Normally thematerial shouldnot contain boulders or stone large than 3/4th the size of thickness ofthe compactedlayer. When compacted the materials should be fairly pervious. Thepermeability of thecompacted casing zone determined by the methods deemed fit bythe Engineer-inchargeshould be about 100 feet per year or as specified by theEngineer-incharge.ED-B-4 Placing of Materials :General :The embankment shall be constructed to the lines and grades shown on thedrawings. Theslopes of the division lines between zones or portions of embankmentare tentative and shallbe subject to variation at any time prior to or duringconstruction and on account of this thecontractor shall be entitled to no additionalallowance above the unit prices accepted. Noroots vegetable matter, humus or otherunsuitable materials shall be placed in theembankment. The contractor shall maintainthe embankment in an approved manner until thefinal completion and acceptance ofall of the work under the contractor. Care shall be taken todrain all rain water failingon the rolled surface away beyond the dam toe lines. Theembankment for eachportion shall be maintained approximately level. But if it is necessary tohave slope,the slope should not be steeper than 1:20 (vertical to horizontal). All openings orgapsthrough the embankment required for construction purpose shall be subject toapprovaland such openings or gaps if approved shall be constructed so that theslope of the bondingsurface between embankment in place and embankment to theplaced is not steeper than 1:4(vertical to horizontal). The suitability of each part of thefoundation for placing embankmentmaterials thereon and of all the materials for usein embankment construction will bedetermined by the Engineer-in-charge. Thematerial shall be placed in lawyers andcompacted.

The contractor shall constructand maintain all reference pillars. Noextra payment is admissible to the contractor onthis account.Signature of contractor No of Corrections Executive Engineer

86Preparation of Foundation of preparation of Surface of Earth Work Previously Lands :a) General :No material shall placed in any section of the dam until the foundation for the sectionhasbeen dewatered and suitably prepared and has been approved by the Engineerincharge.Itis necessary to ensure the surface material of the foundation will beascompact and well bonded with the first layer of the embankment as hereinafterspecifiedfor subsequent layers of the earth fill. All portion of excavation made for testpits or trailand all other existing cavities found within the area to be covered by earthfill whichextend below the established lines of excavation for dam embankmentfoundation shallbe filled with compaction earth fill materials as herein specified forearth fill inembankment and payment therefore will be made as provided for hearingor casting zonein which section the pits or cavities are filled.b) Foundation other than rock :The seat of the dam is stripped, shall be cleared of all loose or objectionablematerialbefore placing any layer. The surface shall than be watered and rolled asdirected if thesurface material is not compact enough. The surface shall then bescarified by ploughingor by harrows or by rake or by any suitable method, all clodsbroken and then it shall bemoistened liberally but not more than 2% on wet side ofoptimum, unless the foundationmaterial already contains optimum amount ofmoisture before the first layer is placed.c) Rock Foundations :Any steps of larges depressions or humps caused by abrupt change in levels, shallbeevened out to 1:5 slope and the removal of rock will be paid under item ofexcavation. Ifnecessary the surface shall be roughened by the shallow longitudinaltrenches orcorrugations cut in the rock and the removal of rock will be paid under theitem ofexcavation. The rock surface including all pockets or depressions shall becarefullycleared of soil or rock fragments before placing of the first layer, dykes andseams of softmaterial shall be opened out, cleaned to the depth as directed and filledwith selectedimpervious material or lean concrete as directed by the Engineer-incharge.Thefoundation surface shall be moistened but no standing water shall bepermitted when thefirst layer is placed. The rock surface after moistening shall begiven a slurry wash andimmediately after the wash (so as not allowing it to dry) firstlayer of soil will be placed.If exposed surface is very rough and uneven, so as topreclude the use of poweroperated rollers and equipment. It shall be brought to aneven surface by filling thehollows and depressions in layers not more than 100 mm.thick with moist well stakedsoil, having moisture content equal to standard proctoroptimum + __________ of dryweight of soil and compacting the same by hand,pneumatic or mechanical tampers.d) Earth work previously laid :The treatment of the surface in this case before a fresh layer is placed will be thesameas for the foundation other than rock. Over compacted portions of embankmentformeddue to constant traffic which are likely to separate from the layers below shallbe entirelyremoved without any extra cost. When smooth rollers are used forcompaction, thesurface of a compacted layer shall be scarified or roughened beforefresh layer is laid onit. When sheepsfoot rollers are used for compaction, fresh layermay be directly laid onthe previously rolled surface. Water shall be sprinkled on theprevious layer unless thematerial in the surface is sufficiently wet. In case it containsmoisture more than O.M.C.due to rain, etc, it shall be allowed to dry to have optimum moisture and rolled again.Signature of contractor No of Corrections Executive Engineer

