UNDERGROUND UTILITY SURVEYS
Underground Utility location is fast becoming a developer's necessity with on going Health & Safety legislations.
For many years, SDS has undertaken service location surveys for a variety of clients, from local builders to Water Authorities and large scale Developers.
Continuing to update our Radiodetection Units has allowed us to stay ahead of competition and ensure that clients keep coming back to receive the highest standard in service location with a Ferrous content.
Radiodetections RD4000 T10 does not only serve well for the location of Sewers, the same Units are used to induce signals onto underground services through a variety of methods, such as:
1) Induction through positioning of Generator Unit, over service
2) Direct contact via hard wire Leads which attach to the Metallic Structure / Service
3) Induction via Coroner Rings, of which we utilise all sizes available, i.e. 100mm Dia - 300mm Dia
These are especially useful and accurate when defining Electricity Cables and multi directional cables for services such as BT where access to chambers are generally plentiful.
The Survey Results can be temporarily marked on the ground for immediate use on site. However, it has become common practice to survey in the results with a Total Station for fast production of accurate drawings.
This information may be added to an existing Topographical Survey or overlaid onto Ordnance Survey Background with the latest in GPS Equipment.
