Evidence Architecture for Critical Infrastructure
External evidence architecture for hydrogen, water, energy, cooling and contractor-heavy operations – working alongside your existing advisors and vendors.
- No integration. No data access. No IT disruption. No new platform to buy.
- One high-risk flow at a time – hydrogen, water, energy, contractors.
- Audit-grade evidence chains in days, proven by your own teams and compatible with Big4 and integrator methodologies.
What we are
We design evidence architecture – not software.
RGRA is a neutral evidence layer that sits above your existing systems and processes.
We don’t touch your data. We don’t integrate.
We define how truth should flow: who did what, when, with which proof – so that hydrogen, water, energy and contractor flows can withstand auditors, regulators and boards.
How we work with your ecosystem
We enter as an external evidence architect, not as a competing vendor.
Our work sits above your existing systems, advisors and integrators – including Big4, boutiques and OEM partners.
They continue to own implementation, reporting and day-to-day operations. We own the design of the evidence chain that underpins their work.
This makes adoption low-friction and conflict-free: your partners keep their role, while your organisation gains a defensible, replayable chain of proof.
Why now
Hydrogen, water and grid projects are moving into multi-billion territory.
Audit, disclosure and ICFR expectations are rising every year.
Utilities and giga-projects are under pressure to prove how things work – not just what the dashboards show.
Evidence is no longer a nice-to-have. It is a core governance function.
Featured evidence domains
| Domain | Evidence chain | Typical pressure |
|---|---|---|
| Green Hydrogen | Production → storage → offtake | Certification, claims, reporting and assurance. |
| Water & Desalination | Abstraction → treatment → delivery → billing | Non-revenue water, leakage, billing integrity. |
| District Cooling | Capacity → flows → outages → customer impact | SLAs, penalties, outage traceability. |
| Contractors & Mega-Projects | Scopes → hand-offs → approvals → claims | Disputes, delays, variations and overruns. |
How it lands
One selected high-risk flow (green H₂, desalination, contractor hand-offs, outages).
A custom evidence chain: events, responsibilities, proofs, daily locking, audit replay.
A signed, audit-ready blueprint your teams can operate without any new software.
