2.4.4 Excavation may be carried out by manual labour or by excavating machine.

2.4.5 EXCAVATION IN ROCK :

Excavation in rock shall be such that all sharp points of rock are chipped off so asnot to extend into the canal profile. Blasting in a manner which is likely to produce overbreakage which in the opinion of Engineer-in-charge in excessive, shall not be permitted.Special care shall be taken to prevent over breakage, or losening of materials on bottomand slopes. Excavation in excess of the prescribed canal section shall not be permittedbeyond pay line and no payment will be made for such excess excavation.

2.4.6 The materials excavated in a chain of 20/30 meters shall be stacked on either sideof the chain as specified on the drawing or as directed by the Engineer-in-charge

2.4.7 The excavation shall be carried out according to the dressing with accuratelygraded bed fall and sides properly sloped as shown in the drawings and as directed bythe Engineer-in-charge. The cross section adopted in cutting is likely to change in sideslopes according to the depth of different strata during actual excavation. The Contractortherefore should get clear instructions from Engineer-in-charge, before commencing anycutting work.

No claims for any variations in quantity of excavation resulting from the deviationfrom the instructions of the Engineer-in-charge, would be accepted. To account for this,the central box cutting with the canal bed width as its width have to be taken to canal bedlevel first, before the side slopes are determined and attacked (except for deep cutting of

108 -


more than 6 m depth). In portions where deep cutting of more than 6 m. is to be done, themode of excavation to be followed must be got approved from the Engineer-in-charge,before starting the work in such reaches and in any case, width of excavation to betackled initially shall not be more than bed width + depth.

The excavation should initially be carried out in steps. The steps should have suchwidth and depth that after they are cut, the required final slopes is attained. Cutting ofsteps should be done after bed level is reached and after one monsoon. If cutting is insoft strata , cutting of steps should be done just prior or preparing the side slopes forlaying lining.

2.4.8 REMOVAL OF LOOSE ROCK ETC :

Before any work of excavation is taken up, all loose rock, semi-detached rock in/orclose to the areas to be excavated that is liable to fall or otherwise ending the workmenon the project shall be stripped. The method employed shall be such as will not shatter ortender unstable and therefore unsafe any rock that was originally sound or safe. Anymaterial not requiring removal as contemplated herein, but which may later becomeloosened or unstable portion shall be promptly and satisfactorily removed, The cost ofsuch clearing shall be deemed or have been included in the unit rates accepted under thediffernt items under excavation.

2.5.0 CLASSIFICATIONS :2.5.1 The classification of strata shall be as under:

i) SOFT STRATA :

This shall include all kinds of rock or shale, indurated clay.soil.slit sand and gravel,soft murum, and hard murum, and any other material which can best be removed with ashovel after loosening with a pick axe and /or bar.lt shall also include isolated boulders upto 0.1 cubic meter each, which does not need blasting and could be removed with a pickbar and shovel.

ii) HARD STRATA :

This shall include all rock occurring in masses which could be removed by blastingwhere such blasting is permissible. It shall also include rock by means of chisels orwedges, it shall also include boulders in mass and insulated boulders over 1.0 cum eachwhich requires blasting or wedging and breaking for easy removal. Merely the useexplosive in excavation shall not be considered a reason for classification in the hardstrata unless regular blasting is clearly necessary in the opinion of the Engineer incharge. The hardness of strata or material to be excavated, presence of different type ofgeological constituents requiring increased drilling efforts, consumption of explosive,labour and use of machinary shall not be considered as reason for claim/increase incontract rates.While excavating in hard strata , if soil seams are struck, they will be considered as partof hard strata if the depth of individual seams is upto 15 cm.

2.5.2 In case of the disputes over the classification of strata met with during execution,the decision of the Engineer-in-charge will be final;2.5.3 PAYMENT LINE ( PAY LINES):

109 -


The minimum excavation line is the line within which no unecavated portion of anykind shall be allowed to remain i.e. neat profile line for unlined and underside of the liningproposed is any for works of canal and disnet.Payment shall be made for the work done as per the paylines prescribed in various strataand side slopes as below.

2.5.3.1 FOR SIDES :

excavation and back fill shall be limited to 30 cm average, if any overcuts are morethan this limit, no payment for additional overcuts and backfill will be paid for.

In case, excavation beyond minimum line of excavation (i.e. underside of lining) is in between 0 to 10 cm payment, for backfill with C.C. (1:3:6) proportion shall belimited to average 5 cm for payment, and will be executed monolithically withC.C.(1:3:6) side lining.

In case the excavation exceeds the above limit of average of 5 cm. the extrawork involved of backfill shall be carried out by the Contractor at his cost or he shallhave options for backfilling with chip masonary of 20 cm. minimum thickness at hisown cost.

b) In case of canal excavation with side slopes 1:1 in hard strata , pay line of10 cms. shall be permitted for payment of exacavation and backfill with C.C.(M-IO)

c) In case of canal exacavation with side slopes 1:5; 1 & above in hard stratapay line upto 10 cm. shall be permitted for payment .of exacavation and backfill withchip masonary in cm (1:10). In case the average exacavation beyond minium line ofexacavation is upto 5 cm. backfill shall be done with C.C.(M-IO). Apart from thestandards given above for the pay lines, the Cotractor shall take care to see that theslopes are stable and no accidents or slips would occur.

