Description
This unit describes the skills and knowledge required to determine pre-stressing requirements, set up equipment and follow processes for prestressing, including release of the final concrete element.The unit applies to individuals who work in accordance with pre-determined instructions and established standard operating procedures (SOPs). They work in a team, but take responsibility for their own work using discretion and judgement to monitor work processes and solve both routine and non-routine problems.The manufacture of precast concrete products is subject to various statutory and industry requirements, and the relevant legislation, industry standards and codes of practice within Australia must be applied. Requirements may vary across states and territories.
