Securing Miami-Dade Courthouse by Installing a Retention System
Malcolm Drilling was contracted to implement the retention system for the Miami-Dade Courthouse, a historic 28-floor landmark in Miami, Florida. Following safety concerns leading to the abrupt closure of the courthouse, Malcolm Drilling took charge of installing the shoring system for basement construction and deep foundations. Employing Deep Soil Mixing (DSM), Malcolm constructed a temporary cantilevered gravity block wall with embedded steel beams and a bottom seal plug for a 15-foot deep excavation. The project involved installing 24 and 36-inch diameter CFA piles to depths of up to 110 feet, with Malcolm also handling the self-excavation of the pit post DSM and CFA pile installation.
