The BART-SFO project is a 7.5-mile-long design-build twin-rail trackways project with approximately 6 miles of subway and 1.5 miles of at-grade trackway, four aerial structures with lengths ranging from 1,500 feet to 2,200 feet, two stations, several thousand feet of retaining walls, and miscellaneous buildings. The estimated cost for the entire project is $530 million.
EMI provided services including reviewing available geotechnical information, performing field investigation and conducting engineering analyses and report preparation. Major geotechnical issues on the project included high seismic shaking, soft Young Bay Mud, liquefiable soils, and large-diameter drilled shaft foundations for the aerial structures.
EMI provided foundation recommendations, liquefiable and soft-soil evaluation, earth pressures, slope stability, foundation stiffness, and seismic design of the structures.
