26.1 Prior to the detailed evaluation of Bids, the Employer shall determine whether each Bid (a) meets the eligibility criteria defined in ITB Clause 3; (b) has been properly signed; (c) is accompanied by the Bid Security; and (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.

26.3 If a Bid is not substantially responsive, it will be rejected by the Employer, and may not subsequently be made responsive by correction or withdrawal of the nonconforming deviation or reservation.

27. Correction of Errors

27.1 Bids determined to be substantially responsive shall be checked by the Employer for any arithmetic errors. Errors shall be corrected by the Employer as follows:

(a) where there is a discrepancy between the amounts in figures and in words, the amount in words shall govern; and

(b) where there is a discrepancy between the unit rate and the line item total resulting from multiplying the unit rate by the quantity, the unit rate as quoted shall govern, unless in the opinion of the Employer there is an obviously gross misplacement of the decimal point in the unit rate, in which


case the line item total as quoted shall govern, and the unit rate shall be corrected.

27.2 The corrections will be notified in writing to the individual bidder with a request for written acceptance of the corrections within the specified period as made in the notification. The amount stated in the Bid shall 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 shall be rejected, and the Bid Security may be forfeited in accordance with ITB Sub-Clause 16.5 (b).

28. Currency for Bid Evaluation

28.1 Bids shall be evaluated as quoted in Ngultrum (NU) in accordance with ITB Sub-Clause 14.1, unless a Bidder has used different exchange rates than those prescribed in ITB Sub-Clause 14.2, in which case the Bid shall be first converted into the amounts payable in different currencies using the rates quoted in the Bid and then reconverted to Ngultrum (NU) using the exchange rates prescribed in ITB Sub-Clause 14.2.

29. Evaluation and Comparison of Bids

29.1 The Employer shall evaluate and compare only the Bids determined to be substantially responsive in accordance with ITB Clause 26.

(a) making any correction for errors pursuant to ITB Clause 27;

(b) excluding provisional sums and the provision (unless no rates have been asked from the bidders), if any, for contingencies in the Bill of Quantities, but including Daywork,11 where priced competitively;

(c) making an appropriate adjustment for any other acceptable variations, deviations or alternative offers submitted in accordance with ITB Clause 17; and

(d) making appropriate adjustments to reflect discounts or other price modifications offered in accordance with ITB Sub-Clause 22.5.

29.3 The bids shall be evaluated by applying the evaluation criteria, sub criteria and points system specified in the BDS. Each responsive bid will be given a technical score. Financial bids of only those bidders who score the minimum technical score specified in the BDS will be considered to for the 2nd stage of bid evaluation to obtain an overall price preference -financial score. Work will be awarded to the Bidder obtaining the highest overall price preference -financial score which will be obtained using the following formula:

90 % X (Lowest quoted bid among qualifying tenders/ financial bid

11 Daywork is work carried out following instructions of the Employer and paid for on the basis of time spent by workers,

and the use of materials and the Contractor’s equipment, at the rates quoted in the Bid. For Daywork to be priced competitively for Bid evaluation purposes, the Employer must list tentative quantities for individual items to be costed against Daywork (e.g., a specific number of tractor driver staff-days, or a specific tonnage of Portland cement), to be multiplied by the bidders’ quoted rates and included in the total Bid price.


quoted by x) + 10% X Price preference score for x.

29.4 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.

29.5 The estimated effect of any price adjustment conditions under GCC Clause 47, during the period of implementation of the Contract, shall not be taken into account in Bid evaluation.

29.6 If the Bid which results in the lowest evaluated Bid price is abnormally low, seriously unbalanced and/or front loaded in the opinion of the Employer, the Employer shall require the Bidder to produce written explanations of, justifications and 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. Such explanations, justifications and analyses may also include, but are not limited to, details of the technical solutions chosen, exceptionally favorable conditions available to the Bidder for the execution of the Contract, and the originality of the Works proposed by the Bidder. After objective evaluation of the explanations, justifications and price analyses, taking into consideration the schedule of estimated Contract payments, if the Procuring Agency decides to accept the abnormally low, seriously unbalanced and/ or front loaded price, the bidder shall be required to provide additional differential security equivalent to the difference between the estimated amount and the quoted price in addition to the performance security.

Section VI: Special Conditions of Contract 39

Section V. General Conditions of Contract (GCC)

Notes on General Conditions of Contract

The General Conditions of Contract (GCC), read in conjunction with the Special Conditions of Contract and other documents listed therein, should be a complete document expressing fairly the rights and obligations of both parties. The form of General Conditions of Contract that follows has been developed on the basis of considerable international experience in the drafting and management of contracts, bearing in mind a trend in the construction industry towards simpler, more straightforward language. The form can be used directly for smaller ad measurement (unit prices or unit rates in a Bill of Quantities) contracts and, with the modifications noted in the footnotes, it can be adapted for lump sum contracts. The use of standard General Conditions of Contract for building and civil works will promote comprehensiveness of coverage, general acceptability of its provisions, savings in cost and time in Bid preparation and review, and the development of a solid background of legal case histories.

The Contractor’s attention is drawn to GCC Sub-Clause 59.1 [Corrupt or Fraudulent Practices] which provides, inter alia, that acts intended


materially to impede the exercise of the Employer’s inspection and audit rights provided for under GCC Sub-Clause 23.3 constitute a prohibited practice subject to contract termination (as well as to a determination of ineligibility pursuant to ITB Sub-Clause 2.1 (c) of the Instructions to Bidders within the Bidding Documents that preceded the placement of the Contract of which these GCC form a part).

24. Disputes 24.1 If the Contractor believes that a decision taken by the Project Manager was either outside the authority given to the Project Manager by the Contract or that the decision was wrongly taken, the decision shall be referred to the Adjudicator or Arbitrator within 14 days of the notification of the Project Manager’s decision.

25. Procedure for Disputes

25.1 The Adjudicator shall give a decision in writing within 30 days of receipt of a notification of a dispute.

25.2 The Adjudicator shall be paid by the hour at the rate specified in the BDS and the SCC, together with reimbursable expenses of the types specified in the SCC, and the cost shall be divided equally between the Employer and the Contractor, whatever decision is reached by the Adjudicator.

27.3 The Contractor shall submit to the Project Manager for approval an updated Program at intervals no longer than the period stated in the SCC. If the Contractor does not submit an updated Program within this period, the Project Manager may withhold the amount stated in the SCC from the next payment certificate and continue to withhold this


amount until the next payment after the date on which the overdue Program has been submitted.

27.4 The Project Manager’s approval of the Program shall not alter the Contractor’s obligations. The Contractor may revise the Program and submit it to the Employer again at any time. A revised Program shall show the effect of Variations.

27.5 An on-time completion out of a total of thirty (30) % scoring shall be done by the Program Manager. The contractor shall be penalized under this component if he fails to deliver the project as per the initial time-lines committed in the Program.

The site engineer shall penalize the contractor to an extent of 30%. The quantum of penalty could vary as following:

(i) 10% for a minor default (if the final completion of the project is delayed by 10 - 15% as compared to original project duration)

(ii) 20% for a medium default (if the final completion of the project is delayed by 15 - 25% as compared to original project duration)

(iii) 30% for a major default (if the final completion of the project is delayed by 25% or more as compared to original project duration.

28. Extension of the Intended Completion Date

28.1 The Project Manager shall extend the Intended Completion Date if 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, which would cause the Contractor to incur additional cost.

28.2 The Project Manager shall decide whether and by how much to extend the Intended Completion Date within 21 days of the Contractor asking the Project Manager for a decision upon the effect of Variation and submitting full supporting information. If the Contractor has failed to give early warning of a delay or has failed to cooperate in dealing with a delay, the delay by this failure shall not be considered in assessing the new Intended Completion Date.

29. Acceleration 29.1 When the Employer wants the Contractor to finish before the Intended Completion Date, the Project Manager shall obtain priced proposals for achieving the necessary acceleration from the Contractor. If the Employer accepts these proposals, the Intended Completion Date shall be adjusted accordingly and confirmed by both the Employer and the Contractor.

29.2 If the Contractor’s priced proposals for acceleration are accepted by the Employer, they are incorporated in the Contract Price and treated as a Variation.

30. Delays Ordered by the Project Manager

30.1 The Project Manager may instruct the Contractor to delay the start or progress of any activity within the Works.


31. Management Meetings

31.1 Either the Project Manager or the Contractor may require the other to attend a management meeting. The business of a management meeting shall be to review the plans for remaining work and to deal with matters raised in accordance with the early warning procedure.

31.2 The Project Manager shall record the business of management meetings and provide copies of the record to those attending the meeting. The responsibility of the parties for actions to be taken shall be decided by the Project Manager either at the management meeting or after the management meeting and stated in writing to all who attended the meeting.

