Cable Locating Sydney
Need a vacuum truck in Sydney for safe, non-destructive digging? Contact Smartscan Locators for fast, certified excavation solutions.
Cable locating in Sydney confirms the exact position of underground electrical and communication services before excavation. Smartscan Locators performs on‑site cable detection that goes beyond BYDA plans by physically tracing and verifying live utilities using electromagnetic locating and ground penetrating radar.
Our team locates power, fibre, data, and communication cables across residential, commercial, and civil sites throughout Greater Sydney. All locating aligns with AS 5488 standards and includes clear surface markings and reporting suitable for excavation, design, or construction planning. This service reduces strike risk, prevents outages, and supports compliant, safe digging across Sydney’s varied ground conditions.
Why Cable Locating Is Required Before Digging in Sydney
Cable locating confirms real‑world utility positions that plans alone cannot guarantee. Sydney’s underground network includes legacy services, undocumented assets, and alignment changes that create strike risk during excavation.
Smartscan Locators performs physical cable detection to support safe digging, permit compliance, and contractor due diligence across NSW.
- Confirms live cable locations beyond the DBYD plan accuracy
- Reduces asset strikes, outages, and repair costs
- Supports council, rail, and Tier 1 compliance requirements
- Provides marked services ready for excavation or vacuum exposure
How Cable Locating Is Performed on Site
Electromagnetic Cable Tracing
Electromagnetic (EM) locating is the primary method for tracing power lines and metallic communication cables underground. This technique uses signal induction or detection along a cable’s conductive path to identify alignment and depth. It is effective across most Sydney residential and commercial properties where metallic assets are present. EM locating works quickly and delivers accurate results when services are continuous and accessible. It’s particularly useful in pre-dig assessments and planning around live assets. This method is often the first step in a layered locating process and supports compliance by identifying known utilities prior to excavation, trenching, or non-destructive digging.
Ground Penetrating Radar Verification
Ground Penetrating Radar (GPR) enhances locating accuracy for non-metallic cables, such as fibre optic lines, PVC conduits, or unknown assets. GPR emits radar pulses into the ground and detects subsurface anomalies that may not carry an electrical signal. It is commonly used in complex environments like the Sydney CBD, heritage zones, and areas with congested utility corridors. GPR is highly effective for resolving conflicting plans, verifying cable positions, and supporting AS 5488 quality classification. This method is often paired with EM locating for comprehensive coverage, particularly where utilities are buried in sandstone, clay, or mixed soil conditions.
Trace Rods
Trace rods are inserted into non-conductive conduits to transmit a detectable signal when EM locating isn’t possible. They enable accurate tracing of private services, PVC conduits, or telecom ducts that lack electrical continuity.
Sondes
Sondes are small transmitters used inside pipes or conduits. When paired with a locator, they allow precise tracking of non-metallic utility paths across residential and civil sites.
Surface Marking
Surface markings are applied using colour-coded paint or flags to identify each detected service. These markings follow AS 5488 conventions and prepare the site for excavation or mapping.
Certified Cable Locating Services Available Across Sydney
Smartscan Locators provides fully compliant cable detection services for residential, commercial, and
infrastructure excavation projects.
Power Cables
Our technicians locate live low and high-voltage power lines using electromagnetic detection before any excavation, trenching, or boring begins, reducing the risk of strikes, power outages, and costly service disruptions.
Telecommunications
We detect Telstra, NBN, fibre optic, and other communication cables, including both metallic and non-metallic lines. This includes EM locating and GPR verification for buried data lines, conduits, and carrier-grade telecom infrastructure.
Private Services
We trace undocumented or privately installed underground cables not covered by BYDA. This includes lines servicing private properties, developments, or legacy infrastructure where plans may be outdated or missing.

Common Questions About Cable Locating Services
Do I need cable locating if I have BYDA plans?
Yes. BYDA plans provide asset records, not physical confirmation. Cable locating verifies actual positions on site and reduces strike risk during excavation.
How accurate is underground cable locating?
Accuracy depends on the method and site conditions. EM locating achieves reliable surface alignment, while GPR improves confidence for non‑metallic or congested services.
When is GPR required for cable locating?
GPR is required where cables are non‑conductive, deeply buried, or located in complex environments such as CBD sites or rail corridors.
How much does cable locating cost in Sydney?
Pricing follows a call‑out plus hourly structure. GPR incurs an additional rate. Residential and commercial costs vary by site size and complexity.
How quickly can a cable locator attend my site?
Smartscan Locators offers same‑day and short‑notice attendance across Sydney, subject to availability and site access.
What happens after cable locating is completed?
Marked services allow safe excavation. Vacuum excavation can be used to expose services, and CAD mapping can support design or construction planning.
