Osaka International Airport, located in the densely populated suburbs of Itami and Toyonaka, was surrounded by buildings; it could not be expanded, and many of its neighbors had filed complaints because of noise pollution problems. In the late 1960s, the Kansai Region in Japan realized an economic need for a new airport near the Bay of Osaka. This project was being undertaken to establish a new airport. The construction began two decades after this. The airport was built on a 1.25 km u 4 km man-made island 5 km offshore at an average water depth of 18 m. The project commenced in 1986 and the airport was opened for flights in 1996. The construction cost over $14 billion.PROJECT MILESTONES Subsurface Investigation Sea Wall Construction Landfilling Terminal Construction CONSTRUCTION TIMELINE 1986- Start of the airport island seawall construction 1987-Airport island seawall construction (January) 1991- Completion of reclamation work on the airport island (December) 1996- Completion of Passenger Terminal Building (June) Architect: Renzo Piano Later on 1996- Opening of the Airport TECHNICAL REQUIREMENTS Workers, engineers, electricians, designers, scientists, geologists, environmentalists etc Construction Materials Following all regulations and bylaws (height, width, and zoning requirements etc Protection from natural phenomena like earthquakes, typhoons etc. CHALLENGES FACED Kansai sunk 27 ft by 1990 and continues to sink today. Un-conservative estimation of consolidation settlement Wrong estimate of the time required for completion of consolidation settlement Ineffectiveness of the sand drains in achieving the required success 100% Japan is an extremely high risk hazard area prone to strong earthquakes, tsunamis, and typhoons. Since the island is very close to sea level, large waves are its biggest threat.
