According to increase of construction projects which is accomplished in the town, diaphragm wall method was proposed. This method diminished noise and vibration. And it is able to excavate deeper than other methods. But excavation work is difficult to maintain vertical and requires much time to work. Also the work result depends on know-how, experience and intuition of excavating machine operator. We interviewed technical experts related with slurry wall method and find equipment's characteristics. We used cost-concern matrix to investigate the propriety for the introduction of trench cutter automation. Through the research, it is proper to apply trench cutter automation.
