dimensions shown on the plan or as directed by the Engineer-in- Charge with due allowance for

shrinkage for compaction.

Material : All the useful and acceptable materials of approved quality obtained from the

contractor’s borrow areas shall be used for the embankment work. The borrow areas shall be got

approved prior to bringing material to site of work from the Engineer-in-Charge. All the useful and

approved material obtained from contractor’s borrow areas as directed shall be used for the

embankment work. Approved quality murum or a mixture of sand, murum, gravel, small boulders

or rubble as approved shall be used. Black cotton soil, shadu or shrinkable soils shall not be used.

Murum having laboratory dry density of less than 1.65 gm/cc shall be rejected. For embankments

upto 3 m in height, murum with laboratory dry density of less than 1.65 gm/ cc shall not be used.

Only the tested materials approved by the Engineer-in-Charge shall be used for the embankment.

Rejected materials shall not be brought to the work site. The perishable materials such as stumps,

pieces of wood, roots, rubbish, etc. shall be removed from the embankment material. The material

required for embankment shall be obtained by the contractor from the approved quarries by the

Engineer-in-Charge: - All lifts and specified leads involved in conveying the material to site shall be

included in the rate. The payment of taxes, duties, octroi and royalty as per rules and regulations

levied by the Govt. shall have to be paid by the contractor. The Contractor shall be responsible

regarding any claims if any, that may be made by private owners. The payment of royalty charges

is to be born by the contractor and no reimbursement from MIDC is admissible.

Setting Out : Alignment of the road shall be set out as shown in the drawing or as directed to true

lines, curves, and grades. Profiles shall be set out with stout poles to mark the center and edges of

the formation width with the top levels of formation clearly marked by paint or cut and the slopes

with string and pegs at every 30 meters on straight portions and 10m or less on curves or as

directed by the Engineer-in-Charge. The toe line shall be marked with pick marks. Longitudinal

and cross-section levels shall be taken recorded and signed by the contractor or his authorized

representative and also by the Engineer-in-charge. All the materials and labour required for this

item shall be supplied by the contractor and profiles, B.M.s etc. shall be put up by the contractor.

The cost of these operations is included in the rate of this item. Profiles, pegs, benchmarks and

other marks shall be maintained without any disturbance till the completion of the work, and as

directed by the Engineer-in-charge.

Equipment: Pickaxes, crowbars, phawras, and Ghamelas maybe used for carrying out work

manually. The scrapers, dozers, graders, shovels, dumpers, trucks, trolleys, etc. may be used for

executing work using mechanical equipments. Three wheels, 8 tones Power Roller giving a

pressure required to obtain the specified density may be used for compaction. Bullock carts with

water tanks or mechanically driven water tankers may be used for watering. The contractor shall

submit the list of equipments available with him and intended to be used on the work and shall got

approved for their use from the Engineer-incharge.

Construction Methods :

Diversions : If diversions, barricading and signals for day and night are necessary, they shall be

provided without any extra cost.

Preparing the Ground for Laying Bank : Before any material is laid for the embankment the

ground shall be cleared of all rubbish, removing bushes, etc., and the holes, if any, filled up. When

the embankment is to be laid on hillsides or slopes, the existing slopes shall be ploughed deeply. If

the cross slopes are steeper than 1 in 3, steps with reverse slope shall be cut into the slopes to

give proper hold and seating to the bank as directed by the Engineer-in-Charge. On surfaces flatter

than 1 in 15, no special surface treatment such as cutting steps shall be necessary. The top 15 cm

of soil shall be scarified and watered as directed and compacted to the same density as specified

for the embankment before any material is laid for the Bank-work. When the embankment is to be

placed over an existing road, which is within 15 cm of the finished formation, the road or other hard

surface shall be scarified to a minimum depth of 15 cm for which payment shall be made

separately under relevant item of road excavation. The rate for embankment includes all the

operations for preparing the bed for laying the embankment material.

