Apply structural principles to residential low rise constructions
|Unit Descriptor||This unit of competency specifies the outcomes required to apply structural principles to the erection or demolition of low rise residential structures using conventional methods. The unit addresses those structures classified by the Building Code of Australia (BCA) as Class 1 and Class 10. Knowledge of the application of structural principles in accordance with Australian standards is essential.|
|1 . Apply structural principles when planning the erection or demolition of a structure.||
|2 . Analyse and plan for the structural integrity of Class1 and Class 10 buildings.||
|3 . Plan, coordinate and manage the laying of footings.||
|4 . Plan, coordinate and manage the laying of floor system.||
|5 . Plan, coordinate and manage the building of structural and non-structural wall systems.||
|6 . Plan, coordinate and manage the building of roof system.||
|7 . Plan, coordinate and manage the external wall cladding of structure.||

Overview of assessment
This unit of competency could be assessed by the effective application of structural principles and concepts in accordance with the range of variables and application to only one sector of the building and construction industry.
This unit of competency can be assessed in the workplace or a close simulation of the workplace environment, provided that simulated or project-based assessment techniques fully replicate construction workplace conditions, materials, activities, responsibilities and procedures.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
A person who demonstrates competency in this unit must be able to provide evidence of the ability to:
assess the structural integrity of a variety of structures found on building and construction sites
apply the structural principles behind the safe erection and demolition of a low rise structure classified within the BCA as Class 1 and 10
apply technical construction principles to the appropriate selection, integration and building in of construction elements and components
coordinate, plan, implement and check the building of a low rise structure.
Context of and specific resources for assessment
This competency is to be assessed using standard and authorised work practices, safety requirements and environmental constraints.
Assessment of essential underpinning knowledge will usually be conducted in an off-site context.
Assessment is to comply with relevant regulatory or Australian standards' requirements.
Resource implications for assessment include:
documentation that should normally be available in either a building or construction office
relevant codes, standards and government regulations
office equipment, including calculators, photocopiers and telephone systems
computers with appropriate software to view 2-D CAD drawings, run costing programs and print copies
technical reference library with current publications on measurement, design, building construction and manufacturers' product literature
suitable work area appropriate to the construction process.
Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support.
Method of assessment
Assessment methods must:
satisfy the endorsed Assessment Guidelines of the Construction, Plumbing and Services Integrated Framework Training Package
include direct observation of tasks in real or simulated work conditions, with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application
reinforce the integration of employability skills with workplace tasks and job roles
confirm that competency is verified and able to be transferred to other circumstances and environments.
Validity and sufficiency of evidence requires that:
competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace
where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice, with a decision on competency only taken at the point when the assessor has complete confidence in the person's demonstrated ability and applied knowledge
all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence.
Assessment processes and techniques should as far as is practical take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed.
Supplementary evidence of competency may be obtained from relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff.
