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:
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.
