The U.S. Army Corps of Engineers will accept bids Aug. 15 for coating and related work on Tennessee’s Cordell Hull Dam—a painting contract valued at up to $1 million.
The project involves cleaning, surface preparation and recoating five 41-foot-high, 45-foot-wide steel tainter gates at the dam, located at river mile 313.50 on the Cumberland River in Carthage, TN.
The dam, completed in 1973, is 93 feet tall and 1306 feet wide. Its five tainter gates can discharge 175,000 cubic feet of water per second.
Scope of Work
The gates will be abrasive blast-cleaned to SSPC-SP 5 (white metal) and recoated with an epoxy-urethane system. SSPC-QP 1 certification is required.
The existing coatings contain low levels of lead; containment will be required.
The contractor will also be responsible for removing and disposing of all wood, tires, buoys or other debris collected on the gates.
The Cordell Hull project is comprised of a navigation lock, a powerhouse, an embankment and a spillway section. The spillway section consists of the tainter gates mounted on concrete spillway piers and operated by an overhead gantry crane.

All work shall be field performed and must be done with water load removed from the gate. However, the project includes only enough bulkheads to dewater one gate at a time.
Because the entire dam area is closed to the public, the contractor must follow specified security measures.
