In order to maintain and manage buildings, it is necessary to understand information on the facilities and equipment provided in the building, for which design drawings are required. However, there are many buildings for which design drawings are not kept, and there is a possibility that design drawings will be destroyed after the statutory 15-year period. In this study, a 3D model was constructed based on point cloud data created using a terrestrial laser scanner and camera, and attribute information was added to it to construct BIM data, with the aim of maintaining and managing existing buildings that do not have design drawings. The method of utilizing IFC data was proposed to enable data linkage between inspectors and managers involved in the maintenance and management work.
