So much for the ''Approved Contractor'' Status that's being banded about, as being the bee's knees of the industry!! lol!!
Electrical installation work above false ceilings should be signed off as being complete (along with any other services work eg ''ceiling closure certificate'') before any false ceiling are errected on any half decent project/contract. As you say, that would have been the Clerk of Works responsibility to head an inspection team with all the associated contractors/sub-contractors on the small to smaller medium projects/contracts....
Have the Clerk of Works disappeared altogether now then??
Not come across any what you would call 'proper 'uns' in the last ten to fifteen years. All local authority work used to come under the scrutiny of an engineer who knew his particular field. Within that period I've had young lads or lasses, from behind desks, making occasional visits to site and asking how things are progressing rather than insisting on standards being met. I have had some who knew the building game, in a general sense, but, as an example, remember one fella in charge of a job, asking my advice on electrical principles whilst preparing for course exams. Probably never even had a screwdriver in his hand....except at the christmas do, that is.
