Has anybody heard if this is a normal engineering practice published anywhere, or did he just think this up himself?
i have never heard of over exing a footing to fill it back and compact it so its the same as an engineered pad but i found out later that the engineer who detailed the house was in training so i figure he was just to smart on paper for his own good
architects and engineers make me laugh cause they make these extensive details and then tell the owner its nothing to put an rv garage in the side of that mountain and then you tell the owner to dig out do pad and backfill the walls for his garage will be over 50 thousand just in dirt work and they always say well the architect said it wouldnt take much.
az has a lot of issues with expansive soil especially if the pad company screws up so all track houses now are built as post tension slabs to eliminate settling. but there were some big class actions over the years do to expansive soil so engineers tend to overcompensate witch has cost unfathomable amounts of money over the years. we dug footings on a school were half the footing were in solid rock and the other half were in the fill zone of the pad. the footings in the fill zone had to be excavated to natural and filled back with abc all the way to bottom of footing there were spots that were 13 feet deep 4 foot wide and filled back to just 2 foot deep.
all that so there was no chance of liability for settling. what did that cost?