Early Warning 32.1 The Contractor shall warn the Project Manager 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 execution of the Works. The Project Manager may require the Contractor to provide an estimate of the expected effect of the future event or circumstance on the Contract Price and Completion Date. The estimate shall be provided by the Contractor as soon as reasonably possible.

32.2 The Contractor shall cooperate with the Project Manager 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 Project Manager.

32.3 If the Contractor considers himself to be entitled to any extension of Time for Completion and/or any additional payment, under any Clause of these Conditions or otherwise in connection with the Contract, the Contractor shall give notice to the Project Manager, describing the event or circumstance giving rise to the claim. The notice shall be given as soon as practicable, and not later than 30 days after the Contractor became aware, or should have become aware, of the event or circumstance.

32.4 If the Contractor fails to give notice of a claim within such period of 30 days, the Employer shall be discharged from all liability in connection with the claim.

C. Quality Control 33. Identifying

Defects 33.1 The Project Manager 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 to ensure the quality of works executed. The Project Manager may instruct the Contractor to search for a Defect and to uncover and test any work that the Project Manager considers may have a Defect. The Project Manager at the end of the Contract shall issue a Performance score on Quality out of a total of 70 points based on the guidelines issued by the Standard and Quality Control Authority (SQCA).

34. Tests 34.1 If the Project Manager instructs the Contractor to carry out a test not

specified in the Specifications 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

35.1 The Project Manager shall give notice to the Contractor of any Defects before the end of the Defects Liability Period, which begins at Completion, and is defined in the SCC. The Defects Liability Period shall be extended for as long as Defects remain to be corrected.

35.2 Every time notice of a Defect is given, the Contractor shall correct the notified Defect within the length of time specified by the Project Manager’s notice.

36. Uncorrected Defects

36.1 If the Contractor has not corrected a Defect within the time specified in the Project Manager’s notice, the Project Manager shall assess the cost of having the Defect corrected, and the Contractor shall pay this amount to the Employer. At the option of the Employer, payment of such costs may be made in whole or in part by the Employer deducting and keeping for itself appropriate amounts from the Retention Money and/or claiming against any bank guarantee provided by the Contractor pursuant to GCC Sub-Clause 48.3.

D. Cost Control

37. Bill of

Quantities 19 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 20

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 twenty percent (20%), provided the cost of variation beyond twenty percent (20%) limit exceeds one percent (1%) of the Initial Contract Value the Employer shall adjust the quoted rate up or down to allow for the change. Only when both conditions are met then the quoted rate shall be changed.

(a) If the quantity of work executed exceeds the quantity of the item in BOQ beyond the higher specified limit the Employer shall fix the market rate (which may be lower or higher than the quoted rate) to be applied for the additional quantity of the work executed.

19 In lump sum contracts, delete “Bill of Quantities” and replace with “Activity Schedule,” and replace Sub-Clauses 37.1 and

37.2, as follows: 37.1 The Contractor shall provide updated Activity Schedules within 14 days of being instructed to do so by the

Employer. The activities on the Activity Schedule shall be coordinated with the activities on the Program. 37.2 The Contractor shall show delivery of Materials to the Site separately on the Activity Schedule if payment for

Materials on Site shall be made separately. 20 In lump sum contracts, delete “Bill of Quantities” and replace with “Activity Schedule,” and replace entire Clause 37with

new Sub-Clause 38.1, as follows: 38.1 The Activity Schedule shall be amended by the Contractor to accommodate changes of Program or method of

working made at the Contractor’s own discretion. Prices in the Activity Schedule shall not be altered when the Contractor makes such changes to the Activity Schedule.


(b) If the quantity of work executed is less than the quantity of the item in BOQ lesser than the lower specified limit, the Employer shall fix the market rate based on the submission of the contractor (which may be lower/higher than the quoted rate) to be applied for whole of the quantity of the work so executed.

38.2 The rates shall not be adjusted from changes in quantities if thereby the Initial Contract Price is exceeded by more than five percent (5%), except with the prior approval of the Employer in consultation with the Tender Committee.

38.3 If requested by the Project Manager, the Contractor shall provide the Project Manager with a detailed cost breakdown of any rate in the Bill of Quantities.

39. Variations 39.1 The Project Manager shall order any variation of the form, quality or quantity of the Works or any part thereof that may, in his opinion, be necessary. Each variation may include, but is not limited to, any of the following:

(a) increase or decrease in the quantity of any work included in the Contract,

(b) omission or insertion of any item of work,

(c) change in the character or quality or kind of any such work,

(d) change in the levels, lines, position and dimensions of any part of the

works, (e) additional work of any kind, or (f) change in any specified sequence or timing of construction activities.

39.2 The Project Manager shall make any such variation by issuing written

instructions to the Contractor and ensure that such variations are duly noted in the Site Order Register. A variation made shall not, in any way, vitiate or invalidate the Contract, but the effect, if any, of all such variations shall be valued in accordance with GCC Clause 40.

39.3 The Contractor shall execute and be bound by each Variation, unless the Contractor promptly gives notice to the Project Manager stating (with supporting particulars) that (i) the Contractor cannot readily obtain the Goods required for the Variation, or (ii) such Variation triggers a substantial change in the sequence of the progress of the Works. Upon receiving this notice, the Project Manager shall cancel, confirm or vary the instruction.

39.4 All Variations shall be included in updated Programs21 produced by the Contractor.

40. Payments for 40.1 The Contractor shall provide the Project Manager analysed rate for

21 In lump sum contracts, add “and Activity Schedules” after “Programs”.


Variations carrying out the Variation when requested to do so by the Project Manager. The Project Manager shall assess the analysed rates, which shall be given within seven days of the request or within any longer period stated by the Project Manager 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 Project Manager, the quantity of work above the limit stated in GCC 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 the form of new rates for the relevant items of work.22

40.3 If the Contractor’s quotation is unreasonable, the Project Manager may order the Variation and make a change to the Contract Price, which shall be based on the Project Manager’s own forecast of the effects of the Variation on the Contractor’s costs.

40.4 If the Project Manager 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.

M0 = Material Index for the month in which the tender was submitted;

M = the average value of the above Index Number for the 3 months period under review;

47.2 For the applications of the above formulae, the appropriate Index Numbers published by the National Statistical Bureau shall be adopted.

47.3 To the extent that full compensation for any rise or fall in costs to the contractor is not covered by the provisions of this or other clauses in the contract, the unit rates and prices included in the contract shall be deemed to include amounts to cover the contingency of such other rise or fall in costs.

All excavation operation shall include excavation and getting out the excavated matter. Getting out shall include throwing the excavated earth at least one metre or half the depth of excavation whichever is more, clear off the edge of excavation. The subsequent disposal of the excavated material shall either be as directed by the Engineer under a separate item or as included in this item disposal upto 50 meters lead. Excavation shall be dug out to the exact dimensions as shown in the drawing or as directed by the Engineer. Care shall be taken to cut the sides and bottom exactly to the required shape, slope and gradient, while carrying out excavation for drains work. The surface shall be dressed properly. If the excavation is done to a depth greater than that shown in the drawings or greater than that required by the Engineer, the excess depth shall be made good at the cost of the contractor with the stiff clay puddle at places where the drains are required to be pitched and with ordinary earth, properly watered and rammed, where the drains are not required to be pitched. In case the drain is required to be pitched, the back filling with clay puddle shall be done side by side as the pitching works proceeds. The brick pitched storm water drains shall be avoided as far as possible in filled up areas. Excavation in ordinary rock shall be carried out by crowbars, pickaxes or pneumatic drills. Blasting operations are generally not required in this case. If the contractor wishes to resort to blasting, he can do so with the permission of Engineer, but nothing extra will be paid to him on this account. Excavation in hard rock shall be done by chiseling where blasting operation is prohibited or is not applicable. In trenches or drains where blasting is not otherwise prohibited, the excavation in hard


rock shall be carried out by blasting in the first instance and finally by chiseling so as to obtain the correct section of the trench as per drawing. The blasting operation shall be strictly as per latest RGOB blasting manuals. Measurement: The length, breadth and depth shall be measured correct to 10 mm. The cubical contents shall be worked out to the nearest two places of decimal in cubic metres. Rate: The rates shall cover the cost for carrying out all the required excavation and banking operations including cost of labour, materials, equipment hired/owned, tools and plants, and incidentals necessary to complete the work. In case of rock, the rate shall also include the cost of all operations of blasting with explosive and accessories as mentioned above. Due protection and supporting shall be provided for the existing services like pipes, water mains and cables met within the course of excavation. Care shall be taken not to disturb electric and communication cables, and if necessary for removal it shall be arranged by the Engineer.

