Licensing, legislative, regulatory or certification requirements apply to concreting work in different states and territories. Candidates are advised to consult with the relevant regulatory authorities.

Pre-Requisites

CPCCOHS2001A

Apply OHS requirements, policies and procedures in the construction industry

Employability Skills Information

This unit contains employability skills.

Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the required performance needed to demonstrate achievement of the element. Where bold italicised  text is used, further information is detailed in the required skills and knowledge and/or the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria

1

Plan and prepare.

1.1

Work instructions, work health and safety (WHS) requirements  and other information  relevant to the work are identified, confirmed and applied for planning and preparation  purposes.

1.2

Plant, tools and equipment  consistent with job requirements are selected and checked for serviceability, and faults are rectified and reported before work begins.

1.3

Material quantity requirements are identified and calculated according to plans, specifications and quality requirements .

1.4

Materials appropriate to the work application are obtained, prepared, safely handled and located ready for use.

1.5

Environmental requirements  are identified for the project according to environmental plans and regulatory requirements.

2

Apply concrete finishing techniques.

2.1

Bull float is applied immediately after initial screeding while concrete is still plastic, to assist in maintaining a level surface consistent with drawings and specifications and to remove screeding lines and inaccuracies.

2.2

Surface of concrete is assessed during the curing process and level surface is maintained to allow manual and mechanical trowelling to be applied.

2.3

Concrete is observed and left untouched until bleed water has come to the surface and evaporated.

2.4

Strength of setting concrete is assessed using a basic thumb test to ensure weight of mechanical trowel and operator can be accommodated.

2.5

Mechanical trowelling is applied and reapplied in multiple overlapping lines, to consolidate and densify the setting concrete surface.

2.6

Control joints are installed, edges finished  and concrete trowelled to specifications.

2.7

Concrete is finished  according to job specifications.

3

Clean up.

3.1

Work area is cleared and materials disposed of, reused or recycled according to regulations, codes of practice and job specification.

3.2

Plant, tools and equipment are cleaned, checked, maintained and stored according to manufacturer recommendations and standard work practices.

Required Skills and Knowledge

This section describes the skills and knowledge required for this unit.

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

This unit of competency could be assessed by undertaking a range of tasks in the workplace or a close simulation of the workplace environment, provided that simulated or project-based assessment techniques fully replicate construction workplace conditions, materials, activities, responsibilities and procedures.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

A person should demonstrate the ability to finish five different concrete surfaces, each measuring at least 100 square metres, according to job specifications.

The evidence provided should demonstrate the ability to:

  • identify the appropriate time to apply finishing concrete techniques to ensure minimal delay and waste and that finished concrete meets job specifications
  • correctly use relevant hand and power tools
  • locate, interpret and apply relevant information, standards and specifications relating to finishing concrete
  • comply with site safety plans and procedures
  • comply with organisational policies and procedures relating to finishing concrete while maintaining quality requirements outlined in job specifications
  • safely and effectively operate and use plant, tools and equipment required to finish concrete
  • communicate and work effectively and safely with others.

Context of and specific resources for assessment 

Assessment of this unit:

  • must be in the context of the work environment
  • may be conducted in an off-site context, provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills
  • must meet relevant compliance requirements.

Resource implications for assessment include:

  • an induction procedure
  • realistic tasks or simulated tasks covering the mandatory task requirements
  • relevant specifications and work instructions
  • tools and equipment appropriate to applying safe work practices
  • support materials appropriate to finishing concrete
  • workplace instructions relating to safe work practices and addressing hazards and emergencies
  • safety data sheets.

Method of assessment 

Assessment for this unit must verify the practical application of the required skills and knowledge, using a combination of the following methods:

  • direct observation of tasks in real or simulated work conditions
  • questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application
  • review of relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff.

Guidance information for assessment 

This unit could be assessed on its own or in combination with other units relevant to the job function for example:

  • CPCCCO2022A Use and maintain concreting plant, tools and equipment.

Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support.

Assessment processes and techniques should, as far as is practical, take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed.
