nearest similar item in other schedule of quantity. The opinion of the Engineer-in-Charge

as to whether or not the rate can be reasonably so derived from the item in this contract

will be final and binding on the contractor.

iii) If the altered, additional or substituted work includes any work for which no rate is

specified in the contract for the work and which cannot be derived in the manner specified in

sub para (i) and (ii) from the similar class of work in the contract then such work shall be carried

out at the rates entered in the Schedule of Rates ( as mentioned in “Memorandum to the Form

of Tender” for Civil/ Sanitary Works ) minus/plus the percentage which the tendered amount of

scheduled items bears with the estimated amount of schedule items based on the Schedule of

Rates ( as mentioned in “Memorandum to the Form of Tender” for Civil/ Sanitary Works ). The

scheduled items means the items appearing in the Schedule of Rates (as mentioned in

“Memorandum to the Form of Tender” for Civil/ Sanitary Works) which shall be applicable in this

clause (ii) of Clause 69.1 and the Engineer-in-Charge may revise their rates, having regard to the

prevailing market rate and the contractor shall be paid in accordance with the rates so fixed. The

Engineer-in-Charge shall, however, be at liberty to cancel his order to carry out such increased

quantities of work by giving notice in writing to the contractor and arrange to carry it out in such

manner as he may consider advisable. But, under no circumstances the contractor shall suspend

the work on the plea of non-settlement of rates of item falling under this Clause.

All the provisions of the proceeding paragraph shall equally apply to the decrease in the rates of

items for quantities in excess of the deviation limit, not-with- standing the fact that the rates for

5.1 Material :

The brick work shall consist of the classes of bricks and kinds of mortar, described in the general specifications and indicated in the drawing. Bricks shall conform to CPWD specification and mortar to relevant specification according to the kind of mortar specified.

5.2 Class of Brick Work :

The brick work shall be classified as first class, second class or third class according to the class brick work and 12 mm in third class brick work. These thicknesses apply only in case of traditional bricks. In case of modular bricks, the thickness of joints shall be 1 cm.

5.3 Soaking of Bricks :

First and second class bricks required for masonry in cement or composite cement lime or lime mortars shall be thoroughly soaked in water before use for a minimum period of

six hours.

The contractor shall provide brick lined tanks of sufficient capacity to admit of the simultaneous immersion of one days supply of bricks for the work at its normal rate of progress.

If the bricks are soaked for the required time in water the soluble salts in the bricks may be leached out and subsequent efflorescence may be reduced.

For third class brickwork, the bricks must be only dipped (not soaked) into a tub of water before use. Bricks required for masonry with mud mortar need not be soaked at all.

After the bricks are soaked, they shall be removed from the tank sufficiently in advance

so that at the time of laying they are skin dry. Such soaked bricks shall be earth being smeared on them.

5.4 Laying:

In first class brickwork, selected bricks with best shape and most uniform colour shall be picked out and used for face work. All bricks work shall be constructed in English bond, unless otherwise ordered by the Engineer – in – charge, both in straight walling and in all splays, junctions etc. half or cut bricks shall not be used except where necessary to complete the bond. Closers in such cases shall be cut to the required size and used

near, but not at the end of walls. The bricks shall be laid in mortar to line, level and shapes shown on the plans, slightly pressed and thoroughly bedded in mortar and all joints shall be properly flushed and packed with mortar so that they will be completely filled with mortar and no hollows left anywhere. They should not also be thrown from any height but should be put down gently.

The walls shall be taken up truly plumb. All courses shall be laid truly horizontal and all vertical joints shall be truly vertical. Vertical joints in alternate courses shall come directly one over the other. The thickness of brick courses shall be kept uniform and for this purpose a wooden straight edge with graduations giving thickness of each brick course including joint shall be used. The height of window sills, bottom of lintels and such other important points in the height of wall shall be marked on it. Bricks shall be laid with frog upwards. A set of tools comprising of a wooden straight edge, mason’s spirit level, square, two foot rule, string and plumb shall be kept on the site of work for every 3 masons for frequent checking during the progress of work. When less than 3 masons are employed on a job, one complete set of tools shall be kept. In case of first class brick work with 7 cms. thick bricks the thickness of four courses with four horizontal joints shall be kept as 30.5 cms.

Both the faces of the walls with thickness of more than one brick length shall be kept in

proper plane. All the connected brickwork shall be carried up nearly at one level and no portion shall rise more than 60 cms. above the general construction level, to avoid unequal settlement and also improper joining. Where this is not possible the work shall be raked back according to bond at an angle not exceeding 450.

The courses at the top of the plinth, sills and at the top of the parapet shall be laid with brick on edge (applicable only in the case of traditional bricks), and at corners and dead

ends the bricks shall be properly radiated and keyed into the position by using cut bricks. For half brick partitions to be keyed into the main walls, indents shall be left in the latter.

5.5 Angles and Junctions:

At all angles forming the junction of walls the bricks each wall shall in alternate courses

be carried into the other wall so as to thoroughly unite the work, in accordance with the practice in English bond.

When a brick is omitted to allow for support for a scaffold pole, such brick shall always be header and not more than one header for each pole shall be omitted.

