How is a builder or anyone else for that matter going to know exactly where a 50mm hole location for the kitchen sink waste, is going to end up?
Could be left a bit or right a bit or higher or lower. Better to drill when minds have been made up.
Or are you suggesting that a builder should follow all the trades about, i.e. sparky (extractor ducts), plumber (svp, boiler flue etc) and kitchen fitter (sink wastes) and drill holes for them all......or, according to you Norcs, leave all these holes in their ideal places whilst he is building?
Whilst i agree that it is possible to build in a sleeve of 110mm pipe in some instances, it is not always practical or sensible. People/clients often change their minds about locations.
So, when a kitchen fitter, plumber or sparks prices to do a job, he then rings up a builder to come and drill some holes?
Are you having a giraffe?
