This work involves extending the approach light (10 side) bridge on the west side of the runway by 60 meters in order to secure a safe area at the end of the runway at
Precasting of pier concrete makes it possible to manufacture it during the day in a land yard, and bulk installation at the installation site reduces work at high places on the sea at night, reducing the number of skilled workers by a total of 822 people (approximately 46%) compared to the cast-in-place method. In addition to reducing the number of offshore construction days by 52 days (approximately 47%), we were also able to reduce the risk of disasters by reducing nighttime offshore work. In addition, by installing an installation mechanism that matches the dimensions of the pier precast member to the head of the steel pipe pile based on the 3D model, we can ensure the installation accuracy of the pier precast member during night work when guidance using surveying equipment is difficult. At the same time, we aimed to shorten the construction time.
Our company will continue to actively promote the use of precast concrete in order to improve productivity at construction sites.
