Role-based access to facilities lifecycle information on RFID tags

Radio Frequency Identification (RFID) based systems have been used in different applications in the Architecture, Engineering, Construction, Owner and Operator (AECOO) industry. Applications are mainly designed for specific lifecycle stage and serve the needs of only one of the stakeholders. This would increase the cost and the labor for adding and removing tags and eliminate the chance of using shared resources. In this paper, the usage of tags permanently attached to components is proposed where tags are attached at an early stage of the lifecycle and the memory of the tags is used during the lifecycle by different stakeholders. Using a Building Information Model (BIM) database is proposed for tackling the interoperability issues allowing different users to access and share the data. It is also proposed to securely and efficiently store data on RFID tags in ifcXML format using multi-level encryption together with role-based access control. To explore the technical feasibility of the proposed approach, a case study has been implemented and tested at Concordia University.
