Protocols for Mitigating Cladding Risk (PMCR) – Part C: PMCR Foundation and Design Concept for Combustible Cladding Risk Mitigation in Victoria – Cladding Safety Victoria

This record contains Part C of the Protocols for Mitigating Cladding Risk (PMCR): the PMCR Foundation document developed by Cladding Safety Victoria (CSV) as part of Victoria’s risk-based framework for addressing combustible cladding risk on relevant Class 2 and Class 3 buildings.

Part C comprises:

• C.01 – PMCR Design Concept

This document defines the PMCR method, objectives and key design tasks. It explains the design logic, scope and rationale for applying a proportionate, risk-based approach to combustible cladding mitigation, including circumstances where targeted interventions may be used instead of full removal and replacement of all combustible external cladding.

Part C builds on the authorising framework in Part A and the risk assessment methodology in Part B, and provides the design foundation for the related PMCR parts, including:

• Part A – Authorisation, which codifies the Victorian Government decisions that enable PMCR activation;
• Part B – CRPM Methodology, which specifies the Cladding Risk Prioritisation Model used to assess cladding risk and assign buildings to risk levels;
• Part D – Support Packages, which capture the risk knowledge and science-based findings used to systemise and calibrate PMCR application;
• Part E – CSV Cladding Risk Policy, which establishes key CSV policy positions in relation to cladding risk;
• Part F – PMCR Interventions, which identifies the interventions that may be used to mitigate combustible cladding risk; and
• Part G – Implementation, which specifies the standards and procedures that guide PMCR application.

CSV’s cladding fire testing program also forms part of the broader technical evidence base informing the PMCR. The test reports provide practical evidence of cladding and wall-system fire behaviour under defined conditions, supporting a risk-based approach grounded in observed fire performance.

Separately published peer review material and CSV responses provide additional assurance for the PMCR methodology. These reviews considered the methodology, reasoning, risk approach and proposed interventions, with CSV responses showing how feedback was considered in refining the document set. This supports transparency and provides further confidence in the technical basis and practical application of the PMCR.

In particular, Part C explains key PMCR concepts including Acceptable Cladding Risk, cladding clusters, threat-barrier analysis, baseline risk, risk mitigation interventions, cladding remediation standards and the relationship between cladding risk assessment, policy and implementation.

The document should be read as a foundation and design concept document within the PMCR framework. It should not be read as a standalone building assessment, compliance determination, remediation approval or universal risk rating for any individual building. Rather, it explains the design foundation for how combustible cladding risk is assessed, mitigated and implemented through Victoria’s broader PMCR framework.
