Sector 29 (part), 30, 36 & 37 (part) is arguably the most rapidly developing area within Jaipur city with a multitude of high rise buildings. Presently the skeletal system of supply relies on tube wells with rapidly depleting discharges and poor water quality due to over exploitation. The proposed project is intended to solve the problem of water supply in the approximately 34 sq km area on long term basis using surface water supplies from Bisalpur Dam. At present there is no water supply system in place for the occupants of such areas, major institutions and effluent residents have their private tube-wells drawing ground water. Residents are meeting their water supply requirements through conventional sources like hand pumps/tube wells/open wells constructed for irrigation. Owing to limited surface water availability from Bisalpur Dam extension of water supply to such unconnected parts of Jaipur city could not be attempted and major part of urban population is without planned water supply system. The proposal is to provide good potable water on continuous basis to project area for its projected population for 2051, to solve the problem of water supply in the approximately 36.65 sq km area on long term basis using surface water supplies from Bisalpur Dam. At present there is no water supply system in place for the occupants of such areas, major institutions and residents have their private tube-wells drawing ground water. Residents are meeting their water supply requirements through conventional sources like hand pumps/tube wells/open wells constructed for irrigation. Bisalpur Water from Jawahar Circle Pumping Station of BJWSP, will be transferred to different headworks via tapping from transfer main presently laid to serve upto KhoNagorian and enroute areas and supplied through Zonal Service Reservoirs. Distribution system is designed on zonal basis and will be extended to uncovered areas. M/S IPE Global vide Work Order No. EE/PH/CD-I/Ar-II/2013-14/1831 dated: 27.06.2013, as a part of contract the firm has submitted the distribution system network design, and Project Report. The Distribution System is designed as per the latest guidelines of CPHEEO (keeping minimum size as 100 mm) and Pipe policy of PHED with pipelines on both side of wider roads, keeping provisions of DMAs and sub-DMAs. Design period of Water supply project is adopted as per recommended by CPHEEO manual. Per capita water consumption of 135 LPCD is adopted. Water Supply Duration Piped water supplied is designed on continuous 24 hour basis to distribute water to consumers at adequate pressure at all points. It is proposed to provide the distribution network based on DMA and as such, the whole project area is suitably divided in 11 number of distribution zones which are surrounded by a ring main making a closed loop. The Ring mains will be linked by supply pipes from all the SR’s within the Distribution Zone. It is proposed to develop DMA’s and the subsequent branched water distribution by withdrawing water from the ring main system. This system is a modification of circular or grid iron supply system. In this system, a closed ring, either rectangular or circular of the main pipes with interconnections at different locations, is formed around the area to be served. The ring Page | 85

Part-II Section-V: Requirement

system is suitable for towns & cities having well planned roads and helps in reducing pressure variations as well as leads to lower pipe diameters and hence economy in distribution system costs. However, a major drawback of the system is locating leaks and contamination points within the system. This distribution area is proposed to be further divided into a number of suitable District metering Areas (DMA) which are fed by this ring main. The system has been designed with provision of water demand of all area within the Project. The pipelines are proposed on existing road networks and provision for present open area where internal roads are not present, demand at nearby nodes have been provisioned. The Distribution Zones are to be fed with OHSRs of designed capacity. OHSRs for Distribution Zone nos 1 - 8 were already sanctioned in the part I of the Project (Total 10 No of OHSRs proposed under Package 3, work in advance stage), due to absence of clear land possession for OHSRs in the Zone No 9,10& 11 it was proposed to take up OHSR construction work in the Part II of the project. While preparing the DPR of Part II, provision for OHSRs of Zone no 9-11 was also missed inadvertently, and cost provision for Distribution Pipelines was proposed. The Distribution Design for Zone no 9-11 has been finalized with proposed OHSR location at JDA Teelawala Scheme for Zone 9 and JDA PHE Campus Mahal Scheme for Zone 10 & 11. Sufficient land is available at these two locations for construction of OHSRs. The proposed scope of Part II is therefore, now stated for providing, laying and jointing of Distribution Pipelines, in Zone no 1-11, construction of OHSRs of 1200 KL for Zone 9 and 1000 KL for Zone 10 & 11 and necessary SCADA related works. 1.4.1 Area Proposed in Phase-I (under the scope of this bid document): The Area covering JDA Sector 29, 30 & Pratap Nagar side is to be executed in Ist Phase. JDA Sector 29(part) and sector 30 has gained sizeable urban development in past few years. 1.5 Principle / Departmental Policy for Distribution System: The distribution system network will be laid as per the latest guidelines of CPHEEO (keeping minimum size as 100 mm) and Pipe policy of PHED with pipelines on both-side of wider roads. The detailed distribution system for each zone shall be designed keeping provisions of DMAs and sub-DMAs.

1.6 Description of Area under Proposed Distribution Zones: The entire project area is divided into 11 distribution zones proposed to be provided with ring mains (not under the scope of this bid document) around it to provide water to enclosed DMAs. Off-takes shall be provided on the ring mains from which the contractor shall make the necessary inter-connection and start laying distribution pipelines. The details of these distribution zones are provided in table below:

Depth of Cover

2.9

On average the change in slope per km length shall not be more than 10 in number. The slopes shall be such that in normal conditions, the cover over the laid pipe is neither more than 1.5 meters nor less than 0.6 meters in exceptional conditions. In general, the cover should be 1.0 meter. However, the limitation for cover shall be as given in chapter ‘Specification of pipeline’. Pipe shall be laid on dressed; compacted/excavated land/ well dressed trenches along the alignment as per site conditions. 2.10 Thrust Blocks It is proposed to provide anchorage in the form of thrust blocks at each deflection in horizontal alignment of the pipeline which shall resist the unbalanced forces at such deflections by their weight. The vertical alignment of pipeline is proposed to be fixed in such a manner so than deflection in vertical alignment is restricted to 3-4 degrees which can be smoothened by accommodating in pipe joints and requirement for thrust blocks at such location can be avoided. • • • •

The thrust blocks are to be designed on following criteria/assumptions: The thrust blocks are to be designed for field test pressure in pipeline i.e. 1.5 times the designed working pressure of pipeline at that point. The minimum surface reinforcement in the blocks shall be 5 Kg/sqm as proposed in Manual. The Grade of Concrete shall be M15.

