Abstract
Recently, the digital operation and maintenance of large-scale public venues have received increasing attention. The traditional building automation system (BAS), which can only provide information in a non-visualized way, is incapable of meeting the complex requirements of modern operation and maintenance. Therefore, a 3D-based building information modeling (BIM) technology is needed to improve operation and maintenance efficiency. In the paper, a BAS-to-BIM combined strategy is introduced, and the BIM-based maintenance object framework for large-scale public venues is re-built. The conversion method and lightweight method for the BIM maintenance model are introduced and a new type of public protocol, which can be used to attain a unified protocol layer that serves the BIM model, is proposed. In addition, this article presents the application of technologies, such as virtual/mixed reality, to improve the convenience of operation and maintenance. Finally, a practical project of a snow-sports stadium is given as an example to elaborate on the benefit of the proposed method. It indicates that the functions, for example, information integration, visualization, and positioning, introduced by BIM technology can effectively improve the quality and efficiency of project operation and maintenance.
Highlights
building information modeling (BIM) is still used as standalone information systems by building stakeholders, an integration technique including Internet of Things (IoT) sensors, facility management, building automation system (BAS) and BIM is needed for the end-user to monitor building performance data efficiently [23]
To apply BIM technology in the operation and maintenance system for large-scale public venues, new maintenance technology based on BIM was studied
This study included the establishment of the BIM maintenance model, the lightweight and online included the establishment of the BIM maintenance model, the lightweight and online loading of the BIM maintenance model, the design of a data/command transmission protoloading of the BIM maintenance model, the design of a data/command transmission procol [25] related to the BIM model, and the application of virtual/mixed reality technology tocol [25] related to the BIM model, and the application of virtual/mixed reality technolapplications [26], etc

Sustainability 2021, 13, 7937 and control, and it does not cover the actual needs of structural operation and maintenance This is because a BAS can only be used for manageable objects, such as wind systems, power equipment, but is incapable when it comes to objects that cannot be managed such as structural components. BIM is still used as standalone information systems by building stakeholders, an integration technique including IoT sensors, facility management, BAS and BIM is needed for the end-user to monitor building performance data efficiently [23]. The BAS should be expanded to all virtualizable 3D objects, such as walls, structural beams, and columns; on the other hand, the 2D-based monitoring and control method in the BAS needs to be transferred to dynamic monitoring information along with the operation and maintenance process. A case study based on a large snow-sports stadium is proposed to explain the critical functions and maintenance objects of the BIM-based operation and maintenance technology
