Required knowledge 

• concrete additives and the effect on concrete curing, finishing and performance
• external factors affecting concrete curing, finishing and performance, and strategies for managing them, including:

• delivery temperature
• use of additives

• regulations and standards relating to concrete supply:

• AS 1379 Specification and supply of concrete
• AS 2758 Aggregate and rock for engineering purposes
• AS 3582 Supplementary cementitious materials for use with Portland cement
• AS 3600 Concrete structures
• AS 3972 Portland and blended cements

• slump-test measurements required at delivery for different concrete mixes

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 performing 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:

• assess concrete material requirements for three different types of concreting projects, including a multi-story car park; for each project, specify the types and volumes of concrete required to ensure job specifications and quality requirements are met
• prepare concrete delivery schedules
• prepare specifications for concrete supply according to workplace requirements.

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
• tools and equipment appropriate to applying safe work practices
• support materials appropriate to activity
• workplace instructions relating to safe work practices and addressing hazards and emergencies
• safety data sheets (SDS).

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.

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.

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, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Concrete material  must include:

• normal class with strength grades in the range N20 to N50
• special class with strength grades in the range S20 to S100.

Variable components and additives  may include:

• level of air entrainment
• maximum size of aggregate
• methods to ensure coolness of concrete, such as addition of liquid nitrogen
• proportion of cement.

Concrete specifications  must include:

• required temperature of concrete
• slump-test measurement, which must be:

• fit for purpose:

• ramp or slope
• slab

• consistent with:

• formwork
• placement method
• reinforcements.
