Construction industry becomes large and complicated as that occurred in the construction processes and operations, and the growing social demand for more systematic and efficient methods of integrated management increases. Current facility maintenance system has been regarded as large labor-intensive and fairly stagnant, and faced on several issues including inefficiency in cost and time to collect and utilize various field information. Thus, this paper presents a maintenance prototype utilizing NFC technology and smart devices to efficiently collect and manage the field information in the course of the construction processes. By choosing dam facilities as a case study, construction data for dam inspection and maintenance were classified according to dam maintenance guideline, and database structure was constructed to incorporate with the NFC tags and smart device interface. The system prototype presented in this paper would improve the quality of the dam facilities maintenance system and provide business convenience and usability by contributing increased efficiency of field information management and sharing.
