- Shorten trusses 5/8" @ angled walls so outside of ribbon board is flush with stud line.
- Send out a detailed floor truss layout.
- All trusses have a black up arrow that corresponds with the truss layout specifying which end of the truss goes to which side of building.

- Line up floor webs for plumbing & heating.
- Watch for mechanical issues to make sure areas can get heating/cooling ducts.
- Locate plumbing drains on truss layout to prevent plumbers from cutting, notching or drilling thru trusses. Framers can shift trusses and/or add extra truss where needed.

- Figure girder to carry flush beam to open up railings @ stairway.
- Review stairwell openings for proper headroom to make sure the proper number of risers is figured.
