Working with Elkus Manfredi Architects, SGH assisted with the building enclosure design.  We reviewed design concepts and provided recommendations to improve system performance.  Highlights of our work include the following:

• Recommending below-grade waterproofing system that would provide the necessary reliability for a blindside application and included safeguards during the sheet pile disassembly

• Assisting with the selection of a buried plaza waterproofing system, detailing transitions into the rising towers, and accounting for drainage under plantings and hardscapes

• Consulting on metal and glass curtain walls, punched windows, terra-cotta, and metal wall panels, and prefabricated unitized wall panels

• Designing transition details across all enclosure systems, including special detailing for chemical compatibility of transitions

SGH provided construction administration services, including the following:

• Reviewing product submittals and shop drawings for all enclosure systems

• Coordinating preconstruction meetings with the contractor and various building enclosure related subcontractors

• Conducting field adhesion testing of the air barrier systems and pressure-differential water and air infiltration testing on the curtain walls and punched windows to compare with performance requirements

• Designing and observing electric field vector mapping of the plaza

• Visiting the site to observe in-progress construction to compare with the design intent and approved shop drawings
