joint is flush with both inside and with outside with the pipe wall .The jointing space is filled with cement

mortar in the proportion as specified in Data Sheet-1A, mixed sufficiently dry to remain in position when

forced with a trowel or rammer.

FLUSH JOINT (EXTERNAL)

This joint is suitable for pipes which are too small for jointing from inside. This joint is composed of

specially shaped pipe ends. Each end shall be butted against each other and adjusted in correct position.

The jointing space shall then be filled with cement mortar as specified in Data Sheet-1A, sufficiently dry

and finished off flush. Great care shall be taken to ensure that the projecting ends are not damaged as no

repairs can be readily effected from inside the pipe.

SPIGOT AND SOCKET (SEMI-FLEXIBLE)

This joint is composed of specially shaped spigot and socket ends on the RCC pipes. A rubber ring as

specified in Data Sheet-1A, shall be lubricated and then placed on the spigot which is forced into the

socket of the pipe previously laid. This compresses the rubber ring as it rolls into the annular space

formed between the two surface of the spigot and socket, stiff mixture of cement and mortar as specified

in Data Sheet-1A, shall then be filled into the remaining annular with a caulking tool.

COLLAR JOINT (SEMI-FLEXIBLE)

This joint is made up of a loose collar, which covers two specially shaped pipe ends. Each end shall be

fitted with a rubber ring as specified in Data Sheet-1A, which when compressed between the spigot and

collar, seals the joint. Stiff mixture of cement mortar as specified in Data Sheet-1A, shall then be filled into

the remaining annular space and rammed with a caulking tool.

SPIGOT AND SOCKET JOINT (FLEXIBLE)

The RCC pipe with the rubber ring accurately positioned on the spigot shall be pushed well home into the

socket of the previously laid pipe by means of uniformity applied pressure with the aid of a jack of similar

appliance. The RCC pipes shall be of spigot and socket type and rubber rings as specified in Data Sheet -

1A, shall be used, and the manufactures instructions shall be used, and the manufacturers instructions

shall be deemed to form a part of these specifications. The rubber rings shall be lubricated before making

CLEANING OF PIPES

As soon as a stretch of RCC pipes has been laid complete from M.H. of for a stretch as directed by

owner/Engineer contractor shall run through the pipes both backwards and forwards a double disc or

solid or closed cylinder 75mm less in diameter than the internal diameter of pipes. The open end of an

incomplete stretch of pipeline shall be securely closed as may be directed by owner/Engineer to prevent

entry of mud or silt etc.

If as a result of the removal of any obstructions Owner/Engineer considers that damages may have been

caused to the pipe lines, he shall be entitled to order the stretch to be tested immediately. Should such

test prove unsatisfactory, contractor shall amend the work and carry out such further tests as are

required by owner/Engineer.

It shall also be ascertained by contractor that each stretch from M.H. to M.H. or the stretch as directed by

Engineer is absolutely clear and without any obstruction by means of visual examination of the interior of

the pipe line suitable enlightened by projected sunlight or otherwise.

TESTING AT WORK SITE

After laying and jointing of RCC pipes is completed the pipe shall be tested at work site as per the

following specifications and as directed by owner/Engineer. All equipment for testing at work site shall be

supplied and erected by contractor. Water for testing of pipes shall be arranged by him. Damage during

testing shall be rectified by him to the full satisfaction of owner/Engineer. Water used for test shall be

removed from pipes and not released to the excavated trenches.

After the joints have thoroughly set and have been checked by Owner/Engineer and before back filling the

trenches, the entire section

of the sewer or storm water drain shall be proved by contractor to be water tight by filling in pipes with

water to the level of 1.50 m. above the top of the highest pipe in the stretch and heading the water up for

the period of one-hour. The apparatus used for the purpose of testing shall be approved by

owner/Engineer. Contractor if required by Owner/Engineer shall dewater the excavated pit and keep it

dry during the period of testing. Adding water from a measuring vessel at regular 10 minutes intervals and

noting the quantity required to maintain the original water level should measure the loss of water over a

period of 30 minutes. For the approval of this test the average quantity added should not exceed

1litre/hour/100 linear metres/10 mm of nominal internal diameter. Any leakage including excessive

sweating which causes a drop in the test water level will be visible and the defective part of the work

should be removed and made good.

