Okay, it even kicked the pros asses. The landlord/architect said...'well, that slab might be 4 - 4.5" thick.' Try on 6" (or more) for size. Our whole day cutting to 4.5" thick was for naught, because the BIG jackhammer couldn't break up the last 1.5" worth a damn.
It took the pros 3 hours to get this much out before calling it a day to come back later with the big saw to recut it.
Another pic for artistic sake.
I called it a day, and went for a ride!
