Measure all painting, with the following exceptions, per foot super., and bill in yards. State that it includes cutting in edges, or measure this per foot run. Make the following additions to the figures in the Joiner's Bill:-
For work with exposed edges, add one-sixth. For square, framed, or moulded work with exposed edges add one-fourth. Twice the figures in Joiner's Bill for work painted both sides, such as doors, etc., unless there is a different description of painting to each side, in which case each must be taken separately. Keep iron and woodwork separate, and bill them under their several headings, as "Knot stop, prime and paint four oils on plain and moulded woodwork," or "Knot stop, prime and paint four oils, the last coat in parti-colours, on plain and moulded woodwork," or as the case may be.
Eaves gutter in and out, rainwater pipe, iron railings, giving height and description, skirtings, strings of stairs, skylight rail and bar, wood cornices and mouldings, etc., billing articles of similar size and description together. Architraves may be measured per foot run, or per foot super., the length by the girth; balusters per foot run, or numbered, and average length stated.
Rain-water heads, air gratings, etc. If painted both sides, state it. Keep separate two light and three light frames, and frames with tran-somes.
Door frames, counting two for one (one for outside and one for in).
Sash or casement frames, counting two for one (one for outside and one for in). Frames over 24 feet super. are called large; over 36 feet super., extra large.
Sash sheets (that is, each sash not divided by sash bars) counting two for one. Call those over 8 feet super, large; over 13 feet super., extra large. Sash squares, billed in dozens, counting two for one. Call those over 2 feet super., large. Number the sheets and squares of casements as to sashes, also number the opening casements for edges, or measure casement edge per foot run.
Number treads and risers of stairs both ends.
Number blacking stoves and ranges.
Painting may be taken at the same time the rest of the work is measured, the item for painting following each item to be painted, with a note of what additions are to be made, and if it is to be twiced. For example:-
2". 4 P.m. b. s. door
2/ + 1/4
The sign is always used to denote "four coats of oil colour."
The super. dimensions for painting are then abstracted into three columns, headed as follows:-
on Plain and Moulded Woodwork
Add 1/4 and 2ce.
Or, the painting may be abstracted direct from the Bill into their similar columns. This, however, can only be done when the painting is all of the same value. When there are two or more different descriptions of painting it is necessary to note it on the dimension sheets.
