Flatiron Construction Corp. (FLATIRON) together with its joint venture partners, Dragados USA and Sukut Construction LLC, was awarded the contract to modify the Lake Isabella Dam in Kern County, CA, by the U.S. Army Corps of Engineers, Sacramento District.
The Lake Isabella Dam Safety Modification Project, valued at approximately $242 million, includes raising the earthen main dam, auxiliary dam and main dam control tower, reconstructing the existing spillway to improve stability, and adding an emergency spillway.
The project is expected to improve public safety and reduce flood risk from dam failure to downstream communities. The improvements will also minimize the potential of dam overtopping by raising the crest and constructing the emergency spillway. Construction activity is expected to begin in October 2017 and conclude in the spring of 2021.
