SGH assisted HKS Architects, the architect of record, with the building enclosure design, including waterproofing, exterior wall and glazing systems, and roofing. Highlights of our work include the following:

• Reviewing the building enclosure design for airtightness, watertightness, thermal performance, condensation resistance, and constructability, and recommending ways to improve performance

• Assisting with the design of roofing and below-grade, plaza, and terrace waterproofing by helping select systems and developing details to integrate the various waterproofing assemblies with each other and with other building enclosure systems

• Helping detail ribbon windows and brick veneer cladding and their transitions for the low-rise buildings

• Consulting on the tower’s curtain wall assembly, including developing a performance-based specification, helping the owner select a manufacturer, reviewing performance mockup shop drawings, collaborating with the manufacturer to help them modify certain elements to improve durability, visiting the plant to review the fabrication process for the performance mockup units, witnessing assembly and testing of the performance mockup

• Providing construction phase services, including reviewing cladding and waterproofing shop drawings, observing ongoing construction, and witnessing field testing, and helping the contractor address field conditions
