate entity. The joint venture structure combines AECOM's global infrastructure and engineering capabilities with EnSafe's specialized environmental remediation expertise, positioning the partnership to deliver both infrastructure scale and environmental technical depth across Navy facility portfolios. The vendor is based in Los Angeles, California (300 S Grand Ave # 900).
