Utilities Mapping

Terravision uses sophisticated remote sensing instruments from the world’s leading manufacturers. This geophysical survey equipment is used to target buried utilities and infrastructure and form accurate mapping of pipe and cable positions, depths and routes.

The results from our investigations provide a wealth of invaluable information for use prior to excavation, which can be especially advantageous when used as part of a feasibility study, or when incorporated within the design and planning stage of a project.

Having accurate utility and topographical survey information can enable a project design team to anticipate or avoid conflict with existing utilities, and in doing so produce substantial cost savings by eliminating possible utility relocations, design changes or construction delays.

The results of our investigations are delivered as fully structured CAD files along with scaled hard copy plots and associated survey reporting. This information can be combined with existing site surveys or with a topographical survey coordinated by our survey team.

Services are detected using a combination of electro-magnetic transmitters and locators, flux gate magnetometer, pulse induction metal detector and ground penetrating radar (GPR). This information is coordinated using robotic total station and RTK GPS / GNSS for office-based processing and drawing production.

Rather than carry out one size fits all ‘blanket surveys’, we advocate an investigative and interpretive methodology where all aspects of the project area and survey data are considered and incorporated into our procedure. This connected approach aims to avoid the simple, and often incorrect, delineation of signals and reflections that some predetermined and solely grid-based survey specifications may yield.

We are always happy to suggest survey specification tailored to site specifics and project requirement. We take the best from existing survey guidelines, such as PAS 128, and combine this with our proven techniques and adaptive methodologies to achieve accurate, comprehensive and reliable mapping of subsurface apparatus.
