Beneath our feet lies a complex network of vital utilities and infrastructure, including water pipes, gas lines, electrical cables, sewer systems, and more. When planning any construction or excavation project, whether you’re a civil contractor or a homeowner with a DIY project in mind, preventing unintended utility strikes paramount.
How we go about it:
We use advanced Electro Magnetic Technology to induce an electrical frequency into conductive utilities such as electrical, communications (Telstra, NBN and others), gas lines, steel/cast iron water pipes. By inducing an electronic signal into pipes and cables using clips clamps and other methods we can then trace that signal along the service to the next pit, valve or connection point.
Where services are non-metallic, such as storm water drains or communications ducts containing fibre optic, we are able to insert specially designed rod (long flexible fiberglass hose with internal highly conductive copper wires) and trace the rod in the conduit, this includes under roads, drains, concrete and more. In addition, using specialised equipment called a sonde, we are able to locate the point of blockages and obstructions in pipes and conduits allowing you to know where the issue is and where to dig to undertake remains.
We work to gain a complete understanding of all the services within and adjacent to your work area to minimise the risk to you and others and to keep your project on time and on budget.
We have resources available to carry out Service proving via Non-Destructive Digging / Hydro-Vacuum Excavation. This is often a requirement to enable you to carry out your planned excavation and works near other authorities assets. We would typically package this work with suitable backfill (placing risers for the services to be easily identified at a later date). This can save $$$$s when completed during design stage, both in terms of delays, re-design costs and variations.
Non-Destructive Digging / Hydro -Vacuum Excavation: This method typically involves the use of pressurized water and an industrial vacuum system. A high-pressure water jet is used to break up and loosen the soil, while a vacuum system simultaneously sucks up the slurry of water, soil, and debris. This process allows for precise excavation with minimal disruption to underground structures.
Reduced Risk: Non-destructive digging significantly reduces the risk of damaging utilities such as gas lines, water pipes, fiber optic cables, and electrical conduits, which can be costly and potentially dangerous if disturbed during excavation.
Environmental Benefits: The technique is environmentally friendly because it minimizes soil disturbance and prevents the release of contaminants into the surrounding area. It also reduces the need for hauling away excess soil.
Cost-Efficiency: While non-destructive digging may have higher initial equipment costs compared to traditional digging methods, it often proves to be cost-effective in the long run because it reduces the expenses associated with utility repairs, safety incidents, and environmental cleanup.
Accuracy: This method allows for precise excavation and location of underground utilities, making it easier for workers to access and repair them without causing additional damage.
Non-destructive digging is commonly used in urban areas, construction sites, and any situation where there is a need to dig or excavate near existing underground infrastructure. It is a safer and more efficient alternative to traditional hand-dug excavation methods that allow the risk of accidentally damaging utilities.
We can offer a complete package service, carrying out a survey pickup of the results of our service locating or proving, and then plotting these on a site plan or similar. This is often of value when projects are continuous for an extended period or just straight incorporation into your design. We can provide files in CAD format and PDF.
