What is a Turn-Key build:
When building an estimate of costs there are many variables in what each customer expects a turn-key is. Normally, a turn-key build is one where the general contractor takes the build from a set of plans his customer gives him. He will then have a surveyor stake the corners of the home and hire an excavator to dig the foundation. He will then hire a foundation group to pour the foundation. A framing crew will then come in and frame the home In the case of a log home the framing crew will lay the floor. A stack crew will then erect the log shell. The contractor will then hire a roofing crew, and the framers will install the windows and doors. Your contractor will then bring in plumbers. electricians, and HVAC people to do the dry-in portion of the build. At this point in the build, this is called a "dry-in".
Finish: Your contractor will then bring in a finish crew to install the finishes as to plan. Bring back the plumbers, electricians, and HVAC people to do the finish on the trades, like cabinets, sinks, furnaces. The home will have the final inspection, and the building dept will give you an occupancy permit. You can then move in.
