There’s no easier way to make thousands of people mad then to screw up traffic for an extended period of time. Road construction can also be extremely dangerous for road crews working throughout the world. It seems like I read a story about a construction worker killed by a motorist every single day, so whatever it takes to lower that number can only be a good thing.
Modular and pre-fabricated construction is growing popularity on the commercial and residential side of the industry, put it may be even more so on the infrastructure end, and for good reason. By completing major portions of the work off-site, the existing conditions are only affected for a minimal amount of time. In the video below, you’ll see a 230 feet long tunnel (70m) be installed under a highway overpass in just 3 days. The existing overpass had to be demolished and re-built in that same time period, as well. That’s not something that can be accomplished with a traditional cast-in-place method. With the tunnel already built, it merely had to be pushed into place.
The tunnel spanned under the A12 highway in the Netherlands, which heads towards Arnhem. Dutch construction company Hejimans performed the job through an impressive thunderstorm, as well, which is shown towards the end of the video. This isn’t the first highway overpass to be removed and replaced in one weekend either, just last year a Chinese construction company removed and replaced a very large overpass in just 43 hours.

Construction Junkie has shared a lot of demolition videos. Typically, people line up waiting for the moment when the building explodes with their eyes peeled and cameras ready, just waiting for the perfect video. This video, however, is much different.
Doing something in the name of revenge typically is never a good idea. Concrete truck operators getting involved with that revenge is probably an even worse idea. But, anger makes people do weird things, including video taping said revenge.
As harmless as it looks, dirt can be one of the biggest hazards on any construction site. It’s heavy and is bound to collapse without warning unless proper safety measures are taken into account. Landslides are essentially no different than trench collapses, without proper shoring or sloping, you could be putting worker’s lives in danger.
Nobody likes having something stolen from them, obviously, but some people are also more willing to go to extreme lengths to get their items back. Construction sites are hot targets for thieves, because there’s typically thousands of dollars worth of tools and material on site at any time. On one construction site in Dallas, an alleged thief thought he was going to snag a tool from the site and drive away safely, but several construction workers had a different thought in mind.
Other than at the zoo, there aren’t many options for Americans to come into contact with a rhino. It’s also becoming increasingly rarer to come into contact with them in their native countries. Black rhino populations, like other rhino species, have fallen drastically since 1970. Savetherhino.org estimates that in 1970, there were around 70,000 black rhinos in Africa, but now there are only around 5,000.
Remote sites have extreme challenges, like finding enough staff to work the jobs and being able to get materials to the site. Large mining operations have turned to self-driving dump trucks, like this 320 Ton mega machine, for a few years now. But, Lockheed Martin, a giant in the world of global security and aerospace, has a different solution for remote sites.
Early this year, a landslide caused catastrophic failure to the Pfeiffer Canyon Bridge along California’s famous Highway 1. California Transit officials closed the bridge on February 21st and announced it would be demolished and replaced. Time is of the essence as US News reports that over 400 residents are stranded on one side of the bridge and helicopters have had to bring in food for them. The residents are still able to use the footpaths in the area to cross the canyon.
If you’re into heights, then China may be the place you need to be. The country recently unveiled the world’s highest and longest glass bridge and, as scary as many tourists may find that, it was way more dangerous while it was under construction. New footage of another construction site in the Laowang Monutains is giving that bridge a run for it’s money.
There’s no doubt that bridge demolitions by implosion are extremely fun to watch, but the fireworks show and big splash into the water below can sometimes overshadow other demolition projects that don’t allow implosion. Priestly Demolition Inc. (PDI) recently won two 2016 World Demolition Awards for one of those projects where implosion was not an option and they have also produced an incredibly detailed video of how they did it.
Since Construction Junkie was conceived in 2015, we’ve seen a lot of construction equipment flip for some really stupid reasons. Like this crane, this other crane, and this third crane dropping a bulldozer. Those are just some of the ones caught on video and they should be enough to convince you not to go out of your way to do dangerous things with a crane.
