Alltech Engineering Corp has won a contract valued at over $11 million to repair the radial gates at the Nimbus Dam in California.
The project will involve the repair of 14 spillway gates and the construction of a bulkhead storage facility, with work to be completed in 2019. Work will include removing and disposing of the coating that potentially contains lead and other heavy metals and performing mechanical repairs on the nearly 70-year-old gates. The contract also calls for making concrete repairs to the dam's spillway and piers.
Nimbus Dam was constructed in 1956. The original steel wire ropes were replaced with stainless steel wire ropes in the 1980s, but other than normal maintenance, no major work has been done to the gates since the dam began operations. Four of the dam's 18 gates were repaired in previous phases. This will be the final contract for the remaining 14 gates.
“This construction project will help bring Nimbus Dam - a key feature of the Central Valley Project - up to date," said Acting Reclamation Commissioner Lowell Pimley "It will ensure the Nimbus Dam facility continues to operate at full capacity, while protecting and safeguarding environmental conservation and water-related recreational activities."
