Bushfire Attack Level Report v1                                                   NCES REF: J000756
Lot 17 on RP903874 – 268 Kinmond Creek Rd, Cootharaba




6.0 CONCLUSION

The dwelling proposed to be constructed at 268 Kinmond Creek Road, Cootharaba, has been
assessed as being exposed to BAL FZ. BAL FZ is primarily concerned with protection from flame
contact together with ember attack and radiant heat of more than 40 kW/m2.
Construction in BAL FZ may require reliance on measures other than construction. The
requirements for construction of a building in BAL FZ may be regulated by the building authorities
having jurisdiction in the States and Territories of Australia.
A building assessed as being BAL FZ shall comply with Section 3 and Clauses 9.2 to 9.8 of
AS3959:2018 and have a minimum setback of 10m from the edge of the classified vegetation.
There are a number of Standards that specify requirements for construction; however, where
AS3959 2018 does not provide construction requirements for a particular element, the other
Standards apply.
Any element of construction or system that satisfies the test criteria of AS 1530.8.2 may be used
in lieu of the applicable requirements contained in Clauses 9.2 to 9.8 of AS 3959 2018.
An application for additional vegetation clearing can be made to NSC to increase the separation
distance hence lower the resultant BAL acting on the building. The extent of proposed vegetation
clearing should be identified on the proposed building plans. Generally, NSC is amenable to
approving vegetation clearing to secure no less than BAL 29.
Table 4 should be used to determine necessary separation distances in each direction to achieve
lower BAL ratings. In accordance with AS3959, the most severe BAL assigned to an elevation is
to be assigned to the entire dwelling.
All queries regarding building materials should be discussed with the architect and/or
building designer and confirmed to be compliant with the requirements of the AS
3959:2018 by a registered building certifier.
