       maintenance of competency standards. However, performance and the advice given will always depend on the
       nature of the individual engagement.
      Neither the Telstra Accredited Plant Locator nor any of its employees are an employee or agent for Telstra.
       Telstra is not liable for any damage or loss caused by the Telstra Accredited Plant Locator or its employees.


      Electronically derived subsurface measurements (e.g. depths/alignments by locating devices)
       All locator provided measurements for Telstra assets must have the AS5488-2013 quality level specified
       - (e.g. QL-A, B, C or D). These quality levels define the accuracy of subsurface information and are
       critical for determining how the information is later used – for example if suitable for excavation
       purposes.

           1) An example of a subsurface measurement with no quality level specified – (i.e. not to be used)
                                                Telstra cover - 0.9m
               The measurement above has no AS5488-2013 quality level specified and must not be provided by a locator or
               used for design or construction. This is because it is not known whether the measurement is actual or derived
               (where ‘actual’ means validated and ‘derived’ means assumed and not validated, e.g. electronic or other). Typically
               damages occur by constructors incorrectly using unvalidated measurements as actual measurements.




           2) An example of a subsurface measurement with quality level B specified –
                                                 Telstra cover - 0.9m (QL-B)
               Where (QL-B) complies with AS5488-2013 QL-B (for example an electronic location that complies with QL-B)
               (Note QL-B means it has not been validated and must not be used for construction purposes around Telstra
               network, however it would assist further investigation to determine the actual location)


           3) An example of a subsurface measurement with the quality level A specified –
                                                   Telstra cover - 0.6m (QL-A)
               Where (QL-A) complies with AS5488-2013 QL-A (and is deemed suitable for excavation purposes).
               In this example the asset has been electronically located first, (QL-B) and then physically exposed (QL-A).


               Note -Telstra will seek compensation for damages caused to it its property and losses caused to Telstra and its
               customers if unvalidated subsurface measurements are used for construction and subsequently result in damage
               to Telstra assets. Only measurements conforming to AS5488-2013 (QL-A) are deemed by Telstra to be validated
               measurements.


      Rural landowners Where Telstra-owned cable crosses agricultural land, Telstra may provide on-site
       assistance with cable location. You must contact Telstra Plan Services to determine eligibility and to
       request the service.
       Please note the following –
              If eligible, the location assistance must be approved and organised by Telstra. Telstra will not pay for
               a location that has not been approved and facilitated by Telstra (Telstra is not responsible for payment
               assistance when a customer engages a locator directly).
              The exact location, including depth of cables, must be validated by potholing, which may not be covered
               by this service.
              This service is nominally only available to assist private rural land owners.
              This service nominally covers one hour on-site only, private lead-in locations are for lead-ins 100m or
               longer. Any time required in addition to Telstra-funded time can be purchased directly from the assigned
               Telstra Accredited Plant Locator.
              This service does not apply to previously located network at the same location (i.e. it is a once off).
              This service does not apply to other carriers’ cables (marked as ‘OC’ on Telstra plans).
