The Audit Trail Nobody Wants to Need

This one isn't written for the inspector holding the film. It's written for whoever sits above them — the owner's NDT oversight function, or the third-party auditor (often a CWB Level 3 Inspector) engaged to review a contractor shop's procedures, methods, and personnel against CAN/CGSB-48.9712 and CSA Z662.

That job is fundamentally a sampling problem. A pipeline owner or its CER-facing compliance team can't re-read every radiograph a contractor shop produces across a project — there's too much volume. So the audit function samples: pull a subset of reads, check the procedure was followed, check the certified reader signed correctly, check the record is complete. The quality of that audit depends entirely on how good the underlying records are, and today those records are usually a shop's own paper or PDF reporting, produced by the same people being audited.

Here's the uncomfortable version of that setup: the audit trail you'd most want to exist is the one you only find out you're missing after an incident, when CER or a provincial regulator is asking for it and "we trust our contractor's process" isn't a complete answer.

An AI second read changes what the auditor is sampling against. Instead of auditing a contractor's self-reported reads in isolation, there's now a structured, timestamped, independent second opinion attached to every film — logged the moment the image was reviewed, not reconstructed after the fact. That doesn't replace the CWB audit function. It gives it something better to sample: a much larger, consistent base of documented reads instead of a thin slice of manually pulled files.

For an owner's oversight team, that's a smaller sample-to-confidence ratio — you can audit less and trust more, because the underlying record is stronger by default. For a third-party audit house, it's a faster engagement: less time reconstructing what happened, more time on the procedures and personnel questions that actually require a Level 3's judgment.


Where this goes next: this is usually the highest-leverage conversation for the workflow-automation side of the business. Audit houses and owner oversight teams aren't asking for a better weld reader — they're asking for a better system of record. Enrisk builds that system directly: intake pipelines from contractor shops, structured audit-ready packages, and reporting that's built for CWB and CER review from day one, not retrofitted onto it.
