Measure per foot super., and bill in yards, and describe as "Lath plaster, float, and set ceilings," or as the case may be. The same dimension answers for whitening or distempering. If ceiling be panelled, state it, and give the size or average size of the panels. If between wood ribs, state it, and that it includes fitting to ribs; or a better way is to measure the labour fitting against wood or stone per foot run. This is measured wherever the plaster stops against wood or stone. Keep sloping ceilings separate. Keep curved ceilings separate, and state the radius.
Counterlathing per foot super. If in narrow widths, keep separate.
Deduct these as they occur, as for stairs, etc.
Include "setting out" in the description, or take a numbered item for "setting out to geometrical pattern," giving the dimensions of the ceiling.
Number. Keep irregular ditto. separate.
Bracketing per foot super. the length by the girth, and state thickness. Number the angle brackets as "Extra for," and measure fillet for fixing brackets to, per foot run; or,
Measure the bracketing per foot run, giving the girth of cornice. State the thickness, and include the fillet. Number the angle brackets, and write them short in the Bill.
Measure per foot run up to and including 12 inches girth, and per foot super. over this. State if they include "dubbing out." If they are on bracketing, state that they are "on and including lathing."
Measure per foot run, and describe.
Mitres, etc., as to mouldings.
A small cove, if part of a cornice, would be measured as such; otherwise measure per foot super., the length by the girth.
Mitres, etc., as to cornices.
No notice is taken of short lengths of cornice where they occur in the ordinary way in a room, as to chimney breasts, etc., but where there are an unusual number they should be kept separate.
The dimensions for cornices, coves, etc. will also answer for whitening or distempering. State what it is to, or it may be included in the description of cornices, etc.
Measure per foot super., bill in yards and describe as "render and set," or "render, float and set," etc., as the case may be. The same dimension serves for distemper, paper, etc. Keep narrow widths as to reveals, etc., separate, and bill in feet. Reveals not exceeding 9 inches wide are measured per foot run.
Measure per foot run. If with a reveal not exceeding 9 inches, measure and describe the two together as "arris and 6 inches return," or as the case may be.
Measure per foot run, and state widths of wings or returns, as "Keene's cement angle and two 1-inch returns on Portland cement grounds." A portion of this description is, however, usually saved, as this item would be under a heading of "Keene's cement," which might have the following note attached: "All Keene's cement to be on Portland cement grounds."
Measure per foot run, stating girth.
Number the mitres, and number and describe the stops, whether plain, moulded, etc.
Lath plaster and set; lath plaster, float, and set, etc. - Measure per foot super., and bill in yards. The remarks under Walls will apply here, with the altered description; and the arrises, angles, etc., will be measured as just described. Take counter-lathing as it occurs. If in narrow widths, keep separate and bill in feet super.
