Elements and Performance Criteria

1. Prepare for open pit mine survey.
   • Open pit mine surveying objectives and specifications are identified in consultation with appropriate persons.
   • Processes and procedures involved in exploring mineral deposits are planned according to organisational requirements.
   • Required mining methods are detailed according to project specifications and organisational requirements.
2. Plan open pit mine survey.
   • Surveying objectives, deliverables, constraints, work activities and surveying resource and equipment needs are identified and documented according to spatial data specifications and organisational requirements.
   • Project management mechanisms are implemented to schedule, measure, record and report progress of activities in relation to agreed schedule and plans.
   • Agreed communication processes between client and other appropriate persons are implemented and maintained.
   • Risk management and contingency strategies are followed to ensure project complies with legal and statutory standards and organisational requirements.
3. Carry out open pit mine surveying tasks.
   • Identified spatial components of open pit mine are accurately measured or set out according to project specifications.
   • Measured spatial data is reduced to project reference system for comparison with design.
   • Mine drawings are created to meet project specifications.
   • Captured data is used to calculate mine volumes according to project specifications.
   • Measurements are validated and recorded according to organisational requirements.
   • Problems are identified and resolved, and contingencies managed according to organisational requirements.
4. Finalise and report open pit mine survey outcomes.
   • Project is finalised and checked for compliance with project specifications and organisational requirements.
   • Appropriate persons are notified of project results according to organisational requirements.
   • Documentation is completed and spatial data archived according to project and organisational requirements.
