Dworshak Dam on the North Fork Clearwater River in Idaho.
With a height of 717 feet , Dworshak is the third tallest dam in the United States and the tallest straight-axis concrete dam in the Western Hemisphere. The U.S. Army Corps of Engineers seeks bids to replace generator windings of the Unit 3 turbine-generator at the 402-MW Dworshak Dam hydroelectric project in Idaho. Bids are due July 8.

The Corps' Walla Walla District previously scheduled a site visit for June 2. Last year the district requested information on firms able to perform the windings replacement as well as cavitation repair of Dworshak Unit 3. It called for bids in May to supply circuit breakers and capacitors and in April for oil filtration systems for Dworshak on the North Fork Clearwater River.

The Walla Walla District now seeks bids to disassemble Unit 3, provide and install a new stator core and winding, and reassemble and commission the unit.

The work is expected to cost between $10 million and $25 million.

A solicitation notice may be obtained from the Federal Business Opportunities Internet site,, by entering Solicitation No. W912EF15R0019 in the "Keyword/Solicitation #" box. The site visit is scheduled June 2.

Bids are due July 8. For information, contact Jani Long, U.S. Army Corps of Engineers, Walla Walla District, 201 N. Third Ave., Walla Walla, WA 99362-1876; (1) 509-527-7209; E-mail:
