Surabaya is one of the largest cities in Indonesia. Activities and movements that occur in the city of Surabaya also continue to increase. For this reason, facilities and infrastructure needed to support the movement are needed, such as the Joyoboyo Intermodal Station. In the planning of the Joyoboyo Intermodal Station there is an underpass. So that the design of foundation systems and retaining wall systems for underpasses needs to be well planned. In this structure the foundation system used is the bored pile foundation by determining the axial carrying capacity of a single pile based on the Reese & Wright approach. Determination of the lateral bearing capacity of a single pole is calculated using the LPILE software and checking using the Broms method. Pile group analysis and settlement analysis are performed using manual calculations. The retaining wall used for the underpass structure is diaphragm wall with a ground anchor support system. Analytical calculations are done manually while the stability analysis model, displacement, and internal forces are performed in the PLAXIS software. The design of reinforcement of diaphragm foundations and walls follows the SNI 2847-2013 regulations on Procedures for Planning Concrete Structures for Buildings.
