Malcolm Drilling Installed Drilled Shafts and CFA Piles at Chase Center.

For this high-profile sports stadium and event venue, Malcolm proposed a combination of drilled shafts and CFA MEGA piles to accommodate the variable soil conditions and design requirements. Drilled shafts, socketed deep into bedrock, were used wherever high axial and lateral loads needed to be transferred into the ground. CFA MEGA piles were used whenever the overburden provided sufficient load-bearing capacity for lower loaded structures. The finished foundation includes over 1,000 CFA MEGA piles and 300 drilled shafts with the deepest element reaching 170 feet. A fleet of up to 5 drilling units with multiple service cranes was used to deliver the necessary performance to install all elements in a record breaking period of less than 3 months.
