Last week, there was a giant hole in the middle of a Fukuoka, Japan street, spanning 98 feet long by 88 feet wide by 50 feet deep, due to underground subway work causing a sinkhole. Less than 7 days later, all the utility lines were repaired, the hole was filled, the asphalt laid, and the road is back open. It was a true testament to what a considerable amount of manpower and money can do in a short period of time.
Compare that timeline to the repair of the sinkhole that formed in Brooklyn, NY due to eroded utility lines in August of 2015 and your head might start to spin. The Brooklyn sinkhole also resulted in considerable work, requiring workers to dig 60 feet down, replace a 48 inch water main, reinforce and clean a 15-foot-wide sewer line, and install a new 15-inch sewer line and several 12-inch water lines, according to the Department of Environmental Projection. One YEAR later, in August of 2016, that sinkhole was finally covered and the street was reopened, according to the Sunset Park Patch.

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.
Construction crews were preparing to replace window glazing on the 47-story tall Wellhouse na Leninskom tower in Moscow, Russia, when a cable snapped just as the window was about to reach the top of the structure
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.
