Fragility.
How every asset actually responds.
Not one generic curve per occupancy class — a defensible β for each asset, built on 15 years of designing structures that cannot fail. Buy exactly the certainty the exposure justifies.
Four grades of β. Buy exactly the certainty you need.
Each grade adds a defined layer of building-specific evidence and earns a tighter, fully-sourced β. Mix grades across a portfolio — triage the long tail cheaply, spend engineering only where the exposure justifies it.
Catalogue
Location + occupancy. Regional archetype prior. No imagery, no visit.
Visual AI
Façade & overhead imagery. Structural system, height, irregularity, soft-storey flags.
Walk-down
On-site rapid survey. Drawings & retrofit evidence, captured and structured.
Analytical · PBSD
Full drawings + material data. Nonlinear performance-based model. Asset-specific, verified.
β ≥ 0.30 is physics, not a sales floor. The record-to-record variability of ground motion is irreducible. We engineer β down to that floor and then tell you we've stopped — that honesty is the moat.
Built on structures that cannot fail.
“Fragility curves today are built on simplified assumptions. Ours are built on 15 years of designing structures that cannot fail. By embedding performance-based seismic design into AI-driven models, we transform fragility from generic to engineering-grade.”
Vera turns evidence into β.
Vera is the assistant that runs the upper grades: she knows what each structural family needs to climb a grade, drives the data collection, and reconciles every number back to the evidence that produced it.
- Visual AIFamily-specific checklist, classification, gaps flagged.
- Walk-downOn-site protocol issued, findings captured into the dossier.
- PBSDAnalytical fragility cross-checked, β sealed with its provenance.
Fragility is the vulnerability layer.
Combine it with Sismicus hazard, and Risco turns both into loss and pricing.
