About this vehicle
Naval Facilities Engineering Command awarded this Master IDIQ for environmental remediation services of radiological contaminants at NAVFAC Southwest and NAVFAC Atlantic installations on March 14, 2017, with ordering authority that closed on March 13, 2022. The vehicle is no longer active; RADMAC III Environmental Multiple Award Contract, awarded May 8, 2025, is its successor. Ordering momentum peaked in 2018 with 14 task orders; recent activity dropped sharply to one order in 2020 and two in 2021 before a brief uptick to four orders in 2022, after which no new awards have been issued.
Combined potential value across 44 task orders stands at $312.4 million, with $280.1 million obligated (90% of potential value), indicating substantial execution across the vehicle's lifecycle. RSI Remediation and Aptim Federal Services dominate the competitive field: RSI holds 12 orders worth $143.5 million in combined potential value, while Aptim holds 15 orders worth $137.2 million. These two firms account for roughly 90% of all awards. ECC Insight Philotechnics, Aecom-Atkins Joint Venture, and WSP USA Environment & Infrastructure account for the remaining activity.
Work concentrates almost entirely within Naval Facilities Engineering Command (42 orders, $306.3 million combined potential value), with minimal work for broader Department of the Navy (two orders, $6.1 million). All 44 task orders are unrestricted—no set-asides were used across the vehicle. Task orders span radiological investigation, survey and characterization; remedial design and remedial action; operations, maintenance, and monitoring; and radiological controls and health and safety support. Notable large orders include radiological investigations and remedial actions at Hunters Point Naval Shipyard parcels valued in the tens of millions, basewide operations and maintenance contracts, and site characterization work at Alameda Point and other installations. Geographic performance spans NAVFAC Southwest and Atlantic footprints, with California installations (Hunters Point, Moffett, Alameda Point, Naval Base Point Loma) representing significant scope.
