Produce structural precast concrete
Assessment tool
Version 1.0
Issue Date: April 2024
This unit of competency applies to operators in a concrete plant who are responsible for producing precast structural concrete components for a variety of structural uses. This competency includes the operation of all ancillary equipment. It includes reinforcement preparation, and the operation of casting and vibrating equipment. Reinforcement and vibration at this level of competency may be quite complex (e.g. formwork techniques, deflected strands, jig reinforcement, end block reinforcement).
This unit of competency includes:
placement of reinforcing, placement and stressing of strands
compaction using form vibrators, vibrating tables and immersion vibrators as appropriate to the enterprise
curing by water, steam, membrane or other heat sources as appropriate to the enterprise
specialised formwork techniques which could involve polystyrene blocks to lighten heavy products
deflected strands
jigging reinforcement
end block reinforcement
welding.
This competency is typically performed by an experienced operator, leading hand or supervisor, and would generally involve engineer consultation.
This unit of competency covers the production of structural precast and prestressed concrete products such as beams and girders. It involves preparing the mould and assembling the reinforcing, ensuring quality of concrete, monitoring the process and removing the work piece from the mould.
