Step 5: Determination of Bushfire Attack Level (BAL)

                         North East           South-West          South-East            North-West
 BAL value for
                         BAL- 12.5            BAL- LOW            BAL- LOW              BAL- LOW
 each face


The highest BAL category found applies. The BAL for Site 229 and 230 is BAL-12.5 all
sides of Dwelling. No reduction for shielding permitted at BAL-12.5.
Per Appendix G 4 of AS 3959-2009, the Bushfire Attack Level (BAL) is

BAL-12.5           The risk is considered to be LOW.

There is a risk of ember attack. The construction elements are expected to be exposed to a heat flux
not greater than 12.5 kW/m2.

Step 6: Determine the appropriate construction requirements, per Table 3.1