87e) Rock abutments or sides of rock cutting :If should be seen that no hollows side way are left, Also all projections shall betrimmed.Before placing embankment against rock abutments or sides or rock cuttingthe sameshall be trimmed to 1/2 : 1 slope, Preferably 1 : 1 slope and be thoroughlywashed withmud slurry and selected moist soil laid against the same until the mudwash is still wet.The moist soil laid against rock surface shall be compacted by handrammers or airoperated rammers. Soil with moisture content equal to O.M.C. 2% ofdryweight of soil will be used for this portion.f) The cost of operations involved in preparation of foundation surface shall beincluded inthe rates of embankment.Laying and spreading in layers :a) Approved material free from clods and lumps, larger than 50 mm. size shallbeconveyed directly from source of excavation or from stock piles and laid inappropriatezones of embankment as directed by the Engineer-in-charge, on surfaceof thefoundation or previously laid earth work prepared as specified.The materialshall then bespread on the embankment in uniform and continuous layersapproximately horizontalunless earth work in slope has permitted or specified.b) Thethickness of layers will depend on the nature of materials and the type ofcompactingmachinery. The thickness of a layer should be such that desired densityaftercompaction shall be uniformly obtained throughout the depth. For the guidanceof thecontractor it may be started that the thickness of the layer shall be 20 to 23cms. Looseand 15 cms. Compacted for sheep foot roller, 15 to 11 cms. loose and 11cms compactedfor smooth wheeled roller and 8 cms. loose and 5 cms compacted byhand pneumatic ormechanical tampers. The thickness of the compacted layers willbe found out by takinglevels after every three (or less number, if necessary) layerslaid and compacted andfinding out the average. The layers shall be spread in uniformwidth and in stages tofacilitate compaction by rollers. The work in various zones shallas far as possible beraise simultaneously. If, however, any zone or its part ispermitted by the Engineer-inchargeto be raised higher than the part adjacent to, it theloose uncompacted material atthe junction shall be removed or watered andcompacted to specified density withoutextra cost as directed by Engineer-in-charge.A minimum slope of 2:1 should be providedat such junctions & vertical differencebetween such two junctions should not be movethan 15 meters.c) No clods or lumps more than 5 cms. Size shall be allowed in hearing and all lumpandclods shall be broken upto the above size before rolling.d) The distribution and gradation, of materials throughout the impervious coreincluding thebackfill of the cut off trench shall be free from lenses or pockets ofmaterials differingsubstantially in texture or gradation from surrounding material. Theexcavation andplacing operations shall be such that the materials when compactedwill be so blended asto secure the best practicable degree of compaction,impermeability and stability.e) The Engineer-in-charge may designate the location in the earth fill where theindividualloads shall be deposited. The most impervious materials shall be placed inthe centralupstream portion of the earth fill and the more previous materials shall beplaced oneither side of it so that permeability of the fill will be gradually increasedtowards theupstream and downstream edges of the earth fill. When materials differ indry density buthave about the same permanently the material having the greaterdensity should beplaced in the outer sections of the zones of the dam as the casemay be.f) Should cobbles and rock fragments of size larger than permissible be found inotherwiseapproved earth fill material they shall be removed by the contractor either atthe side ofexcavation or after being transported to the earth fill but before thematerials in the earthfill are rolled and compacted.Signature of contractor No of Corrections Executive Engineer

