Building Hyperscale Data Centers in Silicon Valley
Vantage Data Centers CA3 Project | Santa Clara, California
Vantage Data Centers CA3 is a four‑story, 486,000‑sq.-ft. hyperscale data center located on nearly eight acres in Santa Clara, California. The project is Vantage’s third data center campus in Silicon Valley and is located within two miles of the company’s CA1 and CA2 facilities and near the Norman Y. Mineta San Jose International Airport.

Facility Scope
Designed as a single‑building campus, CA3 provides more than 64MW of critical IT capacity. Vantage’s three Silicon Valley campuses total 216MW of IT capacity. The facility is powered by Silicon Valley Power using 100% renewable energy and opened to customers in October 2024.
CA3 was delivered as a mission‑critical data center with N+1 redundancy across all electrical systems, including an onsite substation and a 400V electrical configuration. Multiple, diverse utility feeds support operational reliability.
The mechanical system includes a closed‑loop chilled water design with air‑cooled chillers and integrated economizers to reduce energy demand during favorable weather conditions. The facility is designed with N+2 redundancy across mechanical systems. CRAH units are located in galleries on opposite sides of each data module to support airflow distribution. The cooling system achieves near‑zero Water Utilization Efficiency (WUE).
The campus also includes dedicated customer office space, conference rooms, secure storage areas and operational support spaces, along with electric vehicle charging stations.

Structural Design Assist
GPLA supported CA3 Phase 1 in a design‑assist role alongside the structural engineer of record, Peoples Associates Structural Engineers (PASE). The project required complex structural framing and foundation systems due to the building scale and seismic conditions of the site.
GPLA delivered LOD 400 fabrication‑level modeling to coordinate prefabricated foundations and reinforcing steel. All reinforcing steel was modeled and coordinated prior to construction, improving constructability and reducing field conflicts. The team designed prefabricated rebar cages for steel grade beams and developed alternative rebar lapping solutions using HRC 555 T-headed reinforcing bars, reducing the overall quantity of reinforcing steel required while maintaining structural performance.
