In January of 2018, ten construction workers were killed and another eight were injured when a bridge spanning the Chirajara canyon in Colombia 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.
The cable-stayed bridge was supposed to span 1,463 feet across the 938 foot deep canyon before it collapsed. According to the Global Construction Review, the death count could have been much worse if not for a training session that was taking place off of the bridge that included another 180 workers.
It took over 200 pounds of explosives, almost 1000 feet of detonating cord, and 30 detonators to bring down the structure. There was a tower crane standing adjacent to the section of bridge that was imploded, which looked like it was made of rubber when it fell. I wasn’t able to find out why that crane was not removed from site before the demolition, but it may have been damaged during the collapse.
You can watch a video of the implosion below:
Everyone has a camera in their pocket these days and when something goes down on the jobsite, you can bet it’s going to be captured on video one way or another. That can either be a great thing for marketing or an awful way to showcase your business.
Look, you could mobilize on site the boring old way by loading your heavy equipment on the bed of a trailer and driving it to site, or you could take a note from the Bravo Company of the 37th Engineer Battalion of the United States and spice things up a bit.
“World’s Largest” is definitely a sought after goal, especially in the construction industry. Sarens, a crane rental, heavy lifting, and engineered transport company in Belgium, has recently released a supersized crane that is being regarded as the largest crane in the world, by both size and lifting capacity.
Multiple buildings imploded at the same time with multiple different camera views? Sounds like the making of a great demolition video.
A construction crane that was working on a highway widening project in St. Martin Parish in Louisiana collapsed onto the adjacent roadway last week, injuring one driver.
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.
Cranes are an extremely useful and important piece of equipment on the majority of construction sites. They can also be extremely dangerous if they are not understood or respected.
