Chief Joseph Dam

The U.S. Army Corps of Engineers seeks information on firms able to perform spillway gate lifecycle maintenance at 2,620-MW Chief Joseph Dam on the Columbia River in Washington. Responses are due April 18.

Chief Joseph currently is undergoing refurbishment of 10 Francis turbines to increase their rated output and peak efficiency. The Corps' Seattle District recently awarded a contract to Holt Services Inc. for drilling to replace inclinometers monitoring a landslide on the left bank of the project. It took bids April 8 to supply turbine packing box lantern rings for the project.

In a sources sought notice, the Corps' Seattle District now seeks information on firms with the capability to perform lifecycle maintenance on Chief Joseph's 19 spillway gates, which measure 60 feet tall by 35 feet wide. Responses are to help the Corps determine the type of solicitation to be issued.

Work includes replacement of wire rope and gate seals, gate recoating, gearbox inspection and rehabilitation, design and fabrication of rail system and trolley systems, cathodic protection, flushing and oil replacement in seal heaters, removal of backing bars and weld repairs. The work is valued at $5 million to $10 million.

The sources sought notice may be obtained from the Federal Business Opportunities Internet site, www.fbo.gov, by entering solicitation No. W68MD940168424 in the "Keyword/Solicitation #" box.

Responses are due by April 18 by e-mail to the address below. For information, contact Jenny J. Scroggins, U.S. Army Corps of Engineers, Seattle District, Attn.: CENWS-CT, P.O. Box 3755, Seattle, WA 98124-3755; (1) 206-764-6696; E-mail: jennifer.j.scroggins@usace.army.mil.
