g) From humps above the general ground level within the road land.
h) From land acquired temporarily if any, outside the road land
i) From borrow pits in Departmental land when permitted and from
non Departmental and private lands when necessary.
The contractor shall follow the priorities fixed by the Engineer for
obtaining the materials from different sources.
All lifts and leads involved in conveying the materials to site shall be
included in the rate except when the materials from road cutting or other
excavation being paid separately are to be conveyed for use in banks
with different leads.
If the materials are to be obtained from non-Departmental and private
lands, the contractor shall make his own arrangements and be
responsible for payment for rents, compensation, royalty etc. and shall
not be entitled for extra claims.
The Department shall remain indemnified regarding any claims that
may be made by private owners in this respect.
If all the useful materials available from the road cutting are not used
and materials obtained from other sources are used instead by the
CIDCO OF MAHARASHTRA LIMITED Sl.Pg.No. C.A.NO. 01/CIDCO/SE(P&K)/EE(KLM-II)/2012-13
201
contractor for his own convenience, such materials shall be deemed to
have been obtained from the road cutting to the extent to which useful
materials were available for bank and shall not be paid for under this
item.
3.5 EQUIPMENT S :
Pickaxes, crowbars, phawras and pans may be used for manual work.
Scrapers, dozers, graders, shovels, dumpers, trucks, trolleys etc. may be
used for mechanised work. Three wheel 8 tonne power roller or
sheepsfoot roller giving a pressure required to obtain the specified
density may be used for compaction. Bullock carts with tanks or
mechanically driven tankers may be used for watering.
3.6 CONSTRUCTION METHOD :
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.
CIDCO OF MAHARASHTRA LIMITED Sl.Pg.No. C.A.NO. 01/CIDCO/SE(P&K)/EE(KLM-II)/2012-13
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
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

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
CIDCO 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

6.1 Batching of Concrete ingredients :
For all structural concreting, only Ready Mixed Concrete (RMC)
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.
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
CIDCO OF MAHARASHTRA LIMITED Sl.Pg.No. C.A.NO. 01/CIDCO/SE(P&K)/EE(KLM-II)/2012-13
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
CIDCO 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
CIDCO OF MAHARASHTRA LIMITED Sl.Pg.No. C.A.NO. 01/CIDCO/SE(P&K)/EE(KLM-II)/2012-13
215
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 :

6.7.2 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
stability owing to such cracks. The Engineer’s decision as to the extent of
the liability of the Contractor in the above matter shall be final and
binding.
6.8 Finishes :
Unless otherwise instructed the face of exposed concrete placed against
formwork shall be rubbed down immediately on removal of the formwork
to remove irregularities. The face of concrete for which formwork is not
provided other than slabs shall be smoothed with a float to give a finish
equal to that of the rubbed down face, where formwork is provided. The
top face of a slab which is not intended to be covered with other materials
shall be leveled and floated to a smooth finish at the levels or falls shown
on the drawings or as directed. The floating shall be done so as not to
bring as excess of mortar to the surface of the concrete. The top face of a
slab intended to be surfaced with other materials shall be left with a
spaded finish. Face of concrete intended to be plastered shall be
roughened by approved means to form a key.

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

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 :
Only sufficient amount of water shall be added to the cement and
aggregates during mixing to produce concrete having sufficient
workability to enable it to be well consolidated to fill up the corners of
shuttering and to work around the reinforcement and to give specified
surface finish and to have the specified strength.
The slump of concrete shall be determined from time to time by carrying
out slump tests. For vibrated concrete slump shall range from 2.5 cm To
CIDCO OF MAHARASHTRA LIMITED Sl.Pg.No. C.A.NO. 01/CIDCO/SE(P&K)/EE(KLM-II)/2012-13

should be tested in CIDCO laboratory or approved by Engineer at
contractor’s cost.
6.12 Ready-Mixed Concrete and Pumping Concrete
6.12.1 Ready-mixed concrete may be manufactured in a central automatic
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.
CIDCO OF MAHARASHTRA LIMITED Sl.Pg.No. C.A.NO. 01/CIDCO/SE(P&K)/EE(KLM-II)/2012-13
225
6.12.3 Water, Admixtures and slump :
The amount of water required for proper concrete consistency shall take

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
units. Standard mixer uniformity tests, conforming to ASTM standards C
94-69 “Standard Specifications for Ready Mix Concrete”, shall be carried
out if desired by Engineer to determine whether mixing is being
accomplished satisfactorily.
6.12.4 Pumping of concrete :
Only approved pumping equipment, in good working condition, shall be
used for pumping of concrete. Concrete shall be pumped through a
combination of rigid pipe and heavy-duty flexible hose of approved size
and make. The couplings used to connect both rigid and flexible pipe
sections shall be adequate in strength to withstand handling loads during
erection of pipe system, misalignment, and poor support along the lines.
CIDCO OF MAHARASHTRA LIMITED Sl.Pg.No. C.A.NO. 01/CIDCO/SE(P&K)/EE(KLM-II)/2012-13
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.
CIDCO OF MAHARASHTRA LIMITED Sl.Pg.No. C.A.NO. 01/CIDCO/SE(P&K)/EE(KLM-II)/2012-13
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
