What about structural sizes?

The floor systems are specified as 2×10 #2 syp. or floor trusses (sized by supplier). The cover sheet supplies span charts for floor joist, ceiling joist, and roof rafters in both #2 southern yellow pine and #2 spruce-pine-fir. All beams that accumulate loads from the roof structure must be sized locally, as the snow loading requirements are regional. Beams are called out as “LVL”, which means “laminated veneer lumber”. These members can be sized by the local supplier for free; this is routinely done.