Laying the Bank : Embankment material shall be placed in successive horizontal layers of 20 cm

to 30 cm thickness extending to the full width of the embankment including the slopes at the level

of the particular location and 30 cm more on both sides to allow compaction of the full specified

section. The extra loose stuff at the edges shall be trimmed after completion of the embankment

work without extra cost leaving the correct section fully compacted. Keeping width of the bank

initially less and widening it later by dumping loose earth on the slopes shall not be permitted as

the additional width and slopes may remain loose and uncompacted and may not have been

compacted as earlier carried out work. Similar procedure to extend the embankment by dumping

the material longitudinally shall also not be allowed. When boulders, broken stones, and similar

hard materials are mixed up with the embankment materials, care shall be taken to see that they

are distributed uniformly in to the embankment and that no hollows are left near them. No stone or

hard material shall project above the top of any layer. Each layer of embankment shall be watered,

leveled and compacted as specified, before the succeeding layer is placed. The surface of the

embankment shall, at all times during construction, be maintained at such a cross fall to shed

water and prevent ponding. If bridges and culverts on the road are not completed in advance of

embankment work, a length of 15 m bank shall be left on each side of the structure and these

lengths shall dealt with later for placing the embankment work. The contractor shall construct

temporary diversion road till the work of culverts and bridges are completed and all type of traffic is

allowed to be passed on these bridges and culverts. The camber stipulated shall be provided in the

embankment only and shall not be adjusted in metalling.

Protection : Proper care shall be taken to ensure that the method of operation and compaction of

the bank-work does not cause damage or undue strain to any structural element. Embankment

over and around bridges or culverts shall be of approved materials and carefully placed and

compacted. The contractor shall take all precautions necessary for the protection of the bank-work

by diversions of streams, local surface drainage, rain water, etc. likely to damage the bank. Any

damage to the embankment-work due to no protection or inadequate protection shall be made

good by the contractor at his own cost. Conveyance of materials shall not cause obstruction or

nuisance to the nearby property owners and traffic.

Finishing : The embankment shall be finished and dressed smooth and even in conformity with

the alignment, levels, cross-sections and dimensions shown on the drawing with due allowances

for shrinkage. On curves, sections shall be provided with super elevation and increased widths as

shown on the plans or directed by the Engineer-in- Charge. All damages caused by rain, flood or

any other reasons shall be made good in the finishing operations without any extra cost by the

contractor. The road land width shall be cleared.

holes left in masonry works for scaffolding purposes shall be filled and

made good before plastering.

Note : In case of special stonework, scaffolding shall be got approved

from Engineer-in-charge in advance.

Application of Pointing and Finishing :

1. The mortar shall be pressed into the raked out joints, with a

pointing trowel, either flush, sunk or raised, according to the

type of pointing required. The mortar shall not spread over the

corner, edges of surface of the masonry. The pointing shall then

be finished with the proper tool, in the manner described below.

2. Flush Pointing : The mortar shall be pressed into the joints and

shall be finished off flush and level with edges of the stones,

tiles or stones so as to give a smooth appearance. The edges

shall be neatly trimmed with a trowel and straight edge.

3. Ruled Pointing : The joints shall be initially formed as for

flush pointing and then while the mortar is still green, a groove

of shape and size as shown in drawings or as instructed, shall

be formed by running a forming tool, straight along the centre

line of the joints. This operation shall be continued till a smooth

and hard surface is obtained. The vertical joints shall also be

finished in a similar way. The vertical lines shall make true

right angles at their junctions with the horizontal lines and shall

not project beyond the same.

4. Raised and Cut Pointing : Raised and cut pointing shall

project from the wall facing with its edges cut parallel so as to

have a uniformly raised band about 6 mm raised and width 10

mm more as directed.

5. The superfluous mortar shall then be cut off from the edges of

the lines and the surface of the masonry shall also be cleaned

off all mortar. The finish shall be such at the pointing is the

exact size and shape required and the edges are straight, neat

and clean.

