Immutable Record

Built for Construction Compliance

An event-driven platform that captures decisions, approvals, and changes with cryptographic integrity-ready for any audit or dispute resolution.

Tamper-Evident

Every event is hash-chained to its predecessor. Any attempt to modify historical records breaks the chain and is immediately detectable.

Decision-Aware

Not just activity logs-BrieXO understands the semantic meaning of events: approvals, rejections, supersessions, and corrections.

Analytics-Ready

The same event stream powers both audit and analytics, ensuring your reports and dashboards always reflect the complete truth.

UK & EU compliance-ready by design

Audit Ledger keeps Golden Thread records, gateway submissions, and safety evidence aligned with UK Building Safety Act requirements and EU expectations for digital records.

Golden Thread evidence

Capture and verify every approval, change, and safety decision with immutable audit trails.

Gateway-ready submissions

Build compliant evidence packs for Gateway 2 and 3 without chasing files across systems.

Cross-region governance

Keep UK and EU portfolios aligned with consistent audit and reporting standards.

Cryptographic Integrity

Hash-Chained Audit Trail

Every event in BrieXO is cryptographically linked to its predecessor, creating an unbreakable chain of custody for all project decisions.

  • SHA-256 hash of each event includes parent hash
  • Modification attempts break chain integrity
  • Complete audit history with chain verification
  • Export audit trails for regulatory compliance
