The well-documented construction inspection record is important to the success of the construction project. Along with the development of information technology, mobile devices have been widely employed to record construction inspection. In addition, building information modeling (BIM) is also used to provide information for construction inspection. However, even with the help of mobile devices and BIM, the quality of inspection heavily depends on the information retrieved to examine the on-site condition. Therefore, there is a need to develop a system that can retrieve necessary information and compare it with the on-site condition in real time to improve the process of construction inspection. This research combines BIM and mixed reality (MR) technologies to develop a construction inspection system. Within this proposed system, the construction engineer can employ the head-mounted MR device, HoloLens, showing the BIM model on the construction job site with the exact scale to retrieve the required information for inspecting the jobs in progress. In addition, by employing the function of spatial mapping of the MR device, the construction engineer can also measure and record the on-site jobs to identify the differences between the planned and the actual works in real time. Furthermore, the inspection record can be uploaded to the database on the cloud for better management. The process and quality of the on-site inspection can be effectively improved by employed the proposed BIM-MR integrated system.
