Unit of competency details

Unit descriptor 

This unit covers the competency to prepare, select and apply cementitious products using screeding techniques to concrete sub-floors prior to the installation of flooring coverings and coatings for internal and external applications.

Application of the unit 

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.

6.3. Work area is cleaned and rubbish disposed of appropriately

6.4. Workplace documentation and/or reporting is completed

REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

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

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.

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
