The World’s first Ferris Wheel was designed and built for the 1893 World’s Columbian Exposition in Chicago, IL in 1893 by George Washington Gale Ferris Jr. Since then, the wheels have been a staple of many state fairs across the United States and many other places throughout the World. Much like tall buildings, the past few years has shown us that having the tallest Ferris Wheel is a strong source of pride for a city or country. The current record holder for tallest Ferris Wheel is the High Roller in Las Vegas, Nevada, topping out at 550ft and opened in March of 2014. The record won’t last much longer as there are two Ferris Wheels currently under construction that will be taller: the Dubai Eye and the New York Wheel. The Dubai Eye, which is getting very close to completion, is planned to reach a staggering 850 feet tall (260 meters) and the New York Wheel is expected to peak at 630 feet tall (192m). The original wheel designed by Ferris Jr. topped out at 264 ft (80.4m).
Though the New York Wheel may not be the tallest in the World once it’s complete thanks to the massive Dubai Eye, it will still hold the United States record until the next competitor shows up. At 630 feet, it will surely give tourists and New Yorkers some excellent views of the iconic city. It also gives all of us construction nerds a chance to get a detailed look inside the construction process. In the video below, by silive.com, you’ll be able to see a continuous pour of more than 4,000 cubic yards of concrete across roughly 420 trucks. In addition to the concrete, the foundation has over 900 tons of steel reinforcement bars carefully placed throughout. That gigantic foundation will be expected to withstand the weight of two legs, which each weigh 110 tons on top of the weight of the wheel and the 1,440 person capacity. This project is being carried out by Gilbane Building Company and is expected to be completed in 2017.
Record breaking or not, this an impressive attraction. Enjoy the video below:
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.
