areas are not designated as borrow area, as discussed in the paragraph above and shall be left properly
leveled by the Contractor, so that it does not affect the subsequent use of the land for agriculture. If the
contractor leaves these areas unleveled, it will made good by the department at the cost of the
contractor.
T.S.-7

4.01 PREPARATION OF BORROW AREA:

All areas required for borrowing earth for embankment shall be cleared of all stumps rootshushes
rubbish and other objectionable materials. Particular case shall be taken to exclude all organic matter
from the materials to be placed in the canal embankment. All cleared organic materials shall be
completely burnt to ashes or disposed off as directed. Areas shall be maintained free of vegetable
growth during the progress of the work. No tree or standing crops are to be cut or destroyed.

4.02 STRIPPING OF BORROW AREA:

Borrow are shall be stripped off top soil sod and another materials which is unsuitable for the purpose of
filling. Stripping operation shall be limited only to designed borrow areas. Materials from stripping shall
be disposed in exhausted borrow areas of in the preparation of haul roads, cofferdarns, (for water
storage) etc or as directed by the Executive Engineer.

4.03 BORROW AREA WATERING:

Borrow areas watering will be doing wherever necessary. It shall be prepared by irrigating the
borrow area 48 hours in advance, so that materials may be carried with adequate moisture preferable at
O.M.C. determined for the particular type of soil by the laboratory.

The initial moisture content of materials in the borrow area shall be estimated with the help of
laboratory tests. The optimum moisture content for the materials in the particular borrow area shall be
obtained from the field laboratory. From the optimum moisture content and initial moisture content the
amount of additional water required shall be decided. The required additional moisture so decided shall
be introduced into the borrow area by watering well in advance of the excavation of ensure uniformity of
misture content. If in any location of a borrow area before or during excavation there is excessive
moisture, step shall be taken reduce the moisture closest to the optimum by excavation of drainage
ditches, by allowing adequate tune for drying for by any other means to aboard formation of pools in the
borrow area. During excavation operation drainage ditches from borrow area to the outlet shall be
excavated wherever necessary.

No extra a payment shall be admissible for stripping the borrow area of top soil etc as indicated.

Construction and maintenance of approach roads and haulage road will be the responsibility of

produce the practicable degree of compaction and ability. No excessive loads of materials than needed
for one layers shall be dumped on the earthfill so as to produce the best practicable distribution of the
materials. For this purpose the location in the earthfill where the individual loads shall be deposited with
a view to ensuring that the placed on the outer shoulders be decided earlier.

The movement of trucks, tippers shall be so guided that they do not pass along the same route,
otherwise no proper bond between successive layers will be achieved. The vehicle should have
separate to and from path of travel at the levels. Particular care shall be taken to ensure the materials
are not so placed as will be conductive to the formation of intermittent relatively impervious blankets in
the shall zones, which will interfere with the satisfactory drainage.

No stones, pebbles or rock fragments, having maximum dimension of more than 13 cms.(5”) shall be
allowed to get mixed with the earthfill. Such stones and pebbles shall be removed either at the borrow
pits or canal excavation before being transported to the embankments in any case this shall be removed
before materials in the earthfill are rolled and compacted. Such stones or pebbles shall be used in the
rip-rap or rock toe of the embankment it suitable or wasted as directed. The materials shall be placed in
the earthfill in the continuous horizontal layers, is not more than 22 cms. In thickness to be rolled to 15
cim. or minimum of specified proctors efficiency. The layers shall be so laid to avoid pools of water from
in the embankment due to rains. If it is felt that the rolled surface of any layer of earthfill is too dry or
smooth to bond properly with the layers of materials to e placed on it the same shall be moistened or be
worked with borrower, scarifier or any other suitable equipment, to a sufficient depth as directed
Engineer-in-charge, so as to provide satisfactory bonding before the next succeeding layer or earthfill
materials is placed. If the rolled surface of any earthfills found to be too wet for proper
T.S.-9

