The challenge 

In 2001, as NewYork-Presbyterian Hospital (NYPH) was preparing to install a new 120,000-lb/hr boiler and auxiliaries at its Columbia Medical Center boiler plant, the hospital needed to solve a problem: how to rig the new boiler, specified by another consultant, into the boiler room with its very limited access space. The hospital's chilled-water system operations and distribution were also in need of optimization at the time to increase capacity and correct flow problems. NYPH called on WM Group to tackle both these challenges.

The smart solution 

After the other consultant had specified a field-erected boiler, WM Group developed a smart solution for NYPH involving a packaged boiler, which ultimately reduced construction costs. The firm also studied the chilled-water plant system serving Columbia Medical Center using a hydraulic model and created an optimization plan that reconfigured the system to an all primary pumping system - further adding to the plant's cost savings.
