Beth Israel Deaconess Medical Center, Inpatient Building

As the structural engineer of record, we designed foundations and the steel-framed superstructure for the New Inpatient Building. Highlights of our design include:

• A 60 ft cantilever over the existing emergency department building springing from a 90 ft column-free backspan over an ambulance bay
• Slurry wall and load-bearing elements that serves as the building foundation, support of excavation, and lateral support for foundations at adjacent buildings
• Links to the Rosenberg Building and a two-level bridge connecting to an existing bridge crossing Pilgrim Road
• An interstitial mechanical level added to Level 4 of the Rosenberg Building

SGH consulted on the design and helped select systems for below-grade and plaza waterproofing, exterior wall assemblies with terra cotta and composite metal wall panels, unitized and stick-built curtain walls, and roofing. Highlights of our work include:

• Collaborating with the architect, owner, and contractor during the design-assist process for the unitized aluminum-framed curtain wall and terra cotta wall assemblies
• Consulting on expansion joints between the new and existing buildings
• Visiting the unitized curtain wall factory to observe fabrication processes
• Witnessing water testing of the curtain wall assemblies and quality control testing of other systems, such as roofing and plaza waterproofing
• Serving as the building enclosure commissioning (BECx) agent to establish performance expectations and develop the BECx plan, outlining the commissioning requirements
