TSS, I don't think a lineal foot price from anyone would be the way I would price this out.
For what it's worth, probably not much, but my opinion is to price it out this way. Material, plus man and machine time, profit and over head, and subs.
Brake this into man hours per task, cost of material, and sub work. Add in a CYA factor.
The guy with the correct equipment, and the most efficient equipment will win this bid.
