SCOPE OF WORK

Our scope of work included project phasing to insure that they building remained 100% operational during the construction process.

Engineering design for replacement and upgrade for the building chilled water system which included replacement of two (2) chillers with new 750-Ton chillers, upgrade of piping distribution systems.  Upgrades for chiller plant systems will include stand-by make-up water system for cooling tower in the event of loss of water supply system to building.

System design for adding a 4th generator plant located on the 1st floor.  Design includes upgrades to fueling systems, alarm, and power systems.  Upgrades included modifications to SCADA systems for the 4th generator and integration into new paralleling gear.

Addition of new HVAC cooling system to support the 5th Floor Data Center.  Systems included new HVAC iar handling systems and in-row cooling.  Eqiupment is located on the 4th Floor and ducted and piping up through the ceiling structure of the 4th floor to the raised floor on the 5th floor.

Upgrade fire smoke and depression systems.  Sprinkler systems were installed in common areas on the 4th & 5th floors.  Sprinkler systems are dry-pipe double action and infrastructure will include new compressed air or nitrogen systems sized to serve the facility based on requirements for the COH high riser building codes.

Ventilation upgrades for the building were included in this project. Scope of work includes designing and installing a new make-up air handling system located in the penthouse and modifying the ventilation air serving the chiller room to provide make-up air for the generator room.
