Protocols for Mitigating Cladding Risk (PMCR) – Part B: Cladding Risk Prioritisation Model Methodology for Combustible Cladding in Victoria – Cladding Safety Victoria

This record contains Part B of the Protocols for Mitigating Cladding Risk (PMCR): the Cladding Risk Prioritisation Model (CRPM) Methodology documents developed by Cladding Safety Victoria (CSV).

Part B comprises:

• B.01 – CRPM Overview and Approach
• B.02 – Risk Prioritisation Method

These documents explain the purpose, design principles, risk framework and technical methodology used by CSV to assess and prioritise combustible cladding risk on Class 2 and Class 3 buildings in Victoria.

The CRPM was developed to support a risk-based approach to prioritisation by identifying where combustible cladding contributes most significantly to fire risk and potential harm to occupants. It uses available building risk data, expert judgement and structured assessment methods to support the assignment of buildings to cladding risk levels and to inform sequencing for remediation consideration.

Part B provides the risk assessment methodology that supports the broader PMCR document set. It establishes the CRPM structure used to assess cladding risk and assign buildings to risk levels, providing a methodological basis for the related PMCR parts, including:

• Part A – Authorisation, which codifies the Victorian Government decisions that enable PMCR activation;
• Part C – PMCR Foundation, which defines the PMCR method, objectives and key design tasks;
• 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, the CRPM explains how cladding risk is considered through concepts such as cladding risk premium, IF-SCAN, baseline building protection, risk profiles, cohort coding and priority risk cohort lists. These concepts help connect the PMCR’s authorising framework, risk rationale, policy settings, intervention options and implementation processes.

The documents should be read as technical methodology documents within the PMCR framework. They should not be read as standalone building assessments, compliance determinations, remediation approvals, funding decisions or universal risk ratings for any individual building. Rather, they document the methodology used by CSV to structure and inform cladding risk prioritisation as part of Victoria’s broader combustible cladding risk mitigation program.
