Yikes, I hope you aren't digging it by hand!   Better hurry up and hope you don't hit rock!  

(I have a rock layer here at 40" down.)


As for your original question, I find it amazing how requirements have changed since I got my license (1963).   Look around at all the towers standing for 30 years and I'll bet they don't have high strength concrete and complex rebar.   They just won't last....   ;-)     Seriously, I put up a 64' freestanding Heights tower twice in 1970 and 1975 and hand mixed the concrete (two days on the first one using Sackrete) and it only needed a 4x4x4 base back then with a TA-33 tribander and other antennas on it.   

I do think the lawyers have changed the engineering specs over the years.

Good luck digging,
