The general contractor that managed construction of San Francisco’s troubled $2.2 billion transit terminal is suing the agency in charge of the project alleging faulty design and mismanagement.
The joint venture of Webcor Builders and Obayashi Corp. filed the lawsuit Tuesday in San Francisco.
The lawsuit claims design and planning mistakes sent construction soaring and led to costs overruns that cost the joint venture $150 million.
The contractor said it submitted 12,000 requests for information and 1,603 change order requests to officials with the Transbay Joint Powers Authority during construction of the terminal in downtown San Francisco.
The project has been mired in litigation.
The terminal closed last month after cracks were found in steel beams.
Agency spokeswoman Christine Falvey did not immediately return a phone message Wednesday seeking comment.
