Is the contractor "building" the new house.........or just having his guys put together all the parts?
The contractor is just a check pusher, most don't do chit but pay laborers.
That's why they are just called GC's anymore.
He has an excavator come in and dig it.
Has a Mason or concrete crew lay the foundation.
Has a framing crew frame it.
Has an electrician wire it.
Has a plumber plumb it.
Has a roofer roof it.
Has a window and door contractor install windows and doors.
Has a siding crew side it, or gets the Mason back to brick it or put lick'n stick stone on it.
Has a flooring contractor put floors in.
Has a cabinet crew set cabinets, sometimes those are custom built by some real craftsmen, but that's pretty rare anymore, and they go by cabinet makers, not builders.
Then gets a landscape crew to finish the outside.
The GC is really just a ringmaster of a circus.