After 24 hours of laying of concrete, the surface shall be cured by flooding with water of minimum 25mm depth, or by covering with wet absorbent materials. The curing shall be done for a minimum period of 14 days. In special cases, curing may have to be done for more number of days as required by the Engineer. 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 along with the masonry work for a minimum period of 14 days. Where cement concrete is used as sub-grade for flooring, the flooring may be commenced before the curing period of sub-grade is over but the curing of sub-grade shall be continued along with the top layer of flooring for a minimum period of 14 days. The water used for curing shall not produce any objectionable stains or unsightly deposit on concrete surface. In special circumstances and locations curing by other means such as sealing material insulating blankets etc. may be adopted with the specific prior approval of the Engineer. The minimum compressive strength of mix 1:1.5:3 and 1:2:4 shall be as follows:

Mix Compressive strength in kg/sq.cm At 28 days

F RCC Works F1 Providing and fixing centering and shuttering in cluding strutting, propping etc. and removal of formwork. RC0003- In buttress, pilasters etc RC0090- In Foundation and plinth RC0093- in columns, pillars, post, strut etc. RC0095-Suspended floor, roof, landings, shelves and their supports, balconies, chajjas etc. Propping and centering: Props used for centering shall be of steel, timber posts, ballies or any other material approved by Engineer. Use of brick masonry pillars in mud mortar shall also be permissible. In no case ballies shall be of diameter less than 100mm measured at mid length and 80mm at thin end. Maximum permissible spacing shall be 1.2.m center to center. Ballies shall rest squarely on wooden sole plates of 40mm thickness and minimum bearing area of 0.1 sq.m laid either on ground or on 40 x 40cm brick masonry pillars in mud mortar of height not exceeding 40 cm. Double wedges shall further be provided between the sole plates and the wooden props so as to facilitate tightening and easing of shuttering without jarring the concrete. In case brick masonry pillars of adequate section are used instead of props, wooden sole plates shall be provided at the top of the pillars and double wedges inserted between the sole plate and the bottom of shuttering. Formwork and concreting of upper floor shall not be done until concrete of lower floor has set for atleast 28 days. In case of balconies and cantilever beams, coming one above the other, the members being cast shall be supported by props on two floors below the floor where initial supporting has been done. Ballies shall rest squarely on wooden sole plates of 40mm thickness and with minimum bearing area of 0.1 sq.m. The details of formwork stated above shall be applicable for spans of 4.5m and height upto 3.50 metres. In case any of these limits is exceeded the formwork shall be properly designed for the self-weight, weight of reinforcement, weight of fresh concrete, various live loads imposed during the construction process (such as workmen and equipment). Dumping of concrete, movement of construction equipment and action of the wind may produce lateral forces which must be resisted by the formwork to prevent lateral failure for which suitable horizontal as well as diagonal bracings shall be provided. The permissible stresses in bending, buckling load of props, permissible deflection of shuttering should not be exceeded.


In case the height of centering exceeds 3.50 metres, the props may be provided in multi-stages. Before the concreting is started, the props and wedges shall be thoroughly checked to see that these are intact, and take suitable action incase these are loose. While the concreting is in progress, at least one carpenter shall be readily available at the site. The carpenter shall keep a constant watch on the props and take immediate remedial measures, as soon as any of these get loosened. Care shall be taken that props and wedges do not get loose for a minimum period specified in table below. Shuttering: The shuttering shall have smooth and even surface and the joints shall not permit leakage of cement grout. Timber used shall be well seasoned, free from loose knots, projecting nails, splits or other defects that may mark the cement surface of concrete. It shall not be so dry as to absorb water from concrete ad swell and bulge, or so green or wet as to shrink after erection. Species of timber that are not affected appreciably by its contact with water shall be used. The timber shall be accurately sawn and planed on the sides and surface coming in contact with concrete. For exposed concrete faces, timber for shuttering shall be wrought on all faces in contact with concrete. Wooden formwork with metal sheet lining or steel plates stiffened by steel angles shall also be permitted. Where metal forms are used, all bolts and nuts shall be countersunk and well ground to provide a smooth plane surface. The chamfers, beveled edges and mouldings shall be made in the formwork itself. Opening for fan clamps and other fittings connected with services shall be provided in the shuttering as directed by the Engineer-in-charge. As far as practicable, clamps shall be used to hold the form together. Where use of nails is unavoidable minimum number of nails shall be used and these shall be left projecting so that they can be easily withdrawn. Use of double head nails shall be preferred. Surface Treatment for Shuttering: The surface of timber shuttering that would come in contact with concrete shall be well wetted and coated with soap solution, raw linseed oil, form oil of approved manufacture or any other approved material (such as polythene/polyethylene sheets), to prevent adhesion of concrete to form work. Soap solution, for the purpose shall be prepared by dissolving yellow soap in water to get the consistency of paint. Inside surfaces of forms shall be thoroughly cleaned before application of any of the materials mentioned above. Release agents shall be applied strictly in accordance with the manufacturers’ instructions and shall not be allowed to come in contact with any reinforcement. Re-use of shuttering will be permitted only after the inside surface has been thoroughly cleaned in the manner described above. Contractor shall give the Engineer due notice before placing any concrete in the forms to permit him to inspect and accept the form work as to its strength alignment and general fitness, but such inspection shall not relieve the contractor of his responsibility for safety of workman, machinery, materials and for results obtained. Camber: Suitable camber shall be provided in horizontal members of structures, especially in long spans to counteract the effects of deflection. The formwork shall be so assembled as to provide for such camber. The camber for beams and slabs shall be 4 mm per metre or as directed by the Engineer, so as to offset the subsequent deflection. For cantilevers, the camber at free end shall be 1/50th of the projected length or as directed by the Engineer. Special formwork: For special type of work-locations like tall structures etc. use of special types of formwork like moving or climbing forms shall be permitted. The details of such formworks along with the sequence of working shall be got approved from the Engineer before erection. Removal of Form Work: No formwork or any part thereof shall be removed without prior approval of the Engineer. The formwork shall be so removed as not to cause any damage to concrete due to shock or vibration. In a slab and beam construction, sides of beam shall be stripped first, then the under sides of slab and lastly the underside of the beam. Formwork must be so designed that they can be stripped in the order required i.e. (a) Shutters to vertical (non load bearing) faces e.g. column boxes, beams sides, wall forms,


(b) Shutters forming soffits to slabs, horizontal and inclined which carry only light load, e.g. slabs, roof, floors and canopies etc. (c) Soffit shutters carrying heavy load e.g. beam and girder bottoms. The whole of the formwork should be planned and a definite scheme of operation worked out. In no circumstances should forms be struck until the concrete reaches strength of at least twice the stress to which the concrete may be subjected at the time of striking. Where possible the from work should be left longer as it would assist curing. Forms should be eased carefully in order to prevent the load being suddenly transferred to concrete. The period that shall elapse after the concrete has been laid, before easing and removal of centering and shuttering is under taken shall be as given in table below:

Type of Formwork Minimum period before striking

Vertical formwork to columns, walls and beams 16-24 h

Soffit formwork to slabs (props to be refixed immediately after removal of formwork)

3 days

Soffit formwork to beams (props to be refixed immediately after removal of formwork )

7 days

Props to slabs spanning upto 4.5 m 7 days Props to slabs spanning over 4.5 m 14 days Props to beams and arches spanning upto 6 m 14 days

Props to beams and arches spanning over 6 m 21 days

Note 1: For rapid hardening cement, 3/7 of the above periods will be sufficient in all cases, except for vertical sides of slabs, beams and columns which should be retained for atleast 24 hours. Note 2: In case of cantilever slabs and beams, the centering shall remain till structures for counter acting or bearing down have been erected and have attained sufficient strength. Note 3: Proper precaution should be taken to allow for the decrease in the rate of hardening that occurs with all cements in cold weather. Note 4: Work damaged through premature or careless removal of forms shall be reconstructed Measurement: Where it is stipulated that the formwork shall be paid separately, measurement will be taken of the area of shuttering in contact with the concrete surface. Dimensions of formwork shall be measured correct to 10 mm. The measurements shall be taken separately under each of the items mentioned above. Centering and shuttering exceeding 3.5 metres height in one floor shall be measured and paid for separately. Where it is not specifically stated in the description of the item that formwork shall be paid for separately, the rate of the R.C.C. item shall be deemed to include the cost of formwork. No deductions from the shuttering due to openings/ obstructions shall be made if area of such openings/obstructions does not exceed 0.1 sq.m. Nothing extra shall be paid for forming such openings. Rate: The rate of formwork includes the cost of labour, materials, tools and plant required for all the


