About this file
This package includes plans and specifications for upgrading pumps at the McNary Lock and Dam Levee Drainage Pump Station in Oregon and Washington. The solicitation calls for replacing three existing pumps with new pumps compatible with the existing electrical and mounting arrangements. Bidders should field verify key dimensions for clearance through access openings and to existing piping connections. The specifications provide pump performance curve requirements and details for mounting the pumps on expansion-type couplings to allow for misalignment. The contract will be awarded by the US Army Corps of Engineers Walla Walla District under solicitation number W912EF23B0002.
