I did one reno on a kitchen just before Christmas and the rockers covered all the outlet boxes. I still make a drawing with measurements of all the installations and that saved the day for me that time. Once Christmas was over I made up new contract blanks that, in addition to the usual other stuff, contain the words (in bold letters):
"Any extra time to repair, replace or otherwise rework any damaged, covered or altered electrical work done by any person or entity other than this contractor after the preliminary rough-in has been completed will be added as an extra charge to this contract at a rate of $1000.00 per hour or part thereof or $10,000.00 per day or part thereof, whichever is higher."
(I leave the interpretation of what a part of a day is, up to the person signing the contract, but what it really means is that if it's going to take more than half a day to correct anything the $1000.00 hourly rate is out the window.)( My solicitors advice.)
I put in a similar provision dealing with the completion of the trim out to complete the work. (Receptacles, switches, light fixtures, DW's, GD's, etc.)
It's become part of the stuff I explain to each and every person before they sign the contract, with particular emphasis on their responsibility to carefully oversee the other contractors during their work. I had one GC complain that he couldn't be everywhere and watch everthing so I explained that I wouldn't supervise other trades either. He walked away but signed the contract later that day after having had time to think about things for a bit. I haven't had a problem with any other contractors work since. I've not had a single problem or negative comment with any HO about their responsibilities at all when they are doing the job as themselves being the GC.
By the way, I still make drawings and now take lots of photos too.
