Unit Descriptor

Unit descriptor 

This unit of competency specifies the outcomes required to establish the estimated costs associated with the acquisition of materials and labour on building and construction sites, together with the application of relevant overhead costs and margins. Knowledge of physical resource and supplier identification, assessment of the availability of and requirements for skilled labour and application of appropriate codes, regulations and approvals gaining processes is essential.

Application of the Unit

Application of the unit 

This unit of competency supports the needs of estimators, builders, managers and trade contractors within the construction industry responsible for producing estimated costs for labour, materials, overheads and on-costs on various residential and commercial construction projects within their scope of work as a trade contractor or builder.

3.5. Plant or equipment requirements are identified and costed.

4. Develop estimated project costs.

4.1. Appropriate labour rates and material costs are selected and applied.

4.2. Estimates of unit costs  are determined and applied as appropriate.

4.3. Costs to the project of WorkCover, Environmental Protection Agency (EPA) requirements, seeking approvals, waste management site fees and other statutory or additional costs are identified and applied.

4.4. Company overhead recovery and margins are applied.

4.5. Completed estimated project costs  are calculated for inclusion in a tender or bill.

Required Skills and Knowledge


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

Required skills 

Required skills for this unit are:

  • communication skills to:
  • enable clear and direct communication, using questioning to identify and confirm requirements, share information, listen and understand
  • read and interpret drawings and specifications
  • use language and concepts appropriate to cultural differences
  • use and interpret non-verbal communication
  • contractual arrangement problem solving
  • estimate labour and materials costs from written information
  • numeracy skills to calculate labour hours and costs, material quantities and costs
  • use appropriate costing software programs.

Required knowledge 

Required knowledge for this unit is:

  • how to access and interpret:
  • national codes, including Building Code of Australia (BCA) and the Plumbing Code of Australia
  • Australian standards relevant to the industry sector
  • includes state or territory and local government building and construction codes, standards and government regulations relevant to the form of building or construction being undertaken (e.g. WorkCover and EPA)
  • types of building and construction drawings and specifications
  • types, scope and usage of labour through the employee and subcontractor systems
  • operation and structure of the organisation's costing and contracting system.

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 by the preparation of a detailed estimate of labour, materials and other project costs as part of the preparation of a tender or bill for a residential or commercial construction project relevant to the specific trade or sector.

This unit of competency can 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 materials required for a project
  • gather information about material supply
  • interpret measurements and calculate quantities and costs
  • plan and allocate human resources
  • identify and cost other related costs, such as those required to meet statutory and planning approval processes
  • produce documentation that meets the timeframes and quality standards established by the organisation
  • communicate effectively, both verbally and in writing.

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:

  • documentation that should normally be available in either a building or construction office
  • relevant codes, standards and government regulations
  • office equipment, including calculators, photocopiers and telephone systems
  • computers with appropriate software to view 2-D CAD drawings, run costing programs and print copies
  • a technical reference library with current publications on measurement, design, building construction and manufacturers' product literature
  • a suitable work area appropriate to the construction process.

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.
