The locks for whose construction bids will be received are numbers 2, 3, 4, 6, and 7; bat awards will be made for the construction of only so many of these, beginning with umber 2, as the amount of funds available for this purpose and the prices bid may #arrant. The lots are to be three hundred (300) feet long between mitre-sills, sixty (60) feet wide, and of five (5) feet lift, with chamber-walls about thirteen feet high. The lockpit excavations will be about four hundred (400) feet in length by eighty (80) feet in breadth, and are to be carried down to the limestone rock substratum, and into it where required. Timber and concrete floors will be used where the substratum is so ricked and faulty as to render them necessary. The entire work must be executed in accordance with the working-drawings, which shall be furnished from time to time as they are needed. Each bid offered must relate to one lock only, designating it by its number, and tist cover the cost of furnishing all the material and doing all the work called for by these specifications, viz: 1. Earth excavation.-Price per cubic yard, measured in excavation. This must over the preparation of the site by clearing and grubbing, and the excavation, removal, and deposit where directed of all earthy and stony material, except rock which cannot be removed without first breaking or blasting it. 2. Rock excavation.-Under this head is to be included only such rock as cannot be readily moved without first breaking or blasting it. Its price must be per cubic yard, measured in bed, and must cover the cost of excavating, removing, and depositing where directed, as well as the cost of any necessary preliminary clearing or preparation of site. 3. Timber.-Price per thousand (1,000) feet, board measure, in place. This must cover the furnishing, preparing, or fitting and fastening in place of all timber and plank required in the work. 4.

The lock-pits must be freed from water before the concrete or masonry work is begun, and must be kept so during the progress of the work. Any concrete or masonry laid in water must be taken up by the contractor at his own expense, and no payments of any kind will be made him until this is done. Every expense which it may be necessary to incur in order to carry on the work in accordance with the plans and specifications, such as supplying tools, material, workmanship, labor, scaffolding, derricks, machinery, constructing coffer or other dams, pumping, bailing, draining, removing rubbish and unused material while the work is in progress and after its completion, et cetera, must be borne by the contractor, and should be covered by the prices bid for excavation, masonry, or concrete, as no separate allowance will be made, under any circumstances, for such expenditures. Material will be paid for only when it is permanently placed in its final position in the work, and is then approved and accepted by the engineer in charge. Mere delivery of material at the work, or labor of any kind expended upon it, shall not entitle the contractor to any payment therefor. The contractor must be responsible for the protection of the work until his contract is closed, and must repair any damage done to it by freshets, rains, overflows, et cetera, in such manner as the engineer in charge may direct, but at his own expense. Before receiving his final payment he must, at his own expense, remove all dams and other material and work temporarily used by him under his contract, and must secure the work from the weather, as may be required. MATERIALS AND WORKMANSHIP. All materials and workmanship must be such as shall be approved by the engineer in charge, and must be carefully examined, either by himself or by a duly authorized inspector acting for him. Rejected material must be removed at once from the work and vicinity. Masonry not approved must be taken down. No payment will be made for any material or work so rejected or disapproved.

