Description
This unit of competency specifies the skills and knowledge required to carry out levelling operations to establish correct and accurate set-out of buildings and components, meeting all relevant requirements of the National Construction Code (NCC), Australian Standards, work health and safety (WHS), and Commonwealth and state or territory legislation. It includes: using the rise and fall and height of collimation methodssetting up, testing and using levelling devicesundertaking closed and open traverses using a range of levelling equipment calculating distances using stadia lines.Completion of the general construction induction training program specified by the model Code of Practice for Construction Work is required for any person who is to carry out construction work. Achievement of CPCWHS1001Prepare to work safely in the construction industry meets this requirement.No licensing, legislative or certification requirements apply to this unit at the time of publication.
