WHAT IT IS

What is Underground Cable Locating?

Cable locating is the process of detecting and tracing evidence of underground cable routes so project teams can plan work around them before ground disturbance begins.

For conductive cables, metallic sheaths or tracer wires, electromagnetic (EM) locating can be used to apply or detect a signal and trace the route. Ground Penetrating Radar (GPR), plans, pits, cabinets, access points and other site evidence may be used as supporting information when the target is non-conductive, difficult to trace or installed in conduit.

The result is an evidence-based indication of the likely cable route, not an absolute guarantee that every cable is detectable. Where exact position or depth is critical, physical verification should be considered.

Key distinction: locating provides field evidence. Exact position or depth for critical excavation may require physical verification.

WHEN YOU NEED IT

Locate Cables Before Work Begins

Cable locating is commonly used before work that could contact or disturb buried infrastructure.

CABLE TYPES

Types of Underground Cables we Investigate

The appropriate method depends on the cable construction, access, tracer features, site conditions and available records.

How Cable Locating Works

The right method depends on what the pipe is made of. Most sites need both.

METHOD SELECTION

EM Locating, GPR and Physical Verification Serve Different Purposes

Method

Best used for

Key limitation

Electromagnetic locating (EM)

Conductive cables, metallic sheaths or tracer wires that can carry or respond to a signal.

Signal quality can be affected by interference, bonding, parallel conductors, depth and access.

Ground Penetrating Radar (GPR)

Supporting investigation for conduits, trenches, disturbed ground and some non-conductive targets.

GPR interpretation depends on ground conditions, depth, target size, surface access and contrast.

Physical verification / NDD

When exact cable position or depth must be confirmed before high-risk or close-proximity works.

Requires access and excavation/verification planning; locating is normally used first to guide verification.

ACCURACY & LIMITATIONS

Cable Locating is Evidence-Based, Not an Absolute Guarantee

EM locating traces an electromagnetic field associated with a conductive cable, sheath or tracer rather than physically seeing the cable itself. Interference, poor connections, parallel services, damaged conductors, depth, shielding and site conditions can affect the response.

Non-conductive or undocumented cables may not produce a traceable EM response. GPR can provide useful supporting evidence in suitable conditions, but it also has limitations and does not guarantee identification of every target.

If excavation will occur close to a critical cable, or if an exact position or depth is required, physical verification such as non-destructive digging should be considered before work proceeds.

Important: Do not rely on markings or plans alone for high-risk close-proximity excavation. Confirm the required level of certainty for the work and use physical verification where appropriate.

WHEN MORE CERTAINTY IS REQUIRED:
Use the locating result to guide survey mapping or physical verification such as non-destructive digging before close-proximity work around critical services.

PLANS VS FIELD LOCATING

BYDA Plans and On-site Cable Locating are NOT the same thing

Before You Dig Australia (BYDA) plans are an important planning input because they can show information supplied by participating asset owners. They do not replace an on-site investigation.

Plans can be schematic, incomplete, outdated or unable to show private and undocumented services. On-site cable locating uses field evidence to investigate what can actually be detected at the project location.

For complex or high-risk work, the strongest pathway may combine plans, on-site locating, survey mapping and physical verification.

Use the Right Level of Certainty

Planning: BYDA and available site records.

Field evidence: EM, GPR, pits, cabinets and visible infrastructure.

Mapping: survey located information where required.

Verification: physically expose the target when exact position/depth is critical.

FAQ

Common Cable Locating Questions

What is cable locating?

Cable locating is the field investigation used to detect and trace evidence of underground cable routes before excavation, drilling, construction or other ground-disturbing work.

What types of underground cables can be located?

Depending on detectability and access, cable locating may investigate electrical power, communications, copper, NBN, private electrical, lighting, signal, control and some fibre-route infrastructure.

Can fibre-optic cables be located?

The fibre itself is non-conductive, so it may require a conductive tracer wire, metallic element, traceable rodder, associated conduit or supporting GPR/site evidence. Some fibre routes cannot be confidently identified without physical verification.

Can GPR locate underground cables?

GPR can support cable and conduit investigations in suitable ground conditions, particularly where the target is non-conductive or EM tracing is inconclusive. It should be treated as supporting evidence rather than a guarantee that every cable will be detected.

How accurate is cable locating?

Accuracy depends on the cable, signal quality, access, depth, interference, nearby services and site conditions. Where exact position or depth is critical, physical verification should be used.

Do I still need cable locating if I have BYDA plans?

Yes when the project requires field verification. BYDA plans are an important planning source, but they may not show private, undocumented or accurately positioned services. On-site locating investigates field evidence at the actual work area.

What should I provide before the job?

Provide the site address or suburb, proposed work area, type of excavation or construction activity, available plans, access details and the date or deliverable you need.

How accurate is the marking on site?

We mark position on the surface with colour-coded spray paint, chalk, crayon, masking tape or permanent marker depending on the surface type, and record the same information in your report. For permanent or semi-permanent markings, tell us at booking.

How quickly can you get on site?

Same-day and next-day bookings are available across Sydney metro. We recommend 3–5 days’ notice prior to excavation where possible.
