Competency is to be demonstrated by the effective calculation of measurements and calculations of materials in accordance with the range listed in the range of variables statement, relevant to the work orientation.
(1) Critical Aspects of Evidence
It is essential that competence is observed in the following aspects:
communicate effectively to enable accurate calculations and measurements
demonstrate effective use of measuring devices
accurate measurements taken and recorded
perform simple calculations to specifications
estimate quantities and costs to requirements
(2) Pre-requisite Relationship of Units
Nil
(3) Underpinning Knowledge and Skills
Knowledge
A knowledge of:
drawings and specifications
materials relevant to the construction process
basic operations in simple geometry, measurement and calculations
costing relative to the construction process
Skills
The ability to:
read and interpret drawings
measure and calculate manually
record measurements
operate electronic calculating devices
communicate effectively
(4) Resource Implications
The following resources should be made available:
information on construction materials appropriate to the relevant construction process
suitable work area appropriate to the activity
suitable site plans/drawings and/or specifications
measuring and calculating devices
(5) Method of Assessment
Competency shall be assessed while work is undertaken under direct supervision with regular checks, but may include some autonomy when working as part of a team.
Competency in this unit may be determined concurrently, based upon integrated project work.
Assessment may be intermittent checking at the various stages of the job application in accordance with the performance criteria, or may be at the completion of each process.
(6) Context of Assessment
Competency shall be assessed in the workplace or simulated workplace environment in accordance with work practices and safety procedures.
