Building Information Modeling (BIM) is frequently presented as a method for revolutionizing the building sector with no questions asked about the precise reasons for this claim. This seems to follow the reasoning that BIM is coming because BIM is coming. Yet there are several questions which need to be answered: What exactly is BIM? How are projects carried out using BIM? What are the benefits of BIM? What role does software play? In this context the main focus is on the discipline-specific model »building automation« and the elements of this model. This seminar offers, primarily to manufacturers, a first insight into Building Information Modeling (BIM).
