Underground Services Tracing

Mapping of drainage and underground utilities

If you need underground services tracing and mapping for your project, we can help. Below is a list of the utilities you can have surveyed:

Underground pipes, cables, ducts and drainage
Gas, Water, Electric, Heating Systems
Fibre Optics
Foul Water Sewers
Surface Water Drainage

All services are located and mapped

You can have your survey carried out using the latest detection equipment and public records. We locate the underground services on a site and add them to a topographical survey or a measured building survey.

Electronic Detection

Our electronic detection equipment can locate metal cables and pipes by tracing the signals they give off, or by listening for a signal we’ve induced into the service run. This signal can measure the depth of the service run with a margin of 10% error. We can usually detect electric cables/ telecoms cables/ metal, gas and water pipes by using this equipment. Any object with a metal content can be traced if a signal can be induced into it.

Ground Penetrating Radar (GPR)

Ground Penetrating Radar equipment sends radar waves into the ground to analyse patterns in the return signal. We are then able to locate inert objects such as plastic or concrete pipes that cannot be found by detecting an electronic signal. GPR can also verify the depth and position of services located using other methods.

Drainage Surveys

Service tracing teams use electronic sondes and GPR to trace the route of foul and surface water systems across a site. Pipe sizes, incoming systems and invert levels are all recorded during the survey.

CCTV Surveys

2D or 3D deliverable

You can have your underground services survey delivered in any of the following formats:

As a 2D or 3D CAD overlay as part of a topographical survey.
A measured building survey
A 3D Revit Model as part of a BIM deliverable.

Statutory Utilities Search

The presence of any major services on a site and their approximate position can be confirmed by carrying out a desktop utilities search. We always recommend this is done before we start tracing on site.
