Demolition of the Metrodome will begin again Sunday morning, but this time, "controlled explosive charges" will bring down the structure's remaining roof structure.
Work was halted Monday after a ring beam unexpectedly fell out of sequence in the Dome's demolition, bringing the teardown to a halt. No one was injured and all debris fell within the demolition safety zone, so no passersby were at risk of injury, according to general contractor Mortenson Construction.
After consulting with structural and demolition experts this week, it was determined that the safest way to bring down the remaining portion of the ring beam is with the controlled explosives, the Minnesota Sports Facilties Authority said in a statement. The MSFA is the public body in charge of stadium construction.
The demo will occur 7:30 a.m. Sunday, with the concrete ring beam demolished in a manner similar to the way the Metrodome's roof cables were severed.
"Neighbors should be aware that there will be vibration, dust, and noise associated with the ignition of the charges and the demolition of the ring beam," the MSFA said in a statement.
There will be a number of road closures in the area to create a safety perimeter for the demo, the MSFA said. Along with 11th Av., Fourth, Fifth, and Sixth streets and Chicago Av. (Kirby Puckett Place) will be closed beginning at 5:30 a.m. and will remain closed until an "all clear" signal has been given. That should be no later than 9 a.m., the MSFA said.
The Downtown East light-rail station will be closed during this timeframe, as well. MetroTransit buses will serve as alternate transportation to shuttle passengers between stations adjacent to the Metrodome.
No public access will be permitted within 250 feet of the Metrodome.
