Casa Adelante, 1296 Shotwell

Resilient Design


Casa Adelante is a 9-story affordable housing for seniors located in San Francisco’s Mission neighborhood. The developer MEDA and co-developer Chinatown Community Development Center hired Mar Structural Design to design the building for structural resilience.


The engineers at Mar used SP3-Design (now SP3-Advanced) to achieve a Gold USRC score by using rocking RC walls with dampers; in doing so, there where able to reduce expected losses down to <10% for design-level shaking, and this resilient design only cost $100k (0.24% of construction cost).
