    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.

      That's exactly what happened.
      Rusty steel encased in concrete made it impossible to service.
      They already knew the steel was rusting.

    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.

      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.

    How the hell such flammable materials were approved to clad the Grenfell tower? I'm not in the building business but as soon as you mentioned all the materials, I knew those were highly flammable. Whoever suggested and whoever approved this needed to go to jail or be charged lots of money for rebuilding.

When is the last time any project came in under budget? Iiterally cant think of anything else they could have added, to kill these people further. It's insane. Like, were they trying to free the property because its such a desirable area and they wanted to use it for other things? Watching these people cry and burn alive, will haunt me forever.
