NCC Version:
NCC 2022 – Volume Two
Area of NCC Requirements:
- Part 3.7.2: Fire Separation and Fire Resistance – addresses external fire spread between buildings, especially concerning walls within close proximity to boundaries or other structures.
- Performance Requirements P2.2.1 and P2.3.1 are the core criteria being evaluated, with specific reference to:
- Fire spread between buildings.
- Protection of openings (e.g., windows, doors).
- Non-combustibility and resistance of external walls.
Problem:
The central issue arises from inconsistencies and a lack of clarity in applying the FSVM for demonstrating compliance with performance requirements. Variations in interpretation have led to delays, increased costs, and difficulty in achieving consistent outcomes across projects. This undermines the reliability and efficiency of performance-based approvals.
Solution:
To resolve these issues, the ABCB (Australian Building Codes Board) developed guidance through this Public Service Announcement (PSA) that clarifies the appropriate application of FSVM, outlines key principles for its use, and provides direction on how to document and conduct a PBDR process effectively. It emphasizes early stakeholder engagement, structured documentation, and alignment with Schedule 7 and A2.2(4) criteria to streamline compliance.
Finalised Report:
The final report offers a structured pathway for practitioners to prepare and review fire safety performance solutions using the FSVM. It ensures that these solutions are adequately justified and meet the NCC's performance requirements, enhancing the quality, consistency, and efficiency of building approvals involving alternative solutions. The PSA serves as a reference for best practices in managing fire safety design compliance under NCC 2022.
