Egress Modelling

Smart Evacuation Planning for Complex Buildings

Modern buildings present complex challenges for life safety especially in high-occupancy or large-footprint structures. Whether it’s a multi-level shopping centre, airport terminal, warehouse or stadium ensuring safe and timely occupant evacuation is critical.
At Vortex Fire, we offer expert Egress Modelling in Australia, providing data-driven analysis of human movement during emergencies. Our team uses advanced simulation tools and engineering expertise to validate evacuation strategies in alignment with the National Construction Code (NCC) and applicable Australian Standards.

What Is Egress Modelling?

Egress Modelling simulates the movement of occupants during an evacuation scenario. Using Egress Modelling Software, Australia relies on software such as Pathfinder and MassMotion—we create 2D and 3D simulations of occupant flow, density, queueing, and travel time toward exits.
This analysis helps answer key safety questions:
  • Are travel distances compliant with the NCC?
  • Do occupants reach exits before conditions become hazardous (ASET vs. RSET)?
  • Where do bottlenecks, congestion, or unsafe delays occur?
  • Can egress paths support diverse user needs, including accessibility?
Egress modelling provides clear, quantifiable insight for prescriptive and performance-based fire safety designs.

Applications of Fire and Egress Modelling in Australia

We provide Fire and Egress Modelling Australia services for:
  • High-rise residential and commercial buildings
  • Shopping centres and mixed-use precincts
  • Warehouses and industrial facilities with long travel paths
  • Airports, train stations, and transit hubs
  • Sports venues, concert halls, and auditoriums
  • Healthcare and aged care facilities
These environments often involve high occupant loads, complex layouts, and variable movement patterns. Egress analysis ensures life safety strategies remain effective under realistic fire conditions.

Integration with Fire Modelling

At Vortex Fire, we combine egress simulations with fire modelling using FDS (Fire Dynamics Simulator) tools. This integrated approach enables our engineers to analyse:
  • Smoke movement and visibility along egress paths
  • Temperature and gas concentrations
  • Safe evacuation time vs. fire growth (ASET/RSET)
  • Impact of sprinklers, alarms, and smoke exhaust systems
We deliver complete, evidence-based life safety strategies for certifiers and authorities by combining fire and egress data.

Compliant with Australian Regulations

Our work is guided by:
  • National Construction Code (NCC) – Vol 1
  • International Fire Engineering Guidelines (IFEG)
  • AS 1668.1 & 2, AS 2419, AS 3745, and other relevant standards
  • Requirements from Fire & Rescue NSW, QFES, CFA, and private certifiers
Egress Modelling Australia often supports Alternative Solutions or justifies designs where travel distances exceed prescriptive limits. Many Authorities Having Jurisdiction (AHJs) request detailed reports for approval.

Why Choose Vortex Fire?

  • Nationally trusted fire engineers and modellers
  • Experience with complex, high-risk building types
  • Proven approval track record with AHJs across Australia
  • Access to industry-leading egress modelling software that Australian professionals use
  • NCC-aligned, code-defensible reporting and analysis
We’ve supported projects in Sydney and Toronto beyond, helping clients turn complex evacuation challenges into safe, certifiable designs.
