Earthquake Resistant Tower in San Francisco to Become Most Resilient Tall Building on West Coast

Soaring high above! #SanFrancisco #RealEstate #181Fremont #LEED #tech #office

181 Fremont—which will become the third tallest structure in San Francisco and the most resilient tall building on the West Coast of the U.S.—has been awarded the REDi™ Gold Rating, a new earthquake resilience rating. The building was designed by San Francisco-based Heller Manus Architects.

The 56-story mixed-use tower, built above five basement levels, is being constructed in compliance with a new set of holistic design and planning guidelines—the Resilience-based Earthquake Design Initiative (REDi Rating System)—that allow it to withstand the impact of a 475-year seismic event (roughly a M7.5-M8.0 earthquake on the San Andreas Fault) with minimal disruption.

Developed by Arup with contributions from external collaborators, the REDi™ system outlines design and planning criteria within a resilience-based framework, creating a system that not only considers occupant safety but also takes into account the future of the building after an earthquake.
