Nationwide Environmental Engineering Services

The Department of Homeland Security US Coast Guard awarded this Master IDIQ for nationwide environmental engineering services covering construction, demolition, repair and maintenance, hazardous materials management, pollution prevention, dredging, and operational activities across Coast Guard shore infrastructure and real property. The last date to order is December 17, 2028, providing approximately 2 years and 5 months of remaining ordering authority under a shared ceiling of $75 million.

The vehicle was established on December 19, 2018, and has generated 175 task orders since its inception, with ordering momentum holding steady at roughly 20–23 orders per year over the past five years; nine orders have been awarded so far in 2026 as of June 10. The combined potential value of all awarded task orders stands at $93.2 million, of which $89.9 million (96%) has been obligated, leaving minimal unobligated capacity. This indicates the vehicle is heavily committed relative to its shared ceiling.

Work is predominantly unrestricted; 98% of orders carry no set-aside designation. The remaining 2% splits between small business set-asides and one 8(a) sole-source order. Arcadis U.S., Inc., dominates by potential value with 26 orders worth $21.6 million, followed by Brice Engineering, LLC, with 15 orders totaling $20.5 million, and Tetra Tech, Inc., with 28 orders valued at $11.9 million. These three firms, along with WSP USA Environment & Infrastructure Inc. (44 orders, $11.4 million) and Leidos, Inc. (9 orders, $11.8 million), account for 83% of combined potential value across the vehicle. All 175 orders serve a single customer: the Coast Guard.

Recent task orders show typical scope: environmental site assessments, remedial investigations, preliminary assessments, NEPA compliance and environmental assessments, RCRA groundwater monitoring, pollution prevention guidance, hazardous materials surveys (lead-based paint, asbestos), historic property evaluations, NPDES permitting support, and dredging permitting. Task-order values cluster in the range of $30,000 to $1 million, with occasional larger efforts. The largest recent order awarded December 15, 2025, to Tetra Tech for site investigation and remedial design at Cape Flattery Light Station, Tatoosh Island, Washington, carries a ceiling of $2.777 million. A nationwide PFAS site inspection effort awarded September 19, 2023, to Leidos carries $8.218 million. Work spans domestic and overseas USCG facilities, including remote sites in Guam, American Samoa, and the Marshall Islands; the majority of recent awards target East Coast and West Coast bases, training centers, and lighthouse stations.

USCG shore infrastructure, real property, and other projects cover a wide range of activities, including but not limited to construction, demolition, repair and maintenance; hazardous materials management; pollution prevention; dredging; operational activities (e.g., training, permitted, and response activities); and real property agreements/transfers.
