(d) is substantially responsive to the requirements of the Bidding documents.
26.2 A substantially responsive Bid is one which conforms to all the terms, conditions, and specifications of the
Bidding documents, without material deviation or reservation. A material deviation or reservation is one (a)
which affects in any substantial way the scope, quality, or performance of the Works; (b) which limits in any
substantial way, inconsistent with the Bidding documents, the Employer's rights or the Bidder's obligations
under the Contract; or (c) whose rectification would affect unfairly the competitive position of other Bidders
presenting substantially responsive Bids.

responsive by correction or withdrawal of the non-conforming deviation or reservation.
27. Correction of Errors

Errors will be corrected by the Employer as follows:
(a) where there is a discrepancy between the rates in figures and in words, the rate in words 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 rejected, and the Bid security may be
forfeited in accordance with Sub-Clause 16.6 (b).

29. Evaluation and Comparison of Bids
29.1 The Employer will evaluate and compare only the Bids determined to be substantially responsive in
accordance with Clause 26.

(c) making appropriate adjustments to reflect discounts or other price modifications offered in
accordance with Sub Clause 22.5.
29.3 The Employer reserves the right to accept or reject any variation, deviation, or alternative offer. Variations,
deviations, and alternative offers and other factors which are in excess of the requirements of the Bidding
documents or otherwise result in unsolicited benefits for the Employer shall not be taken into account in Bid
evaluation.
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.
30. Deleted

3, and (b) qualified in accordance with the provisions of Clause 4.

ethics during the procurement and execution of such contracts.1 In pursuance of this policy, the Bank:
(a) defines, for the purposes of this provision, the terms set forth below as follows:
(i) ―corrupt practice‖2 is the offering, giving, receiving or soliciting, directly or indirectly, of
anything of value to influence improperly the actions of another party;

recklessly misleads, or attempts to mislead, a party to obtain a financial or other benefit or to
avoid an obligation;
(iii) ―collusive practice‖4 is an arrangement between two or more parties designed to achieve an
improper purpose, including to influence improperly the actions of another party;
(iv) ―coercive practice‖5 is impairing or harming, or threatening to impair or harm, directly or
indirectly, any party or the property of the party to influence improperly the actions of a party;
(v) "obstructive practice" is

and/or threatening, harassing or intimidating any party to prevent it from disclosing its
knowledge of matters relevant to the investigation or from pursuing the investigation; or
(bb) acts intended to materially impede the exercise of the Bank‘s inspection and audit rights
provided for under sub-clause 3.1 (e) below.

through an agent, engaged in corrupt, fraudulent, collusive, coercive or obstructive practices in
competing for the contract in question;

period stated by the Engineer-in-charge 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.