operations described in this section including properly supporting the members until the concrete is cured, set and hardened as required. No separate payments shall be made for items such as from release agent, connections, provisions for openings and other items required for the completion of the work unless specified otherwise. F2 Providing and fixing, thermo-mechanically treate d reinforcement bar (Yield strength 500MPa) for R.C.C. work including cutting, bending and placing in position in complete. The type and grade of reinforcement to be used shall be as indicated on the drawings. Where this information is not given on the drawings, hot rolled deformed bars having yield strength of 415 mpa shall be used. Bars shall be bent cold (no heating shall be permitted), correctly to the size and shape as shown on the detailed drawings or as directed by the Engineer. Preferably, bars of full length shall be used and within the following tolerances: Dimension Tolerance. Length of straight bars ± 25 mm Location of splices ± 50 mm Length of lap splices ± 50 mm Minimum clear cover shall be as indicated on the drawings. Where cover is not indicated on the drawings, it shall be in accordance with the following: Location Clear cover Slabs 20 mm Beams – main reinforcement 30 mm Beams – stirrups 20 mm Columns – main reinforcement 40 mm Column – ties 20 mm Footings 75 mm Overlapping of bars shall be as indicated in the drawings. The overlapping bars shall not touch each other and these shall be kept apart by 25 mm or 1.25 times the maximum size of the coarse aggregate whichever is greater, with concrete between them. But where this cannot be done, the overlapping shall be bound together at intervals not exceeding twice the dia. of such bars, with two strands of annealed steel wire of 0.90 mm to 1.6 mm thickness twisted tight. The overlaps shall be staggered for different bars and located at points, along the span, where neither shear nor bending moment is maximum. Where lap length is not explicitly shown on the drawings, the length shown in the following table shall be used: Bar Size. Lap length. 10 mm 300 mm 12 mm 350 mm 16 mm 600 mm 20 mm 900 mm 25 mm 1000 mm The ends of rods shall be bent in to semi circular hooks, having clear diameter equal to four times the diameter of the bar, with a length, beyond the bend equal to four times the diameter of the bar. End hooks may, however, not be provided for cold twisted, hot rolled and CRS bars. Note: Welding should not be used unless absolutely necessary. Reinforcement bar does not weld very well and the resulting splice can be a weak spot. Binding is better as welding can produce a reduction in strength as well.


Reinforcement bars shall be placed in position as shown in the drawings. The bars crossing one another shall be tied together at every intersection with two strands of annealed steel wire 0.90 to 1.6 mm thickness twisted tight to make the skeleton of the steel work rigid so that the reinforcement does not get displaced during the deposition of concrete. The bars shall be kept in position by the following methods: (a) In case of beam and slab construction, pre-cast cover blocks in cement mortar 1:2 (cement: 2 coarse sand), about 4cm x 4cm section and of thickness equal to the specified cover shall be placed between the bars and shuttering, so as to secure and maintain the requisite cover of concrete over reinforcement. (b) In case of cantilevered and double layer reinforced beams or slabs, the vertical distance

between the horizontal bars shall be maintained by introducing chain spacers or support bars of steel at 1.0 metre or at shorter spacing to avoid sagging.

(c) In case of columns and walls, the vertical bars shall be kept in position by means of timber templates with slots accurately cut in them, or with block of cement mortar (1:2) suitably tied to the reinforcement. (d) In case of other R.C.C. structure such as arches, domes etc. cover blocks, spacers and templates shall be used as directed by the Engineer. Measurement: Reinforcement including authorized spacer bars and laps shall be measured in lengths of different diameters, as actually used in the work nearest to 10 mm and their weight calculated on the basis of standard tables. Wastage and un-authorized over laps shall not be paid for. Annealed steel wire required for binding or tack welding shall not be measured, its cost being included in the rate of reinforcement. Wherever welding is resorted to in lieu of over laps such welds shall be measured separately in members for different size of reinforcement. Rate: The rate for providing reinforcement shall include the cost of labour and materials as required for all operations described above except welding in lieu of over laps, which shall be paid for separately. No Separate payment will be made for concrete spacer blocks, timber templates, tie wire or any other accessories required for the performance of the work. F3 RC0010. 1:1.5:3 (1cement: 1.5 sand: 3 graded cr ushed rock, 20mm nominal size.) Providing and laying in position reinforced cement concrete work in plinth and skirting courses, fillets, columns, pillars, posts and strut s upto floor five level excluding the cost of centering, shuttering and reinforcement. F4 RC 0014. 1:1.5:3 (1cement:1.5sand:3 graded crus hed rock, 20mm nominal size) Providing and laying in position reinforced cement concrete work in suspended floor, roofs having slope upto 15 degrees, landings, balconies, shelves & chajjas upto floor five level excluding the cost of centering, shuttering & reinf orcement (slab) Concreting shall be commenced only after the Engineer has inspected the centering, shuttering and reinforcement as placed and passed the same. In case of concreting slab and beams; wooden plank or cat- walks supported directly on the centering by means of wooden blocks or logs shall be provided to convey the concrete to the place of deposition without disturbing the reinforcement in any way. Labour shall not be allowed to walk over the reinforcement. In case of columns and walls, it is desirable to place concrete without construction joints. The programme of connecting in the vertical direction shall be restricted to one metre per hour. The concrete shall be deposited in its final position in a manner to preclude segregation of ingredients. In deep trenches and footings, concrete shall be placed through chutes as directed by the Engineer. In case of columns and walls the shuttering shall be so adjusted that the vertical drop of concrete is not more than 1.5 meters at a time.


Cold weather concreting: During cold weather, as a rule concreting shall not be done when the temperature falls below 4.5 oC. However in circumstances where it becomes necessary to deposit concrete at or near freezing temperatures, precautions shall be taken to ensure that at the time of placing it has a temperature of not less than 4.5 oC and that this temperature is maintained till the concrete is compacted and it is thoroughly hardened. When necessary, the ingredients shall be heated before mixing and concrete carefully protected after placing; in general heating mixing water alone to about 60 oC may be sufficient for this purpose. Dependence shall not be placed on salt or other chemicals for the prevention of freezing. (Use of calcium chloride to accelerate the rate of hardening is not permitted as it is considered harmful). Concrete placed shall be protected against frost by suitable covering. Concrete damaged by frost shall be removed and redone. Hot weather concreting: During hot weather, precaution shall be taken to see that the temperature of wet concrete does not exceed 38 o C. No concrete shall be laid within half an hour of the closing time of the day, unless permitted by the Engineer. It is necessary that the time between mixing and placing of concrete shall not exceed 30 minutes so that the initial setting process is not interfered with. Concrete shall be compacted into a dense mass immediately after placing, by means of mechanical vibrators designed for continuous operation. The Engineer may however, relax this condition at his discretion for certain items, depending on the thickness of members and feasibility of vibrating the same, and permit hand compaction instead. Hand compaction will be done with the help of tamping rods so that concrete is thoroughly compacted and completely worked around the reinforcement, embedded fixtures, and into corners of the formwork. The layers of concrete shall be so placed that the bottom layer does not finally set before the top layer is placed. The vibrators shall maintain the whole of concrete under treatment in an adequate state of agitation, such that de-aeration and effective compaction is attained at a rate commensurate with the supply of concrete from the mixers. The vibration shall continue during the whole period occupied by placing of concrete, the vibrators being adjusted so that the center of vibrations approximates to the center of the mass being placed at the time of compacting. Concrete shall be judged to be properly compacted, when the mortar fills the spaces between the coarse aggregate and begins to cream up to form an even surface. When this condition has been attained, the vibrator shall be stopped in case of vibrating tables and external vibrators. In case both internal and external vibrators are being used the internal vibrators shall be first withdrawn slowly after which the external vibrators shall be stopped so that no loose pocket is left in the body of the concrete. The specific instructions of the makers of the particular type of vibrator used shall be strictly complied with. Shaking of reinforcement for the purpose of compaction should be avoided. Compaction shall be completed before the initial setting starts, ie. within 30 minutes of addition of water to the dry mixture. Construction Joints: Concreting shall be carried out continuously upto the construction joints, the position and details of which shall be shown in Structural drawing or as indicated in this specification or as directed by the Engineer. Such joints shall be kept to the minimum and shall not be located in valleys. The joints shall be kept at places where the shear force is the minimum and these shall be straight and at right angles to the direction of main reinforcement. In case of columns, the joints shall be horizontal and minimum of 20 cm below the bottom of the beam running into the column head. The portion of the column between the stopping off level and the top of the slab shall be concreted with the beam. When stopping the concrete on a vertical plane in slabs and beams, an approved stop-board shall be placed with necessary slots for reinforcement bars or any other obstruction to pass the bars freely without bending. The construction joints shall be keyed by providing a triangular or trapezoidal fillet nailed on the stop-board. Inclined or feather joints shall not be permitted. Any concrete flowing through the joints of stop-board shall be removed soon after the initial set. When concrete is stopped on a horizontal plane, the surface shall be roughened


