What is a BAL Assessment?
A BAL assessment is a process to determine the potential exposure of a building to radiant heat, ember attack and direct flame contact. It is undertaken in accordance with Australian Standard 3959 and is a key requirement for designing and constructing in bushfire-prone areas.
Unsure if You Need a BAL Assessment?
If you are building, renovating, or purchasing in a bushfire-prone area, a BAL assessment is typically required as part of the planning and building approval process.
