Chinese construction firm Broad Sustainable Building has found a way to build structures at incredible speeds. Having already constructed a 30-storey building in just 15 days, the developer decided to one-up itself by creating a 19-day build period for a building that was almost twice the size.
Talk about having your work cut out for you.
The building was originally supposed to dethrone Dubai’s Burj Khalifa to become the tallest structure in the world at 220 stories, but its proximity to an airport raised concerns among local officials. That’s why the “19-day” part of the developer’s claim can be a little misleading. Work on the building actually had to be halted for about a year once concerns over the airport were raised, but the delays were never about the construction itself.
So what’s the secret to this company’s efficiency? The key lies in the way it prepares for jobs. Large sections of the buildings are completed before they ever see a job site, meaning they simply need to be stacked on top of each other once they’re finally carted over.
The developer says these approaches greatly reduce the amount of trips needed to transport the raw materials, slashing about 15,000 truck journeys from this project alone. In fact, the building was constructed with China’s pollution problems in mind, using quadruple-thick glass and tight “99.9 per cent sealed” construction. The air in the building is supposedly 100 times cleaner than outside.
The completed structure contains 800 apartments and enough office space for 4,000 people. Which is pretty impressive, when you consider it took less than a month’s worth of work to finish.
At the same time though, you have to wonder how safe it could be with all that rushing going on. That’s why we’ll be keeping one eye firmly on this:
