3.6.1 Diversion :

If diversions barricading and signals are found to be necessary, they

shall be provided as directed by Engineer.

3.6.2 Preparing the ground for laying bank :

Before any material is laid for the bank the ground shall be cleared of all

rubbish etc. and the holes if any, filled up. When the embankment is to

be laid on hill sides 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. 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 if directed and

compacted to the same density as specified for the embankment before

any material is laid for the bank-work.

202

When the embankment is to be placed over an existing road or other

hard surface 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.

The rate for embankment includes all the operations for preparing the

bed for laying the bank.

3.6.3 Laying the bank :

Embankment material shall be placed in successive horizontal layers of

20 cm. to 30 cm. depth, extending to the full width of the embankment

including the slopes at the level of the particular layer 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 later after completion of the

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

Keeping the 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 will remain loose and uncompacted. Similar

procedure to extend the embankment by dumping the material

longitudinally shall also not be allowed. When placing the bankwork in

20 cm. to 30 cm. layers is not feasible as in water or over slopes too

steep to operate the construction equipment, the embankment may be

constructed in one layer to the minimum level at which equipment can

be operated and above such a level, the embankment shall be made up

in layers of specified thickness. 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 into the bank

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, levelled and compacted as specified hereinafter, before the

succeeding layer is placed. The surface of the embankment shall, at all

Page 89: CIDCO OF MAHARASHTRA LIMITED, CBD-BELAPUR, NAVI …cidco.maharashtra.etenders.in/tpoimages/cidco/tender/Tender187.pdfcidco of maharashtra limited sl.pg.no. c.a.no. 01/cidco/se(p&k)/ee(klm-ii)/2012-13

CIDCO OF MAHARASHTRA LIMITED Sl.Pg.No. C.A.NO. 01/CIDCO/SE(P&K)/EE(KLM-II)/2012-13

203

times during construction, be maintained at such a cross fall as will shed

water and prevent ponding. If bridges and culverts on the road are not

completed in advance of bankwork, a length of 15 m. to 30 m. bank

shall be left on each side of the structure and these lengths shall be dealt

with later for placing the bank work.

3.6.4 Watering :

If the bank material contains less than the optimum moisture water shall

be added to the material in the borrow pits or alternatively in the loose

layers of the embankment to bring the moisture uniformly upto

requirement. If some moisture is likely to be evaporated in transit or in

the bank before compaction adequate water in excess shall be added to

allow for the loss. If the material contains more than the required

moisture, it shall be allowed to dry until the moisture is reduced to the

required extent. If due to wet weather etc., the moisture content of the

soil cannot be reduce to the appropriate amount by exposure, bank

work shall be suspended till suitable conditions prevail without

contractor's claiming any compensation.

Water to be used shall be free of from harmful elements which may

cause heavy efflorescence etc., and approved by the Engineer. The

contractor shall make his own arrangement for getting adequate

quantity of acceptable water.

3.6.5 Compaction :

When a loose layer is levelled manually of mechanically and moistured

or dried to a uniform moisture content suitable for maximum

compaction, it shall be compacted by power roller, sheeps foot rollers or

vibratory roller or heavy hauling or dozing equipment to give the

specified 95%/97% of the Modified Proctor density for respective item

specified under Schedule “A”. If on testing, the density is found to be less

than 95%/97% of the Modified Proctor density the contractor shall do

Page 90: CIDCO OF MAHARASHTRA LIMITED, CBD-BELAPUR, NAVI …cidco.maharashtra.etenders.in/tpoimages/cidco/tender/Tender187.pdfcidco of maharashtra limited sl.pg.no. c.a.no. 01/cidco/se(p&k)/ee(klm-ii)/2012-13

204

additional compaction necessary to get the specified density after adding

water if required. It the density can not be improved on reasonable

efforts, the work may be accepted as substandard by the Engineer, if he

thinks it not harmful for the purpose, at a reduce rate. Where the

specified density is imperative the work shall be removed and redone by

the contractor at his own cost to give the specified density.

Where the material allowed to be used is excessively stony or sandy so

that it will not compact to the required density where such material is

otherwise acceptable for embankment construction the Engineer may

waive the tests for stony or sandy portions where the required test results

are contained. Each layer shall be compacted fully before the next layer

is laid.

Proper sequence of all component operation shall be maintained to give

individual progress.

To all for subsequent settlement, the finished level or of the embankment

may be kept higher than the specified level by 1 cm. for each metre of

the height of the bank and this, if provided, will be paid for.

