Mass State Lab - HVAC Improvements


The Massachusetts State Public Health Laboratory is an 8-story concrete building on the UMass Medical School - Jamaica Plain Campus, which handles several time-sensitive and mission-critical biological and chemical testing functions for the state.

DCAMM contracted W.T. Rich to execute the facility's emergency HVAC improvements project. The scope consisted of the complete replacement of the facility's chiller plant, including three new 600-ton chillers, two 600-ton cooling towers, and associated mechanical pumps and VFD's. The work included replacing three 65,000 CFM supply fans and replacing 115 VAV boxes serving highly sensitive laboratory operations. The work also included the installation of two new roof-top exhaust air handling units and a new temperature control building management system.
