The Corps of Engineers has issued a request for proposals for temporary spillway weirs to be installed at 980-MW McNary Dam, on the Columbia River in Washington. The solicitation, issued somewhat later than forecast, calls for bids by Sept. 8.
The Corps seeks construction of temporary spillway weirs that are to be installed within spillway bulkhead and gate slots. There are 22 spillway bays at the dam; the temporary weirs are intended to fit interchangeably into the spillway main and emergency gate slots.
The weirs are to feature three individual steel assemblies inserted vertically into spillway gate slots, forming a shaped weir for water to flow over the top, passing to the tailrace below the dam.
A site visit is planned Aug. 24. Visitors must register by 3 p.m. PDT, Aug. 23, with Lana Birdsell, (1) 509-527-7226. While the site visit is not mandatory, the Corps expects bidders to visit the site.
Prospective bidders must register on the Central Contractor Registration Internet site, www.ccr.gov.
