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
