Abstract
With the wave of the Fourth Industrial Revolution, the construction industry is also witnessing the application of numerous state-of-the-art technologies. Among these, augmented reality (AR) technology has the advantage of utilizing existing 3D models and BIM data and is thus an area of active research. However, the main area of research to date has either been in visualizing information during the design phase, where architects and project stakeholders can share viewings, or in confirming the required information for construction management through visualization during the construction phase. As such, more research is required in the application of AR during the facility management (FM) phase. Research utilizing BIM in the FM phase, which constitutes the longest period during the lifecycle of a building, has been continuously carried out but has faced challenges with regard to on-site application. The reason for this is that information required for BIM during the design, construction and FM phases is different, and the reproduced information is vast, so identifying the required BIM data for FM and interfacing with other systems is difficult. As a measure to overcome this limitation, advanced countries such as the US and UK have developed and are using Construction Operations Building information exchange (COBie), which is an open-source BIM-based information exchange system. In order to effectively convert open-source BIM data to AR data, this research defined COBie data for windows and doors, converted them to a system and validated that it could actually be applied for on-site FM. The results of this system’s creation and validation showed that the proposed AR-based smart FMS demonstrated faster and easier access to information compared with existing 2D blueprint-based FM work, while information obtained through AR allowed for immediate, more visual and easier means to express the information when integrated with actual objects.
Highlights
In order for the facility management (FM) crew on site to immediately obtain the necessary information through augmented reality (AR), this study demonstrated the use of the AR data conversion approach, which converts building information modeling (BIM) data through a Construction Operations Building information exchange (COBie)-based information exchange system
This study presents the system design and development of the BIM-based smart facility management system (FMS)
Technology to on-site maintenance work. To this end, existing studies on BIM-based maintenance as well as AR applications in construction were analyzed, and on-site FM tasks that can benefit from applying AR technology were identified
Summary
For effective and systematic operations and maintenance of the facility, the information on the facility generated during the design and construction phases forms and is used as the basic data for the facility management system (FMS). Defining and verifying the required information for the operations and maintenance of the facility, thereby using them in building baseline data for the FMS, requires much time and associated cost. To alleviate these difficulties in the current FMS set-up process, building information modeling (BIM) technology is being adopted and is seen as an alternative for effective and systematic facility operations and maintenance. The BIM model is made up of objects, properties and relationships, and as the object defines all properties and relationships, it can be used to manage the required information for FM based on function, space and purpose
