Brosamer & Wall/Tutor Perini Joint Venture are awarded $177 million contract to begin phase 1 of the half-billion dollar Friant-Kern Canal subsidence project
SACRAMENTO – Subsidence by groundwater extraction has all but led to a conveyance failure for parts of the Friant-Kern Canal. After years of vying for funding to fix its most impacted 33-mile stretch, the Friant Water Authority announced they have awarded a contract to Brosamer & Wall/Tutor Perini Joint Venture for phase one of the project.
Brosamer & Waller, based in Walnut Creek, was awarded a $177 million contract to perform the construction aspects of the first phase of work to repair the Friant-Kern Canal along the significant stretch. This portion of the canal has lost more than half of its capacity due to subsidence—a sinking of the earth from groundwater extraction.
“After more than four years of work to assess the canal’s problems, develop designs to fix it, and assemble an initial funding and financing package, we are thrilled to take this enormous step toward restoring critical water deliveries that support the San Joaquin Valley’s businesses, communities, and farms,” Friant Water Authority’s chief executive officer Jason Phillips said. “FWA looks forward to launching this phase of work with our partners at Reclamation and Brosamer & Wall/Tutor Perini Joint Venture.”
The total project is estimated to cost around $500 million and will eventually restore water delivery to over one million acres of farmland and 250,000 residents in California’s eastern San Joaquin Valley.
“Repairing this portion of the Friant-Kern Canal provides significant improvement for the canal’s conveyance capacity and is a key priority for Reclamation and the Central Valley Project,” reclamation regional director Ernest Conant said. “We are looking forward to working with FWA and Brosamer & Wall/Tutor Perini Joint Venture to have shovels in the ground by the end of the year—a significant step to providing reliable water supplies to farms and communities throughout the eastern San Joaquin Valley.”
Brosamer & Wall/Tutor Perini Joint Venture was selected through a best-value competitive bid process overseen and managed by Reclamation throughout the summer. Reclamation anticipates a notice to proceed for the contractor in November with resulting construction activity beginning by year’s end. Although the contract will be managed by Reclamation, FWA and Reclamation will work jointly with Brosamer & Wall/Tutor Perini Joint Venture to implement construction of the Friant-Kern Canal Middle Reach Capacity Correction Project. The work under this contract includes 10 miles of new canal with eight concrete inverted siphons below various structures and creeks along with various concrete turnout structures, and other miscellaneous work.
