Application

This unit specifies the skills and knowledge required to use various materials to prepare subgrade, base and bedding courses in preparation for laying segmental paving. It includes identifying soil types, determining levels and grades, calculating material and screeding and compacting base materials.
This unit applies to those who pave external areas on new and existing sites. It is suitable for people operating with some autonomy. A person working at this level would be expected to take responsibility for organising and completing tasks assigned to them without needing close supervision.
Completion of the general construction induction training program specified by the model Code of Practice for Construction Work is required for any person who is to carry out construction work. Achievement ofCPCWHS1001Prepare to work safely in the construction industrymeets this requirement.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
