Which plan indicates the size and spacing of structural lumber including trusses?

• A. Framing plan
• B. Elevation plan
• C. Site plan
• D. Foundation plan

Answer: (A)

The framing plan is the one that shows the size and spacing of structural lumber including trusses. It lays out where every structural member goes, specifies their dimensions (like stud, joist, beam sizes), and the spacing between them and the trusses. This information is what builders use to order lumber, cut pieces to length, and assemble the frame so loads transfer correctly. Elevation plans concern vertical faces, heights, and finishes; site plans show the building’s placement on the lot; foundation plans detail footings and concrete walls. Because the framing plan conveys the exact layout, sizes, and spacing of the structural members that form the building’s skeleton, it’s the plan that communicates the lumber and truss details.
