A score is only worth
what stops us selling it.
The Threat Impact Assessment Bureau assesses physical threat exposure at properties, issues the TIA Score, and maintains the Threat Impact Model that produces it. It operates under a boundary we publish and do not cross — because a number a carrier or a lender is asked to rely on is worth exactly as much as the constraints on the party issuing it.
What the Bureau is — and what it is not
Created and maintained by AIA Innovations. Not a separate legal person, and we do not claim otherwise — that is a misrepresentation a counterparty could discover in ten minutes. Structural separation can follow if a counterparty requires it; the boundary below is built so that step is a formality rather than a rebuild.
An authority is conferred, and nobody has conferred one here. “Bureau” claims a function rather than a standing — true today, and the convention among private assessment bodies. We would rather be referenced for what we do than assert a standing the first serious question would puncture.
The score is the TIA Score
It was the AIA Score. “AIA” is the American Institute of Architects to most of the property, real estate, and construction market this sells into — a name the score would spend its life fighting for recognition against. The score moved to TIA; AIA stays the company.
| Thing | Name | Short form |
|---|---|---|
| The division | Threat Impact Assessment Bureau | TIAB, “the Bureau” |
| The score | Threat Impact Assessment Score | TIA Score |
| The model | Threat Impact Model | TIM, versioned — TIM v1.0 |
| The place index | Hyper-Local Integrated Risk & Resilience Index | HL-IRRI v0.1 |
| The coupling index | Systemic Entanglement Index | SEI v0.1 |
| The orbital fabric | OCML 6GL / G4 spacetime fabric | OCML v0.1 · generation 6 |
Scores issued before the rename are the same score under the same model. A report or credential referring to an AIA Score refers to this one.
Each one is a page, not a sentence
Independence
The Bureau assesses. It does not fix what it assesses, and it is never paid more for a better score. The boundary is published, and every element of it is checkable from outside.
Read the boundary →Methodology
Six weighted layers, published in full — what each measures, what it is worth, how sector profiles shift the weighting, and how a score reports the confidence behind it.
See how a score is built →HL-IRRI
Village-scale place risk: threat × (1 − resilience) on an H3 grid, with vertical sub-indices and Merkle ticks. Analysis index — not a TIA Score replacement.
Read the place index →SEI
Coupling of physical, financial, and aggregate behavioural layers. Entanglement, a stylised cascade, and named analogues. Analysis index — never self-executes.
Read the entanglement index →OCML 6GL / G4
Sixth-generation space-traffic language on the Implicit H3 Field. Intent compiles to G4 curvature, SDS OSM/CDM, ISO 8601 binding, five-year disposal.
Open the orbital fabric →Model versions
Every score records the model version that produced it. Changes ship as new versions with an effective date and a changelog. TIM v1.0 is in force.
Read the version history →Right of appeal
An assessed party may challenge any score within 30 days, reviewed by someone other than the assessor of record. Outcomes and reasons are recorded.
How an appeal works →We cannot both fix and score
Properties still need the work done, and AIA should still earn from it — just never on the properties it scores. The certified operator network is the answer: AIA certifies operators, certified operators perform remediation as independent third parties, and AIA earns certification and renewal fees. The Bureau never touches the work.
This is why the certification ladder exists at all. Every property that needs remediation raises demand for certified operators, and every certified operator is a route to another assessment.
- Designs, specifies, procures, or installs security measures at a scored property
- Recommends a named vendor, product, or installer for one
- Takes compensation contingent on a score or a score change
- Takes compensation from a carrier, broker, or MGA on a scored property
- Scores a property AIA or a principal holds an interest in
Have a property assessed
A published fixed fee, a field assessment against the model, and a report that states its own confidence — plus the 30-day right to challenge what it says.
