181 Fremont in San Francisco has achieved a REDi Gold Rating, which will make it the most resilient tall building on the West Coast of the United States.

The 56-story mixed-use tower is being constructed in compliance with a new set of holistic design and planning guidelines: the Resilience-based Earthquake Design Initiative (REDi Rating System). Developed by Arup and a diverse group of external collaborators, REDi establishes a new benchmark for seismic construction — far exceeding current code criteria — that focuses on quick recovery and continued operations in the aftermath of an earthquake.

We sought to develop a blueprint for designers and owners who wanted to achieve higher resilience targets, with the ultimate intention to promote community resilience. This aligns with Arup’s mission to shape a better world. ” Ibbi Almufti Ibbi Almufti Principal

For 181 Fremont, Arup served as the structural engineer, geotechnical engineer, and resilience consultant on the project, shepherding the design team through the resilience-based design process. The owners and designers pursued a REDi Gold Rating which included enhanced structural and non-structural design to limit damage, improve egress systems and contingency plans, and reduce post-earthquake recovery times to keep their space earthquake ready.

Projects like this are great to show the value in thinking about what it means for buildings to have their own post-disaster continuity in place, which helps expedite and contribute to a speedy recovery for the larger city. ” Patrick Otellini Chief Resilience Officer for the City and County of San Francisco
