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!
Demolition by implosion videos are always fun to watch. Adding an element of water makes them even more dramatic, though it’s probably not great for the ecosystem. Late last week, a one mile long, 23 year-old bridge in China was imploded in front of a crowd of spectators and caught on camera.
On Monday morning, a 13 story building in Miami Beach that was being prepped for demolition suddenly collapsed, injuring one Project Manager that was struck by debris.
In January of 2018, ten construction workers were killed and another eight were injured when a bridge spanning the Chirajara canyon in Columbia partially collapsed. That collapse has since been blamed on a poor design, reports have stated. Last week, the remaining sections of the bridge were demolished in dramatic fashion.
A couple weeks ago, we shared a list of the 100 tallest buildings to ever be demolished. One of the most interesting things that I learned while researching for that article was that although Detroit’s Greater Department Hudson Store was not the tallest building on the list (it was #21), it was the tallest on the list to actually be imploded.
In February, JP Morgan Chased announced their plans to demolish their current 52-story headquarters located in Manhattan. Turns out, when that demolition is complete, it will also break the record for the tallest building ever voluntarily demolished.
One thing’s for sure, the only thing better than one structure being demolished is two structures being demolished at the same time. Late last week, a decommissioned Florida Power Plant saw to the implosion of two 462 feet tall cooling towers in spectacular fashion.
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.
