The U.S. Army Corps of Engineers is conducting market research to identify vendors capable of providing site assessments, blast analyses, and security recommendations for select U.S. sites. This is a Request for Information only, not a solicitation, and responses will be used for planning purposes. Interested parties must submit their responses by 1:00 PM Central Standard Time on 26 May 2026. No budget information is specified, and the location for performance of services is not detailed beyond select sites across the U.S. Vendors should review the draft Performance Work Statement and provide capability statements, security clearance status, and business size information.
