This includes knowledge of the following, as required to conduct bitumen sprayer operations: site and equipment safety requirements bitumen spraying procedures bituminous materials and their characteristics processes for heating bitumen equipment types, characteristics, technical capabilities and limitations operational, maintenance and basic diagnostic procedures site isolation and traffic control responsibilities and authorities processes for the calculation of material requirements, application rates and travel speed materials safety data sheets and materials handling methods project quality requirements civil construction terminology safe operating techniques in all terrain JSAs/safe work method statements |
Evidence Required
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 | 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 conducting bitumen sprayer operations implementation of requirements, procedures and techniques for the safe, effective and efficient completion of bitumen sprayer operations working with others to undertake and complete bitumen sprayer operations that meets all of the required outcomes consistent timely completion of bitumen sprayer operations that safely, effectively and efficiently meets the required outcomes a minimum of three different materials to be loaded, mixed, heated and sprayed for two sprayer loads each to be used for two straight runs, two tapers or turning slots and two restricted areas to specified tolerances (spray runs to be a minimum total of 60% of the tank) a minimum of two areas to be hand lanced, each with a different material and to the specified tolerance completion of all calculations and spray sheets for the activities in the two previous dot points |
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. Assessment of this competency requires typical resources normally used in a resources and infrastructure sector environment. Selection and use of resources for particular worksites may differ due to the site circumstances. 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. 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 observed, documented and/or first hand testimonial evidence of the candidate's: implementation of appropriate requirement, procedures and techniques for the safe, effective and efficient achievement of required outcomes consistent achievement of required outcomes first hand testimonial evidence of the candidate's: working with others to undertake and complete bitumen sprayer operations |
Guidance information for assessment | Consult the SkillsDMC User Guide for further information on assessment including access and equity issues. |
