The BIM method is perceived as a synonym for the digitalization of the construction industry. The application of this method enables most of all, the consistent and uniform information management and therefore affords a more efficient communication and collaboration environment to all participants in the life cycle of the respective property. Due to the essential role of the building data model within the BIM method, the requirements for modeling at each level must be clarified in detail before modeling. Some companies have internally developed and documented those requirements in their own modeling guidelines. However, small and medium-sized companies often cannot afford the personnel capacity to do likewise. The development and provision of a standardized guideline for the modeling of building data models by a neutral institution in cooperation with partners from science and economy intends to create a general foundation for the building industry in that manner. The aim of this guideline is to deliver a general framework for the creation of uniform and standardized building models. For this purpose, general regulations, such as the instruction for naming conventions, structure of the project models regarding different planning domains, or more specifically the description of the modeling of individual units, are documented. Within the scope of model elements, the guideline provides the identification in different classification systems as well as the description of the geometric representation along the levels of geometry and a detailed enumeration of the information requirements with the allocation of responsibilities for information delivery and integration for each element. Therefore, the application of this guideline for the modeling of a building data model supplies a clean information management as a basis for a consistent data transfer between different project participants. The application of the BIM Modeling Guideline as part of the exchange information requirements (EIR) is conceivable. Moreover, the provision of this standardized modeling guideline could also serve as a basis for further development within institutions.
