In case an increase in quantity of an individual item by more than 25% of the agreement quantity is considered unavoidable, the same shall be got executed by floating a fresh tender. If floating a fresh tender for operating that item is considered no practicable, quantity of that item may be operated in excess of 125% of the agreement quantity subject to the following conditions:

(iii)Variations in quantities of individual items beyond 150% will be prohibited and would be permitted only in exceptional unavoidable circumstances with the concurrence of associate finance and shall paid at 96% of the rate awarded for that item in that particular tender.

(b) The variation in quantities as per the above formula will apply only to the Individual items of the contract and not on the overall contract value.

CHAPTER II

DETAILED TECHNICAL SPECIFICATIONS FOR CARRYING OUT SIGNALLING WORKS

GENERAL:- 0.1 The detailed specification for the works which are to be carried out by the contractor are as stipulated hereunder:-

0.2 The work shall be carried out according to the drawings approved by the Railways and shall conform to the provision in Signal Engineering Manual and Schedule of Dimensions. The contractor shall be solely responsible for the proper execution of the work as per specification.

1.0 CABLE LAYING :- 1.1.1 CABLE TRENCH :- Excavation of cable trench shall be made in all kinds of soils including clearing roots of trees, rocks bushes etc., to a depth of 1.0M and a width of 0.3M/ 0.5M as required, for laying cables. Trenches shall be straight as far as possible and steep angles shall be avoided. Alignment of the main cable route as well as track/ road crossing will be given by Railways. While taking the trench, all the roots of trees, bushes, rocks, if any, should be cleared. The bottom of the trench shall be leveled and got rid of any sharp materials. Proper protection to cables to be given while crossing power cables, pipe lines, etc., as required by Railways.

a. Signalling/power cables will be laid as close to the track as possible. The cable, track separation distance both within station limits and in the block section shall generally not exceed 6 Metres.

b. It is desirable that the excavation of trenches is not done in long lengths and does not remain uncovered overnight. It is preferable that trenches are dug, cables laid and refilling done on the same day.

c. The contractor who supervises the excavation work shall have the shoring materials ready on hand so that on banks where ashes or loose materials are encountered, shoring can be adopted.

d. During excavation, the earth of the trenches should not be thrown on the ballast. The earth should be thrown by the side of the trenches away from the track. Plastic sheets/gunny bangs may be used wherever necessary to cover the ballast.

1.1.2 In RE area the following clear distances shall be maintained between the signalling cables and the OHE mast or other structures likely to develop high potentials or switching stations earth. a) Minimum distance between the signalling cables and OHE masts or other structures likely to develop high potential or switching stations earth.

DEPTH OF CABLE (Metres) DISTANCE (Metres) REMARKS Upto 0.5 1.0 Provided cable is laid in 0.5 concrete pipe for 3M on

64 65

More than 0.5 3.2 either side of the mast/structure b) Minimum distances between signalling cables and OHE mast or switching station earth. DESCRIPTION DISTANCE (Metres) REMARKS Switching station viz., 5.0 Provided cable is laid in feeding posts, sectioning 1.0 concrete pipes. post or sub-sectioning post Earth, OHE mast or sub- 1.0 station earth

1.2 LAYING OF CABLES :- 1.2.1 Before the cables are laid, a visual inspection of cable shall be made and it shall be tested for insulation and continuity of the cores. The insulation resistance of a new cable shall not be below 500 M.Ohms per Km. at 20 deg C. The cable insulation should be measured using a 500V insulation Tester(Megger). If there is wide disparity between insulation of different conductors, the condition of the cable should be thoroughly checked before permitting its use. Bedding and armouring shall be inspected to see that there has been no damage during transit or in storage. In case where the wheels are not available or the area is not convenient for rolling the wheels, along the routes, the drum shall be mounted on the axle at one end of the trench and cable payed out. It should be carried out by adequate number of men, ensuring that the insulation of the cables is not damaged and no kink/twist is formed. In no case shall the drum be rolled on the road for laying of cables and the cable dragged on the ground for laying purposes. The cables shall be laid gently into the trench and not thrown out under any circumstances. Before laying of cable in the trench, a visual inspection shall be adequate for any damage or defect throughout its length. Normally cable laying should be commenced only after the relay room and apparatus cases, cable termination box on the route at the respective stations are ready and the cable should be duly brought inside at the relay room/apparatus cases immediately after the cables are laid, however, if for any reasons the cable is be laid in advance, special care should be taken to ensure that the coiled cable near the relay room/apparatus cases is fully protected before and during the construction of the relay room/apparatus cases and during final termination. The coiled cable shall be buried well in the ground such that the depth from the ground level to the top layer of the coil shall not be less than 1 M and shall be fully covered with a layer of bricks horizontally in its entire length and provided with adequate number of the cable markers. On no occasion, the ends of the cable should be left unsealed unless terminated properly.

1.2.2 Cable laying shall commence after the depth and width of the cable trench, quality of bricks are jointly inspected by Railway Engineer's representative and contractor's representative and approved.

1.2.3 PLACING OF CABLES :- When several cables of different types have to be laid down in the same trench, they shall be as far as possible in the following order starting from the track side. i) Telecommunication cables. ii) Signalling cables. iii) Power cables.

65 66

1.2.4 Cable shall not be normally taken over the running track at the time of cable laying by the contractor as this is likely to cause accident to trains and damage to cables. If at any time the cable has to be taken across the track either in full drums or in spread out conditions it shall be done only in the presence of Railway's Supervisory staff and also after safety precautions have been taken to post flagmen on all the sides as may be required to stop any trains approaching the site of the fouled line. 1.2.5 At each end of the main cable/tail cable/power cable an extra coil length of 6 to 8 Metres should be kept.

1.2.6 At the time of commissioning of the cable, the insulation values of the cable should again be checked and the value obtained shall not be below 500 Meg.Ohms per Km at 20 deg.C. If there is wide disparity between insulation of different conductors, the condition of the cable should be thoroughly checked before permitting its use. The reading shall be recorded in a register based on Annexure `C' for all power cables, main and tail cables.

1.2.7 The contractor shall furnish the final as made cable plan and cable route plan and in R.P film with eight prints showing the distance of cables from the nearest track centre.

1.4 RE-FILLING THE CABLE TRENCH : After the bricks are placed over the cable without any gap between two bricks properly, the excavated earth, shall be again put up in the trench. It shall be ensured that there are no stones or any sharp materials present. The refilled earth shall be consolidated and extra earth also shall be placed on the trench to compensate the sinkage and consolidation of earth.
