Effective fire safety requires informed decisions at both the design and assessment stages. New developments need a clear understanding of building codes and fire safety objectives, while existing buildings may require investigation when façade materials create potential fire concerns. Building code consultant canada services support project teams by providing plan reviews and fire safety strategies based on applicable building codes and standards. Vortex Fire considers fire prevention, fire protection, fire safety management, compartmentation, structural fire resistance, means of egress, smoke management, and external fire spread when developing appropriate strategies. For existing buildings, cladding fire risk can require a different technical approach. Vortex Fire provides a staged assessment process involving document review, site investigation, laboratory screening, quantitative fire engineering, evacuation analysis, mitigation planning, and remedial support where required. This evidence based process helps stakeholders understand risk and make informed decisions.

Reviewing Codes Before Design Decisions Are Finalized

Building code compliance becomes much easier to achieve when requirements are known prior to making significant design decisions. Project specific review can highlight important fire safety issues and give direction for further design development.

Vortex Fire performs plan review to verify compliance with a number of building codes and standards including National Building Code of Canada, Alberta Building Code, British Columbia Building Code, Ontario Building Code and numerous international building and fire codes.

Plan review can cover topics such as building and occupancy classification, fire services, compartmentation, structural fire resistance, exterior fire spread, means of egress, fire protection system and smoke control system.

This allows the project team to see how different requirements interact with each other. For example, building occupancy and building construction have an effect on fire resistance and means of egress requirements, while building facade impacts exterior fire spread requirements.

Early review also reduces risks of non-compliance, abortive work and overdesign. A professional approach creates better foundation for further specification and construction.

Creating a Fire Strategy That Supports Long Term Safety

Fire Safety Strategy will help to integrate all protective measures into an integrated whole within well-defined fire safety objectives. Such a strategy should be specific to the particular building in question and not rely on general assumptions.

The Strategy Service by Vortex Fire may cover fire safety objectives, design criteria and applicable standards, building and occupancy classification, fire services provisions, compartmentation, structural fire resistance, external fire spread, means of egress, fire protection systems, smoke control, construction quality assurance, fire safety during construction and fire safety management.

In case of Performance Based Design approach being chosen, the strategy will be supplemented by fire engineering analysis like fire modeling, evacuation modeling, structural fire engineering or radiation analysis.

Strategy will also have to be effective even after construction is complete. Maintenance and management controls are essential, since the fire safety systems and features of the building need to continue working for the entire life cycle of the building.

Strategy will provide valuable information for the owner/facility manager about the underlying fire protection philosophy. For the designer/contractor, it will serve as a point of reference.

Identifying Fire Hazards Within Building Cladding

External cladding can create significant fire safety concerns when combustible materials are incorporated into a façade system. The risk is particularly important because an external fire can spread vertically or horizontally across a building.

Vortex Fire highlights the risks associated with combustible cladding and explains that international incidents have resulted in significant property damage and loss of life.

Aluminium composite panels may contain thermoplastic cores such as polyethylene. Under fire conditions, thermoplastic materials can melt and contribute to fire spread. Other materials, including thermoset polymers such as polyurethane and polyisocyanurate, can show different fire performance.

However, assessing risk requires more than identifying one material. The complete façade system should be considered, including cladding layers, insulation, cavity spaces, fire barriers, connections, and available testing evidence.

Existing buildings can be difficult to assess when original documentation is incomplete. A professional audit can establish the available evidence and determine whether laboratory testing or detailed engineering analysis is required.

Conducting the Initial Cladding Investigation

Vortex Fire's first assessment stage begins with reviewing available as built information and conducting a site visit. This helps establish the extent of the cladding and understand the existing fire strategy.

If combustible cladding is found, or if adequate information is not available, laboratory screening can be undertaken. Small samples are removed from the existing building and submitted to a third laboratory.

This approach is relatively non invasive and can provide useful information without immediately requiring extensive destructive investigation.

Vortex Fire identifies several laboratory techniques. Thermogravimetric analysis can examine thermal decomposition. FTIR ATR and SEM EDS can help determine chemical composition.

The laboratory results provide a technical basis for a preliminary façade fire assessment report. The report can indicate whether additional assessment is needed or whether the available evidence supports acceptance of the existing cladding.

This staged process allows the level of investigation to be matched to the evidence and the potential risk.

Measuring External Fire Risk Through Engineering Analysis

If the initial assessment suggests that further study is needed, quantitative fire engineering could be carried out. In describing this step, Vortex Fire states that it is an assessment of fire risk potential with laboratory findings and fire engineering assessment.

In the assessment, consideration will be made on how fast the external fire would spread, and under what condition occupants and firefighters would no longer be safe.

Evacuation analysis is an essential part of the assessment process. Occupant's evacuation time from each floor and the whole building is estimated based on Required Safe Egress Time calculation.

The Required Safe Egress Time could then be contrasted with Available Safe Egress Time, which is the time before conditions become too unsafe to evacuate.

The link between fire behavior and evacuation is the technical aspect that gives understanding about the risk of an external building fire.

With the information obtained, people would be able to make informed decision without merely assuming the facts.

When it comes to risk reduction, mitigation steps could be developed in short, medium, and long terms.

Supporting Risk Reduction and Remedial Solutions

Fire Risk Assessment is more meaningful where the result of the analysis will be put into practice. In cases where there is a need for some remedy, the chosen measure must deal with the identified risk and at the same time be aligned with the goals of fire safety of the building.

Assistance in remedial work is provided by Vortex Fire through construction documentation review, inspection, and technical assistance.

The construction documentation review may be helpful in assessing whether the chosen remedy addresses the identified risk related to the façade. The site inspection may be helpful in confirming that the work is done according to plan.

This step provides a link between assessment and remediation where laboratory analysis, fire engineering assessment, evacuation assessment and the suggested remedy can be used in the process of correction.

The professional engagement may also enhance the communication between different parties involved in the project such as the owners, contractors and consultants.

The proper documentation of the whole process of assessment and remediation can be helpful in creating the record of the process.

The ultimate aim here is the reduction of fire risk via technical measures.

FAQs

What does a fire safety strategy achieve?

It establishes the overall fire prevention, protection, evacuation, management, and compliance approach for a specific building.

Why can cladding create external fire risk?

Certain combustible façade materials can contribute to fire spread across the exterior of a building.

What happens if cladding information is unavailable?

A site investigation and laboratory screening can help establish material characteristics and determine whether further assessment is required.

Why are ASET and RSET important?

They provide a technical comparison between the time available for safe evacuation and the time occupants require to leave.

Can technical support continue after a cladding assessment?

Yes. Where remedial work is necessary, construction documentation can be reviewed and inspections and technical support can be provided during implementation.
