Wooooooooooooo. Thank you! Much appreciated. Been stalking this forum for a while waiting to post.
I also have an amateur question. As the building grows in height and cement is poured in the core, how does the wood and steel (?) framing raise? Is it hydraulic where once the cement has dried the workers press a button and push it up? Or is it something else?
