應用擴增實境及建築資訊模型於機電設施維護作業之空間分析

In order to keep buildings in good condition, MEP facilities must be maintained by regular and emergency failure maintenance. Failure events of facilities often lead to malfunction and even cause safety problems. When failure event occurs, it is required to be resolved by maintenance operations as soon as possible, so that the building function could be restored without too much loss or even damage. When it comes to maintenance operations, it is critical to carry out facility maintenance efficiently. To achieve this target, maintainers are required to acquire sufficient knowledge of facilities and also information about the environment of maintenance operations. So far, there have been studies improving maintenance process with BIM and COBie spreadsheet. However, researches about spatial analysis for maintenance, which is to obtain environment information, are rare and needed to be improved. This study employs AR and BIM to construct a mechanism for maintenance simulation and on-site spatial analysis. BIM is used to propose a maintenance plan via 3D simulation, and AR is applied to implement on-site spatial analysis. With the on-site analysis mechanism, the content of previous plan can be verified and more details of actual environment can be discovered. With the proposed framework, the information of maintenance can be more complete and meets the needs of actual maintenance operations.
