Designing a Tier III Data Center for Confidential Microelectronics Manufacturer in Santa Clara, California

A data center control room filled with rows of servers

Glumac, part of the Tetra Tech High Performance Buildings Group, was the lead designer and provided mechanical, electrical, and plumbing (MEP) design services for a new data center facility for a colocation provider in Santa Clara, California


Tetra Tech provided a complete mechanical, electrical, plumbing, and information technology (IT)/low voltage design. The new data center is multi-storied with four 10,000-square foot hall vaults totaling 16 MW of total critical power. This Tier III facility is cooled via rooftop economizing chillers and distributed vault computer room air handlers (CRAHs). High-supply air temperature and close approach cooling coils, coupled with the mild climate, yields a highly efficient cooling system without the need to filter large amounts of outside air. The electrical system utilizes two separate sets of four electrical systems. Each set has a catcher system, for N+1 redundancy and concurrent maintainability. The facility will receive power from an on-site customer-owned 30-megavolt ampere (MVA) utility substation.

Tetra Tech and the entire design team overcame multiple challenges, both internally and externally, including an evolving team and system design challenges, none of which hindered a successful delivery that is moving into Phase 2 ahead of schedule.
