New Clause 42(4) to Indian Railway General Conditions of Contract (Ref: Item -9 to Railway Board’s letter no.2007/CE.I/CT/18 Dt.28.09.2007 and Item -9 to letter no.2007/CE.I/CT/18 Pt.XII Dt.31.12.2010.

The procedure detailed below shall be adopted for dealing with variations in quantities during execution of works contracts:

a) Individual N.s. items in contracts shall be operated with variation of plus or minus 25 %

and payment would be made as per the agreement rate. For this, no finance

concurrence would be required.

b) 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 not practicable,

quantity of that item may be operated in excess of 125% of the agreement quantity

subject to the following conditions:

c) Operation of Item by more than 125% of the agreement quantity needs the approval of

an officer of the rank not less than S.A. Grade


(i) Quantities operated in excess of 125 % but upto 140 % of the agreement

quantity of the concerned item, shall be paid at 98 % of the rate awarded for that

item in that particular tender:

(ii) Quantities operated in excess of 140% but upto 150% of the agreement quantity

of the concerned item shall be paid at 96 % of the rate awarded for that item in

that particular tender :

(iii) Variation 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 be paid at 96% of the rate awarded

for that item in that particular tender.

d) 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.

e) Execution of quantities beyond 150 % of the overall agreement value should not be permitted and, if found necessary, should be only through fresh tenders or by negotiating with existing contractor with prior personal concurrence of FA& CAO/ FA&CAO(C) and approval of General Manager.

59. In case where decrease is involved during execution of contract:

(a) The contract signing authority cab decrease the items upto 25% of individual item

without finance concurrence.

(b) For decrease beyond 25% for individual items or 25% of contract agreement value the

approval of an officer not less than rank of S.A.Grade may be taken, after obtaining “No

Claim Certificate” from the contractor and with finance concurrence giving detailed

reasons for each such decrease in the quantities.

(c) It should be certified that the work proposed to be reduced will not be required in the

same work.

1. The limit for varying quantities for minor value items shall be 100% (as against 25 %

prescribed for other items). A minor value item for this purpose is defined as an item

whose original agreement value is less than 1% of the total original agreement value.

2. No such quantity variation limit shall apply for foundation items.

3. As far as SOR items are concerned, the limit of 25% would apply to the value of SOR

schedule as a whole and not on individual SOR items. However, in case of NS items, the

limit of 25% would apply on the individual items irrespective of the manner of quoting the

rate (single percentage rate or individual item rate).

4. For the tenders accepted at Zonal Railways level, variations in the quantities will be

approved by the authority in whose powers revised value of the agreement lies.

5. For tenders accepted by General Manager, variation upto 125% of the original

agreement value may be accepted by /General Manager.

6. For tenders accepted by Board Members and Railway Ministers, variations upto 110% of

the original agreement value may be accepted by General Manager.

The aspect of vitiation of tender with respect to variation in quantities should be checked and avoided. In case of vitiation of the tender (both for increase as well as decrease of value of contract agreement), sanction of the competent authority as per single tender should be obtained.


60. VITIATION CLAUSE:

Railway will exercise control over the aspect of vitiation of tender with respect to variation in quantities and take action as under: In the event of vitiation occurring due to increase or decrease in quantities among the first, second and third lowest valid tenderer, the vitiation shall be to Contractors account. The total value of the work done shall be calculated at the rate offered by those tenderers and the amount payable shall be limited to the lowest aggregate value as worked out. Vitiation amount shall be worked out for each and every on-account bill when the value of the work executed reaches 50% of the agreement value and the vitiated amount shall be adjusted at every stage.

