I can definitely understand the 3 way/ 4 way switch problems, especially if one guy (or worse, 2 guys roughing in the same circuit) is roughing in and someone else is trimming out.
The rest of it just looks like workmanship issues, especially #2.
Considering how cut-throat residential wiring can be in some areas, QC can be a real problem. It would be nice to see some numbers attached to those deficiencies to see how it stacks up against my callback experiance.
Few things are harder to put up with than the annoyance of a good example.
there were no fires that were not contained by the boxes.
!!!!! Care to elaborate on that?
I'm hard pressed to think of a situation where the OCPD wouldn't trip in time to prevent a fire even if contained by the boxes.
When I worked with an EC in Central Cali doing phase two of our apt. complex (What a great job that was, get up at 8:45, walk out my door and across the drive to the jobsite by 9am) we did over 150 units in four months with no "fires" of any kind. Did have some miscues, though. Mainly 3 way and kitchen knee wall circuit issues.
I actually got involved in some of the loose luminaire issues. I tend to blame the manufacturer. They have one in particular that I am not sure how even gets listed. It is a 4' horizontal pipe with 5 lamp holders, glass globes and it mounts in a standard octagon or pancake box in the center. The pancake is the worst. The hickey screws bottom out before they seat. In any case it is a 2' of lever on two 8-32 screws.
