Program and Design:  Replaced existing underground utilities with a new, nine foot diameter underground utility tunnel. Using a Tunnel Boring Machine the utility tunnel was installed 40 feet below grade. This design approach minimized environmental disturbance and maintained uninterrupted utility services to existing buildings. Daily operations and traffic circulation were also undisturbed during construction. The tunnel is 2,000 feet long and provides for convenient installation of future utilities and technologies.

General Contractor: Pavarini Construction Co.


Program and Design:  To support large Data Center operations, new free-standing hardened sub-station building was constructed on the site with dual 4,000-amp services each from a separate utility company feeder. An addition to the building was designed to accommodate four 1,000 kw emergency generators with paralleling gear. Four 750 KVA UPS systems were designed, each in an isolated room, to achieve an N+2 design. A Data Center cooling system was provided with high-density rack-mounted cooling units.
