If site work is new to you... don't bid it.
You need to learn the ins and outs at someone else's expense.
You'll have to sub out:
The augering
The rebar cage
The survey
Rent a trencher/ sub a backhoe
Rent a crane/ sub out the pole erection
Rent/ buy a concrete vibrator, pole specific troweling tools, very large wrenches, ... on and on it goes.
and...
Order a batch truck with the right mix
...and pass unforgiving site inspections.
I had a longer post.
It started to reach Moby Dick/ War and Peace proportions.
Even it wouldn't be enough to help.
This is the kind of project where experience is everything.
The process is drastically more involved that it first seems.
It's such a hassle that most (commercial construction) contracts break the site work out into a separate bid.
I've seen a single site contract -- just one parking lot -- break a contractor financially. As you might expect, he didn't see it coming -- though everyone else did. (His crew was too slow, and getting behinder with every passing hour.)
