The Department of Defense, through the US Army Corps of Engineers, Walla Walla District, is seeking sources for the fabrication and delivery of a Navigation Lock Unwatering Pump Platform for the McNary Lock and Dam in Umatilla, Oregon. The project requires the fabrication of structural steel components, including columns, beams, guardrails, gates, and fall protection anchors, all of which must meet specific tolerances and standards, including hot-dipped galvanization and compliance with AWS D1.1/D1.1M standards. This sources sought notice aims to identify capable small businesses that can fulfill these requirements, with interested firms required to submit their business size, past project experience, and other relevant details to the primary contact, Kristin Kreutzer, at kristin.n.kreutzer@usace.army.mil. This opportunity is not a solicitation but a preliminary step to gauge interest and capability, with no commitment from the government to procure supplies at this stage.
