5.8.0 MIX VARIATION :

Cement variation in the concrete mix shall not constitute an extra item.

In case the ratio of cement to total aggregate is modified by changing the cement

content under specific orders of the Engineer-in-charge, the .Contractor shall be paid at

increased or reduced rate according to the variation in the cost of cement alone

resulting from change in mix proportion, calculated as per table given below, at the rate

as given in Annex „A‟ of Detailed Tender Notice.

Fine and coarse aggregate shall be measured by dry volumes in suitable wooden boxes.

Overall cement consumption for Individual Items during working season shall be within

(+) or (-) 2%. In case the cement consumption is less than 2% than that specified, the

work shall be paid at reduced rates.

5.9.0 DESIGN MIX :

The ratio of the volumes of the fine and coarse aggregate may be varied within limits of

1 : 1.5 to 1 : 2.5 as directed by the Engineer-in-charge to surt the maximum size of

coarse aggregate, the grading, density, workability and strength without extra cost.

The quantity of water shall be just sufficient, but not more than sufficient to produce a

dense concrete of required workablility for its purpose. An accurate control shall be kept

on the quantity of mixing water. An allowance shall be made for surface moisture persent

in the aggregates when computing water content as indicated in I. S. 456-1978.

Nominal mix propor tions of concrete are given In para 4.8.0. However, the exact

proportions in which the materials are to be used tor different parts of the work shall be

determined by carring out mix design to obtain the specified strength of the concrete.

The design of mix, shall be submitted by the contractor and got a pproved from the

Engineer-in-charge at least one month before the commencement of the work. The

design may be changed at any given time at the discretion of the Engineer-in-charge

during progress of the work. The samples of aggregates and cement and the resuling

concrete, as well as the concrete mix design shall be tested as per relevant I. S.

applicable.

(146)


Sub Dnl Officer






The tests shall be made by the Corporation at frequent intervals as decided by the

Engineer-in-charge. So as to secure the required workability, density, impermeability,

strength and economy.

All the materials going in each batch of concrete shall be weighed before use. The

amount of each individual size of aggregate entering each batch of concrete shall be

determined by direct weighing. The amount of water shall be added after weighing or

volumetric measure. All measuring equipment shall be calibrated correctly and certificate

from the competent authority shall be obtained as and when demanded by the Engineer-

in-charge. All measuring equipments shall be so designed and operated that the

combined inaccuracies In feeding and measuring the materials will not exceed, one and

half percent for water or cement and two and half percent for each size of aggregate.

Any batch of concrete not satisfying this requirement is liable to be rejected. No cement

older than 60 days from the date of despatch from the manufacturer shall be used on the

work. The cement to be used shall be in the Oder of its receipt so that no stock remains

unused for duration longer than 60 days. Cement older than 60 days shall be removed

from site as per the directives of Engineer-in-charge.

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

minimum 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 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 means 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.

(147)


Sub Dnl Officer






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

a) The ingredeint shall be fed into the mixer simultaneosly.

b) A portion of water ( between 5 and 10 percent) shall precede and an equal quantity

shall follow introduction of the other materials. The remainder of the water shall be

added uniformly and simultaneously with the other materials.

c) Care shall be taken that mixing of concrete in the mixer shall be uniform.

5.9.1 CEMENT :

The cement shall be procured as per para 14 of Special Conditions of Contract in

Sub Dnl Officer






5.10.3 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 metre of each

type of concrete laid and atleast three times a day, if out put is more than 75 cubic

metre. The samples 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 the Contractor free of cost and collection of samples, casting of cubes and

testings shall be carried out at the Corporation‟s cost.

5.10.4 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 occasionally accept the crushing strength of a sample which is less

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

strength. Each sample of work test cubes shall assume to represent 30 M3 concrete and

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 occasional cases

2) Equal to or more than 90% but less than 95% 5% reduced rates

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

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

no ticed shall be removed and redone by the contractor at his cost. Unit for acceptance

or these tests will be one working season.

In addition to the 28 days strength tests, the Engineer-in-charge may at his discretion

take 7 days strength tests and/or 3 days (accelerated curing) strength tests and fix up

the relation between such strength and 28 days strength after studying the actual values

realised. If at any time the tests i.e. 7 days or 3 days (accelerated curing) stength

indicate 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 Contractors shall comply there with

without such suspension of work being made a reason for any claim. 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 shall not be accepted as

reason for any claim.

