CPCCCA3007 - Construct pitched roofs
Nominal hours
Location
Prerequisites
(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 set out, construct and erect pitched roofs to accommodate roof coverings for weatherproofing purposes, 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 determining the required materials and process, and constructing scotch valley gable, broken hip and valley roof structures.
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 CPCCWHS1001 Prepare 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:
*setting-out, constructing and erecting:
- a skillion roof above 10 degrees for a structure of a minimum 10 square metres
- a roof, or a series of roofs, together covering a minimum of 30 square metres, including:
- a broken hip and valley
- a gable end
- a scotch valley
*setting-out: - a pattern rafter with birdsmouth, creeper reductions and eave over-hang
- roof bevels
- strutting beams and under purlins as required by span tables in AS 1684 Residential timber-framed construction and manufacturers’ specifications.
Students will also be expected to demonstrate the following knowledge:
*compliance requirements of the National Construction Code and Australian Standards relevant to constructing pitched roofs, including AS 1684 Residential timber-framed construction
*workplace quality policies and standards relevant to constructing pitched roofs
*safety requirements relevant to constructing pitched roofs
*roofing frame construction techniques
*contents of, and terms and symbols used in plans, specifications and drawings for constructing pitched roofs
*types and uses of tools and equipment used for constructing pitched roofs
*processes, relevant to constructing pitched roofs, for:
- setting out and measuring materials for frames
- calculating material requirements
*materials relevant to constructing pitched roofs
*roofing set-out procedures
*types, structural properties and uses of timber, engineered timber products and steel for constructing pitched roofs
*characteristics and construction techniques of pitched roof types: - scotch valley
- broken hip and valley
- hip and valley
- gable and verge
- skillion
- strut/props
- geometric development of bevels.
