Einblick in das Forschungsprojekt Metadaten und Prozessmodelle für Open BIM in der TGA (metaTGA)

Building Information Modeling (BIM) is one of the key technologies in the building and real estate industry and will have a great impact on the value chain of all stakeholders along the building sector. BIM methodology supports the overall building life cycle in which mechanical, electrical and plumbing (MEP) plays a central role. Properties such as the energy consumption and operating costs of a building are fundamentally determined by the quality of MEP planning and implementation. Studies have shown that open data interfaces such as Industry Foundation Classes (IFC) and the interoperability between different software environments are especially important for MEP planning. Open data exchange with Open BIM requires standardized data models and its modeling processes. Several research studies show that Open BIM data models for MEP are not yet fully applicable in real world projects. This applies to the MEP data models themselves, as well as to process models that describe the level of development and responsibilities throughout all phases of a BIM project. The aim of the research project "metaTGA" presented in this paper, are the design of a methodology for developing data- and process-models and to apply and validate them by modeling selected MEP systems. This paper presents the first results of the project and it provides an overview of the methodology of metadata harvesting shown for a silencer component as example.
