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.

The most popular method of demolition these days is by implosion, but not always welcome in certain areas or situations. The use of explosives can greatly damage neighboring buildings and spread hazardous materials over a large radius, which is why a cooling tower at the Mülheim-Kärlich power plant in Germany had to be slowly dismantled from the top.
After causing devastation in the Bahamas, Hurricane Dorian worked its way up the U.S. East Coast last week and eventually made its way up to Nova Scotia, Canada as a Category 2 storm. The storm left more than 369,000 without power in the Canadian Region, according to CBC, but also caused a tower crane to buckle and collapse in the city of Halifax.
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.
