U.S. extends bidding for dam repair at 2,160-MW John Day hydro project

The U.S. Army Corps of Engineers has extended the deadline for bids for dam repair at 2,160-MW John Day Dam on the Columbia River in Oregon. Bids now are due Dec. 3.

The Corps previously called for bids by Nov. 28 to repair failed monolith waterstops at John Day. A bid due date for supply of electrical equipment remained unchanged at Nov. 18.

The Corps awarded a contract in October to Knight Construction & Supply Inc. to replace wire rope and perform load testing for an emergency intake crane at John Day. The agency took bids in September to refurbish thrust bearing shoes and thrust runners. It awarded a contract in 2012 to Skyward Construction to refurbish elevators at the hydro project.

In a solicitation set aside for small businesses, the Corps now seeks bids by Dec. 3 to repair failed monolith waterstops to significantly reduce the amount of water entering John Day Dam. Methods are to include pavement joint sealant, drilled socket waterstops, and surface mounted rubber gasket waterstops. Repairs are to be performed in the dewatered fishway, the roadway deck, and in several dam galleries.

That work is valued at $1 million to $5 million.

A solicitation notice may be obtained from the Federal Business Opportunities Internet site, www.fbo.gov, by entering solicitation No. W9127N14R0004 in the “Keyword/Solicitation #” box.

The Corps also seeks bids Nov. 18 from small businesses to replace and upgrade the DC and preferred AC system at the John Day powerhouse. Work is to include replacing and upgrading batteries, battery racks, charges, switchboards, panel boards, feeders, and feeder breakers of the system.
