Another interesting (logical) thing - the outward appearance of the supercolumns doesn't change - but it will actually get thinner (less depth on the side facing the building) as you go up.
I only see three nodes in the Walters group lot, plus the one on-site makes four. I assume, like others have mentioned, that the nodes attach to the angled columns at the temporary supports. From there, horizontal beams would run between the nodes and the supercolumns, creating a hashtag pattern ( # ).
Oh, that would account the the extra ones I'm counting at the factory sight. Okays, this is starting to make sense again...They are in groups of two, stacked against each other. Only 4 may be needed for the first floor but similar structures are needed for floor 2.
