Description
This unit of competency covers the conducting of benching operations and the production of special purpose concrete, clay or refractory components. It involves ensuring the mould is correctly assembled, selecting the necessary tools and materials, ensuring correct inserts are available and ensuring finished product is to specification.
Notes
Elements and Performance Criteria
1. Determine the shape of the work piece
  • 1.1. Check the specification, drawing or client instructions
  • 1.2. Calculate the angle of decline to be applied to the work piece
  • 1.3. Determine the number of access and egress points to facilitate movement of liquids through the work piece
  • 1.4. Identify and obtain components, reinforcing and/or other fitments as required by the specification.
2. Assemble and prepare the work piece
  • 2.1. Establish a safe working environment which meets occupational health and safety (OHS) and enterprise requirements
  • 2.2. Identify and prepare the appropriate liner or cover
  • 2.3. Secure and level in accordance with procedures/work instructions
  • 2.4. Check that the base is stabilised and correctly mounted as required to facilitate lifting or moving
  • 2.5. Position components, reinforcing and/or other fitments as required by the specification
3. Rough cast the work piece
  • 3.1. Prepare the concrete mix or obtain the material from the batch preparation unit
  • 3.2. Ensure an adequate supply of material is available to meet production requirements
  • 3.3. Free form the concrete inside the work piece to meet the rough dimensions required by the specification
  • 3.4. Ensure that components, reinforcing and/or other fitments do not move during rough casting
  • 3.5. Employ safe working practices which conform to OHS and enterprise requirements
4. Finish the work piece
  • 4.1. Prepare a finishing mixture for application to the work piece
  • 4.2. Apply the finishing coating, trowelling and sleeking the surface to specification
  • 4.3. Ensure the work piece cures according to procedures/work practices
  • 4.4. Remove any separators, non-permanent inserts, plugs or blinds
  • 4.5. Release work piece in accordance with safe working practice and procedures
  • 4.6. Return mould segments for reuse or storage in accordance with enterprise storage quality requirements
5. Rectify routine problems
  • 5.1. Identify the range of faults that can occur during the operation
  • 5.2. Determine and rectify fault causes procedures/work instructions
  • 5.3. Identify and rectify equipment failure causes in accordance with procedures/work instructions
  • 5.4. Ensure appropriate records and log books of equipment operations are maintained to meet procedures/work instructions
  • 5.5. Identify non-routine problems and report to designated person
6. Inspect and store products
  • 6.1. Inspect work piece for defects
  • 6.2. Make allowable repairs in accordance with specifications and procedures/work instructions
  • 6.3. Identify and mark work piece with appropriate brand or identification number
  • 6.4. Apply appropriate surface coatings or coverings as required by the specification
  • 6.5. Move work piece and store in compliance with enterprise storage quality/quantity requirements
7. Control hazards
  • 7.1. Identify hazards from the job to be done
  • 7.2. Identify other hazards in the work area
  • 7.3. Assess the risks arising from those hazards
  • 7.4. Implement measures to control those risks in line with procedures
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:
maintaining correct sectional thicknesses and distribution of materials
maintaining sectional profiles in accordance with specification
correctly selecting and positioning/securing permanent or non-permanent inserts, plugs or blinds, and/or reinforcing in moulds
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
EVIDENCE GUIDE
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 and process be understood and that the importance of critical material properties is known. Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in reporting the condition to the appropriate individual.
Consistent performance at the required standard should be demonstrated. In particular look to see that:
types of concrete and finishing materials are able to be identified
OHS and safe work practices are followed
work piece transfer movements are monitored and appropriate safe working practices employed
basic maintenance and inspection practices are carried out.
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.
