What should I include in a scope for a bushfire consultant?

Summary: Assesses bushfire risk and sets the Bushfire Attack Level (BAL) under AS 3959, which decides construction requirements.

Why it matters: A higher BAL can add significant cost to windows, cladding, decks and roofing. BAL-40 and Flame Zone may trigger extra approvals.

When needed: The site is mapped bushfire prone, or council/certifier asks.

Minimum scope by stage

• Design: site inspection; vegetation and slope assessment; BAL assessment and certificate to AS 3959; construction requirements summary for the designer
• Planning (if required): bushfire report or management plan; asset protection zone, access and water supply requirements
• Building approval: review that drawings and specification show the BAL construction requirements
• Completion: compliance letter where council or the certifier requires it; confirmation the asset protection zone is in place

Options

• Design advice to lower the BAL (siting, setbacks, vegetation management)
• Performance-based assessment for BAL-40 or Flame Zone sites
• Vegetation management plan

Meetings and site visits: One site visit; a completion visit if a compliance letter is needed.

Watch-out: Accreditation rules differ by state (e.g. NSW RFS-recognised consultants, WA accredited assessors). BAL certificates can expire, and siting changes can change the BAL.