Tolerance for overcut beyond pay lines arising out of peculiar nature of rock atthe site and other site conditions shall be decided by the Superintending Engineer-in-charge of the work. Payment for exacavation beyond pay lines upto tolerance lines insuch specific cases shall be made @60% rate of the particular item of the work. Notolerance shall however be permitted in soft strata.

2.5.3 FOR BED:Payline in case of bed shall be 10 cm. Extra exacavation in bed beyond

110 -


measured under respective items. Murum filling will be paid under item of casing fromquarry or excavated stuff.

EXCAVATION IN HARD STRATA :

2.5.4.2 While excavating in hard strata , if softness are struck, they will be consideredas part of hard strata if the depth of individual seams is upto 15 cm. When depth ofsoft seams is more than 15 cm. it will be paid under item of soft strata.

2.6.0 MAINTENANCE OF SLOPES IN EXCAVATION :

2.6.1 Any shoring and strutting required during excavation and afterwards shall bedeemed to be covered by the rates quoted for the items.

structure or its part. Where there is abrupt change in depth additional cross sections may

be taken at the discretion of the Engineer-in-charge. Levels along the cross sections shall

be taken at every 1 5 to 20 meters or 5 meters as per necessity of work.

During the excavation of the work, running payment for the items of excavation

will be made to Contractor at 90 percent of his tendered rate for the item. The remaining

payments for these items shall be progressively released depending upon the progress of

completion of the item of excavation. This part rate will be reviwed by the Engineer-in-

charge when he feels necessary and decision of the Engineer-in-charge shall be final and

3.6.0 WATERING AND COMPACTION :

3.6.1 Compaction of bank shall be done by 8 to 10 tones vibratory rollers. Before con-

solidation, the layer will be moistered with adequate quantity of water to bring the percent-

age of O.M.C, with variation of (+ or-) 2 % of O.M.C. The rate of the item includes

charges for rolling and for providing sprinkling water with all leads and lifts required for the

purpose. Before laying the next layer the previous layer shall be scrapped and picking

done if required so as to ensure good bond with the new layer. Subsequent layer shall

only be allowed after the first layer is satisfactorily consolidated. If contractor fails to give

required compaction, the Corporation shall employ additional rollers at contractor's cost.

The hearting and casing shall be raised simultaneously in order that the whole

embankment may be raised evenly.

3.6.2 The compaction will have to be uniform over the full width of the bank. The vibra-

tory roller should be made to travel over the entire design section of each layer so that the

earth is fully consolidated and leaves no visible marks on the surface or as directed by

the Engineer-in-charge. Where, smooth rollers are used, the surface of each layer of

compacted material shall be roughened with a horrow and throughly borrowed or raked

before depositing the succeeding layer of material and care shall be exercised to avoid

128 -


the occurrence of horizontal seams. Earth work should be continuous from day to day. In

An allowance shall be made for surface moistureperesent in the aggregate while computing water content as indicated in I.S. 456-2000.

The ingredients of concrete shall be properly mixed in mixers, designed so as to

positively ensure uniform distribution of all the component materials through the mass, at

the end of the mixing period. The mixing of each batch shall continue about one and half

to two minutes depending upon the revolutions per minute of the mixer and experience

after all materials, except for the full amount of water are added in the mixer. The mini-

mum mixing period specified above assumes proper control of the rotation of the mixer

and of introduction of the materials, including water. The mixing time shall be increased at

the discretion of the Engineer-in-charge when the charging operation fails to produce

concrete of the required uniformity of composition and consistency within the batch and

140 -


from the batch to batch, contractor shall not be entitled for, any extra payment for such

increase in mixing time Excessive mixing requiring the addition of the water to preserve

the required concrete consistency shall be avoided. If the mixing and charging operations

are such that the required uniformity of the concrete is obtained in shorter mixing time

than the minimum specified without sacrifice of needed workability, the mixing time may

be shortened under orders of the Engineer-in-charge. Mixing shall be done by mechanical

menas only.

Materials corresponding to one bag mix or half bag mix (depending upon the

mixer capacity) shall be placed in the skip in sequence of metal, cement and sand. The

skip shall then be emptied into the drum and specified quantity of water added to material

in drum.

The following general principles shall be followed in operation of mixing.

a) The ingredient shall be fed into the mixer simultaneously.

b) A portion of water (between 5 and 10 percent) shall follow introduction of the

materials. The remainder of the water shall be added uniformly and simultaneously with

the other materials.

b) Care shall be taken that mixing of concrete in the mixture shall be uniform.

4.9.1 CEMENT :

The cement shall be produced as per para 14 of Special Conditions of Contract instandard bags as received from the manufacturer and shall conform with thespecifications, laid down by the Bureau of Indian Standards (vide their specifications No.I.S. 269 of 1976) for Portland cement and I.S.I, (vide there specification No. l.S. 1489-1976 and subsequent revision) for pozzolana cement.

4.9.2 ADMIXTURE :

Admixtures such as curing compound, air entraing agents etc. shall be addedafter the approval of Engineer-in-charge. The A.E.A., as on admixture, shall beadded to the concrete batch in solution in such a manner as will ensure uniformdistribution of admixture throughout the batch during the specified mixing period ofabout 2.5 minutes. The amount of A.E.A. shall be such as to effect of about 5% air inthe mix in order to have good work ability and thus secure as good finish of concretelining.

