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 observing the demolition of a small building or structure, using hand tools, small plant and equipment.

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

A person should demonstrate the ability to:

as a minimum, given a site demolition plan and instructions, remove fixtures and fittings, a pitched metal/tiled roof, trusses, ceiling, external and internal walls, floor and floor support system of a two-storey house; and clean up, disposing or salvaging materials, ensuring:

correct identification of job requirements and conduct of the demolition process

correct selection and use of appropriate processes, tools and equipment

completion of work to specification

safe and effective operation and use of tools, plant and equipment

communication and safe work with others

compliance with regulations, standards and organisational quality procedures and processes, including:

location, interpretation and application of relevant information, standards and specifications

compliance with site safety plan and WHS legislation, regulations and codes of practice applicable to workplace operations

compliance with organisational policies and procedures, including quality requirements.

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

small plant, tools and equipment appropriate to applying safe work practices

support materials appropriate to activity

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

research resources, including industry-related systems information

safety data sheets (SDS).

Method of assessment

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

direct observation of 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.

Required skills

recognise signs indicating undiscovered hazards on a demolition site, for example termite activity

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

numeracy skills to:

check levels of lubricants in equipment

estimate weights of volumes of demolition debris and recyclable materials

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

general construction terminology

hazards associated with demolition tasks

demolition processes and techniques for small structures

procedures for material storage and environmentally friendly waste management

types of small plant, tools and equipment used in the demolition of small buildings, including:

applications

characteristics

limitations

maintenance requirements

methods of operation

quality requirements relating to the demolition of small structures

workplace and equipment safety requirements that apply to the demolition of small buildings and structures
