PROJECT CLOSEOUT DOCUMENTATION AT JMC FABRICATION
A JMC Fabrication closeout package documents the finished work: drawings, material test reports, welder qualifications and procedures, weld logs, NDE reports, inspection records, and any project-specific certificates the spec calls out. The package scales with the project. A commercial duct job gets a leaner closeout than a NAVSEA spool fabrication or an oil & gas EPC handoff, but the structure is the same.
The goal isn't paperwork for its own sake. It's a closeout package the customer's QA team, an owner's rep, or a code inspector can pull a single weld out of and trace all the way back to the mill heat, the welder, and the inspector.

The worst time to define closeout requirements is the week before delivery. By then, decisions about what got stenciled, who signed which weld log, and whether NDE was witnessed have already happened. If the records weren't kept during fabrication, they can't be reconstructed after.
On JMC's projects, the documentation scope is part of the kickoff conversation. The customer's spec gets reviewed against JMC's standard closeout template, gaps get identified, and any additional records (witness inspections, PMI, special MTRs, custom traveler formats) get planned into the shop process before the first cut.
That front-loaded approach is why the closeout package can be assembled at the end without a scramble. Every weld log already has the welder ID, every cut piece already carries the heat number, every NDE inspection is already filed against the weld ID. Closeout is compilation, not detective work.
Every JMC closeout starts from a common backbone, then adds project-specific records based on the spec. The backbone includes shop drawings (as-built where revisions occurred), material test reports for every heat used, the welding procedures and welder qualification records that covered the work, weld logs tying each joint to its WPS and welder, visual inspection records on every weld, and the dimensional inspection records for the finished assemblies.
On top of that, the project-specific layer adds NDE reports (MT, PT, RT, UT) where the spec required them, third-party CWI sign-offs where applicable, PMI results on stainless and alloy work, nonconformance reports with their dispositions, repair WPS records where any repairs happened, and any project-specific certificates the contract demands.
The package gets indexed so a reviewer can find any single record in seconds. That indexing matters when the customer hands the package to their owner months later for an O&M review or to an insurance auditor after an incident.
Most JMC closeout packages follow the same section order, which makes review fast for customers who see a lot of fabricator packages. The typical layout:
- Cover and index: Project name, JMC job number, customer PO reference, scope summary, and a hyperlinked index of every section. The reviewer can find what they need without paging through hundreds of sheets.
- Shop drawings (as-built): Final shop drawings with any revisions reflected. Drawings are tied by part number to the rest of the documentation.
- Material documentation: MTRs for every heat used, with a heat-to-part cross-reference so a single piece on a drawing maps to a single MTR. Filler metal MTRs and certificates of conformance are in this section too.
- Welding procedures and qualifications: All WPS used on the job, supporting PQR records, and Welder Qualification Records (WQR) for every welder who touched the work. AWS, ASME, or NAVSEA references as applicable.
- Weld logs: Every weld on the assembly logged by weld ID, welder, WPS, date, and inspector. The weld log is the spine that the rest of the QC documentation hangs from.
- Inspection records: Visual inspection sign-offs, dimensional inspection results, and NDE reports (MT, PT, RT, UT) where the spec required them. Third-party CWI sign-offs are filed here when applicable.
- Nonconformance and repair records: Any NCRs raised during the job, their disposition, repair procedures used, and re-inspection results. Repairs aren't hidden; they're documented as part of the audit trail.
The closeout package isn't one size fits all. Here's roughly how the documentation depth scales across the project types JMC sees:
| Project Type | Typical Documentation Depth | Format |
|---|---|---|
| Commercial HVAC duct (SMACNA) | Drawings, basic mill certs, weld logs, visual inspection, leak test if specified | PDF closeout |
| Commercial structural steel | Drawings, MTRs, WPS/PQR/WQR, weld logs, VT, MT on tension splices where called out | PDF closeout |
| ASME B31.3 process piping | Full traceability, WPS/PQR/WQR, weld logs, NDE per spec percentage, pressure test records | PDF closeout, sometimes O&M binder |
| Marine (ABS) and oil & gas EPC | Full traceability, third-party witness records, full NDE, PMI, NCRs, pressure tests | O&M binder + PDF, indexed |
| NAVSEA (Navy work) | Navy tech pub references, witness inspections, full traceability with consumable tracking, all NDE and dimensional records | O&M binder + PDF, formatted to Navy submittal requirements |
Navy and marine projects push closeout further than commercial work. NAVSEA references its own tech pubs (S9074-AR-GIB-010/278, NAVSEA 0900-LP-001-7000) for the documentation format and the inspection records that have to be in the package. Witness inspections by Navy QA or prime contractor QA are signed in the records, not assumed.
