Abstract: For realizing data exchange in the context of the planning and realization of large infrastructure projects, a comprehensive neutral data model capable of presenting both semantic as well as geometric aspects is necessary. The Industry Foundation Classes (IFC) provide a full-grown and standardized product model for the design and engineering of buildings. In the infrastructure sector, a comparably powerful data exchange solution is still missing. To fill this gap, this paper presents an alignment model which is based on the IFC data model and can be used as a data exchange standard for the design and maintenance of linear infrastructure facilities such as roads, bridges and tunnels. This paper presents a detailed account of the results of our data modeling activities. In particular, we demonstrate the use of the alignment sub-model by integrating it with a refined version of an existing shield tunnel product model. The proposed product model provides semantic entities, models the relationships between the physical objects and makes extensive use of the space aggregation concept inherited from standard IFC.
