BIM (building information modeling) describes a method to integrate and connect all relevant, building related data into a virtual data model over the whole lifecycle. The superior goal of all BIM-related research projects at the Chair of Construction Management and Economics is therefore to advance the efforts of data model standardization and the corresponding flow of information between all participants involved in a building project. To identify all relevant data, the focus of each project is hence directed to the question who needs which information from whom, how, when and what for. In this context the research project “Development of an ideal chain of process for using the BIM-method during the lifecycle of real estate” aims to develop and define a standardized and idealistic virtual chain of process using BIM. Therefore, the actual process structure (without BIM) will to be analyzed and defined in consideration of relevant regulations, interviews of experts etc. In this respect, the performance spectrum of each participant and the communication as well as information interface will be taken into account. Up from this point the process can be enriched with BIM-content to create an ideal BIM-process-chain. It will be important to develop a most general-purpose to include different variations of project organizations and market players. By doing so, it will be possible to transfer the BIM-method to all real estate and civil construction participants.
