The implosion: pushing the button
The implosion will take place in two phases, collapsing the Dome in six sections.
Explosives in three sections will be detonated, followed several seconds later
by detonations in the remaining three sections. Detonation will begin when an
electric pulse is sent through two wires encircling the Dome, setting off six
electric charges. The charges will ignite the network of orange detonation cords
that will burn up instantaneously in a bright flash lighting the fuses to the
explosives. Timed groups of explosives will then go off at different intervals.
Gravity takes over
After the implosion
Of the initial 130,000 tons of material that made up the Dome, 80,000 tons were recycled onsite or hauled away before the implosion. Of the remaining 50,000 tons, most of which will be concrete, 35 percent will be used onsite as backfill for the new stadium. The rest will be sold as recyclable material.