5.10.5 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 Indian

Standard Specification. The allowable slump shall be decided by the Engineer-in-

charge, depending upon the location of the concrete.

5.10.6 In the case of reinforced concrete work, the workability shall be such as the concrete will

surround and properly grip all the reinforcement. Water cement ratio will be such as will

give concrete just sufficiently wet to be placed and compacted without difficulty.

5.10.7 Concrete shall have a consistency such that it will be workable in the required position

and in the case of R. C. C. flow around reinforcing steel also.

5.10.8 For vibrated concrete slump shall range between 2.5 cm. to 5 cm. The slump shall be

the less permitted by workability. The slump shall be determined as detailed in Appendix

„G‟ of I. S. 456-1978 and maintained throughout the concreting operation of a member.

5.11.0 ADMIXTURES :

To improve workability of concrete and cement grout admixtures confirming to IS 9103

could be permitted by the Engineer-in-charge at his discretion, subject to sadtisfactory

and proven use.

5.12.0 FORMS.:

5.12.1 GENERAL:

Forms to confine the concrete and shape it to the required line shall be used wherever

necessary. The form shall have sufficient strength and rigidity to hold concrete and to

withstand the pressure of ramming and vibration without excessive deflection from the

prescribed lines the more so when the concrete is in vibration. The Contractor shall have

to get the design and drawing of the centering approved from the Engineer-in-charge

before erection. Form work shall be of any of the following types.

(150)


Sub Dnl Officer






(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 from warping and is

fabricated true to line and shape. The decision of the Engineer-in-charge as to the

suitablity of wooden shuttering as per (a) above to be used by the Contractor will be

final and binding on the Contractor. The surface of all forms in contact with concrete

shall be clean, rigid, watertight and smooth. Suitable devices shall be used to hold

comers, adjacent ends and edges of pannel of other forms together in accurate

alignment.

5.12.2 DESIGN :

The detailed designs of the form work and false work shall be prepared by the

Contractor and got approved by the Engineer-in-charge well in time. Such an approval

however, will not relieve the Contractor of his responsibility for the adequacy and

strength of the form work and false work.

Forms shall be as designed and constructed as to be removable in sections without

damaging the surface of the concrete and with facilities of removal in ascending order

without disturbing the remaining forms required to be removed later.

5.12.3 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, wormholes 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

hard wood. The dimensions 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 strengthened with framing of angle or

other sections shall be used.

Wooden forms may also be lined within thin steel sheet or plywood to give the required

surface or finish.

5.12.6 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 revated joint or by

caulking or

(151)


Sub Dnl Officer






nailing to the construction operations. The nuts and bolt heads in side the form work

adjoining the concrete should be contersunk. 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. The effect of vibration shall be taken into

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

5.12.5 TREATMENT OF THE INNER SIDES OF FORMS :

Before placing concrete the inner side 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

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

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

coating. All chippings, saw dust and other rubbish shall be removed from the interior of

the forms before concreting.

5.12.6 FALSE WORK :

False work shall be built on foundation or base of sufficient strength to carry the loads

without settlement. False work which can not be found on solid footing must be

supported by piles or other similar devices. False work shall be designed to carry the full

loads including that due to construction operation comming upon it.

5.12.7 ERRECTION AND REMOVAL OF FORMS :

The false work and form work shall be errected with an eye for absolute safety of the

form work and concrete work before and after pouring concrete. Watch should be kept to

see that the behaviour of centering and form is satisfactory during concreting. Erection

should also be such that it would allow removal of forms in proper sequence without

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 for alI

the consequent damages to work, injury to life and damage to property and make good

the damage at his cost.

i) Before placing concrete the surface of forms shall be oiled with a suitable

nonstaining oil such as raw linseed oil so as to prevent sticking of concrete and facilitate

the removal of form.

ii) The oil shall cover the forms fully and evenly without excess over drip. Care shall be

taken to prevent oil from getting on the surface of the construction joints and on

reinforcement bars. Special care shall be taken to oil thoroughly the forms strips for

narrow grooves so as to prevent swelling of the forms and the consequent damage to

concrete prior to or during removal of forms. Immediately before concrete is placed, care

shall be taken to see that all forms are in proper alignment and the supports and fixtures

are thoroughly secured and tightened.

