5.0      SETBACKS
5.1      NATIONAL CONSTRUCTION CODE
         Performance Provision P2.7.5 of the National Construction Code which provides direction on the
         standard for construction requires a Class 1 building or a Class 10a building or deck associated
         with a Class 1 building that is constructed in a designated bushfire prone area must, to the degree
         necessary, be designed and constructed to reduce the risk of ignition from a bushfire, appropriate
         to the—
         (a) potential for ignition caused by burning embers, radiant heat or flame generated by a bushfire;
             and
         (b) intensity of the bushfire attack on the building.

         A designated bushfire area in Queensland is defined as Land which has been designated under a
         power of legislation as being subject, or likely to be subject, to bushfires. Both Council’s Bushfire
         hazard overlay mapping and the SPP both nominate the allotment as being subject to a medium
         potential bushfire intensity or within an adjacent potential impact buffer area.

         Section 3.10.5.0 Application of the Code states as follows:
         (a) Subject to (b), Performance Requirement P2.7.5 is satisfied for:
             • A Class 1 building; or
             • A Class 10a building or deck associated with a Class 1 building
             located in a designated bushfire prone area if it is constructed in accordance with-
             • AS3959; or
             • NASH Standard – Steel Framed Construction in Bushfire Areas.
         (b) The requirements of (a) do not apply when, in accordance with AS3959, the classified
             vegetation is Group F rainforest (excluding wet sclerophyll forest types), mangrove
             communities and grasslands under 300mm high.

         As the vegetation adjacent to the site comprises rainforest, the National Construction Code does
         not require consideration of BAL construction standards to apply.

5.2      EXPOSURE TO RADIANT HEAT
         While an assessment to determine construction standards under AS3959 (Australian Standard
         3959 (2018) Construction of buildings in bushfire-prone areas) is not required for rainforest, there
         remains a risk for fire impacts on the property on the basis of the local hazard mapping prepared
         as part of this assessment. Modelling has been undertaken to determine the exposure to radiant
         heat associated with buildings constructed on the site. The outcomes of the modelling have been
         summarised in tabulated format below.
