Wall-Plates as previously directed, and all billed together.

Rough Oversailing For Wall-Plates

The projection is measured per foot super., the length by the height and the projection or average projection stated, and added to the common brickwork, and the labour measured per foot run as " Labour to rough oversail, or set back one course." Thus in a two-course over-sailing, such as is usually required for a wall-plate, there will be two courses oversailed and one set back.

The following are the dimensions as they would appear for 10 feet run of two oversailing courses of 4 1/2 inches extreme projection, and set back over as Fig. 28:-

1/2 B.


2 3/4 B. 3/8 B. in M.


Average 3/8 B.



Labour to rough oversail, or set back one course.

Roof Timbers

Bill per foot cube as "Fir framed in roofs." It will probably be convenient to measure these per foot run, and cube on the Abstract as described to Floor Timbers. Keep trusses separate, and bill as "Fir framed in roof trusses."

Remember that in carpentry all lengths must be measured from the extreme ends of tenons.
