Kiewit Infrastructure West has won a $275M contract from the California Department of Water Resources to repair Oroville Dam’s spillways in California, US.

Kiewit Infrastructure bid was the lowest for the project — DWR has also received bids from Barnard Ames JV and Oroville Dam Constructors.

 “DWR is implementing its recovery plan to ensure the system can safely accommodate potentially heavy inflows from the Feather River watershed to Lake Oroville and subsequent releases from the lake,” said DWR in a statement.

The construction company will commence the repair work immediately in order to have the system operational by 1 November, the traditional start of the winter rainy season.

Work has already started on parts of the ‘no regrets’ work, such as road construction and slope stabilisation in and around future work areas, which needs to be finished regardless of the spillway recovery design decisions.