61. FORCE MAJEURE CLAUSE

If at any time, during continuance of this Contract, the performance, whole or part, by either party, of any obligation under this contract shall be prevented or delayed by reason of any war, hostility, act of the public enemy, civil commotion, sabotage, fires, floods, earthquakes, explosions, strikes, epidemics, quarantine, restrictions, lockouts, statute, statutory rules, regulations, order of requisitions issued by any Government Department or Competent Authority or acts of God (here-in- after referred to as event) then provided notice of the happening of any such event is given by either party to the other within twenty one days from the date of occurrence there of neither party shall by reason of such event be entitled to terminate this Contract nor shall either party have any claim for damage against the other in respect of such non-performance or delay in performance, and the obligations under the Contract shall be resumed as soon as practicable after such event has come to an end or ceased to exist, PROVIDED FURTHER that if the performance in whole or part of any obligation under this contract is prevented or delayed by reason of any such event beyond a period as mutually agreed to by the Railways and the Contractor after any event or 60 days in the absence of such an agreement whichever is more, either party may at its option terminate the Contract provided also that if the contract is so terminated under this clause the railways may at the time of such termination take over from the Contractor at prices as provided for in the contract, all works executed or works under execution.

1. Instructions for Excavation and back filling of trenches.

1.1 The representative of engineer in charge of the work will mark the route of the cable in white chalk or lime as per the tapping and route plan and instructions given to him by the Engineer, notwithstanding the cable route shown in the tapping and route plan to meet the requirement of local conditions at site, if any and as required shall be taken by the Contractor to be final. The Contractor shall be present at the time of marking and he shall furnish to the Engineer’s representative required quantities of lime, rope, labour, etc, for carrying out the work. The marking will be given on the track side of the trench in the difficult terrains such as water logged areas the positions of the cable route will be specified by offsets from the center line of the nearest track.

1.2 Trenches for signal/telecommunication cable shall be dug to a depth of 1 mtr. The width of the trench shall be 0.3 mtr. at the bottom of the trench. In places where underground pipes, electric main, etc, come in the way trenches deeper than 1 mtr shall be dug as necessary and RCC pipes shall be placed to protect the telecommunications cables.

1.3 Metalled, macadamized, concrete and stone paved roads shall also be cut to a depth of 1 mtr. The cable shall be laid through RCC/GI/DWC/HDPE pipes as per Drawing No. SWR/DRG/TYP/0006. The road surface shall be restored to original.

1.4 The bottom of the trench where cable is to be laid shall be thoroughly prepared and shall be free from any stones. The bottom of the trench shall be horizontal and shall in no case be undulating. When the cable bed changes from solid to soft surface or from the bridge to soft soil, tamped fill at the transition point shall be provided so that the cable is not pressed against the edge of a hard surface.

1.5 The contractor shall arrange supply and distribution of second-class bricks of standard size site along the excavated trenches. He shall arrange to place the bricks flat and position them, breadth wise so that on an average nine bricks shall be laid in one meter length.

1.6 In order to be certain that the full requirement of bricks has been arranged by the contractor for placing them on the top of the cable to be laid on same day, he shall arrange to spread the bricks side by side on the top of the trenches before the depth of the trenches are jointly inspected with Railway’s, contractor.

1.7 The back filling of the trenches shall be done by ramming and consolidating the excavated

soil in layers of 15-20 cms at a time. All the soil that is excavated shall be put back filling does not suffer any sinkage in monsoon. The left out earth, if any within station limit has to be taken away from the railway premises by the contractor at his own cost.


1.8 The excavation shall include excavation of trial holes clearing bushes and roots of trees along the trenches.

1.9 Where the direction of the trench has to change, it should be done in a gentle curve of not less than one-meter radius and not at sharp angles.

1.10 Places where back filling is not done properly or likely to get water logged with the first rains after completion of the work, the contractor and the engineer in charge will inspect the entire section soon after the first monsoon and the contractor will arrange to set right such areas. The engineer-in-charge will then issue a certificate of satisfactory completion of this work and this shall constitute as one of the authorities for the refund of security deposit.

1.11 The detailed specifications for the work which are to be carried out by the Contractor are as stipulated hereunder:

adequate spare conductors in each cable as laid down in S36/87 i.e., 20% of working conductors on each cable shall be left spare up to outer most points and 10% beyond outer most points.

