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:

prepare the surfaces of at least four existing concrete slabs each measuring at least 10 square metres; two slabs must be prepared for bonded topping slabs and two for unbonded topping slabs

install bonded and unbonded topping slabs to prepared surfaces

cure and finish the topping slabs to specifications

locate, interpret and apply relevant information, standards and specifications relating to installing topping slabs

comply with site safety plans and procedures

comply with organisational policies and procedures relating to installing topping slabs while maintaining quality requirements outlined in job requirements

safely and effectively operate and use plant, tools and equipment required to install topping slabs

communicate and work effectively and safely with others.

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

must meet relevant compliance requirements.

Resource implications for assessment include:

an induction procedure

realistic tasks or simulated tasks covering the mandatory task requirements

relevant specifications and work instructions

tools and equipment appropriate to applying safe work practices

support materials appropriate to activity

workplace instructions relating to safe work practices and addressing hazards and emergencies

safety data sheets.

Method of assessment

Assessment for this unit must verify the practical application of the required skills and knowledge, using a combination of the following methods:

direct observation of tasks in real or simulated work conditions

questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application

review of relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff.

Guidance information for assessment

This unit could be assessed on its own or in combination with other units relevant to the job function.

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.

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.

Required skills

learning skills to:

evaluate own actions and make judgments about performance and necessary improvements

respond to change, such as differences in work site, and environmental and quality requirements

numeracy skills to:

calculate and apply correct timings required for curing and sealing

calculate and confirm correct quantities of materials for work tasks

oral communication skills to:

enable clear and direct communication, using questioning to identify and confirm requirements, and share information

report work site hazards to appropriate personnel, including faults in tools, equipment or materials

use language and concepts appropriate to cultural differences

reading skills to:

interpret documentation, including drawings and specifications

interpret manufacturer instructions for safely handling tools, equipment and materials

understand written instructions, procedures and signage

writing skills to complete pre-operational checklists and simple equipment fault forms

Required knowledge

application and use of control joints

concrete resurfacing materials and techniques, including:

curing duration and effect on ultimate strength

role of abrasive blasting when installing bonded topping slabs

general construction terminology

mortar mix composition and additives relevant to topping slabs

processes for calculating material requirements

properties of concrete to be able to minimise waste, delay and faults in installing topping slabs

quality requirements of the task, including:

internal organisational quality policy and standards

manufacturer specifications

workplace operations and procedures

processes for material storage and environmentally friendly waste management

types and applications of concrete materials used when installing topping slabs

types, characteristics, uses and limitations of plant, tools and equipment relevant to installing topping slabs and resurfacing existing concrete

types, location and use of relevant safety resources and information such as:

job safety analyses (JSA) and safe work method statements (SWMS)

safety data sheets (SDS)

signage and barricades

workplace and equipment safety requirements, including procedures for identifying, recording and rectifying equipment faults
