MISCELLANEOUS _Quantities_ LINEAR FEET FEET B. M. Lookouts: 50 pieces, each 3" × 1" × 2', cut from 8' 25 37 pieces, each 6" × 1" × 2', cut from 8' 37 Furring, for brick walls, 1" × 2"; ⅙ ft. B. M., per lin. ft.: 125 pieces, each 11', order 12' 1,500 250 ----- ------ Grand total of framing 18,578

[12] Where studs over 20 feet are required, it is sometimes more economical to use two short studs, inserting a plate over the first-story studs and resting the feet of the second-story studs thereon.

_Cost_

The price of the framing is based on the following cost of 1,000 feet board measure of hemlock, which includes framing.

1,000 ft. of hemlock $28.00 Nails and spikes, allowing 100 lb. to 3,000 ft. of lumber, at $2 per 100 pounds .67 [13] Cost of framing, per 1,000 feet of lumber 12.00 ------ Cost per thousand feet B. M. $40.67

[13] This value would appear high if compared with Table VI, _Estimating and Calculating Quantities_, Part 1, but this table represents ideal conditions, where there are no delays, mistakes, legitimate office expenses, nor foreman's time included.

_Summary_

The amount of material, as previously estimated, is 18,578 ft. B. M., which, at $40.67 per M, will make the total cost of framing $755.57.

SHEATHING _Quantities_ FEET B. M. Main roof, 2,200 sq. ft. × 1 in 2,200 Tower roof, 370 sq. ft. × 1 in 370 Porch roof, 637 sq. ft. × 1 in 637 Outside walls, laid diagonally, 2,417 sq. ft. + 10 per cent. 2,659 ----- Total sheathing 5,866

SHINGLES _Quantities_ Area to be covered (see wall sheathing), 2,417 sq. ft.= 24.2 squares Shingles, 4 in. wide, and 5 in. exposure, number per square 720 Number of shingles required, 24.2 × 720 17,424 Add 5 per cent. for waste 871 ------ Total shingles 18,295

_Cost_

The cost of sheathing in place is assumed to be the same as that for hemlock lumber, $40.67 per M. The total sheathing is 5,866 square feet, which, at $40.67 per M, will make the cost of sheathing $238.57.

The cost of shingles is based on the following analysis of the cost of 1,000 shingles in place:

1,000 shingles XXXX $ 5.50 [14] Labor: one man can lay about 700 shingles per day; wages being $3.20, 1,000 will cost 4.57 Nails (about) .25 ----- Cost per thousand $10.32

[14] Usually a man can lay more than 700 shingles per day, but the roof under consideration is very much cut up.

From the preceding estimate, the number of shingles required is 18,295, which, at $10.32 per 1,000, will make the cost of shingles in place $188.80.

_Summary_ Sheathing $238.57 Shingles 188.80 ------- Total cost of sheathing and shingles $427.37

FLOORING _Quantities_ SQUARE FEET First floor, area (net) 1,312 Second floor, area (net) 1,312 Attic floor, area (net) 1,071 Porch floors, area (net) 523

HEMLOCK UNDERFLOORING

Unmatched underflooring is used under the first and second floor. Its quantity is 1,312 × 2 = 2,624 feet B. M.

RIFT-SAWED YELLOW-PINE FINISH FLOORING

The total area of the first, second, and third floors is 3,695 square feet. Adding 25 per cent. for waste, the quantity of ⅞-inch flooring is 3,695 square feet + (3,695 × .25) = 4,619 feet B. M.

YELLOW-PINE PORCH FLOORING

Increasing the net area of the porch floor by 25 per cent., the flooring required is 523 square feet + (523 × .25) = 654 feet B. M.

_Cost_

The estimated cost of flooring may be analyzed as follows:

_Cost of 1,000 Feet B. M., Rough Flooring_ [15] 1,000 ft. B. M., hemlock $27.00 Labor 10.00 Nails, 33 lb., at $2 per 100 pounds .67 ----- Cost per thousand feet B. M. $37.67

_Cost of 1,000 Feet B. M., Finish Flooring_ 1,000 ft. B. M., rift-sawed yellow pine $55.00 Labor, including striking joints 16.00 Nails .67 ----- Cost per thousand feet B. M. $71.67

_Cost of 1,000 Feet B. M., Porch Flooring_ 1,000 ft. B. M., No. 1 yellow pine $45.00 Labor 16.00 White lead for joints (about) .50 Nails .67 ------ Cost per thousand feet B. M. $62.17

[15] The cost of this hemlock is $1 cheaper per thousand than that used in the framing, since shorter lengths may be employed.

