Project Summary

Scope/Solutions

Adjacent to the city’s new central library and just blocks away from Petco Park, K1 at 330 13th Street offers residents a variety of community areas for gathering and relaxing. The building includes 222 apartment units, ground-level retail space, a podium-level amenity deck with a pool, and below- and above-grade parking. The twenty-three-story building features private balconies and floor-to-ceiling window walls alternating with opaque panels. SGH consulted on the building enclosure design.

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