6. The pointing lines shall be truly horizontal and vertical except

where the joints are slanting as in rubble random masonry.

Lines of joints from different directions should meet neatly at

the junctions instead of crossing beyond.

by chain pulley block for pipes 1000 mm and above is recommended. All pipe sections and

connections shall be inspected carefully before being laid. Broken or defective pipes or

connections shall not be used and paid. Pipes shall be lowered into the trenches carefully.

Mechanical appliances shall be used. Pipes shall be laid true to line and grade as specified. Laying

of pipe shall proceed upgrade of a slope. If the pipe have spigot and socket joints, the socket ends

shall face ascending gradient. In the case of pipes with joints to be made with loose collars, the

collars shall be slipped on before the next pipe is laid. Adequate and proper joints shall be

provided as directed. In case where foundation condition are unusual such as in the proximity of

trees, under existing or proposed tracks manholes etc. the pipe shall be encased all around in 15

cm thick cement concrete M15 grade or compacted sand or gravel. In cases where the natural

foundation is inadequate the pipes shall be laid either on concrete cradle supported on proper

foundations or on any other suitably designed structure. If concrete cradle bedding is used, the

depth of concrete below the bottom of the pipe shall be at least 1/4th of the internal diameter of the

pipe subject to the min. of 10 cm and a maximum of 30 cm. The concrete shall extend beyond both

the sides of the pipe at least to a distance of 1/4th of the outside diameter subject to minimum 10

cm and maximum 30 cm. The pipe shall be laid on this concrete bedding before setting of the

concrete . Pipes laid in trenches in earth shall be bedded evenly and firmly and as far up the

haunches of the pipe as to safely transmit the load expected from the backfill through the pipe to

the bed. This shall be done either

by excavating the bottom of the trench to fit the curve of the pipe or by compacting the earth under

around the curve of the pipe to form an even bed. Necessary provision shall be made for joints

wherever required. When the pipe is laid in a trench in rock, hard clay, shale or other hard material

the 15 cms depth below the pipe shall be excavated and refilled with an equalizing bed cushion of

15 cms thickness of granular approved granular soft murum, sand or compacted earth. In no case

the pipe shall be laid directly on such hard material. It should be ensured that the rock protrudes

shall be knocked off. When the pipes are laid completely above the ground the foundations shall

be made even and sufficiently compacted to support the pipeline without any material settlement.

Alternatively the pipeline shall be supported on rigid foundations at intervals as approved by the

Engineer-in-Charge. Suitable arrangements shall be made to retain the pipeline in the proper

alignment, such as by shaping the top of the supports to fit the lower part of the pipe. The distance

between the supports shall in no case exceed the length of the pipe. The pipe shall be supported

as far as possible close to the joints. In no case the joints shall come in the centre of the span.

Suitably designed anchor blocks at change of direction and grades for pressure lines shall be

provided where required. The cost of bedding below pipes, concrete and/or murum supports

constructed, anchor blocks etc. is not included in the scope of item and shall be paid separately

under relevant items included in the tender Jointing : Joints shall generally be of rigid type. Where

specified flexible type joints may also be provided, an approval of Engineer-in- Charge. Rigid

Spigot & Socket Joint : The spigot of each pipe shall be slipped home well into the socket of the

pipe previously laid and adjusted in the correct position. The opening of the joint shall be filled with

stiff mixture of cement mortar in the proportion of 1:1 (1 cement : 1 fine sand) which shall be

rammed with caulking tool and finished at 45° tapper. After a day’s work any extraneous material

shall be removed from the inside of the pipe and the newly made joint shall be cured at least for 7

days. Rigid Collar Joint : The two adjoining pipes shall be butted against each other and adjusted

in correct position. The collar shall then be slipped over the joint, covering equally both the pipes.

The annular space shall be filled with stiff mixture of cement mortar 1:1 (1 cement : 1 fine sand)

which shall be rammed with caulking tool and finished at 45° tapper. After a day’s work any

extraneous materials shall be

removed from the inside of the pipe and the newly made joint shall be cured at least for 7 days.

