Brickwork is usually estimated by the thousand bricks, but is sometimes priced by the cubic foot at 40 cubic feet to a thousand. A mason in one day will lay from 800 to 1,000 common bricks, or 300 to 400 face bricks.

The number of bricks in a wall may be found by multiplying the superficial area by 7 1/2 for each 4 inches of the thickness of the wall. Openings of the size of ordinary windows are generally deducted, but very small openings will cost more to make than the deduction. An allowance for breakage should be made of 5 per cent.

Mortar. Bricks are laid in mortar made of lime or cement, according to the strength required. Lime mortar should not be used in damp situations, or where great strength is required. The difference in cost of lime and cement mortar is so little that cement mortar is generally* used.

The building laws of some cities require brick work to be laid in cement mortar for a certain part of the height.

Cement mortar makes a darker joint, but where a white joint is required it can be obtained, without loss of strength, by using Portland cement and lime mortar.

Cost. The cost of brickwork by the thousand in various kinds of mortar may be analyzed as follows:

In 1-3 lime mortar,

1,000 bricks

$ 9.00

3 bu. lime at $.36 per bu.

1.08

1/2 load of sand at $1.75 per load

.88

10 hours, mason at $.60 per hour

6.00

10 hours, tender at $.30 per hour

3.00

$19.96

In 1 - 3 Rosendale cement mortar:

1,000 bricks

$9.00

1 1/2 bbl. Rosendale cement at $1.20

1.80

1/2 load sand

.88

10 hours, mason at $.60 per hour

6.00

10 hours, tender at $.30 per hour

3.00

$20.68

In 1 - 3 Portland cement mortar:

1,000 bricks

$ 9.00

1 1/4 bbl. Portland cement at $2.10

2.62

1/2 load sand at $1.75

.88

10 hours, mason at $.60 per hour

6.00

10 hours, tender at $.30 per hour

3.00

$21.50

From these tables we may deduce an approximate estimate in round numbers as follows:

1,000 bricks laid in 1 - 3 lime mortar

$20.00

1,000 bricks laid in 1 - 3 cement mortar

21.00

1,000 bricks laid in 1 - 3 Portland cement mortar

22.00

So that, on a job of ordinary size, the difference between lime and cement mortar ought not to be considered, where cement mortar will give assurance of greater stability.

Face Bricks. Face bricks in great variety, are to be had either plain or moulded, and in a variety of colors. On ordinary face brickwork a mason with tender will lay about 300 to 400 bricks in a day.

Faced bricks cost from $25.00 to $50.00 per thousand; a good average brick can be secured for $32.00. This will make the price for a thousand, laid, about as follows:

1,000 face bricks

$32.00

1 1/4 bu. lime at $.36

.45

1/2 load fine sand at $1.75

.88

3 days, mason at $4.80

14.40

1 1/2 days, tender at $2.40

3.60

$51.33

From this we find that 1,000 face bricks can be laid in the wall for $51.33 of which $33.33 goes for stock and $18.00 for labor.

Enameled bricks are to be had in various colors, white and buff being the most common. These bricks cost from $50.00 to $60.00 per M.

Concrete. Concrete is used to a great extent now for footings, walls, piers, etc. The cost of concrete is not a great deal different from stone for foundations and if there is uncovered a deposit of suitable sand and gravel, as is sometimes the case, it can be put in at a less price than a granite footing.

Concrete with a reinforcement of steel is used in various forms for piers, floors, and walls.

The cost of a cubic yard of concrete, using the proportion of 1-3 and 6, may be summarized as follows:

1 bbl. Portland cement

$2.10

3 bbl. sand

.75

6 bbl. broken stone

2.00

Mason, 2 hours at $.60 per hour

1.20

Laborer, 4 hours at $.30 per hour

1.20

$7.25

Cellar concrete 3 inches thick will cost $.60 to $.75 per square yard in place. Concrete of Rosendale cement can be put in at less cost, being for foundation walls about $6.00 per cubic yard; for piers $6.50 per cubic yard.
