Throwback Thursday: North Shore Outpatient Center

Updated: Sep 16

Celebrating 60 Years


In honor of celebrating 60 years, F&T is sharing past projects and clients from over the years. This week’s Throwback Thursday: Mass General / North Shore Outpatient Center in Danvers, Massachusetts! Fitzemeyer & Tocci provided HVAC, plumbing, fire protection and electrical systems for the 122,000-sf ambulatory care center and core/shell for a 78,000-sf medical office building.


The goal of the project was to provide cost-effective HVAC, plumbing, electrical and fire protection systems for a state-of-the-art healthcare facility based upon a retail model of an outpatient healthcare facility. The project was kicked off in 2006 and completed in 2021.



Our Design Solutions

  • Our design solution involved providing heat for the building by a gas fired hot water boiler plant consisting of high efficiency gas fired boilers located in a penthouse mechanical room. Cooling and ventilation are provided by a combination of custom hospital grade (ambulatory care) and large commercial grade packaged roof top units (medical office) which are concealed behind architectural roof screens.


  • A 100% redundant medical equipment chiller system provides process chilled water to MRI’s, Linac’s, and CT scan equipment. A dedicated dry-cooler condenser water system provides cooling to the data center and IDF rooms. A Direct Digital Control Energy Management System controlls the entire system.


  • The electrical system included a new medium-voltage distribution system to serve the 5000 Ampere 480/277V 3Ph 4W electrical service. A 1500kW/1875kVA emergency generator located on the exterior of the building in a sound-attenuated weatherproof enclosure provides emergency power for the building essential electrical system. The essential electrical system provides life safety, critical, equipment and elevator power for the ACC and life safety power for the MOB.


  • The plumbing design included new sanitary waste, natural gas, hot and cold domestic water and medical gas and vacuum systems. The fire protection design included new wet pipe sprinkler and standpipe system throughout both buildings. Several critical areas such as the MRI, the Linear Accelerators and Data Center were treated with a double preaction dry pipe sprinkler system.
