DEVELOPMENT AND EVALUATION OF A 3D DAMAGE FIGURE SUPPORTSYSTEM USING CIM MODELS
Kazuhiko SEKI and Satoshi KUBOTA
In order to allocate appropriate budgets and formulate plans to extend the service life of bridges, it isimportant to improve the quality of inspection data, which is the basis for understanding the condition ofbridges, and the use of CIM models is expected. Since the judgment results are based on 2D drawings thatshow 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 theseproblems. 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.