compaction of the layers of earthfill materials to be placed thereon, it shall be rocked up and allowed to
dry or be worked with borrower scarifier or any other suitable equipment to reduce the moisture content
to the required amount, and than it shall be compacted before the next succeeding layer of earthfill
materials is placed, when compacting the soil against step rock abutment or wells or masonry or
concrete structure and if the foundation surface is too irregular to allow the used of large roller directly
against a structure of rock out crop the large roller shall be used to compact the soil as close to the
structure of the out crop as possible and the portion of the embankment directly against the rock or the
structure shall be completed with pneumatic hand tempers within layers contents of the earthfill placed
against the rock or the structure shall be slightly above the optimum to allow it to be compacted in all
irregularities of the rock ad this shall be determined b the ield laboratory. In placing the earthfill or rock
foundation the foundation shall first be prepared as detailed earlier. Care shall be taken in placing the
first employed for compaction. The soil for the first layer shall be placed in embankment at moisture
content sufficient to enable satisfactory bonding of the fill with the bottom surface.

4.06 WEATHER CONDITIONS:

Embankment materials shall be placed only when the weather conditions are satisfactory to permit
accurate control of the moisture content in the Embankment materials, during shall be graded and rolled
with a smooth wheeled roller to facilitate run off. Prior to resuming work. The top surface shall be
scarified and moistend or allowed to dry as necessary and approved by the Engineer - in - Charge for
resumption.

4.07 MOISTURE CONTROL:

The water content of the earthfill materials prior to and during compaction shall he distributed uniformly
throughout earth layers of materials and shall he between 2 to 17 or the optimum moisture content.
Moisture determination of soils as well as needle moisture determination of soil shall be carried out as
per designation of E 9 and E-22 of USBR/Earth Manual (JULY 60). Laboratory investigation may impose
some restrictions on the lower limits of the practicable moisture contents on the basis of studies on
consolidation characteristic of soil in embankment. Hereinafter, the term range of optimum practicable
moisture content shall refer to the value as described above. As far as practicable the materials shall be
brought to the proper moisture content in the borrow the before excavation. If additional moisture is
greater than requires, the materials shall be spread and allowed to dry before starting rolling. Moisture
control shall be strictly adhered to. The moisture content shall be relatively uniform through out the layer
material. If necessary, ploughing. Disking, borrowing or blending with other materials may have to be
resorted to obtain uniform moisture distribution. If the moisture content is more or less than the range of
optimum and adding of further level shall be stopped. Further work shall be started again only when the
above conditions are satisfied.

T.S.-12
4.17 INSPECTION FAND TESTS:
It is necessary to maintain a through check on the quantity of fill materials delivered to the
embankment and that the data and in situ properties of the materials after compaction be obtained for
compairs on with design assumptions. To achieve these objective programme of fill testing and
inspection shall be planned to effect quality control.

4.17.1 SCOPE OF TESTING AND INSPECTION REQUIRED:

Field control of fill materials will require visual and laboratory checks. The check on the
effectiveness of placement and compaction procedures will require to be made by field density tests at
prescribed intervals. The control shall be both of the method type and or / on end result basis.

4.17.2 EMBANKMENT TEST SECTION:

Placement of compaction methods specified will have to be verified by test of an embankment section
for different zones to be built prior to start in fill operation or at an early stage of construction. Either the
initial stage of embankment construction itself could be mode to serve the purpose of test embankment
or test embankment or test embankments section could be established in borrow areas. The test
sections referred herein shall be used to materials.
a) Layer thickness of fill materials.
b) Optimum practicable moisture content.
c) Number of passes of sheep-foot roller, or weight of vibratory rollers Vis-a Vis number of
passes for effective compaction.
d) For pneumatic type compaction equipment, the test required will be such as to determine.
The most suitable ballast loding, tyre pressures, moisture contents and number of coverages
for compacting the materials in the zone.

