Horible how does a building just collapse without help
Warm humid air...over decades...can cause concrete to deteriorate.
The building had been sinking slowly since the 1990s.

Contractors have been known to cut corners. For example, specs call for iron reinforcing bars to be spaced 12 inches apart in the concrete. The contractor places them 18 inches apart instead, just to save a few bucks. No big deal, right? And no one will know anyway because the rebars will be covered with concrete.
I’m not saying that happened here. But it has happened.
The video I saw sure looked like an implosion, similar to when they implode old sports stadiums, etc...
Simple, Gravity is constant.
Any degradation of the Structure is amplified over time. This entire incident could go back to the very first Concrete pour when the Building was erected.
In this case, the Building Design, Engineering Methods and Soil Conditions will come under scrutiny as well as a forensic study of the original Construction Materials.
Since part of the Building remains standing, it will give them an opportunity to conduct a “before and after” study.
I will assume that this will be a wakeup call for thorough inspections of every High Rise Building in Florida and a slew of new Building Codes.
All that being said, may the Victims of this tragedy Rest in Peace.
