About this vehicle
The Department of the Army Corps of Engineers Engineering Support Center Huntsville awarded this unrestricted multiple-award Master IDIQ on August 15, 2022, to procure international remediation and environmental services at overseas military installations, with ordering authority extending to February 15, 2028—approximately 18 months of remaining opportunity.
The vehicle targets military munitions response, aqueous film-forming foam (AFFF) removal and replacement, environmental compliance and remediation, munitions and explosives of concern (MEC) and material potentially presenting an explosive hazard (MPPEH) clearance, and chemical and biological warfare material remediation at locations outside the continental United States, including Afghanistan, Iraq, Japan, Jordan, Kuwait, Lebanon, Poland, South Korea, and Ukraine. Task orders executed to date concentrate heavily on Japan (Okinawa fuel farms, Sagami General Depot, Kubasaki High School), Kwajalein, and Europe, with work priced on a firm-fixed-price or cost-plus-fixed-fee basis.
Five prime contractors hold awards across 16 task orders totaling $115.2 million in combined potential value, with $64.7 million obligated to date. Competition is heavily concentrated: Tetra TECH EC, Inc. and Relyant Global LLC each hold $57.6 million in potential value, with Tetra TECH taking 11 orders and Relyant holding 2. The remaining three primes—AECOM Technical Services, Inc., Global Environmental & Munition Services LLC, and Acuity-Janus Global, LLC—each hold minimal value ($3 thousand each). Ordering momentum has declined: 5 orders in 2022, 6 in 2023, 3 in 2024, and 2 in 2025. The most recent award, issued September 27, 2025, was a Kwajalein AFFF task order with an $796 thousand ceiling. Task-order ceilings range from $796 thousand to $57.6 million, with typical durations of two to five years. The vehicle operates under no set-aside; all 16 orders are unrestricted.
