Elements and Performance Criteria

Context
This competency may be used to top up and finish manufactured concrete products to specification. It incorporates the positioning and fitting of accessories and reinforcement of these products before they have been cured, and veneering.
This competency unit includes -
matching concrete to specification
fitting accessories and reinforcing
veneering.
Typical accessories include -
hooks
pipes
rubber tubing.
Typical veneering includes -
screeding
floating
helicopter floating
brushing.
This competency includes the operation of all ancillary equipment and the operation of plant using PLCs where appropriate.
All operations are performed in accordance with standard procedures and work instructions.

OHS
The identification and control of hazards and the application of OHS is to be in accordance with current, applicable legislation and regulations, and company procedures. All work is carried out at all times in accordance with these requirements.

Assessment context and methods
Competence in this unit may be assessed by observation over time on an operating plant. Where this is done, the timeframe must allow for adequate assessment of operation under all normal and a range of abnormal conditions. Where this is not practical, additional assessment techniques must be used.
Competence may also be assessed by use of a suitable simulation and/or a range of case studies/scenarios. A combination of these techniques should be used to ensure the competency is adequately assessed.
In all cases it is expected that the practical assessment will be supported by targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in such a manner as is appropriate to the language and literacy levels of the operator and reflecting the requirements of the competency.

Critical aspects
It is essential that the process be understood and that the importance of critical material properties, mixing variables, topping up and fitting of accessories is known. Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action.

Consistent performance should be demonstrated. In particular look to see that:

reinforcing is fitted according specification
accessories are fitted as required by work instructions
moulded product is level, according to specification.
Competence must be demonstrated in the operation of all ancillary equipment to the level required for this competency unit.

Resource implications
Resources required include suitable access to an operating plant or equipment which allows for appropriate and realistic simulation. A bank of case studies/scenarios will also be required where these form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunch room. No other special resources are required.

Essential knowledge and enterprise requirements
Knowledge and understanding of concrete and of the topping up and finishing process sufficient to recognise problems and take appropriate action.
Knowledge of the enterprise's standard procedures and work instructions and relevant regulatory requirements along with the ability to implement them within appropriate time constraints and in a manner relevant to the mixing and application of coloured cement.

Competence includes the ability to:


apply and/or describe:

principles of concrete mixing
principles of reinforcing concrete to specification
principles of fitting accessories to specification
principles of concrete product finishing

distinguish between causes of faults such as:

material
mixing
application
finishing
as is relevant to the practical operation of the equipment/process/system.