2.11 DMA Philosophy 2.11.1 Definition A DMA is defined as a discrete area of a distribution system usually created by the closure of valves or complete disconnection of pipe work in which the quantities of water entering and leaving the area are metered. The flow is analysed to quantify the level of leakage. In this way the leakage practitioner can determine more precisely where and when it is most beneficial to undertake leak location identification activities. 2.11.2 DMA Design •

The factors taken into account when designing a DMA are:



The required economic level of leakage;



Size (geographical area and number customer connections);



Housing type i.e. blocks of flats or single family occupancy housing;



Variation in ground level;



Water quality considerations;



Pressure requirements;



Fire fighting capacity;



Target final leakage level;



Number of valves to be closed; Page | 95

Part-II Section-V: Requirement

NIT No.1/2018-19 Bisalpur Jagatpura WSS (Distribution-Phase-I)



Number of meters used to monitor flow ideally minimised;



Large metered customers should have their meters measured as export meters from the DMA.

Infrastructure condition The over-riding factor is to successfully create the DMAs without significantly affecting the quality of service to the customers. This is particularly important in networks where the existing operating pressures are already low. It should also be remembered that the reduction in leakage that the creation of DMAs allows will also tend to increase the operational pressures within the network. A DMA boundary should not necessarily be considered definitive. With the change in operating conditions, it might be necessary to modify the boundary. For this reason it is usually better to create a boundary by closing valves rather than cutting the pipes. However care must be taken to ensure that these valves are leak tight and that their accidental opening is avoided. 2.11.3 DMA Size & Economics The size of DMAs has an impact on the cost of creating them: the smaller the DMAs, the higher the cost. This is because more valves and flow meters will be required. The maintenance at a later date will also tend be more costly. However the benefits of smaller DMAs are: New leaks will be identified earlier reducing "awareness time"; Smaller leaks can be identified against the “noise” of night use; The location times can be reduced because it is quicker to carry out detection in smaller DMAs to find a given leak than a large one; Detection costs will be reduced because less of the network needs to be searched to find a given number of leaks. This all allows a lower leakage level to be maintained. Consequently, DMAs in urban areas vary between 500 and 3000 properties. It has been found that if a DMA is larger than 5000 properties, it becomes difficult to discriminate small bursts (e.g. service pipe bursts) from night flow data, and burst location takes longer. However, large DMAs can be divided into smaller temporary DMAs by closing additional valves so that each subarea is fed in turn through the DMA meter for leak detection activities. In this case, any extra valves required should be taken into account at the DMA design stage. In networks with very poor infrastructure condition the high burst frequency (and the pressure increases after repairs that lead to further bursts) make it worthwhile having very small DMAs: less than 500 customer connections. Alternatively DMAs can be sized by km of pipe work, particularly in systems that contain blocks of flats which tend to have a very low connection density. This has the additional advantage of being easily referenced to the leakage location activity which is normally quantified in terms of the length of mains. Page | 96

Part-II Section-V: Requirement

NIT No.1/2018-19 Bisalpur Jagatpura WSS (Distribution-Phase-I)

In general, hydraulic, practical and economic factors will ultimately determine the size of the DMAs. 2.11.4 Proposed DMAs The zonal distribution system is sub divided into number of DMAs. Each DMA is proposed to be fed from ring main through a single inlet point. All the DMAs are isolated from each other with no interconnections between them. TABLE 2:4:ZONE WISE DMA SUMMARY

Should slips occur, the slipped material shall be removed and the slope dressed to a modified stable slope. --= FUCK YOU, DON'T TRY WITH US =-- Excavation for Laying Pipe along the Road

While laying the pipeline below ground along the road side, the contractor shall observe the following: The contractor shall not be allowed to take earth from the burrow pits if excavation required to take additional earth results in side slopes steeper than 1:1 in clay dominating soil and 1:1.5 in case of silty sand or sandy soils. If invert of pipe is kept above the existing burrow pit level or part of pipe is above it, the minimum side slopes of 1:1 in clay dominating soil and 1:1.5 in case of silty sand or sandy soils shall be provided on the side towards the burrow pit area so as to provide required cover. The side slopes shall be properly compacted upto 95% of Procter density. If earth is taken for providing required cover to pipe from the burrow pits, the burrow pits shall be so graded upto the nearest drain, that no impounding of water is possible in burrow pit area. If the pipeline is laid just near the road section, as far as practical minimum cover of 0.9 meter shall be ensured. Whenever this requirement of cover cannot be ensured, concrete casing of deigned thickness as per considerations given for design in this chapter shall be provided. --= FUCK YOU, DON'T TRY WITH US =-- Stripping Loose Rock

All loose boulders, detached rocks partially and other loose material which might move therewith not directly in the excavation but so close to the area to be excavated as to be liable, in the opinion of Engineer in Charge, to fall or otherwise endanger the workmen, equipment, or the work shall be stripped off and removed from the area of the excavation. The method used shall be such as not to render unstable or unsafe the portion which was originally sound and safe. Any material not requiring removal in order to complete the permanent works, but which, in the opinion of Engineer in Charge, is likely to become loose or unstable later, shall also be promptly and satisfactorily removed. --= FUCK YOU, DON'T TRY WITH US =-- Timber Shoring

Wherever required close timbering shall be done by completely covering the sides of the trenches and pits generally with short, upright members called 'polling boards'. These shall be of minimum 25 cm x 4 cm sections or as approved by the Engineer in Charge. The boards shall generally be placed in position vertically side by side without any gap on each side of the excavation and shall be secured by horizontal walling of strong wood at maximum 1.2 metre spacing, strutted with ballies or as approved by the Engineer in Charge. The length of the ballie struts shall depend on the width of the trench or pit. If the soil is very soft and loose, the boards shall be placed horizontally against each side of the excavation and supported by vertical walling, which in turn shall be suitably strutted.

Timber shoring shall be 'close' or 'open' type, depending on the nature of soil and the depth of pit or trench. The type of timbering shall be as approved by the Engineer in Charge. It shall be the responsibility of the Contractor to take all necessary steps to prevent the sides of excavations, trenches, pits, etc. from collapsing. Timber shoring may also be required to keep the sides of excavations vertical to ensure safety of adjoining structures or to limit the slope of excavations, or due to space restrictions or for other reasons. Such shoring shall be carried out, except in an emergency, only under instructions from the Engineer in Charge. The withdrawal of the timber shall be done carefully to prevent the collapse of the pit or trench. It shall be started at one end and proceeded with, systematically to the other end. Concrete or masonry shall not be damaged during the removal of the timber. In the case of open timbering, the entire surface of the side of trench or pit is not required to be covered. The vertical boards of minimum 25 cm x 4 cm sections shall be spaced sufficiently apart to leave unsupported strips of maximum 50 cm average width. The detailed arrangement, sizes of the timber and the spacing shall be subject to the approval of the Engineer in Charge. In all other respects, the Employer’s Requirements for close timbering shall apply to open timbering. In case of large pits and open excavations, where shoring is required for securing safety of adjoining structures or for any other reasons and where the planking across sides of excavations/pits cannot be strutted against, suitable inclined struts supported on the excavated bed shall be provided. The load from such struts shall be suitably distributed on the bed to ensure no yielding of the strut. --= FUCK YOU, DON'T TRY WITH US =-- Dewatering

