This unit of competency specifies the outcomes required to conduct a precision survey, including techniques for precise levelling, precise setting out and industrial measurements, and detecting structural deflection and deformation. The unit covers preparing for precision surveying by analysing project specifications and information, and identifying and controlling risks and contingencies. The unit also covers selecting and using specialised equipment, attachments and instruments necessary for precise levelling and setting out, and checking horizontal and vertical movement of structures. The unit requires the ability to apply high level surveying computations to surveying problems, including conducting statistical analysis of measurements and errors to achieve specified accuracies and tolerances. The unit supports those who work under limited supervision in a surveying team.No licensing, legislative, regulatory, or certification requirements apply to this unit of competency at the time of endorsement.
