I can't believe how many times I've posted some degree of an argument to this thread!
I agree, I do think **part of it is real** and part of it is fake
And no, it was not cut halfway from the top down then bottom up.
A hole like this would **normally** be drilled with a core drill which would
have more then 3" of travel which can have bits that are 12"+ in depth.
It's also an interesting thing to watch. I was on a job site where they were
cutting 8" slab about the size of an elevator shaft. As they cut the slabs in about
2' widths, it would drop down onto the next floor!
After the first few floors, the general contractor asked the slab cutting company
to support the slab while cutting and not to drop it to the next floor...
