The multi-billion dollar Transbay Transit Center will replace a bus terminal near San Francisco's Embarcadero with a regional hub that links the city to eight Bay Area counties and beyond with rail and bus transit systems. The new California High Speed Rail will also travel from the Transbay Transit Center to Southern California, once that project is completed. Construction of the transit hub began in 2011 with the final completion currently scheduled for 2018.

The contractor required pipe in lengths from 40 feet to 70 feet with a unique wall thickness of 1.125 inches to 1.5 inches to support the steel wide flange beams of the shoring walls inside the 60-foot deep excavation.
