JE Dunn constructed DST’s Winchester Data Center, which contains over 70,000 SF of white space with 2N infrastructure redundancy. This existing Tier IV facility was fully occupied and remained in service throughout construction. The overall scope encompassed upgrades to the existing mechanical infrastructure and complete replacement of the power distribution system. Mechanical and electrical upgrades were phased and sequenced as to not affect current day-to-day operations of the facility.
The electrical system upgrades included the complete replacement of the existing generator plant and main switchgear. Mechanical upgrades included modifications to existing equipment and additional chilled water distribution piping necessary to eliminate single points of failure. Oversized distribution piping improved efficiencies as well as accommodated for future equipment layouts on the white space.
HVAC controls upgrades encompass the entire facility. Design and installation of DDC control systems were required to properly manage the renovated chilled water plants including chillers, pumps, cooling towers, and heat exchangers. Complete replacement of controllers and instrumentation for all back of house and white space HVAC systems were provided as well.