(152)


Sub Dnl Officer






iii) Where forms for continuous surface are placed in successive units, the form shall fit

tightly over the completed surface so as to prevent leakage of mortar from the concrete

and to maintain accurate alignment of the surface.

iv) Forms shall be left in place until their removal is authorised and shall then be

removed with care so as to aviod injury to concrete.

v) Removal of forms shall never be started until the concrete is thoroughly set and

hardened adequately to carry its own weight, beside the live load which is likely to come

on the work during constructions. The length of time for which the forms shall remain in

place shall be decided by the Engineer-in-charge, with reference to weather conditions,

shape position of the structure or structural member and the nature and amount of dead

and live loads.

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

a) Walls, columns and vertical faces of all 24 to 28 hours as may be

structural members decided 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 4.5m 7 days

2) Spanning over 4.5m 14 days

e) Removing of props under beams and arches

1 ) Spanning upto 6m 14 days

2) Spanning over 6m 21 days

Note : The number of props left under 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

acomplished without damaging the concrete surface. No loads will be allowed to damage

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

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

harming the structure or throwing heavy forms upon the floor.

5.12.8 RE-USE OF FORMS 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.

(153)


Sub Dnl Officer






5.12.9 INSPECTION :

The forms and false work will be inspected, checked and approved by the Engineer-in-

charge before concreting commences. But this will not relieve the Contractor of his

responsibility for strength, adequacy and safety of the form and false work.

5.12.10 CONCRETING DURING RAINTS :

When concreting is required to be done or continued while it shall be seen that the

concrete is not damaged due to rain while it is being transported and placed. After

placing the green concrete it shall be adequately covered for a period of 26 hours when

it will be capable for being cured by splash of water. The surface of fresh concrete

should be maintained on a slope sufficient for result in the self drainage of the rain water.

The work shall however be discontinued when the rain is so severs that water collects in

pools or washes the surface of the fresh concrete and it is not possible to provide

adequate shelter.

5.13.0 PLACING CONCRETE :

5.13.1 Concrete shall be placed only in locations where authorised and no concrete or mortar

shall be placed until formwork, Installations of embedded parts, preparation of surface

or necessary clean up has been approved.

5.13.2 ROCK SURFACE :

Rock surface upon or against which concrete is to be placed, shall be prepared as

specified in section of excavation for foundation.

5.13.3 MASONRY SURFACE :

i) Masonry surfaces on which or against which concrete is to be placed, shall be

prepared as described in para 9.2.1 and 9.2.2 of section 9. The unit rate for masonry

shall cover the cost of such preparation.

ii) If the old layer of masonry which has been paid for is required to be removed as

mentioned in para 9.2.2 it shall be back filled with concrete along with upper concrete

layer at no extra cost.

5.13.4 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 week, it shall be prepared not roughened by chipping to a depth of two

centimetres 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 prepartton and

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

for.

(154)


Sub Dnl Officer






5.13.5 ALL SURFACES :

i) The cleaned rock, masonry or concrete surface shall be applied with cement slurry and

then cement mortar coat as described in para 9.2.2 .

ii) The first few batches of concrete may, if as required contain half the regular size of

coarse aggregate without any extra claims.

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

5.13.6 TIME FOR USE :

All concrete shall be placed directly in its final position within thirty minutes of mixing.

Any concrete which has become so stiff that proper placing cannot be assured without

retempering shall be wasted and shall not be paid for. All surface of forms and metal

work including reinforcement bars that have become encrusted with dried mortar of

grout concrete previously placed shall be cleaned of all such mortar or grout before

surrounding or adjacent concrete is placed.

5.13.7 METHOD OF PLACEMENT :

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

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

staff is arranged to deliver 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 delivery 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 continuosly 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 in continuous horizontal layers in a thickness

of approximately 30cm. 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, a 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 the unit rate of concrete

before the entire area to be concreted is covered by previous layers.