and cleaned after the initial set. When the work has to be resumed, the joint shall be thoroughly cleaned with wire brush and loose particles removed. A coat of neat cement slurry at the rate of 2.75 kg of cement per square metre shall then be applied on the roughened surface before the fresh concrete is laid. Expansion Joint: Expansion joints shall be provided as shown in the structural drawings or as indicated in this specification or as directed by the Engineer including all formwork and labour necessary to form. Curing: After the concrete has begun to harden i.e. about 1 to 2 hours after it’s laying, it shall be protected from quick drying with moist gunny bags, sand or any other material approved by the Engineer. After 24 hours of laying of concrete, the surface shall be cured by flooding with water of minimum of 25 mm depth, or by covering with wet absorbent material. The curing shall be done for a minimum period of 14 days. In case of roof slabs, the top surface shall be finished even and smooth with wooden trowel, before the concrete begins to set. Immediately on removal of forms, the Engineer shall examine the R.C.C. work before any defects are made good such as: The work has sagged or contains honeycombing to an extent detrimental to structural safety or architectural concept shall be rejected. Surface defect of a minor nature may be accepted. On acceptance of such work by the Engineer, the same shall be rectified as follows: Surface defects which require repair when forms are removed usually consist of bulges due to movement of forms, ridges at form joints, honeycombed areas, damage resulting from the stripping of forms, and bolt holes. Bulges and ridges are to be removed by careful shipping or tooling and the surface is then rubbed with a grinding stone. Honey combed and other defective areas must be chipped out , the edges being cut as straight as possible and perpendicularly to the surface, or preferably slightly undercut to provide a key at the edge of the patch. Shallow patches are first treated with a coat of thin grout composed of one part of cement and one part of sand and then filled with mortar similar to that used in the concrete. The mortar is placed in layer not more than 10mm thick and each layer is given scratch finish to secure bond with the succeeding layer. The last layer is finished to match the surrounding concrete by floating, rubbing, or rooting on formed surfaces by pressing the form material against the patch while the mortar is still plastic. Large and deep patches require filling up with concrete held in place by forms. Such patches are reinforced and carefully dowelled to the hardened concrete. Holes left by bolts are filled with mortar carefully packed into place in small amounts. The mortar is mixed as dry as possible with just enough water so that it will be tightly compacted when forced into place. Tiered holes extending right through the concrete may be filled with mortar with a pressure gun similar to the gun used for greasing motorcars. Normally, patches appear darker than the surrounding concrete, possibly owing to the presence on their surface of less cement laitance. Where uniform surface colour is important, this effect shall be remedied by adding 10 to 20 percent of white Portland cement to the patching mortar, the exact quantity being determined by trail.


The same amount of care to cure the materials in the patches should be taken as with the whole structure. Curing must be started, as soon as possible, after the patch is finished to prevent early drying. Damp Hessian may be used but in some locations it may be difficult to hold it in place. A membrane-curing compound in these cases will come in most convenient. The surface, which is to receive plaster or where it is to be jointed with brick masonry wall, shall be properly roughened immediately after the shuttering is removed, taking care to remove the laitance completely without disturbing the concrete. The roughening shall be done by hacking. Before the surface is plastered it shall be cleaned and wetted so as to give good bond between concrete and plaster. The R.C.C. work shall be done carefully so that the thickness of plaster required for finishing the surface is not more than 6 mm. The surface of R.C.C. slab on which the cement concrete or mosaic floor is to be laid shall be roughened with brushes while the concrete is green. This shall be done carefully without disturbing the concrete. Grades of Concrete: A minimum characteristic cube strength at 28 days of 20 N/mm2 is required for RCC members. Further to this, the concrete making materials shall be purchased from a specific source for all types of concrete works. The maximum nominal aggregate size is 20mm for all RCC works. The concrete shall be capable of being transported and readily compacted by internal vibrators into a dense impermeable mass without segregation, bleeding or plastic cracking. Subsequently, the concrete shall be durable and free from crazing, thermal cracks and drying shrinkage cracks. The slump shall be kept to the minimum compatible with approved placing and compacting requirements, but in no case shall the concrete be placed at a slump of more than 100mm or less than 40mm, determined in accordance with IS: 516-1959. The recommended slump values are provided in Table below. Recommended slump values. Types of work With vibrators Without

Thin sections such as slabs, beams, columns, simply reinforced.

25-40 mm 100-125 mm

Thin RCC sections or sections with congested steel 40-50 mm 125-150 mm Mixing of Concrete: Concrete shall be weight batched or volume batched and mixed in an approved mixing machine fitted with an approved water metering device. The weight or volumes of cement and each size of aggregate as indicated by the mechanisms employed shall be within a tolerance of +/-3% of the respective weights or volumes per batch agreed by the Project Manager. If weight batching is used, the weights of the fine and coarse aggregate shall be adjusted to allow for the free water contained in them. The water to be added to the mix shall then be reduced by the quantity of free water contained in the fine and coarse aggregates, which shall be determined by the Contractor by a method approved by the Project Manager immediately before mixing begins. Unless otherwise agreed by the Project Manager, concrete shall be mixed in a batch type mixer manufactured in accordance with IS: 1791-1968. Mixers which have been out of use more than 30 minutes shall be thoroughly cleaned before any fresh concrete is mixed in that machine. Mixing plant shall be thoroughly cleaned before changing from one type of mix to another or before changing from one manufacturer of cement to another.


Controls shall be provided to ensure that no additional water can be added during mixing except with the approval of the Project Manager. The entire batch shall be discharged before the mixer is reached. In no case shall the mixing time be less than 11/2 minutes for a single batch. A concrete slab with adequate drainage shall be provided as a working platform unless alternative arrangements are specially permitted by the Project Manager in writing. The Contractor shall provide 100% extra concrete mixer capacity when batching concrete. Volume and Hand Batching of Concrete. Volume batching of materials and mixing of concrete will be allowed only for quantities less that 1.5m2 per location or at the discretion of the Project Manager. Hand mixing of concrete will be done on a close-boarded platform. The materials will be turned over not less than three time dry, water will then be sprayed on through a hose and the materials again turned over not less than three times in a wet condition and worked together until a mixture of uniform consistency is obtained. For hand-mixed concrete the specified quantities of cement will be increased by 10 percent and not more than 0.5 cum will be mixed at one time. Any concrete mixed by hand will be paid for at the appropriate rates for the grade of concrete inserted in the bill of quantities and no claim will be allowed in respect of any extra cost of hand mixing by reason of the additional cement or otherwise. Distribution and Placing of Concrete: The Contractor shall notify the Project Manager in writing 24 hours before pouring concrete, stating the times of pouring, and shall not commence pouring operations without his written approval of excavations, formwork, reinforcement, arrangements for plant and materials on site, installation of accessories, etc. Any concrete placed before obtaining such approval shall be rejected. The formwork or area of deposition shall be cleaned as specified. Constructional plant and materials required, or which may be required, during the concreting work and for curing shall be on site and fully prepared before concreting commences. All accessories shall be installed and formwork for holes, chases etc, shall be provided as specified. Only after all these preparations and other relevant requirements have been completed, the Project Manager shall issue written approval to place concrete. Concrete shall be transported, placed and spread by approved means and in such a way as to prevent segregation. Concrete with a temperature above 32oC or below 5oC or with a slump less than 40mm or more than 100mm shall be rejected. Concrete not placed within 30 minutes of adding water to the mix or before starting its initial set shall be rejected. Concrete shall be transported and compacted into a dense impermeable mass without segregation or bleeding or cracking to ensure that when hard it is durable, uncracked and uncrazed. Except where otherwise agreed by the Project Manager, concrete shall be deposited in horizontal layers to compacted depth not exceeding 400mm. Concrete shall be deposited as near as possible to its final position to avoid re-handling. Unless otherwise agreed by the Project Manager, concrete shall not be dropped into place from a height exceeding 2 metres. When trunks or chutes are used they shall be kept clean and used in such a way as to avoid segregation. The Contractor shall not place concrete in standing or running water.


