required securities and; (d) is substantially responsive to the requirements of the Bidding

documents.

reservation.

will govern; and

(b) where there is a discrepancy between the unit and the line item total resulting from

multiplying the unit rate by the quantity, the unit rate as quoted will govern.

27.2 The amount stated in the Bid will be adjusted by the Employer in accordance with the above

procedure for the correction of errors and, with the concurrence of the Bidder, shall be considered

as binding upon the Bidder. If the Bidder does not accept the corrected amount the Bid will be

29.4 The estimated effect of the price adjustment conditions under Clause 47 of the Conditions of

Contract, during the period of implementation of the Contract, will not be taken into account in

Bid evaluation.

29.5 If the Bid of the successful Bidder is seriously unbalanced in relation to the Engineer's estimate of

the cost of work to be performed under the contract, the Employer may require the Bidder to

produce detailed price analyses for any or all items of the Bill of Quantities, to demonstrate the

internal consistency of those prices with the construction methods and schedule proposed. After

evaluation of the price analyses, the Employer may require that the amount of the performance

security set forth in Clause 34 be increased at the expense of the successful Bidder to a level

sufficient to protect the Employer against financial loss in the event of default of the successful

Bidder under the Contract.

28.1 The Engineer shall extend the Intended Completion Date if a Compensation Event occurs or a

Variation is issued which makes it impossible for Completion to be achieved by the Intended

Completion Date without the Contractor taking steps to accelerate the remaining work and which

would cause the Contractor to incur additional cost.

28.2 The Engineer shall decide whether and by how much to extend the Intended Completion Date within 21

days of the Contractor asking the Engineer for a decision upon the effect of a Compensation Event or

Variation and submitting full supporting information. If the Contractor has failed to give early warning of

32.1 The Contractor is to warn the Engineer at the earliest opportunity of specific likely future events or

circumstances that may adversely affect the quality of the work, increase the Contract Price or delay the

provided by the Contractor as soon as reasonably possible.

32.2 The Contractor shall cooperate with the Engineer in making and considering proposals for how the effect

of such an event or circumstance can be avoided or reduced by anyone involved in the work and in

carrying out any resulting instruction of the Engineer.

C. Quality Control 33. Identifying Defects

33.1 The Engineer shall check the Contractor's work and notify the Contractor of any Defects that

are found. Such checking shall not affect the Contractor's responsibilities. The Engineer may

instruct the Contractor to search for a Defect and to uncover and test any work that the

Engineer considers may have a Defect.

33.2 The contractor shall permit the Employer’s Technical auditor to check the contractor’s work

and notify the Engineer and Contractor of any defects that are found. Such a check shall not

45

affect the Contractor’s or the Engineer’s responsibility as defined in the Contract

Agreement.

34. Tests

34.1 If the Engineer instructs the Contractor to carry out a test not specified in the Specification to

check whether any work has a Defect and the test shows that it does, the Contractor shall pay

for the test and any samples. If there is no Defect the test shall be a Compensation Event.

35. Correction of Defects

tolerance limits at reduced rates, Engineer will certify payments to Contractor accordingly.

D. Cost Control

37. Bill of Quantities

37.1 The Bill of Quantities shall contain items for the construction, installation, testing, and

commissioning work to be done by the contractor.

37.2 The Bill of Quantities is used to calculate the Contract Price. The Contractor is paid for the

quantity of the work done at the rate in the Bill of Quantities for each item.

38. Changes in the Quantities

38.1 If the final quantity of the work done differs from the quantity in the Bill of Quantities for

the particular item by more than 25 percent, provided the change exceeds 1% of Initial

Contract Price, the Engineer shall adjust the rate to allow for the change.

38.2 The Engineer shall not adjust rates from changes in quantities if thereby the Initial Contract

Price is exceeded by more than 15 percent, except with the Prior approval of the Employer.

38.3 If requested by the Engineer, the Contractor shall provide the Engineer with a detailed cost

breakdown of any rate in the Bill of Quantities.

39. Variations

39.1 All Variations shall be included in updated Programs produced by the Contractor.

40. Payments for Variations

46

40.1 The Contractor shall provide the Engineer with a quotation (with breakdown of unit rates)

for carrying out the Variation when requested to do so by the Engineer. The Engineer shall

assess the quotation, which shall be given within seven days of the request or within any

longer period stated by the Engineer and before the Variation is ordered.

40.2 If the work in the Variation corresponds with an item description in the Bill of Quantities

and if, in the opinion of the Engineer, the quantity of work above the limit stated in Sub

Clause 38.1 or the timing of its execution do not cause the cost per unit of quantity to

change, the rate in the bill of Quantities shall be used to calculate the value of the Variation.

