installation, with additional space secured for potential expansion. In the civil Providing water and energy: laying piping for outside plant
engineering section, efforts were made to improve weak ground conditions. The utility pipes for Incheon Airport have 5 types including medium temperature

Careful attention was given to selecting the right engineering method and hot water, cool water, feed water, greywater, and LNG. Phase 4 built a plan for
implementing waterproofing measures, considering the specific characteristics of additional piping amounting to about 7.4 km considering future water demand. To
