Unit of competency details

Unit descriptor 

This unit of competency specifies the outcomes required to produce on-site drawings of work required in buildings up to five floors with residential, commercial, industrial or mixed occupancy. Sketches may be used for estimating purposes and show measurements and other requirements for building and construction or fire, mechanical and/or plumbing services.

Application of the unit 

This unit of competency supports the needs of experienced tradespeople, project managers, estimators and builders with a responsibility for preparing sketches and drawings for scoping and estimating work.

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

ELEMENT 

PERFORMANCE CRITERIA 

1. Prepare to make sketches and drawings.

1.1. Types of drawings required  and key features to be recorded  are identified through consultation and reference to relevant job documentation and in conformity with the scope and standard practice of the relevant industry sector .

1.2. OHS requirements  on site are identified and followed.

1.3. Tools and equipment  required for inspection and measurement and for producing the drawings are gathered and checked for safety and serviceability.

2. Create simple sketches and drawings.

2.1. Inspection of the relevant area is carried out and required measurements are taken and recorded.

2.2. Any incursions into the fabric of the building for inspection and measuring purposes are made with the least amount of disruption and made good to the relevant standards and finish.

2.3. Suitable views are selected and simple sketches and drawings created using standard drawing conventions and incorporating relevant codes and standards.

2.4. Sectional drawings of structural elements are created using standard drawing conventions.

3. Notate and process drawings.

3.1. Essential information is recorded on the drawing with symbols and abbreviations according to standard drawing conventions.

3.2. Drawings are labelled, dated and processed according to organisational administration and quality procedures.

REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

Required skills 

Required skills for this unit are:

• communication skills to:

• confirm job specifications and requirements orally and in writing
• enable clear and direct communication, using questioning to identify and confirm requirements, share information, listen and understand
• read and interpret a range of documents, such as design briefs, sketches, drawings and plans
• read, interpret and apply relevant standards and codes
• use language and concepts appropriate to cultural differences
• use and interpret non-verbal communication, such as hand signals

• creative design, drawing and drafting skills, including use of drafting equipment
• drawing techniques
• numeracy skills to apply measurements and make calculations
• organisational skills, including the ability to plan and set out work
• planning skills to ensure coordinated development of sketches and drawings
• teamwork skills to work with others to action tasks and relate to people from a range of cultural and ethnic backgrounds and with varying physical and mental abilities
• technological skills to access and understand site-specific instructions.

Required knowledge 

Required knowledge for this unit is:

• drawing conventions and features, including direction, scale, key, contours, symbols and abbreviations
• requirements of relevant codes, standards, statutory and authority requirements
• safe work methods
• other services and penetrations to be considered.

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 a workplace or closely simulated 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:

• producing clear and effective drawings and sketches with appropriate notations and labelling by creating a set of sketches and drawings for a small work project in the relevant field of expertise, including:

• measurements and details of components, sub-assemblies, products and models
• correct calculations of required dimensions
• other drafting details based on measurements and other relevant information
• notations and labelling.

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:

• an induction procedure and requirement
• realistic tasks or simulated tasks covering the minimum task requirements
• relevant specifications and work instructions
• tools and equipment appropriate to applying safe work practices
• support materials appropriate to activity
• workplace instructions relating to safe working practices and addressing hazards and emergencies
• material safety data sheets
• research resources, including industry related systems information.

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:

• satisfy the endorsed Assessment Guidelines of the Construction, Plumbing and Services Training Package
• include direct observation of tasks in real or simulated work conditions, with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application
• reinforce the integration of employability skills with workplace tasks and job roles
• confirm that competency is verified and able to be transferred to other circumstances and environments.

Validity and sufficiency of evidence requires that:

• competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace
• where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice, with a decision on competency only taken at the point when the assessor has complete confidence in the person's demonstrated ability and applied knowledge
• all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence.

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.

RANGE STATEMENT
