I had a plasterer/builder walk off a job, with the customers approval.
I turned up to address to do 2nd fix the single storey flat roof'd extension & found plasterer still on site skimming the old part of the house.
Customer starts asking (before I even get inside the place) "you did put in all the cables long enough at the socket locations didn't you. Have you a plan of where the lights were to go";\
Should have been standard plaster straight on to blockwork........but in his infenite wisdom went down the drylining route (not a problem in itself, but I'd checked before I did the first fix what the wall finnish was to be).
Goes in only to find
1) cables cut short in back boxes.
2) Back boxes sealed in behind drylining.
3) 2" gap between back boxes & plasterboard (he'd used battens to fix drylining to wall? rater than boxing in just the pipes in a corner he stood the whole wall off them).
4) gaps around back boxes where board had been cut to large, accessories fell through the hole.
5) All 20 odd downlight tails hidden away behind 150mm of celotex & plasterboard (when I did finaly locate a tail I discovered he'd folded the tails back & looped them behind the clipped cable run along the joist "to make it easier to fit the celotex")
Called the plasterer/builder in & he said "thats how I always do it & it's upto the electrician to get over the problems of finding cables & stuff"
Dont think so mate & this is a rough estimate you'll need to be paying for rectification to the works.
After much effing & jeffing he was helpped off the jobROTFWL
