BIM has many aspects. For us, BIM means the consistent and holistic use of digitalization solutions in the construction industry. That is why we consider the entire process chain from the tendering through planning and execution to the use of a building. Our focus is on information management and the question of how to integrate all building-related information in a model. Our solution for this is 5D BIM. In addition to the classical information of a 3D model, 5D BIM models contain information time and cost factors.
