Selections
Mandatory
Mandatory

As per current NATSPEC except as follows: 

Performance Criteria
Selections should be based on the following performance criteria:

  • Offer value for money in a Whole of Life framework;
  • Provide comfort for students who may undertake floor based activities
  • Have appropriate aesthetic appeal
  • Offer high durability and robustness
  • Provide appropriate functionality for the location and use of the area including:
  • Acoustic suitability to expected background and activity noise levels
  • Tactile comfort in relation to the usage of the room.
  • Support sustainability by having recycling potential at the end of usable life, and/or include recycled content.
  • Compliance with NCC Fire Hazard Properties and CRF/SD requirements listed in 4.1 Schedules
  • Carpets must be graded  by the Australian Carpet  Classification Scheme (ACCS).  ACCS licensees give a warranty with their carpets; this warranty is subject to proper installation and maintenance procedures (AS 2454 and AS 2455 will apply).  The ACCS licensee’s instructions for underlay should must be followed.
  • Low VOC emissions in line with the VOC limits stipulated in the Green Star Buildings rating tool
  • Carpet tiles are preferred to broadloom carpet.
  • Location of carpet tile and carpet to be determined in consultation with School Principal :
    • Primary Schools – homebases, libraries, administration and staff rooms
    • SSP – homebases, libraries, administration and staff rooms
    • Secondary Schools – learning spaces, libraries, administration and staff rooms.Where carpet tiles are installed, provide floor cushions (lily pads) and wool rugs for every Primary and SSP Home Base to facilitate floor based activities.
