Crazy scene. No word yet on the cause. One confirmed dead but from the looks and sounds of it that number is going to be a lot higher. They have pulled some survivors from the rubble.
I wouldn't be surprised if it was a sinkhole given the nature of that area. It's tough to tell from the video but it almost looks like it started from the bottom up rather than a collapse from the top stories down.
These things are usually so over engineered that I would find it very unlikely that anything with the roof caused the collapse. Sinkhole makes sense but only if it was localized to the front columns. Looking at the pre-disaster pics it could have been precast rather than pour-in-place but even then it would be tough to see this happen. The sinkhole, poor footings, vibration theory makes more and more sense to me.
Ricin would work so much easier.My son has several clients in the construction industry. All of them are saying that was not a sink hole they said the way it went down it looks like a controlled demolition. Then you see this:
Relatives of Paraguay's First Family among the missing at the collapse.
Makes you go hmmmm...
I think this is it. Much like what happened with the World Trade Center buildings on 9/11. Once one floor failed, the previous floor could not handle the added stress/weight and it pancaked like dominoes. In the controlled demo you posted you can see the upper part of the building is still intact as it first starts to implode. If it were a sinkhole it would have looked like that IMO.I suppose someone could have put explosive on the top floors.
In demos, rebar is cut and explosives kill support up and down the entire structure at the same time during demo, to keep it from laying out. All floors collapse at the same time. To ME, it looks like the middle section collapses top down. Structure was lost on the top floors and that weight brought down the middle. Once that was gone, the right structure lost support and collapsed bottom (parking garage) up. The forensics on this are going to be in Engineering classes by Fall.
While it is too early to say whether climate change is to blame for the collapse of the 40-year-old Champlain Towers South,
It would be no shock to me if this was a building built in the 70s as a front to launder $ for cocaine.It COULD be a sinkhole. Has there been any evidence of this? On multi story structures you usually have pile that goes to bedrock. They said the building was 40 years old and also said roof repairs were going on? The one thing about concrete structures is if something happened they would still relatively stay together as the rebar inside is all tied together. It can crack and shift but even then it SHOULD stay intact to a large degree. The other thing about concrete is that it covers up what really matters and that is again the rebar. Inspectors have to be there to see the rebar before it is poured. At least they should. If not a natural event like a sinkhole, my guess would be improper installation of rebar.
Spot on.Good Lord people,
It's a legit hypothesis and an important one. Hell, it was the first one put forth on this thread. And it's as old as the pyramids. They would know if brackish waters are showing up in basements that it didn't used to. It is reclaimed land over limestone. These are facts. We know climate changes. We know average sea levels are changing. No one is challenging that they are rising. It's important to look and see if environment is a concern to old or new instruction. Nothing new, nothing to see here folks, move along.
Another report had a guy whose Ma and Grandma were in that first section that went, say the day before that she was woke by creaking. This thing probably hit critical point, just like most systems do. Buildings, particularly concrete are not designed with any kind of feedback correction. They hit a point. They go.
I'd like to have the ulta-sound imaging biz down there. Going to be a BIG demand.
