Required knowledge includes: the procedures for collaborating with the client and other staff in the selection of the preferred option significance of graphical representations of designs in terms of procedural requirements, design objectives and client or contractual requirements relevant manufacturing and operational requirements, safety and related standards the functional operation of the component/assembly to be drawn surfaces that are to be in contact or separated the appropriate type of fit for contacting surfaces, and reasons for selecting the chosen type of fit the effect of surface finish on the performance/operation of surfaces appropriate datum points procedures for determining tolerances design functional specification choice of components, materials, methods and processes in terms of the range of options available and the manner in which the design specification is satisfied options for graphical methods of representation scientific principles and mathematical techniques underpinning design element choices and decisions required graphical representation procedures for the preparation of production drawings, specifications and operating and maintenance instructions/manuals clients and other people affected by the design organisational procedures and required communication techniques organisational requirements for the preparation of production drawings, specifications and operating and maintenance instructions/manuals for products and systems persons to be consulted and procedures for verifying and implementing production graphics, technical specifications and operational and maintenance instructions/manuals worksite procedures for acting on implementation, installation and commissioning feedback worksite procedures for the processing and filing of production graphics, specifications and operating and maintenance instructions/manuals file storage and archiving procedures Required skills include: using appropriate communication skills for contacting and confirming specifications with the client discussing the alternative options and their relative strengths and weaknesses with the client and selecting the most acceptable option chosen applying graphical techniques correctly addressing design specifications, manufacturing and operational requirements, safety and related standards appropriately in the initial graphical representations presenting graphical representations the dimensions, limits and fits, tolerances and surface textures, datum references and geometry tolerances as determined by design calculations and in accordance with engineering references, standards and codes producing initial graphical representation and documentation materials, manufacturing methods and processes and design functional specifications sufficient for client, design team and interested party consultation and validation producing initial graphical representation/s to organisational requirements using suitable graphical techniques producing initial production graphics, technical specifications and operational and maintenance instructions/manuals in accordance with worksite procedures and client needs using appropriate communication skills in confirming that the design graphical representation meets the needs of the client and the expectations of other team members and interested parties completing organisational procedures and sign-off documentation preparing production graphics, specifications and instructions in accordance with the agreed design concept and organisational requirements and incorporating feedback on initial design graphics contacting the client, design team and other affected persons and the production graphics, technical specifications and verifying operational and maintenance instructions/manuals prior to implementation incorporating feedback from the implementation, installation and commissioning phases into final graphics and specifications processing, filing and saving all graphics, specifications, instructions and related documentation in correct format and location in accordance with worksite procedures |
