What this service does
Cable detection combines passive and active locating approaches with GPR where necessary to trace buried electrical and telecom infrastructure and reduce strike risk before intrusive works.
Common applications
- HV/LV cable route tracing
- Telecom and fibre corridor support
- Depth estimation
- Excavation clearance
- Route verification
Methodology
We start by reviewing drawings, target depth, planned intrusive works and access constraints. Field collection is then completed using a survey pattern appropriate to the site, with complementary locating methods used where they improve confidence. Findings are interpreted, positioned and issued in clear engineering deliverables.
Limitations and quality control
Signal tracing depends on access, conductivity and network configuration. GPR is used to support the investigation where direct tracing is limited or non-metallic ducting is present.
Typical deliverables
- Marked-up plans and/or CAD drawings
- Depth annotations where technically supportable
- Survey coverage and methodology record
- Engineering report with findings and limitations
- GIS-compatible outputs when required
