Flatiron and its joint venture partners raise the Calaveras Dam Replacement Project to its full height

Broomfield, Colorado (September 21, 2018) – Flatiron, together with Joint Venture partners Dragados USA and Sukut Construction, joined the San Francisco Public Utilities Commission (SFPUC), the California Department of Water Resources Division of Safety of Dams and the Bay Area Water Supply and Conservation Agency in announcing that the Calaveras Reservoir reached its full height, marking a major milestone in the Calaveras Dam Replacement Project.

The project, originally valued at approximately $259 million, replaces the original dam, built in 1925, with a new 210-foot-high earth and rock fill dam designed to accommodate earthquakes on the Calaveras Fault. Construction included a new 1,550-foot-long spillway utilizing 40,000-cubic-yards of concrete, construction of a new intake/outlet tower consisting of a 20-foot-diameter by the 163-foot-deep vertical shaft and three new tunnels to convey water to and from the reservoir.

Crews still need to construct access roads, automate instrumentation and controls, restore the site, and place rock slope protection before the overall project is complete, which is slated to wrap up in the spring of 2019.
