Benefits of Applying BIM+AR to Operation and Maintenance Management
To achieve effective operation and maintenance management through real-virtual integration, it is essential to establish a three-dimensional information system based on the Building Information Model (BIM). This involves creating a comprehensive 3D database and integrating various hidden details of real-world objects into the BIM platform. Using Augmented Reality (AR) technology, this information can be displayed directly within the physical space. By leveraging Location-Based Services (LBS), information and spatial data are seamlessly integrated, enabling localized building maintenance and operation management services.
The use of BIM facilitates 3D visualization and spatial information reflection within the model, enhancing reality assistance.
Application of BIM
With AR technology, BIM model information can be presented in real-time, allowing 3D data to be displayed within the physical environment instantly. This significantly improves the efficiency of maintenance and operation management. The goal is to realize the full potential of BIM, addressing the challenges faced in current on-site applications, and enabling a true WYSIWYG (What You See Is What You Get) spatial information experience.
BIM+AR Integration
By combining BIM with AR, the following key objectives can be achieved:
1. Collaborative Maintenance and Operation Management of Reality and Virtuality
While BIM models allow for information visualization, this data is traditionally limited to computer screens and lacks real-time interaction with physical buildings. Consequently, interpreting this information still requires professional expertise. By merging virtual data into the real world using AR, users can intuitively access the information they need, achieving a true “what you see is what you get” experience. This makes maintenance services more accessible and user-friendly, extending beyond just professionals.
2. BIM Information and Spatial Expansion
A core advantage of BIM is that the visualized model corresponds accurately to real-world spatial information. AR technology brings this virtual BIM data into the physical environment, overlaying virtual information onto real objects. This layered approach helps users discover hidden details about objects within the space, enhancing understanding and decision-making.
3. Localized Services Based on Structural Awareness
Beyond simply displaying information, BIM must be contextually linked to the physical environment and its objects. Such integration allows users to access spatially relevant, real-time information based on contextual awareness, fulfilling their specific needs effectively.
One practical application of BIM and AR in operation and maintenance involves conducting on-site measurements of existing vacant buildings. Based on these measurements and actual site conditions, a BIM model is created. This approach supports reconstructing BIM data for existing structures. Once a 3D database is established, the organized data can be exported for maintenance purposes.
However, BIM models reconstructed from surveys may contain spatial inaccuracies or lack precise information about elements like pipelines or rebar, which are challenging to detect and locate within the structure. These limitations can result in incomplete or missing data during information setup.
Therefore, to ensure accuracy in maintenance management, it is recommended to integrate BIM and AR from the initial planning and design phases of the building lifecycle.
BIM System
Planning a building with BIM is ideal because it allows for detailed information setup and facilitates more efficient maintenance and operation throughout the building’s life. Additionally, BIM and AR can serve as valuable tools during mid-construction phases, assisting in smooth project execution.
That’s all for the discussion on the benefits of applying BIM+AR to operation and maintenance management. I hope this article has been helpful!
