Intuit Dome includes the Clippers arena and associated facilities. Malcolm Drilling and Cefali & Associates worked together on temporary and permanent shoring for the project.
The court sits more than 30 feet below existing grade. Because below-grade construction occupied much of the site, temporary shoring was needed to limit excavation layback and preserve construction access.
The shoring design accounted for cranes used to erect roof trusses, along with concrete pumps and smaller lifting equipment. Temporary earth support was also used around internal pools, a parking structure, stormwater tanks, and a bottom-up earthen construction ramp.
Most shoring used cantilever and tieback-braced soldier piles. Where tieback agreements could not be secured at the site entrance tunnel, a cross-lot braced system was used with braces placed above truck traffic.
Permanent shoring supported sequenced excavation and construction of blast and MSE walls for the sunken garden. The current site notes this project used the most steel soldier piles on a single project in the company history at the time described.
