Must be a bit of confusion or mis understanding but our site work tends to be more in the shop fitting sector as oppose to construction sector. And there is very very high standards of workmanship in this area z(
I'm more on about the shop fitting sector as oppose to the construction sector. Fit out companies we work for seem to have extremely high standards as they do a substantial amount of repeat business for blue chip companies on the high street.
New stud walls constructed with tin (no bends) plumbed by lasers built by multi skilled tradesmen. In my eyes if it's not acceptable it doesn't get tiled!. Because as soon as you put a tile on its your responsibility!.
Don't get me wrong it's not alway like that but a lot of the time it is.
I can agree with the shop fitting side of what you are saying I was working for shop fitting company's for years and I was even a partner in one for 10 years doing Next stores. Bruntwood office fit outs. Grosvenor group etc, but like all things there are bad ones out there and shopfits have a short shelf life to especially the larger companies.
