Unit of competency details

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 Range Statement. Assessment of performance is to be consistent with the Evidence Guide.

ELEMENT 

PERFORMANCE CRITERIA 

1 Monitor assessment of construction materials

1.3 Sources of aggregate are identified and listed, and properties of each are identified.

1.4 Any impurities in raw materials are identified and documented in accordance with relevant standards and quality assurance standards.

1.5 Raw materials  used to make concrete and concrete constructions are tested to ensure quality of finished product.

2 Supervise the handling and placement of concrete 

2.1 The effect of site access on the selection and distribution method of concrete is evaluated and documented.

2.2 Methods of distribution of concrete are listed and documented in accordance with legislative and organisational requirements.

2.3 Correct placement of level slabs, sloping slabs and vertical walls is ensured by monitoring field staff.

2.4 Reasons for, and effects of, compaction on plastic and hardened concrete are identified and listed.

2.5 Defects in concrete due to incorrect placement are identified and documented accordingly.

2.6 Finishing process and surface treatments to slab concrete are monitored and documented.

4.2 Directions given to relevant personnel  are recorded accurately.

4.3 Changes or alterations to scheduled work activities are documented accurately and communicated to relevant personnel.

Overview of assessment requirements 

A person who demonstrates competency in this unit will be able to perform the outcomes described in the Elements to the required performance level detailed in the Performance Criteria. The knowledge and skill requirements described in the Range Statement must also be demonstrated. For example, knowledge of the legislative framework and safe work practices that underpin the performance of the unit must be demonstrated.

Critical aspects of evidence to be considered 

Comply with occupational health and safety (OHS) regulations applicable to workplace operations.

Research, interpret, apply and communicate technical information.

Context of assessment 

Competency is demonstrated by performance of all stated criteria, with particular attention to the critical aspects of evidence and the knowledge and skills elaborated in the Evidence Guide, and within the scope of the Range Statement.

Assessment must take account of the endorsed Assessment Guidelines in the Local Government Training Package.

Assessment of the performance requirements in this unit should be undertaken in an actual workplace or simulated environment.

Assessment should reinforce the integration of the key competencies for the particular AQF level. Refer to the key competency levels at the end of this unit.

Relationship to other units (prerequisite or co-requisite units )

To enable holistic assessment this unit may be assessed with other units that form part of the job role.

Method of assessment 

The following assessment methods are suggested:

• observation of the learner performing a range of workplace tasks over sufficient time to demonstrate handling of a range of contingencies
• written and/or oral questioning to assess knowledge and understanding
• completion of workplace documentation
• third-party reports from experienced practitioners
• completion of self-paced learning materials including personal reflection and feedback from trainer, coach or supervisor

Evidence required for demonstration of consistent performance 

Evidence should be collected over a set period of time that is sufficient to include an appropriate range and variety of situations.

Resource implications 

The learner and trainer should have access to appropriate documentation and resources normally used in the workplace.

The Range Statement relates to the Unit of Competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised  wording in the Performance Criteria is detailed below.

Relevant standards  may include:

• industry standard specifications
• council standards
• relevant Australian standards
• quality assurance standards

Identifying concrete properties  may include:

• admixtures, including air entraining agents, set controlling types and water reducing types
• testing of mix design, including selected applications using statistics, aggregate grading and first principles
• recognising principles of reinforced concrete utilising steel, wire and fibres

Curing methods  may include:

• impermeable membrane curing
• continuously wetting concrete
• accelerated curing

Methods of testing raw materials and types of concret e may include:

• Texas ball mill test
• California bearing ratio test
• slump test
• destructive compression tests

Relevant personnel  may include:

• field staff
• contractors
• management
• office or administration staff