The Contractor shall ensure that the excavation and the structures are free from water during construction and shall take all necessary precautions and measures to exclude ground/rain water so as to enable the works to be carried out in reasonably dry conditions in accordance with the construction programme. Sumps made for dewatering must be kept clear of the excavations/trenches required for further work. The method of pumping shall be approved by Engineer in Charge, but in any case, the pumping arrangement shall be such that there shall be no movement of subsoil or blowing in due to differential head of water during pumping. Pumping arrangements shall be adequate to ensure no delays in construction. The dewatering shall be continued for at least (7) seven days after the last pour of the concrete. The Contractor shall, however, ensure that no damage to the structure results on stopping of dewatering. The Contractor shall study the sub-soil conditions carefully and shall conduct any tests necessary at the site with the approval of the Engineer in Charge to test the permeability and drainage conditions of the sub-soil for excavation, concreting etc., below ground level. The scheme for dewatering and disposal of water shall be approved by the Engineer in Charge. The Contractor shall suitably divert the water obtained from dewatering from such areas of site where a build up of water in the opinion of the Engineer in Charge obstructs

the progress of the work, leads to insanitary conditions by stagnation, retards the speed of construction and is detrimental to the safety of men, materials, structures and equipment. When there is a continuous inflow of water and the quantum of water to be handled is considered in the opinion of Engineer in Charge, to be large, a well point system- single stage or multistage, shall be adopted. The Contractor shall submit to the Engineer in Charge, details of his well point system including the stages, the spacing, number and diameter of well points, headers etc., and the number, capacity and location of pumps for approval. --= FUCK YOU, DON'T TRY WITH US =-- Rain Water Drainage

Grading in the vicinity of excavation shall be such as to exclude rain/ surface water draining into excavated areas. Excavation shall be kept clean of rain and such water as the Contractor may be using for his work by suitably pumping out the same. The scheme for pumping and discharge of such water shall be approved by the Engineer in Charge. --= FUCK YOU, DON'T TRY WITH US =-- Fencing, Watching and Lightening

The posts of the fencing shall be of timber, securely fixed in the ground not more than 2.5 m. apart. They shall not be less than 10 cm in dia. or not less than 1.25 m above the surface of ground. There shall be two rails, one near the top of the posts and the other about 0.5 m above the ground and each shall be of 5 cm to 10 cm in dia. and sufficiently long to run from post to post which they shall be bound with strong ropes.

Safety precautions have to be incorporated in the work progress Hindrances to the public have to be minimized The trench shall not be allowed to erode The trench must not be filled with water. The trench must not be refilled before laying of the pipes. The bed for the laying of the pipes has to be prepared according to the l-section immediately before laying of the pipes. The trench excavation of pipe line shall be in accordance with IS 12288. pipe trenches shall be excavated to the lines and levels shown on the drawings or as directed by the Engineer. The depth of the excavated trench shall be as given in the drawings or as directed by the Engineer. The width of the trench at bottom between the faces of sheeting shall be such as to provide 200 / 150mm clearance on either side of the DI pipe except where rock excavation is involved. No pipe shall be laid in a trench until the section of trench in which the pipe is to be laid has been approved by the Engineer. The depth should be sufficient to provide a cover not less than 1000 mm so that the pipe line will not interfere with the cultivation of land. It may be necessary to increase the depth of pipeline to avoid land drains or in the vicinity of roadsor other crossing. Care should be taken to avoid the spoil bank causing an accumulation of rain water. The bottom of the trench shall be trimmed and leveled to permit even bedding of the pipes. It should be free from all extraneous matter which may damage the pipe or the pipe coating. Additional excavation shall be made at the joints of the pipes, so that he pipe is supported along its entire length. All excavated material shall be stacked in such a distance from the trench edge that it will not endanger the work or workmen and it will avoid obstructing footpaths, roads and drive ways. Hydrants under pressure, surface boxes, fire or other utility controls shall be left unobstructed and accessible during the construction work. Gutters shall be kept clear or other satisfactory provisions made for street drainage, and natural water – courses shall not be obstructed. To protect persons from injury and to avoid damage to property, adequate barricades, construction signs, torches, red lanterns and guards, as required, shall be placed and maintained during the progress of the work and until it is safe for traffic to use the roadways. All materials, piles equipment and pipes which may serve as obstruction to traffic shall be enclosed by fences or barricades and shall be protected by illuminating proper lights when the visibility is poor. As far as possible, the pipe line shall be laid below existing services, like water and gas pipes, cables, cable ducts and drains but not below sewers, which are usually laid at greater depth. Where it is unavoidable, pipe line should be suitably protected. A minimum clearance of 150 mm shall be provided between the pipe line and such other services. Trees, shrubbery fences, poles, and all other property and protected. Tree roots shall be cut within a distance of 50 cm prevent roots from entering them.

obstructions encountered in the progress of the work shall be provided. The structures, which will be disturbed shall be restored after completion of the work. Wherever necessary to prevent caving, trench excavations in soils such as sand, gravel and sandy soil shall be adequately sheeted and braced. Where sheeting and bracing are used, the net trench width after sheeting shall not be less than that specified above. The sides of the excavation shall be adequately supported at all times and, except where described as permitted under the Contract, shall be not battered. The Engineer in co-operation with the Contractor shall decide about the sheeting / bracing of the trench according to the soil conditions in a particular stretch and taking into account the safety requirements of the Contractor’s and Engineer – In – Charge’s staff. Generally, safety measures against caving have to be provided for trenches with vertical walls if they are deeper than 2.0 m. --= FUCK YOU, DON'T TRY WITH US =-- Trench Excavation to Commensurate With the Laying Progress: The work of trench excavation should be commensurate with laying and jointing of the pipe line. It should not be dug in advance for a length greater than 500 m ahead of work of laying and jointing of pipeline unless otherwise defined by the Engineer. The Contractor has to ensure the following: safety protections as mentioned above have to be incorporated in the work process hindrances to be public have to be minimized the trench must not be eroded before the pipes are laid the trench must not be filled with water when the pipes are laid the trench must not be refilled before laying of the pipes. The bed for the laying of the pipes has to be prepared according to the L-Section immediately before laying of the pipes.

