c. Built-Up Sills. Joints are stagger where built-up sills are used. Notice in Figure 1-4 how the
built-up sill corner joints are made. Heavier sills are used if posts are used in the foundation. Sills are
single heavy timbers or built-up of two or more pieces of timber (see Figure 1-5, page 1-4). Where
heavy timbers are used, the joints should be placed over the post (see Figure 1-6, page 1-4).