When as appreciable change in materials occurs, additional rest sections should be made during
construction. He procedure for construction of test embankment section is as follows :

i) Select a location the embankment where additional test are being performed. The area
15 M x 30 M (about 50’ x 100’ ) should be carefully marked and referenced so that its
limits will be easily recognized. In order to expedite the determination of moisture content
to be used. More than one set section may be established on the embankment at the
same time.
ii) During construction of the test section which will most probably continue for several
shifts, a complete record of the procedure should be kept. This record should include the
number of layer placed and the spread thickness of each layer the moisture content at
which the materials were rolled, the designation (No 1, No 2 etc.) of the rollers used, the
conditions of the rolers (clean or dirty) condition of the materials being rolled such as
under the rollers, amount of penetration of the materials being same.

iii) Check the rollers to make certain that they meet all the requirements of the
specifications.
T.S.-13

iv) Determine the required spread layer that will compact to the specified thickness after
rolling specified number of ties and maintain this thickness as long as number of rollers
passes is kept the same.

v) Using the available data from borrow pit investigation of the materials to be used in the
test section, the optimum moisture content as determined by laboratory test will be known
and 3 percent less than this moisture content should be used in the 3 or 4 layers rolled.

vi) After 3 or 4 layers have been placed at 3% less than the laboratory optimum moisture
content, filed density test should be made throught the section. These test should be
made for at least each 93 sq. metres (1000 sq. ft.) of test section area and should be so
distributed over the area that they will detect the effects of different compaction
conditions encountered during construction for example of the section is located near
abutment certain parts of the area will receive more compaction form travel than others,
hence some tests should be made in the portion compacted only by the roller and as
reported.

vii) The next step is to compact another 3 to 4 layers at the moisture content slightly higher
(1% or 2%) than the moisture content previously used, maintaining the same rolled
thickness of layer density tests are again made over the test section

viii) If the resulting field dry densities (or material passing no 4 seive) from (vii) above show
an increase with increase of moisture than increases the moisture again by another 1%
or 2% and repeat the test. If an increase in moisture results in a decrease in field density
than place to next layers slightly dry of the original moisture content used and repeat the
test. This procedure is nothing more than developing on the embankment a moisture
density

ix) relation or compaction curve for a certain roller, thickness of layers and a given umber of
roller, passes it special studies during investigation have indicated that the materials
being tested should placed within certain moisture limits to be used have been specified.
The producers outlined above should include tests at these

x) moisture contents or a moisture contents both greater and smaller than the specified
limits

xi) The roller compaction corve is now compared with the standard laboratory compaction
curve. If the field density of materials passing the no. 4 sieve (from
the roller curve) is greater than the standard compaction density at the specified moisture
content the test section should be continued decreasing the number of roller trips while
maintaining the specified desirable moisture content until the most economical
compactive effect is determined when the roller strips are decreased, the required spread
thickness of layer than will compact to the specified thickness of compacted material
should be rekoned.

