Required Skills

Required skills

Required skills include recognising potential problems and taking appropriate action implementing the enterprises standard procedures and work instructions and relevant regulatory requirements within appropriate time constraints and in a manner relevant to the operation of the equipment reading and numeracy to interpret workplace documents and technical information

Required knowledge

Required knowledge includes principles of drying of aggregates principles of mixing these products impact of variations in raw materials on final product impact of mixing on final product enterprise production schedules distinguish between causes of faults such as raw material equipment mixing timetechnique

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 material properties and mixing variables 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 product is produced on time and in specification upstream and downstream communication is timely and effective problems are anticipated and appropriate action is taken ie problem fixed or reported 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 studiesscenarios 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 walkthroughs of the relevant competency components A bank of scenarioscase studieswhat ifs and questions will be required to probe the reasoning behind observable actions
Method of assessment	This unit may be assessed in conjunction with PMCA Organise self PMC561080A Organise self MSAPMSUPA Work in a team MSAPMSUP106A Work in a team. Individual enterprises may choose to add prerequisites and corequisites relevant to their processes In remote operations this person may also need scheduling and other materials ordering and handling competencies
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
Aggregate	Aggregate may include: the normal range of gravels and sand as well as recycled asphalt pavement (RAP) It may, or may not, include the addition of special aggregates such as slag, carborundum, lime or crushed garnets
Typical problems	Typical problems may include: equipment malfunction raw material specifications mixing tolerance uniform dispersion of minor ingredients/additives mixing to special requirements matching mixes produced with production requirements adjusting mix formula to compensate for variations in raw materials (e.g. aggregate moisture content)
