All,
Rebar should not be welded at any time. This will affect the
material properties of the rebar and will invalidate any calculations for
the structural integrity of the rebar cage. Rebar must be tied with metal
wire to specific twists and length. If you want a ground at your tower.
Buy some 8ft ground rods and drive them in. Or, install ground radials.
But, please don't weld the cage. Your inspector will thank you and you will
save money by not building it again.
v/r,
Joe

If your going to use the cage for a Ufer ground, then it should be welded.
If your not, then tied would be fine. The 100,000's of feet of rebar in a
bridge is tied.

I am under the impression that the rebar cage should be tied, not welded.
Comments?
