Corporate Data Center

Location Withheld

This four-story, 135,000-square-foot data center was designed to reliably support the client’s immense data needs. The outdoor equipment yards houses ten 2MW generators, a 250,000-gallon chilled water storage tank, and a hydro-pneumatic well tank (for back-up cooling tower make-up water).

Floors one and two encompass all of the building’s infrastructure (switchgear, UPS, batteries, chillers, and pump rooms), while the two upper floors are completely dedicated to raised floor computing space. Phase 3 and 4 consisted of fitting out the 35,000-square-foot third floor for computing space, and completing the necessary infrastructure (incorporating two 600-ton chillers and associated towers, pumps, piping, controls, etc.)

The data center was designed for a Tier IV rating as defined by The Uptime Institute (fault tolerant/concurrently maintainable). The chilled water plant consists of six 600-ton chillers in an N2 arranegment. The plant was equipped for 3,600 tons of capacity to serve the 2,400-ton demand. The chillers were compartmentalized into three rooms with two chillers each. As such, an outage in one room would not affect the plant’s capacity to maintain the load. An outdoor thermal storage tank (135,000 gallons) was provided for continuous cooling.

Additionally to ensure that the installed systems fully complied with the design intent, BKM fully participated in the factory witness testing of the chillers and CRAH units, as well as weekly construction progress meetings and monthly site inspections. As the project neared completion, BKM assisted with commissioning, including site acceptance testing (verifying each piece of equipment was installed properly; factory start-up was performed, and the controls are working properly). This testing was followed by the integrated testing (3,400 kW of load banks were brought onto the floor to simulate the cooling demand, and the building’s performance was fully verified). The integrated testing also included simulation of various failure modes to ensure the system’s reliability.
