Modification History

Release 1

This version first released with CPC Construction, Plumbing and Services Training Package Release 5.0.

Supersedes and is equivalent to CPCCPA3001A Prepare subgrade, base and bedding course for segmental paving. Updated to meet the Standards for Training Packages 2012.

Application

This unit specifies the skills and knowledge required to use various materials to prepare subgrade, base and bedding courses in preparation for laying segmental paving. It includes identifying soil types, determining levels and grades, calculating material and screeding and compacting base materials.

This unit applies to those who pave external areas on new and existing sites. It is suitable for people operating with some autonomy. A person working at this level would be expected to take responsibility for organising and completing tasks assigned to them without needing close supervision.

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.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Pre-requisite Unit

CPCCWHS2001 Apply WHS requirements, policies and procedures in the construction industry

Performance Evidence

To demonstrate competency in this unit, a candidate must meet the performance criteria of this unit by preparing an area of a minimum of 2.0 m x 3.0 m for segmental paving.

In doing this, the candidate must:

  • excavate the area to be paved using manual and mechanical means
  • install suitable surface and subsoil drainage
  • compact subgrade, based and bedding courses to required compaction specifications
  • screed bedding material flat and avoid any ponding.

Knowledge Evidence

To be competent in this unit, a person must demonstrate knowledge of:

  • characteristics, applications and limitations of approved paving materials:
  • various bedding materials
  • types of segmental pavers
  • waterproofing materials
  • geotextile materials
  • mortar ingredients and consistency
  • soil types
  • processes and techniques relating to paving:
  • manual and mechanical excavation
  • compacting subgrades, bases and bedding courses
  • stabilising bedding sand
  • laying of various paving patterns
  • terminology relating to paving
  • principles of California bearing ratio (CBR)
  • brick and paver expansion, and control and articulation joints
  • functional and operational features of plant, equipment and hand and power tools:
  • skid steer loader
  • backhoe
  • excavator
  • plate compactors
  • workplace safety:
  • job safety and environmental analysis (JSEA)
  • hazardous manual tasks
  • overhead and underground hazards
  • operating excavation and compacting equipment
