AI Contract Overview
The U.S. Army Corps of Engineers, Portland District, is seeking bids for the repair and rehabilitation of Tainter Valve TV1 at The Dalles Lock and Dam under a firm-fixed price construction contract. The scope includes comprehensive structural repairs to address cracking, corrosion, and cavitation damage on the valve’s skin plates, girders, and other components as detailed in engineering drawings, with all welds required to meet AWS D1.1 standards. The fabricator must be AISC-certified in a relevant category with a fracture critical endorsement and possess five years of documented experience on similar projects. Component replacements include new top, bottom, and side seals along with all associated seal plates and hardware, installation of armor plates over cavitated areas, and replacement of oversized self-lubricating polymer bushings at the lifting eye and trunnion ends to correct warping, with specifications requiring dynamic bearing pressure of at least 10,000 psi and suitability for submerged marine environments. The valve must be removed from the navigation lock fill culvert, transported to a certified fabrication facility for repairs, and returned for reinstallation with precise dimensional control surveys conducted at removal, post-repair, and pre-reinstallation to ensure proper alignment. The contract has an estimated value between $1 million and $5 million and a performance period of 150 days following notice to proceed. Competition is unrestricted under NAICS code 237990 with a $45 million size standard, and the PSC is Z2KA for dam repair or alteration. Bids are due by August 19, 2026, following a solicitation release in mid-August 2026, with a site visit planned within 7 to 14 days after the solicitation is posted. The government intends to award without discussions but retains the right to conduct them if necessary. All offerors must be registered in the System for Award Management prior to submission and award. The point of contact for technical inquiries is Andrew Sprys and Justin Figueredo, with Michael Stearns available for small business assistance.

SYNOPSIS
The U.S. Army Corps of Engineers (USACE), Northwestern Division, Portland District (CENWP) will be soliciting repair and rehabilitation of one Tainter Valve (TV1) at The Dalles Lock and Dam (TDA). The proposed project will be a competitive, firm-fixed price (FFP) construction contract MATOC.
Project Scope:
The following information represents the project objectives: The scope of this project is to furnish all labor, materials, and equipment to perform the comprehensive rehabilitation of the Tainter valve. The reinstallation work is to be performed inside of the navigation lock fill culverts.
The structural and weld repair scope includes the following items:
The repair of cracks, corrosion, and cavitation damage on the skin plate, girders, and other structural members as detailed in the engineering drawings provided with this bid advertisement.
Corroded sections of the Tainter valve, including areas where the existing paint system has failed, will need to be repaired per USACE specifications.
All structural welds must conform to AWS D1.1 standards. Contractors must factor in time for Government inspection, testing, and potential rework for rejected welds.
The fabricating plant and fabricator must be certified under the AISC (American Institute of Steel Construction) Quality Certification Program, and must be designated an AISC Certified Plant, Category CBR: Major Bridge Fabrication, IBR: Certified Bridge Fabricator - Intermediate, ABR: Certified Bridge Fabricator - Advanced or HYD: Certified Metal Hydraulic Fabricator with a fracture critical endorsement (FCE) at time of bid and for the duration of the contract. The fabricator or fabrication plant must possess five 5 years documented experience on projects of similar scope.
The component replacement and refurbishment scope includes:
Replacement of top, bottom, and side seals for the Tainter Valve being repaired as part of this scope of work. Replacement of these seals will also include the replacement of all seal plates and seal plate hardware.
The rehabilitation of the cavitated regions at the face of the downstream skin plate will require the installation of new armor’ plate sections to mitigate the potential for additional cavitation.
For TDA TV1, replacement and possible in-place machining of new, oversized self-lubricating bushings for the lifting eye and trunnion ends to correct for the warped condition of the gate. The self-lubricating bushings are of the fabric reinforced polymer type rated for use in submerged marine environments with a dynamic bearing pressure of at least 10,000 psi and must conform to the failure critical bearing requirements as per USACE specifications.
Replacement of these bushings will require close coordination with USACE personnel using information provided from the initial as-built survey of the Tainter valve to ensure correct alignment of the valve within the fill culvert.
Background: The U.S. Army Corps of Engineers requires the repair and rehabilitation of at least one Tainter Valve (TV1) at The Dalles Lock and Dam (TDA). The primary scope of work will address structural issues identified in engineering drawings provided by USACE. The identified structural issues include significant weld cracking, cracking of the Tainter valve skin plates, cavitation damage at the skin plates, advanced corrosion of structural members and failure of the finish paint system in some areas. It is anticipated additional structural damage will be identified during the repair of the Tainter valve.
The rehabilitation and repair of the Tainter valves in question will include the removal and replacement of the valve seals, seal plates, seal plate hardware and the installation of a new set of armor plates overlaid on the regions of cavitation damage at the seal plate bolts.
Additional requirements for this scope of work include the removal, handling, transport and delivery of the damaged Tainter Valve from the Navigation Lock to a fabrication shop for repair of the aforementioned structural deficiencies. Upon repair, the Tainter valve in question are to be transported back to the project site for reinstallation. The responsible contractor will also need to provide as-built dimensional control survey of each valve upon a) removal, b) completion of the repair work at the fabrication shop and c) immediately prior to reinstallation of the valve at the Navigation lock fill chamber. This condition necessitates the replacement of bushings and requires as-built surveying to ensure proper fit upon reinstallation
Contract Period of Performance: The estimated Period of Performance for this contract is to be completed 150 days after Notice to Proceed (NTP).
Magnitude of Construction: The estimated magnitude of construction is between $1,000,000 to $5,000,000.
Set Asides and Codes: Full and Open Competition - Unrestricted. The North American Industrial Classification Code (NAICS) for this potential requirement would be 237990, “Other Heavy and Civil Engineering Construction”. The related size standard is $45M. The Product Service Code (PSC) is Z2KA - Repair or Alteration of Dams.
Selection Process: Invitation for Bids.
Site Visit: A site visit will occur 7-14 days after solicitation is posted.
Discussions: The government intends to award without discussions but reserves the right to conduct discussions if deemed to be in the government’s best interest.
