The U.S. Army Corps of Engineers seeks bids to supply intake gates and draft tube bulkheads for turbine maintenance at 2,160-MW John Day Dam on the Columbia River in Oregon. A new site visit is scheduled Sept. 10, with bids due Sept. 23.
The Corps’ Portland District previously scheduled a site visit May 13. It requested information last year on firms able to perform the work. It took bids Aug. 28 to fabricate and supply a turbine maintenance platform.
The Portland District now seeks bids to fabricate, deliver and assemble three intake gates (four sections make one gate) and two draft tube bulkheads (three sections make one bulkhead) to isolate main turbine-generator units so they can be dewatered for maintenance or repair.
The intake gates are to be placed on the upstream side of a unit and the bulkheads are to be placed on the downstream side. The largest intake gate section is to be 22.5 feet wide by 12.5 feet tall. The largest draft tube bulkhead is to be 36 feet 10 inches wide by 11.5 feet tall.
A solicitation notice may be obtained from the Federal Business Opportunities Internet site, www.fbo.gov, by entering solicitation No. W9127N15R0009 in the “Keyword/Solicitation #” box. The site visit is scheduled at 9 a.m., Pacific time, Sept. 10. Those planning to attend must contact by e-mail David Mackintosh, firstname.lastname@example.org, at least 72 hours before the visit.
Bids are due by 2 p.m., Pacific time, Sept. 23. For information, contact Robbie Newland, U.S. Army Corps of Engineers, Portland District, Contracting Division (CECT-NWP), P.O. Box 2946, Portland, OR 97208-2946; (1) 503-808-4634; E-mail: email@example.com.
