I would contact the utility company.  In my area, there is a list of contractors that work with the city and the utility company ... making the costs and the timeframes for completion a little more certain and much less of a crapshoot. 

Good luck! 

I'm sure the utility company will be able to give you direction on it....and then your building dept. will require you to pull permits for whatevery you're doing.... the electrical inspector in your town/city will need to inspect ... probably after the disconnect and then again the reconnection.... 

Keven, aren't you a power company manager? 😉 I seem to recall having heard that. So you probably know the process for your area? Forgive me if I'm wrong. There are some real gossips around here. LMAO

For my area, it would begin with an email to our local power company's engineering department, to get somebody out there to evaluate it. The property owner would then need to pay a deposit which would be non-refundable and apply toward the final costs, should they decide to go through with the project.

Never experience this but I would start with the utility company. 

I have not Kevin but I'm interested in seeing others answers. Thanks for asking the question.

All real estate is local.

In my slice of Fl paradise, when all players have given their blessing, cost will be $250 per linear foot and yep, you buy the new enclosure also. The shutoff is usually complimentary for existing houses but new construction may be hit with initiation fee. Duke Energy likes $350.  I incurred the additional cost of removing the existing pole that delivered the service initially.

All of this should be familiar to the contractor doing the work and the contractor should need no guidance. DO NOT create a situation where the contractor assumes others will be doing something that should be their responsibility only.

Here in Florida, is it essential to determine if the contractor will subbing any of the work. If so, require subs to sign release before coming on property. You could end up paying for the work twice.

Contact your utility company, it may cost you a lot, if it is even possible.  More often builders adjust their plans and move the structure.

Now is this new construction, or a repair on an existing structure?  your question hints toward both.

On existing buildings where a power line or gas line just needs to be pulled back temporarily this is a common thing and often does not even involve a significant charge.

You need to contact the local utility company and get their input have them handle.

I have not Keven. 

 Public Utility? They are in charge and have the easments - call and ask about their written permission and their permit costs. Assuming you can trench this under a concrete foundation is not for a DIY you must hire a general contractor who has experience with all the entities. Can't tell you costing without knowing:

how deep

how long

how many other properties you will disturb

time it takes to jack the foundation up and pour new one

General idea- 30 feet more than 24 inches deep- if your climate snows you may be required to go 36 inches deep I don't know your codes. A guess for a new power line unobstructed dig $20000. Plus jacking house up and finding more surprises maybe the house cracks in half? I'm going with $60000 for 2000 square foot single story house in dirt that is not granite without winding around gas lines and cable and some bomb shelter for a guess

The power company will give you advice.

Yes, just did it. Power company has to be notified. Miss utility marks underground lines here, and electrician should be involved. Most builders and contractors are familiar with the process.

Red-tape, big bucks and time....Settle in and down on this one. You'll learn

I faint at the thought .... no suggestions.

Sorry, no experience. And I'm sure costs vary greatly by location.

Sorry no clue.

In our area for power lines call Miss Utility , foundation problems consult an Engineer

No, not me. But in Los Angeles it would be super expensive and time consuming.

 I have not had this kind of problem. I am thinking the cure will be expensive.

Contact the local City or County Building Department for more information Keven. They have what you will need or can point you in the right direction in order for you to make an informed decision. 

      Primary power line running through a neighborhood, or just the secondary drop to that particular house?   Relocating a primary line will be a very expensive and time-consuming bureaucratic hurdle (if even allowed).  Relocating the secondary will be more feasible. 

     Talk with a local electric contractor, and with the utility provider.

I had one in NC that had to be moved for a pool and the utility company took care of it because it was running (oblique) across the property and they agreed it would prevent future building on the lot. They didn't charge the owners but, I don't know what your utility company or city permitting requires. 

Call the utility company.  Good luck.

Contact the utility company and see if they would consider relocating the line. If so, what would be the charge?

Keven,

You have quite a bit of advice here.  A

Consult with your broker.

I haven't Keven.

No experience but keep us updated on the progress, costs and outcome please

I did last year and we had to pay for them to move it. 

I have no experience but would contact the utility company for starters. Who is going to pay for this, if it's allowed?

Contact the utility company, city for permits.

No idea.

Cost will vary greatly and often local permits will be expensive too... you need to contact a local electrical contractor for estimates Keven Hoopiiaina 

I have no experience with this.

My advice is to get a professional to tell you what needs to be done

Call the utility company for advice.

Interesting question.  I've not had this situation before.  The only foundation repair I've had to do was on a house with above ground utilities.  I'd suggest reaching out to your power provider.  I do recommend renting a bobcat type tool to do the trenching.  Much quicker, easier and (usually) cheaper than having people dig by hand.
