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 CPCCCO3041 Place concrete.

Application

This unit of competency specifies the skills and knowledge required to place concrete into prepared formwork or foundations. It includes receiving and checking concrete against specifications, calculating the required volume of concrete, moving concrete from the truck to the pour location, and placing and screeding concrete.

A person who has achieved this unit of competency would be expected to take responsibility for organising and completing these 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.

Pre-requisite Unit

1.6

Select plant, tools and equipment, check for serviceability and rectify or report any faults.

1.7

Select and fit required personal protective equipment (PPE).

2

Prepare location for concrete placement.

2.1

Inspect work site, assess hazards and apply risk controls including required signage and barricades around pour location.

2.2

Determine location for concrete placement from specifications.

2.3

Discuss implications for concrete placement near existing structures with relevant persons and define separation or connection requirements.

2.4

Check that location for placement is free of debris and waste.

2.5

Ensure site access is clear to allow concrete to be received.

3

Receive concrete.

3.1

Check concrete delivery docket for accuracy against order.

3.2

Direct concrete delivery vehicle to location of discharge.

3.3

Identify slump tolerance against specifications and relevant standards for minimum grade.

3.4

Monitor concrete discharged via chute into appropriate receptacle and communicate with relevant persons to maintain safety and quality in accordance with workplace requirements.

4

Carry out concrete placement activities.

4.1

Use required plant, tools and equipment to place concrete in horizontal layers into location in accordance with indicated levels.

4.2

Ensure vertical drop of concrete is less than two metres to avoid segregation of concrete materials.

4.3

Consolidate poured concrete using required compaction or vibration method.

4.4

Carry out measurements and calculations throughout pour to ensure sufficient concrete is delivered to fill placement area, and place order for any shortfall in accordance with workplace requirements.

4.5

Check finished levels against datum using levelling device and rectify incorrect levels.

4.6

Screed concrete to required levels and grades in accordance with specifications.

5

Clean up.

5.1

Clear work area and dispose of, reuse or recycle materials in accordance with regulatory and workplace requirements.

5.2

Clean, check, maintain and store plant, tools and equipment in accordance with manufacturer and workplace requirements.

Foundation Skills

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.

Assessment requirements

Modification History

Release 1

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

Supersedes and is equivalent to CPCCCO3041 Place concrete.

Performance Evidence

To demonstrate competency, a candidate must meet the elements and performance criteria of this unit by placing concrete in either a non-precast work environment or a precast work environment:

  • for the non-precast work environment, placing concrete at five different sites:
  • each site must measure at least 100 square metres
  • one site must include a fall of at least 25 millimetres over 1 metre in distance
  • for the precast work environment, on five different occasions, placing concrete for a minimum of three panels involving more than one truck load of concrete.

Knowledge Evidence

To be competent in this unit, a candidate must demonstrate knowledge of:

  • basic science of concrete involving cement chemical reaction (hydration) dependent on water content, temperature and time:
  • effect on plastic state performance:
  • benefits and non-benefits of admixture types and doses
  • plastic shrinkage cracking risk
  • effect on hardened state performance:
  • early age and later age strength development
  • drying shrinkage and cracking
