I'm trying to work out how deep the sewer pipe adjacent to my plot is. Can anyone provide some advice as to how best to find this out ? My first thought was going to be to buy the Scottish water plans through National one call. But will they even contain info on how deep the pipes are buried ? ? I'll pop over to the site later and see if I can find open up any manholes. What other options do I have ? Is there a way to scan for the sewers / depths from the ground ?

I've done some rough costing myself. But there are still a lot of unknowns- groundwork, roof etc. Am hoping the QS can give me estimates for Labour and not just materials. Is this something that a QS would do ?

Edinburgh.

Does anyone have any recommendations for a QS / QS service ?

Thanks for the suggestions all.

Can anybody recommend a good architectural technician in the central belt of Scotland or close enough ? My project is in Edinburgh.
