Chimney stacks once lined many city skylines across America and Europe and became extremely popular during the 1800’s Industrial Revolution, which began the shift from hand made products to machine made. Also known as flue-gas stacks, the chimneys are used as an exhaust method for industrial furnaces, steam boilers, and other similar heat and smoke producers. The concept of the flue-gas stack was developed in the mid-1600s, before the concept expanded some 200 years later.
As American and European industries have started to move away from industrial manufacturing, many chimney stacks have begun to be demolished for new development. Last year, two Scottish power station chimneys were demolished simultaneously in a video that made our list of best demolition videos of 2015. The current tallest chimney in the world is in Kazakhstan, standing at 1377 feet (419.7m) and was built in 1987, the United Kingdom’s second largest chimney used to be the Chimney of Grain Power Station, before a week ago. Built in 1979, the Grain Power Station Chimney stood 801 feet tall (244m) in Kent, England and weighed approximately 44,000 tons (40,000 tonnes). The power station that it accompanied was closed in 2012, in order to make use of a new onsite gas-fired power station.
You can check out some incredible drone footage, shot by Luke Sanders, of the demolition that turned the chimney into a big dust pile below:

New demolition videos are always fun to watch. You know what’s even better, though? A bunch of demolitions all at once.
While being prepared for demolition, the Grand Avenue Bridge in Glenwood Springs, Colorado unexpectedly collapsed to the railroad tracks below. Thankfully, no injuries were reported, but the local police chief said that workers had to flee the scene once the bridge section started to fall.
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.
Buildings are demolished all the time in order to make way for new construction. The buildings that are demolished have usually lived out their useful life and are no longer functional. Recently a demolition video resurfaced, which shows a 27 story building in China being imploded. The strange thing is that, since it was finished in 1999, the building had never even been used.
A nearby office worker caught video of a dramatic demolition that showed the remains of an 11 story building collapse on top of the excavator performing the demolition.
In order to get the bad taste of last week’s botched demolition, in which an adjacent building also got destroyed in the process, we needed to share a highly successful one. Priestly Demolition, a Canadian demolition contractor, has been the subject of our articles in the past and the company has even won awards for the best demolition in the world.
Mistakes during demolitions happen. Sometimes contractors knock down the wrong buildings, other times the explosives used don’t knock the building over, and other demolitions are carried out with a complete lack of regard for human life. As fun as they are to perform and watch, they’re inherently dangerous and there should be a plan in place in case things go wrong.
Construction Junkie has shared a lot of demolition videos. Typically, people line up waiting for the moment when the building explodes with their eyes peeled and cameras ready, just waiting for the perfect video. This video, however, is much different.
Early this year, a landslide caused catastrophic failure to the Pfeiffer Canyon Bridge along California’s famous Highway 1. California Transit officials closed the bridge on February 21st and announced it would be demolished and replaced. Time is of the essence as US News reports that over 400 residents are stranded on one side of the bridge and helicopters have had to bring in food for them. The residents are still able to use the footpaths in the area to cross the canyon.
There’s no doubt that bridge demolitions by implosion are extremely fun to watch, but the fireworks show and big splash into the water below can sometimes overshadow other demolition projects that don’t allow implosion. Priestly Demolition Inc. (PDI) recently won two 2016 World Demolition Awards for one of those projects where implosion was not an option and they have also produced an incredibly detailed video of how they did it.
