This competency covers the efficient delivery of quality concrete to site using an agitator or similar. It includes the operation of all ancillary equipment and the operation of plant using PLCs where appropriate. This competency is NOT intended to be used for the delivery of concrete within a site using mobile equipment or overhead cranes. PMC562070B Move materials should be used in these circumstances.

In a typical scenario the agitator will be truck mounted. This unit does not cover the driving of the truck. Local regulations should be consulted and complied with.

Typically an operator would:

deliver premix concrete to a customer.

determine the product/delivery requirements from the production schedule, specifications. delivery docket and/or other specifications.

resolve and prevent routine problems; and

ensure the delivered product is to specification.

The operator generally works independently with frequent contact with the base plant.

Required skills

Skills required for this unit include the ability to:

communicate with customers

determine, and meet customer requirements while maintaining HSE standards

deliver product to site on time and within specification

operate the equipment safely

Reading and numeracy is required to the level of interpreting workplace documents and technical information.

Required knowledge

Knowledge and understanding of the equipment sufficient to recognise problems and the appropriate action to be taken.

Knowledge of the organisation's procedures and relevant regulatory requirements along with the ability to implement them within appropriate time constraints and in a manner relevant to the operation of the equipment.

Knowledge of:

the relationship between mixing time/water cement ratio and product quality

importance of slump

quality procedures

handling techniques to maintain quality

Knowledge of underlying causes of faults such as precipitated by:

irregular mixing action

mechanical failure

electrical equipment malfunction

as is relevant to the practical operation of the equipment.

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

The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Competence must be demonstrated in the ability to recognise situations requiring action and then in implementing appropriate corrective action. Consistent performance should be demonstrated. In particular look to see that:

concrete is delivered in full, on time and in specification

there are good relations with the customers

there is good liaison with the batching plant.

These aspects may be best assessed using a range of scenarios/case studies/what ifs as the stimulus, with a walk-through forming part of the response. The assessment activities should include responding to a range of problems.

Context of and specific resources for assessment

Assessment for this unit of competency will be on an operating work site.

Assessment will occur over a range of situations which will include disruptions to normal, smooth operation.

Simulation or case studies/scenarios may be required to allow for timely assessment of parts of this competency unit (e.g., those parts of element 3 referring to dealing with customers). Simulation should be based on the actual plant and will include 'walk-throughs' of the relevant competency components. Simulations may also include the use of case studies/scenarios and role plays.

Assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations. A bank of scenarios/case studies/what ifs will be required as will a bank of questions which will be used to probe the reasoning behind the observable actions.

Method of assessment

It may be appropriate to assess this unit together with:

TLIC407D Drive heavy rigid vehicle

TLIC307C Drive medium rigid vehicle

TLIC507D Drive heavy combination vehicle

or such other unit as may be appropriate.

This unit may be assessed in conjunction with:

MSAPMSUP280A Manage conflict at work

PMC562081B Deliver customer service.

Individual enterprises may choose to add prerequisites and co-requisites relevant to their processes.

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.

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.

Procedures

All operations are performed in accordance with standard procedures and work instructions.

Special requirements

Special requirements may be noted on the docket or instructed by the batcher or otherwise communicated.

Special requirements may include the addition of water.

Relevant person

Relevant person for reporting delays/breakdowns may include batcher, dispatcher or other person as specified in the procedures.

Records

Completion of records must include:

the addition of water

other items identified in the procedures

and where possible the customer signature.

Records may be completed on the docket or other means as specified in the procedures.

Checklists

Required checklists ma include:

maintenance checklists

pre start checklists

other checklists

Context

This unit includes:

determining and adding the correct amount of water taking into account required specification and moisture/water already in the mix

measurement of slump or similar tests

customer service and product knowledge

knowledge of relevant road rules and waste disposal requirements.

It does NOT include the driving of the truck (which is a prerequisite). However the driver's road skills should be observed to ensure that they meet the business's standards.
