Notes:-

1In good and excelent rock, the support requirement will be, in general, minimalbut will be dependent upon joint geometry, tunnel diameter, and relativeorientations of joints and tunnel.

2Lagging requirements will usually be zero in excellent and will range from up to25 percent in good rock to 100 percent in very poor rock.

3Mesh requirements usually will be zero in excellent rock and will range fromocassional mesh (or strip) in good rock to 100 percent mesh in very poorrock.

4B = tunnel width.

The major use of the RQD in modern tunnel design is as a major factor inthe Q or RMR rock mass classification systems.

The cost offurnishing, installing, maintaining and operation of the ventilation, lighting, mucking anddewatering system & arrangement for measuring the concentration of the poisonousgases shall be deemed to have been included in the unit rates tendered in the Scheduleof Rates for the underground excavation.

7.5 DRAINAGE AND PUMPING:

7.5.1 All water from the underground excavation shall be satisfactorily drained away andpumped out if necessary. In case, any underground springs are met with, the water fromthem shall be so led away as not to damage or endanger any work. The pumps to beused shall be operated either by compressed air or electric motor, and not by any type ofinternal combustion engine unless specifically permitted. Drainage of all tunnels, shaftsetc, excavated will be by gravity preferably. The cost of drainage by gravity duringconstruction will be considered included in the rate accepted for the various items in theSchedule of Rates for the underground excavation. If a channel has to be excavatedoutside the lines of excavations shown, the contractor may excavate such channel withthe approval of the Engineer-in-charge. This channel has to be filled back by thecontractor with concrete as specified for the back filling of tunnels. The excavation andback filling of such channel carried out by the contractor shall be at his cost. When,however, the water has to be pumped out, the contractor shall install the necessary



pumps and pipes as may be approved by the Engineer-in-charge in writing the cost forwhich will be paid separately through the items provided in schedule of works. Thechannels or the pumping unit shall be maintained satisfactorily till 21 days after concreteback fill is laid.

7.5.2 The underground and the water emanating from the construction sites required to bepumped out may be contaminated with dust, cement, slurry, dirt, sand etc. The pumpingarrangements to be provided shall be suitable for such drainage work. It shall be seenthat at no location there is pooling of water, which has the potential to obstruct the work.The contractor must also take all precautions essential to prevent water from the openarea flowing into the tunnels so as to keep the work sites including the face of the tunnelfree from water during all seasons of the year.

7.6 EXCAVATION LINES AND RATES:

7.6.1 The tunnels, shafts, etc, shall be excavated to the lines and grades shown in thedrawings, or as directed by the Engineer-in-charge. The ‘Excavation Lines’ indicated onthe drawings are, minimum excavation lines, within which no unexcavated material ofany kind shall be allowed to remain, The ‘Payment Lines’ are the outside limits up towhich the contractor will be paid regardless of the fact whether the limits of actualexcavation fall inside or outside these lines except in the case of natural cleavages etc.in rock unless specifically provided herein below. Unless specifically mentionedotherwise the ‘Payment Lines’ will be taken normally or radially to the centerline as thecase may be 150mm beyond the ‘minimum’ excavation lines.

7.6.2 Any enlargement beyond the ‘Payment Line’ considered necessary by the contractor forthe convenience of his work may be done by him with the prior approval of the Engineer-in-charge. This shall be filled back with concrete of class similar to the backfill concrete.All works carried out for such enlargement including the backfill will be purely at thecontractor’s cost.

7.6.3 OVERBREAK:

Any excavation carried out or which takes place inadvertently beyond the ‘Payment Line’shall be deemed to be an ‘OVERBREAK’. In case cavity and chimney formation occurduring the pendency of the contract, they shall be deemed to be covered in this definitionof the ‘OVERBREAK’.

7.6.4 GEOLOGICAL OVER BREAK:

“GEOLOGICAL OVERBREAK” consists of that portion of the over break outside a lineparallel to and 300mm beyond the “Payment Line”, the occurrence of which, as per thedecision of Engineer-in-charge, is an unavoidable result of adverse geological conditionsdue to concealed joints, faults and other structural defects in rock and not due to lack ofreasonable care and skill in excavation on the part of the contractor. This definition of‘GEOLOGICAL OVERBREAK’ shall be applicable for the term “GEOLOGICALOVERBREAK” used elsewhere in this document.

7.6.5 Reporting of GEOLOGICAL OVER BREAK:

An occurrence report of ‘OVERBREAK’ extending outside a line parallel to and 300mmbeyond the “Payment Line” shall be prepared and forwarded by contractor immediatelyafter its occurrence to Engineer-in-charge so that Engineer-in-charge may evaluate thecause of such OVERBREAK and decide if such OVERBREAK shall be defined as“GEOLOGICAL OVERBREAK”.



7.7 MEASUREMENT & PAYMENT:

Except as otherwise provided herein, no OVERBREAK beyond “Payment Line” shall bemeasured for payment.

Measurement for payment of “GEOLOGICAL OVERBREAK” will be made of the volumeof rock removed between a line parallel to and 300mm beyond the ‘Payment Line” andthe actual excavated rock profile.

7.7.1 Payment for “GEOLOGICAL OVERBREAK” shall be made at 30% (Thirty percent) of thebasic rates for tunnel excavation.

7.7.2 When the excavation of tunnel is in progress, if directed by Engineer-in-charge,contractor shall backfill portions of “OVER BREAK” and “GEOLOGICAL OVER BREAK”as defined in para 17.7 and 17.8 by concrete of suitable quality as approved byEngineer-in-charge. Measurement and payment of such a backfill concrete shall beregulated in accordance with relevant provisions made under item of concrete.

