Can the World’s Tallest Building Be Built in 90 Days?

Hello everyone, I hope y’all are doing well.  Today, I want to talk about an article I found a while back.  In the article, the construction company building the next building slated to be the tallest building world claims that they will do it by the end of 2013.

At first, I thought this was not possible at all.  However, the company, Broad Sustainable Building, has previously built a 30 story apartment building in 15 days.  Apparently, the plan will be to prefabricate as much as they can off site in the 4 months before on site construction starts.  Since they just got their permit this June that means they should be done with that by the end of September.  This leaves them 3 months to do the on site construction if they want to finish in 2013.  According the article, the plan is to build five stories of the building each day.  Along with the quick construction time, the skyscraper will only cost $628 million; half the cost of Burj Khalifa.

However, as cool as this sounds, I have some skepticism about how this can be done and so does the author.  A 30 story apartment building has far fewer critical design issues than 220 story skyscraper.  In the article, Head of Structures for WSP Middle East, Bart Leclercq, believes that they will run into issues with the required use of on site concrete work which provides the extra stiffness needed.   In order to safely construct the building, adequate curing times are needed which would be hard to manage with the fast pace of construction.  The other concern that crossed my mind even though it wasn’t stated in the article is this – what will be done about inspections and oversight?  If a building is being erected this quickly, a lot of oversight and coordination will be required and I could see a lot of mistakes being made as rushed as the process would be.  What is your opinion on this project?  Do you think that this building schedule is attainable?  What about safety and risk in regards to the building schedule?  Thanks for reading and have a good weekend.
