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.

It’s a tale (tail) as old as time: a horse walks into a construction trench, gets stuck, has to be lifted out of it by a helicopter. The trench didn’t appear to be that deep, so I don’t think OSHA is going to need to get involved with this one.
For the third time in a year, construction workers have had to be rescued while dangling mid-air by fire rescue teams in Southern Florida. Last year, there were two incidents in Sarasota, Florida that involved failed suspended scaffolding in as many months. Just last week, another incident in Palmetto Bay required the Fire Department to intervene.
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.
Crane collapses on construction jobsites are usually pretty terrifying, especially when the jobsite is full of workers. A construction site in St. Petersburg, Florida got extremely lucky when a large construction crane collapsed and narrowly missed several running workers.
This video is a bit of a throwback, but I recently came across it on the interwebs for the first time and thought it was worth a share.
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.
Last Thursday, every construction professional’s worst nightmare happened. Lives were lost, both construction workers and civilians, by way of the catastrophic collapse of FIU’s under construction pedestrian bridge. We shared what we knew as of late Thursday night, but since this is not only a tragedy directly related to construction, but also a huge learning opportunity for the entire industry, I wanted to make sure we continued to follow and update on the story as it develops.
Terrible tragedy struck Florida International University’s (FIU) campus yesterday when a newly installed pedestrian bridge collapsed onto the road below, killing at least 4 and severely injuring many more.
It’s pretty amazing the work that can get done when a lot of resources and money are thrown at one project. Past examples of this include a gigantic sinkhole that was repaired in Japan in just under a week, the complete emergency rebuild of Atlanta’s I-85 overpass that was completed a month ahead of schedule, and this video of 116 excavators working side by side to demolish a 1,640 foot long overpass overnight.
When anyone sees a hard hat, they typically immediate associate it with construction. It’s the ultimate symbol of safety on the job site. We all know we should wear them, but it’s easy to get annoyed with the minor inconvenience that they cause and forget about the extreme consequences that could result if a falling object catches us when we aren’t wearing one.