7.7.3 Cavity and chimney formation, if occurred during execution of work, shall be dealt as perprovisions applicable to “OVER BREAK” and “GEOLOGICAL OVER BREAK” dependingupon which portion of cavity and chimney formation lies in areas of “OVER BREAK” andwhich portion lies in areas of “GEOLOGICAL OVER BREAK”.

7.7.4 The contractor shall use every precaution to avoid excavation beyond the payment linesmarked on the drawings. All drilling and blasting shall be carefully and skillfullyperformed so that the material beyond the required lines is not shattered. No blastingthat might damage the rock shall be permitted and any damage done in the rock byblasting shall be repaired by and at the expense of the contractor and in a mannersatisfactory to the Engineer-in-charge.

7.8 SUBSEQUENT INCREASSE OR REDUCTION IN DIMENSIONS: -

7.8.1

7.8.2

If during the progress of excavation of any particular element of the work it is required toincrease or reduce the cross – sectional dimensions of the excavations from thoseshown in the typical cross- sections on the drawings, the contractor shall on being sodirected by the Engineer-in-charge, excavate the further portion to such increased orreduced dimensions at the same unit rate as tendered for the particular work. TheEngineer-in-charge will establish fresh, minimum, excavation line and the ‘Payment Line’shall be 150mm beyond such fresh ‘minimum’ excavation line. The excavation alreadydone shall also be enlarged to the increased dimensions if so ordered by the Engineer-in-charge. The quantity measured under this item will be between the original PaymentLine and the new Payment Line, which will be fixed by Engineer-in-charge. The quantitypaid for GEOLOGICAL OVER BREAKS due to natural cleavages etc. will, however, beexcluded. This will not, however, apply to the excavation of soft layers of rock alreadyexcavated and intended to be plugged back with concrete. The payment covered underthis clause shall be governed by relevant item of Schedule of Rates.

All excavation shall be so done that the rock around the periphery of the excavated finalsection shall not be shattered, loosened or otherwise weakened. Large over-breaks willbe avoided by suitable means such as light charges, ream holes or similar measures.The cost of this measure shall be considered as included in the accepted rate ofexcavation. In a special location, where specifically indicated or ordered by the Engineer-in-charge in writing, the use of explosives shall be discontinued and the rock excavatedby line drilling, broaching, barring, chiseling, wedging etc., as may be approved anddirected by the Engineer-in-charge. The payment of such excavation will be made under



relevant item of Schedule of Rates and no separate rate is admissible for purpose ofcalculating the quantity to be paid thus the depth of excavation shall be taken as 300mm(three hundred millimeters) from minimum excavation line.

7.9 SCALING OF ROCK: -

After face is blasted, gases removed and the face ventilated, all loose, or loosened rockfrom the top and side shall be removed by approved methods to avoid danger toworkmen and equipment. Later, if any loose or loosened rock is noticed anywhere in theexcavation, it shall be removed expeditiously. As the excavation advances trimming ofrock surface remaining within the excavations lines shall be undertaken simultaneously.In no case shall trimming be postponed and left to be tackled last. This work if left to bedone later takes lot of time and may involve avoidable delay resulting in postponementof completion dates. The cost of such scaling and removal of loose or loosened rock,trimming etc., shall be considered as included in the unit rate for excavation.

7.10 ADITS AND SHAFTS: -

If for adhering to the prescribed time schedule, additional faces are to be opened andadits are found necessary, the contractor may arrange to execute the work accordinglyafter obtaining the written approval of Engineer. In such cases the basic rate forexcavation for adit as also the tunnel excavation carried out through the adit will be thesame.

If provision of a vertical shaft is found necessary, the basic rate admissible for tunnelexcavation will be enhanced as under:

i For tunnel excavation involved in sinking thevertical or near vertical shaft.

50% Extra over basic rate ofexcavation in tunnel

ii For excavation of main tunnel through the shaft 0% (i.e. no enhancement)

7.11

7.11.1

TEMPORARY SUPPORTS: -

By temporary supports it is meant support whether of timber or steel required tosupport the underground excavated section during excavation but which can beremoved before or during the concrete lining. Contractor shall erect temporarysupports, when so desired by the Engineer-in-charge. It shall be the contractor’sresponsibility to bring in writing to the notice of the Engineer-in-charge location wherethe contractor may consider the provision of temporary supports necessary.Consequence, if any for his failure to do so in good time, shall be the soleresponsibility of the contractor.

The methods, the extent of supporting, sizes and spacing of supports etc., shall beapproved by the Engineer-in-charge.

7.11.2 The supports may be of steel or timber and shall be removed before placing theconcrete lining. No payment whatsoever will be made for temporary supports and thisitem is to be catered for in the rates quoted. If, however, some steel supports areallowed to be left embedded in concrete, they will be paid at the rate applicable forpermanent supports instead of temporary supports. Such supports shall not, however,be left in place unless on specific direction of the Engineer-in charge in writing. Incase temporary supports of timber and other materials except steel is allowed to be leftembedded in concrete, neither extra payment on that account for the same ordeduction in volume of concrete on that account shall be made.

7.14.4 No painting of any sort is to be carried out on the steel support.

7.14.5 ERECTION OF SUPPORTS: The section and spacing to which supports shallgenerally be erected is shown in approved drawing. Actual section and spacing atwhich arch ribs and posts are to be erected will be decided by the Engineer as thework is in progress to suit ground conditions. The decision of the Engineer-in-chargewill be final and binding on the contractor.

