Application
This unit specifies the skills and knowledge required to construct various types of masonry arches within walls and above columns or attached piers.
This unit applies to bricklayers and blocklayers who construct masonry arches in new or existing structures. 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 of CPCCWHS1001 Prepare to work safely in the construction industry meets this requirement.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Pre-requisite Unit
CPCCWHS2001 Apply WHS requirements, policies and procedures in the construction industry
