Abstract: The Industry Foundation Class (IFC) is an international standard which describes building and construction industry data. IFC has been widely developed and applied in architecture fields, but has relatively less research on alignment-based infrastructure projects such as roads, bridges and tunnels, which hinders the data sharing in these areas. In this paper, methodologies to describe the spatial location, geometry and other attributes of bridge superstructures based on IFC4x1 schema are introduced. This paper also presents an approach to map data from IFC to MIDAS Civil. Additionally, a prototype is developed based on the open-source library XbimEssentials to verify the approach presented.
