Information exchange process for AR based smart facility maintenance system using BIM model

In this study, we propose information exchange process for the effective integration of building information modeling (BIM) into an augmented reality (AR)-based smart facilities maintenance (SFM) system. The proposed SFM system refers to a system that combines technologies such as AR and IoT sensors in the field maintenance work. This requires the acquisition of data from various sources followed by transformation of these data into an appropriate format. Construction operation building information exchange (COBie) is widely used as a means to effectively integrate and utilize information for maintenance. Therefore, SFM system has a requirement attribute information system with reference to COBie. But this information should be linked to the maintenance work procedures in the actual use case scenario and it is necessary to define the information exchange process. To solve this problem, we uses the following methods to enable SFM system development with applications for BIM and AR technologies in the FM of the building sector of public facilities. First, it analyzes the previous studies on BIM-based maintenance works and AR technology. Second, it divides the SFM work process utilizing the BIM-based COBie system, and it defines the COBie data required for each work phase. Third, it develops a scenario-based business process modeling notation (BPMN) for the SFM system prototype. Finally, it proposes an implementation method of SFM system architecture.