8.0 CEMENT CONCRETE WORK :
COMPOSITIONS :
Cement concrete shall composed of cement sand .Sand aggregate and water in prescribed
proportion by volume.The specifivcation for these materials have been given under this
chapter previously .
8.1BATCHING :
The concrete ingredient shall be provided in specified quanties by volumetric
measurements.When moist sand is used due allowance shall be made for bulking as
directed by the E/I .Appropriate means of correct measurmnet of the concrete ingredients
shall be provided means of correct measurement of the concrete ingredients shall be
provided to the satisfaction of the E/I .The proportions of mixes have indicated in the item
of work.
8.2 MIXING :
The more thoroughly a concrete is mixed ,the greater is its strength.The mixing shall
therefore be done in mixer only. Wherever the quantity involved shall and other
conditions do not permit the mix by mixer,hand mixing may be done with the specific
approval of the E/I or his authorised representatives,it will be necessary for the contractor
to arrange sufficient mixers for the desered concrete mix at the end mixing period .correct
proportion of materials shall be loaded in the mixing machines in accordance with water
cement ratio desired.It should thenbe kept rotating for 1.5 to 2 minutes till all materials are
mixed thoroughly and then concrete should be disposed in one operation over a level
platform and turned over one before being conveyed.Each time the work is stopped for the
day ,the mixer should be cleared out and when next mixing is commenced the first batch
should have10% additional cement to allow for stacking losses.
Whenever the quantity of mix is so small and hand mixing has been permitted by the E/I
the mixing shall be done on awter tight brick platform of edequate size approved by the
E/Iwith strip fastened along there side to prevent materials being washed or shoveled off
during mixing where hand mixing is allowed cement and sand shall first be mixed dry
thoroughly by turning over backword and forward several times.This day mortar shall
thenbe spread over the top of premeasured stack of dry aggregate .The whole batchshall
then be thoroughly mixed by turning over and ovewrbackword and forward atleast 5 times
to ensure through mixing.To this water shall then be added from fitted with
ratehole/gradually and the whole mass turned over and again till every stone materials is
sufficiently coated with mortar.No excess water should be used .The bulking shall be made
.The concrete prepared after mixing must posses a good consistency and workability in
case this is found deficient the ingredients will be adjusted to improve the same with
approval of the E/I or his authorised representative,slump test will be carried out regulary
to check consistency and workblity.Theslump should be specified by the E/I .
(T.S.-10)
8.3 SURFACE PREPERATION :
When concrete has to be laid in consecutive layer and sufficient time has lapsed between
first ccarse and successive one the lower course should be well racke,brushed with wire to
the satisfaction of E/I .All loose aggregates and lactances should be removed .To ensure
bond and water tightness between the old concrete surface and the concrete to be placed
the surface should od of initial green cut and sand blasting.The the green cut method
consists of rubbing the concrete surface with a high velocity air water jet accompanied by
wire brushing and jobbing,chipping,surface layer to expose clean surface of sound
concrete usually about 8to 12hours after placing.
If the initial clean up can not be performed at the proper stage in the hardening process
.All defective and desirable concrete will be removed by either chipping and picking by
hammer if so required or by sand blasting .Thereafter the entire surface shall be
thoroughly washed and should be dry to permit smooth cleaning .Ordinary sand may not
be used even for smaller work but sand of size 1.7mm to 4.75will be have to be
5.63kg./sq.cm.After sand blasting and washing is over ,the surface shall have to be got
approved by the E/I.and therefore covered with a 10mm to 20mm layer of mortar but care
shall be taken that mortar does dry up excessively thus loosing its consistency .
8.4 PLACING :
Concrete shall be placed in aplanned manner along the span so as to avoid cold joint.For
this process the contractor shall arrange sufficient labour ,materials ,tools and appliances
to complete the work in suitable blocks as programmed .
NO CONCERETE SHALL BE PLACED WITHOUT FORM WORK :
Before depositing the concrete debris of all the kinds shall be removed from the site of
concreting .The surface shall be well cleaned and brought to lines and levels as per
drawing and specification .No concrete shall be placed up till form work and placing of
reinforcement have been completed where required andchecked by the E/I according to
drawing and specification .There after mixed concrete shall be laid (not thrown) in
suitable layers and compacted with vibrator,suitable for the purpose and approved by the
E/I.
8.5 PLACING CONCRETE UNDER WATER :
Concrete is being placed under water ,unless placement .The dewatering operation should
be stopped at the time for placing of concrete ,extra cement up to 20% shal be added in
the concrete under water.The admixture shall be added in the concrete under water ,the
mix shall be suitable incrossed on the specific written approval of the E/I.The total
quantity of such concreting will have to be got recorded by the E/I or his authorised agent
so that a check may be kept on extra cement consumed .
8.6 COMPACTION:
As concrete is being placed it should be compacted thoroughly and uniformaaly
.Compacting includes rodding ,spading,vibrating and such other operation as are
necessary to compact the concrete properly ,concrete bshall be worked well around ther in
for cement enclosed fixture and corners of forms.
(T.S.-11)

