Overview of assessment
This unit of competency could be assessed by observation of on-site operation of an excavator and the use of different attachments to complete demolition tasks on large and complex buildings, working as part of a team.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
A person should demonstrate the ability to operate an excavator from ground level to complete the following mandatory demolition tasks:
fit and secure grapples, buckets and hydraulic hammers and remove, maintain and store attachments after use
position excavator appropriately and load a truck with building rubble using a bucket
progressively and, with reference to the pre-planned and controlled sequencing of tasks outlined in the demolition plan, logically demolish all or part of three different types of buildings or structures including breaking up a concrete floor or structure using a hydraulic hammer attachment
segregating building materials effectively for recycling or disposal
a person should also demonstrate:
selection of appropriate sized machine and attachments
identification of appropriate machine (operator) protection or guarding
knowledge of the requirements, procedures and instructions for conducting demolition excavator operations
implementation of requirements, procedures and techniques for the safe, effective and efficient completion of demolition excavator operations, including:
working with others to undertake and complete demolition excavator operations that meet all of the required outcomes
consistent timely completion of demolition excavator operations that safely, effectively and efficiently meet the required outcomes.
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
relevant specifications and work instructions
plant, tools and equipment as listed appropriate to applying safe work practices
support materials appropriate to activity
workplace instructions relating to safe work practices and addressing hazards and emergencies
information relevant to each task, such as safety data sheets, work plans and approved specifications, forms and procedures manuals.
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 mandated tasks
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.
