Project Type: Site Work
Designed excavation shoring for one level below grade basement for UCSF’s New Student Housing project. The plan dimensions for the site measured approximately 200 feet by 200 feet. The shoring design involved cantilevering steel soldier beams and wood lagging. The soldier beams were spaced at 6 feet on center to minimize the lateral tip deflection so that tieback anchors would not be necessary. A factor in the shoring design was the evaluation of the adjacent Caltrans 18th Street Overpass to determine the footing locations and depths and whether there would be any impact/surcharge on the bulkhead.
