How to bid on PH2 BLADE SEALS REPLACEMENT for Bonneville Dam, DEPT of Defense
What the agency is buying and why it matters
The U.S. Army Corps of Engineers, Portland District, Bonneville Lock and Dam, needs a contractor to supply and install new blade seals for the five-bladed Kaplan turbine in Bonneville Dam Powerhouse II Main Unit 16. There is an option for a second set of blade seals for Unit 17.
This work is critical for maintaining the operational efficiency of the Bonneville Dam. The government is looking for expedited fabrication, delivery, and installation after the contract is awarded. This is a chance for businesses specializing in turbine components and industrial sealing solutions to work on a significant infrastructure project.
Key dates and what happens at the deadline
This solicitation was published on September 11, 2026. All responses must be submitted by September 25, 2026, at 9:00 PM ET. This is a firm deadline, and late submissions are typically not accepted.
The government anticipates awarding the contract around September 30, 2026. This date is for planning purposes only and does not change the contractor's performance obligations, which begin upon contract award.
Who this opportunity suits
This opportunity is suitable for firms with expertise in manufacturing and installing specialized industrial seals, particularly for large-scale hydroelectric turbines. Experience with Kaplan turbines and working within dam environments would be highly beneficial.
The contractor will be responsible for designing and fabricating one-piece solid seals with redundant sealing edges, without splits, and field-molded solid at the site. The seals must be bonded without external adhesive or elastomer. Firms with a strong background in precision manufacturing and on-site installation of custom components will find this a good fit. The relevant category is supplies, specifically specialized industrial components.

Tips for preparing a competitive response
Carefully review all provided drawings and dimensions, especially those referenced in the solicitation, such as 4296-JL-1 and 6532-T-2. Pay close attention to the material compatibility requirements for the outer (cast steel) and inner (stainless steel) surfaces the seal will be against.
Emphasize your firm's capability to meet the expedited fabrication, delivery, and installation schedule. Clearly detail your proposed methodology for designing, fabricating, and installing the one-piece solid seals, ensuring you address the requirement for no gluing, cold bonding, or hot bonding with additional material. Provide a clear plan for verifying final seal dimensions prior to delivery and installation, as the approximate dimensions are for pricing purposes only.