In case of pressure pipeline the completed stretch to pipeline shall be tested for site test pressure as

specified in Data Sheet-1A. The site test pressure should not be less than the maximum operating

pressure plus the calculated surge pressure, but in no case should it exceed the hydrostatic test pressure

as specified in IS :

All RCC pipes shall be measured according to the work actually done and no allowance will be made for

any waster in cutting to the exact length required. The measurement for pipes shall be in running meters

nearest to a cm. of length along the center line of pipe as actually laid at work sites.

The rate for providing, laying and jointing of RCC pipes shall be deemed to include the cost of

collars/rubber rings, jointing material, testing and extra excavation required for ordinary bedding of pipes

and also for collars and pipe sockets, if any.

If any damage is caused to the pipeline during the execution of work or while cleaning/ testing the

pipeline as specified, Contractor shall be held responsible for the same and shall replace the damaged

pipeline and retest the same at his own cost to the full satisfaction of Engineer.

Water for testing of pipeline shall be arranged by contractor at his own cost.

PART 2 LAYING OF PIPES AND FITTINGS/SPECIALS

This specification covers the requirements for laying of pipes and

fittings/specials below ground.

APPLICABLE CODES

The laying of pipes and fittings/ specials shall comply with all currently applicable statutes, regulations,

standards and codes. In particular, the following standards, unless otherwise specified herein, shall be

referred to. In all cases, the latest revision of the standards/ codes shall be referred to. If requirements of

this specification conflict with the requirements of the standards/codes, this specification shall govern.

CODES OF PRACTICE

(a) IS : 783 - Code of practice for laying of concrete pipes.

(b) IS : 3114 - Code of practice for laying of cast iron pipes.

(c) IS : 3764 - Safety codes for excavation work

(e) IS : 5822 - Code of practice for laying of welded steel pipes for water supply

(f) IS : 6530 - Code of practice for laying of asbestos cement pressure pipes

CARTING & HANDLING

Pipes and fittings/ specials shall be transported from the factory to the work sites at places along the

alignment of pipeline as directed by Owner/ Engineer. Contractor shall be responsible for the safety of

pipes and fittings/ specials in transit, loading/ unloading. Every care shall be exercised in handling pipes

and fittings/ specials to avoid damage. While unloading, the pipes and fittings/ specials shall not be

thrown down from the truck on to hard surfaces. They should be unloaded on timber skids with steadying

ropes or by any other approved means. Padding shall be provided between coated pipes, fittings/ specials

and timber skids to avoid damage to the coating. Suitable gaps between pipes should be left at intervals in

order to permit access from one side to the other. In case of spigot socket pipes, care should be taken

regarding orientation of pipes while unloading. As far as possible pipes shall be unloaded on one side of

the trench only. The pipes shall be checked for any visible damage (such as broken edges, cracking or

spilling of pipe etc.) while unloading and shall be sorted out for reclamation. Any pipe, which shows

sufficient damage to

prelude it from being used, shall be discarded. Dragging of pipes and fittings/ specials along concrete and

similar pavement with hard surfaces shall be prohibited.

Each stack of pipes shall contain only pipes of same class and size, with consignment or batch number

marked on it with particulars of suppliers/manufacturer wherever possible. Storage shall be done on firm

level and clean ground and wedges shall be provided at the bottom layer to keep the stack stable. The

stack shall be in pyramid shape or the pipes laid length wise and crosswise in alternate layers. The

pyramid stack shall be made for smaller diameter pipes for conserving space in storing them. The height

of the stack shall not exceed 1.5 m.

Fittings/specials shall be stacked under cover and separated from pipes. Rubber rings shall be stored in a

clean, cool store away from windows, boiler, electrical equipment and petrol, oils or other chemicals.

Particularity in the field where the rubber rings are being used it is desirable that they are not left out on

the ground in the sun or overnight under heavy frost or snow conditions.

Before excavating the trench the alignment of pipeline shall be approved by Owner/Engineer. The

excavation of trenches and pits for M.H.s /chambers shall be carried out in accordance with the

specification mentioned in Part: 3 and shall be done such that it does not get far ahead of the laying

operation as approved by Owner/Engineer.

