Demould concrete products

This unit of competency covers the dismantling, reassembling, lubrication and stock control of complex concrete product moulds.

Application

This unit of competency applies to operators who are responsible for removing a mould from a competed concrete product and preparing it for a new moulding operation.

This unit of competency includes:

timber, glass fibre, metal, plaster, latex rubber and other moulds

use of hand tools as required

interpretation of production schedules/work cards as appropriate

interpreting plans or specifications

the operation of all ancillary equipment.

This competency is typically performed by operators working either independently or as part of a work team. It also includes the interpretation of drawings/plans.

Required Skills

Required skills

Required skills include:

recognising conditions which will lead to mould and dies being incorrectly assembled and taking appropriate action

implementing the enterprise's procedures within time constraints and in a manner relevant to the correct use of the equipment

conveying information relevant to the operation clearly and effectively

maintaining appropriate levels of quality assurance

recognising worn moulds and parts

reading and numeracy to interpret workplace documents and technical information

Required knowledge

Required knowledge includes:

causes of mould wear

results of using worn moulds

problems resulting from mould leakage

required lubrication of mould

hazards from prestressed reinforcement

underlying causes of faults such as precipitated by:

mould

casting/operating

concrete mix

vibration

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

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

It is essential that the equipment be understood and that the importance of critical mould properties and dimensions 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:

moulds are withdrawn for repair as required

moulds drawn from the mould store are in good order

stocks of spares are kept at appropriate levels

correct moulds are available for required jobs

mould is lubricated to standard

moulds are made consistently within an appropriate timeframe and with minimum faults

good OHS practice is used consistently.

Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency.

Context of and specific resources for assessment

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.

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 unit of competency. Simulation should be based on the actual plant and will include 'walk-throughs' of the relevant competency components. A bank of scenarios/case studies/what ifs and questions will be required to probe the reasoning behind observable actions.

Method of assessment

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.


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. 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

Typical problems

Typical problems may include:

recognition of parts requiring replacement (e.g. stretched rubber, missing bolts)

selection of appropriate mould parts to replace worn parts

interpretation of drawings and matching reinforcement and moulds to drawing

Occupational health and safety (OHS)

All operations are subject to stringent OHS requirements and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and OHS requirements, the OHS requirements take precedence