3.3.14 Bedding of the Pipes: The DI pipeline shall generally be laid in ordinary sandy soil for which no extra bedding shall be provided. In such case, while doing the excavation, the bottom of the trench shall be prepared in a manner so as to match the curvature of the pipe as far as possible subtending an angle of about 120o at the center of pipe. Wherever the bottom of the trench is of such a nature (i.e. any type of rock / hard soil/ boulder) which is likely in the opinion of the Engineer-in-Charge to cause damage to the pipe or coating or an unsuitable material is encountered which cannot support the pipe, the contractor shall excavate the trench to an additional depth below the required depth and shall refill to required level with suitable material such as loose soil/ sand, to be approved by the Engineer-in-Charge. The bedding thickness shall be not less than 15 cm under the barrel of the pipes. The complete pipe has to be covered and surrounded by the same material as used for bedding so that a total cover of 30cm above the barrel can be achieved. The excavated hard/dense soil can be refilled after bedding and covering of the pipe with the loose soil/sand. The bedding shall be compacted with a light hand rammer. Adding sand during ramming shall make up any reduction in thickness due to compaction. For the purpose of the bedding under this item only screened fine sand of grain size not larger than 2mm shall be used. The sand shall be a clean, uncoated and free from

In no case shall sand containing more than 3.5 % by dry volume or 5% by wet volume of clay, loam or silt be accepted. Tests specified for determining silt in sand and organic impurities as described in IS:383 shall apply. Sieved and washed sand shall be stored on the works in such a manner as to prevent intrusion of any foreign matter, including coarser particles of sand or any clay or metal or chips. Tests as indicated above shall be performed if called for by the Engineer at the expense of the Contractor. 3.3.15 PIPE LYING BELOW GROUND The pipes will be cleaned in the whole length with special care of the spigot and sockets on the inside / outside to ensure that they are free from dirt and unwarranted projections. The whole of the pipes shall be placed in position singly and shall be laid true to profile and direction of slope indicated on longitudinal sections. The pipes shall be laid without deflection in a straight alignment between bends and between high and low points. Vertical and horizontal deflections between individual pipes need the approval of the Engineer. In no case the deflection shall be more than 75% of those recommended by the manufacturer. Before pipes are jointed they shall be thoroughly cleaned of all earth lumps, stones, or any other objects that may have entered the interior of the pipes, particularly the spigot end and the socket including the groove for the rubber ring. Pipes and the related specials shall be laid according to the instructions of the manufacturers and using the tools recommended by them. Cutting of pipes shall be reduced to a minimum required to conform with the drawings. Cutting has to be made with suitable tools and according to the recommendations of the manufacturer. The spigot end has to be chamfered again at the same angle as the original chamfered end. Cutting shall be perpendicular to the centre line of the pipe. In case of ductile iron pipes the cut and chamfered end shall be painted with two coats of epoxy paint. If there is no mark for the insertion depth on the spigot end of the (cut) pipe it shall be marked again according to the instructions of the manufacturer. Before pipes are jointed they shall be thoroughly cleaned off all earth lumps, stones, or any other objects that may have entered the interior of the pipes, particularly the spigot end and the socket including the groove for the rubber ring. End caps, if any, shall be removed only just before laying and jointing. The socket and spigot ends of the pipes shall be brushed and cleaned. The chamfered surface and the end of the spigot end has to be coated with a suitable lubricant recommended by the manufacturer of the pipes. Oil, petroleum bound oils, grease or other material which may damage the rubber gasket shall not be used as lubricant. The rubber gasket shall be inserted into the cleaned groove of the socket. It has to be checked for correct positioning. All specials like bends, tees etc. and appurtenances like sluice or butterfly valves etc. shall be laid in synchronization with the pipes. The Contractor has to ensure that the specials and accessories are ready in time to be installed together with the pipes. The designed Page | 143

Part-II Section-V: Requirement

anchorage shall be provided to resist the thrusts developed by internal pressure at bends, tees, etc. At the end of each working day and whenever work is interrupted for any period of time, the free ends of laid pipes shall be protected against the entry of dirt or other foreign matter by means of approved plugs or ends caps. When pipe laying is not in progress, the open ends of installed pipe shall be closed by approved means to prevent entrance of trench water and dirt into the line. No pipe shall be laid in wet trench conditions that preclude proper bedding, or when, in the opinion of the Engineer, the trench conditions or the weather are unsuitable for proper installation. The pipe line laid should be absolutely straight unless planned otherwise. The accuracy of alignment should be tested before starting refilling with the help of stretching a string between two ends of the straight stretch of pipes to rectify possible small links in laying. Pipes should be lowered into the trench with tackle suitable for the weight of pipes. For smaller sizes, up to 200mm nominal bore, the pipe may be lowered by the use of ropes but for heavier pipes suitable mechanical equipment have to used. On gradients of 1:15 or steeper, precautions should be taken to ensure that the spigot of the pipe being laid does not move into or out of the socket of the laid pipe during the jointing operations. As soon as the joint assembly has been completed, the pipe should be held firmly in position while the trench is back filled over the barrel of the pipe. Where a pipeline crosses a water course, the design and method of construction should take into account the characteristics of the water course to ascertain the nature of bed, scour levels, maximum velocities, high flood levels, seasonal variation, etc. which affect the design and laying of pipeline. The assembly of the pipes shall be made as recommended by the pipe manufacturer and using the suitable tools. The two pipes shall be aligned properly in the pipe trench and the spigot end shall be pushed axially into the socket either manually or with a suitable tool specially designed for the assembly of pipes and as recommended by the manufacturer. The spigot has to be inserted up to the insertion mark on the pipe spigot. After insertion, the correct position of the socket has to be tested with a feeler blade. --= FUCK YOU, DON'T TRY WITH US =-- STRINGING OF PIPES ALONG THE ALIGNMENT

The pipes shall be laid out properly along the proposed alignment in a manner that they do not create any significant hindrance to the public and that they are not damaged. Stringing of the pipes end to end along the working width should be done in such a manner that the least interference is caused in the land crossed. Gaps should be left at intervals to permit the passing of equipment across the working area. Pipes shall be laid out that they remain safe where placed and that no damage can occur to the pipes and the coating until incorporated in the pipeline. If necessary, pies shall be wedged to prevent accidental movement. Precautions shall be made to prevent excessive soil, mud etc. entering the pipe.

