The first theoretical part of the master's thesis deals with the railway infrastructure design basics. We are discovering the regulations and standards that guide and enable quality design. At each stage of the project documentation we define the scope and the detail of the project design. Project information is the essence of the second theoretical part. We searched for the key information that constantly complements throughout the whole life cycle of the railway infrastructure from its design to the operation and the maintenance at the end. In continuation we are introduced to the concept of BIM, its definition, standardisation and development through time. Further, we define the importance of the BIM approach in the railway infrastructure. We explore the advantages and benefits of using it and also the challenges at implementation of BIM into practice. The emphasis is placed on the development of standardisation for the railway infrastructure data exchange. The acquired theoretical knowledge is used in the information model making of the railway section Brezovica–Preserje project. We start the project by collecting the relevant data and information, continue with the horizontal and vertical alignment designing and finally arranging the cross sections. Further we create 3D model of designed railway track (super structure and substructure) and also all other models and their elements (noise barrier, drainage, railway electrification system, railway platform). Together they form the whole. We define attributes to the elements and export the individual models to IFC. Using Navisworks, we combine models into one main information model. We also add the time and costs (5D model) component. At the end we do the visualization of the designed project with Infraworks software.
