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

This unit of competency could be assessed by observation of the operation of a crushing plant in the workplace.

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

A person should demonstrate the ability to crush a minimum of 100 tonnes of demolition material into two different nominal sizes of crushings, which may be 5mm, 10mm, 20mm or 40mm, including:

communicating and working effectively and safely with others

completing work to specification

complying with site safety plan and requirements of:

organisational procedures and processes, including quality requirements

standards and codes of practice applicable to the operation of a demolition materials crushing plant

WHS legislation and regulations

identifying work requirements

safely and effectively operating plant, and using tools and equipment.

Context of and specific resources for assessment

Assessment of this unit:

must be in the context of the work environment

must meet relevant compliance requirements.

Resource implications for assessment include:

an induction procedure

realistic tasks covering the mandatory task requirements, including a crushing schedule and work instructions

research resources, including industry-related systems information

support materials appropriate to activity, including:

relevant manuals and specifications

safety data sheets

tools and equipment appropriate to applying safe work practices

workplace instructions relating to safe work practices and addressing hazards and emergencies.

Method of assessment

Assessment for this unit must verify the practical application of the required skills and knowledge, using a combination of the following methods:

direct observation of tasks in real work conditions

questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application

review of relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff.

Guidance information for assessment

This unit could be assessed on its own or in combination with other units relevant to the job function.

Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support.

Assessment processes and techniques should, as far as is practical, take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed.

Required skills

learning skills to:

evaluate own actions and make judgements about performance and necessary improvements

respond to change, such as differences in current work site environmental and sustainability requirements

numeracy skills to:

estimate weight of volumes of demolition debris

perform measurements and calculations associated with work, such as determining maximum load capacity of equipment

oral communication skills to:

enable clear and direct communication, using questioning to identify and confirm requirements, and share information

report hazards on the work site, including faults in equipment

use language and concepts appropriate to cultural differences

reading skills to:

interpret documentation, including drawings

understand written instructions, procedures and signage, such as:

job safety analyses (JSA)

safe work method statements (SWMS)

safety data sheets (SDS)

writing skills to complete pre-operational checklists and equipment fault forms

Required knowledge

construction terminology

procedures for material storage and environmentally friendly waste management

quality requirements relating to products of crushing operations

types, characteristics, uses and limitations of plant and equipment involved in the conduct of crushing operations, including:

hazards associated with the conduct of crushing operations

method of operation and maintenance requirements of crushing plant and equipment

techniques associated with the conduct of crushing operations

workplace and equipment safety requirements that apply to the operation of a demolition material crushing plant
