U.S. sets site visit for supply of intake gates, draft tube bulkheads at 2,160-MW John Day Dam

John Day Dam

The U.S. Army Corps of Engineers has scheduled a site visit with plans to issue a solicitation for intake gates and draft tube bulkheads for turbine maintenance at 2,160-MW John Day Dam on the Columbia River in Oregon. The site visit is scheduled May 13, with the solicitation expected in early May.

The Corps' Portland District requested information last year on firms able to perform that work, to fabricate and supply a turbine maintenance platform and to upgrade Kaplan turbines at John Day.

The Portland District said it plans to issue a request for bids in early May from firms 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 pre-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 10 a.m., Pacific time, May 13. Those planning to attend must contact by May 12 by e-mail Robbie Newland, robbie.newland@usace.army.mil; David Mackintosh, david.c.mackintosh@usace.army.mil; and John Day Security, JDSecurity@usace.army.mil, with information on those planning to attend.

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) 503-808-4629; E-mail: robbie.newland@usace.army.mil.
