The expansion created a 660,000 sf addition to the largest medical facility in western Massachusetts. The 7-story building gained an additional 126 beds in the first phase of construction, 30 of which were part of an intensive care unit. Future plans will add 190 beds for a total of 316 inpatient beds in the new building as well as an additional 30 operating rooms to replace the current complement of operating rooms in the hospital. Work in this phase also included six, state-of-the-art, heart and vascular operating rooms and post-surgery recovery spaces, and a central sterile processing facility that will ultimately support the entire OR floor. A green, accessible and landscaped roof area was also part of the program. Key infrastructure completed in this phase included boiler and chiller plants for the building, a dual backup generator facility, electrical substations, acid neutralizing facilities to support lab functions in the existing hospital, design and installation of a flywheel UPS system for key critical power needs and a distributed antennae system. Vanderweil implemented a phased MEP systems design approach to accommodate the phased construction including Master Planning for appropriately timed and sized infrastructure investment.

The project received the Health Facilities Management, 2015 Vista Award for New Construction and Engineering News-Record (ENR) New York 2012 Best Projects Award of Merit.
