Repair Tainter Valves at Various Locations

Newt Graham, W.D. Mayo, and Chouteau Lock & Dams, OK

This is a PRE-SOLICITATION NOTICE for the construction of the Repair Tainter Valves at Various Locations, at Newt Graham, W.D. Mayo, and Chouteau Lock & Dams, Oklahoma. THIS IS NOT A SOLICITATION FOR PROPOSALS AND NO CONTRACT WILL BE AWARDED FROM THIS SYNOPSIS. No reimbursement will be made for any costs associated with providing information in response to this pre-solicitation notice or any follow up postings.

The U.S. Army Corps of Engineers – Tulsa has been tasked to solicit for and award a contract for the Repair Tainter Valves at Various Locations project at Newt Graham, W.D. Mayo, and Chouteau Lock and Dams, Oklahoma. The proposed design-bid-build project will be procured as a competitive small business set-aside, firm-fixed price contract in accordance with FAR 15, Negotiated Procurement, using the Lowest Price Technically Acceptable approach.

Project Description:

The scope of this project is to perform maintenance and repair work on the two 12' x 12’ filling valves and two 12' x 12’ emptying valves (per location) located at Newt Graham L&D, W.D. Mayo L&D, and Chouteau L&D. The valves will be pulled out for repair, undergo blasting and painting, and then reinstalled. The repair work will include the replacement of seals, backing/bearing bars, hardware, strut and trunnion assembly pins, bushings, keeper bars, and other necessary components. Additionally, certain valves may require casting build-up and line boring to address specific issues, such as worn castings where the valve connects to the strut.

The work includes but is not limited to:

Task 1: Valve Removal

• Coordinate with lock operations to determine suitable timeframes for removing two valves (upstream and downstream) on the same side of the lock chamber while keeping the lock operational.


• Develop a valve removal plan, including safety protocols, equipment requirements, and coordination with lock personnel.


• Disconnect and remove the valves from the strut and trunnion assemblies.

Task 2: Valve Repair

• Assess the condition of each valve and identify specific repair requirements, such as seal replacement, backing/bearing bar replacement, hardware replacement, and strut and trunnion assembly maintenance.


• Address any casting issues, such as worn castings, through casting build-up and line boring as necessary.


• Conduct repairs using appropriate tools, techniques, and materials.


• Perform functional tests to ensure the repaired valves meet operational requirements.

Task 3: Valve Blast and Paint

• Prepare the valves for blasting by cleaning and removing debris or contaminants.


• Conduct blasting to remove existing coatings, rust, and corrosion from the valve surfaces.


• Apply suitable protective coatings, such as primer and paint, to enhance durability and corrosion resistance.

Task 4: Valve Reinstallation

• Coordinate with lock operations to determine suitable timeframes for valve reinstallation.


• Develop a valve reinstallation plan, including proper alignment and connection to the strut and trunnion assemblies.


• Install the repaired and painted valves, ensuring proper fit, alignment, and secure connections.


• Conduct operational tests to verify the valves' functionality after reinstallation.

In accordance with FAR 36 and DFARS 236, the estimated magnitude of construction for this project is between $5,000,000 and $10,000,000.

The North American Industry Classification System code for this procurement is 237990 (Other Heavy and Civil Engineering Construction) which has a small business size standard of $45M.

Estimated duration of construction of this project is 365 calendar days.

Anticipated solicitation issuance date is on or about 22 January 2025, and the estimated proposal due date will be on or about 25 February 2025.
