The Santa Clara Valley Water District (Valley Water) has selected GISI Consulting Group company GEI Consultants to provide construction management services for the Anderson Dam Seismic Retrofit Project in California, USA.

Originally built in 1950, the Anderson Dam is the largest reservoir in Valley Water’s service area providing water to the region. In 2011, a seismic stability evaluation indicated that the dam could become unstable during a large magnitude earthquake.

“This project represents a once-in-a-generation opportunity to strengthen critical water infrastructure and enhance public safety for the communities of Santa Clara County,” said Violletta McDaniel, Vice President and Construction Management Practice Leader at GEI.

The retrofit project will include removing most of the existing embankment dam and replacing it with a new dam that meets updated seismic safety standards. GEI will oversee construction of the new dam embankment, spillway, high-level and low-level outlet works, pipeline realignments, and modifications to roadways and recreational facilities. The GEI team includes fellow GISI Consulting Group companies Gafcon, who will provide Labor Relations services, and Hill International, who will provide Construction Inspection services.

“We are excited to have GEI augment our team as we prepare for the construction phase of this critical, multi-year megaproject,” says Ryan McCarter, Deputy Operating Officer for Valley Water.

Once completed, the rebuilt Anderson Dam will enable Valley Water to fully restore reservoir operations, increase public safety, and secure a safe and reliable water supply.
