One of the special features of this project is that, at the client's request, the entire project, from the preliminary planning to the final design, is being worked on using the openBIM® methodology. The relevant methods will be presented by our experienced engineers at the 21st Conference on Hydraulic Steel Construction in Magdeburg. They will provide an insight into their processes and report on the particular challenges involved in transferring the native CAD model to the attributed IFC model, some of which could only be overcome by developing customised software solutions.
