Application of the Unit

This unit of competency applies to a person working at paraprofessional level in a civil engineering environment where stormwater reticulation drawings are prepared.





Elements describe the essential outcomes of a unit of competency. Elements describe actions or outcomes that are demonstrable and assessable.


Performance criteria describe the required performance needed  to demonstrate achievement of the element – they identify the standard for the element. Where bold / italicized text is used, further information or explanation is detailed in the required skills and knowledge and/or the range statement.

Assessment of performance is to be consistent with the evidence guide.

1. Identify stormwater reticulation scheme to be drawn

  • Occupational Health and Safety /Workplace Health and Safety (OHS/WHS) requirements and environmental requirements for a given work area are determined.
  • Established OHS/WHS requirements and risk control measures and procedures are followed in preparation of the work
  • Existing drawings, relevant documentation and work requests are sought and discussed with appropriate personnel.
  • Appropriate personnel are consulted to ensure the work is co-ordinated effectively with others involved at the work site.
  • Resources and equipment needed for the task are obtained in accordance with enterprise procedures and checked for correct operation and

2. Plan drafting approach

  • Project specifications and related documentation required for the drawing project is collected and analysed.
  • Design references and equipment are set up to complete the drawings in accordance to the manufacturer’s manuals and enterprise procedures.

3. Complete the drawings

  • Drafting references and equipment are used according to manufacturer’s manuals and enterprise procedures.
  • Survey data is analysed and required calculations are performed
  • Decisions for dealing with unexpected situations are made from discussions with appropriate personnel, job specifications and enterprise
  • Methods for dealing with unexpected situations are selected on the basis of safety and specified work outcomes.
  • Drawings are completed to conform with AS1100.401, State and local council regulations and in accordance with enterprise
  • Final drawings are reviewed with appropriate personnel against job specifications and amended as

4. Present and archive drawings

  • Drawings are presented and discussed with appropriate personnel in accordance with enterprise procedures
  • Drafting references and equipment are maintained and stored in accordance with enterprise
  • Drawings are stored and archived according to enterprise procedures.



This describes the essential skills and knowledge and their level required for this unit.

The evidence guide provides advice on assessment and must be read in conjunction with the Elements, Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment section in Section B of the Accreditation Submission.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

  • Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the associated performance criteria, including required skills and knowledge. Specifically they must be able to:
    • implement OHS/WHS procedures and practices including the use of risk control measures as specified in the performance criteria
    • demonstrate the ability to produce drawings for a stormwater reticulation scheme in accordance with AS 1100.401 and job specifications on more than one occasion and in different contexts.

Context of and specific resources for assessment

  • This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate
  • Resources required for assessment include:
    • OHS/WHS policy and work procedures and
    • access to workplace or work real environment and a variety of conditions
    • operational access to manual or computer aided drafting equipment manufacturer’s manuals and consumables
    • access to relevant plans, drawings, job instructions topographical information, survey data and any other relevant information required for the production of the drawings.




Methods of assessment

  • Evidence must involve demonstration of practical skills and may also include:
  • For valid and reliable assessment of this unit, evidence should be gathered through a range of methods to indicate consistent performance.
    • observation of processes and procedures
    • oral and/or written questioning on required knowledge and skills
    • testimony from supervisors, colleagues, clients and/or other appropriate persons
    • inspection of the final product or outcome
    • a portfolio of documented
  • Where performance is not directly observed any evidence should be authenticated by colleagues, supervisors, clients or other appropriate 
  • Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.