4.10.2 PRELIMINARY LABORATORY TEST :The Preliminary tests of cubes shall be carried on in the laboratory well in

advance of commencement of work. These tests should indicate an adequate marginover the stipulated specified in para 4.10.1

4.10.3 WORKS TESTS ON CONCRETE :

Tests for crushing strength shall be made on standard cubes as per the relevant

Indian standard specifications. For works tests, samples shall be taken on the job as and

when directed. For works tests, samples shall be taken once for every 30 cubic meter of

each type of concrete laid and at least three times a day, if output is more than 75 cubic

meter. The sample for work test is defined as a set of three cubes. The materials required

for the samples (Concrete, cement, sand and coarse aggregate) shall be supplied by

contractor free of cost and collection of samples, casting of cubes and transportation of

samples for testing from site to laboratory shall be done by contractor at his cost and

testing shall be carried out by the Contractor at his own cost.

4.10.4 STANDARD OF ACCEPTANCE :

Not a single sample of work test cubes shall have at the age of 28 days, a

crushing strength less than the stipulated crushing strength of concrete. The Engineer-in-

charge may at his discretion occasionly accept crushing strength of a sample, which is

less than the stipulated strength but which is equal to or more than 85 % of the stiuplated

strength. Each sample of work test cubes shall assume to present 30 cum. concrete and

142 -


corresponding quantity of concrete showing crushing strength less than stipulated

strength shall be paid at reduced rates as under :

1) Equal to or more than 95 % At full rates in occassional cases.

2) Equal to or more than 5 % reduced rate90 % but less than 95 %

3) Equal to or more than 10 % reduced rate.85 % but less than 90 %

The reduced rate shall be approved by the Superintending Engineer.

If the crushing strength falls below 85 % of the stipulated crushing strength then

the quantity of concrete represented by these samples will not be paid for. Defective

parts, if noticed shall be removed and redone by the contractor at his cost. Unit for accep-

tance of these tests will be one working season In addition to the 28 days strength test,

the Engineer-in-charge may, at discretion take 7 days strength test and / or 3 days

(accelerated curing) strength test and fix up the relation between such strength and 28

days strength after studying the actual values realised. If at any time the test i.e. 7 days or

3 days (accelerated curing

strength indicates that the strength may not be achieved as specified by the Engineer-in-

charge, he shall have authority to suspend the work of laying concrete until the reasons

for low strength have been investigated and corrected. The Contractor shall comply with

such suspension until the reasons for the variations are investigated and corrected and

such suspension shall not be accepted as reason for any claims. The Engineer-in-charge

may at his discretion also order suspension of the work when the variation in the strength

of the individual work test cubes from average of the set is in his opinion excessive. The

Contractor shall comply with such suspension until the reasons for the variations are

investigated and corrected and such suspension shail not be accepted as reason for any

claim.

The average crushing strength shall not be less than stipulated crushing strength

for each nominal mix .

4.10.5 SLUMP TESTS :

In order to test the consistency of the mixed concrete, slump test shall have to be

made by the Contractor when and where required by the Engineer-in-charge as per

IS:1199 . The allowable slump shall be decided by the Engineer-in-charge, depending

143 -


upon the location of the concrete. For Canal Lining, slump range 50-65 mm is considered

adequate. It can be increased upto 75 mm, if considered necessary in particular situation

for practical usage.

4.10.6 In the case of reinforced concrete work, the workability shall be such as theconcrete wil! surround and properly grip all the reinforcement. Water cementratio will be such as will give concrete just sufficiently wet to be placed andcompacted without difficulty.

4.10.7 Concrete shall have a consistency such that it will be workable in the requiredposition and in the case of R.C.C, flow around reinforcing steel also.

4.10.8 For vibrated concrete slump shall range between 2.5 cm to 5 cm. The slumpshall be determined as detailed in Appendix 'G' of !.S. 456-2000 and maintained throughout the concreting operation of a member.

4.11.0 FORMS :

4.11.1 GENERAL:

Forms to confine the concrete and shape it to the required line shall be usedwherever necessary. The form shall have sufficient strength and rigidity to hold concreteand to withstand the pressure of ramming and vibration without excessive deflection fromthe prescribed lines, the more so when the concrete is in vibration. The Contractor shallhave to get the design and drawing of the centering approved from the Engineer-in-charge before erection. Form work for concrete shall be of any of the following types.

a) Wooden shuttering with steel plates lining or plywood shuttering.

b) Steel shuttering.

For works costing more than Rs. One crore, only steel shuttering to be used.However as per need of site, wooden shuttering would be allowed only if it is free warpingand is fabricated true to line and shape. The decision of the Engineer-in-charge as to thesuitability of wooden shuttering as per (a) above to be used by the contractor will be finaland binding on the Contractor. The surface of all forms in contact with concrete shall beclean, rigid, watertight and smooth. Suitable devices shall be used to hold corners,adjacent ends of panel of other forms together in accurate alignment.

4.11.2 DESIGN :

The detailed designs of the form work and false work shall be prepared by theContractor and got approved by the Enpineer-in-charge well in time. Such an approvalhowever, will not relieve the Contractor of his responsibility for the adequacy and strengthof the form work and false work.

144 -


Forms shall be as designed and constructed as to be removable in sectionswithout damaging the surface of the concrete and with facilities of removal in ascendingorder without disturbing the remaining forms required to be removed later.

