Elements and Performance Criteria
- Prepare to perform precision survey.
- Set up precise levelling and reduce the results of a precise levelling run.
- Pertinent standards are identified, considered and adhered to according to precision surveyingproject specifications.
- Organisational documented and undocumented practices are adhered to.
- OHS requirements are planned for and adhered to.
- Constructional features of the equipment and thespecialised attachments necessary to achieve the requirements of precise levelling are determined.
- Accuracy specifications as set out in the survey precision instructions or the manufacturer specifications for tolerances relevant to precise levelling are determined.
- Precise levelling run of an accuracy consistent with the current relevant accuracy standard is carried out and results are calculated and recorded according to organisational guidelines.
- Apply specialised techniques used for precise setting out and industrial surveys.
- Applications of specialised surveying techniques used for precise setting out and optical tooling are determined.
- Applications of specialised instruments and instrument attachments used for precise setting out are determined.
- Remote measuring systems to be used in the industrial measurement are determined.
- Set out and observations using instruments and attachments suitable for precise setting out are conducted.
- Detect and monitor deflection and deformation of structures.
- Survey methods used to check horizontal movement of engineering structures and instruments used to monitor verticality of tall structures are determined.
- Survey methods used to check vertical movement due to settlement of engineering structures caused by tunnelling and mining are determined.
- Precision survey of an accuracy that will detect and monitor deformation or deflection of an engineering structure is carried out.
- Document results.
