BIM Bestand - BIM based inventory management of buildings

Building Information Modeling (BIM) play an important role in the architecture, engineering and construction (AEC) industry. The success of BIM in facility management (FM) depends on the development and integration of open collaboration platforms and data exchange formats. The maintenance of mechanical, electrical and plumbing (MEP) systems is one of the fundamental activities in facilities management. Comprehensive semantic and geometric data transformation from the BIM‐Model to the FM information systems, such as electronic document management systems, computerized maintenance is crucial for the BIM integration in facility management, to avoid labour‐intensive and inefficient processes. A comprehensive literature review pointed out, that FM organizations pushing the use of BIM, but it is still not clear, how an effective data transformation from an “As‐Built Model” into the operation and maintenance can be realised and what the requirements are for those processes. Moreover, the FM software applications in the common data environment are fragmented. As a consequence, an interoperability among different proprietary software tools is an ongoing challenge. Furthermore, existing open‐BIM standards such as the industry foundation classes (IFC) are hardly used for BIM, because there is a lack of comprehensive data models for MEP components considering to requirements of FM. The aim of this research project is, to create semantic and geometric BIM data models for MEP systems, considering to the needs and requirements from FM with use cases and their demonstration in the field as a best practice in two open BIM case studies. For this purpose, employer’s information requirements (EIR) for FM are described. In a next step, quality parameters for BIM models can be defined and implemented in the use case management. The developed BIM MEP‐models are used and tested in four use cases. As an example, they are implemented in typical scenarios from FM as a best practice model in the “Büro‐Plusenergiehochhaus der TU Wien” and a building object of the Vienna city airport. For the implementation of the use cases in a digital open BIM workflow, the connection of improved IFC‐data models for MEP‐systems to existing software tools for FM (SAP, ERP etc.) will be developed and demonstrated. Finally, the BIM‐FM data and process model are validated and optimised, by reproducing the use cases in the training control centre in the Vienna city airport (“digital twin”). The findings of these use cases will be documented in deliverables as “lessons learned”. Various stakeholders are involved in the research activities to achieve a broad level of acceptance of the results. Letters of interest (LoIs) from trade associations and industrial enterprises underpin the interest in the project. Thus high priority will be given to an open knowledge exchange and transfer. The developed data and process models, the approaches taken during the use case management in combination with the two case studies will be disseminated openly.