_Summary_ Hemlock, 2,624 ft. B. M., at $37.67 per M $98.85 Rift-sawed yellow pine, 4,619 ft. B. M., at $71.67 per M 331.04 Yellow pine, 654 ft. B. M., at $62.17 per M 40.66 ------ Total cost of flooring $470.55

PORCH CEILING, YELLOW PINE _Quantities_ FEET B. M. Porch ceiling, same as porch flooring 654

_Cost_

The cost of yellow-pine ceiling is $45 per thousand feet B. M. Since there is no white lead to be used and the joints are not struck, $11 will pay for laying it. The nails will cost 67 cents, which will bring the cost per thousand feet B. M., up to $56.67. Therefore, 654 feet B. M., yellow-pine ceiling, at $56.67 per thousand, will cost $37.06.

CORNICE, SPANDRELS, ETC., WHITE-PINE DRESSED LUMBER _Cost_ Cornice, 393 lin. ft., at 50 cents per foot $196.50 Spandrels, 357 lin. ft., at 12 cents per foot 42.84 Base, 128 lin. ft., at 6 cents per foot 7.68 16 porch posts, 8" × 8" × 9' at $4 each 64.00 ------- Total $311.02

_Summary_ Yellow-pine ceiling $ 37.06 White-pine dressed lumber 311.02 ------- Total $348.08

_Recapitulation of Cost of Carpentry_ Framing $755.57 Sheathing and shingles 427.37 Flooring 470.55 Porch ceiling, cornice, etc. 348.08 --------- Total cost of carpentry $2,001.57

ROOFING

=6.= Roof framing and sheathing are included in the estimate for carpentry. Following are given the estimates for slating and miscellaneous roof items:

SLATING _Quantities_ SQUARES Main and dormer roofs 22.0 Porch roof 6.4 Tower roof 3.7 ---- 32.1

_Cost_

The price of slating per square is given in Table XII, _Estimating and Calculating Quantities_, Part 1. Bangor slating costs $8 per square. On account of the curved tower and the number of hips and valleys, and because the measurement just given is actual measurement, the price will be put at $10 per square. Thus, the cost of 32.1 squares at $10 will be $321.

MISCELLANEOUS ITEMS[16] _Quantities and Cost_

Tin roof on bay window, 38 sq. ft. at 20 cents per square foot $ 7.60 Tin for valleys, 191 sq. ft., at 18 cents per square foot 34.38 Flashing around chimneys and dormers, 90 sq. ft., at 10 cents per square foot 9.00 Gutters, 100 lin. ft., 26 in. wide, at 28 cents per foot 28.00 Conductor pipe, 4-inch galvanized iron, 146 lin. ft., at 20 cents per linear foot 29.20 Terra-cotta ridge tiles, 70 lin. ft., at $1 per linear foot 70.00 3 terra-cotta finials, 2 ft. high, at $8 each 24.00 Tower finial, copper 30.00 ------- Total $232.18

_Recapitulation of Cost of Roofing_ Slating $321.00 Miscellaneous 232.18 ------- Total cost of roofing $553.18

[16] The prices given include the cost of labor.

LATHING AND PLASTERING

=7.= Plastering varies in price according to its position and quality. It is therefore necessary to make a separate schedule of each class of work, so that any increase or decrease in quantity may be easily added to or deducted from the estimate.

THREE-COAT WORK _Quantities_ SQUARE SQUARE FEET YARDS First-story walls, 542' × 9' 9⅜" 5,284.5 First-story ceiling (take measurement of flooring) 1,312.0 Second-story walls, 609' × 9' 5,481.0 Second-story ceiling 1,312.0 Attic walls, 190' × 8' + 156' × 6' 2,456.0 Attic ceiling 831.0 -------- Total of three-coat plastering 16,676.5 1,853

TWO-COAT WORK SQUARE SQUARE _Quantities_ FEET YARDS Cellar ceiling, use same measurements as for concrete cellar floor 139.9

CORNICES _Quantities_ LINEAR FEET

Cornice, 147' of 2' girth 147 Cornice, 493' of 1' girth 493

_Cost_

The cost of three-coat plastering is given in _Estimating and Calculating Quantities_, Part 1, as 31 cents per square yard, and two-coat work, as 23 cents per square yard. According to the same section, lathing costs 12 cents per square yard. Therefore, lathing and plastering for three-coat work cost 43 cents per square yard, and for two-coat work, 35 cents per square yard.

The assumed cost of plain, run stucco cornice per linear foot of 2-foot girth is 31½ cents, and the cost per linear foot of that having a 1-foot girth is 27 cents.

_Summary_

From the preceding estimates of quantities and costs, the following figures are obtained:

1,853 sq. yd. of three-coat work, at 43 cents per square yard $ 796.79 139.9 sq. yd. of two-coat work, at 35 cents per square yard 48.97 147 ft. of cornice at 31½ cents 46.31 493 ft. of cornice at 27 cents 133.11 --------- Total cost of plastering $1,025.18

JOINERY

=8.= As there are so many different sizes in the joinery work, no attempt has been made to make detailed estimates of the cost of each; but the general method of obtaining the costs is that given in the articles on Joinery, in _Estimating and Calculating Quantities_, Part 1. Since the quality of the work varies in different parts of the building it will be found that one unit price will not be sufficient, but experience is needed to fix the unit price for different classes of work.
