Tom:
I was in Virginia about 10 years ago presenting a seminar to the inspection department in Chesterfield County, and some of the inspectors there say they made as many as 40 or more inspections per day.
That may be possible, if you count multifamily dwelling units and multiple meters, etc., so they add up.
I agree with you, that 4-6 inspections on large jobs, like malls, high rise, and industrial sites will take the time needed. The best bet is when you are sure about the work of the installers.
I can tell a short story here, I found a GEC stubbed into each end of an existing conduit for about two feet, and when I pulled it out of each end --- the guy almost fainted!
