Description
The US Army Corps of Engineers (USACE) is seeking information from industry partners regarding the installation of a fourth generating unit (Main Unit 4) and associated powerhouse structure extension at the Dworshak Dam Powerhouse. The project involves design and construction of a powerhouse extension, turbine-generator, and balance of plant equipment. The government intends to utilize a design-build contract and is seeking feedback on the proposed approach. The project is expected to begin in June 2028 and will require coordination with other contractors and government agencies.
Key aspects of the project include:
• Powerhouse extension and site development
• Turbine-generator design and installation
• Balance of plant equipment installation
• Contractor access and work hour limitations
• Environmental controls to avoid oil spills and other impacts
• Coordination with other contractors and government agencies
The government is seeking information on industry experience, design and construction approaches, and potential risks and challenges associated with the project.
