1.2 | Work health and safety (WHS) requirements are followed according to safety plans and policies. | ||
1.3 | Toolsandequipment selected to carry out tasks are consistent with job requirements, checked for serviceability, and faults are rectified and reported before work begins. | ||
1.4 | Material quantity requirements are identified and calculated according to plans, specifications and quality requirements. | ||
1.5 | Materials appropriate to the work application are obtained, prepared, safely handled and located ready for use. | ||
1.6 | Environmentalrequirements are identified for the project according to environmental plans and statutoryandregulatoryauthorityrequirements. |
2 | Produce reconstituted stone. | 2.1 | Forms or moulds are constructed, or cleaned and prepared, according to job specifications ready for placement of aggregate mix. |
2.2 | Aggregates are measured, proportioned and mixed according to job specifications. | ||
2.3 | Mould is filled with mix and light vibration is applied to consolidate material and eliminate voids. | ||
2.4 | Level of filled mould is screeded to form a flat surface and cured according to job specifications. | ||
2.5 | Reconstituted stone section is removed from mould, carefully handled and placed on table ready for grinding process. | ||
2.6 | Surface of mould is ground thoroughly to expose aggregate and voids are filled evenly with matching colour cement mortar. | ||
2.7 | Surface is polished to produce finish that is flat and free from blemish. |
3 | Clean up. | 3.1 | Area is cleared of waste material, dust and equipment according to workplace requirements. |
3.2 | Unused materials are stored and waste materials disposed of according to environmental and workplace requirements. | ||
3.3 | Tools and equipment are cleaned, maintained and stored. |

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 by observation in the workplace or simulated workplace setting. Assessment may be conducted 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 construct a terrazzo panel and repair terrazzo, marble or granite in situ, including the ability to: apply organisational quality procedures within the context of producing reconstituted stone select and use appropriate processes tools and equipment to produce reconstituted stone select stone materials consistent with job specification ensure accurate setting up of forms or moulds for placement of mix proportion materials according to specification for mix adopt and use safe and effective procedures to apply grinding and polishing processes complete produced stone to specifications for mix and finish comply with work health and safety regulations and requirements, including safe handling and placement procedures identify typical faults and problems that may occur when creating moulds, and taking necessary action to rectify them communicate with others to ensure safe and effective workplace operations. |
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 must meet relevant compliance requirements. Resource implications for assessment may include: drawings and specifications relevant to proposed tasks materials required for composition of proposed mix moulds or material for formwork appropriate to activities tools, plant and equipment appropriate to the application processes work area suitable to tasks. |
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. |
