USACE Multiple Award Environmental Services 2017 (MAES 2017)

The U.S. Army Corps of Engineers, Baltimore District, awarded a Multiple Award IDIQ for environmental services (MAES 2017) on December 21, 2018, with a shared ceiling of $230 million and an ordering period ending June 19, 2024—the vehicle is no longer accepting new orders.

The ordering period closed two years ago, and task-order activity has slowed sharply in 2025 with only two orders placed year-to-date against a historical pace of 8–9 orders annually. Of the $230 million ceiling, $211.4 million has been distributed across 50 awarded task orders, with $153.9 million obligated (73% of combined potential value). The final task order was placed in August 2025, suggesting residual activity but no new procurement authority.

Task orders address environmental cleanup and quality across military and civil programs within the North Atlantic Division area of responsibility, including incidental work in CONUS, Hawaii, Alaska, and Puerto Rico. Scope covers remedial investigations, feasibility studies, remedial actions, operation and maintenance, long-term monitoring, hazardous-materials abatement, building demolition, and munitions-response remediation. PFAS and ordnance remediation appear as growing focus areas in recent orders.

EA Engineering, Science, And Technology, Inc., PBC dominates the award base, holding 25 of 50 task orders valued at $78.2 million combined potential—roughly 37% of the vehicle's active value. Seres-Arcadis SB JV and AECOM Technical Services follow with $48.9 million and $50.6 million respectively. The top three firms account for approximately 78% of awarded task-order potential value. The remaining six primes and small business pool are thinly distributed.

Baltimore District controls 94% of task-order funding; three other USACE districts and Finance account for the remainder. The set-aside mix is approximately 72% unrestricted and 28% total small business, with no exclusive small-business reserve at the vehicle level despite initial solicitation language reserving up to six contracts for small firms.

Task-order values range from $40 thousand to $32.6 million potential, with firm-fixed-price dominance. Mega-orders include PFAS remedial investigations nationwide ($32.6 million potential), multi-site CERCLA work at Fort George G. Meade ($10.9 million), and optimized remediation contracts for regional clusters ($17.3 million and $5.6 million potential). Many orders span three to five years with option periods.

The US Army Corps of Engineers (USACE), Baltimore District, has awarded a Multiple Award Environmental Services (MAES 2017) contract. MAES 2017 is intended to provide environmental services in the areas of environmental cleanup and quality for military and civil programs.

The geographic area of coverage will be primarily the NAD mission area with incidental utilization within CONUS, Hawaii, Alaska, and Puerto Rico. Work may include ancillary Ordnance and/or Radioactive materials and subsequently the remediation of munitions response site and radiological sites.