To protect persons from injury and to avoid damage to property, adequate barricades, construction signs,

red lanterns and guards as required shall be placed and maintained during the progress of the

construction work and until it is safe for the traffic to use the roadways. The relevant Indian standards and

the rules and regulations of local authorities in regards to safety provisions shall be observed.

Suitable fencing shall be provided along the sides of trenches and pits. The posts of fencing shall be of

timber securely fixed in the ground not more than 3m apart and they shall not be less than 75mm in

diameter or less than 1.2 m above surface of the ground. There shall be two rails, one near the top of the

posts and the other about 450mm above the ground and each shall be from 50mm to 70mm in diameter

and sufficiently long to run from post to post to which they shall be bound with strong rope. The method

of projecting rails beyond the posts and tying them together where they meet will not be allowed on any

account. All along the edges of the excavated

trenches a bank of earth about 1.2 m high shall be formed where required by Owner/ Engineer for further

The road metal and also the rubble packing shall first be stripped off for the whole width of the trench/pit

and stacked separately as directed by Owner/ Engineer so as to reuse the same.

During excavation, large stones and rubble shall be separated and removed from the excavated soil and

stacked separately. The material from excavation shall be deposited on either side of the trench leaving

adequate clear distance from the edges of the trench and pit, or as may be necessary to prevent the sides

of the trench/pit to slip or fall, or at such a distance and in such a manner as to avoid covering fire

hydrants, sluice valves, M.H.s covers etc. and so as to avoid abutting the wall or structure or causing

inconvenience to the public and other service organizations or otherwise as Owner/ Engineer may direct.

Contractor shall take into account additional excavation if any as Owner /Engineer may require in order to

locate the position of water pipes, drains, sewers etc. or any other works which may be met with, in or

about the excavation of trenches/pits while quoting the rates for excavation. Such service lines if met with

during excavation shall be properly maintained by contractor, by means of shoring, strutting, planking

over, padding or otherwise as Owner/ Engineer may direct, and shall be protected by the Contractor from

damage during the progress of the work. All precautions shall be taken during excavation and laying

operations to guard against possible damage to any existing structure/ pipe line of water, gas sewage etc.

If the work for which the excavation has been made is not completed by the expected date of the setting

of monsoon as stipulated in Data Sheet-2A or the setting in of rain whichever is earlier, or before the day

fixed by Owner/ Engineer for filling in any excavation on account of any festival or special occasion, the

Contractor shall backfill the trench / pit and consolidate the filling as directed by Engineer/Owner.

Utmost care shall be taken to see that the width of the trench at the top of pipe is not more than that

specified below.

FOR RCC PIPES LESS THEN OR EQUALS TO 900 MM1.5 D + .3 M

WHERE D IS INTERNALDIA OF PIPES IN METER

FOR RCC PIPES GREATER THEN 900 MM OD + .6 M

WHERE OD IS THE OUTER DIA OF PIPE IN METER

In case additional width is required it shall be provided only in the top portion from the ground level up to

300mm above the top of pipe. If any extra width is provided in the area below this portion, Contractor

shall have to provide remedial measures in the form of lime concrete or rubble masonry or otherwise at

the discretion and to the satisfaction of Owner/ Engineer. If rock is met with, it shall be removed to 15cm

below the bottom of pipes and fittings/ specials and the space resulting shall be refilled with granular

materials and resulting shall be refilled with granular materials and properly consolidated. Bottom of

trenches/pits shall be saturated with water well rammed wherever Owner/ Engineer may consider it

necessary to do so.

Wherever a socket or collar of pipe or fitting special occurs a grip is to be cut in the bottom of the trench

or concrete bed to a depth of at least 75mm below the bed of the pipes so that the pipe may have a fair

bearing on its shaft and does not rest upon its socket. Such grip shall be of sufficient size in every respect

to admit the hand all around the socket in order to make the joint and the grip shall be maintained clear

until the joint has been approved by Owner/ Engineer.

When welding is to be carried out with the pipes and specials in the trench, additional excavation of not

more than 60cm in depth and 90cm in length shall be made at joints in order to facilitate welding.

