2.4

Concrete specifications for each area and feature are specified for supplier according to project specifications and relevant standards.

3

Determine total volumes and cost of supply of different types of concrete.

3.1

Dimensions of each area or feature of concreting work are interpreted from detailed site drawings and specifications.

3.2

Volume of concrete required for each area or feature is calculated according to industry standards and workplace and project requirements.

3.3

Total volumes of concrete supply for areas and features requiring identical properties are calculated.

3.4

Total cost of required concrete is estimated according to workplace procedures.

4

Determine concrete delivery schedule.

4.1

Concrete delivery locations and site access and egress details are confirmed in consultation with relevant project personnel.

4.2

Project timelines and sequencing of work are assessed and concrete delivery schedule calculated to ensure continuous and timely supply.

4.3

Supplier specifications for volumes of different concrete mixes are developed.

4.4

Delivery schedule is confirmed with relevant project personnel, adjusted as required, and finalised for inclusion with concrete specifications.

5

Finalise specifications for concrete supply.

5.1

Specifications are reviewed and checked for accuracy of concrete mix details for different areas and features.

5.2

Individual area and feature dimensions and volume calculations are reviewed and checked for accuracy.

5.3

Total volumes of concrete supply for areas and features requiring identical properties are reviewed and checked for accuracy.

5.4

Team members and supervisor or manager are consulted for feedback on specifications, as required, according to workplace procedures.

5.5

Supplier specifications are processed according to workplace procedures.

5.6

Concrete order including delivery schedule is placed with supplier and order acceptance is confirmed.

Evidence Required

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.


Range Statement

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.
