San Francisco, CA
288 Pacific
Scope/Solutions
Just one block from the Jackson Square Historic District, 288 Pacific incorporates modern residences with an early 1900s masonry structure. The project brings thirty-three condominiums to the neighborhood in a seven-story, L-shaped structure surrounding the Old Ship Saloon. The building’s stepped elevations create spaces for private terraces and more windows. The masonry facade with tall windows blends with the neighborhood’s historic character. SGH consulted on the building enclosure design.
SGH consulted on the design of the building’s below-grade and terrace waterproofing, exterior wall cladding, windows and doors, window walls and storefronts, and low-slope roofing. Highlights of our work include the following:
- Helped select roofing, waterproofing, and wall cladding systems, taking into account the project team’s design vision and performance expectations
- Reviewed the building enclosure design, identified opportunities to improve performance, and evaluated substitutions
- Prepared technical specifications for the waterproofing systems
- Developed details to integrate the various systems and coordinated below-grade waterproofing and expansion joints with existing adjacent construction
- Specified and witnessed a mulitistory exterior cladding and window laboratory mockup for evaluating performance, coordinating installation sequencing, and confirming tolerances and constructability
- Provided construction-phase services, including reviewing contractor submittals, providing isometric sketches and cladding models to help the installers, performing below-grade waterproofing warranty inspections, observing ongoing construction and field performance testing of cladding and fenestrations, and helping address field conditions

Bellevue-Staten Condominiums
The Bellevue-Staten building was constructed in the 1920s in the Art Deco style and is on the National Register of Historic Places. SGH investigated the condition of three chimneys and developed a retrofit to address the deficiencies.

Lane Building, 8th and Spring Streets
The historic Lane Building is a twelve-story, nonductile concrete structure originally constructed in the early 1920s. The owner undertook a renovation project to convert the building to a mixed-use property with ground-floor retail and more than 100 apartment units. SGH collaborated with the project team to design seismic strengthening that could be integrated with the proposed program, while maintaining the building’s historic character.
