Our Core Services

Underground Utility Locating

We utilize high-accuracy methods for locating utilities, such as:

- Electromagnetic Locating (EML)

- Ground Penetrating Radar (GPR)

- Private service identification

- Subsurface anomaly detection

We detect both metallic and non-metallic utilities, encompassing electrical, communications, water, gas, sewer, stormwater, and unknown assets.

Ground Penetrating Radar (GPR)

Crucial for identifying:

- PVC and non-conductive pipes

- Stormwater and drainage

- Voids, anomalies, & undocumented assets

GPR provides essential subsurface intelligence when traditional electromagnetic locating isn't sufficient.

Non-Destructive Digging (NDD) / Vacuum Excavation

For QL-A verification, we safely use non-destructive digging methods to expose underground services and confirm:

- Depth

- Alignment

- Material

- Condition

This practice eliminates strike risk and guarantees the highest level of assurance under AS5488.

Utility Surveys & Mapping

We offer survey-grade utility mapping tailored for design and construction workflows, including:

- Total station & RTK GPS pickup

- CAD drawings

- GIS datasets

- PDF utility plans

- 3D spatial models

- AS5488-classified SUI reports

Our integrated detection and survey workflow provides design-ready outputs that minimize clashes, delays, and uncertainty.

Industries We Support

We serve various sectors, including:

- Civil construction & infrastructure

- Commercial & industrial developments

- Road, rail & utilities projects

- Surveying & engineering firms

- Telecommunications & electrical contractors

- Councils & government authorities

If your project involves excavation, design, or asset verification, we are here to support you.

Our Process

- Pre-Site Assessment: Review BYDA responses, plans, and project scope.

- Field Locating & GPR Scanning: Multi-sensor detection for thorough coverage.

- NDD Verification (QL-A): Safe exposure of vital assets.

- Survey Pickup: Precise spatial positioning to MGA/AHD datums.

- AS5488-Compliant Reporting: Clear, structured deliverables for engineers and project managers.

Every step is crafted to minimize risk and maximize certainty.
