Electricity Entity Requirements:
Working Near Overhead and Underground Electric Lines

6.3.2       Location of underground electrical assets
Examining the records is not sufficient, as reference points may change from the time of
installation. Records must also be physically proven when working in close proximity to
underground electrical assets. The exact location of underground electrical assets likely to be
affected shall be confirmed by use of an electronic cable locator followed by careful non
mechanical excavation to the level of concrete slabs or conduits. Non mechanical excavation
(potholing using hydrovac or hand tools) must be used in advance of excavators. In any case,
where doubt exists with respect to interpretation of cable records, contact the Electricity Entity
(General Enquiries phone number - refer page 3) for further advice.
       If during excavation, cables or conduits are damaged:
               call Electricity Entity (Emergencies phone number – refer page 3) to report
                damaged cables or conduits.
               treat cables as if alive, post a person to keep all others clear of the excavation until
                the Electricity Entity crew attend to make safe.
       If unknown cables or conduits (e.g. not shown on issued DBYD plans) are located during
        excavation:
               call Electricity Entity (Emergencies phone number – refer page 1) to report.
               treat cables as if alive, post a person to keep all others clear of the excavation until
                the Electricity Entity crew attend to make safe.
       If the constructor is unable to locate Electricity Entity underground electrical assets within
        2.5 m of nominal plan locations, they should contact the Electricity Entity (General
        Enquiries phone number - refer page 3) for further advice.

6.3.3       Remote or On-Site Cable Location conducted by Electricity Entity
This service shall only be provided at Electricity Entity’s discretion:
       The Electricity Entity may provide this site visit only when underground cables (33 kV or
        above) are present.
       Due to remote locations where external cable locator or hydro vac service providers are
        not readily available, Electricity Entity may attend site and assist with cable location (fees
        may apply for this service).
       The Electricity Entity may provide either remote over the phone or on-site cable location
        advice to assist in the location of Electricity Entity underground electrical assets, including
        how to visually locate and protect the plant when excavating.
       Where the Electricity Entity provides on-site cable location advice, any markings provided
        for the purpose of identifying cable location are for general guidance only, and the
        constructor is still responsible for non-mechanical excavation (potholing using hydrovac or
        hand tools) to visually locate Electricity Entity underground electrical assets.
       If the constructor is unable to locate Electricity Entity underground electrical assets within
        2.5 m of nominal plan locations, they should contact Electricity Entity (General Enquiries
        phone number - refer page 3) to request further advice.
