Vision on Wilshire

SGH assisted with the design of below- and at-grade waterproofing; exterior wall cladding; windows; podium, terrace, and balcony waterproofing; 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 sections of the project specifications, including criteria for building enclosure performance and requirements for mockups and testing certain systems

• Collaborated with the project team to evaluate the use of window walls, considering schedule and cost advantages

• Developed details to integrate the various systems, such as podium and balcony waterproofing with the exterior wall systems; concrete planter waterproofing with the window wall system; pool/jacuzzi waterproofing with the other systems at the roof deck; and the ground-level, fluid-applied air barrier and storefront system with the window wall system above

• Helped develop alternate window wall details and transitions to decrease the risk of water intrusion and increase thermal/energy performance

• Coordinated installation of a hot rubberized-asphalt podium waterproofing system to remain continuous through planters, pedestal pavers, and other amenity features

• Provided construction administration services, including reviewing contractor submittals, visiting the site to observe installation of the building enclosure assemblies, and helping the project team address field conditions
