Revit
Structural Framing category; beams, braces and joists share it

LITHIC category
structural framing
Quantity basis
Length (m) with a governed profile; mass (kg) where the profile declares it
Classification placement
Where this element is normally designated in each Swedish reference system. Code values stay with their publishers.
| System | Designated in | What it establishes |
|---|---|---|
| CoClass | Functional systems (carrying), then Components | The framing system carries; the beam is the component within it. |
| BIP | Object designation carrying the profile and steel grade | Makes profile and grade readable without opening the analysis model. |
| BK04 | Group and article — profiles, connections, coatings | Supply grouping; connections are separate articles. |
Where it enters the chain
Identity → classification → contract → recipe → product → cost → carbon. Steel mass is the dominant carbon driver here.
What a code lookup does not settle
- Connections, plates and bolts are rarely modelled and must be declared by a recipe.
- Beams and braces sharing one Revit category does not make them one population.
