Site Bushfire Attack Assessment

1.0 Introduction

The assessment of the proposed site is carried out to determine the category of bushfire attack in
accordance with Australian Standard AS 3959-1999 Construction of Buildings in Bushfire-Prone Areas.
The site has been identified as being in a bushfire risk area via town plan mapping. Although the town
plan does not contain construction requirements for bushfire prone areas the requirements contained in
the Building Code of Australia (BCA) Volume 2 are triggered.

Categories of bushfire attack are determined so that the appropriate vegetation separation distances and
levels of bushfire construction can be applied to the particular site/ proposed building works. Extreme
levels of attack (i.e. greater than those designated as ‘high’) are outside the scope of AS 3959-1999 and,
therefore specific design and construction requirements should be provided to meet Performance
Requirement P2.3.4 of the BCA Volume 2. For the category of ‘low’ bushfire attack, the degree of
bushfire attack is considered insufficient to warrant specific construction requirements.

2.0 Procedure

When assessing the site to determine the vegetation separation distances and level of construction
required the following AS 3959-199 Section 2 procedure was followed:

a) Determine the vegetation separation distance, type and class, as follows:
i) Identify all vegetation in each direction from the Site for a distance of 350 metres:

ii) Consult Figure 2.1 (AS3959) copy attached to determine the vegetation type which
predominates; and

iii) Select the Predominant Vegetation Class (A to F) as described in Clause 2.2.2.

b) Determine the Separation Distance between the Predominant Vegetation Class and the Site as
described in Clause 2.2.3.
