Elements and Performance Criteria

1. Prepare for work
   • Applicable work health and safety (WHS), legislative and organisational requirements relevant to installing impact and sound absorbing underlay are verified and complied with
   • Instructions and/or plans are read and interpreted to identify process required to complete work tasks
   • Sub-floor condition is assessed for suitability for installation of impact and sound absorption underlay for timber flooring installation
   • Suitable adhesives, trims and accessories are selected if required
   • Impact and sound absorption underlay is checked against work orders
   • Tools, equipment and materials are selected and checked prior to use to ensure that they are appropriate for the work, serviceable and in a safe condition
   • Sequence of work is planned, including the starting point, to ensure cutting, laying and fitting is in logical order
2. Set out materials
   • Impact and sound absorption underlay to be installed is checked against the order
   • Impact and sound absorption underlay are acclimatised according to manufacturer recommendations
   • Impact and sound absorption underlay for fixing are organised and used in accordance with relevant safety management requirements
   • Working lines and starting point are established
3. Cut impact and sound absorption underlay
   • Instructions and sequence for laying and fixing are followed
   • Impact and sound absorption underlay is laid out to meet directional sequence, specification requirements and to minimise waste and joins as appropriate
   • Impact and sound absorption underlay is cut to required shape with minimum waste of materials
4. Lay impact and sound absorption underlay
   • Materials for fixing are organised and used in accordance with relevant safety management requirements
   • Adhesives and edge strips/accessories are prepared for use as required
   • Adhesive is applied to sub-floor, if required
   • Impact and sound absorption underlay is fixed using methods and equipment which follow manufacturer instructions
   • Completed installation is checked for flaws in installation and materials and faults rectified following workplace procedures
5. Complete housekeeping
   • Unused materials are stored or recycled as required
   • Tools and equipment are cleaned and stored appropriately
   • Work area is cleaned and rubbish disposed of appropriately
   • Workplace documentation is completed
