Regarding social infrastructuresin Japan, the ratio of facilities constructed 50 years ago or more is on the rise. Inaddition, since it is estimated that the number of employed persons in the construction industry will decrease in the future, it will be difficult to properly maintain the social infrastructure. For this subject, methods for improving maintenance and efficiency by utilizing BIM / CIM and point cloud data are becoming common. In addition, a method for product model using point cloud data, in which point cloud data is divided for all of the features and parts, has also been proposed. Therefore, in this research, the method of product model using point cloud data is compared withother data management methods from the viewpoint of the accuracyand freshnessof the data to be maintained. We verified the effectiveness of the point cloud data as a product model method.
