Defining Responsibilities for CFS Truss Submittals
Define who supplies, designs, coordinates, and reviews CFS truss layouts, reactions, connections, and bracing before fabrication.
The condition to resolve
A supplier can submit truss designs while the building team assumes the package also addresses roof diaphragms, supporting walls, and every field connection. Those assumptions create scope gaps. Establish the documents and interfaces each party must provide before accepting a submittal as ready for production on a US construction project.
Coordinate before releasing the work
Build a responsibility schedule for truss geometry, reactions, bearing connections, permanent bracing, temporary erection planning, and roof attachments. Ask the building designer to confirm the support and load criteria used by the supplier. Track review comments to closure and distinguish an accepted component design from a released building interface.
How it fits the building system
Cold-formed steel trusses are engineered assemblies, not a collection of interchangeable studs. Their geometry, connections, bearing locations, and restraint requirements belong to a coordinated design package. The truss supplier's documents and the building structural documents must address the same supports and loads. Establish who checks those interfaces and who resolves a conflict before fabrication or installation begins.
Keep erection conditions separate from the completed roof condition. Review handling, temporary stability, permanent bracing, and access with the parties assigned to each task. Installing roof panels does not by itself document that every required restraint or connection is complete. Preserve the approved layout and connection information in the field, and route unexpected conditions through a recorded review instead of cutting, splicing, or straightening a truss.

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.
- Assign geometry, reaction, connection, and bracing review separately.
- Confirm building load and support criteria with the truss supplier.
- Close interface comments before authorizing fabrication.
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 |
|---|---|---|
| Component design | Truss design package | Supplier design boundary |
| Building interface | Support and roof review | Compatible reactions and attachments |
| Erection | Assigned installation plan | Temporary-work responsibility |
Verification and handoff to the next trade
Before issuing the fabrication authorization, cross-reference the accepted truss layout with bearing locations and the current roof plan. Identify details that remain outside the supplier's scope and verify that another assigned party has completed them. The installation team should receive a coherent package rather than separate accepted sheets with conflicting assumptions. Preserve the responsibility schedule and final review responses so a later roof change can reach every reviewer whose interface is affected.
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 a truss supplier automatically design the whole roof?
No. The agreed scope defines responsibility. Explicitly coordinate diaphragms, supports, attachments, and bracing so accepted truss designs do not leave building interfaces unresolved.
Who releases the package for fabrication?
Use the project's documented review and release process. The release should confirm accepted design inputs and completed interfaces, not simply acknowledge receipt of the supplier's documents.

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.