Flexible Spigot & Socket Joint : The joint is composed of specially shaped spigot and socket ends

on the concrete pipes. A rubber ring shall be placed on the spigot, which shall be 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 surfaces of the spigot and the socket. Flexible Collar Joint : This shall be

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

with a rubber ring which when compressed between the spigot and the collar, seal the joint.

Internal Flush Joint : This joint shall generally be used for culvert pipe of 60 cm diameter and

above. The ends of the pipe are specially shaped to form a self-centering joint with an internal

jointing space 1.3 cm wide. The finished joint shall be flush with both inside and outside with the

pipe wall. The jointing space shall be filled with cement mortar 1:1 (1 cement : 1 fine sand) mixed

sufficiently dry to remain in position when forced with a trowel or rammer and finished at 45°

tapper. After day’s work any extraneous materials shall be removed from the inside of the pipe and

the newly made joint shall be cured at least for 7 days. External Flush Joint : 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 1:1 (1 cement : 1 fine sand) sufficiently dry

and finished off flush at 45° tapper. Great care shall be taken to ensure that the projecting ends

are not damaged as no repairs can be readily affected from inside the pipe. In all pressure

pipelines the recess at the end of the pipe line shall be filled with jute braiding dipped in hot

bitumen or other suitable approved compound. Pipes shall be so jointed that the bitumen ring of

one pipe shall set into the recess of the next pipe. The ring shall be thoroughly compressed by

jacking or by any other suitable method.

The number of pipes that shall be jacked together at a time shall depend on the diameter of the

pipes and the bearing capacity of the soil, for small pipes upto 25 cm diameter, six pipes can be

jacked together at a time. The quantity of jute and bitumen in the ring shall be just sufficient to

fill the recess in the pipe when presses hard by jacking or by any other suitable method. Before

and during jacking care shall be taken to see that there is no offset at the joint.

Testing : Smoke test shall be carried out from chamber to chamber at contractor’s cost.

Refilling of Trenches : In case where pipes are not bedded on concrete special care shall be

taken in refilling trenches, to prevent the displacement and subsequent settlement at the surface

resulting in uneven surface and dangers to foundations etc. The back filling materials shall be

packed by hand under and around the pipe and rammed with a shovel and light tamper. This

method of filling will be continued upto the top of pipe. The refilling shall rise evenly on both sides

of the pipe continued upto 60 cm above the top of pipe so as not to disturb the pipe. No tamping

shall be done within 15 cm of the top of pipe. The tamping shall become progressively heavier as

the depth of the backfill increases (item of excavation shall be paid under relevant item of

excavation of tender).

Cement Concrete Pipes (with and without Reinforcement)

The pipes shall be with or without reinforcement as required and shall be of the specified class.

These shall conform to IS : 458-1988. The reinforced cement concrete pipes shall be

manufactured by centrifugal (or spun) process and only reinforced is proposed for use NP2 by

providing temperature steel reinforcement. All pipes shall be true to shape, straight, perfectly

sound and free from cracks and flaws. The external and internal surface of the pipes shall be

smooth and hard. The

pipes shall be free from defects resulting from imperfect grading of the aggregate mixing or

molding. Concrete used for the manufacture of un-reinforced and reinforced concrete pipes and

collars shall not be leaner than M-15 grade C.C. The maximum size of aggregate should not

exceed one third of the thickness of the pipe or 20 mm whichever is less. The reinforcement in the

reinforced concrete pipes shall extend throughout the length of the pipe. The circumferential and

longitudinal reinforcements shall be adequate to withstand the specified hydrostatic pressure and

further bending stresses due to the weight of water when running full across a span equal to the

length of pipe plus three times its own weight.

