It's amazing the tangents this thread brings to mind ....
First, I think of a recent job, were 99% of the work had been done by an unlicensed guy, who had dropped out of the apprentice program half-way through. Oh, his work was quite neat and competent - but it was also clear just where his education stopped. Those parts of the job that involved topics taught later in the program .... controls, contactors, alarms, even troubleshooting the lighting .... he avoided. He had never learned those parts.
Then I think of an upcoming job, where the GC and I are having a bit of a disagreement as to the required electric. The GC has overlooked several required circuits, and has placed 6 hair dryers, four curling irons, and the cash register on the same circuit. Do you think the customer - a hair salon - will be happy if the GC has his way?
OK, so I'm better trained than the GC and the half-trained guy. How do I get this message through to customers? How do I put a value on my 'design judgement?' That's the business challenge I have to face.
