The US Army Corps of Engineers Walla Walla District is developing an acquisition to expand the generation capability of Dworshak Dam by installing a fourth generating unit and associated powerhouse structure extension. This will be a firm-fixed-price design-build contract. Industry day one-on-one sessions will be conducted virtually on May 4-5 and May 11, 2026, to share information on requirements and acquisition strategy, and to obtain industry feedback. Registration for these sessions, including company name, attendee names, contact numbers, and email addresses, must be provided by April 28, 2026. Questions for the government should also be submitted by April 28, 2026. Project Labor Agreement (PLA) questions must also be submitted by April 28, 2026. The scope includes powerhouse building extension and site development, turbine generator design, supply, installation, and commissioning, and balance of plant design and construction of auxiliary systems. Construction is estimated to begin in June 2028. The project site has limited space, and operations must minimize disruption to existing operations. The government is seeking industry recommendations on making the design-build approach successful, identifying primary risks, and strategies to minimize costs related to prime contractor markups on turbine generator pricing. They are also interested in how a Defense Priorities Allocation System (DPAS) rating would influence execution and willingness to bid. Information on long-lead items, contracting considerations, proposal time length, and the potential benefit of a stipend for proposals is also requested. The government is considering providing a Revit model of the existing facility and is asking for recommendations on other documentation of existing conditions and the preferred duration for an advance industry review of the solicitation. Design process questions focus on structuring post-award design reviews and dividing scope for fast-tracking. Site development, temporary features, concrete delivery methods, and flexibility during construction are key considerations for the powerhouse extension and site work. Turbine generator questions address early design submittals, experience with specific components, integration of designs, cost optimization techniques, and spiral case over-pressure testing. Balance of plant questions focus on experience in operating power generation facilities, comfort with limited outages, installation of specific equipment, concerns about concrete embedding, and experience managing large workforces at remote locations. Transportation and timing/permitting issues for a large GSU transformer are also areas of interest. The PLA submission deadline is April 28, 2026.
The notice indicates that on-site construction is estimated to begin in June 2028, but a specific overall delivery deadline for the project is not explicitly stated.
The government is seeking information about companies' experience with similar projects, their ability to manage large workforces at remote locations, and their experience with specific equipment like Francis turbine runners and 300 MW generators. They are also interested in how companies would structure the design review process and divide scope among design packages.
The notice states that one-on-one sessions will be conducted virtually, and there is no mention of a mandatory or optional physical site visit.
The bid notice does not mention any requirement for sample submission.
The notice mentions that questions for the government should be provided no later than April 28, 2026, and Project Labor Agreement (PLA) questions also need to be submitted by the notice closing date of April 28, 2026. This date is likely the deadline for submitting inquiries or objections prior to the solicitation release.
