H2M provided complete engineering services from investigation through construction for the upgrades to the chilled water plant at the USPS Bronx General Mail Facility. This project included the installation of the following:
- Three 250-ton centrifugal chillers
- One roof mounted, three cell cooling tower
- Condenser water pumps
- Primary and secondary chilled water pumps
- Piping and associated valves and expansions tanks
- Glycol feed system
- Chemical feed system
- Complete DDC controls with graphical end user interface
- Refrigerant monitoring system
- New motor control centers and starters
- New chiller room floor drains, piping, and sump pumps
All work, including demolition and new construction, was performed during the off season to insure the new system would be complete and operational by May 2005. H2M worked closely with the USPS and the contractor to minimize any impact on the existing operations of the building.
