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

This unit of competency could be assessed by undertaking a range of tasks 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

A person should demonstrate the ability to:

complete planning, preparation, reinforcement placement and installation of block out; install cast-in fittings; and sequence, place, finish and cure concrete, minimising cold joint and undertaking compaction of concrete for one slip or jump form to engineer’s specifications

locate, interpret and apply relevant information, standards and specifications relating to conducting off-form vertical concrete operations

comply with site safety plans and procedures

comply with organisational policies and procedures relating to conducting off-form vertical concrete operations while maintaining quality requirements outlined in job specifications

safely and effectively operate and use plant, tools and equipment required to conduct off-form vertical concrete operations

communicate and work effectively and safely with others during each stage of the work task.

Context of and specific resources for assessment

Assessment of this unit:

must be in the context of the work environment

may be conducted in an off-site context, 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
