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.
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
