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.

It’s a tale (tail) as old as time: a horse walks into a construction trench, gets stuck, has to be lifted out of it by a helicopter. The trench didn’t appear to be that deep, so I don’t think OSHA is going to need to get involved with this one.
For the third time in a year, construction workers have had to be rescued while dangling mid-air by fire rescue teams in Southern Florida. Last year, there were two incidents in Sarasota, Florida that involved failed suspended scaffolding in as many months. Just last week, another incident in Palmetto Bay required the Fire Department to intervene.
Demolitions by implosion seems like the easiest way to knock down a structure, but there is so much preparation that goes into it that even the slightest mistake can have a huge impact. When smokestacks are demolished correctly, it can be a thing of beauty, like when these two silos in Scotland hit each other midair or when this asbestos filled stack was precisely demolished to fall into a pool of water. Things didn’t go so smoothly for demolition crews in Denmark last week, however.
Crane collapses on construction jobsites are usually pretty terrifying, especially when the jobsite is full of workers. A construction site in St. Petersburg, Florida got extremely lucky when a large construction crane collapsed and narrowly missed several running workers.
This video is a bit of a throwback, but I recently came across it on the interwebs for the first time and thought it was worth a share.
It’s been a while since we have shared a demolition video on Construction Junkie. We recently discussed a very high profile demolition project, the tallest voluntary demolition on record, which is schedule to start next year and how it is expected to happen, but no videos. Between the cold weather in most of the country and the general lack of interesting demolitions happening, it’s good to finally be back to feeling normal around here.
Last Thursday, every construction professional’s worst nightmare happened. Lives were lost, both construction workers and civilians, by way of the catastrophic collapse of FIU’s under construction pedestrian bridge. We shared what we knew as of late Thursday night, but since this is not only a tragedy directly related to construction, but also a huge learning opportunity for the entire industry, I wanted to make sure we continued to follow and update on the story as it develops.
Terrible tragedy struck Florida International University’s (FIU) campus yesterday when a newly installed pedestrian bridge collapsed onto the road below, killing at least 4 and severely injuring many more.
It’s pretty amazing the work that can get done when a lot of resources and money are thrown at one project. Past examples of this include a gigantic sinkhole that was repaired in Japan in just under a week, the complete emergency rebuild of Atlanta’s I-85 overpass that was completed a month ahead of schedule, and this video of 116 excavators working side by side to demolish a 1,640 foot long overpass overnight.
When anyone sees a hard hat, they typically immediate associate it with construction. It’s the ultimate symbol of safety on the job site. We all know we should wear them, but it’s easy to get annoyed with the minor inconvenience that they cause and forget about the extreme consequences that could result if a falling object catches us when we aren’t wearing one.
