Los Angeles, CA
Lane Building, 8th and Spring Streets
Scope/Solutions
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.
As the executive structural engineer for the seismic retrofit, SGH applied ASCE 41 to design structural strengthening that complied with the City of Los Angeles’s Non-Ductile Concrete Retrofit Program. Highlights of our work include the following:
- Evaluated the existing building structure
- Performed advanced performance-based nonlinear analyses, including soil-structure-interaction evaluations, which allowed us to optimize the design and save construction costs
- Designed the seismic upgrades, including new concrete shear walls and concrete moment frames, and strengthening with carbon fiber composites
- Participated in a third-party peer review process through which our analysis and design was reviewed by another structural engineer

Fulton Market
The developer wanted to build a mixed-use property in San Francisco’s Pan Handle neighborhood. The five buildings consist of three wood-framed residential levels on a concrete podium with ground-level commercial space. SGH assisted the project architects with the design of the building enclosure.

Crossing 900
Adjacent to the Redwood City Caltrain station, Crossing 900 includes two mid-rise office buildings sharing a landscaped podium over retail space and below-grade parking. SGH was the designer of record for roofing and waterproofing systems.