4.11.3 MATERIAL:

The forms and false work shall be made of wood or metal. The timber from which

the forms are prepared should preferably be partially seasoned. It shall be free from sap,

shakes, loose knots, worm holes or other defects. The planks and scantlings shall be

sawn straight and all edges and planes shall be straight and free from warps. Partially

seasoned soft wood is generally preferable for form work as it is difficult to drive nails in

hardwood. The dimension of scantlings should conform to the design. The strength of the

wood shall not be less than that assumed in a design.

In metal forms, steel sheets of the designed gauge strenghened with framing ofangle or other section shall be used.

Wooden forms may also be lined within thin steel sheet or plywood to give therequired surface or finish.

4.11.4 FABRICATION :The timber planks and scantlings of the designed dimensions shall be used in the

form work with appropriate spacing of studs, yokes, joists, girders etc. as provided in the

designs. All timbers in contact with concrete shall be brought on one

face and two edges, the unbrought face being on the outside. The joints should be

made mortar tight. This may be done either by providing tongued and grooved or riveted

joint or by caulking or nailing to the construction operations. The nuts and bolt heads

inside the form work adjoining the concrete should be countersunk, The form work should

allow finished concrete to have a smooth surface and conform to the shapes, lines and

dimensions shown on the plans and true to line and grade. Tiie effect of vibrations shall

betaken into account in the design and fabrication of the form and false work.

4.11.5 TREATMENT OF THE INNER SIDES OF FORMS :Before placing concrete, the inner sides of the forms, which come in contact with

the concrete, shall be coated with mineral oil or any other suitable materials approved by

the Engineer-in-charge which will prevent adhesion of concrete to the forms but will not

discolor the concrete. When oil is used, it shall be applied before reinforcement is placed.

145 -


Care shall be taken to see that reinforcement does not come in contact with coating. All

chipping, saw dust and other rubbish shall be removed from the interior of the forms

before concreting.

4.11.6 FALSEWORK :

False work shall be build on foundation or base of sufficient strength to carry theloads without settlement. False work can not be found on solid footing must be supportedby piles or other similar devices. False work shall be designed to carry the full loadsincluding that due to construction operation coming upon it.

4.11.7 ERECTION AND REMOVAL OF FORMS :

The false work and form work shall be erected with an eye for absolute safety ofthe form work and concrete work before and after pouring concrete. Watch should bekept to see that the behavior of centering and form is satisfactory during concreting.Erection should also be such that it would allow removal of forms in proper sequencewithout damaging either the concrete or the forms to be removed later.

If there is failure of false work and / or form the Contractor shall be responsible forall the consequent damages to work, injury to life and damage to property and make goodthe damage at his cost.

i) Before placing concrete the suface of forms shall be oiled with a suitablenonstaining oil such as raw linseed oil so as to prevent sticking of concrete and facilitateremoval of form.

ii) The oil shall cover the fomrs fully and evenly without excess over drip. Careshall be taken to prevent oil from getting on surface of the construction joints onreinforcement bars. Special care shall be taken to oil thoroughly the forms strips fornarrow grooves so as to prevent swelling of the forms and consequent damages toconcrete prior to or during removal of forms. Immediately before concrete is placed, careshall be taken to see that all forms are in proper alignment and the support and fixture arethoroughly secured and tightened.

iii) Where forms for continuous surface are placed in successive units, the formshall fit tightly over the completed surface so as to prevent leakage of mortar from theconcrete and to maintain accurate alignment of the surface.iv) Forms shall be left in place until their removal is authorised and shall then be removedwith care so as to avoid injury to concrete.

v) Removal of forms shall never be siarted until the concrete is thoroughly set andhardened adequately to carry its own weight beside the live load which is likely to comeon work during construction. The length of time for which the forms shall remain in placeshall be decided by the Engineer-in-charge, with reference to weather conditions, shapeposition of the structure or structural member and the nature and amount of dead and fiveloads.

In normal circumstances forms shall be struck after the expiry of the followingperiod.

a) Walls, columns and vertical faces 24 to 48 hrs. as may be decided

146 -


of all structural members by the Engineer-in-charge

b) Slabs (props left under) 3 days

c) Beam soffits (props left under) 7 days

d) Removal of props under slabs

1) Spanning upto 4.5 m. 7 days

2) Spanning over 4.5 m. 14 days

e) Removal of props under beams and arches

1) Spanning upto 6 m. 14 days

2) Spanning over 6 m. 21 days

NOTE : The number of props left under and their size and disposition shall be

such as to be able to carry the full dead load of the slab, beam or arch as the case may

be together with any live load likely to occur during curing or further construction.

In no case shall forms be removed until there is assurance that removal can be

accompanished without damaging the concrete surface. No loads will be allowed to dam-

age the concrete surface. Heavy load shall not be permitted until after the concrete has

reached its desighed strength. The forms shall be removed with great caution and without

harming the structure or throwing heavy forms upon the floor.

4.11.8 RE-USE OF FOMRS ETC. :

Forms required to be used more than once shall be maintained in serviceable

conditions and shall be thoroughly cleaned and smoothened before reuse. Where metal

sheets are used for lining forms, the sheets shall be placed and maintained on the forms

with minimum amount of wrinkles, humps or other imperfections. All forms shall be

checked for shape and strength before reuse.

4.11.9 INSPECTION :

The forms and false work will be inspected, checked and approved by theEngineer-in-charge before concreting commences. But this will not relieve the Contractorof his responsibility for strength, accurancy and safety of the form and false work.

