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.

Multiple buildings imploded at the same time with multiple different camera views? Sounds like the making of a great demolition video.
A construction crane that was working on a highway widening project in St. Martin Parish in Louisiana collapsed onto the adjacent roadway last week, injuring one driver.
Demolition by implosion videos are always fun to watch. Adding an element of water makes them even more dramatic, though it’s probably not great for the ecosystem. Late last week, a one mile long, 23 year-old bridge in China was imploded in front of a crowd of spectators and caught on camera.
Cranes are an extremely useful and important piece of equipment on the majority of construction sites. They can also be extremely dangerous if they are not understood or respected.
As the US is experiencing our own natural disaster, by way of Hurricane Florence, China is being hit badly by a Typhoon Mangkhut. According to Independent, the storm has caused a crane, which was being used on a 22-story housing development, to crumble. That collapse was caught on camera by neighbors.
There have been a few devastating structural collapses across America and the world this year. In March, an under construction pedestrian bridge collapsed in Florida, killing 6. In Colombia, ten workers were killed when a large section of a bridge being built collapsed. Both of those tragedies happened while the structures were still being built, but a recent collapse in Texas has a bit of a different story.
If you’re a general contractor in the Davie, Florida area, I have an idea why one of your deliveries might have been late last week.
On Monday morning, a 13 story building in Miami Beach that was being prepped for demolition suddenly collapsed, injuring one Project Manager that was struck by debris.