The hauling equipment, animals, labour etc., shall be made to go

over the bank as far as possible, to get the initial compaction. Care

shall be taken for getting good compaction behind abutments returns

and wings walls, etc.

Bank-work in areas not accessible to rollers such as those adjoining

bridges, culverts and other work, shall be carried out independently of

the main embankment and shall be have the layers placed in 10 cm.

to 15 cm. (about 4" to 6") height and each layer shall be moistened

and thoroughly compacted with mechanical or manual tampers.

Embankment shall be brought up simultaneously in equal layers on

each side and compacted carefully to avoid unequal pressure etc.

and compaction of the bank-word 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 diversion of streams,

local surface drainage, rain water etc. likely to damage the bank.

Any damage to the bank-work due to no protection or inadequate

protection shall be made good by the contractor at his own cost.

manufactured at site, weigh batching plant or obtained from

approved R.M.C. supplying agencies is mandatory. The R.M.C.

supplying agency will supply mix design details in advance before

start of delivery.

6.2 Transporting, placing, compacting, finishing and curing :

Transporting, placing, compacting, finishing and curing of concrete shall

be in accordance with IS:456-2000.

Page 97: CIDCO OF MAHARASHTRA LIMITED, CBD-BELAPUR, NAVI …cidco.maharashtra.etenders.in/tpoimages/cidco/tender/Tender187.pdfcidco of maharashtra limited sl.pg.no. c.a.no. 01/cidco/se(p&k)/ee(klm-ii)/2012-13

CIDCO OF MAHARASHTRA LIMITED Sl.Pg.No. C.A.NO. 01/CIDCO/SE(P&K)/EE(KLM-II)/2012-13

211

6.2.1 Transporting :

For all RMC concreting, the concrete after discharge from batching plant

will be loaded in transit mixers and kept continuously agitated while mix is

in transit. At destination the mix will be unloaded in to the hoppers of

concrete pump. For site made concrete suitable prescribed methods shall

be adopted.

6.2.2 Placing :

The concrete produced in RMC plant/batching plant, when discharged

from transit mixer in pump hopper shall be kept continuously agitated

and pumped to destination placing point. Site made concrete shall be

placed by approved method of placing. The height of any single lift of

concrete shall not exceed 1.5 m for walls and 2.0 m for columns. For

columns where the height of pour is more than 2.0 m, suitable

arrangement in formwork should be made so that the vertical drop of

concrete is restricted to less than 2.0 m. Any such arrangement should be

approved from the Engineer in advance before execution.

High velocity discharge of concrete causing segregation of mix shall be

avoided. The concrete shall be placed in the forms gently and not

dropped from the height exceeding 1.5 m except in columns where the

maximum allowed will be 2.0 m. Each batch of concrete will be placed

in layer. Each layer of concrete shall be compacted fully before the

succeeding layer is placed and separate batches shall be placed and fully

compacted before the layer immediately below has taken initial set. The

layers should be sufficiently shallow, to permit stitching of two layers

together by vibration.

Concreting of any portion or section of the work shall be carried out in

one continuous operation and no interruption of concreting work will be

allowed without approval of the Engineer.

Plain concrete in foundations shall be placed, in direct contact, with the

bottom of excavation, the concrete being deposited in such a manner, as

212

not to get mixed with the earth. The concrete placed below the ground

level shall be protected from falling earth during and after placing.

Concrete placed in ground containing deleterious substances, shall be

kept free from contact, with such ground and with water draining there

from during placing and for a period of 7 days or otherwise instructed

there after. Approved means shall be taken to protect immature concrete

from damage by debris, excessive loading, abrasion, vibrations,

deleterious ground water, mixing with earth and other materials and

other influences that may impair strength and durability of concrete.

Before starting of work, contractor will get the concrete pouring

programme and its sequence approved by Engineer to avoid cold joints.

6.2.3 Compaction :

External, Internal (needle) and surface (screed board) vibrators of

approved make shall be used for compaction of concrete

a) External/internal vibrators shall be used for compaction of

concrete in foundations, columns etc. For sections such as slabs,

the concrete shall be compacted by external, internal and surface

type vibrators, depending on the thickness of layer to be

compacted. 25mm, 40mm and 60mm dia internal vibrators may

be used. The concrete shall be compacted by use of appropriate

diameter vibrator by holding the vibrator in position until :

b) Air bubbles cease to come to surface ii) Resumption of steady

frequency of vibrator after short period of dropping the frequency,

when the vibrator is first inserted.

  c)   The tone of the vibrator becomes uniform Flattened, listening

surface, with coarse particles blended into it, appears on the

surface.

