Architect-Engineering Hazardous Toxic and Radioactive Waste

The Department of the Army Corps of Engineers Engineering District New England established a Master IDIQ for architect-engineering services on hazardous, toxic, and radioactive waste (HTRW) investigations, design, and construction support, with ordering authority through November 29, 2027. The vehicle carries a combined potential value ceiling of $90 million across a 3-to-6 small-business multiple-award pool, unrestricted by set-aside at the vehicle level, though individual task orders show mixed set-aside designations.

Approximately 16 months of ordering authority remains. The vehicle was established in November 2022 and has issued 20 task orders to date, with momentum declining from 9 orders in 2022 to 1 order thus far in 2026. Combined task-order potential value stands at $25.9 million, with $16.5 million (64%) obligated, indicating $9.4 million in remaining commitments against the $90 million ceiling.

Scope centers on remedial investigations, feasibility studies, proposed plans, records of decision, monitoring well development, PFAS investigations, groundwater management, and design-phase services at contaminated sites, particularly former military installations and National Guard bases. Work is geographically scoped to New England and New York districts (Maine, New Hampshire, Vermont, Massachusetts, Connecticut, Rhode Island, New York, and New Jersey) with potential expansion to other North Atlantic Division and assigned CONUS mission areas.

Competition is moderately concentrated. WSP USA Environment & Infrastructure Inc. dominates with 4 orders worth $15 million in combined potential value—nearly 58% of all potential value across the vehicle. SRS Battelle JV, LLC, EAS E&E JV, LLC, and Mabbett & Associates, Inc. hold the next tier, with the remainder distributed across a tail of nine firms. Ordering is heavily concentrated with the Engineering District New England itself, which accounts for 19 of 20 task orders ($25.6 million potential value); a single Army-level order represents the remainder.

Set-aside distribution reflects the small-business pool mandate: 85% of orders (17) carry no set-aside, while 15% (3) are designated Total Small Business. Task-order values typically range from $300 thousand to $10.5 million in potential value, with a notable multi-year effort at Cold Regions Research Engineering Laboratory, Hanover, New Hampshire, carrying a $10.5 million ceiling. Firm-fixed-price pricing dominates. Performance is distributed across multiple New England and Mid-Atlantic sites with no single geographic concentration beyond the regional scope.

The work includes, but is not limited to, various environmental studies, investigation, design, and construction phase engineering services for HTRW sites/projects. AE Services that may be required under this contract include but are not limited to work plans, Quality Assurance Project Plans (QAPP) in accordance with Uniform Federal Policy (UFP), environmental baseline studies, hazard evaluations, preliminary site assessments, site investigations, subsurface exploration (soil, sediment, and groundwater), indoor air and soil vapor investigations and mitigation, geological, geotechnical, and geophysical (surficial and borehole) investigations, surveying (topographic, aerial, and other), mapping (creating 2-dimensional and 3-dimensional data visualizations using software tools), geographic information systems (GIS), wetlands determinations and mitigation studies, conceptual site model development, environmental chemistry data collection and analysis. Work will primarily be performed within the boundaries of the New England (ME, MA, CT, RI, NH, VT) and New York Districts (NY and NJ), but work may also be required at other locations within the boundaries of the North Atlantic Division and assigned CONUS mission areas (ME, NH, VT, MA, CT, RI, NY, PA, NJ, DE, MD, VA, WV, and the District of Columbia).
