The Grid Apartment in Gedebage, Bandung City, is a building consisting of 3 towers connected by a 1-floor basement. This final project aims to design a foundation that can support the load of the superstructure of the building and wall to retain the soil to be stable around the construction area. The foundation and retaining wall design is based on SNI 8460:2017 and SNI 1726:2019 about Geotechnical Design Requirements for Earthquake Resistance. The designed retaining wall is of type a secant pile. The staged-construction model and analysis of the secant-pile have been conducted with the case of the PLAXIS2D computer program to determine the deflection and safety factors in undrained and drained conditions. Dewatering is designed for the excavation to lower the groundwater level to the designed depth through seepage analysis and rainwater. The pilegroup foundation is designed as a driven pile foundation with a pile cap connected by tie beams. The foundation is designed to satisfy axial capacity, lateral capacity, and pile deformation limits for service load conditions, nominal earthquakes load conditions, and strong earthquakes load conditions. The foundation model uses LPILE and GROUP applications to determine the lateral capacity of the pile. The foundation settlement is modeled with the SETTLE3D software application and checked against applicable requirements.