d) Aggregates: After the compaction is completed, the vibrator

should be withdrawn slowly from concrete so that concrete can

Page 99: CIDCO OF MAHARASHTRA LIMITED, CBD-BELAPUR, NAVI …cidco.maharashtra.etenders.in/tpoimages/cidco/tender/Tender187.pdfcidco of maharashtra limited sl.pg.no. c.a.no. 01/cidco/se(p&k)/ee(klm-ii)/2012-13

213

flow in to the space previously occupied by the vibrator. To avoid

segregation during vibration, the vibrator shall not be dragged

through the concrete nor used to spread the concrete. The vibrator

shall be made to penetrate into layer of fresh concrete below if

any, for a depth about 150mm. The vibrator shall be made to

operate at regular pattern of spacing. The effective radii of action

will overlap, approximately half a radius to ensure complete

compaction.

e) To secure even and dense surfaces free from aggregate pockets,

vibration shall be supplemented by tamping or rodding by hand in

the corners of forms and along the form surfaces while the

concrete is plastic.

f) A sufficient number of spare vibrators shall be kept readily

accessible to the place of deposition of concrete to assure

adequate vibration in case of breakdown of those in use.

g) 25mm diameter immersion vibrators shall be used in thin sections

upto 125mm, 40mm diameter immersion vibrators in fairly wide

sections like beams, slabs, columns etc. and 60mm diameter

vibrators in foundations, pilecaps or such large section members.

Screed vibrators shall also be used for slab concreting.

h) Plain concrete also shall be vibrated whenever and wherever

directed by EIC to achieve full compaction, using needle and

screed vibrators as necessary.

6.2.4 Curing :

Curing shall be started at the earliest by spreading wet jute cloth (hessian)

and cover top with impervious sheet and subsequently cured with

spraying water. In inaccessible area to start with, curing be started by

spraying curing compound before starting membrane curing.

6.3 Placing temperatures :

During extreme hot weather, the concreting shall be done as per

procedures set out in IS:7861, Parts I & II.

Fine and coarse aggregates for concreting shall be kept shaded and the

concrete aggregates sprinkled with water for a sufficient time before

concreting, in order to ensure that the temperature of these ingredients is

as low as possible prior to batching. The mixer and batching equipment

shall be also shaded and if necessary painted white in order to keep their

temperatures as low as possible. The placing temperature of concrete

shall be as low as possible in warm weather and care shall be taken to

protect freshly placed concrete form overheating by sunlight in the first

few hours of its laying. The time of day selected for concreting shall also

be chosen so as to minimize placing temperatures. In case of concreting

in exceptionally hot weather the Engineer may in his discretion specify the

use of ice either flaked and used directly in the mix, or blocks, used for

chilling the mixing water. In either case no extra payment shall be made

to the contractor on this account.

6.4 Construction joints :

Construction joints in all concrete work shall be made as directed by the

Engineer. Where vertical joints are required, these shall be shuttered as

directed and not allowed to take the natural slope of the concrete.

Before fresh concrete is placed against a vertical joint, the old concrete

shall be chipped/sand blasted, cleaned and moistened 25 hours before

placing the concrete. All standing water should be removed and dried

with compressed air. Neat cement slurry shall be applied on the

chipped/sand blasted surface and mortar of the same water cement ratio

as the concrete and 10mm thick applied. Where required suitable

expansion joints shall also be provided as directed by the Engineer.

The time of day selected for concreting shall also be chosen so as to

minimize placing temperatures. In case of concreting in exceptionally hot

Page 101: CIDCO OF MAHARASHTRA LIMITED, CBD-BELAPUR, NAVI …cidco.maharashtra.etenders.in/tpoimages/cidco/tender/Tender187.pdfcidco of maharashtra limited sl.pg.no. c.a.no. 01/cidco/se(p&k)/ee(klm-ii)/2012-13

weather the Engineer may in his discretion specify the use of ice either

flaked and used directly in the mix or blocks used for chilling the mixing

water. In either case the cost of ice either flaked and used directly in the

mix or blocks used for chilling the mixing water. In either case the cost of

ice and additional labor involved in weighing and mixing etc. shall be

borne by the contractor and nothing will be paid on this account.

6.5 Defective Concrete:

Should any concrete be found honeycombed or in any way defective,

such concrete shall on the instruction of the Engineer be cut out by the

Contractor and made good at his own expenses.

6.6 Exposed Faces, Holes and Fixtures :

On no account shall concrete surfaces be patched or covered up or

damaged concrete rectified or replaced until the Engineer or his

representative has inspected the works and issued written instructions for

rectification. Failure to observe this procedure will render that portion of

the works liable to rejection; in which case it will be treated as a work

which has failed to meet specified strength requirements.