2.2 CABLE TRENCH:

Excavation of cable trench shall be made in all kinds of soils including clearing roots of trees, rocks etc., to a depth of 1mtr. and to a width of not less than 0.3mtr. providing proper protection as required by Railways while crossing power cables, pipe lines etc., The bottom of the Trench shall be leveled and got rid of any sharp materials. 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 crossings will be indicated by Railways. a) Signalling / Power cables shall be laid as close to the track as possible. The cable track separation distance both within station limits and in the block section generally not to exceed 6 Meters generally at both within station limits and in the block section.

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, cable laid and refilling done on the same day.

c) Wherever if rock formation is experienced and trenching cannot be done to a depth of 1 Meter, the trench shall be dug as far as possible and protective measures taken to avoid damages of cable as decided by the Railway's representative.

Where the trenching cannot be done to a depth of 1Meter, due site condition, in such locations. Payment of trenching shall be made proportionate to the depth of trench and minimum 0.75 mtr depth and no payment shall be made for any extra excavation carried out in the slope and width of the trench. The contractor, who supervises the excavation shall take the shoring materials ready on hand, so that on banks where ashes or loose materials are encountered, shoring can be adopted. However the minimum depth shall not be less


than 300mm for laying RCC pipes in hard morrum. Whenever rocky soil is experienced, concreting has to be done for a depth of 150mm after laying the cables to protect them.

d) During excavation of the trenches, the earth should not be thrown on the ballast. The earth should be thrown by the side of the trenches, away from the track. Complete excavated earth shall be back filled in the trench after laying the cable and well rammed. e) Whenever power cables are to be laid along with other cables bricks are to be laid lengthwise approximately five bricks per meter for separating power cables from other signalling cables.

3.0 SIGNAL POST TELEPHONE. 3.1 SPT (signal post telephone) PAGING AND TALK-BACK SYSTEM for HOME Signal Paging and talk-back facility in lieu of signal post telephone shall be installed including

voice communication equipment with suitable switching arrangement at Home signal post and at SM’s room. This work includes drawal of tail cable through GI pipe duly clamping to signal post with suitable offset as required at site, termination of tail cable at both ends. In the SM room console should be fixed ar per the direction of railway in-charge at site. The wiring shall be done with PVC 16/0.2mm copper tin coated wire.

3.2 MASONARY PLATFORM FOR SPT 3.2.1 This work includes excavation of pit, construction of masonary platform as per Drg. No.

SG/CN/02/12 with bricks of approx size 220x100x60mm to operate signal post Telephone near Home signal and plastering as per the instructions of Railway representative at site.

4.0 INSTALLATION OF ANNUNCIATOR :

The hard wood shall be covered with coloured Decolum sheet on all sides. The work also includes supply and wiring of Magneto telephone – 1 no. and Ni-cad power pack 4v DC – 2.2 AH with battery charger 110vAC/4vDC.

5.0 LAYING OF CABLE

Before the cables are laid, a visual inspection of cable shall be made and it shall be

tested for insulation and continuity of cores. The insulation resistance of new cable shall not be below 500 MΩ/km at 20 degree C. If there is wide disparity between insulation of

different conductors, the conditions of the cable should be thoroughly checked before permitting its use. Bedding and armoring 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 with route, the drum shall be mounted on the axle at one end of trench and cable paved out. It should be carried out by adequate number of men ensuring that the insulation of the cable is not damaged and no kink/twist is formed. In no case shall the drum be rolled on the road for lying 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 through out its length.

Normally, cable laying should be commenced only after the relay room and cable

termination box on the route at the respective stations are ready, and the cable should be fully terminated at the relay room/apparatus cases, immediately after the cables are laid.


However, if for any reasons the cables are to be laid in advance, special care should be taken to ensure that the coiled cable near the relay room/apparatus case is fully protected before and during final termination. The coiled cable should be fully covered with a layer of bricks in its entire length and provided with adequate number of cable markers. On no occasion the ends of the cable should be left unprotected. The cable ends shall be sealed with cable compound.

