Horizontal Building Information Modeling: the Croatian railway Gradec-Sveti Ivan Žabno case study

According to UNI 11337, Building Information Modeling (BIM) is the process of creating and managing information about a building throughout its life cycle. One of the fundamental results of this process is a multidi-mensional model, i.e. one that goes beyond the three-dimen-sional description and offers a complete perspective of the built work. This model is developed based on information that is collaboratively entered and updated during the main phases of the project. In this paper, we present the BIM model of the Gradec-Sveti Ivan Žabno railway line developed within the international cooperation activities between the Universities of Naples Federico II and Zagreb to highlight the advantages and limitations of the methodology applied to a real railway project.
