Unit of competency details

Unit descriptor 

This unit of competency specifies the outcomes required to organise, coordinate and supervise tilt-up work on site. The knowledge and skills required to apply licensing and other regulatory requirements to the process are addressed. The erection of tilt-up pre-cast concrete panels requires the application of highly structured processes and the application of safe work practices.

Application of the unit 

This unit of competency supports the needs of site supervisors and builders with a responsibility for supervising tilt-up work on site. It complies with the National Code of Practice for Precast, Tilt-up and Concrete Elements in Building Construction

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 demonstration of the successful supervision of a tilt-up construction project.

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 

It is essential that competence is demonstrated in the relevant aspects supervising the erection of one multi point pre-cast tilt slab or one cast in situ tilt slab, each of at least 10 tonne.

Competence requires full compliance with the National Standard for Construction Work and National Code of Practice for Induction for Construction Work. Competence also needs to demonstrate a familiarity with and understanding of tilt-up construction codes of practice, standards, regulations and approval gaining processes, and their application.

A person who demonstrates competency in this unit must be able to provide evidence of the ability to:

• access and apply legislative requirements
• identify OHS hazards and assess and control OHS risks associated with the tilt-up construction process
• prepare the site OHS management plan
• plan, prepare and carry out the tilt-up construction process and implement state or territory legislative requirements and guidance material
• identify potential hazards and interpret and apply information from plans, specifications, drawings and procedures.

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 manufacturer's 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.
