Looking at the design, I’ve never seen anything like it. It’s a large concrete footing on top of four concrete pillars. At first my thought was that that they were trying to make it easier to finish the building at the end of the job. Normally you would pull the tower sections out, then go back and fill in the 3×3 meter holes in the floors that allowed the crane through. But if you had four concrete pillars close together like that, what could you put in that area of the building?
The process ended up taking a total of 15 8 hour days to assemble. The crane was brand new and out of the box. If you’ve ever assembled a brand new crane, you know how many parts we are talking about and the time to locate each bolt and washer. It’s IKEA on steroids and from Hell.
