Caisson Wall

Project Description

RWH designed the perched caisson over conventional shotcrete system that was utilized on this project. Perched caisson wall over conventional shotcrete is a hybrid system; caisson wall is installed in weak soil stratum and shotcrete is installed in competent soil/rock stratum. For this project, over half of the excavation support system is comprised of shotcrete. This design reduces material usage and decreases cost of construction.
