This master's thesis deals with the topic “Interface integration of BIM in the digital twin of an industrial building”. The aim is to develop a generic process model for data exchange in the planning phase for the creation of a BIM factory model and its integration into the digital twin of an industrial building to conclude the research work. This study is done using the methodology of design science research. The thesis begins with an explanation of the fundamentals of factory design and operation and the current Fourth Industrial Revolution, as well as an overview of the fundamentals of BIM. The thesis aims to define a clear distinction between the terms “digital model”, “digital shadow” and “digital twin”, as there is currently no standard definition of these terms, which often leads to misunderstandings and misinterpretations. In addition, the current status of BIM in factory design and operation is considered and compared with the definition of the digital twin of a factory to provide an overview of the current possibilities of BIM along the lifecycle. Then, the interfaces that allow data exchange between BIM and DM, DS and DZ are analysed and explained using a fictitious scenario. To conclude, a generic process model is developed to illustrate how BIM can be integrated into the digital twin of an industrial building.