Generally, the pipes shall be laid within two weeks from the date of their dispatch from the manufacturer / store. 3.3.16 LAYING AND JOINTING OF DI PIPES Pipes should be lowered into the trench with tackle suitable for the weight of pipes. For smaller sizes, up to 200mm nominal bore, the pipe may be lowered by the use of ropes but for heavier pipes suitable mechanical equipment have to used. All construction debris should be cleared from the inside of the pipe either before or just after a joint is made. This is done by passing a pull-through in the pipe, or by hand, depending on the size of the pipe. All persons should vacate any section of trench into which the pipe is being lowered. On gradients of 1:15 or steeper, precautions should be taken to ensure that the spigot of the pipe being laid does not move into or out of the socket of the laid pipe during the jointing operations. As soon as the joint assembly has been completed, the pipe should be held firmly in position while the trench is back filled over the barrel of the pipe. The designed anchorage shall be provided to resist the thrusts developed by internal pressure at bends, tees, etc. Where a pipeline crosses a water course, the design and method of construction should take into account the characteristics of the water course to ascertain the nature of bed, scour levels, maximum velocities, high flood levels, seasonal variation, etc. which affect the design and laying of pipeline. The pipe shall be laid accordingly with adequate protection. The assembly of the pipes shall be made as recommended by the pipe manufacturer and using the suitable tools. The socket and spigot ends of the pipes shall be brushed and cleaned. The chamfered surface and the end of the spigot end have to be coated with a suitable lubricant recommended by the manufacturer of the pipes. Oil, petroleum bound oils, grease or other material, which may damage the rubber gasket, shall not be used as lubricant. The rubber gasket shall be inserted into the cleaned groove of the socket. It has to be checked for correct positioning. The two pipes shall be aligned properly in the pipe trench and the spigot end shall be pushed axially into the socket either manually or with a suitable tool specially designed for the assembly of pipes and as recommended by the manufacturer. The spigot has to be inserted up to the insertion mark on the pipe spigot. After insertion, the correct position of the socket has to be tested with a feeler blade. Deflection of the pipes –if any- shall be made only after they have fully been assembled. The deflection shall not exceed 75% of the values indicated by the pipe manufacturer. --= FUCK YOU, DON'T TRY WITH US =-- PRECAUTIONS AGAINST FLOATATION

When the pipeline laid underground or above ground in a long narrow cutting gets submerged in water collected in the trench of cutting it is subjected to an uplift pressure due to buoyancy and is likely to float if completely or partly empty. In the design of pipelines, provision is to be made to safeguard against floatation providing sufficient overburden or by providing sufficient dead weight by means of blocks, etc. Pipe shall be Page | 145

Part-II Section-V: Requirement

provided against floatation by providing anchor blocks. Factor of safety for calculations for check against floating shall be taken as 1.5. In the case of works extending over one or more monsoon seasons, however, special care and precautions are necessary during the progress of work on this account. The Contractor shall close down pipe laying operations well in time for the monsoon. The work of providing blocks, refilling the earth to the required level, compacting the same, etc. shall always be done as soon as the pipeline in the cutting has been laid. The Contractor shall see that the water shall not be allowed to accumulate in open trenches. Where work is in an incomplete stage, precautionary work, such as blank-flanging in the open ends of the pipeline and filling the pipeline with water etc. shall be taken up as directed by the Engineer. Such works shall be to the Contractor's account and no separate payment shall be made for the same. The Contractor's rate for pipe laying shall be deemed to include such precautionary measures against floatation. Protection of the pipeline against floatation during the Contract Period shall be the responsibility of the Contractor. Should any section of the pipeline float due to his negligence, etc. the entire cost of laying it again to the correct line and level shall be to his account. --= FUCK YOU, DON'T TRY WITH US =-- FILL, BACKFILLING AND SITE GRADING

Trenches shall be backfilled with approved selected excavated material only after the successful testing of the pipeline. The tamping around the pipe shall be done by hand or other hand operated mechanical means. The water content of the soil shall be as near the optimum moisture content as possible. Filling of the trench shall be carried out simultaneously on both sides of the pipe in such a manner that unequal pressure does not occur.. Each layer shall be consolidated by watering, ramming, care being taken to avoid damage to the pipeline. 3.3.17 Fill, Backfilling --= FUCK YOU, DON'T TRY WITH US =-- General

All fill material shall be subject to the Engineer in Charge’s approval. If any material is rejected by Engineer in Charge, the Contractor shall remove the same forthwith from the site.

On completion of the pipe laying operations in any section, for a length of about 100m and while further work is still in progress, refilling of trenches shall be started by the Contractor with a view of restricting the length of open trenches. Pipe laying shall closely follow the progress of Trench Excavation and the Contractor shall not permit unreasonably excessive lengths of trench excavation to remain open while awaiting testing of the pipeline. If the Engineer considers that the Contractor is not complying with any of the foregoing requirements, he may prohibit further trench excavation until he is satisfied with the progress of laying and testing of pipes and refilling of trenches. Only soft earth and murrum of good quality free from stones boulders, roots, vegetation etc., shall be utilised after the lumps are broken for filling in around the pipes for atleast 30cm all around for pipes. Filling shall be done in layers not exceeding 150mm and compacted to 70 to 80% of max. dry density percent of the maximum dry density as per part VII of IS:2720. The excavated material nearest to the trench shall be used first. Care shall be taken during backfilling, not to injure or disturb the pipes, joints or coating. Filling shall be carried out simultaneously on both sides of the pipes so that unequal pressure does not occur. Walking or working on the completed pipeline shall not be allowed unless the trench has been filled to height of atleast 30cm over the top of the pipe except as may be necessary for tamping etc., during backfilling work. The remaining portion of the trench may be filled in with a mixture of hard and soft material free from boulders and clods of earth larger than 150mm in size if sufficient quantity of good earth and murrum are not available. Filling in shall be done in layers not exceeding 225mm in thickness accompanied by adequate, ramming etc., so as to be compacted to 70 to 80% of the maximum dry density as per part VII of IS:2720.

Before pipes are jointed they shall be thoroughly cleaned of all earth lumps, stones, or any other objects that may have entered the interior of the pipes, particularly the spigot end and the socket including the groove for the rubber ring. End caps are removed only just before laying and jointing All specials like bends, tees etc. and appurtenances like sluice or butterfly valves etc. shall be laid in synchronization with the pipes. The Contractor has to ensure that the specials and accessories are ready in time to be installed together with the pipes. At the end of each working day and whenever work is interrupted for any period of time, the free ends of laid pipes shall be protected against the entry of dirt or other foreign matter by means of approved plugs or endcaps. When pipe laying is not in progress, the open ends of installed pipe shall be closed by approved means to prevent entrance of trench water and dirt into the line. No pipe shall be laid in wet trench conditions that preclude proper bedding, or when, in the opinion of the Engineer in Charge, the trench conditions or the weather are unsuit- able for proper installation.

