What is Structural Fire Engineering

Evidence-based fire resistance. Performance-driven design.

Design boldly and build smart.

Structural Fire Engineering (SFE) is the science of assessing how a building’s structure will behave during a fire. It goes beyond prescriptive codes to deliver performance-based solutions using advanced modelling, heat transfer analysis, and engineering judgement. SFE is essential for validating fire resistance in complex, unconventional, or existing structures — supporting safe evacuation and emergency response.

Specialist Support

At Kiwa Fire Safety Compliance, we offer a range of specialist services designed to help you assess, justify, and optimise the fire resistance of your building’s structure.

Desktop Studies

Assess non-tested or non-standard construction details using engineering judgement, tabulated data, and advanced modelling to determine fire resistance.

Numerical Modelling

Simulate fire scenarios using finite element analysis to predict how structural elements behave under thermal and mechanical stress.

Site Inspections

Evaluate the inherent fire resistance of existing structures during construction, refurbishment, or change of use, based on on-site observations and documentation.

Third-Party Reviews

Provide independent, expert validation of fire engineering reports to support compliance, quality assurance, or regulatory approval.

Technical Advice

Offer tailored guidance to design teams, insurers, and regulators on fire resistance strategies, performance-based design, and compliance pathways.

When is SFE most valuable?

Structural Fire Engineering is essential when:

Assessing Existing Buildings

Evaluate the fire resistance of structures during refurbishment or change of use, identifying whether additional protection is needed to meet current standards.

Non-Standard Materials or Mixed Systems

When using hybrid or unconventional materials, SFE ensures fire performance is properly assessed beyond standard guidance.

Non-Tested or Unusual Details

For construction details not covered by existing fire test data, SFE provides engineering analysis to justify their use and performance.

Performance-Based Design or Engineering Judgement

When prescriptive codes don’t apply, SFE enables a flexible, evidence-led approach to demonstrate compliance through validated modelling.

Standards & Regulations We Work To

Our structural fire engineering services are grounded in the most recognised codes and performance-based frameworks — ensuring every solution is technically sound, regulation-ready and tailored to your project.

Frequently Asked Questions

Q: Can you assess existing buildings?

A: Yes. We conduct site inspections and desktop studies to evaluate fire resistance during refurbishment or change of use.

Q: What modelling techniques do you use?

A: We use finite element analysis, CFD, and heat transfer simulations aligned with Eurocode and BS standard

Q: How does Structural Fire Engineering help me meet Building Regulations?

A: Our performance-based approach ensures compliance with UK Building Regulations and recognised standards like Eurocode and BS 7974, giving you confidence in regulatory approval.

Q: Can you support projects during design and construction stages?

A: Yes. We work with design teams early to optimise fire resistance strategies and provide validation during construction for peace of mind.

Q: Will using Structural Fire Engineering reduce costs without compromising safety?

A: Absolutely. By avoiding unnecessary over-specification, we help you achieve compliance and safety while minimising material and protection costs.

Q: Do you provide independent third-party reviews for fire engineering reports?

A: Yes. Our impartial reviews are widely accepted by building control, insurers, and approval bodies.

Q: Can you assess existing buildings for refurbishment or change of use?

A: Yes. We conduct site inspections and desktop studies to evaluate fire resistance in existing structures.

Q: What types of projects benefit most from Structural Fire Engineering?

A: Complex designs, high-rise buildings, refurbishment projects, and structures using innovative materials or hybrid systems often require performance-based fire assessments.

Q: How early should I involve Structural Fire Engineering in my project?

A: Ideally at concept or design stage to maximize design flexibility and cost efficiency. However, we can also get involved at later stages of construction to review fire resistance strategies, validate compliance, and provide independent assessments if design changes or regulatory queries arise.

Q: Are your methods recognised by insurers and approval authorities?

A: Yes. Our evidence-based approach and compliance with international standards make our reports trusted by regulators and insurers.
