The U.S. Army Corps of Engineers is seeking potential suppliers for diesel-powered mobile air compressors for the McNary Lock and Dam, with the work to be performed at that location in Walla Walla. This is a sources-sought notice to identify capable businesses for a future Firm Fixed Price contract, not an active solicitation. Interested firms must submit a capabilities package, including their business size, product specifications, and feedback on the technical requirements. The response deadline for this market research is 11:00 AM Pacific Time on April 6, 2026. No budget or specific project timelines are detailed in this announcement.
