As the global movement toward decarbonization is gaining momentum, the importance of low-carbon construction is becoming increasingly important for port construction in Japan. In this study, as a fundamental study for low-carbon port pier construction, CO2 emissions during construction were compared between conventional in-situ casting and PCa pier construction methods. As a result, the most effective method for low-carbon pier construction was to reduce the quantity of steel materials such as steel pipe piles and rebar. It was confirmed that factory PCa is a superior construction method not only in terms of process shortening and productivity improvement, but also in terms of supply chain for port pier construction.
