[TowerTalk] what is 'circular tie' as is used in a towers concrete base?

[StellarCAT]

thanks for all the comments.... it does seem like the foundation drawing they have appears to be more for pier pin than when a section is in the mix. I’d think a section would provide tremendous ... connectivity (?) to the concrete. In the past I’ve just slid in some straight pieces of re-bar to extend out into the rest of the pour. But I’m concerned that without a ‘formal’ drawing (for the inspector) I’m stuck with building this large rebar cage system even WITH a tower section in there. The second tower, the larger of the two is rotating so the rotation hardware goes on top so I will use/need the rebar they show. Hopefully they (again – the inspector) don’t mind making it a square and not a circle as that seems easier to me (use a cutoff wheel to cut the back of it allowing it to cleanly bend at the needed corners).
