Yes, there is a chance of that happening.  Futhermore, if you are in an area
governed by the UBC or ACI 318 setting of reinforcement after the concrete
is placed is forbidden by code (UBC 1907.5.1).

Subject: Drilled pier foundation


Drilled pier foundations have reinforcement (vertical
bars + ties or spirals) in the upper few feet of the
piers. Recently, I heard that it is common for the
construction folks to place the pier concrete and then
push a preassembled cage of reinforcement through the
concrete. Does this method guarantee that the rebar
can be placed reasonably close to the way it is
detailed on the drawing? Is'nt there a good chance
that the rebar may be bent and mangled?
