WALLA WALLA, Wash., U.S. 6/7/12 (PennWell) — The U.S. Army Corps of Engineers seeks bids for roller chains and other equipment for extended submersible barrier screens at 980-MW McNary Dam on the Columbia River. Bids are due June 20.
The Corps’ Walla Walla District took bids in February for submersible power cable for the screens.
The Corps now seeks bids to fabricate and deliver stainless steel roller chains, connecting links, drive chain sprockets, lower radius take-up track pieces, sweep tube brushes and guides, control arm pins, drive shaft coupling pieces, and an arbor press for the screens at McNary, near Umatilla, Ore.
A solicitation notice may be obtained from the Federal Business Opportunities Internet site, www.fbo.gov, by entering Solicitation No. W912EF12R0027 in the “Keyword/Solicitation #” box.
Bids are due June 20. For information, contact Vicky Challis, Contract Specialist, U.S. Army Corps of Engineers, Walla Walla District, 201 N. Third Ave., Walla Walla, WA 99362-1876; (1) 509-527-7210; E-mail: email@example.com.
Corps to take bids for welding on McNary emergency gate bulkheads
The Corps’ Walla Walla District also plans to take bids from small businesses capable of performing welding repairs on emergency intake gate bulkheads at McNary.
The Corps solicited information in February about firms capable of performing the work. The Corps also solicited information in December about firms capable of performing other emergency intake gate work related to fish screen installations at McNary.
In the latest solicitation, the Corps said that, prior to 1995, emergency intake gate bulkheads 1 and 3 were torch cut into four pieces. Later the sections were re-welded, though the bulkheads have been out of service since 2006. Ultrasonic testing in 2007 revealed the welds to be unsatisfactory.
The Corps plans to take bids from small firms capable of repairing the 24- by 54-foot bulkheads and making them ready to place back in service. Valued at $250,000 to $500,000, the work is to be performed between July and September.
A pre-solicitation notice may be obtained from the Federal Business Opportunities Internet site, www.fbo.gov, by entering Solicitation No. W912EF12B0010 in the “Keyword/Solicitation #” box.
