Elements and Performance Criteria

1. Interpret plans and loading conditions
   • Interpret and assess plans, drawing views and notes; identify loading information, design requirements and restrictions.
   • Obtain additional information and data from appropriate personnel or sources.
   • Create functional and pictorial image of structure, trusses or frames based on design requirements.
   • Refer design requirements outside software limitations to appropriate personnel for resolution.
2. Test and select design options
   • Transfer fixed design details to layout data in line with software requirements.
   • Specify frame or truss design types, and select timber type and species in line with material suitability and availability.
   • Set common industry spacing of frames, trusses and their components to defined design structure in line with industry standards.
   • Fix component sizes to clarify and firm design options.
   • Select layouts, spacing and sizing of individual structural members progressively in line with software requirements.
   • Select, review and revise design details in line with work order.
3. Produce layouts and cutting requirements
   • Review design records for design integrity, completeness and consistency in line with certifying authority standards.
   • Produce structure layout drawings and truss or frame assembly drawings using appropriate software.
   • Produce component cutting detail in line with production requirements and schedules.
   • Prepare and document production and installation advice in line with organisational procedures and industry standards.
   • Complete and maintain design records and documentation in line with organisational procedures.
4. Provide advice on design and production issues
   • Answer questions about designs and assembly requirements clearly and comprehensively.
   • Use effective communication techniques to assist and develop production personnel.
   • Provide alternative materials and sizes for components within design scope and production requirements.
   • Discuss common site problems and select appropriate prevention strategies to ensure future practice meets design requirements.
