Saw a crazy expansion joint detail at the new library downtown
They used a full 2-inch foam strip with a custom metal cap, and the foreman said it's for a 3-inch seasonal shift. Anyone ever spec something that wide for a public slab?

Worked on a museum project with a 4-inch joint once. The whole floor was this giant polished concrete slab. We used a heavy duty neoprene insert with a bronze cover plate. Key was letting the filler COMPRESS a full 50% without buckling. That metal cap they used is probably for the same reason, to handle the squeeze without looking bad. Big public spaces move a lot, you gotta plan for the full range.

Wow, 3 inches? I mean, @iris574's museum story is wild but that feels like overkill for a library. Maybe it's just me but that's a lot of movement.
