<p align="justify"> Kantor Sewa Serpong is a building thatt consist of 17 floors with an office function, and 4 basements floors as a parking area in Gading, Serpong. The foundation design used is the raft foundation which met the design criteria. The design criteria include the foundation bearing capacity and settlement of the foundation. The axial bearing capacity is determined using manual calculations according to Meyerhof. The raft foundation is designed as thick as 2 m and the width of the building. The analysis of settlement was calculated and iterated by using SETTLE 3D and SAFE software. The design of excavation retaining wall used the diaphragm wall with groung anchor reinforcement that qualified the design criteria include wall deflection, excavation retaining wall safety factor, and ground anchor safety factor. The analysis of excavation retaining wall used PLAXIS 2D software with stages construction consists of diaphragm wall installation, 5 excavation stages, and 3 ground anchors installation. The excavation retaining wall has 100 cm thickness, 25 m depth of penetration, and 3 ground anchors installed at -5 m, -8 m, and -11 m elevation. The reinforcement design of foundation and diaphragm wall accordanced with the regulation of SNI 03-2847- 2013 about The Planning and Designing of Concrete Structures for Bulding Construction. The design results are in the form of detailed drawing and technical specifications. <p align="justify">
