Work inside a boundary dated after the test that covers it
Weld 1147 was cut out three days after its turnover package test was signed
Train 3 of the gas plant has 41 days to first gas, and hundreds of binders read complete in the same fortnight. On this morning the seal gas binder for one compressor stops being taken on trust.
demoPlant, contractor, crew and counts in this walk-through are sample data.

364 subsystems show 100%, and in 23 the records don't add up
Binder reader and calendar builderThe completion tree draws the train as 14 systems and 638 subsystems. Overnight the agents read the 364 unsigned binders that show 100%, none sampled: 109,553 records on 453,803 pages. They left 27 flags in 23 subsystems: 22 wait for the completions engineer, 3 for a ruling, and 2 are already held.

158 of 158 check sheets signed, and in filing order nothing looks wrong
Completions engineerSubsystem 31-04 feeds seal gas to Compressor A. Its binder is 1,412 pages and 344 records, all sheets signed, so the completions system calls it complete. Laid out as filed, each record sits at its page and the dots read like any clean binder. The engineer sees the flag only because the agents read every page, not a sample.

On one calendar the test sits three days before the weld it covers was redone
Completions engineerOne click lays every dated record on one line. Pressure test HTP-31-0412 was signed, a film audit then rejected weld 1147, and the weld was cut out and rewelded three days after the test. The repair page says it plainly: no later pressure test is named on this record. Both records are signed and correct alone. Together they leave a gap.

The agent is 97% sure, and says the ruling is not its call
Completions engineerThe two pages open side by side: the test boundary covers welds 1139 to 1152 at 2,160 psig, and the repair record puts weld 1147 inside it. The date tester states what it found and hands the question to the QA/QC lead. Below sit what stands on this test: the reinstatement check, the nitrogen blow, and the compressor taking gas on recycle.

He proposes a hold with a reason, and cannot sign it himself
Completions engineerThe engineer has opened both records, so the proposal is open to him. He picks the reason that fits what the pages show: the repair is inside the test boundary, so a retest is owed. A note is optional and he leaves it. The proposal goes to the QA/QC lead, because the person who proposes a hold may not be the one who signs it.

The QA/QC lead opens both pages herself, then signs the hold
QA/QC leadShe does not rule from the proposal. She opens the test record and the repair record, and only then can she rule. Her ruling is that this test no longer proves the weld. Mechanical completion for 31-04 cannot be signed, and commissioning cannot take it, until it is released after a retest or lifted by two people who open the records.

The retest goes to the contractor as an item, after her signature
Item writerItem RX-0412 asks the contractor to pressure test the boundary again after the repair of weld 1147, then redo the steps that followed the old test. It was drafted after the ruling and sent on her signature. The contractor's coordinator sees only their own items and answers there, so the request is dated and tracked instead of living in an email thread.

Three subsystems are stopped by a hold, and he can see which
Commissioning managerSystems are listed by the date they take gas, each with its sign-by date and where its binders stand. A band across the top names the three subsystems a hold stops, what each one feeds, and whether the contractor has booked a retest. For 31-04 that is Compressor 210-C-3101 on recycle, with no retest date yet. He knows what he cannot touch.

Seven entries show who opened which record, minute by minute
Internal auditorFiltered to people, the audit trail reads the morning in order: the engineer opened the repair, the test and the repair again, then proposed; the QA/QC lead opened the test at 08:20 and the repair at 08:23, and signed at 08:29. The hold also wrote a category A punch item. Nothing here can be edited, and the evidence downloads with it.
