            Wood Framing Demolition. Typical costs for demolition of wood frame structural components using
            hand tools. Normal center-to-center spacing (12" thru 24" OC) is assumed. Includes breaking materials
            into manageable pieces with hand tools and handling debris to a trash bin on site. Costs include
            removal of 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. (Add for
            demolition of flooring, roofing, sheathing, etc.) Figures in parentheses give the approximate “loose”
            volume and weight of the materials after being demolished.

            Ceiling joist demolition. Per in-place SF of ceiling area removed.
