[TowerTalk] Pad and Pier Foundations

[Kelly Johnson]

Yes, they probably use a back hoe.  I suspect the answer to my
original question about how they build the pad-and-pier holes is that
they dig the hole big enough for the pad, insert a form for the pier,
pour the pad and pier, wait for them to dry, then backfill.  My
original question really was: is backfilling OK for these types of
foundations?  All foundations I had seen in the past required
"undisturbed soil" around the foundation.  I couldn't see how this
could be accomplished for this type of foundation.  I guess
backfilling for this type of foundation is not only OK, but probably
the only practical way of doing it.