Concrete shall be deposited continuously. No concrete shall be placed against concrete which has hardened sufficiently to cause seams, planes of weakness or cold joint. If for unforeseen reasons it is necessary to stop concreting before completion of the pour then construction joints as specified shall be formed and further concreting shall be suspended for at least 24 hours unless otherwise approved in writing by the Project Manager. Cutting and chasing of hardened concrete shall not be permitted without the Project Manager's approval. The Contractor shall provide openings, mortices, chases, sleeves, etc. and fix bolts, anchors etc. in concrete as work proceeds and support embedded items against displacement. Items cast shall have all voids filled with readily removable materials to prevent concrete ingress. The Contractor shall clean and wet and then fill tie holes with patching mortar. When required by the Project Manager honeycombed and other defect concrete shall be cut back to sound concrete, with perpendicular or slightly under cut edges and shall be prepared in an approved manner. The Project Manager will reject any concrete which he considers to have been inadequately mixed or in which the ingredients have segregated or which is no longer capable of being effectively placed or compacted. All receptacles used for the transport and deposition of the concrete shall be kept clean and thoroughly washed out after stopping work and at the end of each shift. The Contractor shall obtain the Project Manager's permission before concreting in air shaded temperatures which exceed 30oC and shall take approved precautions to prevent early setting etc.(use admixtures, cool ingredients, continuously spray formwork with water, erect sunshades etc.) to ensure that the concrete temperature when placed does not exceed 32oC. The Contractor shall obtain the Project Manager's permission before concreting in air temperatures below 2oC and shall take approved precautions to ensure that the concrete temperature is not below 5oC. No concerting shall be carried out in heavy rain. Compaction: Concrete must be carefully and thoroughly compacted during placing to ensure that it completely surrounds the reinforcement, fills the formworks and excludes voids. All concrete shall be compacted by using internal vibrators. The size and type of vibrator must be approved by the Project Manager and they shall be used by operators experienced in their use. Concrete is to be vibrated for the minimum time necessary for thorough consolidation, and the Contractor shall ensure that excessive vibration, leading to segregation, is avoided. Care must be taken to ensure that the vibrator does not touch the reinforcement or formwork. Internal vibrators shall be of the immersion type with a frequency of not less than 3000 vibrations per minute, and sufficient amplitude to consolidate the concrete effectively. The Contractor shall provide at least 50% duplication of all vibration equipment as standby during any period of concreting. Vibrators shall not be used to move the concrete within the formwork. Curing: Freshly deposited concrete shall be protected from premature drying and excessively hot or cold temperatures and shall be maintained with minimal moisture loss at a relatively constant temperature for the proper hydration of the cement and hardening of the concrete. The materials and methods of curing shall be subject to approval. Concrete surfaces not in contact with forms, shall be cured by one of the following materials or methods. Ponding, continuous sprinkling, or absorptive mat or fabric kept continuously wet with water which complies with the requirements of "water for concrete and curing".


Polythene membrane shall be laid direct on to the concrete in unbroken sheets with substantial close fitted lap joints. Sheets shall be weighted with timbers to prevent dry winds blowing under the membrane. Spray applied curing membrane and curing compounds shall be of approved manufacture and type and be of the maximum retentivity type. Curing compounds used shall have reflective properties; they shall be applied in accordance with the recommendations of the manufacturer and are to be used with extreme caution on any surfaces against which additional concrete or other finishing materials are to be bonded and shall not adversely affect the concrete. Application of curing water should not affect the finished fresh concrete surface by the dilution of the top layer. Curing shall be continued for a period of at least 7 days when methods (a) and (b) above are used. Rapid drying at the end of the curing period shall be prevented. The Project Manager may instruct, in hot, dry weather that a combination of the above methods shall be used. Exposed horizontal surfaces of slabs in hot windy weather may require additional protection between the initial compaction and final finishing stages to ensure that the concrete is not exposed for more than twenty (20) minutes after placing. Formwork exposed to direct sunlight during the curing period shall be shaded. Steel forms heated by the sun and all wood forms in contact with the concrete during the curing period shall be kept wet. No forms should be removed during the curing period. The use of any of these methods of curing shall be subject to the requirement of the Project Manager for meeting a satisfactory curing result. Any method not giving satisfactory results shall be discontinued and another, to the preference of the Project Manager, shall be applied instead. Joints: Construction joints shall be formed in either horizontal or vertical planes and located in the works to suit working stresses. They shall be so located and the quantity of concrete placed at any one time shall be so limited in size and shape as to minimise shrinkage and temperature effects. All reinforcing steel shall be continued across construction joints except where shown on the drawings. The surface of the concrete at all joints shall be straight and shall be thoroughly cleaned with water and air under pressure, to expose aggregate. The cleaned surfaces shall be well set and a cement grout wash applied; laying shall commence before the grout has set.

G Plaster Work G1 Providing and laying 12 mm cement plaster with C ement mortar 1:4. Preparation of surface: The joints shall be raked out properly. Dust and loose mortar shall be brushed out. Efflorescence if any shall be removed by brushing and scraping. The surface shall then be thoroughly washed with water, cleaned and kept wet before plastering is commenced. In case of concrete surface, if a chemical retarder has been applied to the formwork, the surface shall be roughened by wire brushing and all the resulting dust and loose particles cleaned off and care shall be taken that none of the retarder is left on the surface. The joints of masonry shall be raked out properly so that the plaster is well keyed with the masonry. Mortar: The mortar of the specified mix described in the item shall be used. Scaffolding: For all exposed brickwork or tile work, double scaffolding having two sets of vertical supports shall be provided. The supports shall be sound and strong, tied together with horizontal pieces over which scaffolding planks shall be fixed. For all other masonry in building, single scaffolding shall be permitted. In such case, the inner end of the horizontal scaffolding pole shall rest in a hole provided only in the header course for the purpose. Only one header for each pole shall be left out. Such holes for scaffolding shall, however, not be allowed in pillars/columns less than one metre in width, or immediately near the skewbacks of arches. The holes left in masonry works for scaffolding purposes shall be filled and made good before plastering. Note: In case of special type of brickwork, scaffolding shall be got approved from Engineer. Application of Plaster: Ceiling plaster shall be completed before commencement of wall plaster. Plastering shall be started from the top and worked down towards the floor. All putlog holes shall be properly filled in advance of the plastering as the scaffolding is taken down. To ensure even thickness and true surface, plaster about 15x15 cm, shall be first applied, horizontally and vertically, at not more


than 2 metres intervals over the entire surface to serve as gauges. The surfaces of these gauged areas shall be truly in the plane of the finished plaster surface. The mortar shall then be laid on the wall, between the gauges with trowel. The mortar shall be applied in a uniform surface slightly more than the specified thickness. The surface shall be brought to a true surface, by working a wooden straight edge reaching across the gauges, with small upward and sideways movements at a time. Finally the surface shall be finished off true with trowel or wooden float accordingly as a smooth or a sandy granular texture is required. Excessive trowelling or over working the float shall be avoided. All corners, arises, angles and junctions shall be truly vertical or horizontal as the case may be and shall be carefully finished. Rounding or chamfering corners, junctions etc. where required shall be done without any extra payment. Such rounding or chamfering shall be carried out with proper templates to the sizes required. In suspending work at the end of the day, the plaster shall be left, cut clean to line both horizontally and vertically, when recommencing the plastering, the edge of the old work shall be scraped cleaned and wetted with lime putty or cement grout before plaster is applied to the adjacent areas, to enable the two to properly 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 corners or arises. It shall not be closed on the body of the features such as plasters, bands and copings, as these invariable lead to leakages. No portion of the surface shall be left out initially to be patched up later on. The plastering and finishing shall be completed within half an hour of adding water to the dry mortar. Finish: The plaster shall be finished to a true and plumb surface and to the proper degree of smoothness as required. The work shall be tested frequently as the work proceeds with a true straight edge not less than 2.5m.long and with plumb bobs. All horizontal lines and surfaces shall be tested with a level and all jambs and corners with a plumb bob as the work proceeds. Precaution: Any cracks which appear in the surface and all portions, which sound hollow when tapped, or are found to be soft or otherwise defective, shall be cut out in rectangular shape and redone as directed by the Engineer. Thickness: The thickness of the plaster specified shall be measured exclusive of the thickness of key. The average thickness of the plaster shall not be less than the specified thickness and the minimum thickness over any portion of the surface shall not be less than specified thickness by more than 3 mm. Where the thickness required as per description of the item is 20 mm the average thickness of the plaster shall not be less than 20 mm whether the wall treated is of brick or stone. In the case of the brickwork, the minimum thickness over any portion of the surface shall not be less than 15 mm while in the case of stonework the minimum thickness over the bushings shall be not less than 12 mm. Curing: Curing shall be started as soon as the plaster has hardened sufficiently not to be damaged when watered. The plaster shall be kept wet for a period of atleast 7 days. During this period, it shall be suitably protected from al damages at the contractor’s expense by such means as the Engineer may approve. The dates on which the plastering is done shall be legibly marked on the various sections plastered so that curing for the specified period thereafter can be watched. Measurement: Length and breadth shall be measured correct to 10 mm and its area shall be calculated in square metres correct to two places of decimal. Thickness of the plaster shall be exclusive of the thickness of the key i.e. grooves, or open joints in brick works. The measurements of wall plaster shall be taken between the walls or partitions (the dimensions before plastering shall be taken) for the length, and from the top of the floor or skirting to the ceiling for the height. Depth of coves or cornices if any shall be deducted. The following shall be measured separately from wall plaster: (a) Plaster bands 30 cm wide and under. (b) Cornices, beadings and architraves moulded wholly in plaster. (c) Circular work not exceeding 6 m in radius.


