There have been plenty of demolition failures in history, no matter how easy strapping a bunch of explosives to an empty building may seem. This demolition might just break the record for delayed collapse, however.
Two vacant high rise buildings in Seaforth, Merseyside, England were schedule for implosion on Sunday morning, but after several booms from the first round of explosives, both buildings still stood. Frighteningly, one of the buildings decided to collapse unexpectedly 2 hours later. It’s probably embarrassing for the company in charge of the demolition, but the nearby residents are feeling the brunt of the failure, as they cannot go back into their homes until the second building finally falls. Most were only anticipating a two hour event, so they were woefully unprepared for a long delay.
The second building, dubbed the Montgomery House, was still standing on Monday, even after a partial collapse around 3:00pm local time, a video of which was tweeted by a Liverpool News reporter. There’s some strong language in the video, so it’s not safe for work.
As of Tuesday evening, residents have still not been able to return to their homes, according to the Liverpool Echo, as the building is still partially standing. Many have been forced to stay with family or at nearby hotels until crews can finally knock the building down. Their plan is to bring it down in “phases,” and the company has vowed to make the affected residents as comfortable as possible with hotel accommodations, food, drinks, and other amenities. Even though there’s now a plan, there’s still not a clear timetable for the work to be completed.
For the most up-to-date information, the Liverpool Echo has some great coverage on the developments.
This year saw more videos with environmental considerations taken into account, especially over waterways. Instead of imploding entire bridges, the part that spanned over top of the waterway were manually removed. I've also grown an appreciation for in-depth footage of demolitions that occurred under some interesting conditions. Some of the videos below show some extreme creativity to overcome obstacles.
On Sunday, demolition contractors tried to bring down the upper portion of the Pontiac Silverdome, former home to the Detroit Lions, but several of the explosives didn’t ignite and the structure was still upright after the smoke cleared. After videos of the failed demolition were posted online, the internet had a field day.
The Pontiac Silverdome was the home to the NFL’s Detroit Lions from 1975-2001 and NBA’s Detroit Pistons from 1978-1988. After the Lions opened their new Stadium in 2002, the Silverdome was passed around several times before it closed for the last time in 2013. Earlier this year, the building was condemned and the first round of demolition by implosion was scheduled for Sunday, December 3.
Getting the perfect view of a major building demolition can get you millions of hits, or even better, shared by us right here on Construction Junkie. Have your video get epic-ly photobombed and you’ll get even more views and definitely shared by us.
I don’t think there is anyone in the construction industry that has a better marketing department than Priestly Demolition, a demolition specialty contractor based in Ontario, Canada. Their Youtube channel is filled with high quality demolition videos in the form of timelapse videos and even a 24 minute long, highly detailed video of a bridge demolition so impressive it won awards for best in the world. Implosion videos are a great source of entertainment in their own right, but the videos that Priestly put out are not only entertaining, but also great for education purposes.
For almost 80 years, the Old Kosciuszko Bridge connected Brooklyn and Queens in New York. Much like many other bridges its age, it is being replaced due to capacity issues and deterioration. When it was completed in 1939, it was built for 10,000 cars per day. Unfortunately for the people who needed to use that bridge that past few decades, around 180,000 cars used it.
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.
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.