If the cost per unit of quantity changes, or if the nature or timing of the work in the Variation

does not correspond with items in the Bill of Quantities, the quotation by the Contractor shall

be in form of new rates for the relevant items of work.

40.3 If the Contractor's quotation is unreasonable (or if the contractor fails to provide the

Engineer with a quotation within a reasonable time specified by the engineer in accordance

with Clause 40.1), the Engineer may order the Variation and make a change to the Contract

Price which shall be based on Engineer’s own forecast of the effects of the Variation on the

Contractor's costs.

40.4 If the Engineer decides that the urgency of varying the work would prevent a quotation being

given and considered without delaying the work, no quotation shall be given and the

Variation shall be treated as a Compensation Event.

40.5 The Contractor shall not be entitled to additional payment for costs that could have been

avoided by giving early warning.

41. Cash flow forecasts

41.1 When the Program is updated, the contractor is to provide the Engineer with an updated cash flow

forecast.

14 days certify the amounts to be paid to the Contractor after taking into account any credit

or debit for the month in question in respect of materials for the works in the relevant

amounts and under conditions set forth in sub-clause 51(3) of the Contract Data (Secured

Advance).

42.3 The value of work executed shall be determined by the Engineer after due check

measurement of the quantities claimed as executed by the contractor.

42.4 The value of work executed shall comprise the value of the quantities of the items in the Bill

of Quantities completed..

42.5 The value of work executed shall include the valuation of Variations and Compensation

Events.

42.6 The Engineer may exclude any item certified in a previous certificate or reduce the

proportion of any item previously certified in any certificate in the light of later information.

47

43. Payments

43.1 Payments shall be adjusted for deductions for advance payments, retention, other recoveries

in terms of the contract and taxes, at source, as applicable under the law. The Employer

shall pay the Contractor the amounts certified by the Engineer within 28 days of the date of

each certificate. If the Employer makes a late payment, the Contractor shall be paid interest

on the late payment in the next payment. Interest shall be calculated from the date by which

the payment should have been made upto the date when the late payment is made at 8% per

annum.

43.2 If an amount certified is increased in a later certificate or as a result of an award by the

Adjudicator or an Arbitrator, the Contractor shall be paid interest upon the delayed payment

as set out in this clause. Interest shall be calculated from the date upon which the increased

amount would have been certified in the absence of dispute.

43.3 Items of the Works for which no rate or price has been entered in will not be paid for by the

Employer and shall be deemed covered by other rates and prices in the Contract.

44. Compensation Events

44.1 The following are Compensation Events unless they are caused by the Contractor:

(a) The Employer does not give access to a part of the Site by the Site Possession Date

stated in the Contract Data.

(b) The Employer modifies the schedule of other contractors in a way which affects the

work of the contractor under the contract.

(c) The Engineer orders a delay or does not issue drawings, specifications or instructions

required for execution of works on time.

(d) The Engineer instructs the Contractor to uncover or to carry out additional tests upon

work which is then found to have no Defects.

(e) The Engineer unreasonably does not approve for a subcontract to be let.

(f) Ground conditions are substantially more adverse than could reasonably have been

assumed before issuance of Letter of Acceptance from the information issued to

Bidders (including the Site Investigation Reports), from information available publicly

and from a visual inspection of the Site.

(g) The Engineer gives an instruction for dealing with an unforeseen condition, caused by

the Employer, or additional work required for safety or other reasons.

(k) The Engineer unreasonably delays issuing a Certificate of Completion.

(l) Other Compensation Events listed in the Contract Data or mentioned in the Contract.

48

44.2 If a Compensation Event would cause additional cost or would prevent the work being completed

before the Intended Completion Date, the Contract Price shall be increased and/or the Intended

Completion Date is extended. The Engineer shall decide whether and by how much the Contract Price

shall be increased and whether and by how much the Intended Completion Date shall be extended.

44.3 As soon as information demonstrating the effect of each Compensation Event upon the Contractor's

forecast cost has been provided by the Contractor, it is to be assessed by the Engineer and the Contract

Price shall be adjusted accordingly. If the Contractor's forecast is deemed unreasonable, the Engineer

shall adjust the Contract Price based on Engineer’s own forecast. The Engineer will assume that the

Contractor will react competently and promptly to the event.

Note : The established values of standard Deviations shall be used. When adequate test

results (30 or more) are available and the target strengths revised thereafter. Efforts shall be

made to bring the standard Deviations up to date, preferably once a month.

