www.pedestrians.org Part 10. Demolition of the old AOL Headquarters in Ashburn, Virginia. Produced by John Z Wetmore, producer of "Perils For Pedestrians".
I have seen it done; a headache ball on a steel-frame building in downtown Columbia in Maryland. Berg was the contractor. The building had bolt and gusset connections between the columns and beams, so the crane operator had to hit the beams right at the connections to shear them off the columns. The problem with steel frame buildings is that the steel members that are loosened from columns is that they then act as springs that absorb the energy of the ball. Occasionally a man with an oxycetalene cutting torch would go up on a manlift to pre-cut columns. A high-reach demolition excavator with a shear might have been more effective on that particular job, but the crane operator was a skilled operator, and the job got done. It's a case of "you run what what you brung."
The guy in the small ecavator and the double-t-beam has probbably the bigger balls to try this wrecking with such a small machine on this massive struckture ;-)

Ракету сбросить у России попросите. В одну секунду останется лежать груда металла.
Contractor is too tight to use explosives to do a proper job.