5.6 Finishing of joints:

The face joints shall be raked to a minimum depth of 13mm by raking tools daily during the progress of work, when the mortar is still green, so as to provide proper key for the plaster or pointing to be done. Where plastering or pointing is not required to be done, the joints shall be struck flush and finished at the time of laying. The face of brick shall be cleaned daily and all mortar droppings removed. All iron fixtures, pipes, outlets of water, hold fasts of doors and windows wall etc. which

are required to be built in walls shall be embedded in cement mortar or in cement concrete as specified in their correct position as the work proceeds.

5.7 Curing :

Fresh work shall be protected from rain by suitable covering. Masonry work in cement

or composite mortar shall be kept constantly moist on all faces for a minimum period of 10 days. The top of masonry work shall be left flooded at the close of the day.

No curing shall be done in the case of masonry with mud mortar while in case of fat lime mortar, curing shall commence two days after laying of masonry and shall continue for 10 days.

5.8 Scaffolding :

For important brickwork, double scaffolding having two sets of vertical supports shall be provided. The supports shall be tied together with horizontal pieces over which the scaffolding planks shall be fixed. For ordinary buildings single scaffolding shall be allowed. The holes left in the masonry work for supporting the scaffolding shall be filed

and made good.

Dimensions shall be measured and quantity of individual items worked out correct to two places of decimals of metre and a cubic metre respectively.

No deductions shall be made for ends of dissimilar materials like girders, beams, lintels, rafters etc. upto 500 sq.cms. in section, and for opening upto 0.1 sqm. in face area.

When the brickwork is to be plastered measurements will be exclusive of plaster. Width of walls shall be measured actually in multiples of half bricks, which shall be deemed to be inclusive of the mortar joints, but limited to the width specified on the drawings. Any increase in thickness of walls due to thicker mortar joints or oversized bricks shall not be

paid for.

Where fraction of half bricks occurs due to architectural or other requirements, the measurements shall be taken actual.

6.0 SPECIFICATION FOR CEMENT PLASTER

6.1 Mortar:

The mortar of the specified mix shall be used and shall be prepared in accordance with C.P.W.D detailed specification.

6.2 Cleanliness:

Adequate protection shall be given to all existing work and fittings which are liable to be damaged, not only in the area of plastering operations, but also in the approaches there to-by covering up with boards, dust sheets etc. as necessary.

6.3 General:

For external plaster, the plastering operations should be started from the top floor and carried down wards. For internal plaster, the plastering operations may be started

wherever the building frame is ready and centering of the roof slabs have been removed. Ceiling plaster shall be completed 2 or 3 days in advance of the wall plaster. in the case of ceilings of roof slabs, plaster shall not be commenced until the terrace work has been completed so that the ceiling plaster is not disturbed by the vibration set up in the above operation.

6.4 Scaffolding:

As per details specification for brickwork.

7.0 PREPARATION OF BACK GROUND FOR APPLICATION OF PLASTER:

The joins of the masonry shall be racked to a depth of 18 mm for providing key to the plaster. The loose layer of dust and mortar on masonry shall be brushed away before

the plaster is applied. A stiff bristle brush or wire brush may be used to be more effective.

The surface shall then be sprinkled with water and damped evenly but not soaked with water and kept as such for two days before plastering. If the surface becomes dry in spots, such areas shall be moistened again to ensure uniform bond.

Plaster work, whenever possible shall be done on the shady side of the building, as it is difficult to keep freshly plastered walls adequately damp while being exposed to the sun.

7.1 Application of Plaster:

The plaster over brickwork shall at least be 10 mm thick applied in two or three coats of equal thickness as ordered by the Engineer-in-charge.

All scaffold holes shall be properly filled in advance of the plastering and as the scaffolding is being taken down. To ensure even thickness and a true surface, small patches of plaster 15 cm x 15 cm shall be first applied horizontally and vertically at not more than 2 meters interval over the entire surface to serve as gauges.

The surface of these gauged areas shall be truly in the plane of the finished plaster surface. The mortar shall then be applied on the wall between the gauge in a uniform surface, slightly more than the specified thickness and shall then be brought to a true and even surface by a working a wooden straightedge reaching across the gauges.

7.2 Finishing:

Finally surface shall be finished true with a trawl or with wooden flat according as a smooth surface or sandy granular texture is required.

No steel trowels shall be used for finishing the surface excessive trawling or overworking the float shall be avoided.

The work shall be tested frequently as the work proceeds with a true straight edge not

less than 2.5 meters long and with plumb bobs. All horizontal lines and surface shall be tested with a level and all jambs and corners with a plumb bob. Plastering of cornices, decorative features etc. shall normally be complete before finishing coat is applied.

All corners, angles and junctions shall be truly vertical or horizontal as the case may be and shall be carefully finished. No rounding or chamfering on corners shall be done.

Wherever there is break of continuity, the two portions of the plaster shall be separated by a neat cut through the plaster at the junction.

In suspending work at the end of the day, the plaster shall be left, cut clean to line both vertically and horizontally. When recommending the plaster, the edge of the old work shall be scraped cleaned and wetted with cement slurry, before plaster is applied to the adjacent areas, to enable the two to join together. Plastering work shall be closed at the

end of the day on the body of the wall and not nearer than 15 cm. to any corner. It shall not be closed on the body of such features as bends or cornices. Horizontal joints shall not also occur in parapet tops and coping as these invariably lead to leakages. No portion of the surface shall be left out initially to be patched up later on.

7.3 Thickness:

The thickness of the plaster specified shall be measured exclusive of the thickness of grooves open joints in brick work.