Plaster over masonry pilasters will be measured and paid for as plaster only. A coefficient of 1.63 shall be adopted for the measurement of one side plastering on honeycomb work. Moulded cornices and coves: (a) Length shall be measured at the centre of the girth. (b) Moulded cornices and coves shall be given in square metres the area being arrived at by multiplying length by the girth. (c) Flat or weather-top cornices when exceeding 15 cm in width shall not be included in the girth but measured with the General Plaster work. d) Cornices, which are curved in their length, shall be measured separately. Exterior plastering at height greater than 10m from average ground level shall be measured separately in each storey height. Patch plastering(in repairs) shall be measured as plastering new work, where the patch exceeds 2.5 sq.m., extra payment being made for preparing old wall, such as dismantling old plaster, raking out the joints and cleaning the surface. Where the patch does not exceed 2.5sq.m in area, it shall be measured under the appropriate item under sub-head “Repairs to Building”. Deduction in measurements for openings etc. will be regulated as follows: (a) No deduction will be made for openings or ends of joists, beams, posts, girders, steps, etc. upto 0.5 sq.m. in area; no additions shall be made either, for jambs, soffits and sills of such openings. The above procedure will apply to both faces of wall. (b) Deduction for openings exceeding 0.5 sq.m. but not exceeding 3 sq.m. each shall be made for reveals, jambs, soffits, sills etc. of these openings When both faces of walls are plastered with same plaster, deductions shall be made for one face only. When two faces of walls are plastered with different types of plaster or if one face is plastered and other is pointed, or one face is plastered and the other is un-plastered, deduction shall be made from the plaster or pointing on the side of the frame for the doors, windows etc. on which width reveal is less than that on the other side but no deduction shall be made on the other side. Where width of reveals on both faces of wall are equal, deduction of 50% of area of opening on each face shall be made from area of plaster and/or pointing as the case may be. For opening having door frame equal to or projecting beyond thickness of wall full deduction for opening shall be made from each plastered face of wall. (c) For opening exceeding 3 sq.m. in area, deduction will be made in the measurement for the full opening of the wall treatment on both faces, while at the same time, jambs, sill and soffits will be measured for payment. In measuring jambs, sills and soffits deduction shall not be made for the area in contact with the frame of doors, windows etc. Rate: The rate shall include the cost of the labour and materials involved in all the operations described above. H Construction of drainage works H1 Providing and laying 900-1200 mm NP2 class RC pi pes, including collars, jointing in cement mortar 1:2 including visual inspection of jo ints etc. including excavation, supply and placing of gravel bedding and suitable trench backf ill as per the specification and drawings. The quantities and unit rates for the provision and laying of Hume pipes specified in the Bill of Quantities are for culverts under the road embankment as well as for provision of drainage of spoil disposal sites, as per design and instructions of the Project Manager.


Excavation: The ground shall be excavated to the lines and depths shown on the Drawings or to such other lines and depths as the Project Manager may direct. Trenches shall be of sufficient width to enable the pipes to be properly laid, jointed and haunched. Should the Contractor desire to use mechanical plant for excavating trenches or for laying pipes he shall submit his proposals for approval by the Project Manager, but such approval will not relieve the Contractor from responsibility for damage to pipes. Water in Pipe Excavations: Trenches shall be kept free from water, until, in the opinion of the Project Manager, the works will not suffer any deleterious effect from water. The Contractor shall, at his own expense, construct any sumps or temporary drains that the Project Manager may consider necessary. The Contractor shall make good at his own expense, any damage caused by prolonged and excessive pumping, and shall take all precautions necessary for the safety of adjoining structures and buildings by shoring or otherwise, during the time the trenches are open. Laying of Concrete Pipes: The physical requirement of reinforced concrete light duty non-pressure pipe class NP2 shall meet be as in the following table. Concrete pipes shall comply with the requirements of IS 458-1971. The pipes shall be laid true to line and level, commencing at the outfall, each pipe being separately boned between sight rails. Laying of pipes shall proceed upgrade of a slope. Before placing the pipe culverts, the bottom width of the excavation shall be covered with a drainage layer of stones of specification and depth as noted on the contract drawings. Where the required pipe length (as determined by the carriageway width, shoulder width etc) is not a multiple of the standard pipe size, then the contractor shall not be paid for any additional length of pipe that he installs. In the event that the pipe is installed over the design length which results in the need for scour or other water protection measures deemed necessary by the Project Manager, then these shall be provided at the contractor’s own cost.

900 50 19 50 200 1200 65 19 65 200 Loading, transporting and unloading of concrete pipes shall be done with care. Handling shall be such as to avoid impact. Gradual unloading by inclined plane or by chain block is recommended. All pipe sections and connections shall be inspected carefully before being laid. Broken or defective pipes or connections shall not be used. Pipes shall be lowered into the trenches carefully. Mechanical appliances may be used. In case where the foundation conditions are unusual such as in the proximity of trees or holes, under existing or proposed tracks, manholes etc. the pipe shall be encased all round in compacted sand or gravel for it’s full length. In case where the natural foundation is inadequate the pipes shall be laid either in concrete cradle supported on proper foundations or on any other suitable designed structure. If concrete cradle bedding is used, the depth of concrete below the bottom of the pipe shall be at least 1/4th of the internal diameter of pipe subject to the minimum of 10 cm and a maximum 30 cm. The concrete shall extend up the side of the pipe at least to a distance of 1/4th of the outside diameter of the pipe. The pipe shall be laid in this concrete bedding before the concrete has set. Pipes laid in trenches in earth shall be bedded evenly and firmly in compacted sand or gravel at least to a distance of 1/3rd of the outside diameter of the pipe. Necessary provision shall be made for joints wherever required.


When the pipe is laid in a trench in rock hard clay, shale or other hard materials the space below the pipe shall be excavated and replaced with an equalising bed of concrete, sand, gravel or compacted earth. In no place shall pipe be laid directly on such hard materials. When the pipes are laid completely above the ground, the foundations shall be made even and sufficiently compacted to support the pipeline without any materials settlement. Alternatively the pipe line shall be supported on rigid foundations at intervals. Suitable arrangements shall be made to retain the pipe line in the proper alignment, such as by shaping the top of the supports to fit the lower part of the pipe. The distance between the supports shall by a max of 2.5m centres, and not more than 300mm either side of any joints. In no case shall the joint come in the centre of the span. Care shall be taken to see that superimposed loads greater than the total load equivalent to the weight of the pipe when running full shall not be permitted. Where joints are to be made with loose collars, the collars shall be slipped on before the next pipe is laid. Adequate and proper expansion joints shall be provided where directed. Special care shall be taken to see that any excess of cement mortar is neatly cleaned off while each joint is being made and any earth, cement or other material thoroughly cleansed out of the pipes. A properly fitted plug shall be well secured at the ends of each pipe already laid and shall be removed only when the next pipe is being laid or on completion of the culvert or pipe line. The excavations shall be kept free from water until the joints are thoroughly set. Jointing of Concrete Pipes: Joints are generally of rigid type. Where specified flexible type joints may also be provided. Cement mortar for jointing pipes shall consist of 1 (cement):2 (sand) by volume.

Cement mortar shall be made in suitable small quantities only as and when required, and any motor, which has begun to set, or which has been mixed for a period of more than one hour shall be rejected. Rigid Collar Joint: This is a rigid joint. The two adjoining pipes shall be butted against each other and adjusted in correct positions. The collar shall then be slipped over the joint, covering equally both the pipes. The annular space shall be filled with stiff mixture of cement mortar 1 (cement):2 (sand) by volume), which shall be rammed with caulking tool. After day’s work any extraneous materials shall be removed from the inside of the pipe and the newly made joint shall be cured. Semi Flexible Collar Joint: This is made up of a loose collar, which covers two specially shaped pipe ends. Each end shall be fitted with a rubber ring which when compressed between the spigot and the collar, seal the joint. Stiff mixture of cement mortar 1 (cement):2 (sand) shall then be filled into the remaining work, any extraneous materials shall be removed from the inside of the pipe and the newly made joints shall be cured. Socket and spigot joint: The spigot of each pipe shall be placed home in the socket of the one previously laid, and the pipe then adjusted and fixed in the correct position with the spigot of the pipe accurately centred in the socket. A ring of gaskin or tarred rope yarn shall be inserted in the socket of each pipe previously laid and driven home with a wood caulking tool and wooden mallet; such yarn when in position shall not occupy more than one quarter of the total depth of the socket. The socket shall then be completely filled with cement mortar 1 (cement):2 (sand) and a fillet shall be bevelled off and extend for a length not less than 50 mm from the face of the socket. The newly made cement fillet shall be protected by means of a cover of damp hessian, which shall be kept moist for at least 24 hours after forming. Pipe to be Left Clean on Completion: On completion, all pipe lines shall be flushed from end to end with water and left clean and free from obstructions. Pipes Bedded and Haunched With Concrete: Where shown on the Drawings or directed by the Project Manager, pipes shall be bedded, surrounded and/or haunched with PCC M5:40. In carrying out this work the Contractor shall take care to pack the concrete under the around the pipes to ensure


even bedding and solidity in the concrete in no instance shall the concrete be thrown directly on the pipes. The upper surface of the concrete shall be struck off with a wooden screed and neatly finished off. Refilling Trenches: Backfill to depth of D/3mm of the pipe from it’s base shall be with filter material as provided in relevant sections under SQCA Specifications for Buildings & Road Works, 2009.