The laying of pipes shall be as per the provisions relevant IS, however the specific references given herein shall prevail on the provisions of the standards. Pipes should be lowered into the trench with tackle suitable for the weight of pipes. For smaller sizes, up to 200 mm nominal bore, the pipe may be lowered by the use of ropes but for heavier pipes suitable mechanical equipment have to be used. All construction debris should be cleared from the inside of the pipe either before or just after a joint is made. This is done by passing a pull-through in the pipe, or by hand, depending on the size of the pipe. All persons should vacate any section of trench into which the pipe is being lowered. On gradients of 1:15 or steeper, precautions should be taken to ensure that the spigot of the pipe being laid does not move into or out of the socket of the laid pipe during the jointing operations. As soon as the joint assembly has been completed, the pipe should be held firmly while the trench is back filled over the barrel of the pipe. Suitable transverse anchors shall be provided in sloping reaches as defined hereinafter. The designed anchorage shall be provided to resist the thrusts developed by internal pressure at bends, tees, etc. Where a pipeline crosses a watercourse, the design and method of construction should take into account the characteristics of the watercourse to ascertain the nature of bed, scour levels, maximum velocities, high flood levels, seasonal variation, etc. which affect the design and laying of pipeline. The pipe shall be laid accordingly with adequate protection. The pipes in such cases shall be laid below ground with anchor blocks of suitable size and design. The socket and spigot ends/other ends of the pipes shall be brushed and cleaned. The chamfered surface and the end of the spigot end has to be coated with a suitable lubricant recommended by the manufacturer of the pipes. Oil, petroleum bound oils, grease or other material which may damage the rubber gasket shall not be used as lubricant. The rubber gasket shall be inserted into the cleaned groove of the socket. It has to be checked for correct positioning. The two pipes shall be aligned properly in the pipe trench and the spigot end shall be pushed axially into the socket either manually or with a suitable tool specially designed for the assembly of pipes and as recommended by the manufacturer. The spigot has to be inserted up to the insertion mark on the pipe spigot.

Wherever the bottom of the trench is of such a nature (i.e. hard rock/decomposed rock/ boulder) which is likely to cause damage to the pipe or coating or an unsuitable material is encountered which cannot support the pipe, the contractor shall excavate the trench to an additional depth below the required depth and shall refill to required level with stone/ gravel free soil. The bedding thickness shall be not less than 20 cm under the barrel of the pipes having size 400mm and above whereas it should not be less than 15cm for pipes of size up to 350mm. The complete pipe has to be covered and surrounded by the same material as used for bedding so that a total cover of 30cm above the barrel can be achieved. The excavated material can be refilled after bedding and covering of the pipe with the river sand screened at source or crusher dust approved by EiC. No un screened sand shall be dumped at site of pipeline. The bedding shall be compacted with a light hand rammer. Any reduction in thickness due to compaction shall be made up by adding sand during ramming.. The earth shall be clean, uncoated and free form clay lumps, injurious amounts of dust, soft particles, organic matter, loam or other deleterious substances. --= FUCK YOU, DON'T TRY WITH US =-- Transverse Anchors

Pipes on slopes need be anchored when there the backfill around the pipe is likely to slide away or washed out due to run off in case of rains and thereby carrying the pipe with it. Generally for slopes up to 30º and in very good drained soil, carefully tamped in layers of 100 mm under and over the pipe, right up to the top of the trench will not require anchoring. For steeper slopes, one out of every three pipe shall be held by straps fastened to vertical support anchored in concrete. Minimum two supports one at the top and other at the bottom of slope shall invariably be provided when the slope is more than those definedbelow.

xiv)

3. For underwater concreting the quantity of coarse aggregate, either by volume or mass, shall not be less than 1.5 times nor more than twice that of the fine aggregate.

4.4.9 Mixing Concrete shall be mixed in a mechanical mixer conforming to IS 1791. The mixing shall be continued until there is uniform distribution of materials and the mass is uniform in colour and consistency. If there is segregation after unloading, the concrete should be remixed. 4.4.10 Form work Formwork shall be all inclusive and shall consist of but not be limited to shores, bracings, sides of footings, walls, beams and columns, bottom of slabs etc. including ties, anchors, hangers, inserts, false work, wedges etc. The design and engineering of the formwork as well as its construction shall the responsibility of the Contractor, However, if so desired by the EIC, the drawings and calculations for the design of the formwork shall be submitted to the EIC for the approval.

Capable of being cleaned and/or coated if necessary immediately prior to casting the concrete; design temporary openings where necessary for these purposes and to facilitate and the preparation of construction joints. The formwork may be of timber, plywood, steel, plastic or concrete depending upon the type of finish specified. Sliding forms and slip form may be used with the approval of the EIC. Timber for formwork shall be well seasoned, free from sap, shakes, loose knots, worm holes, warps and other surface defects. Joints between formwork and structures shall be sufficiently tight to prevent loss of slurry from concrete, using seals if necessary. The faces of formwork coming in contact with concrete shall be cleaned and two coats of approved mould oil applied before fixing reinforcement. All rubbish, particularly chippings, shavings, sawdust, wire pieces dust. etc. shall be removed from the interior of the forms before the concrete is placed. Where directed, cleaning of forms shall be done by blasting with a jet of compressed air at no extra cost. Forms intended for reuse shall be treated with care. Forms that have deteriorated shall not be used. Before reuse, all forms shall be thoroughly scraped, cleaned, nails removed, holes suitably plugged, joints repaired and warped lumber replaced to the satisfaction of the EIC. The Contractor shall equip himself with enough shuttering to allow for wastage so as to complete the job in time. Permanent formwork shall be checked for its durability and compatibility with adjoining concrete before it is used in the structure. It shall be properly anchored to the concrete. Wire ties passing through beams, columns and walls shall not be allowed. In their place bolts passing through sleeves shall be used. Formwork spacers left in-situ shall not impair the desired appearance or durability of the structure by causing spalling, rust staining or allowing the passage of moisture. For liquid retaining structures, sleeves shall not be provided for through bolts nor shall through bolts be removed if provided. The bolts, in the latter case, shall be cut at 25 mm depth from the surface and the hole made good by cement mortar of the same proportion as the concrete just after striking the formwork. Where specified all corners and angles exposed in the finished structure shall have chamfers or fillets of 20 mm x 20 mm size. Forms for substructure may be omitted when, in the opinion of the EIC, the open excavation is firm enough (in hard non-porous soils) to act as a form. Such excavations shall be larger, as approved by the EIC, than that required as per drawing to compensate for irregularities in excavation. The Contractor shall provide adequate props carried down to a firm bearing without overloading any of the structures. The shuttering for beams and slabs shall be so erected that the side shuttering of beams can be removed without disturbing the bottom shuttering. If the shuttering for a column is erected for the full height of the column, one side shall be built up in sections as placing of concrete proceeds or windows left for placing concrete from the side to limit the drop of concrete to 1.0 m or as approved by the EIC. The Contractor shall temporarily and securely

