Malcolm Drilling was contracted to install the retention system for the new Miami-Dade Courthouse.
The historic landmark known as Miami-Dade County Courthouse is a 28-floor structure that stands 361 feet tall in Miami Florida. On July 9, 2021, the Miami-Dade Courthouse was abruptly shut down for safety concerns with various floors.
Malcolm Drilling was contracted to install the shoring system for the basement construction and the deep foundations of the new Courthouse. Malcolm used Deep Soil Mixing (DSM) to construct a temporary, cantilevered gravity block wall with embedded steel beams and a bottom seal plug for a 15-foot deep excavation. The project also included the installation of 24 and 36-inch diameter CFA piles to depths of up to 110 feet. Malcolm self-excavated the pit after the DSM and CFA piles were installed.
