This includes the ability to carry out the following as required to assist grouting or cementing operations: apply legislative, organisation and site requirements and procedures operate cleaning equipment apply communication procedures use mixing equipment measure tank dimensions and calculate volumes record casing lengths and quantities accurately |
Required knowledge |
Specific knowledge is required to achieve the Performance Criteria of this unit, particularly its application in a variety of circumstances in which the unit may be used. This includes knowledge of the following, as required to assist grouting or cementing operations: site and equipment safety requirements possible effects of grout, cement or cement additives on health environmental requirements and procedures team roles and objectives during the grouting or cementing operations properties of grout, cement or cement additives safe work procedure for the grouting or cementing process |
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 assisting with grouting or cementing operations implementation of requirements, procedures and techniques for the safe, effective and efficient completion of assisting with grouting or cementing operations working with others to undertake and complete grouting or cementing operations that meet all of the required outcomes consistent timely completion of assisting with grouting or cementing operations that safely, effectively and efficiently meets the required outcomes |
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. 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 the work 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 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 consistently achieving the required outcomes first hand testimonial evidence of the candidate's: working with others to undertake and complete grouting or cementing operations |
Guidance information for assessment | Consult the SkillsDMC User Guide for further information on assessment including access and equity issues. |
