Turnover packages rarely fail because the work was bad.

They fail because two documents disagree — and nobody compared them until the client did.

Six that come up again and again.

A weld in steel and not on paper.

The isometric shows 47 welds. The log has 46.

Somewhere out there is a joint that was welded, probably examined, and never recorded. Finding which one means walking the line with a print.

Continuity that lapsed mid-job.

A welder is current on day one. Their continuity lapses in week four. They keep welding.

Every weld after that date is unqualified. The fix isn’t paperwork — it’s cutting them out, after the system is tested and painted.

A heat number with no MTR.

The material may be perfectly sound.

Without the certificate it is untraceable — and untraceable material is non-compliant material. The vendor moved on months ago.

A calibration that expired before it was used.

The gauge on the pressure test had a certificate. It ran out eleven days before the test.

The test is unverifiable and has to be repeated — on an insulated, painted, energised system.

An NCR nobody closed.

Raised in week two, dispositioned verbally, worked off in the field, never written up.

One open nonconformance holds the entire package, however complete everything else is. It is almost always the earliest one.

An as-built that contradicts the log.

A joint gets relocated in the field. It is redlined on the drawing, correctly. The weld log still shows the original.

Both documents are honest, and they disagree. From the outside that is indistinguishable from a records failure.

None of these are quality problems.

The welds are sound. The material is right. The tests passed.

They are consistency problems — and not one of them is visible inside any single document. That is why the client finds them and the contractor doesn’t.
