Slope Risk Management System on Toll Road: A case study Semarang-Salatiga Section

Landslide is a geohazard event which can be caused by several factor, such as high rainfall intensity, slope geological feature and the slope geometry itself. Tropical wet climate and typical geomorphology of Indonesia derives landslide event as common disaster during the wet season. Nowadays, the paradigm in road slope management has changed to put the Slope as an Asset, like other infrastructure. In this case study, a slope risk management system was created to assist road slope managers in planning periodic monitoring and maintenance. As the building have the BIM System, the slope can also be digitalized as GeoBIM. Based on case studies, this system can be used to inventory and create an electronic database of road slope assets. Furthermore, the road slope assets are assessed and prioritized based on geological hazards and economic consequences. In the end, each slope asset will have routine maintenance schedules, costs, and a historical data of repairs and damage. Therefore, the slope asset can be handled effectively and efficiently.