Laying & Jointing Cement Concrete Pipes And Specials :

Laying : Loading, transporting and unloading of concrete pipes shall be done with care. Handling

shall be such as to avoid impact. Gradual unloading by inclined plane upto 900 mm dia pipes and

by chain pulley block for pipes 1000 mm and above is recommended. All pipe sections and

connections shall be inspected carefully before being laid. Broken or defective pipes or

connections shall not be used and paid. Pipes shall be lowered into the trenches carefully.

Mechanical appliances shall be used. Pipes shall be laid true to line and grade as specified. Laying

of pipe shall proceed upgrade of a slope. If the pipe have spigot and socket joints, the socket ends

shall face ascending gradient. In the case of pipes with joints to be made with loose collars, the

collars shall be slipped on before the next pipe is laid. Adequate and proper joints shall be

provided as directed. In case where foundation condition are unusual such as in the proximity of

trees, under existing or proposed tracks manholes etc. the pipe shall be encased all around in 15

cm thick cement concrete M15 grade or compacted sand or gravel. In cases where the natural

foundation is inadequate the pipes shall be laid either on concrete cradle supported on proper

foundations or on any other suitably designed structure. If concrete cradle bedding is used, the

depth of concrete below the bottom of the pipe shall be at least 1/4th of the internal diameter of the

pipe subject to the min. of 10 cm and a maximum of 30 cm. The concrete shall extend beyond both

the sides of the pipe at least to a distance of 1/4th of the outside diameter subject to minimum 10

cm and maximum 30 cm. The pipe shall be laid on this concrete bedding before setting of the

concrete . Pipes laid in trenches in earth shall be bedded evenly and firmly and as far up the

haunches of the pipe as to safely transmit the load expected from the backfill through the pipe to

the bed. This shall be done either

by excavating the bottom of the trench to fit the curve of the pipe or by compacting the earth under

around the curve of the pipe to form an even bed. Necessary provision shall be made for joints

wherever required. When the pipe is laid in a trench in rock, hard clay, shale or other hard material

the 15 cms depth below the pipe shall be excavated and refilled with an equalizing bed cushion of

15 cms thickness of granular approved granular soft murum, sand or compacted earth. In no case

the pipe shall be laid directly on such hard material. It should be ensured that the rock protrudes

shall be knocked off. When the pipes are laid completely above the ground the foundations shall

be made even and sufficiently compacted to support the pipeline without any material settlement.

Alternatively the pipeline shall be supported on rigid foundations at intervals as approved by the

Engineer-in-Charge. Suitable arrangements shall be made to retain the pipeline in the proper

alignment, such as by shaping the top of the supports to fit the lower part of the pipe. The distance

between the supports shall in no case exceed the length of the pipe. The pipe shall be supported

as far as possible close to the joints. In no case the joints shall come in the centre of the span.

Suitably designed anchor blocks at change of direction and grades for pressure lines shall be

provided where required. The cost of bedding below pipes, concrete and/or murum supports

constructed, anchor blocks etc. is not included in the scope of item and shall be paid separately

under relevant items included in the tender Jointing : Joints shall generally be of rigid type. Where

specified flexible type joints may also be provided, an approval of Engineer-in- Charge. Rigid

Spigot & Socket Joint : The spigot of each pipe shall be slipped home well into the socket of the

pipe previously laid and adjusted in the correct position. The opening of the joint shall be filled with

stiff mixture of cement mortar in the proportion of 1:1 (1 cement : 1 fine sand) which shall be

rammed with caulking tool and finished at 45° tapper. After a day’s work any extraneous material

shall be removed from the inside of the pipe and the newly made joint shall be cured at least for 7

days. Rigid Collar Joint : The two adjoining pipes shall be butted against each other and adjusted

in correct position. The collar shall then be slipped over the joint, covering equally both the pipes.

The annular space shall be filled with stiff mixture of cement mortar 1:1 (1 cement : 1 fine sand)

which shall be rammed with caulking tool and finished at 45° tapper. After a day’s work any

extraneous materials shall be

removed from the inside of the pipe and the newly made joint shall be cured at least for 7 days.