Iron, wrought and cast.-To be of good quality American iron, free from defects. Bolts and clamps to be of best quality. LAYING FOUNDATIONS AND FLOORS. Where these are used, trenches are to be cut in the rock bottom for the whole length of the walls to receive eight rows of yellow pine timber twelve (12) inches square, laid longitudinally and bolted at intervals to the rock bottom. The trenches must be cut so that these timbers shall lie horizontally and shall be supported throughout their entire length. Transverse timbers of the same wood, with the same cross section, shall be laid upon the longitudinal timbers at right angles with them, and six (6) inches apart in the clear; and shall be bolted to the longitudinal timbers and to the intermediate masses of rock. The spaces between these timbers shall be filled with concrete well rammed.. The floor will consist of two layers of two (2) inch yellow pine plank, laid and spiked as may be directed. Cut stone.—Must be of perfectly sound, strong, and durable quality, free from seams, faws, cracks, scales, earthy matter, or other defects, and not easily injured by the action of water, air, or frost, and the blocks should be of the same general color and appearance. Facing.-To be laid in regular courses, headers and stretchers; no course to have a height less than fifteen (15) inches or greater than two (2) feet. Each stone to have at least one-third more bed than rise. Stretchers to be not less than three and a half (34) feet or more than six (6) feet in length, and to break joints by at least a foot with the stretchers upon which they rest. Headers to be either six (6) feet in length or "throughs"-to be not over twelve (12) feet apart in each course, and to be so placed as to fall near the middle of the interval between two adjacent headers of the course next below. Beds to be cut parallel to each other and to the quarry bed. perpendicular to the beds and to the exposed face. Vertical joints to be Beals and vertical joints to be dressed to true planes without projections, cavities, or wind; the former eighteen (18) inches and the latter ten (10) inches back from the exposed face to admit of being set with three-eighths (4) inch joints. The remaining parts of these surfaces to be broken or pointed off smoothly to admit of joints not exceeding one inch in thickness. Exposed faces to be dressed with care-cut true and even, with clean angles and perfect edges, and without marking or spalling. The hollow quoin must be formed by a single stone in each course, three (3) feet wide and seven (7) feet long, laid alternately as headers and stretchers. The stones in each course at the angles of the head bay and tail bay to be not less than three (3) feet by six (6) feet, laid as headers and stretchers, and dowelled to the stones above and below them by cast-iron dowell one and a half (14) inches in diameter and eight inches long. The facing of the mitre-sill wall shall have its bed and vertical joints dressed throughout to true planes, to lay a quarter (†) inch joint, the courses to be dowelled together, and the exposed face to be left rough with the exception of a draft line one inch wide around its edge, cnt with great exactness. The coping is to be eighteen (18) inches in thickness, and each stone must be at least three (3) feet wide, and long enough to stretch across the top of the wall, except where it is buttressed. Each must have a bed whose area is not less than fifteen (15) square feet, must be dressed true on all sides, and must be dowelled to the course below it and clamped to the coping stones next to it, as may be directed. The dowells to be of cast iron twelve (12) inches long and two (2) inches in diameter; the clamps, of wrought iron, not less than eighteen (18) inches long, one and a half (14) inches broad, and three-quarters (4) of an inch thick, to be let in flush with the surface and to enter the coping about four (4) inches. The cement for fastening the dowell and clamps to consist of lead and antimony. The upper edge of the coping next the lock chamber will be rounded to a radius of three inches. The foot of the coping will be set even with the exposed edge of the apper course of masonry, and this exposed angle will be beveled off for a width of one and a half (14) inches, and to an angle of sixty (60) degrees. Rabble.-ust consist of strong, sound, and durable stone, free from crack, scale, or earthy matter; and where it is to be exposed to the action of the elements, it must be of a kind not readily disintegrated by them. When rubble backing is used, the coursing may be irregular, except where it unites with face work, in which case its horizontal joints must course with those of the face work as far as may be required. No stone shall have a less rise than ten (10) inches, nor a less width of bed than sixteen 16) inches, and the area of its bed should not fall below four (4) square feet. A stone of less rise or less bed may, however, be used occasionally as a leveller or to fill a small space. The stone to be used in rubble walls must be hammered or pointed down to good fair surfaces, square with each other, and to lay with horizontal joints not exceeding one inch. The stone should bond together not less than six (6) inches, and at intervals not greater than ten (10) feet; headers from