The excess excavated material shall be carried away from site of works to a place up to a distance as

directed by Owner/ Engineer. This shall be done immediately so as not to cause any inconvenience to the

public or traffic. If the instructions from Engineer are not implemented within seven days from the date of

instructions to cart the materials and to clear the site, the same shall be carried out by Owner/ Engineer

at the risk and the cost of the contractor and any claim or dispute shall not be entertained in this respect.

During the excavation, if subsoil water is met, Contractor shall have to provide necessary equipment and

labors for dewatering the trenches/pits, by bailing out water or water mixed with soil or chemicals also ; if

pumping out subsoil water is found to be necessary, Contractor shall provide sufficient number of pumps

as suggested by the Engineer for the same. In both the above cases the excavation shall be done to the

required level and the pipes shall be laid to proper alignment and gradient. Contractor shall also make

necessary arrangement for the disposal of drained water to nearby storm water drain or a pit if allowed

by Owner/ Engineer. In no case the water shall be allowed to spread over the adjoining area. Before

discharging this water into public sewer/ drain, Contractor shall take necessary permission from the local

SPECIAL FOUNDATION IN POOR SOIL

Where the bottom of the trench at sub-grade is found to consist of material which is unstable to such a

degree that in the opinion of Owner/ Engineer, it cannot be removed and replaced the contractor shall

provide special foundation with an approved material thoroughly compacted in place to support the pipe

properly, a suitable foundation for the pipes, consisting of piling, timbers or other materials, in

accordance with relevant drawings and as instructed by Owner/Engineer shall be constructed.

Contractor shall suitably design polling boards, waling and struts to meet different soil conditions that

might be encountered in excavating trenches /pits. The horizontal and vertical spacing of struts shall be

such that not only the sides of trenches shall be prevented from collapse but also easy lowering of pipe in

trenches shall be ensured without creating undue obstructions for the excavation of the work. Any

inconvenience and/or delay that might be caused in lowering pipes in trenches as a result of adopting

improper spacing of struts by Contractor shall be his sole responsibility. Contractor shall at any time

remove no part of shoring without obtaining permission from Owner/ Engineer. While taking out shoring

planks the hollows of any form must simultaneously be filled in with slot earth well rammed with

rammers and with water.

Owner/ Engineer may order portions of shoring to be left in then trenches /pits at such places, where it is

found absolutely necessary to do so to avoid any damage which may be caused to buildings, cables, gas-

mains, water mains, sewers etc. pulling out the shoring from the excavations. Contractor shall not claim,

on may reason whatsoever, for the shoring, which may have been left in by him at own discretion.

STEEL PLATE SHORING

Where the subsoil conditions are expected to be of a soft and unstable character in trench/pit excavation,

the normal method of timbering may prove insufficient to avoid subsidence of the adjoining road surfaces

and other services. In such circumstances Contractor will be required to use steel trench sheeting or sheet

piling adequately supported by timber struts, waling etc., as per the instructions, manner and method

directed by Owner/ Engineer. Contractor shall supply, pitch, drive and subsequently remove trench

sheeting or piling in accordance with other items of the specification.

BONING STAVES AND SIGHT RAILS

In laying the pipes and fittings/ specials the center for each M.H./ chamber or pipeline shall be marked by

a peg. Contractor shall dig holes for and set up two post (about 100mm x100mm x1900 mm) at each

M.H./ chamber or junction of pipelines at nearly equal distance from the peg and at sufficient distances

there from to be well clear of all intended excavation, so arranged that a sight rail when fixed at a certain

level against the post shall cross the center line of the M.H./ chamber or pipes lines. The sight rail shall not

in any case be more than 30m apart, intermediate rails shall be put up if directed by Owner/Engineer.

Boning staves of 75mm x 50mm size shall be prepared by Contractor in various lengths, each length being

of a certain whole number of meters and a fixed tee-head and fixed intermediate cross pieces, each about

300 mm long. The top-edge of the cross piece must be fixed below the top-edge of this tee-head at a

distance equal to the outside diameter of the pipe or the thickness of the concrete bed to be laid as the

case may be. The top of cross pieces shall indicate different levels such as excavation for pipe line, top of

concrete bed, top of pipe etc. as the case may be.

