The "Cube Cut" demolition method (quake-proof, quiet, quick and block-by-block de molition method) has been developed by Obayashi Corporation. In this method, the building structure (columns, beams and flooring) is cut into blocks, which are then lowered to ground level where they are pro cessed into smaller blocks and are separated (refer to Fig. 1 and Photo 1). Because crush ers are not used on the top floor, pieces of crushed concrete are not scattered about and noise, vibration and soot/dust are effectively suppressed, making this an eco-friendly de molition method.
