Evacuation Modelling
At SILFire, evacuation modelling is a key service that supports the development of safer, smarter building designs. By simulating how people move during emergencies, we help design teams understand evacuation performance under realistic conditions. Using software like Pathfinder, we assess how long it takes for occupants to evacuate, where congestion may occur, and whether the exit capacity is adequate.
We model a wide range of emergency scenarios, including blocked exits, smokeobstructed routes, and mobility-impaired occupants. These studies are essential for high-risk and high-occupancy buildings such as airports, malls, stadiums, and hospitals, where prescriptive code alone may be insufficient. Our deliverables include datadriven reports and visual outputs that support stakeholder understanding and help secure authority approvals.
SCENARIO-BASED EVACUATION ANALYSIS
- Simulate emergency conditions such as blocked exits or smoke-obstructed paths
- Model occupant behavior under delayed response and high-density conditions
- Assess evacuation times, route viability, and compliance with design assumptions
COMPLIANCE & SYSTEM COORDINATION
- Align egress strategy with UAE Fire Code, NFPA 101, and IBC
- Validate exit widths, travel distances, and egress capacity
- Coordinate findings with fire alarm, emergency lighting, and smoke control systems
BEHAVIORAL SIMULATION
- Simulate occupant movement through stairwells, corridors, and exit routes.
- Account for walking speeds, visibility loss, congestion, and alarm reaction
- Evaluate special conditions like lift unavailability or phased evacuation
AUTHORITY APPROVAL SUPPORT
- Provide clear, visual simulation outputs and time-based data.
- Aid design reviews using stakeholder presentations together with authority engagement.
- Justify alternate egress approaches through performance-based evidence.
