<![CDATA[Drainage channels are one of the complementary structures on road sections to meet one of the technical requirements of road infrastructure. This construction project is driven by a common issue, which is the overflow of the drainage system on M Yamin Street. This can be observed through the community's concerns about the numerous flood points occurring on that road. Infrastructure development should reach the community, especially low-income communities, while always considering spatial planning and the interconnectedness and integration with other social environments. The implementation method of the Drainage Construction Project on M Yamin Street, Samarinda City, includes the following steps: Preparatory work, Excavation Work, Piling Work, Installation of Precast U-Ditch using an excavator and a crane, U-Ditch with the dimensions of 300 x 165 x 100 cm is installed. It utilizes D16 - 200 mm and D13 - 200 mm steel reinforcement with concrete quality of Fc 30 Mpa, Reinforcement Work, formwork, Concreting Work uses concrete quality K 350 with dimensions of a width (b) of 300 cm and a thickness (t) of 30 cm. It utilizes Φ16 - 200 mm reinforcement steel and Φ13 - 200 mm support steel with a steel grade of Fy 350 MPa. Based on observations, the slump value obtained from K 350 Mpa concrete is 11.8 cm, which falls within the planned slump range for slab concrete work, ranging from 7.5 cm to 15 cm, finishing.]]>