fix items to be cast (embedments/ inserts) in a manner that will not hinder the striking of forms or permit loss of grout. Formwork showing excessive distortion, during any stage of construction, shall be repositioned and strengthened. Placed concrete affected by faulty formwork, shall be entirely removed and formwork corrected prior to placement of new concrete at Contractor’s cost. 4.4.11 Preparation Prior to Concrete Placement Before concrete is actually placed in position, the inside of the formwork shall be cleaned and mould oil applied, inserts and reinforcement shall be correctly positioned and securely held, necessary openings, pockets, etc. provided. All arrangements- formwork, equipment and proposed procedure, shall be approved by the EIC. Contractor shall maintain separate Pour Card for each pour as per the format enclosed. 4.4.12 Check for Reinforcement and concreting All reinforcement shall be checked and recorded prior to pouring of concrete by an authorised representative of the engineer in Charge. Similarly the entire concrete pouring work shall be done in the presence of authorised representative. The contractor shall therefore give a notice of a minimum three days to the engineer in Charge or his representative such that the works can be checked by him or his authorised representative. 4.4.13 Transporting, Placing and Compacting Concrete Concrete shall be transported from the mixing plant to the formwork with minimum time lapse by methods that shall maintain the required workability and will prevent segregation, loss of any ingredients or ingress of foreign matter or water. During hot or cold weather, concrete shall be transported in deep containers other suitable measures to reduce loss of water by evaporation and heat loss in cold weather may also be adopted. In all cases concrete shall be deposited as nearly as practicable directly in its final position to avoid rehandling. To avoid segregation, concrete shall not be rehandled or caused to flow. For locations where direct placement is not possible and in narrow forms and Contractor shall provide suitable drops and “Elephant Trunks”. Concrete shall not be dropped from a height of more than 1.0 m. Care shall be taken to avoid displacement of reinforcement or formwork. Concrete shall not be placed in flowing water. Under water, concrete shall be placed in position by tremies or by pipeline from the mixer and shall never be allowed to fall freely through the water. While placing concrete the Contractor shall proceed as specified below and also ensure the following: Continuously between construction joints and pre-determined abutments. Without disturbance to forms or reinforcement Without disturbance to pipes, ducts, fixings and the like to be cast in; ensure that such items are securely fixed. Ensure that concrete cannot enter open ends of pipes and conduits etc. Without dropping in a manner that could cause segregation or shock. Page | 193

In deep pours only when the concrete and formwork designed for this purpose and by using suitable chutes or pipes. Do not place if the workability is such that full compaction cannot be achieved Without disturbing the unsupported sides of excavations; prevent contamination of concrete with earth. Provide sheeting if necessary in supported excavations, withdraw the linings progressively as concrete is placed. If placed directly onto hardcore or any other porous material, dampen the surface to reduce loss of water from the concrete. Ensure that there is no damage or displacement to sheet membranes. Record the time and location of placing structural concrete. Concrete shall normally be compacted in its final position within thirty minutes of leaving the mixer. Concrete shall be compacted during placing with approved vibrating equipment without causing segregation until it forms a solid mass free from voids thoroughly worked around reinforcement and embedded fixtures and into all corners of the formwork. Immersion vibrators shall be inserted vertically at points not more than 450 mm apart and withdrawn slowly till air bubbles cease to come to the surface, leaving no voids. When placing concrete in layers advancing horizontally, care shall be taken to ensure adequate vibration, blending and melding of the concrete between successive layers. Vibrators shall not be allowed to come in contact with reinforcement, formwork and finished surfaces after start of initial set. Over-vibration shall be avoided; under vibration is likewise harmful. The vibrator should penetrate rapidly to the bottom of the layer and atleast 15 cm into the preceding layer if there is any. It should be held generally 5 to 15 sec. until the compaction is considered adequate and then withdrawn slowly at thereof about 8 cm/s. Concrete may be conveyed and placed by mechanically operated equipment after getting the complete procedure approved by the EIC. The slump shall be held to the minimum necessary for conveying concrete by this method. When concrete is to be pumped, the concrete mix shall be specially designed to suit pumping. Care shall be taken to avoid stoppages in work once pumping has started. Except when placing with slip forms, each placement of concrete in multiple lift work, shall be allowed to set for at least 24 hours after the final set of concrete before the start of subsequent placement. Placing shall stop when concrete reaches the top of the opening in walls or bottom surface of slab, in slab and beam construction, and it shall be resumed before concrete takes initial set but not until it has had time to settle as approved by the EIC. Concrete shall be protected against damage until final acceptance. 4.4.14 Mass Concrete Works Sequence of pouring for mass concrete works shall be as approved by the EIC. The Contractor shall exercise great care to prevent shrinkage cracks and shall monitor the temperature of the placed concrete if directed. 4.4.15 Curing Curing and protection shall start immediately after the compaction of the concrete to protect it from Page | 194

After the concrete has begun to harden i.e. 1 to 2 hr. after laying curing shall be started. All concrete, unless approved otherwise by the EIC, shall be cured by use of continuous sprays or ponded water or continuously saturated coverings of sacking, canvas, hessain or other absorbent material for the period of complete hydration with a minimum of 7 days. The quality of curing water shall be the same as that used for mixing. Where a curing membrane is approved to be used by the EIC, the same shall of a non-wax base and shall not impair the concrete finish in any manner. The curing compound to be used shall be approved by the EIC before use and shall be applied with spraying equipment capable of a smooth, even textured coat. When concrete is used as subgrade for flooring, the flooring may be commenced before the curing period of subgrade is over, but curing of subgrade shall be continued along with the top layer of flooring for a minimum period of 7 days. Curing may also be done by covering the surface with an impermeable material such as polyethylene, which shall be well sealed and fastened. 4.4.16 Construction Joints and Keys The position and arrangement of construction joints shall be as indicated by the contractor in his working drawings dually approved by the department. Concrete shall be placed without interruption until completion of work between construction joints. If stopping of concreting becomes unavoidable anywhere, a properly formed construction joint shall be made with the approval of the EIC. Dowels for concrete work, not likely to be taken up in the near future, shall be coated with cement slurry and encased in lean concrete as indicated on the drawings or as approved by the EIC. Before resuming concreting on a surface which has hardened all laitance and loose stone shall be thoroughly removed by wire brushing/hacking and surface washed with high pressure water jet and treated with thin layer of cement slurry for vertical joints and horizontal layers. When concreting is to be resumed on a surface which has not fully hardened, all laitance shall be removed by wire brushing, the surface wetted, free water removed and a coat of cement slurry applied. On this, a layer of concrete not exceeding 150 mm thickness shall be placed and well rammed against the old work. Thereafter work shall proceed in the normal way.

