There is a lot of discussion here on having drawings reviewed by a PE
prior to getting the permit. In the grand scheme of things, if the goal
is to make sure your expensive tower installation stays up, it would
make probably more sense to have a PE look at the whole works, before
pouring concrete, and AFTER IT'S UP, to verify that things like guy
anchor integrity, base-tube drainage, guy/guy-hardware materials used,
ALL the nuts/bolts are in place and properly tightened, guys tensioned.
If I was a city-planning burocrat, charged with protecting the
unsuspecting public from unsafe hamradio towers, I'd insist you have a
PE do *that*. When's the last time you ever saw a building inspector
actually climb a tower, or pull out his LOOS gage, or could tell the
high-strength guy cable from the cheap stuff? Or how well screwed the
screw-in guy anchors were (I'd want that *witnessed*)...