5.1 Cable laying shall commence only after the depth and width of the trench, quality of bricks

61.0 . CODE OF PRACTICE FOR EARTHING AND BONDING SYSTEM FOR SIGNALLING EQUIPMENTS

(i) Scope This document covers earthing & bonding system to be adopted for signalling equipments with solid state components which are more susceptible to damage due to surges, transients and over voltages being encountered in the system due to lightning, sub-station switching etc. These signalling equipments include, Integrated Power supply equipment, Digital Axle counter, Data logger etc.

(ii). Importance of Earthing The installation and maintenance of an effective low resistance earthing system is essential due to the following -

Efficiently dissipate heavy fault currents and electrical surges, both in magnitude and duration, to protect equipment being damaged so as to minimize down time, service interruption and replacement cost.

Provide a stable reference for electrical and RF circuits at the installation to minimize noise during normal operation.

Protection of personnel who work within the area from dangerous electric shock caused due to “step potential” or “touch potential”.

(iii). Characteristics of good Earthing system

Excellent electrical conductivity

Low resistance and electrical impedance.

Conductors of sufficient dimensions capable of withstanding high fault currents with no evidence of fusing or mechanical deterioration.

Lower earth resistance ensures that energy is dissipated into the ground in the safest possible manner.

Lower the earth circuit impedance, the more likely that high frequency lightning impulses will flow through the ground electrode path, in preference to any other path.

High corrosion resistance

The choice of the material for grounding conductors, electrodes and connections is vital as most of the grounding system will be buried in the earth mass for many years. Copper is by far the most common material used. In addition to its inherent high conductivity, copper is usually cathodic with respect to other metals in association with grounding sites, which means that it is less likely to corrode in most environments.

Mechanically robust and reliable. (iv) Location for Earth

Low lying areas close to the building or equipment are good for locating Earth Electrodes.

The location can be close to any existing water bodies or water points but not naturally well-drained.

Dry sand, lime stone, granite and any stony ground should be avoided.

Earthing electrode should not be installed on high bank or made-up soil. (v) Acceptable Earth Resistance value The acceptable Earth Resistance at earth busbar shall not be more than 1 ohm. (vi) Components of Earthing & Bonding system

The components of Earthing & Bonding system are- Earth electrode, Earth enhancement material, Earth pit, Equi-potential earth busbar, connecting cable & tape/strip and all other associated accessories.


61.1 Design of Earthing & Bonding system 61.1.1 Earth Electrode

The earth electrode shall be made of high tensile low carbon steel circular rods, molecularly bonded with copper on outer surface to meet the requirements of Underwriters Laboratories (UL) 467-2007 or latest. Such copper bonded steel cored rod is preferred due to its overall combination of strength, corrosion resistance, low resistance path to earth and cost effectiveness.

The earth electrode shall be UL listed and of minimum 17.0mm diameter and minimum 3.0mtrs. long.

The minimum copper bonding thickness shall be of 250 microns.

Marking: UL marking, Manufacturer’s name or trade name, length, diameter, catalogue number must be punched on every earth electrode.

Earth electrode can be visually inspected, checked for dimensions and thickness of copper coating using micron gauge. The suppliler shall arrange for such inspection at the time of supply, if so desired.

61.1.2 Earth Enhancement material

Earth enhancement material is a superior conductive material that improves earthing effectiveness, especially in areas of poor conductivity (rocky ground, areas of moisture variation, sandy soils etc.). It improves conductivity of the earth electrode and ground contact area. It shall have following characteristics-

shall mainly consist of Graphite and Portland cement. Bentonite content shall be negligible.

shall have high conductivity, improves earth’s absorbing power and humidity retention capability.

shall be non-corrosive in nature having low water solubility but highly hygroscopic.

shall have resistivity of less than 0.2 ohms-meter. Resistivity shall be tested by making a 20cm. cube of the material and checking resistance of the cube at the ends. The supplier shall arrange for such testing at the time of supply, if so desired. Necessary certificate from National/ International lab for the resistivity shall also be submitted.

