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.

Remote jobsites with difficult terrain pose some substantial logistical challenges when it comes to getting equipment and materials on site. I’ve seen several different methods used in the past, such as heavy equipment carrying blimps, cargo planes, helicopters, and the Fat Truck, but I recently came across a new method: a cable car.
In November of last year, the 546 foot tall Mina Plaza in Abu Dhabi officially broke the world record for tallest demolition by explosion, supplanting Hudson Department Store in Detroit, Michigan, which held the record for 22 years.
If you need to get some heavy mechanical equipment on the roof of your project, you could use a boring old crane – or you could gas up the bird and make that equipment take literal flight. Alright, so cranes aren’t actually boring, but some times a helicopter makes more logistical sense, either because it reduces total lift time or, in some cases, makes economical sense. Either way, there are some important safety precautions to take in case something goes wrong.
2020 was a stressful year, so let’s decompress a little bit by reviewing some of the most fun demolition videos from the past year. A demolition that broke a 22 year old record highlights the bunch and I also stretch what the definition of “demolition” is a little bit, because I think the video is so cool. Don’t @ me.
Without further ado, here are the top 7 demolition videos from 2020:
2 years ago, crane manufacturer, Sarens, unveiled what is considered to be the world’s largest crane, by both size and lifting capacity. Big Carl, as the huge crane was nicknamed, began work a few months later on the Hinkley Point C nuclear power station in England. Now, the jobsite boasts an abundance of crane activity, a true site to behold, and it was captured on aerial footage for you to enjoy.
Back in 1998, the Hudson Department Store in downtown Detroit, Michigan was demolished by explosives. That building stood 410 feet tall across its 29 floors, making it, at the time, the tallest building to ever be taken down by implosion. The dust cloud covered many city blocks and the 20,000 unsuspecting people that came to watch the event. That record was just recently broken by a building over 100 feet taller than it.
Excavators aren’t typically meant to be dropped down to a lower level, but certain circumstances require it sometimes. The machines are obviously extremely heavy, so a large crane and proper rigging is required for it to happen safely. As a construction firm in Hong Kong, China recently found out, though, it’s a little tougher than it seems.
Usually, when a new development is going to go into a spot where a building already exists, that existing building gets blown into smithereens and its remaining rubble hauled away. BUT, there is apparently a different way to handle the situation now, which is by politely asking the building to walk away and to find a new home – well, kind of.
CAT is no stranger to finding extremely creative and expensive ways to show off their construction equipment. In years past, they’ve created a giant Jenga game with 600 pound blocks and the world’s first moving golf course on the backs of their dump trucks. Now, they’re showing off some of their new technology with the release of the biggest PAC-MAN game you’ve ever seen.
On Tuesday morning, February 23, the Syracuse Fire Department responded to a call about a collapsed crane on a construction site near the university. Thankfully, no injuries were reported.