7.4 Curing:

Curing shall be started as soon as the plaster has hardened sufficiently not to be damaged when watered. The plaster shall b kept wet for a period of atleast 10 days.

During this period it shall be suitably protected from sun, rain and frost, at the contractor’s expense and by such means as the Engineer – in – charge may approve. Ordinarily to protect the plaster from sun, the whole surface shall be covered with wet gunny begs. The dates of plaster shall be legibly marked on the various sections of the wall so that curing for the specified period thereafter can be watched.

7.5 Defective Plaster:

Any crack, which appears in the plaster, or any part which sounds hollow when tapped or is found to be soft or otherwise defective, shall be cut out in rectangular shape and replastered at the contractor’s expense.

7.6 Mouldings:

All mouldings shall be worked true to drawings with a properly constructed template and draw neat, clean and straight.

7.7 Measurments:

Plaster shall be measured in length and height of walls, no deductions being made for small size openings such as ordinary doors, windows and ventilators etc. on one face of the wall when both faces are plastered, but in case of plaster on inside and pointing on

the outside, no deduction will be made for plaster work while the entire area of the openings will be deducted from pointing work.

In case of large size openings, such as verandah opening, the area of the openings will be deducted and the actual plaster done on the pillars and soffits shall be measured.

Welding of reinforcement shall be done in accordance with the recommendations of IS 2751-1966 code of practice for welding of bars used for reinforced concrete construction. The reinforcement for the concrete shall be provided perfectly in accordance with the drawing and should be free from twisted and kinds.

The binding of reinforcement will be done with 16 B.W.G.I. binding wire or suitably tack welded. Cages may be manufactured above ground, checked in all respect and lowered and placed in position in trenches provided no deformation or dislocation occurs in the process of lowering.

Preparation of bars & general precautions for welding:

a) Untwisted ends, if any, at weld junctions should be cut (10-15) and removed prior to welding.

b) Bars should be free of rust at the joints to be welded. c) Slag produced in welding after alternate run should be shipped and removed by brush.

d) Electrode should not be lighted by touching the hot bar in order to avoid notch effect.

After every alternate run, the bar is allowed to col before further weld is deposited. Continuous welding can be achieved if about ten joints are set up side by side. In such case, about two runs are deposited in all joints in sequence before further deposit of weld in the first joint is done. This gives the required pause to cool the bar.

9.4 Measurements and payments:

Before starting concerting, the contractor shall make certain that measurements of the reinforcement placed have been recorded and the Engineer – in – charge has certified to the correctness of the reinforcement used. Failure to do so might mean no payment or payment at the unquestioned discretion of the Engineer-in-charge for the reinforcement concerned.

All excavation shall be neatly cut to lines, curves, and slopes and grades shown in the

drawings or as directed by the Employer with plus or minus tolerance of 25mm. Where

excavations are made in excess of the limits delineated on the drawings, either by error or

accident, the extra excavation shall be made good at contractor's cost by refilling to the

proper grade with thoroughly compacted suitable fill or by 1:4:8 P.C.C where it is meant for

foundations.

In excavation for foundations, a bottom layer of 150mm in thickness shall be left undisturbed

and subsequently removed only when the concrete is about to be placed in order that

softening or deterioration of the surface on the bottom of the excavation area by exposure

may be avoided.

The contractor shall make allowances for the working space required to carry out the subsequent construction portion where the excavation is carried out in reusable material.

The materials recovered may be stacked nearby for back filling purposes, as directed by the Employer. All excavation work shall be properly protected against subsidence, slip or caving

in to avoid injury to workmen. The contractor may with the approval of the Employer, carry-

out excavation without any side protection, i.e. with sides of the excavation formed by the natural slope of the earth instead of using timber shoring etc. In this case, the payments will

be made only for the net quantities of excavation required for carrying out the construction work.

The contractor shall at his own cost provide, maintain and operate pumping equipment of

required capacity and keep the area of construction free of water during concreting.

Pumping shall be controlled and necessary care to dispose of the water through drainage,

ditches without causing any inconvenience to construction operation shall be made.

All water from any source whatsoever getting accumulated in excavated areas, trenches,

etc. shall be properly diverted in approved manner or bailed out or pumped by the contractor

at his own cost so that the areas and trenches are kept free of water.

The material obtained from excavation which is not considered suitable for filling operations

shall be disposed off at a place and in a manner as indicated by the Employer.

The surplus suitable material obtained from excavation shall be used for back filling and for

filling as directed by the Employer. Filling shall be evenly laid in layers not exceeding 230mm in thickness. Each such layer shall be consolidated with sufficient watering and tamping. Each layer shall be watered to the optimum moisture content to achieve a density of 95%.

Whenever required, the contractor shall demonstrate adequately at his own cost, by field and laboratory tests that the specified density has been obtained. The contractor shall make well all settlements of filling that may occur up to the end of defect liability period at his expense.

The contractor, if so directed by the Employer shall remove the excavated material from the place of construction to a storage / disposal area and bring back part / full for back filling or for other filling.

BATCHING EQUIPMENT

At the batching plant, standard certified test weights shall be provided and such other auxiliary equipment as may be necessary to check the operating performance of each scale or other measuring device. When required by the Employer, these tests shall be made in his presence. Unless otherwise required by the Employer, check tests of equipment used for measuring water, cement aggregates and admixtures shall be made at least every week. After completion of each check test, contractor shall report the results to the Employer and make such adjustment, repairs or replacement as the Employer deems necessary to secure satisfactory performance before further use of the measuring devices.

