[TowerTalk] rebar cages

[Mike Gilmer - N2MG]

I'm erecting some Rohn tower and have been studying 
the rebar cage drawings which can be a bit cryptic.  
In particular I am looking at the CB-1 base drawing.  
It appears that they (Rohn) want four vertical #6 
rebars (one near each corner) with horizontal ties of 
#3 every 12 inches.

The drawing shows each horizontal tie as being one 
continuous piece of rebar wrapped around the 
verticals.  Is there a significant difference in the 
strengths of these two arrangements?  Looks to me that 
having separate bars would be far easier to construct 
although using them would likely yield a somewhat 
less stable cage - at least when out of the concrete.
