(Darin Oswald) Fish ladders at the the Lower Granite Dam had water that was too warm for salmon, but turbine manipulation saved the day. The U.S. Army Corps of Engineers seeks bids to replace HVAC equipment at the 810-MW Lower Granite Dam hydroelectric project on the Snake River in Washington. A site visit is scheduled Aug. 19, with bids due Sept. 3.

The Corps' Walla Walla District called for bids in June to build fishway temperature improvements and to replace turbine hub linkage components at Lower Granite. It took information in July on small businesses able to perform fish counting services at Lower Granite and seven other federal hydroelectric projects on the Columbia and Snake rivers.

The Walla Walla District now seeks bids to replace heating-ventilation-air conditioning equipment at Lower Granite that is either malfunctioning or does not meet current operational requirements. Work includes replacing the central powerhouse heating and cooling system, five constant volume HVAC systems, an open direct digital control system and electrical upgrades.

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

A solicitation notice may be obtained from the Federal Business Opportunities Internet site,, by entering Solicitation No. W912EF15B0015 in the "Keyword/Solicitation #" box. A site visit is scheduled Aug. 19.
