Overview of assessment 

This unit of competency could be assessed in the workplace or simulated workplace setting. Assessment shall be while tasks are undertaken either individually or as part of a team under limited supervision.

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

A person should demonstrate the ability to build two different types of stone arches and provide evidence of:

• complying with work health and safety requirements applicable to workplace operations
• complying with organisational policies and procedures
• selecting and using tools and equipment to carry out arch construction process
• applying organisational quality procedures and processes within the context of constructing stone arches to walls or columns
• adopting and using safe and effective procedures to set out and set up arch centre to specification
• giving particular attention to support of centre and method of lowering when arch is complete
• identifying and, where applicable, marking each cut stone for arch location
• using safe and effective procedures to handle and place each stone
• forming arch to specification and, where applicable, applying mortar to joints
• identifying typical faults and problems that occur and taking necessary action to rectify them
• communicating with others to ensure safe and effective workplace operations
• completing arch construction, including finish to specifications.

Context of and specific resources for assessment 

Assessment of this unit:

• must be in the context of the work environment
• may be conducted in an off-site context, provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills

Resource implications for assessment may include:

• drawings and specifications relevant to proposed activity
• hand and power tools, plant and equipment appropriate to construction processes
• materials relevant to proposed activity
• scaffolding appropriate to construction processes
• site location for proposed activity.

Method of assessment 

Assessment for this unit must verify the practical application of the required skills and knowledge, using one or more of the following methods:

• direct observation of tasks in real or simulated 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.
