In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
Learners who are assessed as competent against this unit standard will be able to set out, brace and erect site made, as well as prefabricated roof trusses in accordance with roof plan drawing specifications, National Building Regulations, safety legislation and within prescribed timeframes.

This competence complements the other carpentry competencies and contributes to the development of a professional community of Carpentry practitioners, who are able to use Science and Technology responsibly and cost-effectively. It should result in improved quality and service delivery in Carpentry. The contribution to The National Skills Development Strategy is the key developmental interface between learners and new competencies to be achieved.
