Value Delivered

We provided expert design-build mechanical, electrical, and plumbing (MEP) services, as well as integration and controls for this new integrated central plant, cogeneration facility, and data center. 

Our team worked tirelessly to furnish, install, and commission the latest in redundant cooling and power systems, helping ensure the facilities were up and running as soon as possible with the finest equipment. 

Client Objectives

Qualcomm needed an experienced design-build contractor with expertise in the cutting-edge MEP equipment found in data-center environments.


We provided MEP solutions for all three of the integrated facilities.

The central plant includes:

  • Four 700-ton centrifugal chillers
  • Four 700-ton cooling towers
  • 13 chilled and condenser water pumps
  • Chilled and condenser water piping
  • Ladders, walkways, and platforms
  • All necessary motor control centers

The cogeneration facility consists of a 4.5-megawatt combustion turbine generator from Solar Merc. The generator features a 54-inch exhaust line and diverter valve that sends 700-degree exhaust gas to a broad absorption chiller tied into the chilled water system.

The data center covers 2,500 square feet of white space with a total server load capacity of 1.8 megawatts. Its redundant systems include: 

  • Backup power from three diesel generators, two at two-megawatt and one at 500-kilowatt 
  • A battery backup uninterruptable power supply 
  • Two 400-ton air cool chillers serving as backup and trim chillers 
  • Boiler plant with four 2-million-British-thermal-unit condensing boilers with required pumps
