It was concrete and the steel wasn't exposed which was the sad failure of New York? Corner cutting in the 70s for the World Trade Center.
Not a reasonable comparison. The method of construction (And what it was trying to achieve) were totally different.
WTC was a structuaral steel building aimed at providing large, essentially single room, floors. To the extent that there was a cost failing it was that the architects failed to ensure a structurally robust and fireproof wall around the building central core (Stairwells and lift shafts) IIRC the stair wells were only surrounded by dry wall, reasonably fireproof but totally inadequate in the event of any sort of explosion.
But then, nobody anticipated a fire fed by hundreds of tons of aviation fuel...
WTC would have likely survived any "Normal" fire just fine.
Grenfell Tower was intended to provide lots of small rooms on each floor. from what I have gleaned, it was constructed using "In Situ Concrete" IE the main structure is essentially a single casting of steel reinforced concrete (Like Petronas Towers).
This sort of structure is essentially fireproof and will withstand very high temperatures without structural failure (As it clearly has done!)
The issue wasn't the building, it was was clearly what it was recently wrapped in.
AFAIAC this isnt a "Blame" thing, I am a bit Japanese about this. There is a problem here that needs to be resolved. It is likely that there are many other tower blocks that have been recently refurbished using similar materials.
THESE BUILDINGS CANNOT BE CONSIDERED SAFE!
There is a potentially
massive and expensive problem to solve here and I
really do not want resources wasted on trying to find people to blame...
Just now, If I was somebody who lived in one of these recently refurbished tower blocks I would be currently feeling
very uncomfortable about going to sleep in my home.
I want every current resource put in to making very large numbers of people safe. The Lawyers can haggle over the corpses later...