7.14.6 When the break out is affected in two portions as aforesaid the wall plate on bothsides shall first be erected correct to line and level and secured in position on timberpacking. The length of wall plates will depend upon the “SAFE BRIDGE ACTIONPERIOD OF THE ROCK” i.e. the time that can be allowed to elapse after blasting andbefore the steel support are erected, the cycle of operations and the advance to beobtained in one cycle. Wall plates laid on either side shall be connected loose to thepreviously laid wall plates by means of gusset plates and bolts. Arch rib shall then beguyed up and lined and leveled & connected to the previously erected arch rib bymeans of the tie rods and nuts at both ends.

7.14.7 In case of “OVER BREAK” that are judged as due to defective workmanship of thecontractor, no payment will be made for any new steel work erected by the contractorfor rectification of the damaged supports and no compensation will be paid on thisaccount. Any extra steel required for rectification / replacement of damagedpermanent supports shall be arranged by the Contractor at his own cost.

7.14.8 Any protective measure required for preventing / damage to support already carriedout should be done by the contractor at his cost or the work has to be carried withcontrolled blasting in order to avoid such damages. The contractor will not be entitled



for any compensation on this account.

7.14.8 Repair / Replacement of the support if necessary due to negligence on the part of thecontractor will be done entirely at the cost of the contractor. Nothing contained in thispara shall prevent the contractor from erecting, at his own expenses permanentsupports heavier than approved by the Engineer-in-charge, nor shall it be construed torelieve the contractor from the sole responsibility for the safety of the excavation or theliability for injuries of deaths of persons or damage to property.

7.14.9 The materials, bolts, nuts and washer will conform to the relevant IS specification forthe intended use and shall be arranged and provided by contractor at his own cost.The sequence and method of excavation shall be selected so as to enable theinstallation, of the necessary supports, before the BRIDGE ACTION PERIOD for theexcavated profile has expired. The quantity for this substantially depends upon thestrata encountered during the excavation. The contractor will not be entitled for anyclaim for such variations. The tentative spacing and number of support are shown inthe approved drawing. The detailed plan will be supplied to the contractor from time totime for different types of rock encountered and contractor will be required to providethe support as per these drawings.

7.14.10 The steel support shall be installed with proper workmanship, true to the line andgrade and as directed by the Engineer-in-charge and shall be maintained by thecontractor in proper condition and alignment until the concrete lining is placed againstthem.

7.14.12 In supported sections of the tunnel, the contractor shall securely brace the supportwith spreader, blocking and wedges as per approved drawing or as directed byEngineer at site

Where it is7.14.13 Due to insufficient or improper support in certain rock condition the load and side

pressures may increase due to gradual subsidence of rock and if support initiallyprovided are found inadequate substantially due to such increase in load it shall be theresponsibility of the contractor to take appropriate and prompt measures to strengthenthe supports and package material (cement concrete block, stone boulder etc.) behindthe support and grout the back packing material later after the lining has been placedor any other measures as approved by the Engineer-in-charge . The additional steelprovided by way of strengthening shall be measured for payment as a steel supportagainst relevant item of schedule rates and quantities. The back packing materialsshall form part of the first stage concrete of lining and therefore, will not be paid forseparately.

7.15 CEMENT CONCRETE: -

7.15.1 The work covered by this section consists of furnishing all materials equipment andlabour for the manufacture, transport, placing finishing and curing of concrete in theportal structures, lagging and back fill concrete behind R.C.C. lagging and forconstruction of mass CC / RCC work in construction tunnels and shafts. The item ofconcrete is split up into several items according to the class of concrete to be usedand its location and will be measured and paid for accordingly.

7.15.2 All concrete works whether Plain or RCC should conform to IS 456 - 2000 and the



relevant India Standards Specifications as directed by the Engineer. Payment ofCEMENT CONCRETE and RCC will be made under relevant schedule of items, ratesand quantities.

7.15.3 All concrete shall be mixed in an approved concrete mixing machine and such cementconcrete should be vibrated by use of mechanical vibrator and nothing extra over anabove the quoted rates for mass concrete will be payable for these operation unlessmentioned specifically.

7.15.4 The contractor will have to arrange the material required for providing weep holes orother drainage holes at his cost. The cost should include supplying and fixing of 75mm AC or PVC pipes as per approved drawings. No deduction of volume of weepholes / drainage holes for the purpose of calculations of volume of concrete payableshall be done.

7.15.5 Butt joints are to be provided at places at the direction of the Engineer. 12mm thickmud plaster will be done on one of the surfaces of the concrete. No extra payment forthis plaster or any deduction in the quantities of concrete will be made and the ratesfor mass cement concrete will be inclusive of this plaster.

7.15.6 Welding of reinforcement will not generally be permitted except in specialcircumstances under the written approval of the Engineer in accordance with therelevant I.S codes.

7.15.7 The exposed surface of mass cement concrete and RCC work shall be renderedsmooth and even. Nothing extra will be payable for rendering the exposed surfacesmooth, the cost of which will be considered as having been included in the ratesquoted for mass CC/RCC items.

7.15.8 PROPORTIONING OF CONCRETE: -

The exact proportions in which the different ingredients are to be used for differentparts of the work shall be as per mix design as approved by the Engineer-in-charge.

7.15.9 BATCHING AND MIXING EQUIPMENT: -

All aggregates shall be batched by weight. The contractor shall have to installbatching plant of the requisite capacity to maintain the required progress on differentitems of work. The batching plant shall be capable of determining accurately by directweighing the prescribed amounts of the various ingredients including water, cement,admixtures etc. and each individual size aggregate entering the concrete andcombining them to give them a uniform mix within the prescribed time and dischargingthe mix without segregation. The equipment and its operation shall at all the times aresubject to the approval of the Engineer-in-charge.

