Multiple Award Military Munitions Services II (MAMMS II)

The U.S. Army Corps of Engineers Baltimore District established a Master IDIQ for Multiple Award Military Munitions Services II (MAMMS II) on July 14, 2015, with a shared ceiling of $240 million, but ordering closed on July 13, 2020 and remains closed as of today. This vehicle is no longer available for new task orders.

MAMMS II contracted environmental remediation and munitions response services across the USACE North Atlantic Division mission area within the Continental United States. The vehicle executed 51 task orders between May 2016 and September 2020, with ordering activity peaking in 2018 and 2019 (13 and 15 orders respectively) before declining to 4 orders in 2020. Combined potential value across all task orders is $176.5 million, of which $151 million (86 percent) has been obligated.

The work spans remedial investigation and feasibility studies, remedial design and action, long-term monitoring, operational range assessments, time-critical and non-time-critical removal actions, and environmental compliance work at military installations and formerly used defense sites. Representative task orders include $37.9 million in potential value for Army National Guard PFAS remedial investigations nationwide (W912DR15D0018-W912DR18F0741), $18.2 million for site-wide remedial action at Spring Valley FUDS in Washington, D.C. (W912DR15D0022-W912DR17F0099), and $12.4 million for remedial design and action at Picatinny Arsenal in New Jersey (W912DR15D0018-W912DR20F0492).

Weston Solutions Inc. leads by potential value with $50.6 million across 11 orders; AECOM Technical Services follows with $39.4 million across 3 orders; Arcadis U.S. and Hydrogeologic each hold $34 million and $24.3 million respectively. These four firms represent 92 percent of combined potential value. Eight primes share the awardee base overall.

The Department of the Army Corps of Engineers Baltimore District placed 41 of 51 orders worth $152.7 million in combined potential value, representing the dominant customer. Other Army organizations and IMCOM placed the remainder.

Ninety-two percent of task orders carried no set-aside designation; four orders (8 percent) were set aside as Total Small Business, all of which are closed or nearing completion.

The US Army Corps of Engineers (USACE), Baltimore District has awarded a Master IDIQ for the Multiple Award Military Munitions Services II (MAMMS II) contract for munitions and environmental response services located primarily in the USACE North Atlantic Division (NAD) mission Area of Responsibility (AOR) within the Continental United States (CONUS).
