I also mark the floor where boxes and recessed lites are located. To help safeguard against the rotozip I try to carefully fold my wires as far as possible towards the back of the box, but even this does not always guarantee against nicked and cut wires. I have also been taking digital pics on bigger jobs.
I spend a bit of time "chisling" out plaster.

The bottom line is sheetrockers and plasterers get paid by the square foot. They are rewarded for speed and we do suffer because of it.
