The total tunnel shell including the track system is modelled and the options and advantages of BIM are presented on the basis of this pilot project.
Inter alia construction cycles can be simulated and thus better visualized. Apart from a multitude of information like cubature, material and costs the individual modelled objects also contain information when and where to be installed.
It is also possible to use the 3D models for virtual runs independent of operation and train traffic enabling better preparation for surveys and maintenance.
Furthermore digital design does not have to be merely inspected on the screen. By means of augmented reality digital models can be projected onto the environment by means of special glasses.
Therefore, required instructions or a maintenance plan can be shown well visibly directly next to the device for example during maintenance works in the tunnel.
