of the Georgia Dome was intended to begin shortly after the stadium's final event; however, due to construction delays caused by the complexity of Mercedes-Benz Stadium's eight-panel retractable roof, demolition of the Georgia Dome was postponed until the new stadium's certificate of occupancy could be issued. GWCCA officials stated that the Georgia Dome would remain nominally operational until Mercedes-Benz Stadium was ready; however, the Dome's artificial turf had been removed and its offices vacated prior to the announcement of the new stadium's delay. On June 9, 2017, Steve Cannon, CEO of the Falcons' parent company AMB Group, stated that construction officials were confident that Mercedes-Benz Stadium would be ready in time for the Falcons' first preseason game, and the process of decommissioning the Georgia Dome had resumed, with the Dome scheduled for implosion on November 20, 2017 at 7:30 am EST. In July 2017, GWCCA officials removed equipment they intend to reuse either at Mercedes-Benz Stadium or elsewhere on the GWCC campus while other equipment was liquidated by sealed bids. Most of the seats in the lower and middle bowls were sold in bulk to high schools and colleges while pairs were sold to individuals; most of the upper bowl seats were recycled. The stadium's lower bowl and loading docks were demolished by mid-August. From September 16 to 30, 2017, memorabilia from the Georgia Dome was sold in an online auction format by Schneider Industries. Demolition officials from Adamo Demolition, the company contracted for the job, stated that the pressure from the implosion needed to go up from the roof and not out through the sides to ensure that Mercedes-Benz Stadium and other nearby buildings were not damaged during the demolition; to protect nearby structures, construction felt was placed over the four corners of the Dome, and a tall fence covered in the same material was erected between the Dome and Mercedes-Benz Stadium. To ensure that the roof fell in place during the implosion, parts of the concrete ring supporting the roof had been chipped away and ventilation holes were cut into the roof fabric. of explosives were used to bring the Dome down within 12 seconds. Due to the large exclusion zone required for the demolition, no public viewing areas were made available; additionally, Metropolitan Atlanta Rapid Transit Authority officials announced that rail service west of the Five Points station would be suspended on the day of demolition until
