The estimate for the concrete floor is arrived at as follows:
The concrete will be a 1-3-6 mixture. According to Estimating and Calculating Quantities, Part 1, this mixture costs $4.92 per cubic yard. According to the same section, 25 cents must be added to this cost for extra labor, bringing the total up to $5.17 per cubic yard. If the concrete floor is 4 inches thick, the cost per square yard will be ⁴/₃₆ × 5.17 = 57 cents, approximately. The top coat, according to Estimating and Calculating Quantities, Part 1, is 40 cents. Therefore, the total cost of the concrete floor per square yard is 57 + 40 = 97 cents.
Summary
| Footing concrete, as per foregoing figures, | |
| 19.8 cu. yd. at $5.10 per cubic yard | $100.98 |
| Concrete floor, 139.9 sq. yd. | |
| at 97 cents per square yard | 135.70 |
| Total cost of concrete | $236.68 |
| Recapitulation of Cost of Stonework | |
| Rubble masonry | $ 671.53 |
| Ashlar masonry | 123.63 |
| Cut stone | 761.99 |
| Concrete footings and floor | 236.68 |
| Total cost of stonework | $1,793.83 |
BRICKWORK
4. In estimating the brickwork, openings have been deducted, thus practically giving “kiln count,” so that the analyses of prices given heretofore will apply. If openings had not been deducted, the prices would be 15 per cent. lower.
Pressed Brick
Cost
The cost of pressed brickwork is based on the analysis given in Estimating and Calculating Quantities, Part 1, and is $53.71 per thousand.
