About this opportunity
The U.S. Army Corps of Engineers, Portland District, issued solicitation number W9127N22B0002 to replace a damaged section of metal-enclosed bus duct at the Lookout Point Dam powerhouse. The bus duct between the Unit #2 breaker and Generator Step-Up transformer T2 requires replacement after being damaged in January 2020 when the transformer experienced a differential trip during a switching operation that triggered the fire protection deluge system. Bids were due by May 20, 2022 and the contract will be awarded based on lowest price technically acceptable.
The opportunity is set aside for total small business and involves furnishing and installing approximately 100 feet of new metal-enclosed bus duct. The estimated value of the contract is between $1 million to $5 million to be performed at the Lookout Point Dam facility in Lowell, Oregon. Seven bids were received by the opening date with the lowest from Gardner Zemke Company at $646,256. The government estimate was $1,345,741. NAICS code 238210 and PSC code 7240 apply.

The U.S. Army Corps of Engineers, Portland District, has a requirement to replace a damaged section of metal-enclosed bus duct at the Lookout Point Dam. Power is delivered from three hydropower generating units to the Bonneville Power Administration (BPA) at 115kV through three Generator Step-Up (GSU) transformers located on the downstream deck of the powerhouse and a 115kV breaker in the BPA switchyard. In January 2020, the GSU transformer T2 experienced a differential trip during a switching operation of the 115kV breaker that then triggered the fire protection deluge system at transformer T2. This water infiltration resulted in a ground fault and damage to the metal-enclosed bus duct between the Unit #2 breaker and the transformer T2.