The sight rail of size 250 mm x 40 mm shall be screwed with the top edge resting against the level marks.

The centerline of the pipe shall be marked on the rail and this mark shall denote also the meeting point of

the center lines of any converging pipes. A line drawn from the top edge of one rail to the top edge of the

next rail shall be vertically parallel with the bed of the pipe, and the depth of the bed of pipe at any

intermediate point may be determined by letting down the selected boning staff until the tee head comes

on the line of sight from rail to rail.

The post and rails shall be perfectly square and planed smooth on all sides and edges. The rails shall be

painted white on both sides, and tee-heads and cross-piece of the boning staves shall be painted black.

For the pipes converging to M.H./ chamber at various levels, there shall be a rail fixed for every different

level. When a rail comes within 0.60 M of the surface of the ground, a higher sight-rail shall be fixed for

use with the rail over the next point.

The posts and rails shall in no case be removed until the trench is excavated, the pipes are laid and

Owner/Engineer gives permission to proceed with the back filling.

The type of bedding for pipes shall be granular bedding as specified and directed by Engineer-in-charge.

Laying of pipes and fittings/specials All precautions shall be taken during excavation and laying operations

to guard against possible damage to any existing structure/ pipeline of water, gas, sewage etc. After

excavation of trenches, pipes shall not be lowered unless the dimensions of trenches and bedding work

for pipes at the bottom of the trenches are approved and measured by Owner/Engineer. Pipes and

fittings/specials shall be carefully lowered in the trenches. Special arrangements such as cranes, tripods

with chain pulley block for lowering the pipes and fittings/ specials shall be made by Contractor. In no

case pipes and fittings/ specials shall be dropped. Slings of canvas or equally non-abrasive material of

suitable width or special attachment to fit the ends of pipes and fittings/ specials shall be used to lift and

lower the coated pipes and fittings/specials. The pipes and fittings/specials shall be inspected for defects

and be rung with a light hammer preferably while suspended to detect cracks. If doubt persists, further

confirmation shall be done by pouring a little kerosene/dye on the inside of the pipe at the suspected

spot. No sign of kerosene/dye should appear on the outside surface. Pipes and fittings/specials damaged

during lowering or aligning shall be rejected by Owner/ Engineer.

All the pipes are to be laid perfectly true both in alignment and to gradient specified. In case of spigot and

socket pipe the socket end of the pipe shall face upstream, except when the pipelines runs uphill in which

case the socket ends should face the upgrade. The lying of pipes shall always proceed upgrade of a slope.

After placing a pipe in the trench, the spigot end shall be entered in the socket and the pipe forced home

and aligned to required gradients. The pipes shall be secured in place with approved backfill material

tamped under it except at the socket. Pipes and fittings/ specials which do not allow a sufficient and

uniform space for joints shall be removed and replaced with pipes and fittings/ specials of proper

dimensions to ensure such uniform space. Precautions shall be taken to prevent dirt from entering the

jointing space. At times when pipe laying is not in progress, the open ends of pipe shall be closed by a

watertight plug or other means approved by Owner/ Engineer. During the period that the

plug is on, the Contractor shall take proper precautions against floating of the pipe owing to entry of

water into the trench. Wherever it is necessary to deflect pipe form a straight line, either in the vertical of

horizontal plane, to avoid obstruction or where long radius curve are permitted the deflection allowed at

joints shall not exceed 2 1/2o. In case of pipes, with joint to be made with loose collars, the collars shall be

slipped on before the next pipe is laid. The pipes shall be laid such that the marking on pipes appears at

the top of the pipes.

The cutting of pipe for inserting valves, fittings or specials shall be done in a neat and workman like

manner without damage to the pipe so as to leave a smooth end at right angles to the axis of the pipe. For

this purpose, pipe-cutting machine shall be used.

Thrust blocks shall be provided, to counteract hydraulic thrust, at places wherever directed by

owner/engineer and as per relevant drawing

Contractor shall suitably design polling boards, waling and struts to meet different soil conditions that

might be encountered in excavating trenches /pits. The horizontal and vertical spacing of struts shall be

such that not only the sides of trenches shall be prevented from collapse but also easy lowering of pipe in

trenches shall be ensured without creating undue obstructions for the excavation of the work. Any
