Florida’s Atlantic Coast is a very corrosive environment. Post-tension cables give way all of the time if not properly done. I lived in a building where one let go and it burst through the concrete slab at points like a sine wave. And it was like a thunder-clap. I don’t know how many would have to let go to facilitate a collapse. I would not be surprised to learn this was the cause.
Is it possible that someone accidentally cut some post-tension cables and that’s what caused the collapse?
I worked const for Rooney on many of Galt Ocean Drive condos in Ft laud from 74 on.