Even though the Bill of quantities specifies various types of concrete, it is possible that the

type may be altered to suit the site conditions. The compressive strength indicated above

pertains to compressive strength tests on “work test cubes 15 x 15 x 15 cm, after normal

curing for 28 days. The strength of preliminary test cubes shall be as per IS : 456.

The type of concrete for any particular situation of work shall be as per drawings.

Any construction in the coastal areas may be considered as exposed to “severe”

environmental condition. In assessing the level of severity, it shall be prudent to adopt a

realistic attitude and be even some what conservative in respect of the extent of coastal zone

for the ultimate durability of the structures.

Thus, besides using. Portland Slag Cement, the specific requirement on “durability aspects”,

as per Indian Standard IS 456, in respect of the following parameters, must be met :-

76

Minimum Cement Content

Maximum Water / Cement ratio

Cover to Steel Reinforcement.

All these requirements are related to the various ‘environmental exposure conditions. The

standard IS 456 classifies the environment into 5 levels of severity, that is mild, moderate,

severe, very severe, and extreme.

The parameters relating to minimum cement content and maximum water / cement

ratio, as per IS 456, are summarized below along with the minimum grade of concrete

Arrangement for slump cone test shall be kept at site to arrive at workability whenever

theEngineer-in-charge wants to check at site. Arrangement for compacting factor test shall

also be made to Tests for determination of strength of concrete.

ii. Strength of Concrete

As will be apparent from the Bill of quantities, the strength of concrete specified is the criteria and the

contractor shall make every effort to obtain the strength by good quality. Control. In case of concrete,

which does not obtain the specified strength at 28 days, such work shall be demolished and

reconstructed to obtain the requisite strengths, as directed by the Engineer-in-charge. It has also to

be ensured that the concrete conforms to the durability requirements viz. all requisite parameters

concerning minimum cement content, maximum free water cement ratio and the specified cover to

steel as well as good workmanship to obtain full compaction of concrete with non honey-combing in

the finished concrete etc. have to be meticulously implemented on the job including fully efficient

curing of concrete surfaces. To determine whether concrete in any particular part of the work is of

the requisite strength or not, test cubes (works test cubes) shall be made from samples collected

from the concrete being poured for the particular part and determined as per acceptance criteria

detailed hereinafter. The salient features for the collection of samples is as indicated below.

Testing of Concrete Cubes for determining Compression strength:

1. Quality

77

As specified

2. Compression strength

Shall be as specified for the particular type of concrete.

3. Criteria for acceptance of work

Part or element pf concrete work shall be deemed to be acceptable, provided the three cubes tested for 28 days strength conform to the following as per IS 456.

iii. Acceptance criteria of concrete cubes. (As per IS 456)

The Concrete shall be deemed to comply with the strength requirements when both the following conditions are met.

(a) The mean strength – determined from any group of 4 non-over lapping consecutive test:

(b) Any individual test result complies with the appropriate limits in column 3 of the following Table-A

Whichever is greater fck = 28 days characteristic compressive strength

In the absence of established value of standard deviation, the following values of standard

deviation shall be assumed, and attempt should be made to obtain results of 30 samples as

early as possible to establish the value of standards deviation of the specified grade of concrete.

Assumed Standard Deviation Grade of Concrete Assumed Standard Deviation (N /mm

2)

M10 & M15 3.5 M20 & M25 4.0 M30, M35 & Above 5.0

The above values correspond to the site control having proper storage of cement’ weigh

batching of all materials; controlled addition of water regular checking of all materials’ aggregate

grading and moisture content; and periodical checking of workability and strength. Where there

is deviation from the table, the values give above shall be increased by 1 N /mm2.

78

Concrete shall be liable to be rejected if it is porous of honey combed, its placement has been

interrupted without providing a proper construction joint, the reinforcement has been displaced

beyond the tolerance specified or the construction tolerances have not been met. The concrete

shall be accepted only after the contractor carries out suitable remedial measures to the full

satisfaction of the Engineer-in-charge.

In case of doubt regarding the grade of concrete used, either due to poor workmanship or based

on results of cube strength tests, core tests shall be carried out. The points from which cores are

to be taken and the number of cores required shall be at the discretion of the Engineer-in-charge

and shall be representative of the whole of concrete concerned. In no case, however, shall fewer

than three cores be tested in accordance with IS – 516. Concrete in the member represented by

a core test shall be considered acceptable if the average equivalent cube strength of the core is

equal to at least 85% of the cube strength of the grade of concrete specified for the

corresponding age and no individual core has a strength less than 75%.

