QTS Metro Data Center

The Quality Technology Services Data Center is a 990,000-square-foot facility and is the second largest data center in the U.S. The facility provides mission critical electrical, mechanical, and high capacity network systems. When build-out of the facility is completed, the building will yield approximately 547,000 square feet of Data Center Space. The expansive facility is supported by 80 megawatts of N+1 power capacity (3X40 MW Transformers) via an on-site Georgia Power substation and has 19 two-megawatt diesel generators with static UPS systems to provide over 20MW’s of usable backup power.

JE Dunn was hired to build-out Phases II and III and installed and commissioned the following:

  • Generators {(16) 2.5MW 13.8kV Units}
  • 2 sets of 15kV 1200A rated Paralleling Switchgear
  • Cooling Towers
  • Chillers {(2) 2600 Ton machines}
  • UPS Systems 10.8MW of UPS Capacity}
  • Unit Substations {(8) Sets for a total of 30 MVA}
  • Output Distribution Switchboards {(4) at 3000A 575V Each}
  • Power Distribution Units {(60) 300kVA Units}

JE Dunn has installed 125,000 square feet of 48” tall raised access flooring that will be ultimately built out to 200W/SF. All necessary MEP infrastructure was also installed so that addition of future equipment on the raised floor will have no impact to the Data Center reliability.

In 2017, JE Dunn added on a new front entry, including a security office and conference rooms to the QTS Metro Data Center in Atlanta.
