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.
As the crews weakened the base of the building, they used an excavator to break down the final supports, causing the building to fall. What they didn’t plan for was for the building to fall on top of them. The worker who caught the collapse on camera was concerned for the safety of the worker inside the excavator.
Nashville News Channel 5 decided to investigate the job site after they got ahold of the video and the Tennessee branch of OSHA followed closely behind to also conduct an investigation. “The images of this building demolition raise serious concerns for the assistant commissioner regarding the safety of workers at that site,” TN OSHA spokesperson Chris Cannon told News Channel 5.
Tripping or tipping, is a common way to bring down a building, but it has to be done with caution to make sure the structure falls the correct way. Much like a lumberjack would bring down a tree, the building supports are strategically weakened in specific areas to tell the building where to land. Based upon the results of this demolition, it would be safe to say something went wrong.
It’s currently unknown whether or not the operator was injured by the collapse, but there are rumors that may have been taken to the hospital to be checked out. As we learned from another demolition involving tripping that resulted in a 2.6 million pound smoke stack falling on an excavator, staying inside the cab is usually the safest place to be if something stats to fall on top of you.
I started the video, loaded to YouTube by Dean Graves, at the 1:25 mark to reduce some of the lead up to the collapse.

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.
Demolitions by implosion can be fun to watch when they go right – or wrong – but nearby residents can be greatly affected by the high powered blasts and huge clouds of debris that follow. A few years ago, a botched demolition in England left dozens of nearby residents unable to return to their homes for several days. Last week, an obsolete Steel Basic Oxygen Plant in Weirton, West Virginia is leaving residents in a similar situation.
Over the years, Liebherr, the German Crane Manufacturer, has given us some absolutely amazing videos. For example, they put on a show for their best customers one year and lifted one crane with another crane, which was lifted by a third crane, which was then lifted by a fourth crane. Another video highlighted the 58 cranes that were on site at the same time at the world’s largest airport build in Istanbul. Well, the company is back at it again, this time on top of Europe’s new tallest building.
