A Study on the Integration of Bim and Mixed Reality in Steel-Structure Maintenance

In recent years, there have been numerous successful cases of three-dimensional (3D) multimedia, augmented reality (AR)/virtual reality (VR), and mixed reality (MR) applications in information communication. Additionally, building information modeling (BIM) has become the primary tool for integrating and disseminating project information within the construction industry. However, there are still many challenges related to information access and accuracy at construction sites. This study combines BIM and MR technologies to address these limitations and focuses on complex steel-structure maintenance engineering. The project information compiled in the BIM model is transformed through information conversion and made accessible to head-mounted displays using the MR application developed in this study. Case validation has demonstrated that the combination of BIM and MR technologies can reduce the time required to create MR content in construction projects and solve the problem of difficult information access at construction sites. Furthermore, the simulation analysis of steel-structure deterioration and environmental factors presented through MR can serve as decision support for steel-structure maintenance management.