7.15.10 HANDLING: -

The measured materials leaving the batches must be properly and carefully handledso that batches reaching the mixers will be as uniform and complete as and whenreleased by the measuring equipment. This is particularly important when dry batchesare transported by truck or otherwise to portable mixers near the work. The handlingequipment shall be subject to the approval of the Engineer-in-charge. Loss ofmaterials during transferring batches from truck to mixer should be avoided so alsoincomplete discharge from trucks resulting in deficiency in that batch and loss ofcement due to dusting and scattering.



7.15.11 MIXING: -

All concrete shall be thoroughly mixed in the batching plant in a tilt batch mixer ofapproved type, size and design so as to positively ensure uniform distribution of thecomponents throughout the mass during the mixing operations. In no case shall themixing be done for less than two minutes. Each mixer and its operation shall besubjected to the approval of the Engineer-in-charge and if, at any time, producesunsatisfactory results, the same shall be promptly repaired or replaced to thesatisfaction of the Engineer-in-charge.

Each mixer shall be equipped by the contractor with a mechanically operated timingand signalling (or looking), device, satisfactory to the Engineer-in-charge for indicatingand measuring the completion of the required mixing period. Arrangement shall alsobe made to the check revolutions of the mixer. Dust and other undesirablesubstances shall be completely excluded. The mixers shall not ordinarily be loadedbeyond their rated capacity or operated in excess of the speed recommended by themanufacturer.

It is particularly important in charging the mixer that the ingredients (cement, sand andcoarse aggregate) shall be arranged in the charging hopper in such a manner thatproportional amounts of each will be in all parts of the stream as it flows into the mixerand that the period of flow of each is about the same.

The mixer should be capable of ready discharge of concrete of the lowest slump,which can be consolidated by vibration. Separation of coarse aggregate from mortar(which commonly results when the concrete is discharged from the moist mixers) shallbe avoided by proper arrangement of the discharge so that the concrete will fallvertically not diagonally into whatever container is to receive it.

The mixing plant shall be capable of being easily modified to add air entraining orother admixtures. If necessary each mixer shall be equipped with suitable means forindicating and recording concrete consistency. The sensitivity of the meter shall besuch that the effect of a change in steps of 25mm (one inch) shall be readilydiscernible. The consistency meters operating on the principles of measuring theelectrical input at the mixer motors shall not be acceptable.

7.15.12 CONVEYING :-

Concrete shall be conveyed from mixer to form as rapidly as practicable by methods,which will prevent segregation and/or loss of ingredients. In case such separationoccurs inadvertently, concrete shall be remixed before being laid in place. Thedistance between the mixer and the place of concreting as also mode of transport ofconcrete shall be subject to the prior approval of the Engineer-in-charge. It shall bedeposited in its final position as early as practicable but always within a period of 30minutes after mixing. When the initial set has taken place in a batch of concretebefore it is placed in position, such concrete shall be rejected and taken away from thesite to a distance and disposed off as ordered by the Engineer-in-charge. No claim inthis respect shall be entertained.

Methods of conveying concrete to any part of the structures wherein the concrete isloaded into chutes, belt conveyor or other similar equipment and carried in a thincontinuously exposed flow to the form will not be permitted except for very limited orisolated sections of the work and only when approved in writing by the Engineer-in-charge. The conveyance of concrete shall preferably be done by Agitator Cars/Transit



Mixer.

During hot or cold weather, concrete shall be transported in deep containers (the deepcontainers, on account of their lower ratio of area to mass reduce the ratio of loss ofwater by evaporation during hot weather and loss of heat in cold weather).

7.15.13 FORM FOR CONCRETE: -

Forms to confine the concrete and shape it to the required lines shall be usedwherever necessary. All exposed concrete surface having slopes 1 to 1 or steeper,shall be formed unless otherwise directed where the character of the natural materialcut in, to receive concrete is such that it can be trimmed to the prescribed lines, theuse of forms will not be required.

The forms shall have sufficient strength and rigidity to hold the concrete and towithstand the necessary pressure ramming and vibration without deflection from theprescribed lines. In all cases formwork shall be approved by the Engineer-in-chargebefore the concrete is poured but the contractor shall at all times be solely responsiblefor its sufficiency, strength and stability. The surface of all forms in contact with theconcrete shall be clean, rigid, tight and smooth.

Suitable devices shall be used to hold corners, adjacent ends, and edges of panels orother forms together in accurate alignment. The forms and their joints should be tightenough to obviate any danger of loss of mortar, which may result in honey combing, orloss of water that may cause the streaking.

Immediately before any concreting is commenced, all forms shall be carefullyexamined to see that all wood, shavings, sand dust and other refuge have beenremoved by brushing or by washing with a hose, and all traps and temporary doorsare made good.

7.15.14 MATERIALS: -

Forms shall be of wood, steel or other approved material except that the sheeting forall exposed surfaces where lining is not specified shall unless otherwise permitted ordirected be of tongue and groove lumber of uniform width unless otherwise specificallyauthorised. Forms of like character shall be used for similar exposed surfaces in orderto produce a uniform appearance. The type, size, shape, quality and strength of allmaterials from which forms are made and design of the forms shall be the soleresponsibility of the contractor but subject to the approval of the Engineer-in-charge.

In general, forms for permanently exposed surfaces shall consist of or shall be linedwith matched or dressed edge grain lumber of appropriate thickness free from loose orcracked knot.

Where lumber forms are used, the laying shall be in the direction, which will blendarchitecturally into the lines of the structures as decided by the Engineer-in-charge.

Metal forms or metal lined forms will be permitted for permanently exposed surfaceonly when an entire surface is to be built completely with such forms.