Sufficient equprnet together with necessary operation should be provided atsite for
compaction .As concrete starts setting immediately after it is placed ,consolidation should
be done when placing is going on.Exessivevibration cauaing segregation and formation of
laitances shall be avoided .
HAND TAMPING :
16mm M.S. rods should be used for tamping. The tools should penetrate the full depth of
layer being placed and should used at or near virticalform faces.For dry hand tamped
concrete the surface should be rammed with heavy flats face trowel till a thin film of
mortar appears at the surface showing that air pockets have been filled.
VIBRATION:
Mass concrete should be thoroughly compacted with the aid of vibrators .Immediately
after placing concrete the vibrators should be started and operated for a few second .Then
moved to the other without any hole or impression of the vibrator ,vibration should be
continued till the
entire batch gives uniform appearance and surface just start to glist,vibrator should
beinserted and drawn slowly and operated continuously while being withdrawn ,it should
be in such a manner that no voids are lift in plastic concrete .
Sufficient number of vibrators should be used to compact each batch properly before
placing the next one .A sufficient number of reserve vibrators in good
conditions,concreting shall not be allowed to proceed without proper compaction with the
vibrator,suitable for the perpose.Under no circumstances the vibrator should stick the face
of forms not shall reinforcement steel or embaded metal be jerked with sufficient force to
empire the bond between concete and metals .
7. STOPPING WORK :
If for any reason it is necessary to stop conreting in the middle of ajob,it should be
stopped as under:
FOR SLAB :
In a vertical plane at right angles to the span either middle span over the centre of the
supporting beam or girder .
FOR COLUMN :In horizontal at right angles to the length of the column.
FOR BEAM AND GIRDER :In vertical plane at right angle to the length of the beam or
girder either the mid span or over the centre of the support of the beam .In no case shall
the work be stopped in beams of slab where futureshearing action will be great as for
example near the end or direct under concentrated load.At place other than specified
above,should become necessary to stop cocreting for any unforeseen reasons,the same
shall be done at the locations directed by the E/I.In all such xases the edges of the
concrete shall be left and finished in a proper slope as per direction of the E/I.
Before commencing the work ,surface of the existing concrete must be carefully brushed
with stiff brush to remove particules and dust thick grout of neat cement must be poured
over it before new concrete is placed.
8.8 CURING AND PROTECTION OF CONCRETE :
The object of curing is to prevent or replenish the loss necessary of moisture during the
early relatively rapid stage of hydration .Minimum curing period for the concrete shall be
21 days and is to commence as
soon as the concrete has harened but not before that 24 hours the time of placement .The
curing shall be accomplished by keeping the exposed surface continuously moist
condition.
Where forms are used these shall be kept sprinkled with water until removal.Wooden
forms may be loosened wetted thoughly at frequent intervals so that water floods the
space between the forms and concrete .Merely having form in place will not keep the
concrete sufficiently moist for proper curing .When spray pipe system is used for
spraying,galvanized or alloy pipe shall be used .This will prevent rust stain that may be
formed by use of iron pipe.Construction joint shall be continuously kept wet for atleast 72
hours prior to the placing of additiona concretes.All water used in curing sall be free from
excessive amount of silt and other impurities.
8.9 TESTING :
The contractor shall provide all lanour required for making and cube test specimens
without any separate payments. 8.10 CLASSIFICATION :
Except where required to meet special conditions ,all concrete shall confirm to the
classification in the table given below defined according to maximum aggregate size arld
other approximate details.The mix proporations may have to be modified after detailed
laboratory test and field experiment.These mixes may fyrther be modified to suit the work
or the nature of materials used further be modified to suit the work or the nature of
materials used.The contractor’s rates are to bebased on the concrete of mixes of required
strength and quantity of cement specified in the table below. The vibrations in ingredients
will not be considered for adjustment in rates .

