re: contiguous pour, there is an interesting
case study (PDF) of the construction of a Trump building in Chicago.
Thank you very much for that! I am an engineer (or was, well, I guess still am, P.E. still valid), come from sort of that neck of the woods, love good stories about engineering projects, but living in New England the last 30 years, really don't have a clue about building projects going on, anywhere, unless they make big news or are brought to my attention.
Looking at that tower, finished, it is hard to figure out how and why it gets the distinction of being the largest concrete building in the US. Dig into the construction details - fascinating.
Thank you again.
