mention it. I have no idea how old it is.
Since way back then (70's? 80's?), the TIA-222 has been written and
revised several times. It is the industry standard for tower installations.

Sounds like your engineer wasn't real helpful. If you're going to do
it all yourself, contact a local excavator and ask their advice, especially
for your sandy environment. In this case over-engineering mostly means a
bigger base since you don't have any control of what's above it. There is a
chance that a tower with a base in sand will start to lean away from the
prevalent wind direction over time, being pushed by the wind. A bigger base
will minimize this. A single guy to the top of the bottom section in the
direction of the prevailing wind will help too.