88Such cobbles and rock fragments shall be placed in therock toe directly or wasted asapproved and directed by the Engineer-in-charge.g) In order that proper compaction can be done upto the edges of the designedsection, thesection shall be widened by half meter on each side i.e. on downstreamand upstreamside and extra material shall be deposited for this purpose at thesection. The wholesection will then be compacted and then dressed and brought tothe required slopes.Necessary extra quantity required to be handled for this purposeshall not be paid for andis considered to be included in the rate of this item.Moisture content :a) The water content of the earth fill material prior to and during compaction shallbedistributed uniformly throughout each layer of the material. The difference (Wo-W)whereWo is optimum moisture content, as determined by the standard proctorcompaction test,xpressed as percent of dry weight of soil and W is the moisturecontent of theembankment being compacted, expressed as percent of dry weight ofsoil shall be asfollowsi) (W – Wo) to be : - 2 % to + 2 % in case of at least 90% samplesin case heartingand 75% in case of casing, collected in a week.ii) (W-Wo) to be - 3 to + 3% in case of the remaining 10% & 25% samples. Thestandardproctor compaction tests will be made by the Department from time to time.The materialshall be brought to the proper water content by adding necessaryamount of water ofallowing moisture to evaporate either at the borrow pit or on thedam beforecommencing compaction of layers. When water is proposed to be addedat theembankment, the required amount of water to be sprinkled for given quantity ofsoil shallbe first calculated making due allowance for natural moisture content,evaporation, basewatering etc. This calculated quantity of water shall then bethoroughly mixed with soilby means of the disc harrows or any other suitable methodbefore compaction. Allcharges for watering and mixing are included in the item ofembankment includingpumping, transporting, pipe lines etc. as necessary.b) It may be necessary to allow the water to soak into the soil after sprinkling andmaking.If necessary for sufficient time to have uniform moisture throughout the layer.Thecontractor shall not get any extra payment for stoppage of work necessitated forallowingsoaking of the soil.c) Water content in soil to be laid to fill hollows in rock foundation and rock abutmentand near sides rocking cutting will be as specified under thespecifications for preparation of foundation (O.M.C. + 2 percent of dry weight of soil).The samemoisture content shall be adhered to in case of filling at the sides of C.O.T.filling andfilling around masonry structure.Compaction :a) Each layer after it is found to have specified moisture content uniformly distributed,shallbe compacted to give specified density. No fresh layer of soil shall be laid andcompactedunless previous layer is approved by the Engineer-in-charge. If the watercontent of thematerial spread in layer is more or less than specified, compaction shallnot be staredunless the moisture is brought to specified value.Signature of contractor No of Corrections Executive Engineer

89b) Compaction of the embankment shall be done by roller specified below except atpartswhich are not accessible to the above rolling equipment. Compaction ofcasing zone shallbe done by smooth wheeled power rollers (8 to 10 tons) or bystandard sheep foot rollers.Compaction of hearting zone and C.O.T. filling shallbe done by standard sheep footroller. The number of passes required by aparticular type of roller to attain specified density shall be decided by actual trialsfor different types of soils to be used & equalnumber of passes should be givento each layer before carrying out the field density test.The final control ofcompaction will, however, be on basis of specified densities and noton thenumber of passes.c) In the parts of dam inaccessible to the specified rolling equipment such as test pitsortrial pits below foundation level, Irregular sides of cut off trench and portionsaround & incontract with the structures where the rolling equipment will not bepermitted to operate,compaction shall be accomplished with either hand ormechanical tampers of approvedtype. Rulers will not be permitted to operate within0.5 meter of concrete or masonrystructures and the filling within this distance shallbe tamped by hand and mechanicaltempers. All material to be tamped shall bespread in layers with thickness as specified.The moisture content of the materialand the degree of compaction shall be equal to thatspecified separately. Specialcare as directed shall be exercised to obtain a goodcontract and good bond withrock surfaces, surfaces of masonry or concrete.d) Field density tests :The degree of compaction will be such as to give dry density as specified below.Thedensity measurements will be conducted by the department from time to time toascertainwhether the compaction attained in as specified. For this purpose off every300 cubicmeter of compacted earth work of one zone or for every layer compacted ofa particularzone at least two field density tests will be taken and the P.D.D. & P.M.C.worked out byover drying method or k-oil method if the correlation is found to existwith the former.Separate tests are to be taken for the various zones of the dam. Asthe over dryingmethod involves a 24 hours period to facilitate work preliminarycontrol as follows shall beexercised. The wet density of compacted layer shall beequal to or above optimum wetdensity (O.W.D.) & placement moisture content(tested by kerosene oil burning method)with + 1% of the permissible either additionalrolling will have to be done without anyextra cost or the layer may have to beremoved at no extra cost. In the event ofadditional, rolling being permitted, if it isfound that original moisture has evaporated, thelayer may be broken up or scarifiedas directed and watered and allowed to soak beforerolling to bring the moisturecontent to specified value.Necessary assistance for carryingout such density andmoisture samples for density measurements will be taken anywhere to ensure thatno weak spots, at location such as junction of sloping filter andhearting or castingturning places of compacting equipment or any doubtful area are left.Signature of contractor No of Corrections Executive Engineer

