Fire Safety Verification Method
• The Verification Method states that the Performance Solution is to be developed by a fire safety engineer
• Requires development of a Performance Based Design Brief (PBDB) to ensure collaboration between all stakeholders
• Specifies design fire scenarios that must be considered• In all cases, equivalence with Deemed-to-Satisfy
Provisions must be demonstrated

Fire Safety Verification Method
• Specific education program (mid 2019)• Will be supported by a comprehensive handbook• 2020 NCC Information Seminars (early 2020)
