BART Seismic Retrofit Design – “A” Line North Oakland and San Leandro, CA

The BART Earthquake Safety Program is committed to providing a safe, operational BART system by implementing quality seismic retrofits and using innovative solutions that meets cost and schedule requirements. The main objective of this project was to provide final plans and construction documents for the seismic retrofit design of the “A” Line North segment of the BART system’s original aerial guideway structures. The project extends from 22nd Avenue in Oakland to Marina Boulevard in San Leandro.

CHS Consulting Group developed construction staging plans and final contract drawings, specifications, and estimates for the entire project alignment from Oakland to San Leandro.  The final plans were prepared with the approval of the Cities of Oakland and San Leandro, including modifications for 14 intersections along East 12th Street/San Leandro Street. Many of these locations are intersections with State Routes and major arterials, so the level of coordination involved Caltrans and the County of Alameda. To achieve the desired results, CHS focused on major issues such as minimizing impacts to current traffic operations, and to businesses and residents within impacted areas.
