Lower Monumental Unit 2 Hub Seal Repairs

5 May 2021 -- Amendment 0001 posted. 

This procurement is unrestrcted. Competition is full and open. 

The U.S. Army Corps of Engineers, Walla Walla District intends to issue a construction solicitation for a project titled Lower Monumental Unit 2 Hub Seal Repairs.

The work is located at the Lower Monumental Dam in Franklin County, Washington.

Lower Monumental Unit 2 Hub Seal Repairs is a construction project to repair a failed seal between the runner hub and turbine shaft connection.  The Lower Monumental Main Unit 2 is a vertical hydroelectric turbine-driven generating unit, with the generator manufactured by General Electric and rated at 142,105 kVA. The turbine runner is a 6-blade Kaplan-type rated at 212,400 horsepower (90 rpm), manufactured by Baldwin-Lima-Hamilton.

This scope of work is to repair the leak found at the turbine shaft to hub flange location. It was determined that the o-ring between the top of the Kaplan hub and the shaft lower flange is the location of the leak. In lieu of replacing the failed o-ring (requiring unit disassembly), the scope of work is to contain leakage by sealing the outer diameter of the shaft flange where it meets the hub. It will also include welded caps for each coupling bolt, and piping at the shaft jacking bolts to contain leaking within the flange face and routing it back to the static oil head.  Optional work will include installation of Government furnished blades seals and nose cone gasket.  Following repairs to the Unit 2 leak, commissioning support will be required in bringing Unit 2 back to Kaplan.

TIME FOR COMPLETION:  The work shall be completed for Unit 2 to include all repairs, testing and inspections by no later than 150 calendar days following Notice to Proceed.

Performance and payment bonds will be required.  The magnitude of the project is estimated to be between $250,000 and $500,000.  Sustainability requirements will be contained in the solicitation and resulting contract.   The solicitation will be issued as an Invitation for Bids (IFB) with Definitive Responsibility Criteria in accordance with FAR Part 14. The IFB will result in award of a firm fixed-price contract. This acquisition will be subject to Federal Acquisition Regulations clause 52.225-9 Buy American-Construction Materials.  The proposal due date will be contained in the solicitation and any solicitation amendments that may be issued.  

This procurement is unrestricted.  Competition is full and open to large and small business concerns.  A small business subcontracting plan is not required.  The NAICS code for this procurement is 237990, Other Heavy and Civil Engineering Construction.  The small business size standard is $39,500,000.
