CASE STUDY ON THE KANSAI INTERNATIONAL AIRPORT Kansai International Airport: Structural Case Study The components that make up this airport include a 3,000 meter long asphalt runway that receives almost 150 planes a day. This runway is open 24/7, something that would've been a concern if located in the mainland urban fabric. interesting civil engineering topics civil engineering topics for presentation civil seminar topics ppt civil engineering seminar topics 2018 best seminar topics for civil engineering seminar topics pdf seminar topics for mechanical engineers seminar topic for civil engineering pdf

2. INTRODUCTION
 KANSAI INTERNATIONAL AIRPORT (KIX) is the first man made offshore
structure in the world
 Airport was designed by an Italian architect- RENZO PIANO
 The airport is situated in the middle of Osaka Bay as an ARTIFICAL ISLAND
 It was the first round the clock airport in Japan
 KIX became the landmark of Japan and inspired many more to construct
offshore structures

4. HISTORY
 1960 Kansai region was rapidly losing trade to Tokyo  planners proposed a new
airport near Kobe and Osaka
 1968 the Ministry of Transportation commissioned to study a new location for
constructing the airport (2 onshore & 6 offshore site)
 After the protests surrounding New Tokyo International Airport (now Narita
International Airport), which was built with expropriated land in a rural part of Chiba
Prefecture  planners decided to build the airport offshore

5. WHY OFFSHORE
AIRPORT??
REASONS ARE:
Less land area
High population density
Difficulty in spatial expansion of existing airport
Restricted hours of use of land airport due to aircraft
noise

 Sea bed investigation started in 1977
 Wire line boring developed by Port &
Harbour Research Institute of Ministry of
Transport
 Sea bed is evaluated by 65 bore holes 
100 & 400 m depth

9. CONCLUSION
 The Kansai International airport is constructed on an artificial island near
Osaka Japan
 The island is constructed to avoid the noise and land accusation problems in
Japan
 Sand drain method was used for soil consolidation of sea bed
 Sea wall was constructed using rubble, tetrapod, steel chambers and concrete
caisson to protect island from harsh sea waves
 Sky gate bridge connect airport to land side
 Protection of island was done by sea wall, drainage pump, underground wall
etc
