Today, with the development of technology, various buildings can be constructed in the field of architecture, and the size and complexity of construction are increasing, and the life cycle of buildings is also increasing. As a result, the importance of technology and systems that can maintain and manage not only old buildings but also newly constructed complex buildings is emphasized in modern society. Therefore, in this study, we propose a methodology to improve the efficiency of utilizing MR in the visible aspect of the maintenance of buildings and try to find a way to improve the efficiency of the actual worker by verifying the feasibility of the methodology. The information obtained from the BIM model was uploaded to the MR device, confirming its effectiveness in terms of visibility. We have developed an add-in that can complement the interoperability problems such as data exchange and uploading through the data that can be obtained through the current limited BIM model. By integrating it with other technologies such as artificial intelligence in the future, It is expected that we will be able to fill in deficiencies other than the problems of visualization presented.
