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.
Earlier this week, a rowhouse, which was occupied by a laundromat, in Baltimore, Maryland was mistakenly destroyed as demolition crews were working on tearing down the building next to it, according to the Baltimore Sun. Thankfully, no one was injured, as police occupied the area the night before demolition to keep people away.
The building that was supposed to be demolished had developed a large crack, estimated at several inches at its widest, and one of its exterior walls had started to bow. After city inspectors determined the building was unstable, an emergency demolition was ordered.
The owner of the mistakenly demolished building was actually across the street watching the demolition, but told the Baltimore Sun that he’ll rebuild the property. He had recently purchased the building and planned to convert it into a single family home.
Around the 50 second mark in the video below, you can see a section of brick fall over onto the neighboring property, which completely annihilates it. It makes you wonder how stable that building actually was if it was destroyed so easily.

Hurricane Irma ripped through the Caribbean and landed in South Florida a little over a week ago, sadly killing at least 50 people in Florida and causing plenty of property damage. High winds that accompanied the storm also caused the collapse of 3 construction cranes – two in Miami and one more in Fort Lauderdale. The crane in Fort Lauderdale was recently dismantled and the action was caught on video.
As if the high winds and heavy rains weren’t enough of a safety hazard for the people of Florida, citizens who are staying in the area also need to be concerned about the dozens of tower cranes that are still erected throughout downtown.
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.
If this video of construction worker’s chasing down an alleged tool thief and hanging onto the hood of his car wasn’t enough to convince you to not mess with construction worker’s things, then maybe this new video will be. Construction worker’s tools and trucks are their livelihoods, and they don’t take too kindly to people who don’t understand that.
Directional boring, or horizontal directional drilling, is a common method for installing underground pipe and conduits, among others. Its main benefit is that it minimally disturbs the areas around where your pipe or cable needs to be installed. Instead of cutting concrete, asphalt, or ripping up landscaping, the boring machine digs a tunnel underground and the installing material slides in after it’s complete.
That’s what it’s SUPPOSED to do anyway.
You may remember a story we shared at the end of June about a rescue of a construction worker who was dangling from a suspended scaffold 15 stories in the air. The Sarasota County Fire Department completed a very skilled rescue, in which one firefighter scaled down the side of the building to the trapped worker, attached him to a harness, and both men were hoisted back up to the roof. The cause of that failure was a snapped line. At that time, the fire chief mentioned that he rarely sees events like this and that only 5 or 6 rescues like this have happened in his 29 year career.
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.
