This unit supports the attainment of skills and knowledge required for competent workplace performance in councils of all sizes. Knowledge of the relevant legislation, codes and regulations applicable to council construction works is required. The ability to apply materials knowledge, to source appropriate raw materials and to apply relevant testing methods to raw materials and finished concrete structures must be demonstrated.

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 concrete 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.
