The Jakarta Metropolitan Area has long been known to be frequently hit by floods. To anticipate that flooding in Jakarta will not get worse, we need a pump system that temporarily accommodates water to a storage pond. In this project, a pump house will be designed located in the Bojong reservoir, Rawa Buaya Village, West Jakarta. The pump house design includes structural, geotechnical, and water resource management aspects. This pump house designed has an area of 8 x 16 meters with a height of 10 meters. There are two floors above ground level and one floor below ground level. the first floor above ground level is intended for the location of the flood pumps along with the availability of the remaining land intended for pump maintenance rooms. The second floor is intended for offices and operational space for equipment such as a set of hoist cranes that will be installed at an elevation of 8 meters above the ground. The hoist crane is installed with the help of 4 corbels at each end where the corbels are attached to the main structural column. The roof frame is composed of steel components where the steel profile is adjusted to the needs. All the main structural loads will be supported by the raft foundation. The floor below ground level functions as a storage pool with the perimeter of the pool being a wall plate that simultaneously holds the soil load. The load from the main structure is transferred to the raft foundation with an area of 10 x 18 meters. The modeling was carried out using the SAP2000 software with the external loads reviewed were earthquake loads, wind loads, and rainwater loads. This structure has seismic category D, but the selected structural system is the ordinary moment resisting Frame System. The consideration for choosing the ordinary moment resisting Frame System is because the structure belongs to risk category I and only has 2 floors which is not the center of the location of human activities. Detailing of structural elements in the form of beams, columns, plates, and corbels refer to SNI 2847-2013. And for steel, components refer to SNI 1729-2015. Detailing of these structural elements is done by manual calculations and with the help of software such as SAP2000 and PCA COL. As for the detailing of wall slab elements and raft foundations, it is done manually through the help of ETABS software.
