Why Nobody Can Fix This $21BN Floating Airport

2024-04-16に共有
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.

    Just to be clear, this airport is NOT floating. It is built on man made islands.
  • @MGower4465
    "Eventually, the airport will stop sinking"...and be converted into a submarine base.
  • The solution is rather simple: Ask the Dutch to fix it. The Dutch are specialized in solving exactly this.
  • @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.
  • Damn! I was a Marine stationed in Japan until 2022. Some of my favorite memories were road-tripping from Hiroshima/Iwakuni to KSI/Osaka to pick up other service members. I was mind-blown the first time I drove on the airport and realized it was an island of its own. Beautiful drive. Side note; It was also very creepy during COVID as most shops looked abandoned inside. One of the creepiest/most depressing things I saw quite honestly. Lol

    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.
  • 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 ?
  • @MissCheeseE
    I flew to that airport last year, I went to visit my family in Hokkaido, then flew to Osaka in order to go to Kyoto via train.
  • @dloui5214
    liquefaction and soil consolidation played major role for this kind of infrastructures
  • Thank you for this video.I never knew this even existed. Was good content, good speeds?Please keep it up with more interesting videos
  • They anticipated a sinking of 5.4 meters? That sounds extreme considering skyscrapers don't settle that much.
  • @rjones6219
    Going to make for interesting pre-take off calculations, with the runways below sea level.
  • I think it is impossible to simply lift the entire airport. You can only demolish it, heighten the island and rebuild the airport. And all has to be done in stages, because meanwhile the airport has to stay in use, I guess.
  • If they had built it on pillars set on bedrock and an I-beam substructure it would have worked. Or, if they had floated it on helium balloons from Walmart.
  • @pukavoket
    Next airport should be built on land, just level mountain tops, If they were able to fill..they can level!
  • Wow, thank you for that. I learned so much from that video and I’m not breaking your balls. I’m being sincere. I never knew they had a floating airport in Japan. I never knew it was sinking so again thank you for the video. I hit liked. I hit subscribed. I can’t wait till the next video, John from South Jersey
