Elements and Performance Criteria
- Select software
- Applicable Occupational Health and Safety (OHS), environmental, legislative and organisational requirements relevant to drawing and detailing trusses and/or frames and/or floors using computerised systems are identified and followed
- Software options are reviewed and evaluated against specified workrequirements
- Appropriate software program is selected appropriate to work requirements
- Interpret plans and loading conditions
- Plans and work order documentation are obtained and interpreted
- Plans are interpreted and work requirements specified, assessed and referred to engineers for calculations
- Additional information and data required to estimate assemblies is obtained from appropriatepersonnel or other sources
- Functional and pictorial images of structures, trusses and/or frames and/or floors are created
- Design requirements outside software limitations are identified and referred to appropriate personnel
- Communication with others is established and maintained in line with OHS and organisational requirements
- Use computer programs to estimate trusses and/or frames and/or floors
- Fixed design details are transferred to layout data in line with software requirements
- Truss and/or frame and/or floor types are identified and timber type and species selected in line with material suitability and availability
- Design structure is defined by common industry spacing of trusses or frames or floors and their components in line with industry standards
- Component sizes are fixed to clarify and firm design options
- Layouts, spacing and sizing of individual structural members are progressively selected in line with software requirements
- Design details are produced in line with software and work order requirements
- Design options are selected on the basis of feasibility, ease of erection, cost, material availability, customer preference and site standards
- Design details are reviewed and revised in line with site and customer standards without compromising truss, frame or structure strength
- Prepare quotation
- Estimations are calculated and quotation is produced in the designated format using recommended software and computer program
- Quotation is reviewed and checked for completeness and accuracy in line with organisational requirements
- Modifications are made to computer design to meet work order requirements, if required
- Computer records are completed and quotation is prepared for presentation in line with workplace procedures