Each measuring indicator and volume-measuring device shall be in full view of the operator, and the measuring equipment shall be arranged so that the operator may conveniently observe the operation of the bin gates, the materials discharging into the mixer and the concrete during mixing and discharging. The batch panel shall be equipped with chatter controls to control the dribble for each material batched and a

volume selector capable of settings from 0.5 m3 up to the mixer capacity in increments

of 0.5 m3.

The batching equipment shall be so constructed and arranged that the sequence and timing of the batcher discharge gates can be controlled to produce an intermixing of the aggregate, water and cementing materials, as the materials pass through the charging hopper into the mixer. The batching controls shall be so interlocked that a new batching cycle cannot be started until all the weighing hoppers are completely empty.

The operating mechanism in the water-measuring device shall be such that no leakage will occur when the valves are closed and the discharge valve cannot be opened until the filling valve is closed.

The device for adding admixtures shall be interlocked with the batching and discharging operation of the water so that the batching and discharging of the admixtures will be automatic. The device shall be capable of permitting the quantity of admixture being batched to be adjusted should this prove necessary, and shall be equipped with a suitable warning device to indicate when the level in the reservoir tank is low.

A calibrated container shall be incorporated in each admixture holding system such that normally the admixture will bypass the container during batching. However, at any time it will be possible to direct the batched material into the container to check the accuracy of measurement.

The batching equipment shall include an accurate recorder for providing a continuous visible record of the measurement of each separate material, including all added water and admixture.

The measuring and recording equipment shall be supported on foundations independent of those for the mixing plant to prevent them from being affected by vibration.

Volume batching will not be permitted. In case of use of fully automated batching plant, all the recording and indicating system

intentioned above shall be available and on-line control of all components of the

batching plant shall be provided.

materials, water and other ingredients, within the time hereinafter specified, into a thoroughly mixed and uniform mass, and of discharging the mixture without segregation.

The mixers shall be so charged that some water will enter in advance of cement and aggregate and all materials shall continue to flow in as rapidly as possible. The construction of the mixers should prevent loss of materials during charging.

The mixers shall not be charged beyond their rated capacities and the entire contents of the mixer shall be discharged before recharging.

Unless otherwise authorised by the Employer for mixers of 1m3 capacity or less, the

mixing of each batch shall continue for not less than 1.5 minutes as specified in IS:456 (but not more than 5 minutes when mixing air-entrained concrete) after all materials, except the full amount of water, are in the mixer. For mixers of larger capacity, the minimum mixing time will be increased by 15 seconds for each additional 5 m3.

The mixing time shall be increased when, in the opinion of the Employer, the charging and mixing operations fail to result in the required uniformity of composition and consistency within the batch and from batch to batch.

Mixers shall be rotated at the rate recommended by the manufacturer of the mixers. The arrangement for controlling, measuring and mixing operations shall be such that the

operator may observe the concrete discharging from the mixer. Each mixer shall be equipped with a mechanically or electrically operated timing and

signalling device for indicating and assuring the completion of the required mixing period and for counting the batches.

Should a mixer at any time prove unsatisfactory, it shall be replaced or its use discontinued until it is made satisfactory.

Each mixer shall be cleaned after each period of continuous operation and shall be maintained in such a condition that the mixing action will not be impaired.

Where the distance between the batching plant and a concrete pour is such that it would be in the opinion of the Employer cause deterioration of mixed concrete in transit, any batching may be permitted using transit mix trucks in accordance with IS: Water shall be added not later than 30 min after batching.

On no account shall any addition be made to any component of a concrete batched once that batch has been mixed and discharged from the mixer, whether for the purpose of remembering or for any other reason.

Batching and mixing of concrete shall not commence unless due notice, at least 24

hours in advance, has been given to the Employer and written approval has been

obtained for the placing arrangements, and for the preparation and accuracy of the part

of the Works in which concrete is to be placed.

(10%) extra cement shall have to be added to the normal mixes when mixed by hand. It shall

be carried out on a water tight platform and care shall be taken to ensure that mixing is

continued until the mass is uniform in colour and consistency. No extra payment shall be


TENDER DOCUMENT

made to the contractor for mixing by hand or for using extra cement due to hand mixing. However, cement consumed extra shall be considered for reconciliation purposes.

PLACING AND COMPACTION

Concrete shall be carefully placed in designated position. Where dense reinforcement or deep forms may cause segregation of concrete while placing, suitable methods shall be used to prevent segregation. The free fall of concrete shall not exceed 1.5 m.

Concrete shall be placed directly in its permanent position and shall not be worked along the forms to that position. Vibrators shall not be used to move concrete laterally.

The addition of water into concrete after batching to compensate for stiffening of the concrete before placing shall not be permitted.

The Employer reserves the right to order a reduced thickness of layers where the layers as stated above cannot be placed in accordance with the requirements of these Specifications.

Time interval between successive lifts of mass concrete shall be determined by the Employer. Nevertheless a minimum of 72 hours shall elapse between successive lifts.

No concrete shall be placed under water except where shown on the Construction Drawings or specifically so required by the Employer. No concrete shall be placed in running water. Water shall not be allowed to rise over freshly poured concrete until final set has been achieved.

