  IMPORTANT:
  When working in the vicinity of telecommunications plant you have a "Duty of Care" that must be observed.
  Please read and understand all the information and disclaimers provided below.
  Telstra network is complex and requires expert knowledge to interpret information, to identify and locate
  components, to pothole underground assets for validation and to safely work around assets without
  causing damage. If you are not an expert and/or qualified in these areas, then you must not attempt these
  activities. Telstra will seek compensation for damages caused to its property and losses caused to Telstra
  and its customers.

  The 5 P’s to prevent damage to Telstra assets are listed below. Construction activities must not commence
  without first undertaking these steps. If you are designing a project it is recommended that you also
  undertake these steps to validate underground assets prior to committing to your design.

  (The following pages contain more detail on each step below and the contact details to seek further advice.
  AS5488-2013 is the Australian Standard for the Classification of Subsurface Utility Information.)

  1    PLAN:
       The essential first step in preventing damage -
       You must have current Telstra plans via the DBYD process. Telstra advises that the accuracy of the
       information provided by Telstra conforms to Quality Level D as defined in AS5488-2013. This means the
       information is indicative only, not a precise location. The actual location may differ substantially from that
       shown on the plans - refer to steps 2 & 3 to determine actual location prior to proceeding with construction.

  2    PREPARE:
       The essential second step in preventing damage -
       Engage a Telstra Accredited Plant Locator. To be able to trace and identify individual subsurface cables and
       ducts requires access to Telstra pits and manholes. Only a Telstra Accredited Plant Locator (TAPL) is
       authorised to access Telstra network for locating purposes. A TAPL can interpret plans, validate visible assets
       and access pits and manholes to undertake electronic detection of underground assets prior to further
       validation. All Telstra assets must be located, validated and protected prior to commencing construction. If
       you are not authorised to do so by Telstra, you must not access Telstra network or locate Telstra network. All
       Telstra Accredited Plant Locators are required to have DBYD Locator Certification.

  3 POTHOLE:
       The essential third step in preventing damage -
       All Telstra assets must be positively identified (i.e. validated), by physically sighting them. For underground
       assets this can be done by potholing by hand or using non-destructive vacuum extraction methods (Refer to
       ‘validation’ as defined in AS5488-2013 QL-A). Underground assets located by electronic detection alone
       (step 2), are not deemed to be ‘validated’ and must not be used for construction purposes. Some
       TAPL’s can assist with non-destructive potholing for validation purposes. If you cannot validate the Telstra
       network, you must not proceed with construction. Telstra will seek compensation for damages caused to
       its property and losses caused to Telstra and its customers.

  4 PROTECT:
       The essential fourth step in preventing damage -
       Telstra assets must be protected to avoid damage from construction activities. Minimum working distances
       around Telstra network must be maintained. These distances are provided in this document. Telstra can also
       provide advice and assistance in regards to protection – refer to the following pages.

  5 PROCEED:
       Only proceed when the above steps have been completed.
