The Oakland Airport Connector project provides a transit link between BART and the Oakland International Airport which was constructed using a design-build delivery system. The 3.2-mile Automated Guideway Transit system operates in an exclusive right-of-way and connects the BART Coliseum Station to the Oakland International Airport. The aerial guideway structures are supported on approximately one hundred concrete piers. The alignment also includes at-grade structures, below-grade structures, and three stations. 

EMI was the geotechnical engineer of record for the design-build team. The work performed incosisted of a soil investigation program along the alignment to support geotechnical design and construction of the subsurface structures. EMI alos provided foundation design recommendations for all deep foundations. 

The below-grade structures consist of U-shape trench walls and a cut-and-cover tunnel. EMI provided earth pressure recommendations to all below-grade structures in order to achieve the most economical designs and meet constructability requirements.
