ALOT ? That's too small of a word !
I've done a TON of research, reading, talking with people and I still have only touched the surface of what I need to know. I've been real lucky with subcontractors. I remember talking with my excavation sub and he kept looking at me strange because of the questions I was asking. He had to remind himself that I wasn't an experienced GC and needed things explained.
I've been lucky too with major issues. 1st was ledge during excevation. I had enough room on the property to move the house over 20ft versus spending 8K on blasting. The second was a few wrong designed trusses. My framer took care of fixing those.
I'm a stickler for quality and I'm upfront with the contractors on that.
The house is up, framed and siding is going on this week. I've done much of the electrial and plumbing work on my own. Rough inspection should be next week. I think I see the end in sight !!!
