Thanks for the info - Sounds like a lot of stuff needed to be ripped out, even if it wasn't concrete. Strange, what would it be if not concrete? Rebar goes in concrete...
Son of a 40 year Concrete foreman here and I have poured my own share of it. (Re)inforcing (Bar) is the steal rods in-bedded in Concrete to give it additional tensile strength.
If they couldn't core drill the holes for the pucks without hitting the rebar then someone f'd up. Either the plans didn't leave a gap in the rebar pattern for the core drill (patterns can be very dense depending upon the floor load), the gap was installed in the wrong place by the construction crew, or Disney messed up in plotting the locations for the gaps. You CAN NOT drill through rebar when core drilling. Bad structural things can happen if the rebar is severed. I once needed a core drilled in a mechanical room in a high rise office building for additional network cabling, but they couldn't find a big enough spot in the room for the 6" core when they x-rayed the floor. The pattern was too dense. We had to switch to the other mechanical room for the riser cable installation.
I suspect this might be a case of semantics and to the degree of effort.
I could see them having to jack hammer around where they need the pucks to get at the rebar and then redesign the pattern at that spot and pour new concrete. Some might call this minor work while others might describe it as having the whole concrete floor ripped out.
As to the bumpy unload area, they could use a concrete grinder and level the floor in that area, replace the whole section or maybe skim coat it. Either way, very messy and time consuming. That sounds like the laborer running the concrete float was at fault.
So you can see why some people would call this "having the floor ripped out" while others in the trades, would not.
Also, factor in that the concrete will need time to cure to full strength depending upon the recipe so no running heavy ride vehicles for testing over it until its cured.
Now that I think about it, part of the reason why Florida's version didn't need the floor worked on could also be due to the differences in the building codes between CA and FL. CA has different requirements due earthquake resistance. I could see where CA building codes could require a denser rebar grid due to seismic movements that Florida doesn't.