4.12.0 PLACING CONCRETE :

147 -


4.12.1 Concrete shall be placed only in locations where authorised and no concrete ormortar shall be placed until form work, installations of embedded parts, preparation ofsurface or necessary clean up has been approved.

4.12.2 ROCK SURFACE :

Rock surface upon or against which concrete is to be placed, shall be prepared asspecified in section of excavation for foundation.

4.12.3 MASONRY SURFACE :

i) Masonry surfaces on which or against which concrete is to be placed shall beprepared as per specifications. The unit rate for masonry shall cover the cost of suchpreparation.

ii) If the old layer of masonry which has been paid for is required to be removedas mentioned, it shall be back filled with concrete along with upper concrete layer at noextra cost.

4.12.4 CONCRETE SURFACES :

Before laying of concrete the surface of the concrete in day to day work shall be

cleaned by a wire brush and jets of water, so that the surface is thoroughly cleaned and

wetted, but pools of water are avoided. If the old concrete surface has remained exposed

for more than two weeks, it shall be prepared got roughened by chipping to a depth of two

centimeters and the surface coated or covered with a layer of cement mortar (1:2) for a

depth of 5 to 8 cm. The unit rate of concrete shall cover the cost of such preparation and

also of the cost of cement mortar, The concrete removed for roughening shall not be paid

for.

4.12.5 ALL SURFACES:

i) The cleaned rock, masonry or concrete surface shall be applied with cementslurry and then cement mortar coat as mentioned.

ii) The first few batches of concrete may, if required, contain half the regular sizeof coarse aggregate without any extra claim.

iii) The cost of such preparation work stands included in the unit rate of cementconcrete.

4.12.6 TIME FOR USE :

148 -


All concrete shall be placed directly in its final position within thirty minutes ofmixing. Any concrete which has become so stiff that proper placing cannot be assuredwithout retempering shall be wasted and shall not be paid for. All surface of fomrs andmetal work including reinforcement bars that have become encrushed with dried mortar ofgrout concrete previously placed shall be cleaned of all such mortar or grout beforesurrounding or adjacent concrete is placed.

4.12.7 METHOD OF PLACEMENT :

Before starting placing of concrete, it should be made ceratin that the transporting

and placing equipment is clean in proper order and that equipment along with the

operating staff is arranged to deliever the concrete in the final positions without undue

delays and objectionable segregation. The methods and the equipment used for transport

and placing of concrete shall be such as will permit the delievery of concrete of the

required consistency into the work without objectionable segregation, porosity or

excessive loss of workability. Excessive segregation from whatever cause shall be

prevented in handling and placing operation by avoiding or controlling lateral movement

of the concrete as in dumping at an angle depositing continuously at one point and

allowing the concrete to flow. Concrete shall not be dropped from excessive heights and

free fall should be kept to a minimum. Concrete shall be deposited continuous horizontal

layers in a thickness of approximately 30 cm. in normal work to 45 cm for mass concrete

except that nothing herein shall be constructed to permit placement of the additional

horizontal layers of mass concrete before the entire area to be concreted is covered by

previous layers. On flat, horizontal surfaces where congestion of steel near the forms

makes placing of concrete difficult, mortar of the same cement, sand ratio as used in the

concrete shall be first deposited to cover the forms and shall stand included in unit rate of

concrete before the entire area to be concreted is covered by previous layers.4.12.8 RATE OF PLACING :

Concreting should be continued without interruption until the structure or section iscompleted or until satisfactory construction joints can be made. Location of constructionjoints shall be as directed by the Engineer-in-charge. Concrete shall not be placed, fasterthan the placing crew can compact it properly. In placing the thin members and columnsprecautions shall be taken against too rapid placement which may result in movements orfailure of the forms due to excessive lateral pressure. An interval of at least 12 hrs. andpreferably 24 hrs. should elapse between the completion of columns and wall and theplacing of slabs, beams, or girders supported by them in order to avoid cracking due tosettlement. All concrete shall be placed in approximately horizontal lifts not exceeding1.25 m. in thickness per day. Concrete in arches shall be done in strips extending fromone pier to another. No through joints shall be kept in the span.

4.12.9 CONCRETING AT NIGHT TIME :

149 -


If concrete to be placed at night adequate lighting arrangements shall be made, asdirected by the Engineer-in-charge.

4.12.10 CONCRETING DURING RAINS :

When concerting is required to be done or continued while it is raining it shall beseen that the concrete is not damaged due to rain while it is being transported andplaced. After placing the green concrete it shall be adequately covered for a period of 24hours when it will be capable for being cured by splash of water. The surface of freshconcrete should be maintained on a slope sufficient for result in the self drainage of therain water. The work shall however be discontinued when the rain is so severe that watercollects in pools or washes the surface of the fresh concrete and it is not possible toprovide adequate shelter.

4.13.0 COMPACTION :

4.13.1 GENERAL:

In all concrete works, required numbers of vibrators, with stand by in workingcondition will be kept ready at site as per instructions of the Engineer-in-charge.

4.13.2 All concrete shall be vibrated by mechanical vibrator of approved type so as

to ensure dense concrete. Hand tamping and rolling shall not be used for compaction of

concrete except in special circumstances with the prior permission of the Engineer-in-

charge. When immersion type vibrators are used they shall be used vertically at about 45

cm. apart The vibrators shall be inserted to the full depth of the newly laid concrete layer.

