That's right, Michael. You have to scarf the plate sections together if the building is too long for your timber.

As for sequence, sometimes you raise walls first w/ the top plate on and sometimes you raise bents first.

If the tie sits on top of the plate, you would raise walls and set the ties/trusses on top.

If you have a dropped tie (a tie that tenons into the posts below the plate), you would raise an "H bent" -- the posts and tie beam.

And if you have 2 stories, even if you have a tie above plate, you usually raise H bents with the posts and the floor beam -- then plates then ties.

Hope this helps
