Every dig carries risk. Hit a power line, sever a water main, or damage telecommunications infrastructure and your project stops. The costs multiply: emergency repairs, project delays, contractor coordination, regulatory reporting and potential safety incidents.
Gold Medal Services uses Ground Penetrating Radar (GPR) and electromagnetic location technology to scan up to 8 metres below the surface. You get a 3D map of what’s underground before any excavation starts.
Our equipment identifies underground services that standard methods miss:
The GPR system works where other methods fail. No need for direct access to services or metal-only detection. You get complete subsurface visibility.
Site Assessment: We review your project area, existing plans and access requirements.
Field Scanning: Our CertLoc-certified operators scan the designated area using GPR and electromagnetic equipment. The system records positioning with 1-5cm accuracy using GPS, GLONASS, Galileo, and BeiDou satellites.
3D Mapping and Reporting: You receive annotated maps with precise utility locations, depths, and geolocation data. We deliver files in CAD or GIS format for integration with your project documentation.
Our GPR system delivers results that meet project compliance requirements:
Augmented reality overlay lets us superimpose scan data directly onto the site in real time. You see exactly where utilities run before any ground disturbance.
GPR proves essential for projects where subsurface unknowns create risk:
We’ve mapped sites across Defence facilities, commercial developments, municipal infrastructure, and industrial complexes throughout the NT.
Our team holds CertLoc (formerly Dial Before You Dig) certification. Every scan meets NT regulatory requirements and industry standards.
GPR mapping integrates with our NDD hydroexcavation, CCTV inspection and hydraulic design services. One point of contact coordinates all subsurface work.
22+ years working on Defence facilities and over 30 years serving NT government clients. We understand security protocols, compliance documentation and operational requirements.
Survey-grade positioning and professional reporting that engineering teams, certifiers, and contractors can use immediately. No ambiguous markings or rough approximations.
Prevent utility strikes, avoid project delays, reduce insurance claims, and maintain site safety. One GPR scan typically costs less than one day of project downtime.
