The impermeability layer has decreased the surface storage ability, groundwater level and the time of concentration, and increased the peak flow of storm water runoff and urban floods. Due to the fact that developing the drainage functions in urbanized areas requires a considerable amount of burden in public expenses, which in reality makes it difficult to proceed with, it is necessary to apply the Low Impact Development (LID) concept and transform the drainage-oriented water management to water use and environment- friendly management. As the direction of recent design methods has been shifted to BIM (Building Information Modeling) and GIS (Geographic Information System), it is expected that the LID design will also be shifted to the same direction. Therefore, the related analytical solution is needed, and by using Autodesk® Storm and Sanitary Analysis (SSA) it will enable an interpretation of the city outflow and analysis by making connections with BIM and GIS, and this study’s analysis included making a connection with the runoff model of another city SWMM. This study helped to minimize data loss and rework the process of constructing the network data using the BIM design method and the public GIS followed by the analytical work, and to quickly construct the current network writing by utilizing the public GIS.
