Scope/Solutions

The approximately 700,000 sq ft development was built in the Yerba Buena Center Redevelopment area and cultural destination. Together, a new forty‑three story tower and the historic ten-story Aronson Building offer 146 condominiums and many amenities, such as a fifth-floor club level and resident programs and services. SGH consulted on the building enclosure design for the project.

The tower features an undulating, stainless steel art screen shrouding a future museum in the podium levels and culminates with rooftop terraces overlooking the city. SGH helped design the tower’s below-grade, podium, balcony, and terrace waterproofing; aluminum-framed curtain wall system with operable windows and granite rainscreens; stone- and metal panel‑clad walls; and roofing. We also consulted on renovations to the 1903 Aronson Building, including replica wood windows and penthouse terraces. Highlights of our work include:

  • Authoring specifications for unitized curtain walls, wood windows, dimensional stone panels, and metal panel rainscreens
  • Establishing a basis of design for roofing and waterproofing, identifying ways to improve performance, developing transition details, and evaluating substitutions
  • Performing thermal analyses of the museum facade to evaluate options for vapor barriers, thermal breaks, and insulation
  • Coordinating roofing, exterior walls, windows, and waterproofing with landscaping, mechanical, window washing, structural, and plumbing systems
  • Detailing window flashing for the Aronson Building’s transitional masonry facade
  • Developing isometric details for complex conditions, such as interfaces between the tower and Aronson Building and for below-grade waterproofing at adjacent structures
  • Consulting on full-scale, laboratory performance mockups for curtain walls and replica windows to evaluate performance, installation sequencing, and constructability
  • Visiting curtain wall factories to observe progress and quality control procedures

Our construction-phase services included reviewing submittals, creating isometric sketches and models to depict installation sequences, observing ongoing construction and performance testing of cladding and fenestration, and helping address field conditions.
