Elements and Performance Criteria

1. Prepare drawing environment.
   • Project specifications are sourced and analysed; and objectives, deliverables, constraints and principal work activities are identified and documented in consultation with appropriate persons.
   • Hardware and software are set up and used according to organisational requirements.
   • Menus and drawing defaults are customised to suit project specifications according to organisational requirements.
   • Survey database is created according to organisational requirements.
2. Create mine drawings.
   • Drawings for surface mine are created using available software drawing functions and features to meet project specifications.
   • Drawings are designed to incorporate mines safety requirements according to project specifications and organisational requirements.
   • Drawing entities are linked to database attributes to suit project specifications.
   • Supplementary data is extracted from existing mining and engineering plans and drawings to meet project specifications.
   • Detailed views are created using various scales to meet project specifications.
   • Plots are produced at required scale to meet project specifications.
3. Produce output.
   • Files are saved in various formats according to organisational requirements.
   • Entities are produced from drawing files or database and listed in required format to meet project specifications.
   • Identified spatial components are accurately measured or set out, and data is reduced to project reference system.
   • Mine volumes are calculated and validated using captured data and measurements, and errors are resolved or contingencies managed according to specifications and organisational requirements.
4. Finalise drawings.
   • Drawings are finalised and checked for compliance with project specifications and organisational requirements.
   • Appropriate persons are notified of results according to organisational requirements.
   • Documentation is completed and spatial data archived according to organisational requirements.
