Inserting ducts into an Easement - how to terminate pending use?

[Ferdinand]

I have an easement through a neighbour's plot which I am planning to open up in order to insert pipes and ducts for future services. It is 2m+ wide with a wording allowing the insertion of new service media incl. eg for the supply and removal of energy, telecomms, data, water, sewerage etc and "all structures, machinery and equipment ancillary to those media".

 

I am planning to insert a soil pipe run, a water pipe run, and 3 or 4 runs of normal 2" duct.

 

I can terminate the runs in my plot alright, but will need a "something" at the other end just short of the pavement in my neighbour's plot such as a chamber or similar. At the moment the neighbour is just a plot with nothing built on it, hence the desire to put things in now before it would cause significant disturbance.

1 - Can anyone tell me how I should do the terminations at the other end, to keep them protected and tidy until they are used in the future?

2 - It is quite a wide easement at 2m+ and I want to put an indicator bollard or similar just to remind them where the far edge is to stop them digging it up. Can anybody suggest a suitable item to concrete in for this purpose?

3 - Are there regulations as to depths and so on for trenches and hazard tape etc. Can anyone point me to a list?

Cheers

You can get a wide range of duct access boxes/inspection chambers..

If the soil isn't very free draining I would extend the duct into the chamber and perhaps seal the end with expanding foam leaving the draw rope coiled up in the chamber. 

 

As for depths of electric cables see bottom of page 11 and page 12 for the tape...

That suggests 450mm is deep enough but I though most were laid at 600mm.

Google can find fancy cable/duct marker posts but perhaps cheaper to use a concrete fence post or similar?

Water has to be 750mm deep where I am, not sure if this applies to all areas but I would expect so as obviously this is a freezing issue.
