In less than 30 seconds, there was nothing left but a pile of rubble.
Early Saturday morning, demolition crews imploded the 12-story Hammond Exchange office building in Dunwoody to make way for at least two future office towers to be occupied by insurance giant State Farm.
Dunwoody Police blocked off several roads near Perimeter Mall to keep onlookers and others away from the blast site. A crowd of more than 100 gathered in field next to the main office of The Atlanta Journal-Constitution to watch the implosion, which left a cloud of dust over that lingered over the site after a quick succession of explosions that dropped the office building.
State Farm and developer KDC are developing the corporate campus, known as Park Center, adjacent to the Dunwoody MARTA station. The complex could one day house 10,000 workers.
The first tower opened last year.
