DEVELOPMENT AND EVALUATION OF A 3D DAMAGE FIGURE SUPPORT SYSTEM USING CIM MODELS

Abstract

In order to allocate appropriate budgets and formulate plans to extend the service life of bridges, it is important to improve the quality of inspection data, which is the basis for understanding the condition of bridges, and the use of CIM models is expected. Since the judgment results are based on 2D drawings that show the locations of damage, the drawings do not show the complicated parts of the building. In addition, some of these drawings do not have dimensions, which causes a problem that the checking process takes more time than usual. In this study, a 3D damage drawing support system was developed to solve these problems. The issues and problems in introducing the system to the practice of periodic bridge inspections are summarized through demonstration experiments, and the issues of periodic bridge inspections using CIM models are discussed.
