Each towers have 34 levels + Lift Motor Room (LMR). The height of this building is 152.9 meters. Basement has 4 levels with 14 meters of total depth. In order to maintain the stability and collapse preventing of soil beside basement, it considers geotechnical aspects about retaining wall construction. Retaining wall in Verde II Condominiums has been displaced so that retaining wall has been redisigned.The retaining wall that is used in this research is modified diaphragm wall by plugging pile to transfer entire axial loads on solid soil layer. In other words, modified diaphragm wall panels will be shorter than conventional diaphragm wall. The redesign of this building uses panel sized 0.8 x 1 x 16 m3 and square PC pile sized 50 x 50 mm2 that piled for 20 meters depth. Basement construction is conducted gradually: single pile installation, diaphragm wall installation, and slab installation by semi top down method. Staged construction analysis in diaphragm wall and soil excavation is design on PLAXIS 2D software. Modified diaphragm wall is installed on the north and south side with the each maximum deflection is 23.61 mm and 25.12 mm so have been minimum require of deflection with 140 mm. Safety factor of modified diaphragm wall bearing capacity is 3.431 > 3 (minimum require of safety factor) designed on SAP 2000 software. The reinforcement modified diaphragm wall design needs eight D29-120 for positive moment, three D29-450 for negative moment, and D13-150 for transversal reinforcement.} }
