Unlike demolition, deconstruction requires finesse instead of shear force. Reusable items such as cabinets and flooring can lose their value if they are damaged during the salvage process. To recover a window, for example, workers must remove its interior and exterior trim, cut fasteners in the frame, extricate the window, and store it safely on site until it is transported to a salvage yard.
