We have an excellent subcontractor roster, and they perform the majority of the work on our sites. My grandfather used to build 90% of a home with his own crews. Today this is impractical. The training, insurance, and licensure requirements alone dictate this. The process is also too detailed and specialized to expect generalists to perform the way we need them to. We employ six very skilled artisans. They mainly do radiant flooring, decks, ICF block construction, timber frame raising, light excavation, material handling, clean up, and specialty carpentry.
