Elements and Performance Criteria
ELEMENT |
PERFORMANCE CRITERIA |
|
1. Prepare for planning. |
1.1. Nature and scope of the planning task are identified and confirmed. 1.2. Safety (OHS ) requirements associated with installation of stormwater drainage systems and workplace environmental requirements are adhered to throughout the work. 1.3. Work is organised and sequenced in conjunction with others involved in or affected by the work. 1.4. Tools and equipment required for planning, sizing and documenting the layout of stormwater drainage systems, including personal protective equipment, are selected and checked for serviceability. 1.5. Work area in which planning process is to be conducted is prepared. |
|
2. Identify system requirements. |
2.1. Information and specifications for required work are obtained and confirmed, if necessary by site inspection. 2.2. Regulations and relevant Australian standards relevant to the work are consulted and applied to all aspects of the work. 2.3. Design criteria are determined from relevant Australian standards and proposed method of installation. 2.4. Stormwater catchment and flow requirements are identified. 2.5. Stormwater pipe size is determined to conform to regulatory authorities' main or street kerb and relevant Australian standards. 2.6. Stormwater retention pit size, silt and flotation arrestor pit size, rainwater tank size and stormwater overflow discharge locations are determined to suit job requirements. 2.7. System type is selected to suit collection and disposal requirements. 2.8. Sustainability principles and concepts are applied to work preparation and application. |
|
3. Design system layout. |
3.1. Layout of stormwater drainage system is planned in accordance with plans, specifications, relevant Australian standards, and workplace procedures. 3.2. Stormwater disposal system is specified in accordance with job requirements. 3.3. Materials required are specified and optimised from proposed design according to relevant Australian standards. 3.4. Plans are recorded in accordance with statutory and regulatory authorities' and workplace requirements. |
|
4. Restore work area. |
4.1. Work area is restored in accordance with workplace procedures. 4.2. Tools and equipment used in the process are refurbished and left in accordance with workplace procedures. 4.3. Information is accessed and documentation, including work backup, is completed in accordance with workplace requirements. |

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 providing that simulated or project-based assessment techniques fully replicate plumbing and services 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:
|
|
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:
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. |
