Wood Framed Assemblies Demolition (cont.) Typical costs for demolition of wood framed structural assemblies using hand tools when a building is being remodeled, repaired or rehabilitated but not completely demolished. Costs include removal of type NM non-metallic (Romex) cable as necessary, protecting adjacent areas and normal clean-up. Costs do not include temporary shoring to support structural elements above or adjacent to the work area, loading, hauling, dump fees or salvage value. Costs shown are per in-place square foot (SF) of area being demolished. Normal center to center spacing (12" thru 24" OC) is assumed. Figures in parentheses give the approximate “loose” volume and weight of the materials (volume after being demolished and weight.)
