Mike-
The contractors will usually recommend whatever is easiest for them to deal
with.
Did you ask your engineer about the sandy soil?

Subject: [TowerTalk] Crank-up base
I'm negotiating to get the base for my HG70-HD dug and poured. I have a high
water table, soil tends toward sandy, and an engineer said he would be
happier if the hole were 10' deep rather than the 7.5' called for in the
manual.
The concrete guys I'm talking to want to line the hole with plywood to
prevent collapse. One guy who does a lot of big sign installations says he
does it regularly, and there would be no stability issues.
I've read several times the pour needs to be into undisturbed soil, no
backfill, altho that's not in the manual.
What are the facts?
73, Mike NF4L
