- MNA Levee Drainage Pump Upgrade Federal contract opportunity
- Solicitation number
- W912EF23B0002
About this file
This package contains plans and drawings for a final equipment upgrade at levee drainage pump stations along the Columbia River in Oregon and Washington. The upgrade work includes replacing permanent power with temporary power skids, upgrading pump equipment, and installing a manual transfer switch for standby generator connection. Temporary power skids will provide power during demolition and construction activities, which will occur in stages to maintain operation of at least one pump at all times. The drawings provide details for the temporary power arrangement, one-line diagrams, and general scope of work notes.
The related federal contract opportunity is solicitation number W912EF23B0002 from the Department of the Army Corps of Engineers Walla Walla District. The solicitation is for a levee drainage pump upgrade at McNary Lock and Dam to replace equipment and upgrade systems at multiple pump stations along the specifications in the plans package.
