Power Pole Clearance - Ground Disturbances

[joro]

Does anyone know of a code or industrial standards that specify the clearance of any ground disturbances should be kept from the base of the adjacent power poles structures to avoid weakening the foundations?

The planned project is for a new rail road track to be constructed parallel to an existing 230 kV T-Line.

Any guidance would be greatly appreciated.

I think that is what geo-technical and civil engineers are for.

Seriously, I don't think a code could cover all of the possible types of soil disturbances, vibration, subsidence, undermining, settlement and the many other concerns that might arise. You need to make sure the utility engineers are involved in review of the construction plans and specs.

Probably should make sure the gandy dancers look up once in a while as well to make sure their crane doesn't get into the 230 kV. That tends be a real drag for everyone concerned.

The utility engineers are involved and seem to be looking to us to provide insight/guidance. The code is pretty clear on horizontal and vertical clearances such as distances from the track to the base of the structures, etc.

Just seem like there would be at the very least recommend practice for building adjacent to existing power lines. Such as guidance that stipulate an accepted protocol for excavating next to existing structures.

Perhaps just wishful thinking on my part.

Codes tend to deal with the end result of construction, not necessarily the construction techniques and methods used.

I'm sure they will know where to find you if their pole falls over.

I am well aware that codes do not stipulate the construction techniques or method used, however code do specify such things as safe working distances from energized parts, clearances, etc.

I don’t believe it is so unrealistic to think with all the power line in the US that some entity might have developed some construction recommendation or best practice guidelines for work being done in close proximity to existing power lines.

consult with the power utility company, at the end, they are the ones who own that power pole/tower or whatever. They are the ones who will determine if you can or can't build something close to their "property". For example, a transformer, owned by the util. company, must have certain clearances and nothing should interfere. I don't think, in my opinion, there will be some damage to the power/tower, since the supporting foundation, prior to being built, it must be designed to withstand earthquakes and the structure itself shall be strong enough to hold for very strong winds.

that shoud be directed to the local power company. dont they own the pole?
