Main infrastructures in Korea are maintained according to the result from periodical in-depth inspection. The process is based on the ‘Special Act on the Safety Control of Public Structures’ and accompanied specific guide. The Act has mainly focused on the physical condition and safety of structures up to now. Recently we are faced with the threats coming from aging of structures and climate change. These interior/exterior changes are strong challenges to maintain expected performance of structures. What is more, convenience for people and functionality are came to the fore as important indices. In these circumstances, the government of the Republic of Korea is preparing for a paradigm shift to performance-based maintenance system which can evaluate integral condition of structures with regard to the various performances. In this study, performance indices, detailed inspection items and following inspection techniques are defined. The grade assigning method using the results from inspection and integral evaluation procedure are suggested. This can be used for establishing a improved and long-term maintenance strategy toward an appropriate goal considering various performance characteristics.