5.13.8 RATE OF PLACING :

Concreting should be continued without interruption until the structure or section is

completed or until satisfactory construction joints can be made. Location of construction

joints shall be as directed by the Engineer-in-charge. Concrete shall not be placed, faster

than the placing crew can compact it properly. In placing thin members and columns

(155)


Sub Dnl Officer






precautions shall be taken against too rapid placement which may result in movements

or failure of the forms due to excessive lateral pressure. An interval of at least 12 hours

and preferably 24 hours should elapse between the completion of columns and walls

and the placing of slabs beams or girders supplied by them in order to avoid cracking

due to settlement. All concrete shall be placed in approximately horizontal lifts not

exceeding 1.25 metre in thickness per day. Concrete in arches shall be done in strips

extending from one pier to another. No through joints shall be kept in the span.

5.13.9 CONCRETING AT NIGHT TIME :

If concrete is to be placed at night adequate lightfing arrangements shall be made, as

directed by the Engineer-in-charge.

5.13.10 CONCRETING DURING RAINS :

When concreting is required to be done or continued while it shall be seen that the

concrete is not damaged due to rain while it is being transported and placed. After

placing the green concrete it shall be adequately covered for a period of 24 hours when

it will be capable for being cured by splash of water. The surface of fresh concrete

should be maintaned on a slope sufficient for result in the self drainage of the rain water.

The work shall however be discontinued when the rain is so severe that water collects in

pools or washes the surface of the fresh concrete and it is not possible to provide

adequate shelter.

5.14.0 COMPACTION :

5.14.1 GENERAL :

In all concrete works, required nos. of vibrators, with stand by in working condition will be

kept ready at site as per the instructions of the Engineer-in-charge.

5.14.2 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 express 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 in to 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 and rods to get a good finish without honeycombing. The vibrator

shall however, not revibrate concrete which as commenced its final set. Special care

shall be taken to see 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.

(156)


Sub Dnl Officer






5.14.3 Each layer of concrete, for surfaces which is required to be smooth and for all surfaces

which will be permanently exposed to the weather, and for all surfaces next to embedded

metal work shall be worked and vibrated by mechanical vibrator of approved type only so

as to obtain a concrete of maximum density and Imperviousness and to assure close

contact of the concrete with forms, reinforcement bars and other embeded parts. If the

methods of transporting and placement have been conductive to air entrainment

segregation of stiffening, the work of compaction should receive special attention.

5.14.4 For concrete surfaces exposed to flow of water special precaution shall be taken to

minimise and to prevent surface pitting and protrusions without resorting to over

manipulation of the concrete mix to the forms. No plastering for getting a smooth finish

shall be permitted at these locations. Any protrusion shall be ground smooth.

5.15.0 CURING AND PROTECTION :

All concrete shall be protected against injury until final acceptance. Exposed finished

surface of concrete shall beprotected from the direct rays of sun of atleast 72 hours after

placement. Concrete shall be kept continuously moist for not less than 21 days.

Construction joints shall be cured in the same ways as other concrete and shall also be

kept moist for atieast 72 hours prior to the placing of additional concrete upon the joints.

Approximately horizontal surfaces shall be cured by sprinkling, ponding, or by covering,

or by damp sand or may be cured by the use of wet quilts or mats. Vertical surfaces shall

be cured bycovering with wet jute bags. If damp sand or quilting is used for curing, it

shall be removed completely later. Should the concrete that has become dry or powdery

through neglect of curing the Contractor shall rectify the work at his own extra cost. If

curing arrangements by the Contractor are not satisfactory the Engineer-in-charge may

in his discretion engage labour and provide material and equipment for curing and

recover expenditure thus involved from Contractor.

5.16.0 FINISHING :

5.16.1 GENERAL :

Finishing of formed and unformed surface shall be performed only by skilled workmen.

All exposed concrete surface shall be cleaned of all incrustations of cement mortar or

grout. Unsightly stains shall be removed.

5.16.2 FORMED SURFACES :

Surface of concrete finished againt form shall be smooth, free from projections and filled

thoroughly with mortar. Immediately upon removel forms, all unsightly ridges or fines

shall be removed and any local bulging on exposed surfaces shall be remedied by

tooling and rubbing. All holes left by the removel of fasteners shall, after being reamed

with toothed reamer, neatly filled with dry patching mortar. All porous and fractured

concrete

(157)


Sub Dnl Officer






and surface concrete to which additions are required to bring it to the prescribed lines

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

used for filling the chipped openings and these shall not be less than 8 cm. in depth and

the concrete filling shall be reinforced and dowelled to the surface of the openings.

