What is a Bushfire Attack Level (BAL)?

A Bushfire Attack Level is a measure of the severity of a building’s potential exposure to ember attack, radiant heat and direct flame contact in a bushfire event. This rating is used for building purposes to provide a basis for establishing construction requirements to improve the protection of a building from bushfire attack.

The BAL takes into consideration several factors including the Fire Danger Index, the slope of the land and the vegetation surrounding a property.

If you’re planning to build or subdivide in a bushfire prone area you will likely need a BAL report. We strongly suggest you contact us before you submit to council. We can develop a simple plan to create the best possible outcome.

Six Levels of Bushfire Attack

There are six BAL categories ranging from low risk to extreme flame zone as shown below:

BAL – LOW
There is insufficient risk to warrant any specific construction requirements but there is still some risk
BAL – 12.5
Ember attack
BAL – 19
Increasing levels of ember attack and burning debris ignited by windborne embers together with increasing heat flux between 12.5 and 19 kilowatts m2
BAL – 29
Increasing levels of ember attack and burning debris ignited by windborne embers together with increasing heat flux between 19 and 29 kilowatts m2
BAL – 40
Increasing levels of ember attack and burning debris ignited by windborne embers together with increasing heat flux with increased likelihood of exposure to flames
BAL – FZ (FLAME ZONE)
Direct exposure to flames from fire front in addition to heat flux and ember attack

Who needs a BAL Assessment?

Under the Australian Standard AS 3959-2009 (Construction of Buildings in Bushfire Prone Areas) and BCA (Building Code of Australia), all new residential buildings located within a bushfire prone area must have a BAL assessment before planning or building permits can be issued. This includes additions to buildings within 6 metres of a dwelling such as sheds, patio’s, extensions, etc.

How can we help reduce your BAL level?

As your individual BAL level increases so do your construction costs. Each BAL rating has its own special construction requirements including regulations of the materials used and the inclusion of additional safety features.

We specialise in providing BAL assessments for all types of development and subdivision projects and can assist you in lowering your rating to save you money. With over 12 years of experience, our skilled assessors know exactly what legal conditions are required for your area. We can develop a tailored plan based on your individual requirements to reach the best possible solution for your property.

We use professional high-tech equipment including aerial drones to quickly and accurately identify surrounding fuels of the proposed build.
