I always exclude any utility work from my bid. Unless they have provided you with detailed plans of what needs to be done there is no way you can provide an accurate price. I'm also CA and have the pleasure of dealing with one of these large easy to work with utilities (I think Nick knows what I'm taking about). We often don't have any thing from the utility engineers until we are 80% complete with the project. Until we have this information we can't provide the cost. Even a single family dwelling with a 200 amp service will take 3-6 months for the utility to engineer the 3" conduit that needs to run from the new panel to the existing pull box at the curb.
