You may remember Priestly Demolition Inc. from a few other videos of theirs that we’ve shared in the past. They take a lot of time and effort to put together some exciting and informative videos of their demolition projects each year.
Priestly recently knocked down and cleaned up the 340 foot long, 62 foot wide Victoria Street Bridge in 20 hours, which was amazingly 9 hours ahead of schedule. The road was closed on 5am on a Saturday morning and opened by 1am on Sunday. A total of 10 excavators were used, in tandem, to strategically rip art the structure.
Over 3,300 tons of debris was removed from the site, which required about 300 truck loads over the 20 hours. I’m always amazed by the coordination of these demolitions. There are so many moving parts and the trucking schedule is so important to staying on schedule. Priestly is no stranger to performing these types of demolitions, but this is the first one I’ve seen of theirs where there are excavators working on top the bridge and on the sides at the same time, at least for part of the job.
Check out the video of the demolition below!
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.
As we’ve seen in the past, demolitions aren’t all about implosions. There are still many manual demolitions that are carried out by skilled excavator operators. The Victoria Street Bridge in Ontario, Canada is a recent example of that.
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.
A couple weeks ago, JP Morgan Chase announced that they planned to demolish their existing 52-story Manhattan headquarters, which is believed to be the tallest voluntary demolition in history, in order to build a 70 story, 2.5 million square foot building in its place. The move left preservationists upset at the idea of scrapping the nearly 60 year old building and others wondering how exactly they were going to safely demolish a building that tall in such a congested and busy area.
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.
