Underground Service Tracing & Utility Survey
Service Tracing Surveys

Underground utility location and mapping services available throughout the UK to PAS128 standards.

Using the latest in underground pipe location and cable detection devices Ogilvie Geomatics Utility Mapping Solutions offers you a complete underground utility location and mapping service.

We have invested in the very latest dual frequency ground penetrating radar (GPR), radio detection and GPS equipment. This enables the mapping of all types of underground utilities before you dig with minimal risk.

We undertake underground utility mapping to provide projects with up to date, accurate information relating to underground services. These typically include communications (BT/Virgin media etc), Water, Gas and electricity . The depth of investigation will depend on the site, but will usually be between 2-3m. Utility mapping is efficient when a combination of techiques is used.

Underground Tracing Surveys

Radiodection cable and metal pipe locators

This has become the accepted method/technology for finding buried metal cables and pipes. By using a generator to induce a signal along a utility, the signal can be traced to provide reasonably precise locations.

Ground Radar (GPR)

Ground penetrating radar is a nondestructive geophysical method that produces a continuous cross-sectional profile or record of subsurface features, without drilling, probing, or digging. Ground penetrating radar (GPR) profiles are used for evaluating the location and depth of buried objects and to investigate the presence and continuity of natural subsurface conditions and features.

Ground penetrating radar operates by transmitting pulses of ultra high frequency radio waves (microwave electromagnetic energy) down into the ground through a transducer (also called an antenna). The transmitted energy is reflected from various buried objects or distinct contacts between different earth materials. The antenna then receives the reflected waves and stores them in the digital control unit.

Used in conjunction with a radio detection device, it can provide useful information to determine non metallic services.  We now have a portfolio of IDS dual frequency GPR systems - the latest in GPR technology.

  • Metallic & Non-Metallic Pipes

PAS 128

As the demand on the nation’s infrastructure continues to grow due to new developments, the need to replace and/or maintain existing utilities increases. It is therefore essential that accurate information about where underground utilities are actually located is available.

PAS 128 aims to provide a clear and unambiguous provision for those engaged in the detection, verification and location of active, abandoned, redundant or unknown utilities.  Ogilvie Geomatics complies with PAS 128 guidelines.

Cost:

Save on conventional excavation methods. More accurate utility surveys mean you experience fewer design changes, fewer delays and penalties.

Ogilvie Geomatics Utility Mapping Solutions offer an innovative combination of advanced detection and mapping technologies including Radio Frequencies, Ground Penetrating Radar (GPR) and Global Positioning systems (GPS). We deliver the safest and most cost-efficient utility surveying, mapping solutions available to the utility professional.
