Re: Cowboys
Unfortunately this isn't an isolated case.
Go to any newbuilds and you can see where the brickies changed during the build. The builders use the best(time served)to set out the foundations nice and true, up to dpc, these brickies then move onto the next plot.
Along come another gang to build up from there, then the foreman realises their not that clever and fires them off site, along come another gang, only slightly better than the previous and so it goes on. This is the downside to using Unknown sub-contractors.
I've been on sites where you can visibly tell there's been two or three different gangs working on the same plot, totally different standards of quality.
