Abstract
The exchange and provision of interdisciplinary information is a key to leverage of sophisticated crossdomain BIM applications like project controlling, simulations, energy efficiency or building automation. Thereby existing data formats, domain applications and information processes must be retained as far as possible. As current interoperability methods cannot cope with this challenge satisfactorily, the multimodel method is presented here, which enables interdisciplinary construction information processes on the base of original data. A multimodel therefore combines heterogeneous models of different domains. The loose cross-model coupling of data elements is neutrally stored in external ID-based link models. As the single domain models remain unaffected, they can still be used by traditional applications. Because of the absence of a leading or integrating data scheme, no transformation processes are required, common established data formats can be reused and the linked domain models can be exchanged neutrally. The linked data in multimodels offers an additional value of information in contrast to the single domain models. Information belonging together can be automatically evaluated by the persistent links. Thus, a multimodel appears to a user as a single self-contained information space. While the method focuses on closed world data exchange scenarios, it is not intended to form a singular project information space.
