BART Aerial Structures

Seismic Retrofit

The San Francisco Bay Area Rapid Transit (BART) system has initiated a Earthquake Safety Program to upgrade vulnerable portions of the original BART system, completed between 1972 and 1976. Portions of the original system with the highest traffic will be upgraded not only for life safety but also to ensure that they can return to operation shortly after a major earthquake. The estimated duration for design and construction of the entire program is approximately 10 years. The total project budget for the Earthquake Safety Program is $1,307 million (in 2004 dollars). As part of the Daly City Aerial Guideway Seismic Retrofit Design team, SC Solutions is involved in all structural aspects of the seismic retrofit design of this elevated structure.
