Unit of competency

Modification History

Release 1

This version first released with CPC Construction, Plumbing and Services Training Package Release 5.0.

Supersedes and is equivalent to CPCCCO3046 Repair and rectify concrete.

Application

This unit of competency specifies the skills and knowledge required to repair and rectify defects in concrete. Repairs and rectifications include patching, refinishing, sealing or recolouring to improve aesthetic appearance, as well as more significant repairs and rectifications such as cutting and replacing sections of concrete and repairing cracks in accordance with engineer or manufacturer specifications.

The unit does not cover structural defects requiring underpinning concrete or specialist works involving highly engineered solutions.

A person who has achieved this unit of competency would be expected to take responsibility for organising and completing work tasks with a high degree of self-direction.

Licensing, legislative, regulatory or certification requirements apply to this unit of competency in some states and territories. For further information, check with the relevant regulatory authority.

Completion of the general construction induction training program, specified in the Safe Work Australia model Code of Practice: Construction Work, is required by anyone carrying out construction work. Achievement of CPCCWHS1001 Prepare to work safely in the construction industry meets this requirement.
