Rolling.

4. The work of rolling the surface should be commenced as soon as a section of about 20 or 30 yards in length has been laid, the metalling gang being kept as busily employed as possible in laying a further length of materials in the way specified above. The prepared road surface is to be rolled with a light six or ten-ton roller when the composition is soft, as it is absolutely necessary to press the aggregate gently down into the bituminous sub-binder, and at the same time to entice (rather than to force) the latter in an upward direction, so as to fill the voids in the metal and finally cover the metalled surface. Under no circumstances should the rolling be carried to such a point that the metal exhibits signs of crushing or disintegration. The roller should be driven over the newly laid materials at its lowest speed from the side towards the centre and after a few journeys over the surface if it is found that the sub-binder is not working up between the voids in the metal and does not cover the metal surface, then such defective places have to be painted and the whole surface sealed with composition to prevent the admission of moisture or of any foreign substance into the road. During the process of consolidation stone chippings at the rate of 4 cubic feet per hundred square feet should be used and especially where the floated composition is too soft. If it is found that any material sticks to the roller wheels a little water sprinkled on the wheels will at once stop the sticking. The dry surface may be also sanded if it becomes slippery for horses.

5. All materials to be supplied must be to the satisfaction of the Engineer. Inferior materials supplied shall be rejected and the contractor must make good such supply within 24 hours. In default it shall be competent to the Engineer to procure a supply of the same at the risk and cost of the contractor from the market or any other agency.

6. The contractor must maintain the roadway for three months after completion and keep men in attendance to promptly spread stone chips and road dust on the soft portions and nurse the area cut up by the traffic.

7. The contractor must be careful not to injure existing gas, water or any other pipes or drains or other underground fixtures. Any damage so caused must be forthwith reported to the District Engineer, and the contractor shall make good the same forthwith at his own cost and shall indemnify and keep indemnified the Corporation from all claims made therefor. When necessary he shall take up and carefully relay drains and pipes and lay any additional length that may be ordered by the Engineer at the cost of the Corporation.

8. The contractor must keep the work properly fenced and lighted from sun-set to sun-rise, and place such watchmen at any portion of the road and footpath in which the work is in progress and is still incomplete, and also round the repairing materials for use, as may be necessary to protect the public against accidents. He shall indemnify and keep indemnified the Corporation and its officers and servants from all liability in respect of any claims for damages or otherwise to person or property which may be made by any person or persons on account of any act, misfeasance or neglect on the part of the contractor in carrying on the work or in connection therewith.

9. The contract will be for four months and the contractors must carry out all works in accordance with the full programme of work prepared by the Engineer and take in hand such street or streets as the Engineer may direct and complete the same within such period as the Engineer may fix therefor. In default he shall pay to the Corporation liquidated or settled damages of Rs. 10 (ten) per diem for each and every day beyond the said period without prejudice to the rights of the Chairman to cancel the contract and take possession of the work and have it carried on and completed at the contractor’s risk and cost by any agency whatever.

10. All damages or other sums due and payable by the contractor may be received from any moneys due to the contractor by the Corporation.

11. Payments will be made in accordance with the terms of the agreement.

12. The Commissioners do not bind themselves to accept the lowest or any tender, but reserve the right of accepting the whole or part of the tender.
