Frontier-Kemper announces $121m low bid for LADWP tunnelling project
August 09, 2018 – Frontier-Kemper Constructors, a subsidiary of civil, building and specialty construction company Tutor Perini, has announced a low bid for the $121m River Supply Conduit Improvement Upper Reach – Unit 7 Project (RSC Unit 7) of the Los Angeles County Department of Water and Power (LADWP).
The project was bid earlier in 2018 in which Frontier-Kemper provided the low bid. The customer later opted to re-bid the project, and Frontier-Kemper again emerged as the low bidder.
The project is funded by the Drinking Water State Revolving Fund, which is administered by the US Environmental Protection Agency and the State Water Resources Control Board.
The scope of work involves installation of 13,260 lineal feet of 78-inch welded steel water line (WSWL), 11,810 lineal feet inside a tunnel shored with bolted and gasketed pre-cast concrete tunnel segments.
Nearly 490 lineal feet of microtunnel for 78-inch WSWL and approximately 960 lineal feet of 78-inch WSWL will be installed by cut-and-cover methods.
Work is expected to commence in October 2018 and substantial completion is anticipated in December 2021.
The contract value is expected to be included in the company’s third quarter 2018 backlog.
In July 2018, Tutor Perini’s subsidiary, Roy Anderson Corp, was awarded a $59m contract by the US Army Corps of Engineers for the construction of the Visiting Quarters at Joint Base Charleston, South Carolina, US.
The project involves construction of a new four-storey, approximately 149,000ft² building that will include 266 guest rooms, appropriate back of house areas, guest laundries, housekeeping function spaces, a multifunctional lobby, a business centre, conference rooms, an exercise room and restrooms, among other improvements.
The new Visiting Quarters will be Certified Silver under LEED for New Construction.
The company said that work will begin in the next 30 days with substantial completion anticipated in the summer of 2020. The contract value will be included in the company’s third quarter 2018 backlog, it said.
