Technology Introduction Period (1962~1990)
Rapid construction focusing on economic efficiency Lack of skill and often poor qualityLarge variety of bridge types and first cable-supported bridge in 1973
Large number of sea-crossing bridges for the development of islandsSecuring of self-reliant technology for FCM (Free Cantilevering Method) and steel box bridgesDesign focused essentially on functionality and economy

Design focused essentially on functionality and economy
• Sensor-DAQ System (since 1992)First generation of SHM systems installed in g yFCM, ILM and MSS bridges and in existing cable-supported bridgesConventional sensors, loggers and transmission methods used individually for each bridge
• Complete/Integrated System(since 2000)
Systems installed in recent long-span bridges since the design stage
