the work is in progress, the Contractor shall provided and use warning and / or traffic signs / lights or lanterns, barricades, fencing, watchman, etc. 2.1.5 Extra Depth and Clearance: At points where the contour of the earth may require extra depth according to customary good pipeline practice, or where a deep trench is required at the approaches to crossings of roadways, sewer line, Contractor shall excavate such additional depth as may necessary after obtaining permission from the EIC. Contractor shall excavate to additional depth as directed by the Engineer-In-Charge, where the pipeline approaches and crosses other pipelines, sewers, drain pipes, telephone conduits and other underground structures and specific low lying area so that the pipeline may be laid with at least 50 centimeters free clearance from the obstacle or as specified in the drawings, or such greater minimum distances as may be required. No pipeline shall be laid so as to be in contact with any electrical supply line, telegraph line, drain, sewer or connection work. Where the pipeline crosses areas, whose basement specifically require greater than normal depths of cover the trench shall be excavated to extra depth in accordance with the Right of Way agreement or as required. Contractor shall excavate all such additional depths to maintain the depth of earth cushion beyond 1.20 mtr as may be necessary for satisfactory completion of the work. Clearance on one side or the other of any interfering structures shall be determined on the field in accordance with the circumstances of each case with the provision that the line shall be laid as directed by the Engineer- In-Charge. Temporary under passing supports and other protective devices necessary to keep interfering structures unaffected, shall be provided by the Contractor and shall be of such design so as to ensure against their possible failure. 2.1.6 Finish of Trench: The employer intends that there shall be a minimum of hand guarding of the trench bottom However, to achieve this, Contractor shall have to dig as square a bottom of the trench as possible with the equipment. This in part can be obtained by adjusting and adopting the crumbling shoe and digging teeth of the trenching machines and by use of a drag behind the trenching machines. Contractor shall do hand work in the trench if necessary to free the bottom of the trench from loose rock and hard soil and to trim protruding roots from the bottom and side walls of the trench. However, the Contractor has the liberty to adopt any procedure according to site condition with due approval of the Engineer-In-Charge. Trench compactor should be used to compact the bed. 2.1.7 Padding: In all cases where rock or gravel is encountered in the bottom of trench, trench padding shall be provided to safeguard the pipe coating. The extent of trench padding (length) shall be decided by the Engineer-In-Charge. The thickness of the compacted padding shall not be less than 150 mm. In those areas that are to be padded the trench shall be at least 150 mm deeper than otherwise required, and evenly and sufficiently padded to keep the pipe, when in place at least 150 mm above the bottom of excavated trench. Padding materials shall be sand containing no gravel, rock, or lumps of hard soil. 2.1.8 Protection of Trench: Contractor shall keep the trench in good conditions until the pipe is laid. All type of safety measures for excavation work shall be taken and maintained as required. The Contractor shall provide, install and operate all the necessary pumping machineries, piping appliances and equipments and supply fuel, etc. to keep trench reasonably free from any water during excavation. 2.1.9 Protection Of Underground Utilities: Contractor shall obtain plans and full details of all existing and planed underground services from the EIC and shall follow plans & co-ordinates closely at all time during the performance of work. Contractor shall be responsible for action and protection of all underground lines and structures. In special locations, the use of trenching machine / backhoe may result in damage of property and subsurface structures likely to be encountered during excavation. At such places, Contractor shall excavate the trench manually to same specifications. Where the pipeline crosses other underground utilities / structures, Contractor shall first manually excavate to a depth the utilities / structures are located. Temporary underpinning, or any other type of supports and other protective devices necessary to keep the interfering structure intact shall be provided by Contractor to ensure against their possible failure. In locations, where the pipeline has to be laid more or less parallel to an existing pipeline, cable and / or other utilities in the right of way Contractor shall perform the work to the satisfaction of the Authority of the existing pipeline / cable / utility. In such locations Contractor shall perform work in such way that even under 86
the worst weather and flooding conditions, the existing pipeline / utilities remain stable and shall neither become undermined nor have the tendency to slide towards the trench. 2.1.10 Shifting of Underground Services: Any or all the existing underground utility lines such as telephone cables etc. which may be encountered during the progress of work shall have to be very carefully supported and maintained. In case any of the existing utility lines is to be shifted or attended in any fashion the Contractor shall intimate the Department. The Contractor shall also get the necessary alteration done by negotiation with the concerned organization to the satisfaction of the Engineer-in-Charge. No attempt should be made on the part of the Contractor to shift or alter any of the utility lines without specific instruction from Engineer-in-Charge. 2.1.11 Precautions Against Floatation: Contractor shall check if up-floating danger is present in open trench and then shall take appropriate measures to prevent up floating. Such as applying soil dams and de-watering of trench or temporary filling of water into the line (in exceptional cases). In some stretches, if up floating of the pipeline after back filing is reckoned with, such stretches shall be indicated in the drawings. If such stretches requiring negative buoyancy are encountered during construction, which are not indicated in drawing but required in the opinion of the Engineer-In-Charge, Contractor shall provide necessary measures to prevent buoyant effect in consultation with Engineer-In-Charge. Floating of the pipeline can be prevented by providing sufficient overburden or by providing sufficient dead weight by means of anchor block or by applying a continuous concrete coating around the pipe to provide the desired weight. Whatever continuous concrete coating is used, it shall conform to the provision of relevant specifications unless indicated otherwise in the drawing. 2.1.12 Night Caps: At the end of each day’s work or every time when joining operations are interrupted, the open ends of pipes shall be capped with securely closed metal cap or plug as approved by the Engineer-In-Charge so as to prevent the entry of dirt, dust, water or any foreign matter into the pipeline. These covers shall not be removed until the work is to be resumed. 2.1.13 Closing Lengths: Pipes which are required to be cut to from closing pieces in any portion of the pipelines or to terminate in chambers / manhole or other parts of the works shall not be cut until after all adjacent pipes and fitting have been installed and joined. The Contractor shall determine the length of each closing piece, the required angle and shape of the same, which shall be brought to the notice of the Engineer-In-Charge for approval. The cut shall be neatly performed and the end of the pipe shaped and trimmed so as to ensure an accurate joint or termination as the case may be any damage to sheathing, coating or lining shall be made good. 2.2 Laying of D.I.

All pipes, fittings, and valves shall be carefully lowered into the trench, piece by means of crane derrick, rope or other suitable tools or equipment, in such a manner as to prevent damage to pipes, valves, fittings, etc. and protective coatings and linings. Under no circumstances shall materials be dropped or dumped into the trench. If damage occurs to any pipe, fitting, valve or accessory in handling, the damage shall be immediately brought to the Engineer-In-Charge’s attention. The Engineer-In-Charge shall prescribe corrective repairs or rejection of the damaged items. Pipes over 250 mm diameter shall be handled and lowered into trenches with the help of crane. 2.2.2 Cleaning of D.I. Pipes and Fitting: All lumps, blisters, and excess coating material shall be removed from the socket and spigot end of each pipe. The outside of the spigot and inside of the socket shall be wiped clean. Dry and free from oil and grease before the D.I. pipe is laid. 2.2.3 Laying: 87
