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 Range Statement. Assessment of performance is to be consistent with the Evidence Guide. |
Elements and Performance Criteria
ELEMENT |
PERFORMANCE CRITERIA |
1 Monitor assessment of construction materials |
1.1 Plastic and hardened concrete properties are identified and recorded in accordance with relevant standards . 1.2 Types of hydraulic cement are identified. 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. 2.7 Accurate curing methods are observed and documented. |
3 Identify faults in concrete and repair methods |
3.1 Repair methods for cracked concrete are established. 3.2 Causes of concrete faults are identified and documented accordingly. 3.3 Field staff members are instructed to repair identified faults in concrete. |
4 Maintain accurate records |
4.1 Daily diary of work undertaken and observed is updated and maintained regularly in accordance with relevant standards and organisational requirements. 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. |

Evidence Guide
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:
|
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. |
