Unit Descriptor

Unit descriptor 

This unit covers the skills and knowledge required to interpret design related information required for the commencement of a structural steel detailing project.

Application of the Unit

Application of the unit 

This unit applies to the initial receiving and checking of design related information by structural steel detailers including obtaining additional information or clarifying information already received. Structural steel detailers must obtain and interpret design related information from architects and consulting engineers in order to carry out structural steel detailing. The unit may apply to structural steel detailing carried out for residential, commercial, industrial or mining fabrication and construction projects.

The unit assumes that knowledge of basic technical drawing conventions and procedures such as view, dimensioning, drawing layout, etc. is already held.

Work is conducted according to defined procedures.

Work may be conducted in small to large scale enterprises and may involve individual and team activities.

This unit requires the application of skills associated with planning and organising to complete structural steel detail drawings. Communication and numeracy skills are used to refer to patterns and specifications and complete and label sketches. Self management skills are used to ensure conformance of own work to quality standards.

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 

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

Demonstrates skills and knowledge to:

  • identify and interpret architect and engineer design specifications for structural steel constructions including constructions with suspended floors
  • relate design information to structural steel detailing processes including checking of adequacy of design information for the construction
  • establish efficient administrative arrangements for liaison with designers including arrangements for formal requests for further information
  • establish drawing and document control procedures

Context of and specific resources for assessment 

Assessment may occur on the job or in an appropriately simulated environment

Resource implications for this unit include:

  • access to real or appropriately simulated detailing of structural steel constructions including provision of suitable design information
  • computer with suitable CAD software or manual drafting equipment and material including work areas, materials and equipment
  • access to steel and component manufacturers' catalogues or websites
  • access to relevant standards through either hard copy or internet access.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

Method of assessment 

  • Assessment must satisfy the endorsed assessment guidelines of the Manufacturing Training Package
  • Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge
  • Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application
  • Assessment may be applied under project related conditions (real or simulated) and require evidence of process
  • Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances
  • Assessment may be in conjunction with assessment of other units of competency where structural steel detailing is involved

Guidance information for assessment 

Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.
