Mercy Medical Center, Sister Caritas Cancer Center
Scope/Solutions
With the Sister Caritas Cancer Center, Mercy Medical Center expanded oncology services and consolidated their programs into one comprehensive space. SGH designed the structure for the two-story horizontal expansion.
The approximately 26,000 sq ft addition is adjacent to three existing hospital buildings. Highlights of our structural design include the following:
- Steel-framed structure designed to accommodate a future one-story vertical addition
- Base connections for a feature stair in the main entrance atrium
- New foundations combined with existing to integrate new elevator pit adjacent to existing structure
- Custom foundations to bridge over primary utility lines feeding the campus
- Top-side roof modifications to existing roof to reduce snow drift effects with minimal interior work
- Steel moment frames and cantilevers for large projected bays on upper level

Maine Medical Center Coulombe Family Tower Expansion
The recent expansion of the Coulombe Family Tower includes a two-story, vertical addition to the five-story hospital building that SGH designed in the mid-2000s. Anticipating continued growth, Maine Medical Center (MMC) asked SGH to design the original base structure to accommodate additional stories. When MMC was ready to expand, they considered another impending need and asked the project team if the new addition could support a rooftop heliport. SGH provided building enclosure and structural engineering services for the project, which was completed while the Coulombe Family Tower remained occupied.
Northeast
Maine Medical Center, Bean 2 Addition
With a vertical addition to the second level of the L.L. Bean Building, MMC gained space within their existing hospital footprint. SGH designed the addition’s structure and consulted on the building enclosure.
