How a Fire Engineer Can Help Reduce Construction Costs

Fire engineering is not just about ensuring compliance and safety—it’s also a valuable tool for optimizing construction costs. By adopting performance-based approaches, fire engineers can help developers, architects, and contractors save money while maintaining high safety standards. This article explores the ways in which fire engineers contribute to cost-efficient construction, without compromising fire safety.

1. Performance-Based Design: Optimizing Solutions

Traditional prescriptive fire safety codes can sometimes impose unnecessary costs due to rigid requirements. Fire engineer use performance-based fire engineering to tailor solutions that:

Focus on Actual Risks: Fire engineers assess the specific fire risks associated with a project rather than applying generalized standards.

Allow Design Flexibility: By using advanced modeling tools like Computational Fluid Dynamics (CFD), fire engineers demonstrate how alternative solutions can meet or exceed safety requirements.

Example: Instead of requiring fire-resistant materials throughout an entire building, fire engineers may justify their use in high-risk areas only, reducing material costs.

2. Strategic Material Use

Fire engineers help reduce costs by optimizing the selection and placement of materials:

Targeted Use of Fire-Resistant Materials: Fire engineers identify where fire-resistant materials are necessary and where standard materials can be safely used.

Efficient Insulation Design: By understanding fire dynamics, fire engineers can design insulation systems that meet fire safety standards without over-engineering.

Example: For a multi-story building, fire engineers may demonstrate that non-combustible cladding is only needed on specific levels, reducing the volume of premium materials required.

3. Optimizing Fire Resistance Levels (FRLs)

Fire Resistance Levels (FRLs) define how long a building element can withstand fire. Prescriptive codes often mandate high FRLs across the board, which can drive up costs. Fire engineers reduce costs by:

Analyzing Structural Requirements: Ensuring only the most critical elements maintain high FRLs.

Alternative Solutions: Incorporating fire suppression systems or compartmentation to justify lower FRLs for certain areas.

Example: Using sprinklers to reduce the required fire resistance of load-bearing walls in non-critical areas.

4. Efficient Fire Suppression Systems

Fire engineers design tailored fire suppression systems that reduce costs while maintaining effectiveness:

Right-Sizing Systems: Avoiding over-specification of sprinklers, fire pumps, and water storage tanks.

Selecting Appropriate Technology: Choosing suppression methods—such as water, foam, or gas-based systems—based on specific building risks.

Example: For a warehouse storing non-combustible goods, fire engineers may recommend a simplified sprinkler system instead of a high-cost, high-capacity design.

5. Reducing Smoke Management Costs

Smoke control systems can be expensive, especially in large buildings or high-rise developments. Fire engineers reduce these costs by:

Optimizing Ventilation: Designing smoke extraction systems that balance cost and effectiveness.

Using Natural Ventilation: Where possible, incorporating openings and natural airflow to reduce reliance on mechanical systems.

Example: In atriums, fire engineers may integrate natural vents to achieve smoke control compliance without expensive mechanical systems.

6. Streamlining Egress Requirements

Prescriptive egress requirements, such as staircases, corridors, and exits, can sometimes lead to over-design. Fire engineers optimize egress systems by:

Evacuation Modeling: Using tools to simulate occupant movement during a fire and ensure exit capacities are neither over- nor under-designed.

Strategic Placement of Exits: Reducing the number of required exits by demonstrating safe evacuation through alternative routes or designs.

Example: In a high-rise building, fire engineers may justify fewer stairwells by designing pressurized staircases to prevent smoke ingress.

7. Retrofitting and Upgrades for Cost Savings

In existing buildings, fire engineers assess the need for upgrades and propose cost-effective solutions:

Targeted Retrofits: Upgrading only critical components instead of overhauling entire systems.

Alternative Compliance Pathways: Proposing performance-based solutions to avoid costly reconstruction.

Example: For a heritage building, fire engineers may recommend fire-resistant coatings or discreet suppression systems instead of replacing original materials.

8. Simplifying Regulatory Approval

Delays in regulatory approval can lead to increased costs. Fire engineers streamline the approval process by:

Providing Comprehensive Documentation: Ensuring that fire safety designs meet all necessary requirements.

Collaborating with Authorities: Engaging with regulatory bodies early in the project to address potential concerns proactively.

Example: Fire engineers in Brisbane ensure compliance with the National Construction Code (NCC) and Queensland Fire and Emergency Services (QFES) standards, avoiding costly project delays.

9. Avoiding Overdesign

Overdesign occurs when excessive safety margins lead to unnecessary costs. Fire engineers avoid this by:

Detailed Risk Assessments: Identifying the actual risks and designing systems to address them efficiently.

Custom Solutions: Balancing safety and cost by designing for specific building uses and occupant behaviors.

Example: A small office building may not need the same fire suppression capacity as a large industrial warehouse, and fire engineers ensure the system is right-sized.

10. Long-Term Cost Savings

Fire engineers design systems that minimize not only initial construction costs but also long-term expenses:

Durable Materials and Systems: Selecting components that require less maintenance and have longer lifespans.

Energy-Efficient Systems: Integrating fire safety systems with energy-efficient HVAC designs to reduce operating costs.

Example: Fire engineers may incorporate low-maintenance fire suppression systems or smoke control solutions that also improve building energy efficiency.

Real-Life Example of Cost Savings

Case Study: Retrofitting a Mixed-Use Development in Brisbane

 A developer in Brisbane sought to retrofit a mixed-use building to comply with updated fire safety standards without exceeding budget. Fire engineers achieved cost savings by:

Conducting a fire risk assessment to identify critical areas requiring upgrades.

Proposing non-combustible coatings for cladding instead of full replacement.

Optimizing the sprinkler system design based on the building's fire load and risk profile.

The result was a compliant, safe, and cost-efficient retrofit that saved the developer significant costs compared to a full overhaul.

Conclusion

Fire engineers are invaluable in reducing construction costs by optimizing fire safety solutions tailored to specific projects. Through performance-based design, strategic material use, efficient systems, and regulatory expertise, fire engineers help developers and builders achieve significant cost savings without compromising safety or compliance.
