Utility Tracing

Scadin provide for tailored-made utility mapping and locating servies. Using a variety of methods to locate and mark underground services up on digital drawings such as RFL and GPR.

A GPR survey measures variation in sub-surface conditions and so can detect many types of pipe and cable as well as other potential hazards or obstructions, providing their physical properties are sufficiently different from the surrounding ground. The data requires complex processing and can often be difficult to interpret, particularly if there are a number of utilities or if the ground has been severely disturbed. Scadin use experienced and qualified geophysicists to undertake GPR surveys and the data is processed using the most up-to-date software available. Information gained from an RFL survey allows a more accurate interpretation of the GPR data and so a more complete picture of the subsurface can be obtained.

A standard component of a full utility tracing survey is the investigation and recording of all inspection chambers and manholes within the site, allowing for a full detailed schedule to be produced for the client.

The location and features identified in the survey are tied in using a total station to provide the best possible positional accuracy and then overlain onto a topographical plan providing clients with accurate utility plans of the site. Although a non-intrusive survey cannot guarantee that all sub-surface features are identified it does allow clients to plan a project with confidence.
