The U.S. Army Corps of Engineers, Walla Walla District, intends to issue a sole source contract to Rockwell Automation Inc for the procurement of Allen-Bradley programmable logic controllers (PLC) and associated system components. This procurement is necessary to maintain the original manufacturer's warranty and licensing for existing Allen-Bradley 5380 controllers, which are critical for the operational efficiency of various hydroelectric projects, including the Millcreek and McNary dams. The use of Rockwell Automation products is essential for standardizing PLCs and ensuring compatibility and maintainability, as previous attempts to solicit competitive bids have not yielded viable alternatives. Interested vendors may submit documentation demonstrating their capability and past performance to Callie Rietfors at callie.rietfors@usace.army.mil or by phone at 509-527-7280, although this is not a request for competitive proposals. The streamlined procurement process is expected to continue until November 2028, reducing administrative burdens associated with repetitive contracts.
