Sentinel Data Centers needed to convert their existing 220,000-square-foot warehouse into a multi-tenant Tier 3 data center facility. AECOM worked with Sentinel throughout 2011 and 2012, providing construction management services over a three-phase delivery. When Sentinel decided to pursue LEED Gold certification for the project, AECOM helped them to meet their sustainability targets.

Phase I: Four 10,000-square-foot data pods

  • Construction of expanded infrastructure, including a new 69 kilovolts substation, outdoor modular chiller plants, four 2,500 kilowatts emergency generators, three UPS (uninterruptible power supply) systems, and associated switchgear.
  • Two 25,000 gallon underground fuel oil tanks and associated fuel oil piping to tie into the generators.
  • Pod cooling provided by 32 Liebert 50-ton CRAC (Computer room air conditioning) units and UPS rooms serviced by three 30‑ton CRAC units.
  • Build-out of 10,000-square-foot of office space and storage
