Read-only demonstration. Four sanitised or hypothetical engineering projects. Each states its own validation status; nothing shown is engineer approved.

FIRE ENGINEERING — EVACUATION (EGRESS) MODELLING · CASE STUDY

Los Angeles Hotel Fire Evacuation — Models

NATIVE SIMULEX RESULTS (17 runs) — inputs assumed; CP1–CP4 NOT APPROVED; no ASET/fire model

Models

Geometry: a wall-only plan (DXF) prepared by Hexanta and imported into Simulex; the driver checked Simulex's wall-line count against Hexanta's and calibrated the view before placing exits and occupants. Routes are not assigned: each cabin door opens to the courtyard and Simulex chooses routes to the site exits from its distance map. Blocked exits are closed in the scenario's wall plan.

Exits

Exit	Description	Width (m)	Available in
X1	Vehicle driveway	6.00	all
X2	Creek-side footpath	1.20	all
X3	Hillside footpath	1.00	ALT-ALL only (lost to the fire front otherwise)
X4	Office front door to the car park	0.86	all
X5	New gate, courtyard to car park	2.00	ALT-EXIT, ALT-WARN-EXIT

Sanitised derivative of preserved evidence (simulex-HXM01-20261024, simulex-HXO01-20261024-r2, simulex-JOB-20261024). Plots and the report were drawn by Hexanta from values in the Simulex results files; screenshots are cropped and visually reviewed. Nothing was re-simulated. · Pack la-hotel-evacuation-r3 (built 2026-10-25); every file is checked against its SHA-256 before it is shown.