1.3.8 Quantum of Cubes and testing as per IS 456.

The minimum frequency of sampling of concrete of each grade shall be in accordance with

the following.

Quantity of Concrete No. of samples

In the work (m3)

1 - 5 1

6 - 15 2

16 - 30 3

31 - 50 4

51 and above 4 + one additional sample for

each additional 50 m3 or part there of.

NOTE: At least one sample shall be taken from each shift. 3 test specimens shall be made from

each sample for testing at 28 days. Additional 3 specimen cubes be cast to determine the strength of

concrete at 7 days.

The direction of the Engineer-in-charge in this regard shall be final and binding.

Batching and making of concrete:

All batching of aggregates and cement shall be by weight. All the necessary equipment such as

weighing equipment, devices for determination of moisture and bulk in sand, slump cone etc. shall

be provided by the contractor. Concrete shall be machine mixed in appropriate mechanical concrete

mixtures until there is a uniform distribution of materials and uniform colour and consistence is

achieved and under no circumstances for less than two and half minutes.

79

A wooden board approximately 30 cms. X 40 cms. Shall be put up at the concrete mixture on which

shall have been legibly written in English and the local language, the quality of concrete that is being

mixed, the proportions and other relevant data.

1.3.9 Cubes:

The size of cubes to be prepared and tested shall be 15 X 15 X 15 cm (6” x 6” x 6”)

Cubes each are intended for testing at 7 and 28 days respectively and determining the strength.

Cubes tested at 7 days should give a strength of not less than 70% of the corresponding strength of

structural members and also for works at various levels. It shall also be collected whenever the usual

quality for a particular strength is suspect. The acceptance criteria of concrete cubes as given above

and in IS: 456 is to be followed. The test results of the sample shall be the average of the strength of

3 specimens. The individual variation shall not be more than ± 15% of the average. If more, the test

results of the sample are invalid.

1.3.10 Preparation and Testing of Cubes:

Casting of cubes, preparation of moulds for the same, processing and curing the cubes and testing

the same shall be as per detailed instruction laid down in the relevant Indian Standard as amended

up to date.

1.3.11 Equipment modules testing etc.

It is entire responsibility of the contractor to prepare and get the cubes tested and provide for all

materials, labour, modules, equipment, faculty and charges for testing etc. The contractor’s rate for

concrete work shall be deemed to include for these and no extra payment whatsoever is admissible

on this account.

1.3.12 Slump:

The slump cone tests shall be required to be performed to establish workability and the same shall

be carried out free of cost. Suitable Plasticiser / Superplasticiser may need to be used, as directed

by the Engineer-in-charge, in M-20 M-30 & grade RCC to obtain therequisite workability of concrete

at the specified water cement ratio.

1.3.13 Form Work:

Form work shall be properly designed and constructed such that it is rigid enough to remain free

from bulging, sagging or replacement during placing of concrete. It should also be so constructed as

to facilitate removal of the same without damage to concrete. The formwork shall be adequately

watertight to prevent any loss of liquid and grout. All formwork shall be accurately erected in regard

to size, levels etc. In case of timber form work, the surface of forms in contact with concrete surface

shall be wrought. The joints between boards shall be close fitting and very thin for the concrete

surfaces designed to have exposed finish and not intended to be plastered. Surface of forms coming

in contact with concrete shall be treated with approved emulsions or mineral oil. It shall be ensured

that these emulsions do not stain or discolour the natural colour of concrete.

All form work shall be removed as per latest IS 456. Form work shall be removed without shock or

vibration. Edges of beams and columns if required to have chamfers shall be obtained by suitably

80

fixing triangular edge beads 20mm x 20mm to the forms. (No extra is admissible to the contractor on

account of these incidental and minor works for sizes up to and including 20mm x 20mm). Likewise

where drip notches are necessary they should be formed by suitably shaped fillets nailed in forms.

Form work for all beams and other horizontal construction members shall be built to an upward

camber of 1/300” of the span (in the center) to nullify the effects of optical

illusion. The camber shall be in addition to such camber as may be required and shown in the Static

Calculations.

