Overview of assessment

This unit of competency could be assessed by observation of on-site operation of remote-controlled plant and the use of different attachments to complete demolition tasks on large 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 complete the following mandatory demolition tasks:

fit and secure grapples, buckets and hydraulic hammers and remove, maintain and store attachments after use

position plant 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:

knowledge of the requirements, procedures and instructions for conducting demolition remote-controlled plant operations

implementation of requirements, procedures and techniques for the safe, effective and efficient completion of demolition remote-controlled plant operations, including:

working with others to undertake and complete demolition remote-controlled plant operations that meet all of the required outcomes

consistent timely completion of demolition remote-controlled plant 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.

check levels of lubricants in equipment

perform measurements and calculations associated with work, such as when determining specified length of wall to be removed

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 tools, equipment and materials

use language and concepts appropriate to cultural differences

reading skills to:

interpret documentation relating to work requirements, including:

drawings and specifications

job safety analyses (JSA)

safe work method statements (SWMS)

safety data sheets (SDS)

understand written instructions, procedures and signage

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

Required knowledge

basic principles of structural engineering regarding loads on suspended floors

general construction terminology