Curved and special forms shall be of a character that will result in smooth concretesurface. They shall be designed and constructed so that they will not warp or springup during erection or placing concrete.



Forms to be used more than once shall be maintained in a serviceable condition andshall be thoroughly cleaned and smoothened before being reused. When metalsheets are used for lining forms, the sheets shall be placed and maintained on theforms with the minimum amount of wrinkles, humps or other imperfection, the use ofsheet metal to cover imperfections in the lining of lumber faced forms for surfaces thatwill be permanently exposed to view shall not be permitted. Where plywood orhardboard is used for form lining, the joints between the sheets shall be smooth andas perfect as practicable and no patching of the plywood or hardboard would bepermitted for permanently exposed surfaces. Minor imperfection in the plywood maybe corrected by the use of plastic wood secured firmly in place and sand paperedsmooth.

7.15.15 TIES: -

The use of stay wires, metal rods or other similar devices embedded in the concretefor holding forms will be permitted if the ends of the rods are so arranged as couldsubsequently be removed to a depth of not less than 50 mm (two inches) from thesurface of the concrete without injury to the concrete provided that for walls to besubjected to water pressure on one side and to be water tight. The rods shall not becontinuous throughout the wall. Complete removal of the embedded rods will not bepermitted. Removal of embedded fasteners or the rods shall be such as to leaveholes of regular shapes for reaming. All holes left by removal of fastens from the endsof rods shall be immediately reamed with suitable toothed reamers so as to leave thesurface of the holes clean and rough and complete filled with dry patching mortar andthe surface finished to match the adjacent concrete. Wire ties will be permitted whenspecifically approved and shall be cut off flush with the surface of the concrete afterthe forms are removed. Wire ties shall not be used when permanently exposedfinished surfaces are required.

7.15.16 ERECTION AND REMOVAL: -

Shortly before placing concrete the surface of all form shall be oiled with a suitablenon-staining oil, not harmful to concrete, so as to prevent sticking of concrete andfacilitate removal of forms. Forms for unexposed surfaces may be thoroughly wettedin lieu of oiling, immediately before placing the concrete.

For use of wood forms, the oil should be capable of penetrating the wood andremaining sufficiently oily to eliminate sticking and of preventing absorption of waterand consequent warping. Almost any of the light colored and light oiled straightpetroleum oils, are acceptable for use on wood.

Compounded oils composed essentially of petroleum oils and other oils and animal orvegetable origin and gums or resin which are heavier in body and frequently darkerthan straight petroleum oils will be used in the case of steel lining forms. The oilsshould be applied by brush, spray or swab and the forms should be covered fully andevenly without excess of drip. Care should be taken to prevent oil from getting in thesurface of construction joints or on the reinforcing bars. Special care should be takento oil thoroughly the form strips for narrow groove seats, window doors and elsewhereso as to prevent swelling of the forms and consequent damage to concrete prior toremoval of forms.

Immediately before concrete is placed, precaution shall be taken to see that all formsare in proper alignment and that forms anchor and ties are thoroughly secure and



light. Where forms of continuous surfaces are placed in successive units, the formshall sit tightly over the surface so as to prevent leakage from the concrete and tomaintain accurate alignment of the surface.

The contractor shall strengthen or modify the formwork, when the Engineer-in-charge,considers it necessary and as directed by him. Forms should be left in place until theirremoval is authorised and shall be removed with care so as to avoid any injury to theconcrete. All forms shall be entirely removed from a pour to permit, inspection beforebeing reset for their next lift. Unless authorised, suitable mouldings shall be placed tolevel all exposed edges, at construction joints, and any other edges shown on thedrawings or as required by the Engineer-in-charge. The final detailed drawings willshow any formed recesses, slots, block outs and similar construction details, whichhave to be taken into account in fixing the form work cost of forming the recess shallbe deemed to have been included in the overall rate of the item.

The contractor shall take into account all the cost of formwork while quoting for therates of the concrete work items, and separate payment shall be due to the contractorfor the erection etc. of the formwork to the specification herein detailed.

7.15.17 PLACING CONCRETE: -

No mortar or concrete shall be placed except in the presence of the Engineer-in-charge or his duly authorized subordinate. Concrete shall be placed only in locationswhere authorized and no concrete or mortar shall be placed until the form work,installation of embedded parts, preparation or surface and necessary clean up havebeen done and checked and certified by the Engineer-in-charge or his authorisedrepresentative as being in conformity with specifications and drawings. Earthfoundations on which concrete is to be laid shall be firm, drained soil, free of any softmud or other objectionable and on which there is no standing or running water.

Rock surface or rigid masonry or concrete surface upon or against which concrete isto be placed shall be fresh, clean, solid and free from oil, mud, rock, loose, semidetached or unsound fragments, objectionable quoting and debris and sufficientlyrough to assure satisfactory bond with the concrete.

Immediately before placing concrete all such surfaces shall be thoroughly cleaned bythe use of high velocity air or water jets, sand blasting, steel brooms, picks or othereffective means satisfactory to the Engineer-in-charge.

All pools of water from the surface on which concrete is to be placed shall be cleanedto ensure proper bonding of fresh concrete with the rock surface. The method ofdisposal of water employed in working site shall be subject to the approval of theEngineer-in-charge. All concrete placing, equipment and methods be subject to theapproval of the Engineer-in-charge.

Continuous adequate telephone communication shall be provided by the contractorbetween the concrete mixing plant and placement location during the placement of allconcrete.

Sufficient mixing and placing capacity should be provided so that the work may bekept alive and free from cold joints. Formed concrete should be placed in thehorizontal layer not deeper than 0.30 m avoiding inclined layers and constructionjoints.