shall be suitable for installation in dry form or in a slurry form.

shall not depend on the continuous presence of water to maintain its conductivity.

shall be permanent & maintenance free and in its “set form”, maintains constant earth resistance with time.

shall be thermally stable between -100 C to +600 C ambient temperatures.

shall not dissolve, decompose or leach out with time.

shall not require periodic charging treatment nor replacement and maintenance.

shall be suitable for any kind of electrode and all kinds of soils of different resistivity.

shall not pollute the soil or local water table and meets environmental friendly requirements for landfill.

shall not be explosive.

shall not cause burns, irritation to eye, skin etc.

Marking: The Earth enhancement material shall be supplied in sealed, moisture proof bags. These bags shall be marked with Manufacturer’s name or trade name, quantity etc.

61.1.3 Backfill material The excavated soil is suitable as a backfill but should be sieved to remove any

large stones and placed around the electrode taking care to ensure that it is well compacted. Material like sand, salt, coke breeze, cinders and ash shall not be used because of its acidic and corrosive nature.


61.1.4 Earth Pit As per the drawing enclosed 61.1.5 Construction of unit earth pit:

Refer typical installation drawing no. SDO/RDSO/E&B/001.

A hole of 100mm to 125mm dia shall be augured /dug to a depth of about 2.8 meters.

The earth electrode shall be placed into this hole.

It will be penetrated into the soil by gently driving on the top of the rod. Here natural soil is assumed to be available at the bottom of the electrode so that min. 150 mm of the electrode shall be inserted in the natural soil.

Earth enhancement material (minimum approx. 30-35 kg) shall be filled into the augured/dug hole in slurry form and allowed to set. After the material gets set, the diameter of the composite structure (earth electrode + earth enhancement material) shall be of minimum 100mm dia covering entire length of the hole.

Remaining portion of the hole shall be covered by backfill soil, which is taken out during auguring /digging.

A copper strip of 150mmX25mmX6mm shall be exothermically welded to main earth electrode for taking the connection to the main equi-potential earth busbar in the equipment room and to other earth pits, if any.

Exothermic weld material shall be UL listed and tested as per provisions of IEEE 837 by NABL/ ILAC member labs.

The main earth pit shall be located as near to the main equi-potential earth busbar in the equipment room as possible.

61.1.6 Construction of loop Earth by providing multiple earth pits

At certain locations, it may not be possible to achieve earth resistance of ≤1ohm with one earth electrode /pit due to higher soil resistivity. In such cases, provision of loop earth consisting of more than one earth pit shall be done. The number of pits required shall be decided based on the resistance achieved for the earth pits already installed. The procedure mentioned above for one earth pit shall be repeated for other earth pits.

The distance between two successive earth electrodes shall be min. 3mtrs. and max. upto twice the length of the earth electrode i.e. 6 mtrs. approx.

These earth pits shall then be inter linked using 25X2 mm. copper tape to form a loop using exothermic welding technique.

The interconnecting tape shall be buried at depth not less than 500mm below the ground level. This interconnecting tape shall also be covered with earth enhancing compound.

61.1.7 Measurement of Earth resistance

The earth resistance shall be measured at the Main Equi-potential Earth Busbar (MEEB) with all the earth pits interconnected using Fall of Potential method as per para 37 of IS: 3043.

61.1.8 Inspection Chamber

A 300X300X300 mm (inside dimension) concrete box with smooth cement plaster finish shall be provided on the top of the pit. A concrete lid, painted black, approx. 50 mm. thick with pulling hooks, shall be provided to cover the earth pit.

Care shall be taken regarding level of the floor surrounding the earth so that the connector is not too deep in the masonry or projecting out of it.

On backside of the cover, date of the testing and average resistance value shall be written with yellow paint on black background.


61.1.9 Equipotential Earth Busbar and its connection to equipments & Surge protection devices in the Equipment room: Refer typical bonding connections drawing no.SDO/RDSO/E&B/002.
