    Builders, contractors, farmers, excavation companies, councils, landscapers, underground network maintenance workers, plumbers, home owners, cable and pipe location companies – in fact anyone who intends to work around any infrastructure asset(s) should lodge a FREE enquiry before commencing.

  • 5. How much does it cost to obtain a location plan?

    Lodging a Dial Before You Dig enquiry is FREE.

    However in some instances, infrastructure asset owners may charge for the supply of infrastructure information – although this is normally only for large development related enquiries or planning/design enquiries where no excavation is taking place.

  • 6. What type of information is provided?

    Asset owners provide information about the presence, approximate location (usual in the form of plans) and instructions about working around their registered infrastructure asset.

    They DO NOT pinpoint the exact location of the infrastructure asset. Therefore, Duty of Care must be exercised when working around any infrastructure assets.

  • 7. Are cable and pipe networks installed in a straight line?

    No. Mainly due to obstacles that may have been in the vicinity when the cables or pipes were installed.

    And NEVER assume the depth or alignment of pipes and cables.

    Due to the possible deviation in alignment, manual excavation (if instructed by the asset owner) may be required to determine the exact location of infrastructure assets to avoid any mishaps.

  • 8. Do utilities charge for on-site engineering assistance?

    Utilities may provide free on-site or over the phone engineering advice when necessary.

    However, a fee may be charged when the relevant utility is requested to locate specific infrastructure assets or provide on-site advice.

    Clarification of fees can be obtained by directly contacting the relevant asset owner.

  • 9. Will I be financially liable for damages to infrastructure networks?

    Yes, court proceedings may commence against individuals and / or companies for the recovery of cost of repairing or reinstating damaged assets where negligence appears to be a contributor.

  • 10. If I lodge a Dial Before You Dig enquiry and advise of my plans to excavate, am I still responsible for any damage that I may cause?

    Yes, all individuals have a Duty Of Care they must observe when working in the vicinity of infrastructure networks and it starts with lodging a FREE enquiry with Dial Before You Dig.
