Elements and Performance Criteria
1 | Plan and prepare. | 1.1 | Work instructions, work health and safety (WHS) requirements and other information relevant to the work are identified, confirmed and applied for planning and preparation purposes. |
1.2 | Plant, tools and equipment consistent with job requirements are selected and checked for serviceability, and faults are rectified and reported before work begins. | ||
1.3 | Material quantity requirements are identified and calculated according to plans, specifications and quality requirements. | ||
1.4 | Materials appropriate to the work application are obtained, prepared, safely handled and located ready for use. | ||
1.5 | Environmental requirements are identified for the project according to environmental plans and regulatory requirements. |
2 | Apply concrete finishing techniques. | 2.1 | Bull float is applied immediately after initial screeding while concrete is still plastic, to assist in maintaining a level surface consistent with drawings and specifications and to remove screeding lines and inaccuracies. |
2.2 | Surface of concrete is assessed during the curing process and level surface is maintained to allow manual and mechanical trowelling to be applied. | ||
2.3 | Concrete is observed and left untouched until bleed water has come to the surface and evaporated. | ||
2.4 | Strength of setting concrete is assessed using a basic thumb test to ensure weight of mechanical trowel and operator can be accommodated. | ||
2.5 | Mechanical trowelling is applied and reapplied in multiple overlapping lines, to consolidate and densify the setting concrete surface. | ||
2.6 | Control joints are installed, edges finished and concrete trowelled to specifications. | ||
2.7 | Concrete is finished according to job specifications. |
3 | Clean up. | 3.1 | Work area is cleared and materials disposed of, reused or recycled according to regulations, codes of practice and job specification. |
3.2 | Plant, tools and equipment are cleaned, checked, maintained and stored according to manufacturer recommendations and standard work practices. |
