Building Information Modeling (BIM) is a working method in the construction industry for the optimized planning, execution and management of buildings and other structures. The focus is on the digital provision of project information. Various models form the basis for the central administration and dissemination of data. It is important to note that BIM is not software, but a working method designed to facilitate cooperation between all parties involved in a construction project throughout its entire lifecycle. BIM allows information and data in the project to be stored centrally in a 3D model. These can be called up throughout the entire project and are transported loss-free throughout the entire process. As a result, the respective project phases - from acquisition to warranty - can be coordinated more smoothly. The way for modern project management can thus be ensured from the first draft to the operation of the building.
