Flooring system is shown in place under what will be the dining room. Flashing on wood is a termite shield. Flashing is galvanized steel. All joists are hung with Simpson Strong Tie hangers.  Perimeter/Band Joist is comprised of three 2x10's.  Central girder is also comprised of three 2x10's.  Blocking is my preferred way of laterally bracing floor joists.  Sub floor, where you see my compressor resting, is 3/4-inch CDX plywood.  On top of CDX will be placed tar roofing paper and then old tough & groove flooring will be reinstalled.