To get a monolithic placement, it is important that each layer be shallow enough sothat previous layer is still soft and the two layers be vibrated together. Concrete shall



not be allowed or caused to flow horizontally or on slope in the forms. Concreteplacing on slope should begin at the lower end of the slope and progress upward,thereby increasing compaction of concrete. Pneumatic placement of the concreteshall be avoided unless usual high velocity discharge is used to appoint where noseparation and scattering of the concrete occur.

The most important consideration of handling and placing concrete is that of avoidingseparation of coarse aggregate from the concrete. Obvious groups and clusters ofseparated coarse aggregates are objectionable. They should be removed before theconcrete is placed over them, otherwise they may cause serious imperfection in thefinished work. Hence, particular attention should be paid to the tendency forobjectionable separation to occur at the point of discharge so that uniformity andhomogeneity of concrete placement and good workmanship will be ensured.

Concrete shall not be dropped from excessive heights. The concrete shall dropvertically into the centre of whatever container receives it. To protect these rods,spacers and embedded features from damage and to prevent displacement ofreinforcement, concrete fall in forms should be confined in a suitable drop chute.

7.15.18 CONSTRUCTION JOINTS:

The position of construction joints shall be subject to the approval of the Engineer-in-charge. The concrete of the earlier pour shall be hacked to produce rough surface orgreen cut with air water jet after the concrete has hardened sufficiently (4 to 6 hoursafter vibration) as directed by the Engineer-in-charge. Before placing new concrete,the surface should be restored to the condition existing immediately, after hacking orgreen cutting by means of another washing with air water jet, vigorous brushing etc.

The contractor to the satisfaction of the Engineer-in-charge shall clean all the joints.All intersection of construction joints with concrete faces that will be exposed to viewshall be made straight, level and plumb. All exposed construction joints shall besubjected to the approval of the Engineer-in-charge. Surfaces of the constructionjoints of which have been permitted to dry by reason of the succeeding layer notplaced within the specified moist during period, shall be kept moist for at least 72hours prior to placing the succeeding layers.

When the work has to be resumed on a surface which has hardened, such surfacesshall be roughened and new concrete placed after taking all measures mentioned inthe para below:

Disturbance of surface concrete at the joint shall be avoided during the earlyhardening period. Before placing the succeeding layer, the surface of the concrete ofthe construction joints shall be thoroughly cleaned and loose defective or fracturedconcrete shall be removed satisfactorily.

7.15.19 WATER DISPOSAL: -

The method used for disposing of the water from washing the surfaces shall be suchas would not stain discolor or otherwise affect exposed surface.

7.15.20 DEPOSITION OF CONCRETE:

The method and equipment used for placing concrete shall be such as will permit thedelivery of concrete of the required consistency into the work without objectionabledelay, segregation, porosity or loss of workability.



All surfaces of forms and metal work including reinforcement bars that has becomeencrusted with dried mortar or grout from concrete previously placed, shall be cleanedof all such mortar or grout before the surrounding or adjacent concrete is placed.Concrete shall be deposited in continuous horizontal layers varying in thickness ofapproximately 300 mm (12”).

7.15.21 In reinforced concrete work the thickness of the layers shall be reduced to 150mm to300 mm (6” to 12”) or as directed. In congested parts care shall be taken to see thatall the bars are properly embedded and no voids are left. On flat, horizontal surfaces,however, the congestion of steel near the forms makes concrete placing difficult, amortar of the same cement and sand ratio as is used in the concrete shall be firstdeposited to cover the forms.

7.15.22 After the surfaces having been prepared to the satisfaction of the Engineer-in-charge,all approximately horizontal surfaces of rock and construction joints shall be cast withcement slurry of water cement ratio approximately of 0.60 by weight or less asspecified, it shall then be covered with layers of mortar approximately 50 mm (2”) to 75mm (3”) thick for rock surface and approximately 15mm thick for construction joints.The mortar shall have the same property of cement and sand and the water cementratio as the regular concrete mixtures unless otherwise prescribed by the Engineer- incharge. The consistency shall be suitable for placing and working in the mannerherein after specified. The mortar shall be spread uniformly and thoroughly with stiffbrooms into all irregularities of the surfaces. Concrete shall then be immediately laidupon the fresh mortar.

7.15.23 No concrete shall be placed in running water or during high winds, dust, storms,excessive heat and similar condition without prior approval of the Engineer-in–charge.The Engineer-in-charge shall further, have the right to disallow the placing of concreteduring such conditions and the contractor shall comply with such directions. No claimsshall lie against Railways on account of such action by the Engineer-in-charge in thisbehalf.

7.15.24 RATE OF PLACING: -

Concreting shall be continued without avoidable interruption until the structure ofsection is completed or until a satisfactory construction joint can be made. Concreteshall not be placed faster than the placing crew can compact it properly. In placing thinmembers and columns, precautions should be taken against rapid placement, whichmay result in movement or failure of the form due to excessive lateral pressure. Aninterval of at least 24 hours unless otherwise approved or directed by the Engineer-in-charge, should elapse between the completion of columns and walls and the placingof slabs, beams or girders supported by them.

The rate of deposition shall be such so as to have no objectionable effect onplacement of concrete, particularly near the forms and in and around embeddedequipment where the rate shall not exceed the limit placed by the Engineer-in-charge.

The contractor shall be entitled to no additional payments over the tendered rates byreasons of any such limitations on the placing of concrete.

