Having measured all the common brickwork (except garden and fence walls, which may be conveniently measured all together as the last item under common brickwork), start with the chimney breasts, taking one at a time, following each up through the various floors and finishing with the stack, which latter is measured as solid, making no deduction for flues. Take no notice at this stage of any projections on stacks for caps, etc. Start with the extra digging, and follow the order of the list. Note that the extra width of trench, concrete footings, and damp course, and the extra thickness of breast, will all be the same, the lengths only varying with the spread of the foundations. Nearly the whole of the extra digging will be carted away, the portion filled in and rammed having previously been measured with the general walling, with the exception of the small portions above the concrete and footings at ends of breast, indicated by dotted lines on Fig. 24.
Take Rough Rendering outsides of flues against floors and roofs as they occur. These are numbered.
Battering Walls are kept separate. State the amount of batter. If one face only batters, measure as common brickwork, and take a super. dimension of extra for battering face, stating the batter. Include templates.
Measured per foot super., the length by the mean girth (see Fig. 25). State the thickness and bill as reduced brickwork in vaulting, and fully describe, - as, for example, "In two half-brick rings in cement."
Measure per foot super. and bill in squares. State that it includes horsing, and the height of same. If it is groined, keep it separate and state it, and measure the groin point per foot run as extra for groin point, including raking, cutting, and waste, and write this short in the Bill.
Brickwork in Backing to stone is kept separate, and cutting and bonding to stone included in the description.
Brickwork in Cement in Underpinning is kept separate, and described as in small quantities. State that it is to include any head pinning required, and all shoring.
Take Caulking in cement and sand (1 to 1), mixed stiff per foot run, and state thickness of wall. This is taken to the joint between the top of underpinning and the old wall. This is the practical way of carrying out the oft specified "wedging up in slates and cement," and makes a much sounder job.
Brickwork (usually in cement) in Filling up old Openings is kept separate, measured wide enough to allow for bonding, and described in small quantities. It should include cutting and bonding to old work in the description, or the cutting and bonding may be separately measured per foot run, and the thickness of wall stated.
Brickwork in Raising on old Wall should be kept separate.
Prepare Top of Old Wall to receive New, measured per foot run, and thickness of wall stated. If the top courses are taken down, include this in the description, stating how many courses.
Draw, Tooth, and Bond is measured per foot super. State that it includes extra materials.
End of New Wall cut and bonded to Old is measured per foot run. State the thickness of wall. The extra brickwork required for the bonding should be measured with the new walling.
Measured per foot super. as extra on common brickwork, commencing with the stacks, and completing them with their cappings, plinths, etc. Next measure the general facings to 3 inches below ground line, and allow 2 1/4 inches in the length for each internal angle for bonding. Take a wall at a time or collect, whichever is more convenient.
When it is intended to measure all extras under "Facings" as extras on common brickwork (and this is by far the better plan), much repetition may be saved by stating it in a note immediately under the heading in the Bill.
Measure the projections of cornices, etc., their length by the mean projection, as common brickwork, and deduct the facings behind them; then measure the cornices per foot run as extra on common brickwork, and fully describe, giving their height and projection. If in short lengths, state it. Number the mitres, fitted ends, mitred and returned ends, etc., which should be "written short" in the Bill.
Measure the projections as common brickwork, and deduct the facings behind them; then measure the oversailing courses per fool run as "extra on common brickwork," stating the number of courses in height, the total projection and if set back over, include "pointing to match facings." If any course consists of all headers, state it. Square angles may be included in the description.
Chimney Cappings may be numbered and fully described, stating the length and thickness of stack; and, as the work is in short lengths with many mitres, this method will perhaps convey to the Builder as good if not a better idea of its value than the more detailed one.
