any of you out there in TT Land been required to install a  Ufer ground?
What's the best way to bond the pigtails to the  rebar?

    There was a real good post here at some point  that pointed out the 
problems with trying to weld rebar. I think they  mentioned brazing it but I 
be wrong. You might check the archives or  maybe someone has saved it.

    Umm, didn't you mention that that's what Rohn  says in their specs? 
(Hint: It is.)
    My question is: why would you use a form? Most  tower base holes come in 
many shapes and sizes - one with perfectly formed  sides is the exception. 
Even if the sides of the hole have sloughed, just fill  the hole with concrete 
no muss, no fuss with forms and you're conforming to  the manufacturer's 
specs. Sounds pretty straightforward to me.

I'm not sure what you mean. Please explain. 

>  Third question: Has anyone out there been required to  connect the rebar in
the anchor pads to the ground system?
    No. I've never been involved in one like that in  WA or CA in a couple of 
dozen tower construction projects.
