Cranes collapse for a variety of different reasons. Some are overloaded, some catch on fire, and others succumb to high wind loads. Regardless of the reason, a falling crane can cause tons of damage and have the potential to kill on-site workers and pedestrians walking near the job site.
A recent crawler crane collapse in Northern Italy could have been much worse as the crane, carrying a large section of viaduct, crashed to the ground. Workers on both sides of the crane began to run as you could hear several others screaming as the crane began to tip. According to Vertikal, no injuries were reported. That includes the operator, who they report was able to jump from the crane before it collapsed.
There are two videos of the incident below. The first, by Storyful News, starts as the crane begins to fall. The second, by Mi Li, shows a full minute prior to the collapse. At the 1:20 mark of the second video, you can actually see someone narrowly escaping from just underneath the crane, which some are assuming was the operator.

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.
There are a lot of people that would be pretty unhappy with whoever tears down a 98 foot tall, 105 year old tree to make room for a building expansion. In order for most projects to work financially, however, many trees are uprooted and replaced with smaller trees. That’s not what happened with what is believed to be the state of Idaho’s largest sequoia tree, however.
As recently highlighted by several multi-story building fires, contractors should always be prepared in the event a fire starts on a job site. There have been dozens multi-story building fires in the past few years and many were started when the building was topped out. In most cases, the project was completely destroyed, leaving developers and owners to deal with years of delays from insurance claims. A massive five-alarm fire at an Oakland construction site is one of the more recent examples.
Two construction workers in Sarasota, Florida were recently trapped 15 stories in the air after one of the lines on their suspended scaffolding snapped. One of the two men was able to be pulled to safety by some co-workers on site, but the second was stuck on the scaffold for an hour before the fire department could rescue him.
