### The structural design gap, the building's Seismic Design Category, the calculated thermal movement, and the required fire-resistance rating of each penetrated assembly are inputs to this standard; the cover assembly, filler, and fire barrier are sized and selected to satisfy them. {note}
−## Cover assemblies and fillers shall be provided at every structural expansion and seismic separation joint indicated, in the installation plane shown, sized for the movement demands established by the structural design. {note}
+## Cover assemblies and fillers shall be provided at every structural expansion and seismic separation joint indicated, in the installation plane shown, sized for the movement demands established by the structural design.
### Cover assemblies, fillers, and fire-barrier systems shall be furnished and installed at each expansion joint location shown on the structural and architectural drawings.

## Fire barrier and cover assembly coordination. {note}
−### The fire barrier and the cover assembly are a paired system: the barrier maintains the rating while the cover provides the finished, trafficked, or weather surface above it. They shall be furnished as a coordinated assembly so that the barrier's movement capacity and the cover's travel range agree. {note}

### The fire-barrier system and the cover assembly at a rated joint shall be furnished as a coordinated set with matching movement capacity.
