Recent Work

Major Events & Festivals

We support organisers of large-scale events and festivals with crowd safety planning, modelling and post-event review, helping teams design routes, capacities and contingency plans that stand up to scrutiny.

Stadiums & Arenas

Our methods are used in stadiums and arenas to assess safe capacities, entry and exit strategies, and emergency egress, giving operators a defensible basis for safety certification and licensing.

City Centres & Transport

We advise city authorities and transport operators on crowd flows through streets, public squares and transport hubs, incorporating events, seasonal peaks and planned works.

Religious & Mass Gatherings

From religious gatherings to demonstrations and public celebrations, we apply structured crowd risk analysis to high-density, high-consequence environments where failure is not an option.
