This project was part of the overall $2.5-billion San Francisco International Airport’s Master Plan.
Client: San Francisco International Airport
Location: San Mateo County, CA
This portion of new facilities involved construction of two eight-story garages connected by a bridge, an approximately 2500 feet elevated structure for BART and AirTrain lines, a BART station, and a six-story rental car facility at the San Francisco International Airport between the new International Terminal and US Highway 101. The overcrossing BART structure runs adjacent to the freeway and then overcrosses at US Highway 101.
As a prime consultant, AGS performed geotechnical investigations, and developed site-specific geotechnical and seismic design criteria to Caltrans standards for the above structures.
The firm provided geotechnical and earthquake engineering services for design of the pile-supported buildings. The firm performed field exploration, laboratory testing, and engineering analysis; developed seismic response spectra and other seismic design parameters; and prepared a geotechnical investigation/earthquake report. The field exploration program included drilling 28 borings, performing field vane testing, performing pressure meter testing and cone penetration testing, and conducting downhole geophysics testing in two borings. AGS also had a significant role in geotechnical construction monitoring of the projects.
