Rick, I think you may be pouring more concrete than you need, if this 
base is not already in the ground.  I have put up two Rohn 25 towers 
using the 2' x 2' x 3' base dimensions shown in the Rohn instructions for 
the foldover tower.   For a 40 foot guyed tower, I think you can reduce 
your base concrete cost by 75% (1.78 yd -> .44 yd).

73, Drew
