INTUIT DOME

The project is comprised of the new Clippers stadium and associated facilities. Malcolm Drilling and Cefali & Associates teamed up to design the temporary and permanent shoring aspects for the project. The court is sunk over 30 feet below the existing grade. While the project site is large, the below grade levels take up much of the area. Temporary earth shoring was required because cuts required excessive laybacks and due to construction access. Support of the massive cranes used for the erection of the roof trusses, in addition to ordinary concrete pumps and smaller cranes, was accommodated in the design. Earth shoring was also used for internal pools, a parking structure, storm water tanks, and a bottom-up earthen construction ramp. Most of the shoring uses cantilever and tieback-braced soldier piles. Where tieback agreements could not be secured at the site’s entrance tunnel, a cross-lot braced system was employed. The braces were placed above truck traffic. Permanent shoring is used to allow for sequenced excavation and construction of blast and MSE walls for the project’s sunken garden. Overall, the project used the most amount of steel soldier piles on a single project in the company’s history.