being gently tapped with a wooden mallet till it is properly bedded and in level with the adjoining tiles. The joints shall be in straight lines and shall normally be 1.5 mm wide. On completion of laying of the tiles in a room, all the joints shall be cleaned and washed fairly deep with a stiff broom/wire brush to a minimum depth of 5 mm. The day after the tiles have been laid, the joints shall be filled with cement grout of the same shade as the colour of the matrix of the tile. For this purpose white cement or grey cement with or without pigments shall be used. The freshly laid portions of the tiles shall be prevented from damage by providing suitable barriers. The flooring should be kept moist and left undisturbed for 7 days for the bedding /joints to set properly. After this it may be used for light traffic. Heavy traffic shall not be allowed on the floor for atleast 14 days after fixing of the tiles. About a week after laying the tiles, each and every tile shall be lightly tapped with a small wooden mallet to find out if it gives a hollow sound; if it does, such tiles along with any other cracked or broken tiles shall be removed and replaced with new tiles to proper line and level. The same procedure shall be followed again after grinding the tiles and all damaged tiles replaced, properly jointed and finished to match. For the purpose of ensuring that such replaced tiles match with those laid earlier, it is necessary that the Contractor shall procure sufficient quantity of extra tiles to meet this contingency. Wherever a full tile cannot be provided, tiles shall be cut to size and fixed. Floor tiles adjoining the wall shall go about 10 mm under the plaster, skirting or dado. The skirting and dado work shall be executed only after laying tiles on the floor. For dado and skirting work, the vertical wall surface shall be thoroughly cleaned and wetted. Thereafter it shall be evenly and uniformly covered with 10 mm thick backing of 1:4 cement sand mortar. For this work the tiles as obtained from the factory shall be of the size required and practically full polished. The back of each tile to be fixed shall be covered with a thin layer of neat cement paste and tile shall then be gently tapped against the wall with a wooden mallet. Fixing shall be done from the bottom of the wall upwards. The joints shall be in straight lines and shall normally be 1.5 mm wide. Any difference in the thickness of the tiles shall be evened out in the backing mortar or cement paste so that the tile faces are in conformity and truly plumb. Tiles for use at the corners shall be suitably cut with beveled edges to obtain a neat and true joint. After the work has set, hand polishing with carborundum stones shall be done so that the surface matches with the floor finish. Wall plastering of the strip left out above the level of skirting/dado shall be taken up after the tiles are fixed. Chequered terrazzo tiles for flooring and for stair treads shall be delivered to site after the first machine grinding. Machine grinding and polishing shall be commenced only after a lapse of 14 days of laying. The sequence and three numbers of machine grinding operations, usage of the type of carborundum stones, filling up of pin holes, watering etc. shall be carried out all as specified in IS : 1443. Tiles shall be laid to the levels specified. Where large areas are to be tiled the level of the central portion shall be kept 10 mm higher than that at the walls to overcome optical illusion of a depression in the central portion. Localised deviation of ± 3 mm in any 3 m length is acceptable in a nominally flat floor.

Clause 1:

Security Deposit

“The security deposit @ 10% of the gross amount of the running bill shall be deducted from each running bill and shall be refunded as per rules on completion of the contract as per terms and conditions. The earnest money deposited shall however be adjusted while deducting security deposit from the first running bill of the contractor. There will be no maximum limit of security deposit.

A contractor may, however, elect to furnish bank guarantee or any acceptable form of security for an amount equal to the full amount of security deposit @ 10% of the work order before or at the time of executing the agreement. In that case earnest money may be refunded only after furnishing of the bank guarantee as above.

These will be the matters between the Bank and the Contractor.

Clause 2:

Compensation for delay

The time allowed for carrying out the work (24 Months for execution part), as entered in the tender, shall be strictly observed by the Contractor and shall be reckoned from the 10th day after the date of written order to commence the work is given to the Contractor. If the Contractor does not commence the work within the period specified in the work order, he shall stand liable for the forfeiture of the amount of Earnest Money and Security Deposit. Besides, appropriate action may be taken by the Engineer-in-Charge/competent authority to debar him from taking part in future tenders for a specified period or black list him.

Note: In case delayed period over a particular span is split up and is jointly attributable to Government and contractor, the competent authority may reduce the compensation in proportion of delay attributable to Government over entire delayed period over that span after clubbing up the split delays attributable to Government and this reduced compensation would be applicable over the entire delayed period without paying any escalation. Following illustrations is given:-

First time span is 6 months, delay is of 30 days which is split over as under:-

5 days (attributable to Government) + 5 days (attributable to contractor) + 5 days (attributable to Government) + 5 days (attributable to contractor) + 5 days (attributable to Government) + 5 days (attributable to contractor) Total delay is thus clubbed to 15 days (attributable to Government) and 15 days (attributable to contractor).

The normal compensation of 30 days as per clause 2 of agreement is 2.5% which can be reduced as 2.5*15/30-1.25% over 30 days without any escalation by competent authority.

Note : The compensation, levied as above, shall be recoverable from the Running Account Bill to be paid immediately after the concerned time span. Total compensation for delays shall not exceed 10 percent of the total value of the work.

The contractor shall, further, be bound to carry out the work in accordance with the date and quantity entered in the progress statement attached to the tender.

In case the delay in execution of work is attributable to the contractor, the spanwise compensation, as laid down in this clause shall be mandatory. However, in case the slow progress in one time span is covered up within original stipulated period, then the amount of such compensation levied earlier shall be refunded. The Price escalation, if any, admissible under clause 45 of Conditions of Contract would be admissible only on such rates and cost of work, as would be admissible if work would have been carried out in that particular time span. The Engineer-in-Charge shall review the progress achieved in every time span, and grant stagewise extension in case of slow progress with compensation, if the delay is attributable to contractor, otherwise without compensation.

However, if for any special job, a time schedule has been submitted by the Contractor before execution of the agreement, and it is entered in agreement as well as same has been accepted by the Engineer-in-charge, the Contractor shall complete the work within the said time schedule. In the event of the Contractor failing to comply with this condition, he shall be liable to pay compensation as prescribed in forgoing paragraph of this clause provided that the entire amount of compensation to be levied under the provisions of this Clause shall not exceed 10% of the value of the contract. While granting extension in time attributable to the Government, reasons shall be recorded for each delay.
