Swire, overseeing Sunday\u2019s 8:30 a.m. demolition, says in an implosion, \u201cdust is released in a matter of seconds.\u201d So, any dust clouds will form quicker but also dissipate quicker.<\/p>\n
The developer notes dust could linger in the general area for \u201cseveral minutes,\u201d but that also depends on wind conditions. Wind speed and direction will determine how far dust reaches.<\/p>\n
Swire says that it\u2019s made efforts to mitigate the impact of dust on residences and businesses in the area. That includes remove concrete walls and drywall. Hazardous materials have also been removed from the building. And air quality monitors will be installed to measure conditions post-implosion.<\/p>\n
In addition to dust, here\u2019s what else to expect:<\/p>\n
Road and bridge shutdowns<\/p>\n
Miami police say they will shut down several streets before the 8:30 a.m. Sunday implosion:<\/p>\n
Bridge: The Brickell Key Bridge will be closed to traffic and pedestrians at 7 a.m. Sunday.Brickell Avenue: Eastbound traffic at Brickell Avenue and Eighth Street will be blocked.Brickell Bay Drive: All traffic on Brickell Bay Drive will be routed west to Eighth Street.Reopening: The cleanup process of the 23-story building and six-story parking garage is expected to end by 1:30 p.m. The bridge, streets and sidewalks will then reopen.Vibrations<\/p>\n
Lower levels: In an implosion, the entire structure doesn\u2019t collapse simultaneously as one unit. That means \u201cany resulting vibrations are expected to be well below the allowable statutory levels set by relevant authorities,\u201d according to Swire. \u201cAnd accordingly, no damage is expected for neighboring structures as a result of such vibrations.\u201d<\/p>\n
Debris<\/p>\n
Precautions: Broken or fractured debris will strike the ground for several seconds, according to Swire. \u201cIt is expected that resulting debris will remain within the footprint of the building.\u201d Swire is still taking precautions. The demolition team plans to keep some walls of the parking garage intact \u201cto help contain the debris.\u201d It\u2019ll also place temporary barges in the water next to the site to catch any debris that falls into the Biscayne Bay. Since hazardous materials have been removed from the building, Swire says any debris that lands in the water shouldn\u2019t be harmful.<\/p>\n
Dust cloud<\/p>\n
Even as the organizers say they don\u2019t expect dangers from the implosion, they do give warnings about dust for nearby residents and businesses:<\/p>\n
Exhaust: All exhaust systems should be turned off.<\/p>\n
Elevators and stairs: Elevator and stairwell doors should be closed to reduce any chimney effect, which occurs when stairwells and elevator shafts draw air in at the base and exhaust it out of the top of the building.<\/p>\n
Intakes: Ground-level exterior intakes should be covered with Geotextile fabric and weighed down with sandbags.<\/p>\n
Pools: Pools vulnerable to dust can be covered with poly sheeting. To keep the poly from taking on water and sinking, use pool balls and blow-up rafts to support the poly. Then use sandbags around the outside edge of the pool to hold the poly in place. Resident access to the pool should be closed while it is covered since falling into a pool covered with poly could be dangerous.<\/p>\n
Smoke alarms: Smoke detectors should be in test mode. These detectors can\u2019t tell the difference between smoke and dust.<\/p>\n
Restaurants: Businesses should make sure there are no gaps around doors or windows and that exhaust fans on hoods are turned off.<\/p>\n