The admixture will be supplied by thedepartment free of cost.The contractor will not however be paid extra for adding suchadmixturesTheequipment for mixing and grouting shall be capable of effectively mixing the groutincorrect and specified proportions agitating it and it and pumping in to the holes incontinuousflow at the designed pressures. Satisfactory arrangements shall be madefor accuratelymeasuring the quantity of water, cement and other materials to beused. In general twomixing tanks concerned in random shall be used, the grout beingmixed in the first tank calledmixer and kept agitated to the proper consistency in thesecond called agitation tank prior tobeing pumped in to the holes. This latter tankshall feed the grout directly to the pump.The pump shall be of such design as toenable wide rage of pumping speeds to be used andto maintain a constant flow ofgrout intake in the hole at the designed pressure ( 2 kg / cm2)i.e. reciprocatingdouble acting air driven pump. The mixed grout shall be conveyed to thehole bymeans of a suitable pipe or flexible rubber hose designed to the withstandthemaximum pressure required and of internal diameter of not less than 1”. Thecirculatingsystem of returning extra grout to the mixer shall be adopted and the groutshall be keptcirculating continuously at sufficient velocity to prevent undue settlementor clogging at thefitting in the pipe line. Both the pump and pipe line shall be flushedoccasionally and thedeposits of grout in pump and mixer not removed by flushingshall be cleaned out by scrapingupon the completion of any continuous operation allpipes shall be dismantled and thoroughlycleaned.Pressure central valves shall beinstalled at the pumps, or in the injection system foradequate control of the operation.Specially equipped gauges with diaphragm or a short tubefilled with semifluid waterproof grease or oil, to prevent the entry of grout in to them shall beinstalled both atthe pumps and hole so that they will directly read both the hole pressure andpumpingpressure. The mixers and pump shall be placed as close to the hole aspracticableand long pipe line savoide, both in the interest of control and undesirableblockages. Allconnections both at the pumps and at the header into the hole, shall bewell titled and beconsistent with the minimum dia of 25 mm as specified above.Themixer shall be provide with a water meter to measure accurately the quantity ofwaterbeing used. A fine screen capable of being readily removed, cleaned andreplaced shall beprovided between the mixer and pump. Any arrangement ofequipment shall be flexible andcapable and modification on to meet constructionexigencies.Initially, grout shall be applied at specified pressures with thin mixes. Theactual proportion ofcement to water shall be decided upon site, depending upon thestrata met with and theresults of water intake test, but generally shall very between1:10 to 1-1 (Vol of dry cement :Vol of water). Depending upon certain characteristicswhich may reveal themselves in thecourse of injections, pumping speed may beincreased and mixes thickened tocommensurate with resistance to injections. Ifpressures remain relatively low, compared withthe final injection pressure of thestage concerned, despite such a procedure suitableadmixtures shall be added asdirected by the Engineer-in-charge to thicken the mix and thereby localize thetreatment for any particular injection point. Alternately intermitant groutingshall berestored to if directed to do so by the Engineer-in-charge is order to allow time forthegrout set and thus accelerate plugging of the same. As a hole approaches refusalthe groutshall be progressively thinned the pumping shall be carefully regulated andthe groutingcontinued to refusal at the specified maximum pressure and maintainedat this pressure forthe period of not less than 10 mins. If for any reason groutingoperations must be stoppedbefore a hole has been grouted to refusal, clear watershall be kept running into the hole unitgrouting is resumed. After the groutingoperations are completed for the shift or the day, theremaining unused grout mixshall be thrown away.Signature of contractor No of Corrections Executive Engineer

The sequenceof feeding of the ingredients into the mixer shallgenerally be as under.50% of requirement of water50% of the requirement of sandFull quantity of cementBalance quantity of sandBalance quantity of water.M-12 Mix variation :M-12.1 Variation clause for cement :If the proportion of cement to sand is varied for any reason including replacement ofcementby fly ash, surkhi or any admixture an addition or deduction, shall be made inthe rate ofmasonry at the rate of Rs. ________ per kg. of cement used in excess orshort of thestipulated requirement of cement per cubic meter of masonry. For thispurpose the volume ofmortar in masonry shall be taken as forty five percent (45)% ofvolume of masonry and thevolume of mortar will be taken to be a equal to the volumeof the sand before mixing. As permix variation clause if in case of the rates of cementto total aggregate is modified bychanging the cement content under specific orders ofthe Engineer-in-charge, the contractorshall be paid of incurred decreased rateaccording to the variation in the cost of cement. Thevariation in the cost of cementwill be calculated at the rate of cement specified in Scheduled‘A’ of theagreement.Generally the weight of cement bags is taken as 50 kg. for calculation butactually the weightof bags is found less. Thus this shortage of cement should becorrected by weight volumebatching and may be borne by the depth, if controlledconcrete quantity is to be achieved.
