This unit describes skills required to determine and mark the location and identity of gas, water, electrical, telecommunications and other underground utility services using a range of specialised instruments and asset plans.

This unit applies to those working as field staff with a specific responsibility for identifying the presence and exact position of utility services prior to commencing work tasks involving excavation.

The skills and knowledge described in this unit must be applied within the legislative, regulatory and policy environment in which they are carried out. Organisational policies and procedures must be consulted and adhered to, particularly those related to WHS and manufacturer specifications.

Those undertaking this unit would work under indirect supervision, while performing routine tasks, in a familiar context, ensuring minimum damage to the environment.

No licensing, legislative or certification requirements apply to unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)
