Contractor wins LA water tunnel on second attempt

A subsidiary of Tutor Perini Corporation is set to be awarded a US$121m tunneling project for Los Angeles County Department of Water & Power after twice submitting the lowest bid.

Frontier-Kemper’s bid was the lowest submitted in the rerun of the tender for the US$121m River Supply Conduit Improvement Upper Reach – Unit 7 project (RSC Unit 7). The company had also provided the lowest bid when the project was originally tendered earlier this year. The client had subsequently opted to re-bid the project; Frontier-Kemper has again been designated as the low bidder.

The project is funded by the Drinking Water State Revolving Fund, administered by the United States Environmental Protection Agency and the State Water Resources Control Board. The scope of work involves installation of approximately 13,260 lineal feet of 78-inch welded steel water line (WSWL), of which 11,810 feet will be installed inside a tunnel shored with bolted and gasketed precast concrete tunnel segments. The remainder will be installed by microtunneling (490 feet) and cut-and-cover methods (960 feet).

Work is expected to begin in October 2018 with substantial completion anticipated in December 2021.
