Smoke stack demolitions are always fun to watch because they typically stand much taller than the buildings surrounding them, giving cameras great views of the carnage. They don’t always go well, like when a 2.6 million pound brick stack fell directly on top of an excavator (the operator was fine, by the way), but they’re always dramatic.
Both smoke stacks at the Sappi Paper Mill in Muskegon, Michigan were supposed to be demolished at the same time, but plans changed after one required an emergency demolition due to its poor condition. To add to the interest, the crumbling smoke stack was also glazed with a material that contained 2 to 3 percent asbestos, according to MLive.
Because the asbestos could not be abated before the demolition, extra precautions had to be taken. Not only was the building and surrounding area continuously sprayed with water before and after the initial implosion, but the stack was directed towards a pond of water, all to reduce the amount of airborne dust. Members of the Michigan Department of Environmental Quality (DEQ) were also on-site to monitor the air quality inside a 1,000 foot perimeter set up around the stack.
All of the estimated 685 cubic feet of debris had to be wrapped and transported to a landfill in Coopersville, Michigan. Soil testing will also be carried out by the DEQ to determine if any soil needs removed. As for the second smoke stack, asbestos will be abated prior to that demolition, which is expected to happen in the fall.
The video below was captured by a 4K camera by the City of Muskegon for your viewing pleasure. I chose to start the video at 1:30 in, as the implosion and collapse happens soon after.

The most popular method of demolition these days is by implosion, but not always welcome in certain areas or situations. The use of explosives can greatly damage neighboring buildings and spread hazardous materials over a large radius, which is why a cooling tower at the Mülheim-Kärlich power plant in Germany had to be slowly dismantled from the top.
After causing devastation in the Bahamas, Hurricane Dorian worked its way up the U.S. East Coast last week and eventually made its way up to Nova Scotia, Canada as a Category 2 storm. The storm left more than 369,000 without power in the Canadian Region, according to CBC, but also caused a tower crane to buckle and collapse in the city of Halifax.
While placing concrete on the 7th floor of a new hotel in Houston, TX, 16 construction workers were suddenly sent falling to the 6th floor below, sending 9 of them to the hospital, according to local news reports.
As a storm blew through the Dallas, Texas area on Sunday afternoon, a tower crane standing near an occupied apartment building collapsed causing at least one fatality and 6 injuries.
Completed in 1976, the CN Tower in Toronto, Canada held the record for the tallest freestanding structure in the world from 1975-2007, until it was supplanted by Dubai’s Burj Khalifa. At its highest point, the CN Tower, which is mainly used as a communications and observation tower, reaches 1,815.4 feet (533.33m). Last year, the tower underwent a $16 million renovation and Priestly Demolition shared a fascinating, in-depth video for how they took care of the demolition of the interior space and walls.
Cranes collapsing on-site are serious business, especially since many of them resulted in the loss of life. A recent crane collapse on a construction site in Alpharetta, GA was caught on camera after it caught fire, but luckily no one was injured.
There are a lot of different specialty construction contracting sectors within the industry and cruise ships are definitely one of them. There are plenty of unique challenges when dealing with a moving ship versus a static building. A recent accident highlighted the challenges when a crane collapsed on a cruise ship under renovations, injuring 8 people.
