SAN JOSE, Calif. 4/10/12 (PennWell) -- Black & Veatch has been selected by the Santa Clara Valley Water District for an urgent seismic retrofit program at Anderson Dam.
The US$150 million project will allow the water district to again use Anderson Dam for maximum water supply storage when work is completed in 2018. The reservoir currently operates at 69% capacity.
Black & Veatch says the project was prompted by a 2011 seismic stability evaluation that caused the water district to implement self-imposed restrictions on the dam. The evaluation revealed the dam would be subject to significant damage if a large earthquake were to occur nearby.
As program manager, Black & Veatch is responsible for coordinating a team of local small business subcontractors to oversee the project's planning, permitting, design, construction and improvements.
"Our goal is to minimize community and environmental impacts as well as complete the project in a timely and cost-effective manner," says Jim Watson, Black & Veatch program manager.
The company says the seismic strengthening will most likely consist of partially removing liquefiable materials and buttressing the dam. The project will also verify the adequacy of the spillway, outlet works and existing surveillance systems.
