Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit
The evidence required to demonstrate competency in this unit must be relevant to worksite operations and satisfy all of the requirements of the performance criteria, required skills and knowledge and the range statement of this unit and include evidence of the following:
knowledge of the requirements, procedures and instructions for the preparation of civil works cost estimates
implementation of procedures and techniques for the safe, effective and efficient preparation of civil works cost estimates
the identification of the relevant information and scope of the work required to meet the required outcomes
the identification of viable options and the selection of civil works cost estimates that best meet the required outcomes
working with others to undertake and complete the preparation of civil works cost estimates
consistent successful preparation of civil works cost estimates
Context of and specific resources for assessment
This unit must be assessed in the context of the work environment. Where personal safety or environmental damage are limiting factors, assessment may occur in a simulated environment provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills.
Evidence for assessment is best gathered using the outcomes of products and processes of the workplace.
The assessment environment should not disadvantage the participant. For example, language, literacy and numeracy demands of assessment should not be greater than those required on the job.
Customisation of assessment and delivery environment to sensitively accommodate cultural diversity.
Aboriginal people and other people from a non English speaking background may have second language issues.
Assessment of this competency requires typical resources normally used in a civil works environment. Selection and use of resources for particular worksites may differ due to site circumstances.
Where applicable, physical resources should include equipment modified for people with disabilities.
Access must be provided to appropriate learning and/or assessment support when required.
Method of assessment
This unit may be assessed in a holistic way with other units of competency. The assessment strategy for this unit must verify required knowledge and skill and practical application using more than one of the following assessment methods:
written and/or oral assessment of the candidate's required knowledge to apply in undertaking of the preparation of civil works cost estimates
observed, documented and/or first hand testimonial evidence of the candidate's:
implementation of appropriate procedures and techniques for the safe, effective and efficient achievement of the required outcomes
identification of the relevant information and scope of the work required to meet the required outcomes
identification of viable options and the selection of civil works cost estimates that best meet the required outcomes
consistently achieving the required outcomes
first hand testimonial and documentary evidence of the candidate's:
working with others to undertake and complete the preparation of civil works cost estimates
provision of clear and timely required support and advice on the preparation of civil works cost estimates
Guidance information for assessment
Consult the SkillsDMC User Guide for further information on assessment including access and equity issues.
