Cablefind is a locally based company, offering professional commercial pipe and cable locating services throughout the Northern Rivers area. Many commercial excavation projects require the expertise of a registered and approved locator in order to avoid damaging infrastructure assets during excavation. These assets can be extremely costly to repair or replace, or can cause serious injury or even death, if struck.
Our commercial locating services are an invaluable investment. We’ll not only save you time and money, but also give you complete assurance of job safety. We’ve listed our extensive services below. If you would like to book a commercial cable or pipe locating job, head over to our easy online booking form and we’ll be in touch as soon as possible.
More and more communication lines are being put underground. Now, with the new NBN network fibre-optic running in all directions, there’s more more congestion than ever. Additionally, there are Telstra and Optus services, as well as NextGen and other carriers with various fibre-optics criss-crossing underground.
Power cables are the most serious cables that need to be avoided. They can carry various voltages ranging from 33,000 volts down to 240 volts, with all having the ability to cause serious injury and/or death. Excavating even close to these cables can have disastrous consequences.
Gas lines are one of the more obscure services that run through properties and one of the hardest services to locate. Gas is notorious for being struck and can often lead to explosions or fires. Gas is classed as one of the more serious services to avoid.
Fibre optic is a relatively new service which is now being rolled out everywhere. It can even be found in rural settings, where farmers may think it’s highly unlikely to be under their property. A fibre optic cable has glass multi-stranded fibres, with each fibre being very small in diameter. Any damage is therefore extremely hard to repair. It’s very difficult to detect underground because it doesn’t have any conductive elements to it and, for these reasons, is the most costly service to repair
Ground Penetrating Radar (commonly called GPR) is the general term applied to techniques which employ electromagnetic waves to map structures, pipes and cables and other features buried in soil, concrete, road paving or other surfaces.
GPR is a non-invasive imaging technique that was developed in the 1970s and is used for shallow, high-resolution, subsurface investigations of the earth. It’s commonly used for services locating and investigations of an environmental, engineering, archaeological or forensic nature, as well as other shallow investigations. It is quick, easy to use and inexpensive in comparison to other investigation methods.
GPR can penetrate to about two metres, if soil is dry and/or sandy. Soils with a high dielectric level (water retention) will slow the radar wave and it won’t be able to penetrate as far. Water saturation dramatically raises the dielectric of a material, so a survey area should be carefully inspected for signs of water penetration before beginning any GPR work. Clay soils are often unworkable with radar.
GP Radar is used to find the following services:
Services mapping is a service that allows the end user to visually see where all services run in a map overview. The map is not intended to be of a survey standard but a general overview of where all services lie on the property.
With services mapping, the first step is to locate all the services that are under the ground. Once the services have been located, then each service can be pointed and added to the GPS coordinates. If higher levels of accuracy are needed then the next step would be to pothole each service to verify its location. Once the service is verified, the points would be taken and the depth would be noted as well. The results would be saved as a KML file which is able to be viewed via an online viewer.
This service is ideal for sites where future development may be planned. The data provides a historical record together with a clearer picture of where the existing services on the site run.
Cablefind offers a trailer-based mini back unit that allows greater access to most restricted areas, unlike the large vacuum excavator trucks. With a smaller capacity of 500 kg, it’s ideal for a small number of potholes.
This service is typically used to verify services that have been located using either GP Radar or EM Locating. It’s also very handy to find buried pits or valves that are below the surface and is also great for cleaning pits and drains.
The mini vac service can also be used for small excavation jobs where trenches need to be dug across congested areas. As with hydro excavation, this method is totally non-destructive to any pipes or cables, making it an ideal way of exposing the services
Cablefind will oversee the process from start to finish, including obtaining all plans from the various asset owners and builders, locating all services, and the verification process of potholing. Potholing is an important step of safe excavation, which enables the user to determine the precise location of all services on the building site. This project management service is offered as a total package and is designed to take the pressure off a Construction Manager.
Included in this service is the directing of other subcontractors to facilitate the work that needs to be carried out on site to survey all assets.
The safety of those working around infrastructure assets and the community, and the infrastructure assets themselves, is of the highest priority when undertaking any commercial excavation project. For these reasons, there are important steps that must be taken before beginning any project.
Dial Before You Dig is a FREE national referral service. It is designed to assist in preventing disruption and/or damage to Australia’s vast infrastructure networks which provide the essential services which are used on a daily basis.
Most of Australia’s major infrastructure asset owners are Members of Dial Before You Dig (DBYD). The DBYD service offers a single point of contact to request information about the infrastructure networks at the planned project site, without the need to contact utility organisations individually.
