01 / Provenance
Source-linked
Scenario claims, detector data and assumptions retain document, page, revision and extraction confidence.
No orphan assertionsEvidence and assurance
A verdict is useful only if another engineer can reconstruct it.
Barrier Intelligence preserves the route from safety-study claim to physical detector vote, including every source, assumption, method, limitation and review decision in between.
Evidence model
Every state says what happened, why and how certain we are.
A compact verdict never replaces the engineering record behind it.
02 / Response
Physics-bound
Native plume, concentration, obscuration and timing metrics remain attached to the detector vote.
No score substitution
03 / Authority
Review-controlled
Conflicts, limitations, overrides and sign-off decisions are explicit parts of the final package.
No hidden judgementStandards alignment
Organised around the engineering practices your reviewers already recognise.
Barrier Intelligence supports the work of qualified engineers; it does not claim certification or replace their authority.
Performance-based F&G design
Connect hazard scenarios, detector performance and achieved coverage in a reviewable basis.
Fire and gas system application
Structure the evidence around hazard detection objectives, layout and operational context.
Safety lifecycle governance
Preserve traceability, assumptions, verification evidence and accountable approval.
Detector layout practice
Support rigorous layout assessment while retaining project-specific criteria and limitations.
The assurance package
Designed to move from technical review to action.
The deliverable separates evidence, finding, consequence and remediation.
Barrier Credit Register
A scenario-level ledger of claims, physical votes, evidence quality and final disposition.

Executive finding, method statement, limitations, remediation and qualified-engineer approval.
Act and signGovernance by design
Deterministic where reproducibility matters. Human where judgement matters.
The analysis can be rerun from the retained inputs and configurations without requiring cloud access to plant data.
Offline-capable
Assure3D can run without operational-technology integration or external model calls.
Configuration retained
Inputs, solver settings, evidence mappings and revisions travel with the result.
Engineer-authorised
The final claim, caveats and remediation remain under qualified professional control.
