Measure per foot super. to all plain surfaces exposed to view, and the kind of finish stated in the description. Plain work under 3 inches wide is measured per foot run and the width stated. If stopped, keep it separate.
Sunk Work or Sunk Face is plain face worked below the original face of the stone, and is measured per foot super. if over 3 inches wide or girth, and per foot run if less, stating the width or girth and the kind of sinking, as rebate, groove, etc. If stopped, keep it separate.
Number and describe and state girth.
Rough Sunk Work, measured per foot super., is taken in addition to any labour of greater value than bed or joint which has to be finished 3 inches or more below the original surface of the cube. For example (see Fig. 27), if the distance DB is 3 inches or more, rough sunk work must be measured, but the dimension for this will vary according as the distance EC is or is not less than 3 inches. If EC be less than 3 inches the dimension will be the length of the stone by the width AB. If EC be 3 inches or more the dimension will be the length of the stone by the girth AC and CB.
Measure per foot super., the length by the girth of the moulding, if over 6 inches girth. Measure per foot run, and state the girth if 6 inches girth or less. In measuring mouldings, take their length along the extreme projection.
Mitres are numbered and the girth stated.
Where the moulding is measured per foot run the mitres may be written short.*
Number and describe and state the girth. These may be written short where the moulding is taken per foot run.
Circular Moulded Face is measured as described to "moulded face," also its mitres and stops.
Measure per foot super. to plain convex surfaces. If stopped, keep it separate.
Measured as to sunk work.
Measure per foot super. to all concave surfaces; also to such work as the shafts of diminishing columns. If with "entasis," state it. If stopped, state it.
Mitres and Stops as described to Sunk work.
Measure per foot super.
* The term "Written short" is applied where mitres and other numbered labours directly follow the lineal dimension of the item to which they apply, the figures being written in the Description Column so as not to interrupt the usual order in the Bill, as, for example:-
Moulding 4" girth. No. 8 mitres. No. 2 mitred and returned ends.
to the convex surfaces of work circular in all directions, such as spheres and domes. If stopped, keep it separate.
Circular Circular Work Sunk per foot super. to the concave surfaces of work circular in all directions, such as to niche heads, etc. If stopped, keep it separate.
Number and describe.
Balusters, Finials, and similar items are best numbered and sketched, including stone and labour; or the stone may be measured per foot cube, and the labour item numbered.
Bosting is the labour of roughly bringing the stone to the shape required for the carver, and is measured per foot super., or if a small item is numbered.
A sum is usually provided for this. Carving of an ordinary kind is often done by the builder, and in this case the items should be numbered and a sketch given, and the "bosting" may be included and the fact stated.
Tracery Heads, when they are not taken off in detail, should be measured per foot cube as stone, and all labour, and very fully described, including joints and slate dowels, mortices, etc., and a sketch of window given. Keep the arch stones with stoolings for tracery worked on separate. State in the description that it includes all strutting and ribbing.
This may be measured in detail as previously described, but it is more usual to measure it as stone and labour per foot super., stating the average thickness and fully describing it, giving the heights or average height of the courses, the dimensions of the bond stones, and how many to the yard super.
Filling-in to Groined Roofs is usually measured as stone and labour per foot super., and fully described. State that it includes all cutting and fitting to stone ribs, also the requisite centering, and that it is measured nett.
The ordinary items of stonework, such as steps, thresholds, hearths, window-sills and heads, copings, etc., whether in Portland, York, or any other stone, when used in a brick building or not in conjunction with other stonework, are usually measured as stone and labour per foot run, and fully described; and only the extra labours upon them are separately measured, such as "sunk joints," "fair ends," "mitres," "mitred and returned ends," etc. These are usually "written short." Some of these have already been dealt with in their order under the heading of "Openings." In the case of gable copings, the kneelers, bonds, stones and apex stones are numbered and described, and their dimensions stated. Give sketches if necessary.
Stone Staircases are rarely measured in detail. The usual method is to number the steps and fully describe them, giving their dimensions.
Number the winders, and describe as above. State if soffits are flueing.
Keep steps with curtail ends separate, and fully describe.
Number the mortices for balusters, etc.
Number the ends cut and pinned or built in, and bill in Bricklayer.
Landings, per foot super. State thickness, and describe.
Joggle Joint and Back Joint per foot run.
Edge Cut and Pinned per foot run; billed in Bricklayer. Any labour to edge per foot run.
Templates, Base Stones, Corbels, etc., are numbered, and described as stone and labour.
