<p align="justify">Digital Lifestyle Center BSD City is a building for shopping center which consist of 7 main floors, 1 semibasement floor, 2 basement floors, and a rooftop, built in region of Digital Hub BSD City, South Tangerang. This final project focuses on design of pile foundation and retaining wall for basement excavation along its supporting system. <br /> <br /> The method for axial capacity of single pile calculation is static method formulated by Reese & Wright. Axial capacity of single pile calculations refer to allowable stress design (ASD). Meanwhile the lateral capacity was determined using ENSOFT LPILE program and analysis of group pile foundation were done by using ENSOFT GROUP program. The result from group pile analysis are deformation and forces for foundation system and each piles. Hereafter, the settlement analysis of group pile foundations were calculated for elastic settlement and consolidation settlement by using Vesic and raft equivalent method. <br /> <br /> The process retaining wall design requires trial and error method using PLAXIS 2D program. Based on that process, design of diaphragm wall which consist of depth penetraion, thickness, and ground anchor configuration can be obtained. This design was determined by limiting the deformation of diaphragm wall caused by lateral pressure. The next step is stability analysis for various type of failure such as basal <br /> <br /> heave, soil boiling and upheave. The last step of retaining wall design process is determining reinforcement for diaphragm wall based on diaphragm wall’s forces. <br /> <br /> The reinforcement requirements were calculated using PCACOL program and manual calculations.<p align="justify"> <br />