Finishing of concrete and also of providing and fixing supports ,contrivances and form
work along with removal there of including the the surface preparation for the next lift
and removal and making good the damage concrete as required .The unit of measurement
will be per cubic meter .
8.12 FORM WORK :
a) The turm form work ,shall include all forms sheeting,planks,poles,shores,ties,upright
and all other temprory supports to the concrete during the process of laying and
setting.The form work shall be of such dimension ,strength and rigidity and so constructed
as to hold the concrete and to with stand the necessary pressure and remain rigid during
the laying ,vibration and setting of concrete without any deflection from the prescribed
lines.The joints must be water tight and smooth so as to prevent leakage cement slurry.All
faces wich will come in corncrete with the concrete must be plain ,clean,rigid,tightand
smooth,suitable devices shall be used to hold the corners djacent ends and edge ofpanels
or other forms together in accurate alignment.The form shall be such as to produce finish
of striking of at one.
b) Where wooden forms are the lapping shall be in the direction of the structures as shown
in the drawing or as directed of E/I..Wood sheating or lining shall be of such a kind and
quality or shall be so treated ,that there shall be not chemical deterioration or declaration
of the formed concrete surface.
c) FORM MATERIALS &CONCRETE SURFACE : All timber used shal be of the
best quality,sound straight,freee from sap,loose knots,warps holes and other defects
seasoning is of great importance partiality seasoned
timber is tom be best for from work,since if it is to dry it will tend to small from
absorption of moisture while green timber is to be best for form work,since if it is to dry
it will tend to small from absorption of moisture while green timber will try to dry out and
shrink in hot weather causing elevation and depression in the concrete .All timber faces
coming in contact with concrete should be made plans to give better finish of the concrete
face.The form work should have sufficient strength and rigidity.
d) METAL FORMS : Metal forms shall b epermitted for permanently exposed surface
.Curves and special forms shall be character that will result on smooth concrete surface
.They shall be so designed and constructed that they will not warp or spring during
eraction or placing concrete .Forms to be used more than one shall be maintained in
scecable condition and will be the thoroughly cleaned and smoothened in the forms with
the minim,um amount of bumps or other impe,factions.The use of sheet metal be correct
imperfections in the lining of lumper faced forms for surface that be permanently exposed
to view will not be permitted.
TIMES : The use of metal rods and other similar divices in the concrete for holding forms
will be permitted if the ends of rods are omitted or subsequently removed to a depth of
not less than 50mm from the surface of the concrete without injury to the concrete
provided that for walls to be subjected to water pressure on side and to be water tight ,the
rods shall not be continuous through the wall.Removal of embedded rods shall not be
permitted .Removal of embedded fastners on the ends of the rods shall be such as to leave
of regular share for ramming .All hole left by the removal of fastners from the in of the
rods shall beimmediately rammed with suitable to end remers ,so as to leave the surface of
the hole clean and rough and completely filled with dry patch mortar and the surface
finished to meet adjustment concrete .Wire ties shall be permitted only when specifically
approved and shall be cut flusts with the surface of the concrete after the form are
removed .Wire ties shall not be used where permanent exposed finish surface are required
.
(T.S.-14)
e) OILING : All forms coming in contact with concrete should be oiled with cured oil
perferbly before being set in place .This oiling allows easy stripping of forms as the
concrete does not stick to the oily form ,if the concrete is to be place ,however,oil should
not be used as it prevents the adhesion of plaster ,wetting with water of soft soap and
water will sufficient in such cases,In no case the reinforcement placed over the form work
should be oiled.

f) ERECTION OF FORMS : Before placing of concrete ,is placed ,precaution shall be

taken to see that all forms are in proper alignment and that forms anchors and ties are
thoroughly the form strips for narrow groove so as to prevent reeding of the forms
subsequent damaged to concrete prior to the removal of forms where form for continuous
surfdace are placed in successive units ,the forms shall fit roughly over the completed
surface so as to prevent leakage of mortar from the concrte and to maintain accurate
alignment of the surface .
g) Removal of forms should never be started until the condrete is thoroughly set and has
attained to give it sufficient strength to carry its own weight besides the live load.which is