7.15.25 CONSOLIDATION: -

i Consolidation of newly placed concrete shall ordinarily be done with internalvibrators. The equipment for vibrations should have adequate power and shall beof high frequency, rugged and reliable. Operators should be experienced,



competent dependable and energetic. Ample standby units and parts as well assystematic servicing should be provided. Vibrators should not be used to causeconcrete to move more than a short distance laterally, otherwise fine materialruns ahead and separates from the coarse aggregate.

ii Re-vibration shall be resorted to only after specific instructions are given by theEngineer-in-charge.

iii Where vibrations is used to full advantage of consolidation or newly placedconcrete, no supplementary roddings or other working of concrete is necessary.At corners, obstructions, block outs, locations with congested reinforcement,special care shall be taken to attend to these places with ample, properly appliedadditional vibration or rodding as the case may be.

iv Succeeding layers of concrete shall not be placed until the previously placedlayer is thoroughly compacted as lift, the coarse particles of the aggregate in thesurface shall be embedded while the concrete is being vibrated but the surfacesleft with the desired degree of roughness. Disturbance of the surface concrete atconstruction joint during early stages of hardening shall be avoided. Necessarytraffic on new concrete shall be on timber walkways constructed so as not tocause injury to the concrete.

v When smooth surfaces are required, for all surfaces, which will be permanentlyexposed to the weather, and for all surfaces next to embedded metal workaround which it is desired to prevent leakage, the adjacent concrete shall beproperly vibrated, spaded or tamped. For formed concrete surfaces to beexposed to high velocities of water, special precautions shall be taken to preventor to minimize surface pitting without resorting to cover manipulation of theconcrete.

7.15.26 REMOVAL OF DEFECTIVE CONCRETE: -

Concrete which is not placed and compacted in accordance with these specificationsand is found to have lower strength, density etc., than specified, as determined fromtest samples or core samples, shall be removed and replaced by the contractor at hiscost. The entire cost of removing and replacing such rejected concrete shall be borneby the contractor including the cost of all materials required in the replacement. Cost ofcement for rejected concrete shall be recovered from the contractor.

7.15.27 REMOVAL OF FORMS: -

The length of time that the forms should remain in place shall be as per relevant codalprovision or as decided by the Engineer-in-charge, with reference to weatherconditions, shape and position of the structure or structural members and the natureand amount of dead and live loads. The following minimum intervals of time shall,generally be allowed between placing concrete and stripping of forms but the periodshall be increased in case of wet weather and also at the option of the Engineer-in-charge.

For normal Portland cement: -

i Beams side walls, columns (unloaded) 3 daysii Slabs and arches (props left under) 4 daysiii Props to slabs and arches 10 daysiv Beams soffits (props left under) 8 days



v Props beams 21 daysvi Mass concrete 2 days

These minimum periods, are by experience known to be safe and no claims shall be entertainedagainst the project authority for damage caused owing to the periods not being sufficient. Thecontractor, may where he so desires, extend the above to longer intervals. This shall not, however,constitute any reason for any claim or extension of time.

If the contractor desires to remove the forms earlier than the period stated above by addition ofcement and/or suitable admixtures in the concrete, so as to gain early strength without affecting longterm strength, the question will be examined by the Engineer-in-charge in each case and hisdecision in the matter shall be final and binding. The cost of all such additions and admixtures shallbe on contractor’s account.

In no case should forms be removed until there is assurance that removal can be accomplishedwithout dipping, or defacing the concrete surface. Further more heavy live loads should not bepermitted until after the concrete has reached its design strength. The exact period shall be fixed bythe Engineer-in-charge and shall be binding on the contractor. The forms should be removed withgreat caution and without jarring the structure or throwing heavy forms upon the floor. In order toachieve this and wedges and clamps shall be used whenever practicable instead of nails.

In order to avoid excessive stress in the concrete that might result from dwelling of the forms, woodforms for wall openings shall be loosened as soon as this can be accomplished without damage tothe concrete. Forms for the openings shall be constructed so as to facilitate such loosening.

The contractor shall be solely responsible for any damage that may be caused by negligence,lack of proper precautions etc. in the matter of removal of forms and shall make the same good athis own cost to the satisfaction of the Engineer-in-charge.

7.15.28 REPAIR OF CONCRETE: -

Repairs of concrete shall be performed by skilled workmen and in the presence ofthe Engineer-in-charge or his responsible representative. The contractor shallcorrect all imperfection on the concrete surfaces as necessary to produce surfacesthat shall conform to the required standards. All materials procedures andoperations used in the repair of concrete shall be subject to approval by theEngineer-in-charge.

Surfaces of concrete finished against forms shall be smooth and free fromprojections. Immediately upon the removal of forms and within 24 hours thereof,wherever practicable, all unsightly re-digest or fins shall be removed and any localbulging on exposed surfaces shall be remedied by tooling and rubbing. All holes leftby the removal of fasteners from the tie rods, shall after being reamed with atoothed reamer, be neatly filled with dry patching mortar.

All honey-combed, porous, fractured or otherwise defective concrete and surfaceconcrete in which, in the opinion of the Engineer-in-charge additions, are required tobring it to the prescribed lines shall be removed by chipping concrete. The chippedopenings shall be sharp edge and keyed, and shall be filled to the required lineswith fresh concrete or as found suitable.

Where concrete is used for filling, so mentioned above, the defective concrete isremoved and good concrete exposed but in no case less than 100mm (4”) in depthand the concrete will be reinforced if and as directed by the Engineer-in-charge.Concrete filling shall also be used, for all holes passing entirely through concretesections.



Dry patching mortar shall consist of one part of cement to 2 parts of sand by volumeand just enough water so that the mortar as used will stick together on being moldedinto a bell by slight pressure of the hands and will not free water when so pressedbut will leave the hands damp. The mortar shall be fresh when placed, and anymortar that is not used within 30 minutes, after preparation shall be removed at thecontractor’s cost.

