For the kind of work you are talking about, I would definitely hire subs. For bigger project, like additions, a GC isn’t such a bad idea. I do my own GC for bigger projects but I don’t think I’m really saving any money. I do it because I don’t have to manage an architect and a GC to get things done exactly the way I want. I lose time doing it and I probably incur delays and I probably pay the subs more than a GC, too.

GC Downsides:
– GC’s charge a margin.
– GC has to translate my needs to the subs.
– Unscrupulous GCs know how to work you over.

GC Upside:
– GCs pay less to the subs than I do.
– Saves me time.
– Scheduling can be difficult on your own.
– GCs deal with inspectors.