Honey combed surfaces and surfaces which give a hollow sound shall be rectified by

guniting at the Contractor‟s cost within the unit rate accepted for concrete.

5.16.3 DRY PATCHING :

Dry patching mortar shall consist of one part of cement to 2 parts of sand by volume and

just enough water so that the mortar so used, will stick together on being moulded into a

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

the hands damp. The mortar shall be placed in layers of not more than 2 cm. thickness.

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

effective bond with the succeeding layers. The last or 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

shrinkage cracks.

5.16.4 FINISHING PERMANENTLY EXPOSED SURFACE :

Except as otherwise specified or directed all permanently exposed concrete surface and

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

finished in the following manner, immediately upon the removal of the form the surface

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

cement and fine sand in proporation (1:2) in to the pits with burlap so as to secure a

uniformly 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 materials, they shall

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

mortar filling is placed. Such cleanings shall be done by means of air and water jets

and chipping of brushing or other satisfactory means without damaging the surrounding

concrete. All operations in connection with the filling of surface pits shall be handled as

quickly as practicable to minimise the period during which the concrete and mortar filling

are exposed to the drying. When the treatment of a surface has been completed the

surfaces shall be neat and of the same colour and texture as the adjoining concrete.

5.16.5 FINISHING CONCEALED SURFACE :

For exterior concealed surfaces below ground or back fill level or like surfaces not

otherwise specified, no finish is ncessary except that sandstreaks metal pockets, honey

combing or other imperfections which are of consequence affecting strength, water

tightness or protection of reinforcing steel from corrosion, shall be corrected and repaired

as prescribed for formed surface.

5.16.6 FINISHING UNFORMED SURFACE :

Unformed surface shall be finished by one or more of the operation of screeding floating

and trowelling of the surface should be done at proper time employing experienced men

and should be just sufficient to produce the desired finish. Screeding 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

trowelled a section or final floatings should be performed after some stiffening has

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

finish is desired floatings 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 the

surface. Excessive trowelling particularly at early time shall be avoided.

5.16.7 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 methocts 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

asure 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.

5.16.8 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.

5.17.0 NOMINAL MIX :

The locations indicated in Column No. 6 of the statement below are only suggestive. The

nominal mix used for different components shall be as directed by the Engineer-in

charge according to requirements of detailed design. The Contractor shall not be entitled

6 . POINTING

6.0 SCOPE

The item shall consists of furnishing of all tools, equipment, materials and labour required

to transpor t material and providing pointing to masonr y work including scaffolding and

curing. The pointing shall be flush or pressed jointing as directed by the Engineer-in-

charge.

6.1 PROPORTION OF MORTAR

All pointing shall be done with cement mortar (1:2) unless otherwise specified. The

cement shall be confirmed to the specifications mentioned in section IC-sub-section A The

sand to be used shall be fine. It shall pass through sieve of size No.16 Mesh A.S.T.M.

(IS120). The sand shall confirm in all other respects to specifications under section IC-

sub-section B.

6.2 RAKING JOINTS

The joints in masonry to be pointed shall be raked square for a minimum depth of not less

than the width of joint when the mortar is firm but not set.

6.3 CLEARING JOINTS

Before pointing the joints shall be thoroughly cleaned of any dirt of loosely adhering

cement or mortar and washed out properly and thoroughly wetted.

6.4 FILLING JOINTS

The joints shall then be filled with cement mortar 1:3 unless otherwise specified. Mortar will

be thoroughly rammed and caulked into the joints. The pointing mix shall neither be too

dry nor too wet. The mortar shall have just enough water so that it will stick together on

being moulded into a ball by a slight pressure of the hands but will not free water when so

pressed and will leave the hands damp. Pointing shall be carried out as rapidly as possible

and not touched again after the mortar has once begun to set.

