Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following:

mark out the site for the structure according to design drawings and specifications

establish the levels and prepare footings where required

use a wide range of power tools efficiently and safely

fix, join or assemble timbers using a variety of recognised methods

apply a variety of surface finishes

ensure the completed structure or feature meets the quality standard in the specifications.

Context of and specific resources for assessment

Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.
