Located on Varian’s Walnut Creek campus and hub for their Northern California operations, the data center included dedicated rooftop-mounted A/C units with N+1 redundancy utilizing process chillers and a pre-action FM-200 fire sprinkler system–the fastest available fire suppression system. The data center is serviced by a 400kW diesel generator, UPS, and 24- hour emergency generator fuel operation.

The 133,600sf phased project accommodated the merging of two independently operating businesses and consisted of voluntary seismic upgrades and various renovations of two existing buildings totaling 89,900sf, as well as a new ground-up, single-story 43,700sf, Type III B, fully-sprinklered facility combining both demonstration labs, R&D labs, office and training space, work rooms, and other admin functions. The project included the demolition of a single-story building and modifications to the existing building while remaining occupied and operational.
