Larry,
Having installed a 70 ft self supporting tower in 4 parts of the US, and seeing
for myself the complex stresses
imposed on the base, I wouldn't deviate from the manufacturers' specifications.

Unless you are a Civil or Mechanical Engineer and can do all the calculations
to confirm that your redesign is
in fact "equivalent", I recommend you follow the manufacturer's design and
specs exactly.

Subject: [TowerTalk] Concrete base - tower
I am preparing to install a 70' Trylon SuperTitan S500. Nothing is done at this
stage...I'm thinking about
pouring the base first. Hi.
The manufacturer has supplied a drawing of the required concrete base. It is a
pad and pier design. Doing a pad
and pier is significantly more work (i.e.
creating the form) than, say, just a rectangular block that I could simply pour
in the hole with very little
form work.
My question is...Can do that? Can I change the pad/pier to a block, by altering
the dimensions, amount of
rebar, etc. to arrive at an "equivalent"
to the pad/pier??
I welcome any relevant comments/questions/suggestions.
Larry
