JDP served as the base-building HVAC contractor for the gut-rehab of JPMorgan Chase's global headquarters.

This was a multi-phase four-year project included the design, fabrication, and replacement of all major HVAC equipment and systems.

In order to allow the building to remain occupied during this major construction, we installed a supplemental chiller plant.

Innovative planning and coordination allowed JDP to bring the chillers to the site via the Metro North rail lines – chillers were loaded onto trains at New Rochelle and offloaded adjacent to the basement and brought into the building.

All major systems were replaced – primary air handlers, exhaust fans, primary chilled water pumps, and condenser water pumps.

Plate-frame heat changers were installed for the condenser water and cooling tower water. Additionally, pressure-break heat exchangers were installed at several levels.

Upon completion of all the new equipment and BMS, the building was awarded LEED Platinum certification.
