The digital transformation does not spare the construction industry. A promising future topic is Building Information Modeling (BIM), the digital representation of all relevant properties of a construction project as a valuable shared knowledge resource. Our first pilot projects have already proven successful.
The acronym BIM for Building Information Modeling is the designation of a forward-looking working method for the connected planning of construction projects, which goes far beyond the actual planning process. In addition to digital innovation, BIM holistically considers the entire lifecycle of a construction project – from the earliest conception to demolition.
BIM enables this through the digital capture, modeling, and combination of all relevant building data, thus providing a valuable shared knowledge resource as well as a reliable basis for decisions throughout the entire planning, construction, and usage phase.
Especially in the bidding phase, BIM-based, intelligent 3D models offer a clear advantage, as they significantly reduce the workload. Instead of relying on a multitude of traditional PDF plans that can vary in quality, a standardized and visually appealing BIM model provides a precise basis for cost estimates. With just one click, for example, all relevant concrete positions can be extracted from a model – a particularly crucial factor for review and validation.
We have closely examined BIM in the context of two exciting pilot projects: the two tram line projects "Wiedner Hauptstraße" and "Universitätsstraße," which were made possible through the collaboration of our subsidiary Kallinger, the BIM-Infrastructure (DCS) specialist group, and the Vienna/NÖ civil engineering department. In both projects, 3D models of the tram line were created already in the bidding phase, and the operational units have already received a positive award decision for both projects. The use of 3D models will also play an important role during execution.
