Miscellaneous Rules for Brickwork

As before stated, the labor and material for brickwork are estimated by the 1,000 brick. In measuring up brick walls it is not customary to deduct for openings. To ascertain the number of bricks in a wall: first obtain the number of superficial feet, and multiply this by seven for a 4-inch wall-by 14 for a 9-inch wall-21 for a 13-inch wall-and 28 for a 16-inch wall.

If thicker than 16 inches, for each additional 4 inches in thickness add 7 bricks per square foot. One thousand five hundred brick is an average day\'s work for outside and inside walls, and we take three-quarters of a barrel of lime and 8 bushels of sand to make the mortar. The number of brick a mason will lay in a day on a plain wall depends largely upon its thickness.

On 8-inch work, 1,200 to 1,400; on 12-inch work, 1,500 to 2,000; and on 16-inch work 200 to 2,500; veneered work or single-back walls attached to wood-work is much blower, from 400 to 600 brick is regarded a day\'s work; this includes tying the brick with nails to the framework, or sheathing.

A perch is 16 ½ feet long, 1 ½ feet wide, and 1 foot high, and contains 24 ¼ cubic feet. In estimates, 25 cubic feet is figured as a perch. A perch in the wall contains about 22 cubic feet of stone and three cubic feet of mortar. The waste, ordinarily allowed in laying stone walls from the rock measurement, is 1/5. A cubic yard rubble masonry laid in the wall contains 1-1 ½ cubic yards of undressed stone and ¼ of a cubic yard of mortar.

Four perches, or 100 cubic feet of wall, will contain ordinarily 1 cord of stone or 128 cubic feet, 1 barrel of lime, or say, 2 ½ bushels, and 5 barrels of sand. A day\'s work for a mason\'s helper is moving 4 to 5 perches of stone and mixing and carrying to the mason sufficient mortar to lay them. A man will lay in one day from 4 to 5 perches of rubble masonry in sandstone, or 3 perches in limestone.

If thicker than 16 inches, for each additional 4 inches add 7 bricks per square foot. One thousand five hundred brick is an average day\'s work for outside and inside walls, and we take 3/4 of a barrel of lime and 8 bushels of sand to make the mortar.
