A lot of my job involves warranty work.
I see all the "little nasties" that are done by the crews. When I report these to the company, they are noted, more vigorously when it's cost the company $$$. Often these are passed on to the crews with a warning not to do it again. More often than not, the guys in the field ignore them (Have you ever heard "That's the way we always do it?").
Unfortunately, many inspectors here in SoCA either have so little time to inspect, are lazy slackers, or just don't have enough Code knowledge to properly inspect the jobs and these practices continue.
(Although not quite as bad as some that you describe.)
so the vicious cycle goes on...and on...and on. [Linked Image] S
