A Study on Integrated Information System for BIM Application of Bridge Maintenance

The bridge of social overhead capital facilities in Korea has been in the construction saturation due to rapid economic growth since the 1970s, so the importance of maintenance has risen. Studies of applying BIM (Building Information Modeling) to bridge maintenance are increasing as a tool that not only accumulates information based on a 3D information model but also establishes a linkage system to manage bridges effectively. However, most of BIM studies for bridge maintenance just focus on accumulating the history information of safety inspection so that the information is not used efficiently for the maintenance. Therefore, in this study, the information items necessary for the safety inspection, valuation, and durability life prediction of the bridges are organized by analyzing existing research and guideline. In addition, integrated maintenance information system was constructed considering the linkage between each information in order to apply BIM to maintenance.