6.5 FLUSH POINTING

The joints shall be filled with cement mortar which shall be thoroughly rammed caulked

into the joints. No lines shall be pressed on the joints but the joints shall instead be nearly

rubbed smooth as soon as the mortar has begun to act. The extra mortar on the edge shall

be carefully scarped off to give a neat appearance. Pointing shall be carried out as

rapidly as possible and not touched again after the mortar has once

begun to set.

(162)


Sub Dnl Officer






6.6 PRESSED POINTING :

The joints shall be pressed with special trowel “ Nayala “ as soon as the mortar has begun

to set and the hollow spaces refilled with fresh mortar to consolidate in. The joints shall be

rubbed with nayala till they are about 5 mm deep into the masonry. After rubbing, the extra

mortar of the edges of joints shall be carefully scrapped off with the nose of the trowel to

give neat finish.

6.7 FINAL FINISH TO JOINTS :

The joints shall be neat defined, regular and of a uniform width. The joints shall be raised

over the surface of the masonry. In coursed masonry, the joints shall be truly horizontal

and vertical. The work pointed should be kept wet for 21 days after pointing is completed.


The item covers all the pointing work required for different classes of masonry. The work

shall be measured and paid at specific rate mentioned by the contractor in the bill of

quantities on square meter basis. The rates are inclusive of all leads & lifts.

7. FORM WORK

GENERAL

1. 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.

2. 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 negated by manual labour in repairs and final dressing of the structure to an

acceptable appearance.

TOLERANCES

3. The form work shall be designed and constructed to the shapes, lines, and

dimensions shown on the drawings within the following tolerances :

A. Linear Outline.

(a) In any 6m of length ± 12mm

(b) In any 12m of length ± 18mm

B. Plumb, specified batter, or from the curved surfaces of all structures including

the lines and surfaces of columns, walls, piers, buttresses etc.

(a) In 3m of height ± 12mm

(b) In 6m of height ± 18mm

(c) In 12m of height or greater ± 30mm

C. Deviations from specified dimensions

of cross-section of columns and beams.

+ 12mm

- 6mm

D. Deviation from dimensions of footings.

(a) Dimensions of plan + 50mm

- 12mm

(b) Eccentricity 0.02 times the width of the footing in the direction

(c)

Thickness

of deviation but not more than 50mm.

± 0.05 times the specified thickness.

Note : These tolerances apply to concrete dimensions only, and specified thickness not to

the positioning of vertical reinforcement steel.

(164)


Sub Dnl Officer






WORKMANSHIP, CLEANLINESS, AND STRENGTH OF FORM WORK.

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.

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.

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 effective 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.

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

tight, there will be a loss of mortar which shall result in honey-combing of

concrete or a loss of water which shall cause sand streaking. 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, conforms to the line,

grade, alignment to the specified tolerance limits. Fully adequate rigidity of

forms is of paramount importance since the tolerance limits specified are for

finished concrete and NOT for the forms. Use of internal vibrators requires that

the forms be tight and strong.

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 :

(165)


Sub Dnl Officer






(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;

(v) abnormal form displacements during and after concrete placement;

(vi) no provision for lateral pressures; and

(vii) lack of adequate inspection of form work;

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

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

operations.

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.

HORIZONTAL CONSTRUCTION JOINTS

7. 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 centimeters 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 centimeters 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 more than about 50mm

though 25mm lap is considered sufficient. Utmost care shall, thus, be taken by

the contractor to ensure that the construction joints are smooth, free from sharp

deviations, projections, or edges.

SPALLING FROM THE FACE OF CONCRETE

8. Occasionally, spalling may occur from the face of the concrete when forms are

removed. This is often caused by rough spots on the forms where mor tar

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 a 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.

FILLING OF BOLT HOLES (SHE-BOLTS) OR HOLES OF TIES/RODS

9. 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.

(166)


Sub Dnl Officer






RE-USE OF FORMS

10. 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.

INSPECTION OF FORMS

11. 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.

QUALITY ASSURANCE

12. Ok Card System shall be introduced. The form-at of ok card shall be

determined by the Engineer-in-charge and the contractor or his representative

shall be required to fill in the first column 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 There after 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 for concrete placement.

STRIPPING OF FORM WORK

13. 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 atleast 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 during is done,

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

criteria of strength of concrete :
