Omnii’s Role as Expert Witness in Navigating Combustible Cladding Challenges
Omnii
Omnii was recently engaged as an expert witness in a significant Building Appeals Board (BAB) case regarding non-compliant cladding in a multi-unit development. This landmark ruling highlights the complexity of integrating combustible cladding materials within modern construction while achieving compliance with fire safety regulations. The decision underscores the necessity for expert interpretation of fire safety principles and the application of pragmatic solutions within legal and regulatory frameworks.
Our involvement in this case focused on providing expert technical insight and guidance to support the safe and compliant acceptance of combustible cladding. By leveraging our deep knowledge of fire engineering and regulatory compliance, we support developers, designers, and regulatory bodies in achieving balanced outcomes.
Insights from the BAB Decision
The BAB ruling reinforces several key principles relevant to combustible cladding, including:
The Importance of Holistic Assessment
Cladding cannot be evaluated in isolation; its fire performance must be considered within the broader fire safety strategy of the building.
Evidence-Based Advice
Successful acceptance of combustible cladding requires robust technical evidence and expert testimony to address concerns raised by certifiers, regulators, and other stakeholders.
Avoiding Blanket Prohibitions
A nuanced approach allows for safe, compliant use of combustible materials while supporting architectural and functional aspirations.

Omnii’s Expert Witness Role
Omnii plays a critical role as an expert witness in cases involving cladding compliance and fire safety. Our contributions include:
Providing Objective, Evidence-Based Analysis
Our team delivers detailed evaluations of combustible cladding systems, their integration with building fire safety measures, and their compliance with the National Construction Code (NCC) and relevant performance standards.
Offering Pragmatic Recommendations
We advise on strategies to address non-compliance, balancing regulatory requirements with practical considerations for remediation or acceptance.
Supporting Appeals and Expert Advice
Our expert reports and testimony help project stakeholders navigate the appeals process, presenting clear, defensible arguments to regulatory bodies such as the BAB.
A Pragmatic and Holistic Approach to Cladding Compliance
Omnii’s approach to combustible cladding is rooted in a pragmatic understanding of both fire safety and the legal context. We adopt a holistic perspective, ensuring that cladding is evaluated as part of an interconnected system. Key aspects of our methodology include:
System-Wide Risk Assessments
We assess cladding materials in conjunction with fire safety systems such as sprinklers, smoke control, and egress provisions to provide a comprehensive understanding of their impact.
Advanced Fire Modelling
Utilising cutting-edge tools, we simulate fire scenarios to demonstrate the performance of cladding within the building’s overall fire safety strategy.
Technical Advice
Our expertise allows us to bridge the gap between technical evidence and regulatory requirements, ensuring stakeholders understand and accept proposed solutions.

Enhancing Outcomes through Expertise
Our expert witness services offer tangible benefits to stakeholders, including:
Regulatory Confidence
By addressing safety concerns with clear, evidence-backed arguments, we facilitate the acceptance of alternative solutions and performance-based designs.
Cost-Effective Compliance
Omnii’s recommendations often minimise the need for extensive remediation, reducing project delays and associated costs.
Risk Mitigation
Our expert guidance ensures compliance with safety standards, reducing liability for developers and building owners.

Pioneering a Balanced Approach to Combustible Cladding
As the industry grapples with the challenges of combustible cladding, Omnii’s role as an expert witness is pivotal in shaping a path forward. Our ability to provide objective analysis, expert opinion, and pragmatic solutions ensures that stakeholders achieve safe, compliant, and economically viable outcomes.
The BAB ruling is a reminder of the evolving demands of fire safety in modern construction. With Omnii’s legal and technical expertise, we enable clients to navigate these complexities with confidence, delivering results that prioritise safety and align with regulatory expectations while preserving the integrity of their projects.
