A Lower-Austrian fire-protection engineering practice (working with simulation since 2005) specialising in fire and evacuation simulation alongside fire-protection concepts and plans. It runs field-model fire and smoke simulations with the Fire Dynamics Simulator (FDS) — including 3D laser-scan modelling and cluster computation — as a specialist subconsultant to fire-protection offices across the DACH region. Its simulations inform, rather than replace, the professional judgement of the appointed fire engineers.
