How the Kingdome might look as it falls
Thursday, March 9, 2000
How the Kingdome might look as it collapses, according to artist renderings released by Controlled Demolition Inc., the company that is engineering the explosives for the dome's March 26 implosion:
Invisible divisions
Phase one
Phase two
Reduced to rubble
The dome will be "divided" into two three-wedge sections (highlighted above in yellow) that will collapse in two phases.
Explosives will detonate in the roof and columns of the first collection of wedges, triggering the collapse sequence.
Seconds later, the same process will be repeated along the remaining wedges, with additional explosives fracturing the structure.
After roughly 17 seconds, the dome will have collapsed onto a "cushion" of preset concrete placed to absorb the impact.
