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.

While placing concrete on the 7th floor of a new hotel in Houston, TX, 16 construction workers were suddenly sent falling to the 6th floor below, sending 9 of them to the hospital, according to local news reports.
As a storm blew through the Dallas, Texas area on Sunday afternoon, a tower crane standing near an occupied apartment building collapsed causing at least one fatality and 6 injuries.
Completed in 1976, the CN Tower in Toronto, Canada held the record for the tallest freestanding structure in the world from 1975-2007, until it was supplanted by Dubai’s Burj Khalifa. At its highest point, the CN Tower, which is mainly used as a communications and observation tower, reaches 1,815.4 feet (533.33m). Last year, the tower underwent a $16 million renovation and Priestly Demolition shared a fascinating, in-depth video for how they took care of the demolition of the interior space and walls.
Cranes collapsing on-site are serious business, especially since many of them resulted in the loss of life. A recent crane collapse on a construction site in Alpharetta, GA was caught on camera after it caught fire, but luckily no one was injured.
There are a lot of different specialty construction contracting sectors within the industry and cruise ships are definitely one of them. There are plenty of unique challenges when dealing with a moving ship versus a static building. A recent accident highlighted the challenges when a crane collapsed on a cruise ship under renovations, injuring 8 people.
Demolitions by implosion can be fun to watch when they go right – or wrong – but nearby residents can be greatly affected by the high powered blasts and huge clouds of debris that follow. A few years ago, a botched demolition in England left dozens of nearby residents unable to return to their homes for several days. Last week, an obsolete Steel Basic Oxygen Plant in Weirton, West Virginia is leaving residents in a similar situation.
Over the years, Liebherr, the German Crane Manufacturer, has given us some absolutely amazing videos. For example, they put on a show for their best customers one year and lifted one crane with another crane, which was lifted by a third crane, which was then lifted by a fourth crane. Another video highlighted the 58 cranes that were on site at the same time at the world’s largest airport build in Istanbul. Well, the company is back at it again, this time on top of Europe’s new tallest building.
