Why Nobody Can Fix This $21BN Floating Airport

Published 2024-04-16
Kansai Airport in Japan is an engineering marvel but it's sinking and nobody can fix it. How can such a famous construction mega project go so badly wrong? Today we explore this floating airport and how engineers plan to rebuild this landmark to be fully operational again.

    The solution is rather simple: Ask the Dutch to fix it. The Dutch are specialized in solving exactly this.
  • @JDHitchman
    Just to be clear, this airport is NOT floating. It is built on man made islands.
  • @KentBunn
    Maybe they should just build an airport at the site of the mountains they removed to get the rock to build this sinking mess.
  • @user-hx6dv8em2m
    They already built it that means they can fix it. First, deconstruct all top buildings then strengthen the ground layers under sea. The matter is only how much it cost and how long it take. Also is it worth to fix ?
  • Thank you for this video.I never knew this even existed. Was good content, good speeds?Please keep it up with more interesting videos

    For some odd reason, I'm thinking about Dubai's Palm Island Project all the way while watching this. Talking about Kasai, the ingenuity of Japanese engineering is remarkable here. Their method is simple yet works. They basically slide a piece of metal plate into the suspension column to keep the ground levelled.

    This is no different than New Orleans, San Francisco, Manhattan, and many other coastal cities that were built and/or expanded atop organic material that decomposes naturally, leaving a void that causes the weighty material above to sink.
  • During the built the construction committee decided the less than ideal compaction is enough . When engineering studies show further compaction to reduce sinking is needed . So here we are . Soon they would need a higher sea wall and one of the largest pumping facility .
  • there's a way to minimise the sinking rate of the island airport . . . concentrated air pressure at temperatures not exceeding 74°C . . .

    Obviously pumping water deep below the airport won’t help, probably hurt. Sometimes this can help in areas where sinking is partly due to groundwater / petroleum has been pumped out over the years. Given possible liquefaction of the clay, it would have to below anyway.

    ooncrete grout injection? Drive some holes around the perimeter and make a sort of "batub by grouting with hydraulic curing grout?
  • @rjones6219
    Going to make for interesting pre-take off calculations, with the runways below sea level.
  • @noobsfansub
    At the price of refreshments for everyone I'm surprised it wasn't cheaper to build a new airport on the spot.
  • @pukavoket
    Next airport should be built on land, just level mountain tops, If they were able to fill..they can level!
  • @Jude74
    They will build a replacement in the area nearest to the mainland and use the old islands as a buffer. Thats the only possible solution. Japan routinely replaces its buildings because of substantial and frequent earthquakes. They knew they would have to do this again someday.

    I save beach land daily. I inject slow curing resin that hardens into sandstone.
