This paper introduces an information modeling technique for road structures which include roads, bridges and tunnels. The Industry Foundation Classes (IFC) of BuildingSMART, which has become a de-jure standard for exchange of the Building Information Modeling (BIM) data in the AEC industry, was employed to develop a data model. Spatial and physical components of the road structures were identified and added into the IFC in order to capture the semantics of shape objects in a 3-D model. This paper also demonstrates how the structural components are hierarchically aggregated in digital modeling of road structures.

Bibliographical note

Funding Information:
The building information modeling (BIM) is an emerging technology providing a comprehensive framework for building of integrated information environment in construction project. It generally uses 3-D based and object-oriented modeling tools. The interoperability of the model data is also a major concern in the BIM technology. The Industry Foundation Classes (IFC) developed by buildingSMART (Liebich et al. 2010) is becoming a de-jure standard supported by commercial BIM tools for building structures.