Holes for foundation or other bolts or for any other purposes shall be

moulded, and steel angles, holdfasts or other fixtures shall be embedded,

according to the drawing or as instructed by the Engineer.

6.7 Cracks :

6.7.1 If cracks develop in concrete construction which in the opinion of the

Engineer may be detrimental to the strength of the construction, the

contractor at his own expense shall test the slab or other construction as

specified in Special Conditions. If under such test loads the cracks

develop further, the Contractor shall dismantle the construction, carry

away the debris, replace the construction and carry out all consequential

work thereto, without any extra payment.

6.7.2 If any cracks develop in the concrete construction, which in the opinion of

the Engineer, are not detrimental to the strength of the construction, the

contractor at his own expense shall grout the cracks with polymer cement

grout of approved quality at his own expense and risk and shall make

good to the satisfaction of the Engineer the surface finish which in the

opinion of the Engineer has suffered damage either in appearance or

Attempts should be made to obtain the 30 test results, as early as

possible, when a mix is used for first time.

Standard deviation to be brought up to date. The calculation of the

standard deviation shall be brought up to date after every change of mix

design and at least once a month.

6.10.1.6 Determination of Standard deviation :

Concrete of each grade shall be analyzed separately to determine its

standard deviation.

The standard deviation of concrete of a given grade shall be calculated

using the following formula from the results of individual tests of concrete

of that grade obtained as specified in table.

Estimated Standard deviation = S = 2

n – 1 Where : = deviation of the individual test strength from the average

strength of ‘n’ samples and n = Number of samples test results.

When significant changes are made in the production of concrete

batches (for examples changes in the materials used, mix design,

equipment or technical control), the standard deviation value shall be

separately calculated for such batches of concrete.

6.10.1.7 Assumed Standard Deviation :

Where sufficient test results for a particular grade of concrete are not

available the value of standard deviation given in table – 8 of IS : 456 of

2000 may be assumed.

221

adequacy of the parts affected shall be investigated and any

consequential action as needed shall be taken.

Concrete of each grade shall be assessed separately.

Concrete shall be assessed daily for compliance.

Concrete is liable to be rejected if it is porous or honey combed, its

placing has been interrupted without providing a proper construction

joint, the reinforcement has been displaced beyond the tolerances

specified, or construction tolerances have not been met. However, the

hardened concrete may be accepted after carrying out suitable remedial

measurement to the satisfaction of the Engineer.

6.10.2 Failure To Meet Specified Requirements :

If from the cube test results it appears that some portion of the works has

not attained the required strength, the Engineer may order that portion of

the structure be subjected to further testing of any kind whatsoever as

desired by the Engineer including, if so desired by him, full load testing of

the suspected as well as adjacent portions of the structure as specified in

the conditions of contract. Such testing shall be at the contractor’s cost.

The Engineer may also reject the work and order its demolition and

reconstruction at the contractor’s cost. If the strength of concrete in any

portion of the structure is lower than the required strength, but is

considered nevertheless adequate by the Engineer so that demolition is

not necessary, the contractor shall be paid a lower rate for such lower

strength concrete as determined by the Engineer.

6.10.3 Testing Of Concrete :

The contractor shall erect at site a suitable laboratory at his cost for

routine testing of materials, testing of materials, testing of concrete cubes

etc. the samples of materials used in the work, tested materials as well as

laboratory at all times and shall produce on demand complete records of

all tests carried out on site.

Before concreting commences on any section of the works the contractor

shall obtain approval of the Engineer or his representative as regards the

form and reinforcement conforming with the drawings. He shall also

indicate to the Engineer in writing and obtain his approval for positions of

construction joints. The Engineer or his representative’s approval shall

not relieve the contractor of any of his obligations to comply with the

provisions of this specifications or contract.

6.10.4 Admixtures :

Approved admixtures and air entraining agents may be permitted by the

Engineer at his discretion provided that the strength requirements and

durability are not affected by their use.

6.10.5 Slump Test :

weight Batching plant and transported to the job in agitating transit

mixer.

The maximum size of coarse aggregate shall be limited to one-third of

the smallest inside diameter of the hose or pipes used for pumping.

Provision shall be made for elimination of over-sized particles by

screening or by careful selection of aggregates. To obtain proper

gradation it may be necessary to combine and blend certain fractional

sizes to aggregates. Uniformity of gradation throughout the entire job

shall be maintained.