Each layer of concrete shall be consolidated to the maximum practicable density, be free from pockets of coarse aggregate, completely fill all recesses in forms and around embedded parts, and be free of all voids. The concrete shall be compacted and worked into all corners and angles of the forms, around reinforcement and embedded items without permitting the component concrete materials to segregate.

No layer of concrete shall be placed until the previous layer in the same lift has been thoroughly consolidated. Each layer of concrete within a lift shall be covered with fresh concrete as soon as possible, but certainly within the period when the lower layer is still capable of being re-vibrated so that successive layers can be thoroughly worked together.

The maximum permissible time between the placing successive layers in a pour shall not exceed initial setting time of cement or 45 minutes, whichever is less, and shall be reduced to suit the temperature, humidity and job conditions. Concrete shall not be piled up in the forms in a manner that causes movement of the unconsolidated concrete, or permits mortar to escape from the coarse aggregate.

Concreting of slab shall be carried out by concrete pump using methods which do not cause segregation or requiring remixing of the concrete.

Concrete shall be consolidated with the aid of approved immersion/needle type mechanical vibrators complying with IS:2505. Vibrators with flexible operating shafts shall be used for reinforced concrete and for concrete in restricted forms. At least one extra vibrator in working condition shall be constantly on hand at each point of placement for emergency use.

Application of the vibrators shall be made systematically and at such intervals that the zones of influence overlap and the concrete is properly compacted.

Contractor shall use any or all of the above methods of consolidation, if required, to

produce the necessary finish. Form vibrators shall not be used unless the forms are

designed for form vibration and unless specifically authorised by the Employer.

PUMPING CONCRETE

Positive displacement pumping or other approved methods may be used to place

concrete in locations approved by the Employer. The type and arrangement of

equipment shall be subject to approval, and the equipment shall be operated only by

experienced persons. Pneumatic placing will not be allowed.

Use of aluminium pipe for pumplines shall not be permitted. Couplings shall be leakproof and strong enough to withstand handling during erection and poor support along the lines. They shall provide a full internal cross section with no constrictions of the smooth flow of concrete.

Concrete pumping operations shall be planned in such a way that concrete does not set

before the succeeding layer is place thereon. An adequate supply of fresh concrete

shall be provided at all times.

ITEMS EMBEDDED IN CONCRETE

Concreting shall not be started unless the electrical conduits or any other piping wherever

required, are laid by the concerned agency.

CUTTING

Concrete shall be placed so as to avoid segregation of the materials and the displacement of

the reinforcement and embedment. The use of long troughs, chutes and pipes for conveying concrete from the mixer to the forms shall be permitted only on written authorization from the Employer. In case an inferior quality of concrete is produced by the use of such conveyors, the Employer may order discontinuance of their use and the substitution of a satisfactory method of placing. Open troughs and chutes shall be equipped with baffles or be in short lengths that reverse the directions of movement. All chutes, troughs and pipes shall be kept clean and free from coatings of hardened concrete by thoroughly flushing them with water

after each run, water used for flushing shall be discharged clear of the structure. Concrete shall not be permitted to fall freely from a height of more than 1.5m nor to strike the forms at an angle. Where drop chutes are used, a sufficient number must be provided so that the concrete discharged from the chute is not required to flow laterally more than 1.0m. Where a drop chute is swung from the vertical, the bottom two sections must be maintained in a vertical position to avoid segregation.

BONDING MORTAR

Immediately before concrete placement, the areas of prepared rock surfaces or previously

placed concrete which will be in contact with the concrete to be placed shall be covered with

a bonding mortar or grout. The bonding medium shall have the same cement-sand content

as the concrete which will be placed on it. The water- cement ratio shall be determined by

conditions of place to be concreted and as approved by the Employer.

AVOIDING SEGREGATION

Concrete placed by barrows, buggies cars, short chutes or hand shovelling in restricted

forms shall be subjected to the requirement for vertical delivery of limited height to avoid

segregation. Concrete shall be deposited as nearly as practicable in its final position to avoid

segregation due to re- handling of flowing. For the locations where direct placement is not

possible and in narrow forms, suitable drop chutes and "elephant trunks" shall be provided to

confine the concrete in movement.

THICKNESS OF LAYERS


TENDER DOCUMENT

Concrete shall be placed in successive horizontal layers ranging in thickness not exceeding

500 mm or as directed by the Employer. The bucket loads, or other units of deposit, shall be

spotted progressively along the face of the layer with such overlap as will facilitate spreading

the layer of uniform depth and texture with a minimum of hand shovelling. Any tendency to

segregation shall be corrected by shovelling stones into mortar rather than mortar on the

stones. Such a condition shall be corrected by redesign of mix, change in process or other

means, as directed by Employer.

Bedding planes shall be approximately horizontal.

Each layer of concrete shall be thoroughly compacted and fully worked around the

reinforcement, around embedded fixtures and into corners of the form work with suitable

type of equipment until the concrete has been consolidated to the maximum practicable

density.

CONSTRUCTION EXPANSION JOINTS

When the work is to be interrupted, horizontal and vertical construction joints and bonding

keys shall be located and shall conform in detail to the requirements on the plans unless

otherwise directed by the Employer. Construction joints shall be provided in position as

shown or described on the drawings. Where it is not described, the joints shall be in

accordance with the following.