four to five feet in length should be inserted, filling over the intervals between the headers of the course immediately beneath. Where the rubble and cut-stone facing unite, the rubble should set back an inch and a half, and the projecting angle of the cut-stone facing should be beveled or chamfered to an angle of forty-five (45) degrees. LAYING MASONRY. All the cutting, dressing, or drilling necessary for fitting a stone for the position which it is to hold in the work must be done before it is brought upon the wall, and H. Ex. 56- -3 it must then be lifted by a crane or derrick, and lowered into its place without shock to the masonry. Rolling or moving it while on the wall will not be allowed, and every stone whose bond or set is disturbed by shocks, however produced, must be taken up and reset at the expense of the contractor. Every stone, both of the facing and of the backing, will be set or laid in a full bed of mortar, to be made as hereafter described; and very great care will be taken that the vertical joints are thoroughly filled with the same, placed by the trowel, before the next course above is set or laid. Every surface which is to come in contact with mortar must be freed from dust and dirt and thoroughly wet just before the mortar is applied. Each stone, when permanently placed, must rest upon its quarry bed. Not more than three courses in either facing or backing are to be unfinished at a time; and the backing and filling, whether of rubble or concrete, are to go up with the facing, and are to be kept about even with the top of its last finished course. The joints of the facing will be pointed as the work progresses, using the same kind of mortar with which the stone is set, or such as may be prescribed. Cement.-Must be freshly burned and ground, and equal in quality to the best Rosendale. It should be a fine dry powder, must be free from inert matter, and must set strongly and firmly, but not too quickly. Every barrel of cement shall be tested upon its arrival, and such as are rejected must be immediately removed from the work. Every barrel will be tested again just before it is taken out for use in the work, and whenever else it may be desirable to do so, and it shall not be used unless it passes these tests. If rejected, it must be removed immediately from the vicinity of the work. In order to reduce the danger of deterioration, during the interval which elapses between the first and the last examination, contractors are advised to have the cement furnished them in water-tight casks, and to have a water-tight cement shed prepared for the protection of that which passes the first test. No fat or common lime, or cement which fails to pass the tests, is to be used in any part of the work. Sand.-Must be sharp, clean, rather fine, and free from earthy or vegetable matter; and must be screened and washed, if required by the engineer in charge or the inspector. Mortar.-Must consist of one part by measure of cement, and two of sand, with only enough water to form a stiff paste with it. It must be mixed thoroughly by means of a mortar mill just before it is to be used, and in such quantity only as is immediately needed. None that remains over from the preceding day, or stands long enough to need re-working, is to be used in any part of the work. If it be ascertained that any such mortar has been used in the work, the part which it enters must be taken down again and rebuilt with good mortar at the contractor's own expense. No work involving the use of mortar is to be done while the temperature is at or below thirty-two degrees (32°) Fahrenheit. Concrete.-Is to be composed of one part by measure of cement mortar, and three parts of gravel or broken stone, small enough to pass through a ring two-and-a-half (24) inches in diameter; the stone or gravel to be hard, strong, and free from dust, and to be wet or washed before mixing with the mortar, if required. The mixture to be made in the most thorough mauner by hoe and shovel, or by concrete mill, so that every piece of stone or gravel shall be entirely coated with the mortar. In placing concrete it shall be deposited in successive layers from six (6) to eight (8) inches thick, until the depth or thickness required is secured. Each layer to be thoroughly rammed and settled in place before the next is laid upon it. REMOVAL OF OLD LOCKS. The old locks are to be taken down. Such of the material of which their walls are composed as is approved by the engineer in charge may be used in the construction of the new locks. The remainder will be deposited where required. Bidders must state the price per cubic yard for which this work will be done, and the prices per cubic yard which they will pay for so much of this material as they may be permitted to use as facing and backing in the construction of the walls of the new locks. The amount of masonry facing will be determined by measuring the area of the exposed vertical face and allowing an average thickness of two (2) feet. All orders and instructions which may be given by the engineer in charge in relation to the prosecution of the work, details of construction, et cetera, are to be complied with by the contractor. APPROXIMATE QUANTITIES FOR ONE LOCK. Earth excavation, rock excavation.-Variable-Not exceeding one thousand (1,000 cubic yards. |