The tolerance on the shapes, lines and dimensions shown in the drawings shall be within the

limits given below:

(i) Deviation from specified dimensions of cross-section of columns and beams……………………………..+ 12mm - 6 (ii) Deviation from dimensions of footings

1. Dimensions in plan…………………………+ 50mm - 12

2. Eccentricity………………………………….0.02 times the width of the Of deviation but not more than 50mm.

3. Thickness…………………………………...± 0.05 times the specified Thickness.

(iii) Plumb, specified Batter, the lines & surface of Columns walls etc…………………………….± 12 mm (in 3m of height) ± 18 mm (in 6m of height) & ± 30 mm (in 12m of height)

After the forms have been erected to line and grade, the same shall be meticulously inspected

as to their adequacy. If the forms are not tight, there will be 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 braced sufficiently to stay in alignment during concrete placement,

concreting operation shall not be commenced till the Contractor sets right the deficiencies and

the forms re-inspected and found O.K. it shall also be checked during inspection that the

formwork as erected conforms to the specified line, grade, alignment to the specified tolerance

limits. Fully adequate rigidity of forms is of paramount importance since the tolerance limits

specified are for the finished concrete and not for the forms. Consolidation of concrete by the

vibrator requires that the forms be tight and strong. Stability is a very important consideration in

the form work and the Contractor shall be made to understand that the common deficiencies

resulting in failure of formwork.

(i) Inadequate cross bracing: (ii) Inadequate horizontal bracing: (iii) failure to regulate the rate of

placement of concrete in the forms and (iv) abnormal form displacements during & after concrete

placement due to inadequate provision for lateral pressures.

The contractor should ensure that ready access is provided for proper placement of concrete,

vibration of concrete, and for inspection of these operations.

1.3.14 Horizontal Construction Joints :

81

A very common blemish on formed concrete surfaces in the off “set” often found at horizontal

construction joints where forms have given way (viz yielded) a fraction of couple of centimeters

at the bottom of the new lift. These off –sets should be prevented by so setting the forms as to fit

snugly & tight against the top of concrete in the previous lift and then securing the forms so as

to remain in tight contact during the concrete placement operation. 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 50 mm, though 25 mm lap is considered satisfactory.

The Contractor should take utmost care to ensure that the construction joints are smooth, free

from sharp deviations, projections or edges.

1.3.15 Spalling from the face of concrete :

Occasionally, spalling may occur from the face of concrete when forms are removed. This is

often caused by rough spots on the forms where mortar adheres strongly enough to overcome

the tensile strength of green concrete. Such areas on the forms must be cleaned, polished and

the covered with form oil by the contractor. Wire brushing of timber forms shall be done very

carefully to remove the set-mortar.

1.3.16 Filling of Bolt Holes

(she – Bolts ) or Holes of ties / Rods. The holes left in the concrete surfaces by the She – bolts

or rods etc. shall be duly reamed, cleared, cleaned and filled with – “dry pack mortar” by the

Contractor within a reasonable period of the removal of formwork. Such filling shall be made

flush with the concrete surface. No holes shall be left without the dry-pack mortar filling.

1.3.17 Inspection of Forms :

The Contractor shall inform the Engineer-in-charge well in time (well 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. However, such inspection

shall not relieve/ absolve the Contractor of his SOLE RESPONSIBILITY for the proper formwork,

and safety of men, materials, equipment and the consequent results / consequences.

1.3.18 Transporting and Pouring of Concrete :

No mixing of concrete shall be started unless the situation where they are to be poured are

prepared and kept ready. Concrete shall be poured immediately on preparation. Transporting of

concrete shall be done as speedily as possible and also in a manner to prevent segregation of

aggregates. No re-tempered concrete shall be allowed to be used on the works. No concrete

shall be allowed to fall from a height more than 1.2o Mt. Where the concrete is to be placed at

more depth it should be done through chute as directed by Engineer-in-charge.

Lift of concreting shall normally be not greater than 2.00 m in height.

Before fresh concrete is placed against an already cast and hardened section, such surfaces

shall be roughened, swept clean, moistened with water and treated with cement slurry. Fresh

concrete shall then be poured as required. Under no circumstances, concrete mixed for more

82

than 20 minutes shall be used where initial setting has commenced. Dewatering of excavations

for concreting where necessary shall be carried out by the contractor as directed and the rates

quoted by the contractor are deemed to be inclusive of such dewatering. No concreting shall be

done in adverse weather condition without proper precautions or approval from Engineer-in-

charge. No hand-mixing of concrete shall be allowed. In an exceptional / unavoidable

circumstance, it shall be allowed under the specific approval of Engineer-in-charge and that too

for a small or restricted quantity only , and in such a situation, 10% more cement shall be used

than that used when concrete ingredients are machine mixed.

