Elements and Performance Criteria

1. Plan and prepare work
   • Plans and specifications are interpreted and clarified with the supervisor.
   • The quantity and quality of materials are checked to ensure they conform to design drawings and specifications.
   • Tools and equipment are selected and checked for serviceability according to enterprise guidelines.
   • Occupational Health and Safety (OHS) hazards are identified, risks assessed and controls implemented.
   • Environmental implications of constructing concrete structures are identified and reported to the supervisor.
2. Set out and prepare the site
   • Services are determined and located from site plans.
   • The position of the structure or feature is marked out according to design drawings and specifications.
   • Profiles are established to conform to the tolerances nominated within the design drawings and specifications.
   • Subsoil is prepared by removing all debris, vegetable matter and topsoil to provide a solid foundation for concrete.
   • Drainage systems are installed according to design drawings and specifications.
   • Form work is installed to the site in a manner that will ensure it remains rigid during concrete pouring operations.
   • Sub-base material is placed and compacted to the required finished levels.
   • Preparation of the site is completed according to the type of structure or feature to be constructed.
3. Mix and pour concrete
   • Proportions for concrete mix are determined according to the strength requirements of the project.
   • Volume of dry materials necessary to produce final concrete mix is determined.
   • All dry ingredients and required additives are mixed together to ensure a thorough blending of all materials is achieved.
   • Sufficient water is introduced to produce a concrete mix to the required consistency.
   • Concrete mix samples are taken for testing, if required, to check for conformity to specifications.
   • Concrete is poured to designated levels in a manner to avoid segregation of materials.
   • Concrete is consolidated using an approved vibration method to industry standard (AS3600) to ensure air pockets are eliminated.
4. Finish concrete
   • Concrete is screeded to a flat surface to maintain the desired finished level.
   • Surface is trowelled according to design drawings and specifications.
   • A Concrete is finished off according to design drawings and specifications.
5. Check quality of work and clean up site
   • Quality of finished works is inspected to ensure the standard of the finished structure or feature is in accordance with design drawings and specifications.
   • Form work is removed and cleaned in a manner which will allow for re-use of the form work.
   • All debris is removed and disposed of in a manner that minimises risk to the environment.
   • All tools and equipment are cleaned and stored according to enterprise guidelines.

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 workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following interpret site plans and specifications set out and prepare a site for receival of concrete pour set and finish concrete check quality of work and clean up site
Context of and specific resources for assessment	Competency requires the application of work practices under work conditions Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances
