Bandung is one of many cities in Indonesia that has high tourism as well as a business center. Space that becomes more limited and increasing demand have resulted a need for more effective and efficient solutions. One of those solutions is a mixed-use building concept. To fulfil the requirement, a commercial and hotel building named Fluid Architecture was design on strategic and culinary tourism area Cibadak, Bandung. The design of the geotechnical field for the Fluid Architecture building includes the design of the retaining wall and foundation. The Fluid Architecture building has 2 basement floors, with a floor depth of -4 meters and -3 meters. The total planned excavation is 9 meters, including pile cap excavation and additional excavation. The retaining wall for the Fluid Architecture building uses secant pile with diameter of 0.8 meters and depth of 22 meters, and is supported by strut reinforcement at the depth of 3 meters. Retaining wall analysis used Mohr-Coulomb soil modeling in the "PLAXIS 2D" application. The design of the foundation for the Fluid Architecture building starts by calculating the axial and lateral bearing capacity of a single pile. The axial capacity of the bore pile uses the ASD (Allowable Stress Design) loading method and the lateral capacity of the single pile is calculated using the "Ensoft LPILE" application. Furthermore, pile group analysis was carried out with the help of "Ensoft GROUP8" application to obtain the load that is received by each pile in the pile group. Next, an analysis of the decline was done, including the elastic decline using the Vesic method and consolidation. Reinforcement of the pile head and bored pile use LRFD (Load and Resistance Factor Design) loading method, which is obtained from the comparison between the LRFD and ASD loading. Number of pile head reinforcement is determined by the "SAFE" application, while for bored piles use the application "PcaCol". All designs refer to SNI 1726: 2019 and SNI 2847: 2019.