1.3.19 Consolidation and processing of Concrete :

Concrete for all works shall be compacted by means of suitable vibrating equipment. Spare

vibrators needles which are in complete working condition shall always be kept ready at sites to

be put into commission incase of failure of the vibrators or needles under use. The vibrators shall

be operated by skilled personnel, thoroughly instructed as regards the mode, frequency, duration

etc. regarding vibration.

1.3.20 Finish to concrete surfaces :

Finish to concrete surfaces at various situations shall be as per directions of engineer-in-charge.

Where, form finish is specified, the final surface shall be smooth and even and no-undulations,

ridges, spots etc. shall be permitted. They shall be laid to pattern as directed. In case surfaces

intended and directed for form finish, exhibit any of the defects above mentioned, the surfaces

shall be rubbed with carborundum and finished as directed at the risk and cost of the contractor.

The decision as to the acceptability or otherwise of a surface will be notified by engineer-in-

charge and the contractor will implement the instructions accordingly. The honey-combed

concrete shall be meticulously rectified to the full satisfaction of the engineer-in-charge.

1.3.21 Concrete Cover for Reinforcement :

Where not specifically indicated in the drawings, concrete cover for reinforcement shall be as per

the latest Indian Standards and as per directions at site from time to time. Proper concrete cover

blocks to suite various covers as required shall be provided in adequate numbers sufficiently

ahead of the work.

In respect of the nominal cover to all steel reinforcements including links., it should not be less

than the following to meet the durability requirement ( as per IS 456:2000) :-

Exposure Environment Exposure classification Nominal concrete cover in mm not less than

Concrete surfaces sheltered from saturated air in coastal areas

Moderate 30

Concrete exposed to coastal environment

Severe 45

Concrete exposed to sea water spray / or in contact with

Very Severe 50

83

aggressive soils / water.

The actual cover should not deviate from the required nominal cover by +10mm and -

0mm.

1.3.22 Construction Joints :

Construction joints in concrete work shall be provided as far as possible only at predetermined

places in consultation with Engineer- in-charge. Joints shall be provided as specified in latest

Indian standards or as directed by Engineer-in-charge.

1.3.23 Curing :

It is very important that all cement concrete work shall be cured properly. All concrete work shall

be kept continuously in a damp or wet condition by pouring or by covering with a layer of moist

sack, canvas, hession or similar material for a minimum period of 14 days from the date of

concreting as per IS 456, prolonged curing beyond even 14 days shall be desirable (viz keeping

the concrete continuously wet). Since the Water –cement ratio of concrete shall be low (0.45 for

RCC M30 grade concrete & 0.5 for M20 grade concrete as per IS 456:2000 Table 5), it is all the

more important to ensure prevent of moisture loss from the concrete through fool-proof and

prolonged curing. Water used for curing shall also be free from any deleterious substances and

shall generally be fit for drinking. The work shall be adequately protected from drying, winds and

direct sun rays. The contractor should arrange at his own cost a temporary water supply line with

provision of suitable lines, pump etc. for curing and constructional purpose to reach all heights.

The contractor shall not be allowed to commence the work of concrete placement until he makes

all the curing arrangements to the full satisfaction of the engineer-in-charge (viz. water tanks,

pumps, delivery lines, spray nozzles etc. as well as the requisite crew earmarked specifically for

undertaking curing). Payment for the concrete placed shall be made only after its specified

curing has been done to the full satisfaction of the engineer-in-charge.

1.3.24 Membrane Curing :

Curring constitutes one of the most vital requirement for the strength & durability of concrete.

Any slackness in curing or doing inadequate curring will adversely affect the durability of

concrete. Fool-proof curring by the contractor is, therefore, a “must”. In case the Engineer-in-

charse finds that the moist curring(viz water curring) by the contractor is not being efficiently

done (particularly on the under sides of slabs & beams etc.), he shall direct him to resort to the

curring by membrane forming “curring compound”. The curing compound should be white

pigmented of approved quality conforming to ASTM-C-309-81 Type-2. This should meet the

requirement of water retention test as per ASTM designation C-158-80. Loss of water in this test

for acceptable curing compound should not be more than 0.55kg/m2 of exposed surface in 72

hours . The curing compound should also meet the day light reflectance test . Curing compound

is to be sprayed with a nozzle . It should be applied as soon as the bleeding water disappears

,leaving a dull appearance. This is when there is no free moisture on the surface. If applied too

early, the free moisture will prevent the compound from forming a moisture-proof film. If applied

too late, some of the moisture will have already been lost that should have been retained for the

hydration process. Proper time range will vary from about 30minutes to 2 hours after placement

84

of concrete depending upon humidity and temperature.Uniform coverage of curing compound on

the concrete surface is very important and, accordingly, it should be mechanically sprayed with a

nozzle. The dosage of curing compound sprayed on the concrete surface should normally be not

more than 1litre for about 3.75m2

(sq m) concrete surface area. The contractor shall be allowed

to use the curing compound only upon his furnishing its test reports in respect of the water

retention tests & day light reflectance test. The Engineer may also get the curing compound

tested in a reputed laboratory for its suitability. Payment for the concrete placed shall be made

only after the completion of proper application of membrane-forming curing compound.

