UM/R / skyscraper demolition system

How can a skyscraper be dismanteled?-The task is the same as drilling a tunnel, but from top to bottom, between other skyscapers and at unlimited traffic. Crushing-robots, equipped with cutting-torches and pneumatic-hammers are positioned in a way, that the swivelling-ranges of their arms overlap the whole floor area, removing one floor after another. Through ducts, hanging outside the building, the overburden is transorted down to the ground, where it is shreddered and sorted.
UM/R provides a reliable mean of making the life in megacities bearable again, which is nowadays characterized by narrowness, stress and smog.
