Erect trestle and plank system.


Trestle and plank system is selected to meet the Australian standard AS6001-1999 and work requirements.


Trestle system components are collected and located at work site.


Trestles and planks are inspected for serviceability as determined by the Australian standards.


Trestles are appropriately positioned for the work and the planks to be used.


Planks are fitted to the trestles at the required height using authorised procedures and within work site or regulatory restrictions.


Inspect system.


Trestle and plank work platform is inspected before and during use.


Faults found are reported to supervisor and rectifications are conducted or system is labelled to prevent use pending repair.

  • identifying the purpose of tags and logs of use for equipment
  • job safety analysis (JSA) and safe work method statements
  • manufacturer and supplier instructions for plant and equipment
  • names and functions of equipment, components and materials
  • requirements to plan own work
  • safely use equipment, shift and handle products and materials.

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

This unit of competency could 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:

  • identify situations where the use of trestle and plank system is appropriate
  • explain benefits of one trestle and plank system compared to another
  • select and use appropriate trestles, planks and work methods
  • operate from basic instruction without constant supervision
  • identify faults in trestles and planks
  • execute work within agreed timeframes and standards
  • interpret manufacturers' documentation
  • apply knowledge of industry products to identify:
  • trestle and plank systems that meet the Australian standard
  • common faults in trestle and plank systems and problems that require reporting
  • follow work instructions, operating procedures and inspection practices to:
  • prevent damage to goods, equipment or products
  • work effectively alone or with others and minimise the risk of injury
  • modify work activities to cater for variations in work site procedures, contexts and environment
  • identify and use appropriate behaviour for interactions with other workers, supervisors, clients and members of the public
  • maintain workplace records in relation to materials, plant and equipment use
  • use safe handling requirements, based on information provided for equipment, products and materials.

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:

  • work site
  • trestles
  • planks.

Assessment of this unit of competency may be in conjunction with assessment of other units commonly performed at the same time in normal job roles.

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 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.

Guidance information for assessment 

This unit could be assessed on its own or in combination with other units relevant to the job function, for example:

  • CPCCCM2010A Work safely at heights.

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.

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.
