Elements and Performance Criteria
ELEMENT |
PERFORMANCE CRITERIA |
1. Plan and prepare. |
1.1. Work instructions and operational details are obtained using relevant information , confirmed and applied for planning and preparation purposes. 1.2. Safety (OHS ) requirements are followed in accordance with safety plans and policies. 1.3. Signage and barricade requirements are identified and implemented. 1.4. Tools and equipment selected to carry out tasks are consistent with the requirements of the job, checked for serviceability and any faults are rectified or reported prior to commencement. 1.5. Material quantity requirements are calculated in accordance with plans and specifications and quality requirements . 1.6. Materials appropriate to the work application are identified, obtained, prepared, safely handled and located ready for use. 1.7. Environmental requirements are identified for the project in accordance with environmental plans and regulatory obligations and applied. |
2. Prepare work area. |
2.1. Area to be waterproofed is identified from plans and specifications. 2.2. Surface to be waterproofed is inspected and tested to determine appropriateness of the installation and any contaminants, moisture or incompatible materials. 2.3. Ventilation is provided in accordance with material safety data sheets (MSDS). 2.4. Run-off and environmental controls are provided in accordance with regulatory and workplace requirements. 2.5. Work area is prepared for the waterproofing processes in accordance with manufacturer specifications. 2.6. Surface mounted wet area construction units, fixtures and attachments are detached, removed or arranged for removal from the work area and stored. 2.7. Building structure service penetrations, cavities or knockout sections are cleaned of unwanted materials or debris in accordance with good building practice. 2.8. Cross cavity flashings and overlapping are inspected for damage and fitness for purpose. 2.9. Work surface of the building structure is cleaned free of unwanted materials in accordance with good building practice. |
3. Prepare and repair substrate. |
3.1. Surface or area to be prepared and repaired is assessed for defects to ascertain responsibility for repair, referring areas of concern to supervisor or structural engineer. 3.2. Tools are selected to prepare and repair the surface consistent with surface condition and work to be undertaken. 3.3. Appropriate tools are used and applied safely to remove loose or protruding material to specification. 3.4. Surface is prepared for repair in accordance with manufacturer specifications and workplace procedures. 3.5. Method of repairing surface defects is determined in accordance with manufacturer specifications and is consistent with type of material surface, size of defect, compatibility of materials and specified finish. 3.6. Repair medium materials are selected, prepared and applied in accordance with manufacturers' and supervisor or structural engineer specifications and consistent with type of material, surface, size of defect, compatibility of materials and specified finish. 3.7. Appropriate water stops/hobs and bond breakers/fillets are installed in accordance with manufacturer specifications, drawings and finish levels. 3.8. Substrate to be waterproofed is prepared to manufacturer specification. 3.9. Substrate is prime coated with waterproofing material in line with manufacturer specification. 3.10. Primed surface area is cleaned free of unwanted materials to provide a smooth and uniform surface in accordance with specifications, manufacturer recommendations and good building practices. 3.11. Surface is protected until the application of the waterproof membrane in accordance with workplace procedures. |

Evidence Guide
EVIDENCE GUIDE |
|
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 provide evidence of the ability to:
|
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:
Assessment of this unit of competency may be in conjunction with assessment of other units commonly performed at the same time in normal job roles. 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:
Validity and sufficiency of evidence requires that:
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. |
