San Francisco Public Utilities Commission has awarded a US$259 million contract to a joint venture of Dragados USA, Hochtief group Flatiron and Sukut Construction for replacement of Calaveras Dam in California.
The split of the work on the Calaveras Dam will be 40 percent Dragados, 30 percent Flatiron and 30 percent Sukut Construction.
The new dam will be constructed immediately downstream of the existing dam. Project completion is anticipated in late 2015. The project includes replacement of the original dam with a new 64-meter-high earth and rock fill dam. There will also be a new concrete spillway.
