Abstract: The pile foundation of an office building was installed with Frankey technique (concrete filled driven pile). The project site is known as the welldeveloped Karst Terrain with quick sand stratum at the shallow depth. The vibration from the pile installation might trigger the ground subsidence. Different pile installation techniques were utilized for different cavity sizes, shapes and potential for the loss of cement slurry.
