Building collapse on east coast of florida

Chemical engineer, yo...
Shit like this only happens in third world banana republics...........never mind.
I wonder what the guy living in 3B had on Hillary........
Not to stoke the fire, but I read it was across the street from one of prez trump's kids
Sinkhole? Florida has a lot of them........
I'm not a structural engineer (mechanical HVAC) but being 45 years in the commercial construction business
I've learned a thing or two. That looks to me from the pics to be a mild steel (re-bar) concrete slab building and not PT (post tensioned slab). I f they were working on the roof as the one article stated, I'm guessing there may have been a lot of rain infiltration from the bad roof and over time the re-bar rusted out and the concrete may have even degraded a bit and the roof slab pancaked.

Normally a sinkhole that swallows a building is fairly obvious. I'm guessing someone on the construction crew said something like, "Hey, what does this screw hold," just before removing it.
Very interesting the lights stay on in the part of the building that collapsed for at least the distance it took to fall downwards 1-2 floors. SCARY stuff!!!!
I'm waiting for the tinfoil hat crowd, to start calling this "Building 11" or some-such.

This was going to be my assumption. But, reports were that a hotel was having some construction being done to it close by, might have contributed (??). Mac
The building just got the COVID jab that morning. 
Being Miami, with lots of local sand, the contractor could have save a lot by using beach sand for the concrete rather than paying for washed sand. Caveat is beach sand is full of salt which is extremely detrimental to both steel and concrete. I watched them do that on the beach near Tulum, Mexico.
Or the commentator did say there were at least 20 Israeli's missing. It did look like a clumsy controlled demolition.
They say they are searching for survivors... so, this doesn't look like it was planned.. (publicly)
Forty year old condo building. Fifty something unaccounted for last I heard. One child recovered dead, a teenager found alive. They said building was being inspected for 40 year recertification in one article. Guess they were a day late.
so i heard some retired engineer tried to warn them about this, but since he wasn't a licensed structural engineer, fined him instead.
Damn.
The Hard Rock hotel partially collapsed while being built after a crane accident I think in New Orleans 2019.
Look how far the debris field stretches away from the building. It didn't fall down, it toppled over; rotating on the exterior edge. Look how far the roof remnant has been displaced. That might result from some kind of footing failure I'd guess.
The video pretty clearly shows that the structural failure was low, and pulled it down, and not the top failing first. I don't recall where, but I also read that parking was under the building, so there would be a lot of exposed support structure that could fail that is out of sight . . .

Surely they wouldn't have used beach sand, aka blow sand, in the concrete.
But the concrete does look crumbly. Beach sand isn't worth a sh*t for anything but beaches.
Looks to me like the roof is on the highest part of the rubble and the balconies are to the left of that picture. Truly a tragic event!!
Beach sand is a lot of dead sea animals........organics not as solid as rock debris.
There are discusions going on now from people that have come foreward saying as late as the mid 90's there were structural concerns with this build due to sinking and cracks in the concrete.
Im sure they are very busy now in CYA mode and working up gag orders.

I dont think so since they woukd have rolled in with force on full display before killing a bunch of people.
I'm putting my money on subsurface soil (or lack thereof) failure.

Im putting my money on negligence from city inspectors and the property owner ignoring the signs of imminent danger.
They said only one dead - no way, has to be more. Very sad. Imagine thinking how cool it is to have a sea-side condo...then this. Serious prayers out to the injured and families of the dead or missing.

obviously there are more, that was just the one they were reporting at the time. Agree with the rest of your post.
The building was completed in 1981….so it had been there a long while. Been through a lot of storms, etc.
I’d wager that the deep foundations were compromised by sub-surface water…..essentially washing away the soil.
There is a metric-ass load of dead load on those foundations. If water started to compromise the soil beneath it, it got to a tipping point and down she came.
We’ve been involved on construction projects adjacent to the beach (not in Miami, but definitely in south Florida) that were nowhere near the size/height of that building and the deep foundations can go way, way, way down below grade.
Terrible situation. Unfortunately, there are going to be a lot more dead bodies pulled from that collapse. You can bet your bottom dollar all of the adjacent buildings will be under very comprehensive inspections if it was a deep foundation failure due to soil disruption. Scary stuff.