1.3.25 Opening and inserts :

All opening and inserts which are designated in due time or as required for services, will be

exactly provided by the contractor including supply of materials. The contractor should also fix

the anchors or such items which maybe supplied by the proprietor in exact position and in

perfect lines and levels, inserts apply to such items as timber, dowels, bolts, loop, brackets,

suspension, irons, hooks , screws, plates, pipe, pipe of various types and diameter etc.

Openings in concrete or masonry must be provided in exact location, to correct shape, size and

depth or slightly bigger, as shown in drawings or as instructed. It must be clearly understood that

provisions of inserts and openings as contemplated in this contract are to be carried out with

“utmost precision” and any deviation of the same from that as shown in drawing or instructed

have to be rectified by the contractor at his own cost and responsibility. The contractor should

make provision of openings to deep beams and their members at bottom or at lower level as

necessary for cleaning purpose prior to concreting.

1.3.26 Steel reinforcement:

All reinforcement for concrete work shall be corrosion resistance steel (CRS 42) and conforming

strictly to the latest Indian Standards. They shall be of tested quality. Reinforcement shall be

fabricated to shapes and dimensions shown on the drawing and shall be placed where indicated

on the drawings or required to carry out the intent of drawing and specifications or as directed by

Engineer in charge. Before placing, reinforcement shall be thoroughly cleaned of loose rust,

coating etc. which would result in reducing or destroying the bond. Oiling the bars to clean them

is strictly prohibited. Bending, straightening, cutting etc. operations shall be carried out in a

manner not injurious to the material. Assembly of reinforcement, placing of reinforcement,

Tolerance for Cover, welding of joints etc. shall generally conform to the Indian Standard

specifications. IS 456.

1.3.27 Placing of Reinforcement.

Before the reinforcement is placed, the surfaces of bars and the surfaces of any metal bar

supports shall be cleaned of all rust, loose mill scale, dirt grease and any other objectionable

matter.

(ii) All reinforcement bars shall be accurately placed in exact position shown in drawings

and shall be securely held in position during placement of concrete by annealed

binding wire, and by using stays, blocks, metal chairs, spacers or other approved

devices at sufficiently close intervals (less than 1 m interval) so that the bars do not

sag.

85

(iii) Wire for binding reinforcement shall be soft and of annealed mild steel of 16 SWG

and shall conform to IS 280

(iv) The bars shall not be allowed to sag between the supports and also not allowed to

be displaced during concrete placement. Also, the contractor has to ensure that no

disturbance is caused to the reinforcement bars already placed in concrete.

(v) All devices used for positioning of bars shall be of non-corrodible material. Metal

supports shall not extend to the surface of concrete except where shown in the

drawings. Pieces of broken stone or brick or wooden block shall not be used.

(vi) The contractor must ensure that the CONCRETE COVER AS SPECIFIED IS

METICULOUSLY PROVIDED.

All bars protruding from concrete and to which other bars are to be spliced,

and which are likely to be exposed for a long period. SHALL BE PROTECTED BYA

THICK COAT OF NEAT CEMENT GROUT.

(vii) Reinforcing bars of 25 mm in diameter and less may be either lapped or but welded

whichever is considered more practical by the Engineer.

(viii) Reinforcing bars of 28 mm in diameter and larger may be connected by butt welding

provided that the lapped devices will be permitted if found to be more practical than

butt welding and furthermore that the lapping does not encroach on cover limitation

or hinder concrete or reinforcement placement. Electric are welding shall, preferably,

be used.

(ix) Tolerance for Cover. Unless specified otherwise, actual concrete cover should not

deviate from the required /specified nominal cover by + 10 mm.

All reinforcement shall be bent cold. Unless otherwise directed, reinforcement

shall not be spliced at points of maximum stresses. Engineer in charge shall be

informed of the same before such splicing is taken up. Laps and splicing shall

conform to the latest Indian Standards.

Reinforcement shall be accurately tied at all intersections and laps with 16

SWG soft drawn binding wire, such that the reinforcement will give a rigid structure.