In a column, the joint shall be formed about 75 mm below the lowest soffit of the beams

framing into it. Concrete in a beam shall be placed throughout, without a joint but if the provision of a joint is unavoidable, the joint shall be vertical and at the middle of the span.

Before fresh concrete is placed, the cement skin or any looser or porous material of partially hardened concrete shall be thoroughly removed and cut back until the solid face is exposed and surface made rough by hacking or any other method as directed by the Employer. The

rough surface shall be thoroughly wetted for about two hours and shall be dried and coated with 1: 1 freshly mixed cement sand slurry immediately before placing the new concrete. Special care shall be taken to see that the first layer of concrete placed after a construction

joint is thoroughly rammed against the existing layer, before the slurry sets.

TREATMENT OF SUSPENSION OF WORK

When the work has to be resumed on a surface which has hardened, such surface shall be

roughened. It shall then be swept clean and then thoroughly wetted. For vertical joints, neat

cement slurry shall be applied on the surface before it is dry. For horizontal joints the surface

shall be covered with a layer of mortar about 10 to 15 mm thick composed of cement and

sand in the same ratio as the cement and sand in concrete mix. Mixed and applied

immediately before placing the concrete.

Where the concrete has not fully hardened, all laitance shall be removed by scrubbing the

wet surface with wire or bristle brushes, care being taken to avoid dislodgment of particles of

aggregate. The surface shall be thoroughly wetted and all free water removed. The surface

shall then be coated with neat cement slurry. On this surface, a layer of concrete not

exceeding 150 mm in thickness shall first be placed and shall be well rammed against old work, particular attention being paid to corners and close spots, work thereafter shall

proceed in the normal way.

SEPARATION JOINT


TENDER DOCUMENT

Separation joint shall be obtained by using a tough alkathene sheet 1 mm thick or equivalent

as approved by the Employer stuck on the surface against which concrete will be placed.

Adequate care shall be taken to cause no damage to the sheet.

EXPANSION JOINTS.

Permanent expansion joints in structures shall be formed in the positions and to the shapes

shown in the relevant drawings. When joints are to be filled with joint filling material as

stipulated in the drawings, the permanently exposed, edges of joints shall be sealed with an

approved sealing compound.

WATER STOPS

The water stops shall be located and embedded at construction / expansion / construction

joints as indicated in drawing and as per manufacturer's recommendations.

Water stops shall be accurately cut, fitted and integrally joined at sectional joints and angular

junctions to provide continuous, watertight diaphragm at all points as per manufacturer's

specifications.

Adequate provisions shall be made for the support and protection of water stops during the

progress of the work.

CURING

Curing of concrete shall be in accordance with IS: 456. Concrete shall be cured by keeping it

moist for the period of time specified herein to ensure that complete hydration and hardening

takes place.

All concrete shall be cured by use of water which shall be continuously (not periodically)

maintained on all exposed surfaces.

Curing shall be assured by use of an ample water supply under pressure in pipes, with all

necessary appliances of hose, sprinklers and spraying devices. Continuous fine-mist

spraying or sprinkling shall be used, unless otherwise specified or approved by the

Employer.

Wherever, in the judgment of the Employer it may be necessary, the continuous spray

method may be omitted and a covering of sand or other approved material such as jute

bag/burlap which will hold moisture for long periods and prevent loss of moisture from the

concrete shall be used. Type of covering which would stain disfigure or damage the concrete

during and after the curing period shall not be approved. Approved covering shall be kept

continuously wet during the specified curing period.

Concrete shall be maintained in moist condition for at least the first seven days after placing

except that high early strength concrete shall be so maintained for at least the first three

days. Other curing period may be used with the permission of the Employer, if the specified

strengths are obtained.

For curing of concrete in pavements, side walls, floors, flat roofs or other level surfaces the

ponding method of curing shall be adopted. The ponded areas shall be kept continuously

filled with water and leaks shall be promptly repaired.


TENDER DOCUMENT

COMMENCEMENT OF CURING

Curing of concrete shall start after 8 hours of placement and in hot weather within 4 hours of

placement for exposed faces. During the first 24 hours, the concrete shall be cured by use of

wet burlap or such other means to cover the concrete surfaces. In very hot weather,

precaution shall be taken to see that the temperature of wet concrete does not exceed 38

deg. Celsius while placing.

Concrete placed below the ground level shall be protected from falling earth during and after placing, surface shall be kept free from contact with such ground or with water draining from

such ground during placing of concrete for a period of at least 3 days unless otherwise directed by the Employer. The ground water around newly poured concrete shall be kept to

an approved level by pumping or other approved means of drainage and adequate steps

shall be taken to prevent floatation and flooding. Steps shall be taken to protect immature concrete from damage by debris, loading, vibration, abrasion, mixing with deleterious

materials that may in the opinion of the Employer impair the strength and / or durability of the concrete.

Approved curing compounds may be used in lieu of moist curing with the permission of

Employer. Such compounds shall be applied to all exposed surfaces of the concrete as soon

as possible after the concrete has set.

TESTING

SLUMP TEST OF CONCRETE

At least one slump test shall be made for every compressive strength test carried out. More

frequent test shall be made if there is a distinct change in work conditions or if required by

the Employer.

STRENGTH TEST OF CONCRETE

Samples from fresh concrete shall be taken as per IS: 1199 and cubes shall be made, cured and tested at 28 days in accordance with IS: 516.

