350 Water Street
Scope/Solutions
Cambridge Crossing is a forty-three-acre, mixed-use development adjacent to Kendall Square and served by the new MBTA Green Line extension. The new building on Parcel G at 350 Water Street houses twelve levels for life science office and laboratory space. SGH consulted on the building enclosure design for 350 Water Street and the building on Parcel H at 450 Water Street that serve together as a flagship campus location for Sanofi.
SGH collaborated with the project team on the building enclosure design, bidding and design-assist process, and construction. Highlights of our work include:
- Consulting on below-grade and podium waterproofing; facade systems, including custom unitized curtain wall systems with integrated sunshades louvers, precast concrete cladding; and roofing systems
- Participating in the curtain wall design-assist process and visiting the fabricator’s plant to observe construction quality control processes
- Consulting on a performance mockup of the custom curtain walls and witnessing testing at an off-site laboratory
- Developing three-dimensional details for complex intersections, such as those where roofing and waterproofing assemblies meet precast concrete panels and curtain walls
- Creating three-dimensional computational fluid dynamics models to analyze the building enclosure performance under high humidity conditions required by the tenant and condensation potential
- Providing construction phase services, including reviewing contractor submittals, visiting the site to observe ongoing construction, and helping address field conditions
- Helping detail and perform quality reviews of below-grade waterproofing installation
- Performing air/water infiltration testing of the curtain walls and infrared thermal surveys of the completed enclosure to qualitatively evaluate potential air leakage and identify wet materials in the installed roofing assemblies
