Architect Engineer Environmental Support Services

The Architect Engineer Environmental Support Services (AEESS) is a multiple-award Indefinite Delivery/Indefinite Quantity (IDIQ) contract vehicle established by the U.S. Army Corps of Engineers (USACE) Louisville District to provide comprehensive environmental engineering services. The contract vehicle supports environmental investigations, assessments, remediation, and compliance activities primarily within the Great Lakes and Ohio River Division's mission boundaries, though services may be required nationwide. The vehicle enables USACE to rapidly procure environmental engineering expertise across multiple disciplines, including hazardous waste remediation, site investigations, environmental compliance, and specialized technical assessments for federal agencies including the Department of Defense, Environmental Protection Agency, and other federal entities.

Task orders under this IDIQ typically range from $100,000 to $1 million, with contract periods spanning approximately five years. Frequent prime contractors include Leidos, Inc., AECOM Technical Services, Jacobs Engineering Group, and Tetra Tech, who execute task orders involving complex environmental projects such as remedial investigations, per- and polyfluoroalkyl substances (PFAS) assessments, environmental impact statements, and site restoration efforts. The task orders frequently support military installations across states like Illinois, Indiana, Kentucky, Michigan, Ohio, and Pennsylvania, with most contracts being firm fixed-price and without specific small business set-aside designations. Common funding agencies include the U.S. Army Corps of Engineers, Air Force Civil Engineer Center, and other Department of Defense components, with work encompassing activities like environmental site assessments, groundwater investigations, feasibility studies, and regulatory compliance documentation.
