Application
This unit of competency specifies the skills and knowledge required to plan, prepare and place high performance concrete onto structures requiring high strength attributes and durability.
It includes concrete work on structures including bridges, airport runways, dams, cooling towers, foundation supports for high
It applies to concreters working as members of a team with at least a moderate degree of autonomy. They would be expected to complete routine activities without close supervision.
Licensing, legislative, regulatory or certification requirements apply to this unit of competency in all states and territories except Tasmania. Relevant state and territory regulatory authorities should be consulted to confirm these requirements.
