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