The concrete shall be thoroughly compacted during depositing to get a dense concrete

and thoroughly worked into the edges and corners of the form work and also along its

faces and around reinforcement in the case of R. C. C. by means of suitable tools such

as trowel, rods to get a good finish

without honeycombing. The vibrator shall however not re-vibrate concrete which has

commenced its final set. Special care shall be taken to see that the vibrator touching the

reinforcement of embedded part does not disturb the concrete below which has

commenced its final set. The concrete shall not be vibrated excessively so as to cause

segregation.

4.13.3 Each layer of concrete, for surfaces which is required to be smooth and for allsurfaces which will be permanetly exposed to weather, and for all surfaces next to em-bedded metal work shall be worked and vibrated by mechanical vibrator of approvedtype, only so as to obtain a concrete of maximum density and imperviousness and toassure close contact of the concrete with forms, reinforcement bars and other embeddedparts. If the methods of transporting and placement have been conductive toairentrainment, segragation of stiffening, the work or compaction should receive specialattention.

150 -


4.13.4 For concrete surfaces exposed to flow of water special precaution shall be takento minimise and to prevent surface pitting and protrusions without resorting to overmanipulation of the concrete mix to thefomrs. No plastering forgetting a smooth finishedshall be permitted at these locations. Any protrusion shall be ground smooth.

4.10.0 CURING AND PROTECTION :

All concrete shall be protected against injury until final acceptance. Exposedfinished surface of concrete shall be protected from the direct rays of sun of at least 72hrs. after placement. Concrete shall be kept continuously moist for not less than 21 days.Constructions joints shall be cured in the same ways as other concrete and shall also bekept moist for at least 72 hrs, prior to the placing of additional concrete upon the joints.Approximately horizontal surfaces shall be cured by sprinkling, pounding or by covering,or by damp sand or by cured by the use of wet quilts or mats. Vertical surfaces shall becured by covering with wet jute bags. If damp sand or quilting is used for curing, it shallbe removed completely later. Should the concrete that has become dry or powderthrough neglect of curing the contractor shall rectify the work at his own extra cost. Ifcuring arrangements by the contractor are not satisfactory, the Engineer-in-charge may inhis discretional engage labour and provide material and equipment for curing and recoverexpenditure thus involved from contractor.

4.15.0 FINISHING :

4.15.1 GENERAL:

Finishing of formed and unformed surfaces shall be performed only by skilledworkmen. All exposed concrete surface shall be clean of all in incrustations of cementmortar or grout. Unsightly stains shall be removed.

4.15.2 FORMED SURFACES :Surface of concrete finished against form shall be smooth, free from projections

and filled thoroughly with mortar. Immediately upon removal of forms, all unsightly ridges

or fines shall be removed and any local bulging on exposed surfaces shall be remedied

by tolling and rubbing. All holes left by the removal off fasteners shall, after being reamed

with toothed reamer, neatly filled with dry patching mortar. Ail porous and fractured con-

crete and surface concrete to which addtions are required to bring it to the prescribed

lines shall be sharp edged and keyed and shall be filled to the required line with fresh

concrete used for filling shall be reinforced and dowelled to the surface of the opening.

Honey combed surfaces and which give a hallow sound shall be rectified by guniting at

the Contractors cost within the unit rate accepted for concrete.

151 -


4.15.3 DRY PATCHING:Dry patching mortar shall consist one part of cement and two parts of sand by

volume and just enough water so that the mortar so used will together on being moulded

into a ball by a slight pressure of hands and will not exclude water when pressed but will

leave the hand damp. The mortar shall be placed in layers of not more than 2 cm. thick-

ness. After being compacted each layer shall be roughened by being scratched to provide

an effective bond with succeeding layers. The fast of finishing layer shall be smooth to

form a surface continuous with the surrounding concrete. All patches shall be bonded

thoroughly to the surface of the chipped opening and shall be sound and free from shrink-

age cracks.

4.15.4 FINISHING PERMANENTLY EXPOSED SURFACE :Except as otherwise specified or directed all permenently exposed concrete

surface and other waterway surface requiring durability under water (except the outlet)

shall be finished in the following manner. Immediately upon removal of the form, the

surface shall be wetted and all surfaces pits and air bubbles filled by rubbing mortar

composed of cement and fine sand in proportion (1 : 2) into the pits with burlap so as to

secure a normally dense and smooth face.

The rubbing shall be performed in such a manner as to leave the surface free

from mortar not used for filling the pits. Should the filling operation be unduly delayed and

the surfaces of the pits become coated with dirt or other contaminating mateials, they

shall be thoroughly cleaned and washed and shall be maintained in a moist condition,

until the mortar filling is placed. Such cleaning should be done by means of air and water

jets and chipping or brushing or other satisfactory means

without damaging the surrounding concrete. All operations in connection with the filling of

surface pits shall be handled as practicable to minimize the period during which the

concrete and mortar filling are exposed to the drying when the treatment of surface has

been completed. Surfaces shall be neat and of the same colour and texture as the

adjoining concrete.

4.15.5 FINISHING CONCEALED SURFACE :

For exterior concealed surfaces below ground or backfill level or like surfaces nototherwise specified, no finish is necessary except that sand streaks, metal pockets,honey combing or other imperfections which are of consequence affecting strength, watertightness or protection of reinforcing steel from corrosion shall be corrected and repairedas prescribed for formed surface.

