Integration of building information model and RFID tag

Abstract

Building Information Modelling (BIM) creates a way for all parties to share, exchange, and manage building information throughout the lifecycle of the building. On the other hand, radio frequency identification technology (RFID) has become one of the key technologies for automatic data collection and information storage. RFID can store building lifecycle information and context-aware information in a distributed database, so it can be considered as a component of the building information model. Therefore a standardized definition of the RFID components in the BIM is required. This paper proposes a standard method for adding RFID data definitions to BIM, and maps RFID data to related items in the BIM database. This study also defines the relationship between RFID tags and building components, and proposes the use of predefined relationships. The method of associating BIM data and RFID data can automatically select data related to RFID tag data by the relationship defined in BIM. Finally, the technical feasibility of the proposed method is proved by actual case test in the existing BIM software.
