UNIT CODE

DCSGRE603

UNIT TITLE

Use graphics in engineering

APPLICATION

This unit describes the performance outcomes, skills and knowledge required to produce basic structural engineering drawings.

The unit of competency is applied by drafting personnel in a civil and structural engineering environment to produce basic drawings.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

ELEMENT

Elements describe the essential outcomes.

TITLE

Assessment requirements for DCSGRE603 – Use graphics in engineering

PERFORMANCE EVIDENCE

To achieve competency in this unit a person must satisfy the requirements of the elements and performance criteria, foundation skills and range of conditions included in the unit.

The person must also:

• utilise manual drafting equipment to produce at least 1 drawing complying with AS1100
• prepare, using CAD, at least two basic drawings of structural engineering components complying with Australian standards AS1100.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once for each criterion.

KNOWLEDGE EVIDENCE

To achieve competency in this unit a person must demonstrate knowledge of:

• interpretation and use of AS 1100
• general knowledge of various drawing approaches
• conventions used in drawing
• appropriate dimensions and views
• drawing media types and their applications
• drawing equipment maintenance

ASSESSMENT CONDITIONS

Assessment conditions:

All assessment must be completed in accordance with work health and safety standards.

When assessments are conducted remotely, invigilation software must be used to ensure authenticity of work completed.

Model answers or marking guides must be provided for all assessments to ensure reliability of assessment judgements when marking is undertaken by different assessors.

The candidate must have access to all tools, equipment, materials and documentation required.

Assessor Requirements:

Assessors must satisfy the assessor requirements in the standards for registered training organisation (RTOs) current at the time of assessment.

Assessors must also hold a tertiary qualification in engineering or related field.

Assessors must have worked for at least 3 years in industry where they have applied the skills and knowledge covered in this unit of competency.

The RTO must also ensure that trainers and assessors keep their industry knowledge up to date through ongoing professional development.

The RTO must take appropriate steps, as an ongoing procedure, to verify information about trainer and assessor’s qualifications, vocational competencies and current industry skills