The mortar shall be placed in layers not more than 25mm (1”) thickness after beingcompacted and each layer shall be thoroughly tamped to the satisfaction of theEngineer-in-charge. Each layer except the last shall be roughened thoroughly toprovide an effective bond with the succeeding layers. The last of finishing layer shallbe smoothened to form a surface continuous with the surrounding concrete.Patching mortar shall be used for filling behind reinforcement for filling holes thatextend completely through a concrete section. Guniting shall be used for holes toowide for dry patch mortar filling and too shallow for concrete filling.

All patches shall be bonded thoroughly to the surface of the chipped openings andshall be sound and free from shrinkage cracks and trummy areas.

7.15.29 CURING AND PROTECTIONS: -

All concrete shall be protected against injury until final acceptance. Exposedfinished surfaces of concrete shall be protected from the direct rays of the sun for atleast 72 hours after placement. Fresh exposed concrete shall also be protected fromthe action of the rains flowing water and mechanical injury. No fire shall be permittedin direct contact with concrete at any time. Concrete in which Portland cement isused shall be kept continuously moist for not less than 14 days for normal concreteand 21 days for concrete containing pozzolonas by covering with water saturatedmaterials or a system of perforated pipes mechanical sprinklers or porous hose orby any other approved method. Curing period where special cement may be usedshall be specified by the Engineer-in-charge. Construction joints shall be cured inthe same way as the other concrete and shall also if practicable be kept moist for atleast 72 hours prior to the placing of additional concrete upon the joint. Horizontalsurfaces shall be cured by sprinkling water or by covering with damp sand or maybe cured by the use of wet quilts or mutts, which will satisfactorily supply therequired curing water. If damp sand or quilt is used fur curing, it shall later becompletely removed. The time of applying damp sand shall be specified by theEngineer-in-charge before which curing will be carried out by other approvedmethods.

The methods of keeping formed concrete surface moist shall be continuous,sprinkling or spraying of water as may necessary to prevent any portion of thesurface from drying the specified period.

The water and other methods of curing shall be so handled as not to stain concretesurfaces, which shall be exposed.

The actual methods of curing adopted shall be subject to the approval of theEngineer-in-charge. The contractor shall have on hand and ready to install beforeactual concrete placement is started, all equipment needed for adequate curing andprotection at all locations of concrete placement.

7.15.30 In limited areas and for special purposes the use of an approved and properly



applied compound may be permitted at the discretion of the Engineer-in-charge torestrict the evaporation of the mixing water. Such curing compound shall be of thesurface membrane type, which will thoroughly seal the surface. Curing compoundshall not be used on joints where bonding is required.

The curing compound shall be used as directed by the Engineer-in-charge. The costof curing compound and all operations involved in its use shall be on contractorsaccount.

7.15.31 Finished concrete surface shall be protected from stains and surfaces or edgeslikely to be injured during the construction period shall be kept properly protected byleading forms in place or erecting protective covering to the satisfaction of theEngineer-in-charge.

7.15.32 In case the curing operations are inadequate or unsatisfactory, the Engineer-in-charge shall be entitled to take such steps as he may deem necessary to makegood to deficiencies and defects at the contractor’s risk and cost.

7.15.33 DAMAGED OR DEFECTIVE CONCRETE: -

Concrete damaged from any cause and any concrete which shall be found defectiveby reason of the contractor’s operations at any time before the completion and finalacceptance of the work shall if and where he directed be removed and replaced bythe contractor with acceptable concrete as directed by the Engineer-in-charge andall the risk and cost of such operations including the cost of such removed concreteshall be borne by the contractor.

7.16.11 Sufficient concrete coverage as indicated in the drawings, should be provided toprotect reinforcement from corrosion. All protruding bars from concrete or masonryto which other bars are to be attached and which will be exposed to action of theweather for an indefinite period should be protected from rusting by a thin coat ofneat cement grout. Accurate record shall be kept at all the times of the number,size lengths and weights, of bars placed in position for different parts of the work.

7.16.12 PAYMENT: -

i) Before starting concreting, the contractor shall make certain that the measurementof the reinforcements placed in has been recorded and that the Engineer-in-chargehas certified to the correctness of reinforcement used. Failure to do so might meanno payment or payment (full or partial or Nil) at the discretion of the Engineer-in-charge for the reinforcement concerned.

ii) Unit weights to be used in determining weight of steel computed shall be as perstandard weight of the bar / section given in I.S Codes.

6.23.13 WELDING OF REINFORCEMENT BARS: -

i) Wherever the Engineer-in-charge shall so direct or wherever the contractorproposes to adopt welding for joints in reinforcement in place of lapping, thecontractor shall prepare at least three samples of butt welds as directed byEngineer-in-charge. These specimens shall be got tested in a recognizedlaboratory by the Engineer-in-charge. If the results are satisfactory the Engineer-in-charge may allow welding in place of lap joints. The decision of the Engineer-in-charge in this regard will be final and binding on the contractor. The joints shall bebutt-welded by electric arc method. The ends of the bars shall be cleaned of allloose scale, rust, grease or other foreign materials and all welding of reinforcementbars used in reinforced concrete construction or as directed by the engineer-in-charge.

ii) Weld will be considered unsatisfactory if it fails to sustain tensile stress of at least90% of the tensile strength of the bar in which the weld has been made. Thecontractor shall make all necessary arrangements at his cost for carrying out thetests as directed by the Engineer-in-charge.

iii) Anchors in rocks, wherever indicated on the drawings or directed by the Engineer-in-charge, holes shall be drilled into rock to receive anchors for anchoring to therock, concrete or masonry structures or parts, thereof. The type of dimensions of the
