Planning & documentation
Releasing a CFS Fabrication Model to the Panel Shop
Build a documented CFS model-release workflow linking approved details, survey inputs, fabrication files, and unresolved coordination issues.
The condition to resolve
A coordinated building model can still contain dimensions copied from an outdated opening schedule or nominal slab geometry. Machine-ready data adds another translation step between design and fabricated parts. Treat release as a documented check of those inputs, not as a visual approval of a complete-looking three-dimensional model.
Coordinate before releasing the work
List the drawing, survey, product, and opening revisions used to create the fabrication model. Check sampled panel marks against their corresponding details and identify connections represented only in separate sheets. Resolve clashes by responsibility, then record any area held from production. Archive the released model identifier with the shop files so future changes can be traced.
How it fits the building system
Offsite panelization changes when coordination decisions become expensive to reverse. The fabrication release should connect an approved drawing revision to actual member data, panel geometry, and the field installation plan. A model that displays a complete wall may omit a connection, a finish clearance, or a delivery constraint. Review what the fabrication model contains and which details remain in separate documents.
Separate the permanent building design from temporary handling and installation planning. A completed wall panel is not automatically designed for every lifting, storage, or erection condition. Assign review of those conditions to the appropriate competent parties and keep the approved plan with the shipment. The field crew needs identifiable panels, an installation sequence, accessible connections, and a way to report damage without improvising a repair.

Practical location-based review
Assign an owner, location, and response document to each check. Include affected trades before fabrication or concealment; final dimensions and connections belong in the approved project documents.
- Record model, drawing, survey, and opening-schedule revisions together.
- Check a sample of panel marks against approved connection details.
- Identify held zones before exporting fabrication files.
Documents and decisions that must agree
Keep this comparison beside the current drawing. Record discrepancies as specific questions and preserve the response in that area's records.
| Item | Evidence needed | Decision to confirm |
|---|---|---|
| Model geometry | Approved input register | Current dimensions |
| Connection information | Detail-to-panel cross-reference | Complete fabrication instructions |
| Export | Release identifier and archive | Authorized production version |
Verification and handoff to the next trade
After release, verify a representative fabrication output against the authorized panel drawing and source product schedule. Record discrepancies at the translation step where they arose rather than editing only the final machine file. Reconcile held areas and withdrawn versions before another production export. Keep a recoverable archive of accepted inputs and output identities so the team can trace a physical panel back to the precise release used to produce it.
Give the next trade the current detail, the restrictions it must preserve, and open observations. Verify the installed work before concealment and retain an identifiable location in the final record.
Common questions
Does clash-free mean ready for fabrication?
No. A clash review addresses selected geometric conflicts. It does not establish product approval, structural review, surveyed dimensions, or completeness of fabrication instructions.
What should an approval record identify?
Identify the version, release area, approved inputs, outstanding exceptions, and approving responsibilities. A dated screenshot alone cannot establish which production files were authorized.

Prepare a supply inquiry
- Record the project drawing or detail and the specified product, profile, or system.
- List the complete configuration, physical units, quantities, and cuts per piece.
- Request current manufacturer documents; confirm compatibility, price, and availability before ordering.
- Obtain the responsible professional's review for loads, code requirements, or installation.
