Foundation and basement excavation design are one of sub-structure worls that are carried out in the building design. The Jurangmangu Station redesign project comprise of two main building, station bulding and food court building. Station building has five typical floors while food court building has two basement floor and two typical floors. The soil condition in project site is consisted of clay soil layer and sand soil layer with hard soil layer located at 9-12 m deep. The foundation design was carried out using a drilled pile foundation with diameter of 800 mm and 1000 mm. Three types of foundation configuration are used in this design, that is B-1000, C-800 and C- 1000. Foundation analysis was carried out through manual calculations and LPILE and GROUP software in analyzing the lateral capacity of single piles and pile groups. The settlement analysis observed are elastic settlement, consolidation, and differential settlement through manual calculation. The design of the 6 m depp excavation was carried out using diaphragm wall with a single layer of ground anchorage at the elevation of -2 m. Analysis of global stability and lateral deformation was carried out using PLAXIS 2D.