compound as per specification including 1.5 mm thick cement punning in the water contact face. 12 mm thick
plastering in 1:6 cement sand mortar in the outer face shall be provided. ―Cement Brick‖ will mean brick work
in cement sand mortar in proportion as mentioned above.
8.0 R.C.C. WORKS
The R.C.C. works are generally to be conducted by R.M.C. and shall be as per specification of I.S. codes, and
stated elsewhere in the specification and schedule of Tender Document. In a few cases as mentioned in
relevant Schedule of Work R.C.C. works with nominal mix M-15 & or M-20 Concrete shall be used as per
specification of relevant I.S. Code.
For major R.C.C works (Where concrete is specified by strength) the mix proportion should not be leaner than
1:2:4 so as to give ultimate crushing strength not less than 20 N/mm2 at 28 days cured under field condition.
The mix for the concrete is to be so adopted and the slump is to be so allowed as to give specified strength
and proper workability at the existing site conditions. Contractor shall remain fully responsible for producing
concrete of specified strength in the actual job and therefore cast at his own cost test specimens of 15 cm.
cubes as already specified during work and cure the same in similar way as for laid concrete for being tested
for strength.
Each set of test specimen shall be taken to cover the quantity of concrete laid on the job during the period
from the time of taking the previous set of specimens and the quantity will be estimated by the Engineer-in-
charge from records maintained by him.
The interior surface of the mould and base plate shall be lightly oiled before the concrete is placed in the
mould. When the job concrete is compacted by ordinary methods, the test specimen shall be molded by
placing the fresh concrete in the mould in three layers, each approximately one-third of the volume of the
mould. In placing each scoopful of concrete, the scoop shall be moved around the top edge of the mould as
the concrete there slides from it in order to ensure a uniform distribution of concrete within the mould. Each
layer shall be rodded, 25 times with a 16-mm. rod, 60 cm in length bullet pointed at the lower end. The
strokes shall be distributed in a uniform manner over the cross-section of the mould and shall penetrate into
the underlying layer. The bottom layer shall be rodded, throughout its depth. After the top layer has been
rodded, the surface of the concrete shall be struck off with at trowel and covered with a glass plate at least 6.5
mm. thick or a machined metal plate. The whole process of molding shall be carried out in such a manner as
to preclude the alteration of the water-cement ratio of the concrete, by loss of water either by leakage from the
bottom of overflow form the top of the mould.
When the job concrete is placed by vibration and consistency of the concrete is such that the test-specimens
cannot be properly molded by hand rodding as described above, the specimens shall be vibrated to give a
compaction corresponding to that of the job concrete. The fresh concrete shall be placed in the mould in two
layers each approximately half the volume of the mould. In placing each scoop full of concrete the scoop shall
be moved around the top edge of the mould as the concrete there slides from it in order to ensure a
symmetrical distribution of concrete within the mould. Either internal or external vibrator may be used. The
vibration of each layer shall not be continued longer than is necessary to secure the required density. Internal
vibrators shall be of appropriate size and shall penetrate only the layer to be compacted. In compacting the
first layer, the vibrators shall not be allowed to rest on the bottom of the mould. In placing the concrete for the
to player, the mould shall be filled to the extent that there will be no mortar loss during vibration. After
vibrating the second layer, enough concrete shall be added to bring the level above the top of the mould. The
surface of the concretes shall then be struck off with a trowel and covered with a glass or steel plate as
specified above. The whole process of moulding shall be carried out in such a manner as to preclude the
alternation of water-cement ratio of the concrete by loss of water either by leakage from the bottom or
overflow from the top of the mould.
77
After curing, the specimen properly wrapped shall be made over to the Engineer-in-charge or his
representative who will arrange to have them tested at 28 days from the date of casting. If there by any delay
for any reason whatsoever the result of the test shall nevertheless be valid and will be applicable as per rules
in case for all test specimens whatsoever. The contractor shall be responsible for proper packing of the
specimens at his own cost, for safe and convenient transport of the same from the site to the testing laboratory
.The cost of testing the test moulds and other charges including cost of carriage of the test moulds from the
work site to the particular laboratory (both ways) and other incidental charges in this connection will have to
be borne by the contractor.
In case of concrete showing, on the result of the cube tests, strength less than that as specified above in the
―Acceptance Criteria‖ but has s strength greater than that mentioned in the said ―Acceptance Criteria‖ concrete may,
at the discretion of the Engineer-in-charge, be accepted as being structurally adequate without further testing.
If the concrete is deemed not to comply the ―Acceptance Criteria‖, the structural adequacy of the parts
affected may by investigated as per provision of Clause 17.4 and/or clause 17.6 of I.S.456-2000 as the case
may be before rejection on the application of the Contractor with the undertaking to bear the cost of such
tests.
If the strength of the concrete is such that it satisfies provisions made in sub clause 17.4.3 and /or sub-clause
17.6.3. of IS: 456-2000, concrete in that member represented by such tests shall be considered acceptable but
the Engineer-in-Charge shall have the full power to fix the rate of deduction @ 100/- per cubic meter.
In case the test results do not satisfy the relevant requirement of the preceding paragraph, the Volume of
concrete so deficient shall be deemed to be unacceptable and shall be removed form the structure and replaced
by fresh concrete of specified strength and the contractor shall in that case have to carry out the instruction of
the Engineer-in-Charge irrespective of the amount of loss, inconvenience and difficulties involved.
The contractor shall remain liable to act / to carry out instruction under the provision of this clause
notwithstanding issuing by the Engineer-in-Charge of any certificates or the passing of any bills or accounts.
8.1 Mixing and Laying:
All concrete shall be mixed in Mechanical mixer and all concrete work in foundation; superstructure etc. shall
be properly vibrated with the help of mechanical vibrator as per direction of Engineer-in-charge. Concrete
Mixer Machine, Vibrator and all other tools and plants as required shall have to be arranged by the contractor
at his own cost.
8.2 Mortars and Concrete:
Contractors are particularly warned against the use of inferior materials (to that specified or approved) at site
or use of incorrect proportion of different materials in the make up of concrete or mortar. Detection of any
such practice will lead to rejection of all such works and imposition of penalty. Engineer-in-charge has the
right to reject any mortar or concrete, which does not conform to the specification. Cube tests for concrete are
to be done as per I.S. code at the cost of the contractor.
The water cement ratio is to be determined by proper slump test or as per provision of relevant I.S. In case of

