           o   DWF files – DWF is the default softcopy format for all requests for areas that are over 350m in
               length. Maximum length for a DWF automated response is approx 2500m - depending on geographic
               location of request (manually-processed plans may provide larger coverage). The DWF files differ
               from PDF in that DWF are vector files made up of layers that can be turned on or off and are not
               formatted to a specific sheet size. This makes them ideal for larger areas and for transmitting
               electronically.
                    How to view Telstra DWF files –
                        Telstra DWF files come with all layers turned on. You may need to turn individual layers on or
                        off for viewing and printing clarity. Individual layer names are CC (main cable/conduit), DA
                        (distribution area network) and sometimes a combined layer - CAC. Layer details can be
                        viewed by either picking off the side menu or by selecting ‘window’ then 'layers' off the top
                        menu bar. Use 'layers' to turn individual layers off or on (double click or right click on layer
                        icon).
                    How to print Telstra DWF files –
                        DWF files can be printed on any size sheet – either their entirety or by selected areas of
                        interest. Some DWF coverage areas are large and are not suited to printing legibly on a single
                        A4 sheet - you may need several prints if you only have an A4 printer. Alternatively, an A3, A1
                        or larger printer could be used. To print, zoom in or out and then, by changing the 'print range'
                        settings, you can print what is displayed on your screen to suit your paper size. If you only have
                        a small printer, e.g. A4, you may need to zoom until the text is legible for printing (which is why
                        you may need several prints). To print what is displayed on your screen the 'view' setting should
                        be changed from 'full page' to 'current view'. The 'current sheet' setting should also be selected.
                        You may need to print layers separately for clarity and legibility. (Details above on how to turn
                        layers on or off)
                    How to change the background colour from white to black (when viewing) Telstra DWF
                        files –
                        If using Autodesk Design Review the background colour can be changed by selecting ‘Tools’
                        then ‘options’ then ‘sheet’. Tick the box ‘override published paper colours’ and select the colour
                        required using the tab provided.

   STEP 2 – PREPARE
   Telstra Accredited Plant Locator (TAPL):
   Utilising a TAPL is an essential part of the process to identify network and to trace subsurface
   network prior to validating. A TAPL can provide plan interpretation, identification and electronic
   detection. This will assist in determining the position of subsurface assets prior to potholing
   (validating). Some TAPL’s can also assist in validating underground detected network. Electronic
   detection is only an indication of the existence of underground network and can be subject to
   interference from other services and local conditions. Electronic detection must not be used
   solely to determine location for construction purposes. The electronic (indicative) subsurface
   measurements must be proven by physically sighting the asset (see step 3 – Pothole ).

      All TAPL’s locating Telstra network must be able to produce a current photo ID card issued by Telstra. A list of
       TAPL’s is provided with the Telstra Dial Before You Dig plans.
      All TAPL’s in addition to the Telstra photo ID card must also have current DBYD Locator Certification with ID
       card.
      Telstra does not permit external parties (non-Telstra) to access or conduct work on Telstra network. Only Telstra
       staff, Telstra contractors or locators whom are correctly accredited are authorised to work on or access Telstra
       manholes, pits, ducts, cables etc. This is for safety as well as for legal reasons.
      The details of any contract, agreement or retainer for site assistance to locate telecommunications plant shall
       be for you to decide and agree with the Telstra Accredited Plant Locator engaged. Telstra is not a party to any
       contract entered into between you and a Telstra Accredited Plant Locator.
      Payment for the site assistance will be your responsibility and payment details must be agreed before the
       engagement is confirmed.
      Telstra does not accept any liability or responsibility for the performance of or advice given by a Telstra
       Accredited Plant Locator. Accreditation is an initiative taken by Telstra towards the establishment and
