There are a lot of people that would be pretty unhappy with whoever tears down a 98 foot tall, 105 year old tree to make room for a building expansion. In order for most projects to work financially, however, many trees are uprooted and replaced with smaller trees. That’s not what happened with what is believed to be the state of Idaho’s largest sequoia tree, however.
St. Luke’s Health System in Boise Idaho paid roughly $300,000 to relocate a sequoia tree that many view as a landmark, in order to make way for an expansion of their facility. It took roughly 10 hours for crews to move the 800,000 pound tree to its new location - about 2 blocks away – using a system of inflatable rollers, which look like something you’d buy a hot dog off of at a convenience store. Two excavators were used, in tandem, to pull the giant tree onto the next roller in line.
It was a pretty amazing process and the team in charge of moving the tree have given it a 95% chance of survival. There are three videos below of the process for you to check out. The first is a timelapse of the entire move, the second is a close up view of how the rollers were used, and the third shows how the tree was removed.
How the tree was removed
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.
