Blue Cross Blue Shield of Massachusetts Innovation Center, 101 Huntington Avenue


Blue Cross Blue Shield of Massachusetts (BCBSMA) wanted their Innovation Center to reflect their mission for helping patients attain quality health care and undertook renovations to enliven their three floors at 101 Huntington Avenue in Boston’s Back Bay. SGH provided structural engineering and building enclosure engineering services to help BCBSMA achieve their vision for a dynamic workspace with a vibrant two-story atrium and roof deck.

SGH designed modifications to the existing structure and building enclosure along with new components to help the project team create a two-story atrium by removing 600 sq ft of the third floor slab and the rooftop amenity deck on a previously unused roof area. Highlights of our work include:

  • Designing the new elevated roof deck platform, the structural steel cabana, new railings, and associated strengthening of the existing base building structure
  • Consulting on repairs to the roofing membrane around structural penetrations for the amenity structures and the new opening in the existing curtain wall to provide access to the deck
  • Creating a two-story atrium adjacent to the roof deck, which required strengthening one of the building’s columns to span the two-story atrium while also supporting twenty-two stories above
  • Collaborating with the contractor on the design of a feature stair in the atrium
  • Designing a three-story shaft in the existing structure and a new pit hung from the first floor to accommodate an elevator connecting BCBS’s spaces
  • Supporting the feature storefront entrance from the ground level
  • Designing additional structural support for miscellaneous features, such as operable partitions and handrails