Binding wire will not be measured or accounted for separately. The contractor’s rate

for reinforcement will be measured and paid for according to bending lists without

allowances for cutting, wastage, binding wire etc. authorised laps, hooks, chairs,

spacers etc. shall however be accounted for in case, the contractor or engineer

desires to resort to welding or swivel nuts, there shall however be made as if the laps

have been provided and no extra claim whatsoever shall be admissible on this

account

Reinforcement shall be assembled in place with proper concrete cover blocks

to suite various covers as required.

1.3.28 Measurements:

86

All measurements shall be as given below or where not given as per latest IS : 1200.

Concrete will be compensated for according to its actual volume.

The computation will be based upon the construction plans only and no site

measurements shall be taken for this purpose. All incidental work stated in the Technical

specifications and also dewatering at the time of concreting are deemed to have been

included for in the unit prices quoted by the contractor. Opening with an area larger than

0.1sqm shall be deducted from concrete quantity and where openings are smaller, these

shall not be deducted.

Form work will be measured and paid for according to their contact area. The unit

prices of the forms incorporates all scaffolds, nails, clamps, and all incidental work. Openings

with an area larger than 2m2 shall be deducted from work quantities and the form work

required for sides of such openings shall be paid for. Openings of less than 1 m2 area shall

surfaces shall be tested with a level and all jambs with a plumb bob as the work proceeds.

iv. Thickness:

The thickness of the plaster specified shall be measured exclusive of the thickness of the key

i.e. grooves or open joints in brickwork. The average thickness of plaster shall not be less

than the specified thickness. The minimum thickness of any portion of the surface shall not

be less than the specified thickness by more than 3mm. The average thickness should be

regulated at the time of plastering by keeping suitable thickness of the gauges. Extra

thickness required in dubbing behind rounding of corners at junctions of wall or in plastering

of masonry cornices etc. will be ignored.

Curing shall be started 24 hrs after finishing the plaster. The plaster shall be kept wet for a

period of 7 days. During this period it shall be suitably protected from all damages at the

contractor’s expense by such means as the engineer may approve. The dates on which

plastering is done shall be legibly marked on the various section plastered so that curing for

GUIDELINES FOR REHABILITATION OF BORROW/ QUARRY AREAS

General: The contractor is required to take quarry material only from licensed quarries. In the

case of existing quarries the contractor through the Engineer’s representative will have to ensure

that all actions in these quarries are in accordance with the environmentally sound and acceptable

manner.

In case the contractor establishes additional quarries and dedicated crusher plants, the

contractor has to ensure that all actions are in accordance with the environmental requirements.

In the case of borrow areas, Contractor need to specify a detailed arrangement including the

agreement with the owner of the land. The Contractor must comply with provisions of taxes,

levies, royalties etc. of the State.

Management Plan for Borrow / Quarry Areas

The contractor needs to develop a Borrow and Quarry area management plan providing at

least the following details:

Name, location and ownership of the borrow or quarry area;

Existing land use of the area (including the access road to be developed) to be quarried;

Approximate quantity of the material available;

The number of trees and the species of the trees to be removed;

Total area involved;

150

Arrangement with the owner;

Whether purchased or leased;

A statement from the owner saying the actual arrangement (not in terms of exact monitory

compensation) with him is agreeable for him;

The exact restoration plan indicating the number of trees that will be planted;

The action plan for leveling and landscaping in order to bring the area in conformity to the neighboring

land uses; and

The access roads rehabilitation.

Compliance certificate of tax, levy, royalty etc. provisions.

Rehabilitation of Borrow/ Quarry Areas

The objective of the rehabilitation programme is to reinstate the quarry /borrow pit sites to a safe and

secure area, which the general public should be able to safely enter and enjoy. Securing borrow pits

/quarry sites in a stable condition should be a fundamental requirement of the rehabilitation process. This

could be achieved by filling the quarry/ borrow pit with suitable materials to approximately the access

road level.

Quarries and borrow pits may be backfilled with rejected construction wastes and will be given a

vegetative cover. If this is not possible, then excavation slopes will be smoothed and depression will be

filled in such a way that it looks more or less like the original ground surface.

During works execution, the contractor shall ensure preservation of trees during piling of materials;

spreading of stripping material to facilitate water percolation and allow natural vegetation growth; re-

establishment of previous natural drainage flows; improvement of site appearance; digging of ditches to

collect runoff; and maintenance of roadways where a pit or quarry is declared useable water source for

livestock or people nearby. Once the works are completed, the contractor shall restore the environment

his own expense around the work site to its original splits.
