The framing process is remarkably quick with panelized construction.  As you can see from the photo examples, the first floor is erected in a single day by a small team of workers.  Since Ryland sells many copies of their floor plans in different communities, they can built most of the frame in house at their factory and the end result is a sturdy, well constructed and easy to assemble structure.    The crews utilize pneumatic nail guns to quickly bind all of the materials together.  Each section of the first floor frame fits together well and you get an immediate idea of the actual, physical layout of the house.  The interior walls are also panels that are secured to the floor and the exterior walls in rapid fashion.  The 2x4 construction for this floor plan features nine foot walls, as well as numerous windows, all cut out of the OSB and headed with the joists.
