Phase I of retrofitting an existing warehouse to a state-of-the-art data center for an undisclosed client. An expedited six (6) month construction schedule was established and achieved from NTP to certificate of occupancy. Infrastructure was installed for future expansion to ultimately house over 11,000 tons of cooling. The existing concrete slab was removed for below-grade plumbing and electrical services. A new city water tap was installed to provide redundant water sources for the facility. A field-erected 60,000-gallon steel thermal energy storage tank served dual purposes: (1) a backup cooling water source as well as a (2) a backup HVAC make-up water source. An extensive third-party commissioning process was utilized to ensure every aspect of the design was functioning properly. Floor-anchored structural steel was installed to support the new utilities (i.e., piping, ductwork, electrical, sprinkler, etc.) that structurally could not be supported by the existing joist system.

The project is implemented in an existing warehouse-type facility. The administrative space consists of AT&T and customer offices, conference rooms, lounges and customer work stations.
The web hosting floor area was installed on a 30” high raised floor to allow clear access to the web hosting area for all customers.
The building mechanical systems were de-signed and implemented to support the customer equipment, building switch gear rooms, UPS switchboard rooms, battery rooms, mechanical and emergency generators switchgear rooms and central administrative offices core.
As per design, the implementation of the project was scheduled to be done in three phases.
Phase I entailed the following scope of work:

Hewlett Packard’s Site 5 Data Center location was an existing 359,500 square foot building. The building when 100% complete will contain five (5) data processing cells, front office space, rack storage areas, and server building areas. Our scope of work included building out two (2) data processing cells, front office area, and one (1) Rack Storage area and Server Building Area. Space for the remaining three (3) data processing cells is presently and unfinished area.
Each data processing cell had its own independent mechanical and electrical system. Each data processing cell was served with chilled water by a 10” chilled water piping loop. The chilled water loop piping served twenty six (26) downflow computer room air conditioning units that discharge cool air under the Server Room raised floor. The chilled water loop also provided chilled water to eleven (11) upflow computer room air conditioning units that cooled the various electrical rooms. Two air-handling units (one primary and one redundant) and associated VAV boxes were used to do the central cooling for the electrical rooms and corridors. Three (3) 500-ton air-cooled chillers serve the 10” chilled water piping loop. Each Server Room was also cooled by an independent 40-ton air-cooled chiller, chilled water pump, and air-handling units. This independent chilled water system was used to dehumidify the makeup air to the Data Processing Area. Various fans also were incorporated into each data processing cell. A water leak detection system was installed under the raised floor of each cell to provide an alarm should water be present under the Computer Room Air Conditioning Unit Galleries.
Cell #1 and Cell #2 were provided with 8” cross-connect chilled water piping in case of an emergency. The small data processing air-handling units could also be served by chilled water from the main chilled water loop.
The Front Office Area, Rack Storage, and Server Building Areas were cooled by self-contained Rooftop Units. The supply air from these units is distributed throughout these spaces by VAV’s and PIU’s. Each RTU had its own dedicated electric duct heater and duct-mounted humidification system. IT rooms in the Front Office Areas were also cooled by independent DX computer room air-handling units and condensing units.
Control work on this project was done under a separate contract with the owner.

Installation of HVAC, Plumbing, & Fuel Oil Systems for a Confidential Data Center. Precast structure consisting of two levels. Aggressive schedule implemented to meet the customers’ needs and requirements.
Due to the aggressive scheduling nature, (2) consecutive shifts were provided and managed. Heavy coordination with other trades was required to schedule, install, test, and start up the systems.
