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.
