Reno:
I have to take exception with your comments.
I have to start out with 'back in the days', as I am not an EC now.
For 20+ years, one of the large property mgt firms used all the same subs on all the commercial projects, and we ALL worked as a team to provide a quality tenant fit-up. It all went smooth and it was rare to have any 'battles', and rare to have anyone 'screw' another. It worked well at most other jobs with the same team.
That said, yes when a sub was brought in by the tenant (data/voice, whatever) there was potential for issues. Good job mgt. keeps projects running smooth and on schedule.
As to the issue of 'work after inspection'...I can tell you unless it is 'done' after 'final', the odds of being discovered are not slim if all the inspectors work as a team.
Now keep in mind I was 95% commercial EC, and really hated resi.