(where D is the nominal internal diameter of the pipe). Backfill for concrete pipes and minor drainage structures shall be obtained from the material excavated in forming the excavation and in the event of there being insufficient excavated material or the culvert is laid close to or above existing ground level then selected backfill shall be obtained from borrow pits. The remainder of the trench shall then be backfilled with best selected material available, placed in layers not exceeding 150 mm loose thickness, mixed, watered or dried as necessary and compacted. All backfilling material shall be compacted to a minimum dry density of 95% of MDD (Heavy Compaction). For pipe culverts which have been constructed close to, above or where the culverts protrudes above the existing ground the backfilling under the flanks and alongside and over the culverts shall be placed and compacted in layers not exceeding 150 mm after compaction to 95% MDD. The width of backfilling along the flanks of the Culvert shall be at least (2 + 1.5h) metres from each side of the culvert (Where ‘h’ is the height from the underside of the layer being compacted to the crown of the pipe in metres). All existing ground under this backfill shall be compacted to 95% MDD (Heavy Compaction) to a depth of 150 mm. The material used for filling alongside the culvert above existing ground shall be the same material as will be used for the adjacent fill and no additional payment will be made than that provided for the fill under relevant sections of SQCA Specifications for Buildings & Road Works, 2009. Backfilling shall be carried out simultaneously and equally on both sides of the culvert to avoid unequal lateral forces. In all cases there shall be cover of at least 600mm or D/2 mm over the crown of the culvert before construction equipment is driven over it unless other protective measures approved by the Project Manager have been provided. All works shall be completed prior to start of pavement layer works. Measurement: All measurement will be done in accordance with the specific item coverage for the works.

H5 Construction of chute as per specification and draw ing including excavation, filling and delivery of materials. Chutes are suitable for small streams only (width not more than 3 metres). They may be provided to transfer water between cross drainage structures which lie above one another due to zigs in the road, or to discharge water away from an outfall to a safe area. A series of parallel gabion steps are constructed across the stream bed and linked together with a gabion mat. Gabion mats/ Reno mattresses and steps are protected by a concrete layer of 50 mm thickness. Between two gabion steps, the length of the gabion mats should be 3 m and their gradient should not exceed 10%. For the construction of gabion steps and mats refer relevant sections under SQCA Specifications for Buildings & Road Works, 2009. I Pavement Layer Works Definitions The following definitions shall apply: Formation The level that is reached after excavation, at which the theoretical pavement construction shall commence. Typically this is 150mm below Finished Road Level, but may be lower to allow for placing of GSB. Subgrade The depth typically within 300 mm below formation level is designated as "subgrade". In the event that subgrade is unsuitable – i.e. has low CBR due to material content, moisture content etc, then it is to be removed locally until suitable material is reached. In the event that the depth to suitable material is high, typically >1.5m, then Subbase is to be placed prior to Base Course. Granular Subbase Granular Subbase (GSB) is a well graded granular material to be laid in layers not greater than 400mm and compacted to reach Formation Level. It is generally used where subgrade is weak (i.e. CBR<5). Base Course Base Course is a well graded granular material to be laid and compacted to achieve 150mm layer, and graded to provide running surface. Subgrade Consolidation The surface of the formation including shoulders shall first be cut to the proposed finished levels and grades. It shall then be cleaned of all foreign substances. Any ruts or soft yielding patches that appear due to improper drainage conditions, traffic hauling or from any other cause, shall be corrected and the sub grade dressed off parallel to the finished profile. The sub grade shall be consolidated in accordance with section 22.3.3 - Filling & Embankments, SQCA Specifications for Buildings & Road Works, 2009. The roller shall run over the subgrade till the soil is evenly and densely consolidated and behave as an elastic mass. The number of passes shall be dependent on the weight and type of equipment being used in accordance with section 22.3.3 - Filling & Embankments, SQCA Specifications for Buildings & Road Works, 2009. All the undulations


in the surface that developed due to rolling shall be made good with suitable material as the case may be and the sub grade is re rolled. This section deals with the treatment of the upper earthworks layers, including preparation of surface treatment of formation and the improvement of in-situ materials by selected materials. Preparation of Subgrade Preparation and surface treatment of formation shall be carried out only after completion of any specified drainage and unless otherwise agreed by the Project Manager immediately prior to laying the subbase or the base course where no subbase is required. I1 Preparation of subgrade with proper camber/ cro ss-fall by excavating earth to a depth of 300 mm, consolidation with road roller inc luding disposal of surplus earth up to 50m. Sub-grade of Loose Materials Loose materials remaining at the subgrade surface shall not contain particles larger than 60 mm. In addition the material shall have a CBR of not less than 5%, compacted to a dry density of 95% MDD of modified proctor density (heavy compaction). In-situ material in the subgrade in cutting that does not meet these requirements shall either be removed or if suitable placed in the embankment and replaced with material from cutting or borrow pits that meet the requirements for loose material in the subgrade. In fill areas, and in cuttings except otherwise instructed by the Project Manager according to the material encountered, loose materials of embankments and cuttings shall be deposited in layers of 150 mm compacted depths. Each layer shall extend over the full width of the embankments or cuttings and shall be compacted in accordance with the requirements specified hereunder:-

• The material shall be broken down to the specified grading and any oversize material which cannot be broken down to the required size shall be removed and disposed off. The material shall be scarified and the moisture content shall be adjusted by either uniformly mixing in water or drying out the material such that the moisture content during compaction is between95% and 100% of the Optimum Moisture Content. The moisture content shall be kept within these limits until compaction is completed except where otherwise instructed by the Project Manager. • Each layer shall be compacted to a dry density equal to at least 95% MDD of modified proctor density (heavy compaction).

Formations of Rock Cuttings The subgrade in rock cuttings shall be regulated after the trimming of the rock excavation by a regulating course of 150 mm minimum compacted depth of natural material complying with the requirements of natural material for subbase. The regulating course shall be laid and compacted in the same way as the subbase. Proofrolling All subgrade shall be proof rolled with a loaded scraper or truck with a minimum axle load of 8 tones. Proof rolling shall be satisfactorily completed before the layer is submitted to the Project Manager for approval and shall be carried out in his presence. All traces of deformation or depressions by the proof rolling shall be rectified. All proof rolling shall be at the Contractor’s expense. Surface Regularity and Tolerances The surface regularity and tolerances shall meet the following requirements:-


Surface Regularity 20 mm for the straight edge and ± 0.5 % for the crossfall When each layer is completed the Contractor shall request the Project Manager's approval and protect the layer. Measurement: The length and width of the completed work shall be measured correct to 10 mm and worked out in square metre area, correct to two places of decimal.

Brief descriptions of the types of conflict of inte rest Financial/Pecuniary interests Money does not need to change hands for an interest to be pecuniary/financial. People have a pecuniary/financial interest if they (or a relative or other close associate) own property, hold shares, have a position in a company bidding for government work, or receive benefits (such as concessions, discounts, gifts or hospitality) from a particular source. Or when there was actual exchange of cash in the form of loan or lending of money between the two parties. Close Personal Relationship: Close Personal Relationship should include anyone who is related through blood. Other Personal Relationship: Other personal relationship should include everyone who enjoys intimate relationship like family doctors, lawyers, and close friends. Enmity Conflict of Interest not only occurs in the form of good relations, it can equally or more seriously occur in the situation of enmity. Conflicts of interest can be actual, perceived or potential. • An actual or apparent conflict of interest involves a direct conflict between a public

official’s current duties and responsibilities and existing private interests. • A perceived or apparent conflict of interest can exist where it could be perceived,

or appears, that a public official’s private interests could improperly influence the performance of their duties – whether or not this is in fact the case.

• A potential conflict of interest arises where a public official has private interests that could conflict with their official duties in the future.
