<![CDATA[Infrastructure development creates development in an area in the sector that is needed, such as the conversion of vacant land. The change of land use from forests to residential areas. commercial, industrial can significantly affect the water discharge of existing channels. The transfer of land functions requires infrastructure that can connect from one place to another, such as the construction of road network facilities. The Surabaya City Government through the Surabaya City Water Resources and Highways Office provides facilities such as Radial Road infrastructure in Lontar Village. The construction of new road infrastructure requires an adequate drainage system so that the road minimizes the emergence of various problems. Good drainage can help drain rainwater effectively, thereby reducing the risk of waterlogging and property damage. The purpose of this study is to find out the drainage channel work method carried out in this project. The researcher observed directly and took documentation to the field. Researchers also utilize literature, interviews, and data from companies to support research needs. So that the drainage channel construction work method is produced according to the project work plan. The observation results were obtained by the methods of scavenging work, earthworks, and installation work. There are Double U-Ditch Box materials type 150x150x120 cm fc'30 MPa, U-Ditch 150x150x120 cm fc'30 MPa, U-Ditch 40x60x120 cm fc'30 MPa, U-Gutter type 30x20x60 cm for water drainage, and Concrete Buis size 100x100x10 for infiltration wells needed in the construction of drainage channels in the Radial Road project.]]>
