Most tall buildings sink unless anchored into bedrock. 1mm/yr isn’t much. That means it sank about 1.5” since it was built in the 80s.
Older structures collapse “all the time”. Most of the time it’s because of lack of maintenance. Older reinforced concrete buildings in marine environments are especially susceptible because we didn’t use coated rebar back in the day. Concrete collects moisture, moisture rusts the bars. Steel expands when it rusts and spalls away the concrete covering it accelerating the process. Lack of maintenance can lead to a failure. Most buildings are also not designed to have redundant structures, so if one piece goes it adds a lateral or rotational load to the next piece. That next piece wasn’t designed for those loads, so it fails. So on and so forth all the way down.
I’m gonna pick my structural engineers brain on this tomorrow. See what he thinks.

I'm questioning everything as if THAT was already known to be a problem, you would think they would have been monitoring & seeing foundation / structural evidence someone can hopefully confirm. Hell, I don't even know if it's factual.
I'm just a skeptic the way it fell...I've see them try to blow up buildings with controlled explosives that failed compared to how this one came down like a stack of pancakes. The mayor certainly has his radar on!!

Pretty good video explaining the possibilities.
We forget the lessons of our fathers. Even the Old Testament says "something something don't build your house on sand something". It was an example, not an engineering principal, but still...
As I struggle to return my Dad's 1921 1903 to military configuration, its strange to hear a building built in the 80s called old.

This is interesting.
Sooooooooooo exactly what I said!? LOL
I guess my Structures professor should be proud! lol Again, not sure this is what caused it, but it could have.
Another thing I noticed is that the lower level of the building was elevated and ground level used for parking. I can't find any good photos but from the areals it looks like there is no impact protection for the columns. How many times has some half blind retiree hit one of those? It is Florida after all... God's waiting room. How much damage did those columns take over 40 years? I know countless structures have exposed columns around cars, but it's possible.

Watching that security camera video of it happening is creepy. The center collapses, while the right side sways just a little.....then also collapses. Those poor people in the second part no doubt heard and felt the first part crumble, felt the motion, then it went black.
The death toll is gonna be quite high. Kudos to those SAR folks out there, and RIP to those hapless people in that building.
