The construction of the apartment is planned to take place in the Alam Sutera area, Tangerang city. The planning for apartment construction is based on technical drawing by architects with a little revision with regard to several issues. As for this final project, the apartment design will be planned with the emphasis in safety and comfortability. In geotechnical aspect, there will be two main topics. They are embedded wall structure design and the design of pile group foundation. Before focus on the two main discussions, the soil investigation is carried out first in order to obtain the required soil parameters. The process of analizing soil data will include several things such as boring log point mapping, determination of soil data correlations which will be determined through the results of obtained laboratory data analysis associate with boring log data for the purpose of obtaining characteristics of the existing soil. Furthermore, in designing the embedded wall, the Diaphragm Wall (D-Wall) will be use. It has dualfunction. The first one is as retaining wall it self and the second one will be as the basement wall of the structure. In the planning process, Plaxis 8.6 software will be used in analyzing the stability of the D-wall itself and the excavation of 3 basement floors which have a height around 10 - 13 metres. Mean while, D -wall’s detailed reinforcement will use CSI Col 8.0 software. The next one will be deep foundation design. In group pile foundation planning, it is planned to use bored pile with raft pile foundation as the pile group configuration which is designed to minimize the differential settlement between the bored pile which could affect the structure. As for the planning process, it is necessary to use Lpile v 2018, Group v 8.0 as basic software in determining the configuration, number, and length of the group pile, while for reinforcement detailing, SP Col 2018 software will be used. The general standard used for the above planning are SNI 8460 2017, SNI 2847 2013 and SNI 1726 2012.
