NEW AS-BUILD INSPECTION SYSTEM USING BLOCKCHAIN THAT GUARANTEES IMMUTABILITY OF CONSTRUCTION MANAGEMENT INFORMATION

Abstract

 In recent years, under the policy of i-Construction, the adaptation of information technology to construction sites has been progressing, and improvement in productivity is expected. Information obtained from construction sites is being utilized not only for construction management but also for as-build inspection. However, the process of on-site inspection conducted by a inspector to ensure immutability has not been streamlined yet. In this research, a new as-build inspection system using blockchain is proposed through the design of a system that guarantees the immutability of construction management information, the development of a prototype, and the proof of concept test.
