Emcor Group subsidiary J.C. Higgins has been awarded a contract to install the mechanical systems at the Children’s Hospital Boston.

J.C. Higgins will be responsible for installing the HVAC, plumbing and fire protection systems in the 100,000-square-foot addition to the hospital’s main building. The addition will consist of 10 new stories, with a two-level penthouse and two levels below ground. The addition will permit increased patient beds, expansion of the emergency department, increased radiology capacity, additions to surgical areas, and new in-patient support spaces.

“Children’s Hospital Boston is one of the oldest and most respected pediatric medical centers in the U.S., and it’s extremely gratifying to be able to increase the comfort and safety of the hospital’s patients, and the doctors and staff who help them, through the work we perform in creating precise, systems-rich environments,” said Ron Ledoux, president and CEO of J.C. Higgins.

The HVAC work will include installation of a new heating system and a 20,000-gallon fuel oil tank serving the emergency generators, and installation of an additional 1,000-ton chilled water plant in the penthouse mechanical room as a backup to the main system.

Plumbing scope of work will include performing major infrastructure upgrades to the building, such as installing a new domestic water booster system and heating plant, lower level ejector pumps, new medical vacuum equipment, and a pre-treatment water system including a chlorine-injection system. The fire protection work will include designing and installing fire sprinkler systems throughout the entire 100,000-square-foot addition, and minor renovations to the existing system.
