What is the regulation depth of a BT underground cable ?


[link to this post]
 
Today I had some Leylandii trees taken out along my boundary, and along with the tree roots came half the cable. BT say that the damage is down to me, but the lady did say that the cable had to be at the regulated depth, and protected, but she didn't say what the "regulation depth" was ?

I'm not sure how this cable could have been avoided - it was only about 1 foot down, and although it was a lightly armoured cable, there was no other protection. Does anyone know what the regulations say ?

Quick - fill it all back in, plant a few small things and then report a line problem! wink

As far as I'm aware, there are no regulations concerning a mimimum depth for buried services (not that it means there aren't any, just I don't know of any).

In fact, the The Construction (Design and Management) Regulations 2007 put the onus on the 'digger' to check for utilities before carrying out work.

This says:
The Construction (Design & Management) Regulations 2007 (CDM 2007) came into force on 6 April 2007, and place legal duties upon individuals or corporations to ensure that they are acting responsibly with regard to matters of health and safety. Beginning excavation works in areas that may contain unseen services, without having taken measures to minimise the risk of striking apparatus is a breach of the regulations, and can be pursued under law.

More info here.

Off hand it is 350mm for telecom cables, and 250mm for cable tv. but it would depend on how long they have been there as I'm sure that differant regs applied at one time. Have a google for Openreach new build regs. It sounds expensive and you may now have a reason to really hate BT

You're not having much luck with Broadband are you?

Sigh.

On the plus side maybe it will finally result in your line being properly fixed - I just hope it doesn't cost you too much frown

BT Openreach say that they will pass the costs on to the contractor doing the work, and not me. However, I don't think they will have a leg to stand on, with the cable being less than 1 foot down, with no duct or other means of protecting the cable.

The current Openreach Builders Guide page 13 specifies 600mm min to 700mm max below finished road level on new estates. Other dimensions and specifications are also tabulated. http://www.openreach.co.uk/orpg/networkinfo/developn...

That is the road level, the depth for across gardens looks like it may be 350 to 450mm on page 12, where the external NTE for new properties is described.

What it was when the property was built and wiring laid is anyones guess.

Time to talk to insurance people maybe, but the onous is often on the person doing the digging to check, or at least enquire with property owner. The blame game is pretty much the case now, but if Openreach or BT had used even just slightly armoured cable, you could argue that they have done a reasonable level of protection. Would the current 50mm PVC pipe offer more protection?

Do check that your contract with the contractor who removed the trees did not say that you have checked for underground services, and did you check with BT to see if there are/were any underground cables? I assume that this work was carried out on your land?

The PVC conduit does nt really offer much protection, its used, and left with a draw line so that cables can be run after the ground work has finished if necessary.
