Elements and Performance Criteria Pre-Content
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the tasks you need to be able to perform, to demonstrate that you can achieve the element. Where bold italicised text is used, further information is detailed in the range statement. Assessment of performance is to be consistent with the evidence guide. |
Elements and Performance Criteria
1 Clarify and confirm design requirements |
1.1 Review concept proposal to identify system requirements. 1.2 Identify constraints and parts of the concept proposal requiring clarification or with design problems. 1.3 Identify stakeholders and evaluate and negotiate alternative options to resolve problems. 1.4 Confirm design standards and specifications relevant to the pressure sewerage system. 1.5 Define and document detailed design requirements. 1.6 Identify and apply initial data to the design. |
2 Prepare pressure sewerage system design |
2.1 Review project design requirements prior to proceeding with detailed design. 2.2 Prepare designs for pressure sewer systems to meet project design requirements and design standards, codes and specifications. 2.3 Design to allow for required land use. 2.4 Determine contributing flows and pumping rates. 2.5 Determine pipe sizes. 2.6 Finalise horizontal alignment and pipeline levels in accordance with project design requirements and design standards and specifications. 2.7 Determine appropriate pipe materials. 2.8 Design and layout on-property pressure sewer components. 2.9 Design collection pump units and emergency storage requirements to meet project design requirements and design standards and specifications. 2.10 Design to make allowance for OHS during construction and in service life. 2.11 Prepare design drawings in accordance with design standards, codes and Water Agency requirements. |
3 Manage documentation |
3.1 Prepare supporting documentation in accordance with legislative and organisation requirements . 3.2 Maintain engineering and project records in accordance with legislative and organisation requirements. |
4 Evaluate design |
4.1 Review design to ensure objectives and specifications have been met. 4.2 Identify and evaluate compliance with environmental standards and impacts of the design. 4.3 Identify and evaluate compliance with legislation, codes and standards including OHS. 4.4 Investigate and assess alternative design options. 4.5 Recommend the most appropriate design proposal for adoption. |

Overview of assessment |
The candidate should:
|
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
The candidate should demonstrate the ability to design pressure sewerage systems including:
|
Context of and specific resources for assessment |
Access to the workplace and resources including:
Where applicable, physical resources should include equipment modified for people with disabilities. Access must be provided to appropriate learning and assessment support when required. |
Method of assessment |
The following methods are suggested:
|
Guidance information for assessment |
Assessment processes and techniques must be culturally appropriate, and appropriate to the language and literacy capacity of the candidate and the work being performed. Validity and sufficiency of evidence require that:
In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in a manner appropriate to the skill levels of the operator and cultural issues that may affect responses to the questions, and will reflect the requirements of the competency and the work being performed. |
