Shimmick Construction Co. has been awarded a nearly $87 million contract to build Antioch’s brackish water desalination plant.
The City Council unanimously approved the company’s bid during a special meeting Friday after rejecting a protest bid from C. Overaa & Co., which also wanted the job. The $86,689,000 contract with Shimmick will include a 5% contingency of $4,334,450 in case of unforeseen costs for a total of $91,023,450.
In addition, council members authorized city staff to increase the total budget for the desalination project to $110 million. Earlier projections had estimated it would cost nearly $70 million.
