Flood damage is one of the disasters that occur every year from all over the world, so each country strives to minimize flood damage through a system development to manage the identification, response, recovery and mitigation of the damage at the national level, and Korea has also constructed such systems as the flood forecasting system and land and maritime disaster emergency operations management system. However, the sharing of knowledge according to the flooding situation is not made smoothly because the data management system is not identical depending on each managing authority. In order to solve such problems, the study was aimed to perform flood judgment and flood damage estimation by applying a technique considering the reusability Building Information Modeling (BIM) to the flood damage information management in the building from the stage of generating the information on the facility. BIM is the process or result model to maintain the interoperability of and manage to enable the reuse of the information created for the life cycle of the building.
The purpose of this study is to allow flood judgment and damage calculation in accordance with the flood water level by creating a building information model for the inner space of a building subject to life and economic damage in that it is the residential building space among the components that make up the city. In order to address this, an information model was configured by selecting data schema capable of the integration and reuse of the information, and deriving and defining the information items to meet the purpose of information management when flooded. Factors necessary for flood judgment were derived and judgment procedure was presented in accordance with the flood depth using the created building information model. In addition, the information items defined per the presented information items derivation procedure were added to the building information model for the flood damage estimation utilizing the information model. Finally, the feasibility would be verified of the economic and life damage of a building in accordance with the flood judgment by utilizing building information model.
It would be possible in the future to identify more accurate damage and establish restoration measures in an urban flooding situation if the coverage is expanded to the entire city by utilizing the method proposed in this study.
