This unit supports the attainment of skills and knowledge required for competent workplace performance in the wide variety of flooring technology operations. The competency applies to an on site environment and involves application of skills and knowledge at a trade worker level. These skills and knowledge are to be used within the scope of the individual's job and authority.

6.4. Workplace documentation and/or reporting is completed

Required skills

collect, organise and understand information related to work orders, basic plans and safety procedures

communicate ideas and information to enable confirmation of work requirements and specifications, coordination of work with site supervisor, other workers and customers, and the reporting of work outcomes and problems

work with others and in a team by recognising dependencies and using cooperative approaches to optimise work flow and productivity

use pre-checking and inspection techniques to anticipate concrete sub-floor preparation problems to avoid re-work and wastage

recognise and respond to circumstances outside instructions or personal competence

plan and organise activities including the preparation and layout of the worksite and the obtaining of equipment and materials to avoid any back tracking, work flow interruptions or wastage

use mathematical ideas and techniques to correctly complete measurements, calculate area and estimate other material requirements

clarify and confirm work instructions

plan work within given task parameters

accept responsibility for given tasks

set, monitor and satisfy personal work goals

satisfy the competency requirements for the job

maintain current knowledge of:

tools and materials

installation techniques

seek learning opportunities

use the limited workplace technology related to the preparation of a concrete sub-floor including tools, equipment, calculators and measuring devices.

Required knowledge

State or Territory OHS legislation, regulations, standards and codes of practice relevant to levelling sub-floors

organisational and site standards, requirements, policies and procedures for levelling sub-floors

environmental protection requirements

established communication channels and protocols

problem identification and resolution

types of tools and equipment and procedures for their safe use, operation and maintenance

characteristics of materials, products and defects

set up and operation of equipment

procedures for the recording, reporting and maintenance of workplace records and information

appropriate mathematical procedures for estimation and measurement

characteristics and requirements of concrete sub-floor preparation

type, characteristics, uses and limitations of levelling compounds and primers

workplace safety system requirements related to the application of levelling compounds and primers

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.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Interpret work order and locate relevant information

Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment

Follow work instructions, operating procedures and inspection practices to:

prevent damage to goods, equipment and products

maintain required production output and product quality

minimise the risk of injury to self and others

Complete to Australian Standards a minimum of two sub-floor preparations which are to include:

a patch and repair

a level pour

Work effectively with others

Modify activities to cater for variations in workplace context and environment

Context of, and specific resources for assessment

The application of competency is to be assessed in the workplace or realistically simulated workplace

Assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints

Assessment of essential underpinning knowledge, other than confirmatory questions, will usually be conducted in an off-site context

Assessment is to comply with relevant regulatory or Australian Standards requirements

The following resources should be made available:

workplace location or simulated workplace

materials and equipment relevant to sub-floor levelling activities

specifications and work instructions

Method of assessment

Assessment must satisfy the endorsed assessment guidelines of the Furnishing Industry Training Package

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge

Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application

Assessment may be applied under project related conditions (real or simulated) and require evidence of process

Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances

Assessment may be in conjunction with assessment of other related units of competency

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.