period of hardening. It shall be so constructed that it may withstand the jerk and shock of vibration of
concrete.
Scaffolding must be strong and rigid stiffened with necessary cross bracings and proper deck at every stage
where casting work is in progress to prevent any injuries to persons and to facilitate inspection, supervision
and taking measurement at any time.
The hire and labour charges for staging, scaffolding, platform etc. as provided in the schedule of works is for the
entire construction work including shell wall of reservoir etc till completion of work and removing the same as
per direction and instruction of EIC.
8.12 Curing and Finishing:
The joint shall be cleaned off the gray cement slurry with wire/coir brush or trowel to a depth of 2 mm to 3
mm and all dust and loose mortar removed. Joints shall then be flush pointed with white cement . The floor
shall then be kept wet for 7 days. After curing the surface shall be washed and finished clean. The finished
floor and wall shall not sound hollow when tapped with a wooden mallet.
8.13 Verticality of structure:
The vertical members should be perfectly vertical and no deviation in x – axis and /or y- axis is admissible. The
Contractor should take adequate precautionary measures to ensure that the structure is constructed true to
plumb. Similarly all horizontal members of the structures should be truly horizontal.
9.0 TESTING OF CONCRETE:
9.1 Frequency of sampling:
9.1.1 Sampling 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.
9.1.2 Frequency – The minimum frequency of sampling of concrete of each grade shall be in accordance with the
following;
Quantity of Concrete in the Work, m3 Number of Samples
1-5 1
6-15 2
16-30 3
31-50 4
51 and above 4 plus one additional sample for each additional 50 m3 or
part thereof
80
9.1.3 Test Specimen- Three test specimens shall be made from each sample for testing at 28 days Additional cubes
may be required for various purposes such as to determine the strength of concrete at 7 days or at the time of
striking the form work or to determine the duration of curing , or to check the testing error. Additional cubes
may also be required for testing cubes cured by accelerated methods as described in IS: 9013-1978. The
specimen shall be tested as described in IS: 516-1959.
9.2 Test Strength of Sample:
The test strength of the sample shall be the average of the strength of three specimens. The individual
variation should not be more than ±15 percent of the average.
Concrete shall be handled from the place of mixing to the place of final deposit as rapidly as practicable by
methods which will prevent the segregation or loss of the ingredients .It shall be deposited as nearly as
practicable in the final position to avoid re-handling of flowing. Unless specially permitted by the Engineer-
In-Charge, concrete shall not be dropped freely from a height of more than 2 meters.
Before placing the concrete, the moulds shall be cleaned of shavings, pieces of wood or other rubbish. When
placing the concrete the finer materials must be carefully worked against the moulds so that the faces of
concrete shall be left perfectly smooth and free from honeycombing upon withdrawal of the moulds. Any
defect in this respect must be dealt with by the contractor as directed by the Engineer-in-charge without any
extra charges therefore.
Depositing concrete under water shall not be allowed without specific permission form the Engineer-in-
charge. The method of concreting to be adopted in such cases shall have to be previously approved by him.
During placing and also immediately after deposition, the concrete shall be thoroughly compacted by
ramming, spearing etc. until it has been made to penetrate and fill all the spaces between and around the steel
rods, around embedded fixtures, and into the corners of formwork in such a manner as to ensure a solid mass
entirely free from voids. If so directed by the Engineer-in-charge, in addition to usual ramming, spearing etc.
sufficient number and suitable type of vibrators may have to be used on important jobs to enable working with
a comparatively low water-cement ratio and ensure the maximum possible degree of compaction and
homogeneity. It is imperative that the work should be done quickly as well as efficiently and adequate number
of hands must therefore be employed to ensure this.
Concrete shall be placed and compacted in its final position before setting has commenced and shall not
subsequently be disturbed.
Concreting shall be carried out continuously up to construction joints the position and arrangement of which
shall be predetermined by the Engineer-in-charge or his representative. Any rest, pauses, such as for meal,
shall also be subject to his approval. All concreting work should be so programmed as not to necessitate work
at night. if for any reasons this becomes imperative, the contractor shall obtain previous permission of the
Engineer-in-charge or his representative and made proper lighting arrangements to his satisfaction.
9.3 Protections And Curing
The contractor shall adequately protect freshly laid concrete, about1 to 2 hours after its laying from too rapid
drying due to sunshine, drying due to sunshine, drying winds etc. and also form rains or surface water and
shocks About 24 hours after laying of concrete, the surface shall be cured by flooding with water of minimum
25 mm. depth or by covering with wet absorbent materials viz. layer of sacks, canvas, Hessian or similar
materials and shall be kept constant wet for a period of not less then 10 (ten) days from the date of placing the
concrete . The curing shall be done for a minimum period of 10 days. Over the foundation concrete the
masonry work may be started after 48 hours of its laying, but the curing of cement concrete shall be
continued shall be continued along with the masonry work for a minimum period of 10 days.
In case of cement concrete used as sub-grade for flooring, the flooring may be commenced within 48 hours of
the laying of sub-grade. In case it is not possible to do so due to exigencies of work, the sub-grade shall be
roughened with a steel wire brush without disturbing the concrete, wetted and neat cement slurry at the rate of
1.75 Kg of cement per square meter applied to the base before laying floor and full rate of APS/mosaic
flooring will be paid with the specific orders of the Engineer-in-charge. The curing to be continued along with
the top layer of flooring for a minimum period of 10 days.

the concrete deposited can be properly rammed. The Engineer-in-Charge or his representative will indicate the
positions where such joints may be made.
In the case of horizontal joints any excess mortar or laitance shall be removed from the surface after the
concrete is deposited and before it has set.
When the work has to be commenced on a surface which has hardened, such surface shall be well roughened and all
laitance removed ; the surface shall then be swept clean, thoroughly wetted and covered with a thin layer of mortar
composed of equal volumes of cement and such works shall be deemed to be covered by the rates for concrete.
