Currently, the construction industry is facing a change. The new working method Building Information Modeling (BIM) comes with the challenge to adjust design ap-proaches and to overthink and redesign using proven structures and working tools. This need is immediately apparent for the realization of scales in digital building models. Where in conventional working methods scales manage the depth of infor-mation of the design, planning details of three-dimensional building models can be represented true-to-life on the screen. Furthermore, the use of predefined detailed library components implies incorrectly a much too advanced planning status. To evaluate the reliability of the content of digital building models, the concept of the LOD-specification is going to be investigated. It is therefore the objective of the pre-sent thesis to make these level of developments verifiable. This allows to receive a general grasp of the representation content of various planning stages again and helps to increase the quality of building models. For this purpose, different existent standards and their developments were investi-gated. Due to the fact, that there are no binding specifications regarding the LODs in Germany, the thesis at hand examines commonly known standards in terms of their practicability in Germany. The next step shows how a non-proprietary model check-ing can be deployed on the basis of IFC-files. To this, the IFC data model is ana-lyzed and its structure is mapped on different building elements. Even if the checking concept based on the BIMForum LOD Specification only refers to some specific building elements, it was able to prove, that these basic principles can be extent on further components of the building sector. The practical part of the thesis demonstrates the applicability of the concept of scales to the working method BIM with the help of the level of developments. The following implementation of a checking tool and the subsequent visualization of the results makes this tool even more tangible.     «
