and in a Potential Bushfire Impact Buffer area on Queensland Potential Bushfire Intensity mapping.
Therefore, the house is deemed to potentially be in a Bushfire Prone Area and an assessment of the
bushfire risk to the building and a bushfire risk management plan is required.
Assessment of Bushfire Prone Area status
The assessment of Potential Bushfire Impact Buffer Class confirms that:
    • The house is deemed to be in a Bushfire Prone Area.
As the the house is in a Bushfire Prone Area, an assessment of the Bushfire Attack Level using
Australian Standard AS3959 Construction of buildings in bushfire prone areas is required to be
conducted as specified by the Queensland Building Act and the bushfire requirements of the
National Construction Code.
Assessment of the Bushfire Attack Level
The Bushfire Attack Level (BAL) for the house using Method 2 of Australian Standard AS3959
Construction of buildings in bushfire prone areas was assessed as:
   • BAL 12.5 for all building elevations.
Assessment of vegetation clearing
    •    No clearing of vegetation with conservation significance is required to achieve the bushfire
         mitigation solution in this plan

         dwelling or a permanent dam.
Recommendations for Australian Standard AS3959
Australian Standard AS3959 Construction of buildings in bushfire-prone areas specifies Deemed to
Satisfy bushfire resistant methodologies based on the assessed Bushfire Attack Level.
It is recommended that:
    •    The building solution for all building elevations to address the Deemed to Satisfy
