The unit covers project managing surveying activities, including planning collection methodologies and allocating resources and work tasks in a team environment. The unit also covers analysing existing survey control data and networks to identify non-conformities and the need for additional controls, and implementing a network of points for controlling horizontal and vertical positions. The unit requires the ability to program, calibrate and operate GNSS equipment, relate surveying data to a reference system, and identify and resolve discrepancies with the reference system. The unit supports those who work in a technical management role in a surveying team.No licensing, legislative, regulatory, or certification requirements apply to this unit of competency at the time of endorsement.
