Bids sought to stabilize intake monoliths at 1,038-MW Wanapum

Grant County Public Utility District seeks professional engineering consulting services to stabilize intake structure monoliths for five future generating units at 1,038-MW Wanapum Dam. Proposals are due Feb. 21.

Wanapum Dam, part of the 1,893-MW Priest Rapids project on the Columbia River in Washington, features ten existing units. (HNN 2/1/08) Intake structure monoliths were constructed for five more units that were planned but have never been scheduled for installation.

Grant County PUD questions the condition of post-tensioned anchors that tie the monoliths to the underlying bedrock. Therefore, the utility intends to further stabilize the future unit intake structures to support normal loads. It also plans to stabilize the structures against severe and seismic loads.

The PUD anticipates the contract for its Wanapum Dam Future Unit Intake Stabilization Project would include assessment, evaluation, analysis, design, preparation and review of construction documents, and construction support. Construction support would include bid evaluation, document review, and on-site construction reviews and inspections. The contract period is expected to run through May 2014.

Bid documents for solicitation No. 330-2545 are on the Internet at http://grantpud.ebidsystems.com. Registration in the electronic vendor system is required to obtain documents.

Proposals are due by 2:30 p.m. Feb. 21 to Grant County Public Utility District, Attention: Contract Officer Jay Taylor, 15655 Wanapum Village Lane S.W., Beverly, WA 99321. Direct questions about technical aspects of the solicitation to Randy Nash, (1) 509-754-5088 ext. 3144, and other questions to Taylor, (1) 509-793-1468.
