This section describes the skills and knowledge required for this unit.

Required skills 

  • communication skills to liaise with internal and external personnel on technical and operational matters
  • literacy skills to interpret plans and specifications
  • numeracy skills to take measurements for construction work
  • planning and organisational skills to organise and maintain equipment
  • problem solving skills to solve logistics problems
  • safety awareness skills to:
  • apply precautions and required action to minimise, control or eliminate hazards that may exist during work activities
  • select and use required personal protective equipment conforming to industry and OHS standards
  • work systematically with required attention to detail without injury to self or others, or damage to goods or equipment
  • task management skills to work systematically with required attention to detail
  • technical skills to:
  • apply regulations and standards related to the installation of the enclosures
  • install earth mat facility and conduits
  • interpret drawings
  • lay foundations
  • use hand and power tools in civil construction work

Required knowledge 

  • civil construction:
  • construction plant, tools and equipment operation
  • enclosure construction methods
  • foundations
  • plans
  • legislation, codes of practice and other formal agreements that impact on the work activity
  • manufacturer's requirements for safe operation of equipment
  • specific OHS requirements relating to the activity and site conditions
  • typical issues and challenges that occur on site

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 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Evidence of the ability to:

  • install enclosures including pipe, pit and prefabricated manhole
  • construct in two different soil types: sand, rock, soil or combination soil types, and shore an excavation site to meet enterprise and regulatory requirements
  • use specialised hand or power tools and equipment normally used for excavation, pipe, conduit installation and site restoration safely
  • apply related OHS requirements and work practices associated with excavation, enclosure installation and site restoration.

Context of and specific resources for assessment 

Assessment must ensure:

  • sites where enclosure construction and may be conducted
  • use of construction equipment currently used in industry
  • relevant regulatory and equipment documentation that impact on construction.

Method of assessment 

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

  • review of an enclosure constructed by the candidate
  • review completed documentation including reports and records of alterations
  • direct observation of the candidate constructing an underground telecommunications infrastructure
  • oral or written questioning to assess required knowledge.

Guidance information for assessment 

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

  • ICTCBL2131A Install an above ground equipment enclosure.

Aboriginal people and other people from a non-English speaking background may have second language issues.

Access must be provided to appropriate learning and assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed.

In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.

Where applicable, physical resources should include equipment modified for people with special needs.
