A video of ongoing demolition of a skyscraper in Tokyo makes it look like a shrinking building and it goes viral. It was reported that the Taisei Corp, the construction company is taking down the Grand Prince Hotel Akasaka and is using a unique and new demolition technique. This technique which is very eco-friendly because the demolition starts from the top to bottom is pulling down each floor and incredibly that no dust and no mess procedure.
The demolition workers were using the top floors of the building as workspace supported by temporary columns that are lowered by jacks as each floor is removed. There is a crane on the inside of the building which works to deconstruct each floor. “It’s kind of like having a disassembly factory on top of the building and putting a big hat there, and then the building shrinks from the top,” a Taisei rep told Japanese art and design blog Spoon & Tamago.
According to the blog that this new demolition method reduces construction noise by 25 percent and creates 90 percent less dust than the typical wrecking ball or implosion methods so it is not risky for people near the skyscraper. It is very energy-efficient and the crane moves debris, it generates electricity that powers other equipment, making it a clean-energy project.
As today, the hotel has been lowered around 100 feet, and it will continue to shrink until it reaches ground level. Due to extensive renovation, the Grand Prince Hotel Akasaka was slated for demolition and closed in early 2011, but was reopened as house for the victims of Japanese earthquake and Tsunami of the same year.
