All are Seoul-based. Daewoo and Samsung opted to build scaffolding atop the third floor and erect roof trusses piece by piece. Hanjin assembled trusses atop the third floor and then jacked the entire roof section up into place. Forming an arc between current runways and the site of future runways, the terminal is roughly 1,066 m long and 149 m wide. A permanent, automatic dewatering system and sheet piles lining the building periphery minimize groundwater penetration.
Tunnels provide terminal access below the runways.
Terminal construction was substantially completed last month, and tenant fit-out and commissioning of mechanical and baggage handling systems starts this month. Kim Chan-Souk, a manager in IIAC's management and planning division, says ample time was deliberately left to test all equipment and systems. IIAC had planned to launch operations in January 2001, but airlines convinced the company to delay the opening until well after the year-end travel period. A final opening date is yet to be set. On the third floor, which is the departure level, KACI's design seeks to enforce feelings of airiness and lightness with dramatically exposed steel roofs and abundant use of glass, says KACI's Lee.