Flexible Spigot & Socket Joint : The joint is composed of specially shaped spigot and socket ends

on the concrete pipes. A rubber ring shall be placed on the spigot, which shall be 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 surfaces of the spigot and the socket. Flexible Collar Joint : This shall be

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

with a rubber ring which when compressed between the spigot and the collar, seal the joint.

Internal Flush Joint : This joint shall generally be used for culvert pipe of 60 cm diameter and

above. The ends of the pipe are specially shaped to form a self-centering joint with an internal

jointing space 1.3 cm wide. The finished joint shall be flush with both inside and outside with the

pipe wall. The jointing space shall be filled with cement mortar 1:1 (1 cement : 1 fine sand) mixed

sufficiently dry to remain in position when forced with a trowel or rammer and finished at 45°

tapper. After day’s work any extraneous materials shall be removed from the inside of the pipe and

the newly made joint shall be cured at least for 7 days. External Flush Joint : 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 1:1 (1 cement : 1 fine sand) sufficiently dry

and finished off flush at 45° tapper. Great care shall be taken to ensure that the projecting ends

are not damaged as no repairs can be readily affected from inside the pipe. In all pressure

pipelines the recess at the end of the pipe line shall be filled with jute braiding dipped in hot

bitumen or other suitable approved compound. Pipes shall be so jointed that the bitumen ring of

one pipe shall set into the recess of the next pipe. The ring shall be thoroughly compressed by

jacking or by any other suitable method.

The number of pipes that shall be jacked together at a time shall depend on the diameter of the

pipes and the bearing capacity of the soil, for small pipes upto 25 cm diameter, six pipes can be

jacked together at a time. The quantity of jute and bitumen in the ring shall be just sufficient to

fill the recess in the pipe when presses hard by jacking or by any other suitable method. Before

and during jacking care shall be taken to see that there is no offset at the joint.

Testing : Smoke test shall be carried out from chamber to chamber at contractor’s cost.

Refilling of Trenches : In case where pipes are not bedded on concrete special care shall be

taken in refilling trenches, to prevent the displacement and subsequent settlement at the surface

resulting in uneven surface and dangers to foundations etc. The back filling materials shall be

packed by hand under and around the pipe and rammed with a shovel and light tamper. This

method of filling will be continued upto the top of pipe. The refilling shall rise evenly on both sides

of the pipe continued upto 60 cm above the top of pipe so as not to disturb the pipe. No tamping

shall be done within 15 cm of the top of pipe. The tamping shall become progressively heavier as

the depth of the backfill increases (item of excavation shall be paid under relevant item of

supplied at site in stacks of approved size. When the metal is stacked in stacks of one uniform

size, smallest stack may be chosen in the particular km or unit section and measured for its length,

breadth and depth. The cubic contents of the stack shall be multiplied by the number of such

heaps in the km or unit section to arrive at the quantity in the particular km or unit section. The

Engineer-in-Charge may measure any other heaps also for verification. When the sizes of stacks

are not uniform, each stack shall be measured individually. The dimensions shall be measured

correct to two places of decimal of a meter and quantity worked out correct to two places of

decimals of a cubic meter. If there is reason to believe that the stacks are very loose and are

having unduly large hollows and or materials not satisfying the specifications, the stacks may be

got opened and restacked properly after removing the inferior material as directed by the

Engineer-in-Charge by the contractor at his cost. The measurements of such a stack shall then be

taken and if they are less than those of a normal stack, the quantity of the restacked stack shall be

multiplied by the no. of stacks to arrive at the quantity in the particular unit or length. No deduction

shall be made for voids. Metal shall not be used until the full quantity is collected in km or particular

unit and measured. All stacks measured shall be marked with lime wash bands to distinguish them

to avoid double measurement. If the material is found to be of inferior quality or of size not

satisfying the requirements, the same shall be rejected entirely. All labour, materials etc. required