152 -


4.15.6 FINISHING UNFORMED SURFACE :

Unformed surface shall be finished by one more of the operation of scribbling

floating and trowelling of the surface should be done at proper time employing experi-

enced men and should be just suffucient to produce the desired finish. Scribbling which

gives the surface its approximate shape by striking off surplus concrete immediately after

compaction shall be accomplished, by moving a straight edge or template with a sawing

motion across wood or metal strips that have been established as guides. Where the

surface is curved special screed should be brought true to form and grade by working it

with a wooden float, if a coarse textured finish is desired or if the surface is to be steel

troweled a section or final floating should be performed after some stiffening has occured

and the surface moisture film or shine has disappeared. Where smooth dense finish is

desired floating shall be followed by steel trowelling some time after moisture film or shine

has disappeared from the floated surface and where the concrete has hardened

sufficiently to prevent fine material and water from being worked out t he surface.

Excessive trowelling particularly at early time shall be avoided.

4.15.7 CHIPPING AND ROUGHENING CONCRETE SURFACE :

Surface upon or against which additional concrete is to be placed shall be chipped

and roughened to a depth not greater than 25 mm. Roughening shall be performed by

chipping or other satisfactory methods and in such manner as not to loosen, crack or

shatter any part of the concrete beyond the roughened surface. After being roughened

the surface of the concrete shall be cleaned thoroughly of all loose fragments, dirt and

other objectionable substances and shall be sound and hard in such conditions as to

assure good mechanical bond between old and new concrete. All concrete which is not

hard, dense and durable shall be removed to the depth required to secure a satisfactory

surface.

4.15.8 DAMAGE DUE TO FLOODS-CORPORATION NOT RESPONSIBLE :

In case of damage of any of the concrete works due to floods, Corporation will not

be responsible and whatever corrective measures are required to be adopted shall be

done by the Contractor at his cost.

4.17.0 PAYMENT:

4.17.1 Payments shall be on the net quantity of concrete after deducting quantities foropenings and other class of work. No decutions shall be made for anchor bars,reinforcement, grout holes and bore or weep holes or any opening not exceeding 100square centimeters in cross section. Rate shall be subject to paragraph 4.10.4 above.Measurements of concrete shall be taken within the specified pay lines for the structure orad indicated on the drawings. Any concrete placed in the excavation beyond the line ofstructures to avoid use of forms, shall not be paid for.

SECTION-19

F – FORMWORKSCOPE:

This item includes providing formwork as per drawing and design to withstand the

pressure of tamping and vibration without excessive deflection, including all labour

and materials etc. complete.

19.1 GENERAL

Forms shall be used, wherever necessary, to confine the concrete and to shape it

to the required lines. Normally all exposed concrete surfaces having slope steeper

than 2 horizontal to one vertical shall be formed.

The condition of forms influence not only appearance of the structure but also

quality. Use of good form material and proper form construction and maintenance

is very important in field control. The use of steel form work enhances the

appearance of placed concrete. It should be recognized that it is not particularly

economical to use poor quality form. Too often any savings from use or injudicious

re-use of poor timber form, are compensated by manual labour in repairs for final

dressing of the structure to an acceptable appearance.

19.2 WORKMANSHIP, CLEANLINESS AND STRENGTH OF FORM WORK.19.2.1 The form work shall be of steel, timber forms shall not be allowed.

Supports shall also be of steel. Suitable wedges in pairs be provided to facilitate

adjustment and subsequent releasing of forms. The contractor shall furnish the

details of his proposed form work to the Engineer-in-charge for his approval

before erection there-of.

19.2.2 All rubbish, particularly chippings, shavings, saw dust and grout etc. shall

be removed from the interior of forms before these are erected. Cleanliness of

forms shall be again checked after the forms are in place and before the concrete

is placed. The face of the form work, which is to be in contact with the concrete

shall be cleaned and treated with suitable form oil or release agent. The form oil

shall be applied so as to provide a thin uniform coating to the forms without

coating the reinforcement.

194 -


19.2.3 Forms shall have sufficient strength to with stand all pressure resulting

from concrete placement and vibration without deflection from the prescribed lines

during and after the placement of concrete and shall be maintained rigidly in

position. Where form vibrators are to be used, it shall be ensured that the form

work is adequately rigid to effectively transmit energy from the form vibrators to

the concrete without damaging or altering the positions of forms. The forms shall

be made sufficiently rigid by use of ties and bracings to prevent any displacement

or sagging. Suitable struts or stiffeners shall be used wherever considered

necessary. The forms shall be made mortar tight. The formwork should comply to

IS 14687.

19.2.4 After the forms for concrete structures have been erected to line and

grade, they shall be meticulously inspected as to their adequacy. If the forms are

not leak proof, there will be a loss of slurry which shall result in honey-combing of

concrete. If the inspection reveals that the forms are not strong enough to hold

the concrete or are not braced sufficiently to stay in alignment, the Engineer-in-

charge shall immediately notify the contractor to set right the deficiencies and

concrete shall not be placed before the forms are re-inspected and found OK.

It shall also be checked during inspection that the form work, as erected, confirms

to the line, grade and alignment. Fully adequate rigidity of forms is of paramount

importance. Use of internal vibrators requires that the forms be tight and strong.

19.2.5 Stability is a very important consideration in the construction of forms.

Every one concerned, including the contractor shall be made to understand that

the common deficiencies resulting in form failure are:

(i) Inadequate cross bracing of shores;

(ii) Inadequate horizontal bracing;

(iii) Failure to regulate the rate of placement of concrete in the forms.

