IIRC, Ponte Morandi was basically a catastrophe from conception to collapse. They wanted a concrete bridge because steel was considered too expensive, but the amount of steel required for the reinforcement likely ended up being more than a pure steel bridge would require. The concrete also made it basically impossible to perform any sort of maintenance on the covered steel members, and also trapped moisture against them. Notably, Genoa is a port town, so the bridge was also exposed to significant amounts of salt, all of which combined to accelerate corrosion and make it almost impossible to detect and repair.
It's strange because as soon as I heard "cables encased in concrete" my non educated mind thought that is a bad idea. How can you detect problems or service them?
The gentleman commenting that the Morandi bridge could have been rebuilt (even a temporary structure) in several months, does not understand engineering. Amateurs always think it is easier than reality, and professionals usually understand. Most simply do not understand the complexities. Green's theorem: "Anything is possible, when you don't know what you are talking about".
Cheap, Fast, Quality/Safe. Pick two. Fast and Safe won't be Cheap. Fast and Cheap won't be Safe. Cheap and Safe won't be Fast. This is the general rule for most things, but *especially* any infrastructure. Let alone if you live somewhere where if you dig anything you hit an archeology site.
I've watched enough disaster breakdown videos to know that if there’s ever a fire in the building I'm in, I'm evacuating. You can tell me it's fine and to stay put, but I'm only going back in once the fire is out.
That fire was insane, there's No way that should've burned that quickly, what did they use, it's almost as if they built it like a fire trap from the start. Negligence to the Nth degree.
The foam insulation in the new siding that they added to the face of the building wasn't rated for high rise structures. It's essentially accelerant once it ignites so the whole building burned from the outside in as it ignored any fire safety measures within the building. It's like being wrapped in oil rags.
Polyurethane: The same foam that killed nearly all in The Station nightclub in 3 minutes and killed several firefighters in a furniture store. Polyurethane fire spreads rapidly and the fumes are deadly. It makes the best glue, padding and insulation because of it's many air cells -hence polyurethane is everywhere. Polyethylene and polystyrene are similar, but vary by density (number of air cells).
With the bridge, collapsing, if there was one silver lining to it is that it happens on the day it did and not one day later whenever the summer holiday would’ve started and the bridge probably would’ve been completely packed with cars.
Does Europe not teach fire evacuation of stay low and crawl out, never stay in a burning building, not have fire eacapes, not have building wide fire alarms that go off when smoke is detected etc?
From the moment Insurance Companies put a value on a life. the mathamatics for saving money on these projects became easy. Grenfell Towers was a prime example of this risk and payout policy. If we use cheap dangerour products and save X amount. how much will we have to pay out when it goes wrong? X - Y. + Profits from new higher quality structures for a "better class of people".
The story of the Morandi bridge collapse sounds a lot like the collapse of the Key Bridge of Baltimore, Maryland back in March of this year. Perhaps one day that story will be told in a documentary.
They can plan and plant a rare Japanese cherry tree for each of the deceased but they couldn’t compensate the victims. Sounds like they celebrate their victims deaths more than they value their survivors
It would have been interesting to have seen a timelapse of the trees turning into bloom in the spring at Eschede. Perhaps they can edit and extend the video to include this item.
"Went back to solid wheels" after finding No Cracks on wheels that were new or re-profiled up to 5-6 times??? It's CLEAR that the railroad company didn't like spending money on NEW wheels! Use NEW wheels ONLY on high-speed trains, and after those have to be re-profiled use them on low-speed and cargo only! It AIN'T ROCKET SURGERY!
Do we really need, ma tanto di capello e arie d'importanza, to establish that putting steel that rusts inside any object of concrete will result in exactly what happened in Genova?? Italy has earthquakes regularly and other destabilizing earthmovements. This can and does create microcracks where rain seeps in and as rust expands = bye bye construction.
Rust. The bridge had steel inside concrete close to area where water over decades was seeping in. There was reports apparently about the condition- and I believe several attempts were made to "remedy" the problem- But the PROBLEM was never fixed- just coated and covered.

That's exactly what happened.
Rusty steel encased in concrete made it impossible to service.
They already knew the steel was rusting.
Like the Surfside, FL condo collapse a couple years ago.

Shouldn't compare to the Brooklyn Bridge as its engineering, workmanship, and materials are outstanding. It was built in 1869-1883. It will not fail.
As long as it is maintained properly, the Brooklyn bridge will stand forever.
They truly don't make things like they used to..

@@rdallas81Yes but usually wealthy countries like Italy have top level engineers and some of the world’s best bridges/infrastructure.

But why make it seem like they did it because poor people were going to live there?
Fitting for who lived in it. ❤

Expert claims the bridge in Italy was sound, but it shattered - is that sound!

one house near the rail had a car in their front yard
5:04 😳 that is a terrifying view
Good documentary

I particularly remember the Grenfell Tower fire. Awful tragedy. I'd never live in high rise!!
Bummer, no comments; a great video though! Thanks 🙏
Probably cuz it's only 5 hours old👍
And by the timing of your comment I'm pretty sure you must have watched it within the first half hour it was out

!00% correct on what you said the Cargo ship bump into the Key Bridge and it collapsed like a house of playing cards
@@rogerstlaurent8704it was really weird. The bridge collapsed so easily.
Wish I could share these with past people

They're not that rare and are really cheap like $100-250 per tree

Yes, it's not luck, it's not a miracle, it's ALSO NOT UNEXPLAINABLE! It's called PHYSICS! 😂

Those who knowingly put money over safety will have to explain that decision in the next life.
The veiw to like ratio scares me
covering steel with plastic polymer would prevent oxydizing

You mean the "Euro Truck Simulator" yes?
