[TowerTalk] rohn 45 foundation interpretation

[Steve Sala]

I am putting in 90 feet of Rohn 45.  My hole will be per the Rohn dimensions on drawing C610621.  I am confused on the rebar situation that they show.  Of course, they are covering 15 different sized foundations with this same drawing.  

1. Do I really use rebar for my CB2 hole?  If so, what are the lateral ties shown?  Are they rebar or wire?  I presume they hold the four vertical rebar pieces rigid?  If that is there only purpose, could I not just push the four vertical pieces into the wet concrete afterwards, making sure I got at least 3 inches below the concrete surface and did not come out the bottom? 

 2. Since the drawing also covers the foundation for Rohn 25, I never heard of anyone putting rebar into a 25 hole around this area.  Could someone please clarify this for me. 

3. Below the 4 foot level bottom of the hole, how much more do I have to dig to put gravel for drainage?  I have a pile of 5/8" minus I use for filling in the driveway holes that I would use.