In order to get a relatively quicker idea of the quality of concrete, optional tests on beams for modulus of rupture at 72 + 2 hours or at 7 days or compressive strength tests at 7 days may

be carried out in addition to 28 days compressive strength tests. For this, purpose, the values given in Table- 4 may be taken for general guidance in the case of concrete made with ordinary port land cement. In all cases, the 28 days compressive strength specified in

Table-1 shall alone be the criterion for acceptance or rejection of the concrete. If, however, from tests carried out in a particular work over a reasonably long period, it has been established to the satisfaction of the Employer that a suitable ratio between 28 days

compressive strength and the modulus of rupture at 72 + 2 hours of compressive strength at 7 days may be accepted, the Employer may suitably relax the frequency of 28 days

compressive strength values in table below provided the expected strength values at the specified early age are consistently met. SPECIFICATION: PART A (CIVIL)

PROCEDURE

A random sampling procedure shall be adopted to ensure that each concrete batch shall

have a reasonable chance of being tested, i.e. the sampling should be spread over the entire

period of concreting and cover all mixing units.

Estimated standard deviations = Deviation of the individual test strength from the average

strength of n samples.

Where N = Number of sample test results.

When significant changes are made in the production of concrete batches (for example,

changes in the materials used, mix design, equipment or technical control), the standard

deviation value shall be separately calculated for such batches of concrete.

Assumed standard deviation - Where sufficient test results for a particular grade of concrete

are not available, the value of standard deviation given in Table-5 may be assumed:

M30 60

M35 63

However, when adequate past records for a similar grade exist and justify to the designer a

value of the standard deviation different from that shown in Table-5, it shall be permissible to

use that value.

ACCEPTANCE CRITERIA

Concrete Components The measured values shall be within the specified range of values indicated above. Any unsuitable material should be eliminated and the concrete manufacturing be

suspended until the Contractor justifies that the replacing component is acceptable. Fresh Concrete Any controlled batch which will not satisfy the specified conditions in terms of consistency,

air content and temperature, will be eliminated and concreting suspended until it is shown

that corrections brought to the following batches are satisfactory.


TENDER DOCUMENT

Hardened Concrete The acceptance criteria for hardened concrete shall be as per clause 15 of IS:456. If analysis of test cube results indicates poorer concrete in the structure as per the

acceptance criteria of clause 15 of IS: 456, the Engineer-in-Charge will order the Contractor to provide core tests. Location and number of cores will be decided by the Engineer-in-Charge. The Contractor shall take out the specified sizes of cores from the structure.

In case the concrete cores fail to meet the specifications and the Engineer-in-Charge is

not satisfied with various tests results and quality, he will then instruct the Contractor

for removal or subsequent suitable strengthening measures for such works.

INSPECTION

Immediately after stripping the form work, all concrete shall be carefully inspected and any defective work or small defects, the same shall be removed or made good before concrete is hardened. In case of doubt regarding the grade of concrete used either due to poor workmanship or

based on results of cube strength tests, compressive strength tests of concrete on the basis

of core test and / or load test may be carried out.

CORE TEST

The points from which cores are to be taken and the number of cores required shall be at the

discretion of the Employer and shall be representative of the whole of concrete concerned.

Cores shall be prepared and tested as described in IS: 516.

Concrete in the member represented by a core test shall be considered acceptable if the

average equivalent cube strength of the cores is equal to at least 85 percent of the cube

strength of the grade of concrete specified for the corresponding age and no individual core

has strength less than 75 percent.

In case the core test results do not satisfy the requirements of above para or where such

tests have not been done, load test may be resorted to.

FAILURE TO MEET STRENGTH REQUIREMENT

In the event that concrete tested in accordance with the requirements of this specification

fails to meet the requirement, the Employer shall have the right to require anyone or all of the

following; which shall be carried out by the contractor at his own expense.

Curing and load testing of the concrete member concerned represented by the tests which

failed. The method and manner of load test shall be as under load test mentioned below.

Replacement of any such portions of the structure. No payment for the dismantled concrete,

relevant form work and reinforcements shall be made. Embedded fixtures and reinforcement

or adjoining structures damaged during dismantling shall be made good by the contractor at

his own expense.

LOAD TEST ON PARTS OF STRUCTURES

The Employer may instruct for a load test to be carried out on any structure if in his opinion

such a test is deemed necessary.

If the results of the load test be unsatisfactory, the Employer may instruct the contractor to

demolish and reconstruct the structure or part thereof at the contractor's cost. SPECIFICATION: PART A (CIVIL)

TENDER DOCUMENT

THE LOAD TEST OF STRUCTURES SHALL BE CARRIED OUT AS GIVEN BELOW:

Load tests shall be carried out as soon as possible after expiry of 28 days from the time of placing of concrete. The structure shall be subjected to a load equal to full dead load of the structure plus 1.25 times the imposed load for a period of 24 hours and then the imposed load shall be removed. The deflection due to imposed load only shall be recorded. If within 24 hours of removal of

the imposed load, the structure does not recover at least 75 percent of the deflection under

super imposed load, the test may be repeated after a lapse of 72 hours. Structures shall be

deemed to be unacceptable.

If the maximum deflection in mm, shown during 24 hours under load is less than 40 x L21D, where L Is the effective span in M and D the overall depth of the section in mm, it Isn’t necessary for the recovery to be measured and the recovery provisions given above will not apply. Other non-destructive test methods may be adopted, in which case the acceptance criteria

shall be agreed upon between the Employer and the contractor and the tests shall be done

under expert guidance.

