How big is the root ball on a hardy hibiscus? Concrete work tomorrow

I am having an antique wrought iron gate installed tomorrow.
It weighs well over a hundred pounds, probably
a good deal more. It will be fixed in position to 2, 1” steel pipes set in the
concrete. It’s going right in the center of my front yard garden as a
centerpiece. Smaller perennials will be moved out of the way, but I want my
hardy hibiscus to stay where it is. I had knee
surgery 2 weeks ago, so it will not be me doing the digging. He said he would
dig out what was necessary. The installer gardens himself so knows how to dig
things out without destroying them, but there is really no other good location
for this hibiscus.

The person who is doing the concrete work says the holes should
be no wider than a foot at most, smaller if we can get a narrow hole deeper.
Due to the weight, deeper is better, wide doesn’t help that much. He will be digging
the hole with an auger (hand, not powered).

The hibiscus is 'Kopper King.' It was planted in June of 2014. When purchased it was in a
pot at least a foot wide, probably larger. I don’t know how old that would make
it. I want to know how close I can safely plot this hole, to the hibiscus without damaging or killing
it. Thanks!
