Contact with overhead power lines is a major hazard when working on most construction sites and especially when working from elevated platforms or with heavy machinery.
Between 2008 and 2010, 119 fatalities in the construction industry were caused by contact with overhead powerlines, averaging to about 40 per year, according to The Center for Construction Research and Training. It was also the cause of over half of all fatalities caused by electrocution for non-electricians.
When working from ladders, scaffolds, lifts, or in cranes and other heavy equipment, a minimum of 10 foot clearance should be kept from a high voltage power line providing 300 volts to 50kV. For any voltages over 50kV, 10 feet plus 0.4 inches for each additional kV should be the minimal distance to the line.
A video was recently shared on Facebook by Glen Cook showing the huge amount of power that an arcing powerline can create, backed by huge balls of fire which nearly swallow an entire tree. This could be a great example to show to your teams at your next toolbox talk.
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.
As you may already know, the NBA’s Milwaukee Bucks officially opened their new home, the Fiserv Forum, for the 2018-2019 NBA season last October. That new stadium is being heralded as the “World’s First Bird Friendly Arena,” due to many of the design features. Well, since the new one is open, we can only expect that the old, non-bird friendly (I’m assuming) arena has overstayed its welcome and has to go.
Let’s get 2019 started with the first building demolition by implosion of the year.
The Smithsonian channel is airing a series of shows titled America in Color, in which they enhance lost or forgotten video footage of the 1900s, beginning with the 1920s. Part of the first episode in the series shows the men that worked on skyscrapers in New York City and it’s been edited to show color, as opposed to black and white, for the first time.
Everyone has a camera in their pocket these days and when something goes down on the jobsite, you can bet it’s going to be captured on video one way or another. That can either be a great thing for marketing or an awful way to showcase your business.
