Mission critical Structure Tone teams managed the construction of the first high-density data center built for under $5 million/MW with a PUE of 1.08. In two construction phases we created a scalable, 125,000sf facility that includes 75,000sf white space, day-one expandable to 150,000sf.
We participated in the evaluation of six sites for power cost, environmental and climate threats, infrastructure and building incentives. We also evaluated for grading, drainage, retention ponds, parking lot, ring road and site utilities (sewer, water, telecoms).
The completed building is a single-story office/admin complex of pre-engineered insulated metal panels and five data center pods. We installed N+1 (EPS) generators and outdoor switchgear to power the pods. The center is 100 percent air cooled by an outside system using hot/cold aisle separation, air economizer and an array of louvers for air intake and heat rejection. Server fans move the air. The facility has no raised floor. Security measures include perimeter fencing, CCTV, intrusion controls and card access within the buildings.
To minimize costs, we applied value engineering, combining, for example, the electrical infrastructure for the data pods to reduce the pod count from ten to five while maintaining full power requirements and eliminating additional buildings and foundations.
We used BIM for clash detection and coordination, and created a 3D operating model showing objects upwards of two inches in diameter. We coordinated project management among stakeholders in California (owner), New York City (builder) and Seattle, WA, (designer).
Despite upstate New York’s cold winters, we placed this facility online in less than a year from phase I groundbreaking. We completed phase II in less time through efficient coordination of trades and sequencing of work.
