– Oakland, California –
This excavation in downtown Oakland extended to depths of over 30 feet. Limitations and added challenges included multiple adjacent structures, in particular the 19th Street BART Station located almost directly behind the shoring wall. The shoring consisted of a cut-off wall adjacent to the 19th St BART Station with one row of internal bracing. A traditional soldier beam and wood lagging system with tiebacks was used at all other locations.
