CPCCCA3007 - Construct pitched roofs
(Or equivalent to be determined by unit coordinator)
Co-requisites
(Corequisite units must be studied concurrently with this unit)
Overview
This unit of competency specifies the skills and knowledge required to plan, prepare, set out and construct pitched roofs on irregular plan building shapes, meeting all relevant requirements of the National Construction Code (NCC), Australian Standards, work health and safety (WHS), and Commonwealth and state or territory legislation.
The unit includes gable, hip, hip and valley, or combinations of these in roofs that are applied to different types and styles of buildings. The roofs may have skewed, splayed or octagonal ends, may contain two separate roof pitches in the one structure, and have varying eave widths.Completion of the general construction induction training program specified by the model Code of Practice for Construction Work is required for any person who is to carry out construction work. Achievement of CPCCWHS1001Prepare to work safely in the construction industry meets this requirement.
Assessment
For Melbourne campuses
Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit’s learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.
Students will be expected to demonstrate the following required skills:
*a candidate must meet the performance criteria of this unit by constructing a roof, or a series of roofs, totalling a minimum of 30 square metres. These must include:
- a splayed end incorporating a hip end
- a splayed end incorporating a gable end
- incorporation of an octagonal end
- an intersection with another roof of a different pitch
- varying eave widths along the roof’s length.
Students will also be expected to demonstrate the following knowledge:
*compliance requirements of the National Construction Code and Australian Standards, including AS:1684 Residential timber-framed construction, relevant to constructing advanced roofs
*workplace quality policies and standards relevant to constructing advanced roofs
*safety requirements for constructing advanced roofs
*types of tools and equipment required for constructing advanced roofs
*processes for determining the following for pattern rafters:
- vertical height above birdsmouth
- length of rafters for pitch of roof
- pitch and plumb cut for rafters
*ridge boards: - abutment joints scarfed or butt jointed
- those marked for rafter positions from wall plates
*plans, specifications and drawings for constructing advanced roofs
*processes for the calculation of material requirements for constructing advanced roofs
*roof calculations for lengths, quantities and pitch for constructing advanced roofs
*roof geometry
*roof set-out
*roof types and design.
Required reading
The qualified trainer and assessor will provide teaching and learning materials as required in the form of workbooks produced by Victoria University and/or via the Victoria University e-learning system.
