Unit Of competency

Modification History

Release 1

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

New unit.

Application

This unit of competency specifies the skills and knowledge required to plan and carryout the demolition of stressed and pre-cast structures in accordance with specifications.

It includes planning and preparation for the work, inspecting bars, components and defining the work area.

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 unit CPCCWHS1001 Prepare to work safely in the construction industry meets this requirement.

Licensing, legislative, regulatory or certification requirements apply to demolition work in different states and territories. Candidates are advised to consult with the relevant regulatory authorities.

Pre-requisite Unit

CPCCWHS2001

Apply WHS requirements, policies and procedures in the construction industry

Unit Sector

Demolition.

3.4

Conduct visual inspection to confirm loads and deviations from original plans and specifications, under the direct supervision of a structural engineer.

4

Examine pre-cast elements.

4.1

Review structural engineer’s assessment of the structure, including connections to slabs or beams, for the preparation of a demolition work plan.

4.2

Confirm how pre-cast elements are connected to the main building structure and the methods that were used to install them.

5

Demolish structure.

5.1

Conduct visual inspection to confirm loads and connections from original plans and specifications, under the direct supervision of a structural engineer and communicate with demolition team.

5.2

Erect public protection outside buildings above one story in height, as required.

5.3

Cut or break out sections of concrete panel to substantiate how the connections to the structure were made.

5.4

Prepare the work area for removal of panels.

5.5

Assessment requirements

Modification History

Release 1

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

New unit.

Performance Evidence

To demonstrate competency in this unit the candidate must demolish one stressed panel structure and one pre-cast panel structure.

After identifying and controlling hazards, the candidate, working as a part of a team, must demolish one stressed panel structure of not less than four metres high, not less than three metres wide and not less than two tonnes in weight and one pre-cast panel structure of not less than four metres high, not less than three metres wide and not less than two tonnes in weight.

In doing this, the candidate must meet the performance criteria for this unit.

Knowledge Evidence

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

  • the compliance requirements of the relevant Australian Standards, Building Code of Australia (BCA), model codes of practice, environmental and work health and safety (WHS) legislation
  • basic theory related to cable stressing as a reinforcement technology
  • calibration procedures related to stressing techniques and equipment
  • construction and steelfixing tensioning terminology
  • factors affecting concrete bonding, curing and strength
  • grouting equipment and procedures
  • job safety analysis (JSA)
  • safe work method statements (SWMS)
  • safety data sheets (SDS)
  • materials storage and environmentally friendly waste management
  • plans, drawings and specifications