(iv) Poor regulation of the horizontal balance of the form filling;

abnormal form displacements during and after concrete placement; no

provision for lateral pressures; and lack of adequate inspection of form

work;

195 -


In form construction, it is very important that ready access be provided for

proper placement, working, and vibration, and for inspection of these operations.

19.2.6 The surface of form work shall be made such as to produce surface

finishes as specified and the joints shall be tight enough to prevent loss of

liquid/slurry/mortar from concrete. Joints between the form work and the previous

lift shall be grant tight.

19.2.7 Horizontal Construction Joints A very common blemish on formed

concrete surfaces is the off-set often found at horizontal construction joints where

the forms have given way a fraction of couple of centimetre at the bottom of the

new lift. For surfaces where appearance and alignment are of considerable

importance, these off-sets shall be prevented by so setting the forms as to fit

snugly against the top of concrete in the previous lift and then securing them so as

to remain in tight contact during the concrete placing operations. The anchoring

shall be done by using an ample number of ties and bolts, above and within a few

centimetre of the construction joint. The ties in the top of previous lift cannot be

relied on to prevent a slight spreading of the forms at the joint. Forms shall overlap

the hardened concrete in the lift previously placed by not less than 50 cm though

25 cm lap is considered sufficient, however suitable IS may please be referred.

Utmost care shall, thus, be taken by the contractor to ensure that the construction

joints are smooth, free from sharp deviations, projections, or edges.

19.2.8 Spaulling From The Face Of Concrete : Occasionally, spaulling may

occur from the face of the concrete when forms are removed. This is often caused

by rough spots on the forms where mortar adheres strongly enough to over-come

the tensile strength of the green concrete. Such areas on the forms shall be

cleaned, polished, and then covered with suitable form oil. Wire brushing of timber

forms shall be done very carefully to remove the set mortar as else it may

aggregate the situation.

19.2.9 Filling Of Bolt Holes (She-Bolts) Or Holes Of Ties/Rods : The holes left on

the concrete surfaces by she-bolts or rods etc. shall be reamed, cleaned, and

filled with “dry pack mortar” within a reasonable period of the removal of form

work. Such filling shall be made flush with the concrete surface.

196 -


19.2.10 Re-Use Of Forms : The forms required to be used more than once

shall be maintained in a good condition and shall be thoroughly cleaned and

repaired (if required) before reuse. Where metal sheets are used for lining the

forms, the sheets shall be placed and maintained in the forms without lumps or

other imperfections. All forms shall be checked for proper shape, cleanliness, and

strength before re-use.

19.2.11 Inspection Of Forms: The contractor shall inform the Engineer-in-

charge well in time before commencement of placement of concrete in the forms

to enable him or his representative to inspect the formwork as to its adequacy,

suitability, alignment, strength, and overall fitness; and such inspection shall not

relieve the contractor of his sole responsibility for the safety of men, materials,

equipment and the results obtained.

19.2.12 Quality Assurance: Ok Card System shall be introduced. The format

of OK card shall be determined by the Quality Control Organisation and the

contractor or his representative shall be required to fill in the relevant fields of OK

card against all relevant items (as prescribed by the Engineer-in-charge) and sign

to indicate that these are in conformity with specifications. Thereafter the

Engineer, authorized by the Engineer-in-Charge shall inspect these items and any

defects pointed by him shall be duly rectified by him. Broadly, the items shall

comprise of :

Preparation of surface of forms, form oil applications;

Alignment, tolerances;

Stability, bearing and support adequacy, ties, and spacers;

Inspection openings, size, spacing, and locations;

Final clean-up; and

Final OK Card for concrete placement.

197 -


19.2.13 Stripping Of Form Work The Engineer-in-charge shall be

informed in advance by the contractor of his intention to strike/remove any form.

The forms shall not be removed until the concrete has achieved adequate

strength. As per IS: 456-2000, the concrete should have achieved a strength of at-

least twice the stress to which the concrete may be subjected at the time of

removal of form work. While this criteria of strength shall be the guiding factor for

removal of form work, in normal circumstances, where ambient temperature does

not fall below 150C and where ordinary portland cement is used, and adequate

curing is done.

Following striking period of forms be adopted, which shall satisfy the above criteria

of strength of concrete: Ref. IS 456:2000, page No.25, Item No. 11.3

Type of form work Minimum period beforestriking form work.

(a) Vertical form work to columns, walls, beams. 16-24 hours(b) Soffit form work to slabs (props to be refixed

immediately after removal of form work)3 days

(c) Soffit form work to beams (props to be refixedimmediately after removal of form work)

7 days

(d) Props to slabs :(1) Spanning up-to 4.5m. 7 days(2) Spanning over 4.5m. 14 days

(e) Props to beams and arches:(1) Spanning up-to 6.0m. 14 days(2) Spanning over 6.0m. 21 days

For cements other than OPC and lower temperatures, the stripping time

specified above shall be suitably modified by the Engineer-in-charge. The

contractor shall ensure and it is his responsibility that the number of props left

under, their sizes, and disposition shall be such as to be able to safely carry the

full dead load of the slab, beam, or arch, as the case may be, together with any

live load likely to occur during curing or further construction.

Forms shall be removed with care so as to avoid any damage to the

concrete. Concrete damages, if any due to removal of forms, shall be promptly

repaired by the contractor as per method of such repairs prescribed/directed by

the Engineer-in-charge to his entire satisfaction.

The cost of form is included in the concrete item and will not be paid separately.
