Having successfully completed the Gumi High-Tech Valley project, the final stage of National Industrial Complex 4 development, POSCO E&C also built a large-scale site spanning 3,768,595 m2. For the East Breakwater Construction Works for the Second Stage in Ulleung (Sadong) Port, we manufactured a 14,000-ton caisson, which is the largest-capacity in Korea, and transported it for 210 km on the sea.

We successfully completed this project through the long-distance marine transportation, which had never been attempted in the construction industry.
