I would think judging by the pictures, also I am no structural engineer, I would imagine that they may install the 8 outer super columns next then work on tying the first floor together to form the second. I have done a few mock models of buildings, (one using Super Columns, one using a central core.) Both of those being a project for my nieces drafting class. (One of the first projects one ever brought to me I enjoyed doing LOL) Sure not as complex as The One. The mock models were cardboard and popsicle sticks. She is considering Architecture as her career.
