project snapshot:

Nicholson was awarded the contract to build the basement and foundation structure for a new facility in Miami, Florida designed to treat cancer patients with proton beam technology. Nicholson's foundation solution included the use of Deep Soil Mixing (DSM) and Augercast Piles (ACP). The DSM was used to construct a temporary, cantilevered gravity block wall and bottom plug system to allow for up to 25 feet deep excavation depth. In addition 234, 18 inch  ACPs were installed at depths of up to six feet. Once the DSM and ACP work was completed, Nicholson self-performed the excavation of the pit.
