Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The Evidence Guide identifies the critical aspects, knowledge and skills to be demonstrated to confirm competency for this unit. This is an integral part of the assessment of competency and should be read in conjunction with the Performance Criteria and Range Statement.

What critical aspects of evidence are required to demonstrate competency in this unit?

Compliance with occupational health and safety regulations applicable to workplace operations.

Application of organisational management policies and procedures including quality assurance requirements where appropriate.

Assessment of timber framed designs, evaluation of plans and specifications and identification of faults. The selection of structural members for roofs, ceilings, walls, floors and stumps relating to performance and the associated reporting of data, findings, recommendations and rectification strategies for at least one (1) building project of up to two (2) storeys or equivalent in compliance with relevant legislation.

Provision of reports to appropriate body/individual as determined by the project brief.

Application of strategic plans, workplace policies and procedures.

Are there any other units which should be assessed with this unit or which relate directly to this unit?

This unit should be co-assessed with BCG5006, BCG5001 and BCG5039.

Holistic assessment should be applied where appropriate to form a complete work function.

What specific knowledge is required to achieve the performance criteria?

Processes for the interpretation of reports, working drawings and specifications.

Some of these are covered by the national key competencies, although others may be added. The questions below highlight how these processes are applied in this competency unit. The number in brackets indicates the level to which the key competency needs to be demonstrated where (1) working within set conditions and processes, (2) management or facilitation of conditions or processes are exercised, and (3) design and/or development of conditions or process are required.

How will the candidate apply the following key competency in this unit?

The candidate will need to:

Collect, analyse and organise information

Research, analyse, organise and understand the process for assessing timber-framed designs on buildings up to two (2) storeys plus subsequent reporting procedures. Level 2

Work with others and in a team

Work with others and in a team by recognising dependencies and using co-operative approaches to optimise satisfaction and productivity. Level 1

Solve problems

Establish analytical processes, including diagnostic processes, which anticipate and allow for risks, cater for both direct and indirect evidence, avoid or minimise reworking and avoid wastage. Level 3

Use mathematical ideas and techniques

In what context should assessment occur?

Competency is demonstrated by performance of all stated criteria, including paying particular attention to the critical aspects and the knowledge and skills elaborated in the Evidence Guide and within the scope defined by the Range Statement.

Assessment must take account of the endorsed assessment guidelines in the Construction Training Package.

What methods of assessment should apply?

Assessment of this competency is most likely to be project related under real or simulated conditions and require portfolios or other forms of indirect evidence of process. Direct evidence may include certification of compliance on the final outcome or authorisation for commencement by a competent authority.

Assessment must confirm the inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.

Assessment should reinforce the integration of the key competencies.

What are the specific resource requirements for this unit?

A situation, real or realistically simulated, requiring assessment of timber framed designs for one and two storey buildings.

The learner and trainer should have access to appropriate documentation and resources normally used in the workplace.
