| Summary: | Mixed Income Housing in East Jakarta is a high-rise apartment project that aims to disrupt the forms of interaction or segregation present in the surrounding community. The building consists of 11 floors with 2 basement levels that serve as parking spaces. The geotechnical design includes the foundation system and retaining walls to support the basement structure.
The retaining walls are designed to support excavation work up to a depth of 7.5 meters. The chosen type of retaining wall is a diaphragm wall supported by soil anchors. The diaphragm wall is designed with a thickness of 800 mm, and the soil anchors will be installed at a depth of 4 meters. Additionally, dewatering modeling will be carried out during the excavation work to lower the groundwater level from 3 meters to 9 meters. The analysis will be conducted using PLAXIS 2D.
The foundation system utilizes bored piles with a diameter of 1000 mm, which will be connected to pile caps. The configurations of the pile caps include arrangements for 4, 12, 16, and 36 piles. Tie beams will also be designed to connect adjacent pile caps, with dimensions of 250 mm x 500 mm. The analysis will be performed using the software tools LPILE and GROUP.