Consumable tracking gets more detailed. Low-hydrogen electrode oven logs, dated handling records, and lot-level consumable traceability all sit in the closeout. PMI on critical alloy joints is standard. Repair tracking is detailed enough that an auditor can see the original indication, the repair WPS, the repair welder, and the re-NDE result in one place.
ABS-classed marine work follows a similar pattern with ABS rules in place of NAVSEA tech pubs. The substance is the same: deeper documentation, third-party witness, more rigorous closeout indexing.
Oil & gas EPC contracts flow down owner requirements to every subcontractor. For a fabrication shop, that usually means full traceability on every piece, NDE percentages set by ASME B31.3 fluid service category, pressure test records with calibrated gauge IDs, and a closeout format that matches the EPC's standard.
On larger refinery and petrochem projects, the EPC's QA team often wants a draft of the closeout structure before fabrication starts so they can confirm the format matches their owner's expectations. JMC will share a sample closeout from a comparable project at kickoff if that helps the EPC align early.
Pressure test records are a piece that catches some shops off guard. A spool fabrication isn't complete in the eyes of an EPC until hydro or pneumatic test results are part of the package, with the test pressure, hold time, gauge calibration, and witness sign-off all recorded.
Closeout isn't just compiled; it's reviewed and signed off before it leaves the shop. Depending on the project, sign-off includes:
- JMC QC manager: every closeout, internal sign-off that the package is complete and accurate
- Project manager: confirms scope completion against the PO and any change orders
- Customer QA representative: on marine, NAVSEA, and oil & gas EPC work, the customer's QA reviews and signs
- Third-party CWI or NDE technician: where third-party inspection was scoped, their sign-offs are in the inspection section
- AI (Authorized Inspector): on ASME-stamped pressure equipment work where an AI is part of the chain
- Owner's representative: on larger EPC and Navy work, the final review sometimes flows up to an owner's QA
Modern projects expect a searchable PDF closeout indexed with bookmarks. That's the default JMC produces. PDFs travel between the customer's PM, QA, engineering, and owner without copying issues, and they archive cleanly.
On larger marine and oil & gas projects, the contract sometimes also requires a physical O&M binder, organized by tab, with the same content as the PDF. The binder ends up in the customer's facility records or on the platform. JMC produces both formats when the contract requires it, off the same indexed source so the PDF and the binder match exactly.
Either format, the goal is the same: a customer reviewer can find any record about any weld or any part in the assembly within a minute, without having to call the shop. That's the standard JMC's closeout process is built against.
What's the difference between a basic and a full closeout package?
A basic closeout (typical on commercial duct or light structural) includes drawings, mill certs, weld logs, and visual inspection records. A full closeout (typical on code piping, marine, NAVSEA, and oil & gas EPC) adds heat-level traceability cross-references, WPS/PQR/WQR for every welder and procedure, NDE reports with witness sign-offs, PMI results on alloy work, pressure test records, and nonconformance/repair documentation. The scope gets set at kickoff so the records get kept along the way.
When should we tell JMC what closeout we need?
At kickoff, before the first cut. Closeout depth drives the shop process: which records get kept, which inspections get scheduled, what gets stenciled. If a customer asks for full traceability after fabrication has started without it scoped in, some records may not be reconstructable. Catching the requirement at kickoff is the difference between a smooth closeout and a scramble at delivery.
Does JMC produce closeout in our company's format?
If the customer has a required closeout format or template, JMC will produce to it. Many EPC and Navy customers have their own submittal structures. JMC's default format is a searchable, indexed PDF that satisfies most commercial and industrial customers, but the structure is adaptable to whatever the contract requires.
Are repairs included in the closeout, or hidden?
Repairs are documented as part of the audit trail. If a weld failed NDE, the indication, the repair WPS, the repair welder, and the re-inspection result all show up in the closeout. Repairs aren't a problem to hide; they're part of how a real QC system works. The customer can see the full history of every joint, including any that needed rework.
How long does it take to assemble a closeout after fabrication is finished?
It depends on project size and documentation depth. A commercial duct job's closeout can come out within a day or two of final inspection. A large marine or EPC project with full traceability, witness inspections, and PMI can take a week or more to compile, index, and review. JMC plans closeout assembly into the project schedule so the package is ready when the assemblies ship, not weeks after.
Will JMC keep a copy of the closeout after delivery?
Yes. JMC retains a copy of every closeout package internally for the project record. If the customer needs a reissue (lost copy, additional stakeholder requesting records, insurance audit), JMC can reproduce the package from the project file. Record retention follows JMC's QC policy and any contract-specific requirements.
What about pressure test records on pipe spool work?
Hydro or pneumatic test records are part of the closeout on any spool fabrication where pressure testing was scoped. The records include test medium, test pressure, hold time, gauge calibration data, witness sign-offs, and any incidents during the test. EPC oil & gas contracts almost always require these records; commercial piping sometimes does, sometimes doesn't, depending on the spec.
