Ihe red line on the Ground Plan, Sheet 1, shews the centre lino of the Railway, as staked out on the ground. Embankments are coloured yellow on the Section, and Cut' tings red The red line on the Section describes the top of the Embankments, and the bottom of the Cuttings, previous to laying on the ballast. The black undulating line describes the present natural surfnr ■ of the ground along the centre of the line of Rail- way. . ..'^^^ figures on the section indicating the depths of cutting, are marked in blue those indicating the heights of Embankment in red, and show the distances from the suriace at the top of each stake to the red lino or formation level of the Railway • and the top of all the Embankments, and the bottom of all the Cuttings, shall accuratelVcoin- cide and range with the formation level, after the Embankments are fully consolidated Ihc formation level of both Cuttings and Emliankments shall bo as sbown on the Cross ♦Sections, Sheet 2, namely— inches higher at the centre than at the sides. The quantities in each Excavation and Embankment are marked upon the Longitu- dinal Section, Sheet 2, and every care has been taken to ensure their accuracy. Con- .tractors must however examine the grouad previous to tendering for the work, and satisfy themselves on this point, as well as of the acciracy of the lengths, depths, and quantities, marked upon the several Sheets, and of the nature of all the Cuttings, for when a tender has been accepted, no claim for extra work will, be allowed for any real or supposed inaccuracy, as the Contractor shall be bound to construct the Railway so that the gradients at the formation level shall be agreeable to the gradients marked on the ^Section, Sheet 2, with the ))rcadth and side slopes hereinafter specified, and accu- rately coincide in direction with the curves and straight portions drawn and marked iu rod on the Ground Plan, Sheet No. 1. The Cuttings "shall be 22 feet broad at formation level, with side slopes of 1 lionzontal to 1 perpondiculav, and tho breadth of Embankments 18 feet at the same level with s^do slopes of 1 ami 1-2 hori/(mtal to 1 i)orpend;cular, except the slopes of Embank- mtnt J\o 1, composed entirely of loose rock, which shall have aslope on the seaside of 1 and 1-2 horizontal to 1 perpendicular, and on the shore side of 1 horizontal to 1 perpendi- cular ; and especial care must be observed in forming the slopes of this Embankment to these inc linations. Tho parts of this Embankment upon which this Bridge is to bo OTOc e. , shall be carofuUy formed of largo stones up to low water level, ajid the openings sha 1 tliru bo liHcd m with sinaller stones, so as to bring the whole mass upon which the bridge is to stand to a uniform surface previous to laying the foundation stones 'b' A Enibaukments are to be formed frrmi the nwlerial taken out of the excavations on tlw^ Hne so far as they go, and the ilefieiewy shall be made up by loose rock, procured and deposited at the Contractor's risk and expense ; but no material taken out ot any excavation on the Hue of Road, except it be rock, slmll form part ot the slopes of No. 1, Embankment. The Contractor, when required by theEngincoivshallcut, on the high side of slopes of Cuttings and Embankments, a side ditch of the form and dimensions shewn on the Cross Sections, Sheet 2, inclining towards the level courses, and drains, so- as to convey the water into the same, and thereby prevent its washing away the slopes or inouiing the roadway. A.t the points where- diversions of water ccjwrses shall be made, the ancient beds thereof are to be stopped at the upper end, as the Engineer shall direct. Whenever in cutting through a brook or drain, the level of the Railway, or of the small ditches on the sides of the Railway, shall be lower thsm su-ch brook or drain, then, in order that the Avater may not flow upon the Railway, or by the sides thereof, a level shall be brought up to the lower side of the line or track, of such t, ifepth, that the water may flow freely by means of a drain under the Railway ; or the said brook shall be diverted in its course, in either case, as the Engineer shall direct. The Contractor shall be bound to chop down and clear away all Trees standing or lying on the ground set off for the Railway. All Timber used in bridging shall be of well seasoned Pine, free from defect of every kind, and the planking shall be of Hemlock, S incites thick, well .spiked down t> the ]3eams with six inch spikes. The foundation stones in all Mason work shall project 6 inches on eacfr side of the Avail, and no stone shall have an area less than 9 superficial feet,, iwr be less than C inches' in depth. If considered necessary to lay a frame work of timber under the foundation stones, the Contractor shall do so in the manner to be directed by the En- gineer. The Walls or Abutments and Wing Walls,, shall be of the dimensions shown: in the Drawings, Sheet 3, and shall be built of Rubble Masonary, laid in Hydraulic lime. This Avork shall consist of dressed stones, placed on their natural bed; no stone to have less thi.n three superficial feet, and to be laid so as to b-er!: bond, and each course tied together by headers three feet six inches by tAve feet, and not more than six feet apart. After the profile of the natural surt^ice has been reduced to the gradients awd inclinations hereinbefore specified and as marked upon the Longitudinal and Cross Sec - tior the Contractor must then provide and spread the permanent road Avith ballast to the , xcadth of 14 feet and dei>th of 1 foot ; the ballast to consist of clean gravel or stc«e, broken so that each piece shall ixiss each Avay through a ring 2 inches in diameter. There is included in this Contract a deviation of the Windsor Road, as shown on Plan and Section. In making this Road alteration,, the Contractor shall take care that neither it nor the Railway operations shall impede or in any way intefere Avith the Road traffic, as for all such damage or intcfercnco he shall be held responsible. The ncAV Roadway is to bo excavated and embanked, so as to be 22 feet G inches wide at formation level, Avith side slopes of 1 horizontal to 1 perpendicular, and brought to tlie grades shown on the section,— it is to be rounded ofl", so as to admit of proper drain- age, and covered for the breath of 18 feet and depth of inches, Awith clean gravel. The Contractor must provide all materials and workmanship, of the best descrip- tion, at his own expense, necessary for carrying on and completing:; the work. The Avholo work licrein specified shallbc completed on or before the Eifteenth day of December, 1854, under a penalty of Ten Pounds pcrday aftcrwards,-to be retained by the Commissioners from the prices agreed upon. flr i I 4 i ?T Pay Bills shall be uuule up and puyineiits ma.le monthly, or lortui^'htly, in iho discretion of the Commissioners, accortling to the Schedule of Prices hereto uttacheil, for work completed, on Certiacates being granted by the Chief Engineer ; less ten per cent, to remain in the Commissioners' hands until the Chief Engineer has certified that the Contracts are completed in a workmanlike manner, and to his entire satisfaction. Should the Works not be carried on at such a rate, as, in the Engineer's opinion, to insure tlieir completion, within the specified time, the Commissioners reserve to them- selves power, on three days notice given, at any time, to take the whole or any portions of the work into their own hands, and complete the same at the Contractor's expense. The Commissioners reserve to themselves the right of making alterations at any time, either in the location, curvatures, gradients, orrature of the works contracted for, and of requiring extra operations of any kind whatever, either in the making, draining, or finishing of the works contracted for ; but such alterations, or any additional labour, shall in no way aficct contracts entered into farther than that the same shall be paid for as extras, at like rates as other work contracted for ; and they reserve a like right to withdraw any portion of the work contracted for, and prevent its being performt J, and thereupon to make a corresponding deduction in payment. The whole of the foregoing to be executed in a good workmanlike manner, and to the satisfaction of the Chief Engineer for the time being. Should any dispute arise as to the true meaning and intent of this specification, the same shall be referred to the Chief Engineer for the time being, whose decision shall be binding on both parties.
