Required Skills
This describes the essential skills and knowledge and their level required for this unit. |
Required skills |
Technical skills sufficient to safely detail and design timber structures which meet required standards and budgetary constraints and to produce design drawings suitable for use on constructions sites Communication skills and interpersonal techniques sufficient to interact appropriately with colleagues and others in the workplace Literacy skills sufficient to accurately complete, record and maintain information Numeracy skills sufficient to select appropriate mathematical processes to calculate design dimensions and measure lengths and spans Problem solving skills sufficient to identify problems and demonstrate appropriate response procedures |
Required knowledge |
Applicable Commonwealth, State or Territory legislation, regulations, standards, codes of practice and established safe practices relevant to the full range of processes for designing timber structures Organisational and site standards, requirements, policies and procedures Environmental protection requirements, including the safe disposal of waste material Quantitative relationship between component loads, supports and gains, and species, type, dimensions and grade Common industry terminology for all component types and timber cuts, all structure types and construction methods Industry standard cross-section sizes and profiles, length and spacing dimensions Established communication channels and protocols Problem identification and resolution strategies and common fault finding techniques Types of tools and equipment relevant to designing timber structures and procedures for their use, operation and maintenance Appropriate mathematical procedures for estimating and measuring, including calculating time to complete tasks Procedures for recording and reporting workplace information |
Evidence Required
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. | |
Overview of assessment | A person who demonstrates competency in this unit must be able to provide evidence that they can accurately interpret plans to develop and design timber structures in line with industry and organisational requirements |
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 and satisfy all of the requirements of the elements of this unit and include demonstration of: following applicable Commonwealth, State or Territory legislative and regulatory requirements and codes of practice relevant to designing timber structures following organisational policies and procedures relevant to designing timber structures communication techniques and safe work practices in the work area interpreting drawings and loading conditions interpreting and applying technical information and conveying information in written, sketch and oral form applying mathematical procedures such as estimation and measurement developing and selecting truss and/or frame and/or floor layout options and detailing framing design providing design and production advice |
Context of and specific resources for assessment | Competency is to be assessed in the workplace or realistically simulated workplace Assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints Assessment of required knowledge, other than confirmatory questions, will usually be conducted in an off-site context Assessment is to comply with relevant regulatory or Australian Standards requirements The following resources should be made available: workplace location or simulated workplace materials and equipment relevant to undertaking work applicable to this unit specifications and work instructions |
Method of assessment | Assessment must satisfy the endorsed Assessment Guidelines of the FPI11 Training Package Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of required knowledge Assessment must be by direct observation of tasks, with questioning on required knowledge and it must also reinforce the integration of employability skills Assessment methods must confirm the ability to access and correctly interpret and apply the required knowledge Assessment may be applied under project-related conditions (real or simulated) and require evidence of process Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances Assessment may be in conjunction with assessment of other units of competency The assessment environment should not disadvantage the candidate Assessment practices should take into account any relevant language or cultural issues related to Aboriginality, gender or language backgrounds other than English Where the participant has a disability, reasonable adjustment may be applied during assessment Language and literacy demands of the assessment task should not be higher than those of the work role |
