Due to the scale and schedule of this project, TiePoint-bkm has been retained to provide on-site QA/QC, Level 2 (installation verification and testing validation), and L3 (pre-functional) commissioning before handing off the L4 (functional testing) and L5 (integrated systems testing) to another commissioning provider. To accomplish this task, TiePoint-bkm has four full-time personnel on site for a continuous 12-month period.
Electrical Infrastructure: This portion of the campus is supported by a new 150 MVA HV Substation (160kV – 27kV). Each data center building is equipped with four 1,200A 27kV / 416V Site Distribution Centers, which in turn support a total of 24 Critical Power Distribution Centers (each sized for 4000A at 416Y/240V). The PDCs (12 per floor) feed a series of overhead 2000A busways serving the IT cabinets. Each PDC is backed up by a dedicated 2.75 MW Engine-Generator (24 in total).
Mechanical Infrastructure: The three 60 MW data center buildings will be supported from a central Chiller Plant designed for 12-2,000 ton line-ups (chiller, cooling tower, HX, pumps, electrical SWGR, and 2 MW Engine Generator) connected to a common 36” header, with dual-path distribution extending overhead throughout the campus. Under this phase, only 6 of the line-ups were installed in the Chiller Plant. Each data center building has a pair of 16” cross mains, supporting a looped network of piping on each floor. Custom overhead fan coil units provide critical cooling throughout each cold aisle (approximately 270 units in total).
