An $840 million contract for Muni’s Central Subway project — a pact that accounts for more than half the total cost of the undertaking — is up for approval Tuesday.
The San Francisco Municipal Transportation Agency’s board of directors is expected to vote on the contract, which includes the construction of three underground stations, an elevated platform and 1.5 miles of light-rail tracks. The stations are slated to be built underneath the Moscone Center, Union Square and Chinatown, and the platform will be located at Fourth and Brannan streets.
The agency’s staff has recommended that the project be carried out by the national firm Tutor Perini, which submitted the lowest of three bids at $840 million.
Even though the agency estimated the project work would only cost between $720 million to $750 million, Muni officials said the contract can be carried out without going over the $1.6 billion overall budget for the project.
However, the contingency fund for the Central Subway project has dwindled from $200 million to $70 million and there are still six years left of construction work.
The Central Subway project will extend Muni’s underground T-Third Street service by 1.7 miles, connecting South of Market to Chinatown.
