Required knowledge for this unit is: AS3700 Masonry in buildings Building Code of Australia (BCA) requirements relevant to stonemasonry work common finishes used for mortar in masonry commonly used range of mortar additives, including plasticisers and their application interpretation of work drawings and specifications job safety analysis (JSA) and safe work method statements measuring and levelling processes relevant to stonemasonry work mortar mix types and composition techniques for laying and securing stone types of stone and their characteristics types of stone wall construction workplace and equipment safety requirements. |
Evidence Required
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 in the workplace or a close simulation of the workplace environment, provided that simulated or project-based assessment techniques fully replicate construction workplace conditions, materials, activities, responsibilities and procedures. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | A person who demonstrates competency in this unit must be able to construct three stone walls using different types of stone materials listed in the range statement, providing evidence of the ability to: comply with OHS regulations applicable to workplace operations display compliance with organisational policies and procedures, including quality assurance requirements within the context of laying stone select and use appropriate processes, tools and equipment to carry out tasks demonstrate sound techniques in preparing mortar display sound and safe application methods to handle stone demonstrate sound techniques in laying stone to line, level, plumb or to designed alignment select and use sound techniques to finish stone face to specification communicate with others to ensure safe and effective workplace operations. |
Context of and specific resources for assessment | This competency is to be assessed using standard and authorised work practices, safety requirements and environmental constraints. Assessment of essential underpinning knowledge will usually be conducted in an off-site context. Assessment is to comply with relevant regulatory or Australian standards' requirements. Resource implications for assessment include: workplace location appropriate tools, plant and equipment scaffolding where applicable materials suitable to the task relevant drawings, specifications and documentation. 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. |
Method of assessment | Assessment methods must: satisfy the endorsed Assessment Guidelines of the Construction, Plumbing and Services Training Package include direct observation of tasks in real or simulated work conditions, with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application reinforce the integration of employability skills with workplace tasks and job roles confirm a reasonable inference that competency is not only verified under the particular assessment circumstance, but is able to be transferred to other circumstances and environments. Validity and sufficiency of evidence requires that: competency will need to be demonstrated over a period of time reflecting the scope of the role and practical requirements of the workplace where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice with a decision on competency only taken at the point when the assessor has complete confidence in the person's demonstrated ability and applied knowledge all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence. 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. Supplementary evidence of competency may be obtained from relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff. |
