SGH consulted on the design of below-grade and at-grade waterproofing, podium and balcony waterproofing, exterior wall and glazing assemblies, and low-slope roofing. Highlights of our work include the following:

• Reviewed the proposed design, helped select systems, and suggested ways to improve performance

• Prepared design performance criteria and recommended a scope for mockups and testing included in the project specifications

• Developed details to integrate the various assemblies, such as exterior wall systems (e.g., window wall glazing, metal panel rainscreen, cement plaster, and glass fiber-reinforced concrete wall panels) and their intersections with below-grade, podium, and balcony waterproofing

• Collaborated with the project team to detail an alternate air barrier assembly following a mid-project change in the rainscreen design and to maintain enclosure continuity and system separation at locations where incompatible exterior wall systems intersect

• Helped identify and clarify podium waterproofing installation requirements and helped coordinate membrane transitions and terminations at the podium perimeter and at the spa/pool areas

• Witnessed performance testing of installed window assemblies

• Provided construction administration services, including reviewing contractor submittals, visiting the site to observe ongoing construction, and helping the contractor resolve field conditions