FINISHING CONCRETE

On striking the form work, all blowholes and honey combing observed shall be brought to the

notice of the Employer. The Employer may, at his discretion allow such honey-combing or

blow holes to be rectified by necessary chipping and packing or grouting with concrete or

cement mortar. If mortar is used, it shall be 1:3 mix or as specified by the Employer. However, if honey-combing or blow holes are of such extent as being undesirable, the

Employer may reject the work totally and his decision shall be binding. No extra payment

shall be made for rectifying these defects. All burrs and uneven faces shall be rubbed

smooth with the help of carborundum stone.

The surface of non- shuttered faces shall be smoothened with a wooden float to give a finish

equal to that of the rubbed down shuttered faces. Concealed concrete faces shall be left as

from the shuttering except that honey-combed surface shall be made good as detailed

above. The top faces of slabs not intended to be surfaced shall be levelled and floated to a

smooth finish at the levels or falls shown on the drawings or elsewhere. The floating shall not

be executed to the extent of bringing excess fine materials to the surface.

The top faces of slabs intended to be covered with screed, granolithic or similar faces shall

be left with a rough finish.

REPAIR AND REPLACEMENT OF UNSATISFACTORY CONCRETE

Concrete which is unsatisfactory shall be repaired by cutting out the unsatisfactory material

and by replacing it with new concrete. Voids to be so filled shall be provided with anchors,

keys or dovetail slots wherever necessary to attach the new material securely in place.

Surface of prepared voids shall be wetted for 24 hours immediately before the patching material is placed. Repair of concrete shall be made by skilled workmen. Repairs shall be

made as soon as practicable after removal of the forms and in a manner to meet the

requirements for the finish specified for the particular location.

The use of an epoxy for bonding fresh concrete used for repairs will be permitted on written

approval of the Employer. Epoxies shall be applied in strict accordance with the instructions

of the manufacturer.


TENDER DOCUMENT

METHOD OF REPAIR

"Dry-pack" filling shall be used for small size holes having surface dimension nearly equal to the depth of the hole, for holes left after removal of form ties, grout insert holes and slots cut for repair of cracks. Mortar filling by cement gun shall be used for repair of areas and holes

too large for dry-pack and too shallow for concrete filling. For holes extending entirely through the concrete section, for areas greater than 0.1 sq m. and deeper than100 mm and holes in reinforced concrete which are greater in area than 0.05 sq m. and which extend

beyond the reinforcement, the repair shall be made by making a complete filling of the void with broken stone and liquid port land cement. Grout shall be placed through filler pipes

under pressure. Pipe nipples shall be placed through the forms at bottom of the void so that the grout rises upward through the aggregate to spill through a vent at the top edge of the void.

MATCHING OF PATCH SURFACE

Filling material used in repair of surfaces which will be exposed after completion of the

project shall be made with cement from the same source as that used in concrete and

blended with a sufficient amount of white Portland cement to produce the same colour as in

the adjoining concrete. Patched surfaces shall be given a final treatment as required to make

the texture of the patch to match with that of the surrounding material.

CURING OF PATCHED WORK

Immediately after patching is completed, the patched area shall be covered with an

approved non-staining, water saturated material which shall be kept wet and protected

against sun and wind for a period of 12 hours. Thereafter, the patched area shall be kept

continuously wet by a fine spray or sprinkling for not less than 10 days.

MISCELLANEOUS MATERIALS AND WORKS

PLYWOOD

The plywood for general purpose shall conform IS: 303.

Cementing together thin boards or sheets of wood into panels makes plywood. There are

always an odd number of layers, 3,5,7,9 ply etc. The plies are placed so that grain of each

layer is at right angles to the grain in the adjacent layer.

The chief advantages of plywood over a single board of the same thickness is that, plywood

offers more uniform strength, along its length and width and also offers greater resistance to

cracking and splitting with change in moisture content.

Usually synthetic resins are used for gluing, phenolic resins are usually cured in a hot press

which compresses and simultaneously heats the plies between hot plates, which maintain a

temperature of 900C to 1400C and a pressure of 11 to 14 Kg/cm2 on the wood. The time of

heating may be anything from 2 to 60 minutes depending upon the thickness. SPECIFICATION: PART A (CIVIL)

TENDER DOCUMENT

When water glues are used the wood absorbs so much water that the finished plywood must

be dried carefully. When synthetic resins are used as adhesive, the finished plywood must

be exposed to an atmosphere of controlled humidity until the proper amount of moisture has

been absorbed.

According to IS: 303, the plywood for general purpose shall be of the grades namely BWR,

WWR and CWR, depending upon the adhesives used for bonding the veneers, and it will be

further classified into six types namely AA, AB, AC, BB, BC and CC based on the quality of

the two faces, each face being of three kinds namely, A, B and C. After pressing, the finished

plywood should be reconditioned to moisture content not less than 8% and not more than

16%.

always an odd number of layers. The plies shall be placed, so that, grain of each layer Is at

right angles to the grain in the adjacent layer.

Plywood shall be waterproof, weatherproof, boil proof, and highly durable even against

strenuous vulnerable uses. It shall resist the attack of termites, cockroaches, wood

burrowers, fungus, mould, rot, decay and other wood destroying insects and marine