The quantity of coarse aggregate shall be such that the concrete can be

pumped, compacted and finished without difficulty.

6.12.2 Fine aggregates :

The gradation of fine aggregate shall be such that 15 to 30 percent

should pass the 0.30 mm screen and 5 to 10 percent should pass

0.15mm screen so as to obtain a pumpable concrete. Sands that are

deficient in either of these two sizes should be blended with selected finer

sands to produce these desired percentages. With this gradation, sands

having a fineness modulus between 2.4 and 2.8 are generally

satisfactory. However, for uniformity, the fineness modulus of the sand

should not vary more than 0.2 from the average value used in

proportioning.

6.12.3 Water, Admixtures and slump :

The amount of water required for proper concrete consistency shall take

into account the rate of mixing, length of haul, time of unloading and

ambient temperature conditions.

Additions of water to compensate for slump loss should not be resorted to

nor should the design maximum water-cement ratio be exceeded.

Additional dose of retarder/plasticizer/superplasticizer shall be used with

prior approval of Engineer to compensate the loss of setting time and

slump at contractor’s cost. Retempering water shall not be allowed to be

added to mixed batches to obtain desired slump.

6.12.4 Transportation :

The method of transportation used should efficiently deliver the concrete

to the point of placement without significantly altering its desired

properties with regard to water-cement ratio, slump, and homogeneity.

The revolving-drum truck bodies of approved make shall be used for

transporting the concrete. The number of revolutions at mixing speed,

during transportation, and prior to discharge shall be specified and

agreed upon. Reliable counters shall be used on revolving-drum truck

226

They should be nominally rated for at least 3.5 Mpa pressure and greater

for rising runs over 30 m. Couplings should be designed to allow

replacement of any section without moving other pipe sections, and

should provide full cross section with no construction or crevices to disrupt

and smooth flow of concrete.

All necessary accessories such as curved sections of rigid pipe, swivel

joins and rotary distributors, pin and gate valves to prevent backflow in

the pipe line, switch valves to direct the flow into another pipe line,

connection devices to fill forms from the bottom up, extra strong

couplings for vertical runs, transitions for connecting different sizes of

pipe, air vent for downhill pumping, clean-out equipment etc. shall be

provided as and where required. Suitable power controlled booms or

specialized crane shall be used for supporting the pipe line.

6.12.6 Field control :

Sampling at both truck discharge and point of final placement shall be

employed to determine if any changes in the slump and other significant

mix characteristics occur. However, for determining strength of concrete,

cubes shall be taken from the placement end of line. The RMC supplier

should nominate a technically qualified representative at site for

sampling, testing and placing of concrete.

6.13 Planning :

Proper planning of concrete supply, pump locations, line layout, placing

sequence and the entire pumping operation shall be made. The concrete

production, transportation and placing shall be planned in such a

manner that duration between addition of water during mixing and

placing of concrete in desired location is well within time limits prescribed

by the RMC manufacturer, however, this is subjected to fulfillment of

slump and other properties of concrete as specified in tender. On failure

to adherer to the time schedule by the supplier the Engineer may reject

the concrete.

227

The pump wherever used should be as near the placing area as

practicable, and the entire surrounding area shall have adequate bearing

strength to support concrete delivery pipes. Lines from pump to the

placing area should be laid out with a minimum of bends. For large

placing areas alternate lines should be installed for rapid connection

when required. Standby power and pumping equipment should be

provided to replace initial equipment, should breakdown occur.

The placing rate should be estimated so that concrete can be ordered at

an appropriate delivery rate.

As a final check, the pump should be started and operated without

concrete to be certain that all moving parts are operating properly. A

grout mortar should be pumped in to the lines to provide lubrication for

the concrete, but this mortar shall not be used in the placement.

When the form is nearly full and there is enough concrete in the line to

complete the placement, the pump shall be stopped and a go-devil

inserted and shall be forced through the line by water under pressure to

clean it out. The go-devil should be stopped at a safe distance from the

end of the line so that the water in the line will not spill into the placement

area. At the end of placing operation, the line shall be cleaned in the

reverse direction.

SUBMISSION OF DOCUMENTS FROM RMC MANUFACTURER

Following document shall be submitted by the RMC manufacturer to

CIDCO through the contractor

should be taken to ensure close fitting joints against the steel bars

so as to avoid loss of fines during the compaction of concrete.

3) If the formwork is held together by bolts or wires, these shall be so

fixed that no iron will be exposed on surface against which

concrete is to be laid. In any case wires shall not be used with

exposed concrete formwork. The Engineer may at his discretion
