From existing conditions to a model

We use photogrammetry and in-house software to create realistic models for FDS and Pathfinder from drawings or 360° video recordings. Site capture is quick and straightforward. After a short introduction, your consultancy can carry it out using its own camera or one supplied by us.

We agree model preparation, simulation and delivery to suit your project interfaces. The scope can range from a prepared base model to a complete simulation model. Model components and delivery formats are agreed before work begins.

Typical workflow

1. 360° video capture

   A high-resolution 360° camera is available for interiors. For outdoor scenarios and open areas, we use a drone with VR control and a 360° camera.

2. Photogrammetry and AI-assisted classification

   In-house software uses AI to classify, group and name walls, ceilings, floors, downstand beams and other components. During a virtual walkthrough with a VR headset, we check geometry and component assignments. We refine the model manually where required.

3. Simulation model

   Depending on your requirements, we add an optimised computational mesh, agreed design fires and project-specific analysis logic, including complex output requirements.

Model structure to suit the task

Depending on the task, models can use finely resolved individual blocks with realistic colours or larger, combined blocks to reduce computational resource requirements.
