Corps seeks bids for lamprey passage in fish ladder at 980-MW McNary

Pacific Lamprey

The U.S. Army Corps of Engineers seeks bids from small businesses for a prototype lamprey entrance structure in a fish ladder at 980-MW McNary Dam on the Columbia River. Bids are due Aug. 2.

The Corps' Walla Walla District invited registration in June for a planned site visit. It sought information in November on small businesses capable of installing a prototype lamprey entrance structure in a McNary fishway on the Oregon shore. The U.S. Forest Service took bids July 1 to perform a fish habitat study for lamprey upstream of 11-MW Soda Springs Dam on Oregon's North Umpqua River.

In a solicitation set aside for small businesses, the Corps now seeks bids for fabrication and installation of a prototype lamprey entrance structure in the Oregon shore fishway at McNary. The entrance structure is composed of modular aluminum devices that include a new entrance flume, two baffle boxes, and a trashrack. The contractor is to demolish and remove existing structures including stoplogs and is to remove then reinstall an access bridge and telescoping weirs and associated machinery.

The work is valued at between $500,000 and $1 million.

A solicitation notice may be obtained from the Federal Business Opportunities Internet site, www.fbo.gov, by entering Solicitation No. W912EF13B0005 in the "Keyword/Solicitation #" box.

Bids are due Aug. 2. For information, contact Caroline B. Mueller, Contract Specialist, U.S. Army Corps of Engineers, Walla Walla District, CENWW-CT, 201 N. 3rd Ave., Walla Walla, WA 99362-1876; (1) 509-527-7225; E-mail: caroline.b.mueller@usace.army.mil.
