EXCAVATION

2.0.0 EXCAVATION :

2.1.0 SCOPE :

The item shall include clearing site, excavation to the designed section, removal of thematerial, their sorting out as specified and their depositing either in spoil banks or oncanal banks in layers as specified including all leads and lifts.

2.2.0 CLEARING SITE :

The site of excavation and canal banks shall be cleared of all grass vegetation, fencing,bushes, trees as directed by the Engineer-in-charge. The materials, obtained from suchclearance shall be the property of the Corporation and shall be stacked as directed bythe Engineer-in-charge so as not to cause obstruction to the work.

2.3.1 LINE OUT :

All materials such as pegs, bamboos and strings and templates for marking out slopes,and labour required for line out shall be provided by the Contractor at his own cost. Thecenter line of excavation shall be clearly marked by pegs or by stones at each chainor change of direction or at shorter intervals on curves, in the begining. The final lineout will be done by fixing reference stone at suitable distances on either side of thecenter line, beyond the canal edges so that they are not disturbed during the constructionperiod. The position of these stones will be marked on the cross section.

2.3.2 No change in the sanctioned plans and designs is permissible without the writtenpermission of Engineer-in-charge.

2.3.3 Before starting the work, the Contractor shall have to sign the field books and plansshowing the working longitudinal sections and cross sections of the portions of thealignment, that he has to tackle. If the Contractor fails to sign them within three daysof being called upon to do so, the levels and sections as recorded by Engineer-in-charge or his Assistant will be final and binding on the Contractor.

SP - 15

2.4.0 EXCAVATION :

2.4.1 SCOPE OF WORK :

Along the excavation and removal of excavated material and its disposal in a mannerhereinafter specified, the rate for the item of excavation will also include.

(i) Clearing of site.

(ii) Setting out works, profiles etc. according to sanctioned plan, or as directed by theEngineer-in-charge and setting up bench marks and other reference marks.

(iii) Providing and subsequently removing shoring and strutting if and when necessary.

(iv) Bailing and pumping out water including continuous pumping till completion of theexcavation.

(v) Necessary protection including labour, materials and equipments to ensure safetyand protection against risk or accident.

(vi) Supply of facilities for inspection and measurements at any time to the concernedCorporation officials.

(vii) Compensation for injury to life and damage to property if any, caused byContractor’s operations connected with this item.

2.4.2 Canal section shall be excavated as shown on the drawings or as directed by theEngineer-in-charge. Both edges of the banks, specially the inner one shall be neatlyaligned symmetrically to the center line of canal. They shall be absolutely straightreaches and smoothly curved at bends.

2.4.3 Suitable arrangements for drainage shall be provided to take surface water clear ofexcavation during the progress of work.

2.4.4 Excavation may be carried out by manual labour or by excavating machine.

2.4.5 EXCAVATION IN ROCK :

Excavation in rock shall be such that all sharp points of rock are chipped off so as notto extend into the canal profile. Blasting in a manner which is likely to produce overbreakage which in the opinion of Engineer-in-charge is excessive, shall not be permitted.Special care shall be taken to prevent over-breakage, or loosening of materials onbottom and side slopes against which lining is to be placed. Excavation in excess ofthe prescribed canal section shall not be permitted beyond pay-line and no paymentwill be made for such excess excavation.

2.4.6 The material excavated in a chain of 20/30 meters shall be stacked on either side ofthe chain as specified on the drawing or as directed by the Engineer-in-charge.


SP - 16

2.4.7 The excavation shall be carried out according to the design with accurately graded bedfall and side property sloped as shown in the drawings and as directed by the Engineer-in-charge. The cross section adopted in cutting is likely to change in side slopesaccording to the depth of different strata during actual excavation. The Contractortherefore, should get clear instructions from Engineer-in-charge, before commencingany cutting work.

No claims for any variations in quantity of excavation resulting from the deviation fromthe instructions of the Engineer-in-charge, would be accepted. To account for this, thecentral box cutting with the canal bed width as its width have to be taken to canal bedlevel first, before the side slopes are determined and attacked (except for deep cuttingof more than 6m. depth). In portions where deep cutting of more than 6m. is to bedone, the mode of excavation to be followed must be got approved from the Engineer-in-charge, before starting the work in such reaches and in any case, width ofexcavation to be tackled initially shall not be more than bed width + depth.

The excavation should initially be carried out in steps. The steps should have suchwidth and depth that after they are cut. the required final side slopes is attained. Cuttingof steps should be done after bed level is reached and after one monsoon. If cuttingis in soft strata, cutting of steps should be done just prior or preparing the side slopesfor laying lining.

2.4.8 REMOVAL OF LOOSE ROCK ETC. :

Before any work of excavation is taken up, all loose rock, semi-detached rock in/orclose to the areas to be excavated, that is liable to fall or otherwise endanger theworkmen on the project shall be stripped. The methods employed shall be will notshatter or render unstable and therefore unsafe any rock that was originally sound orsafe. Any material not requiring removal as contemplated herein, but which may laterbecome loosened or unstable shall be promptly and satisfactorily removed. The costof such clearing shall be deemed to have been included in the unit rates acceptedunder the different items under excavation.

2.5.0 CLASSIFICATIONS :

2.5.1 The classification of strata shall be as under.

i) SOFT STRATA :

This shall include all kinds of rock or shale, indurated clay, soil, silt sand and gravel,soft average and hard murum and any other materials which can best be removed witha shovel after loosening with a pick and / or bar. It shall also include isolated bouldersupto 0.1 cubic metre each, which does not need blasting and could be removed witha pick / bar and shovel.


SP - 17

ii) HARD STRATA :

This shall include all rock occuring in masses in all types of geological formations whichcould best be removed by blasting, where such blasting is permissible. It shall alsoinclude rock which owing to the proximity of buildings / structures / electric lines publicroads or for any other reasons has to be cut by means of chisels or wedges. It shallalso include boulders in mass and isolated boulders over 0.1 cubic metre each whichrequires blasting or wedging and breaking for easy removal. Merely the use of explosivesin excavation shall not be considered a reason for classification in hard strata unlessregular blasting is clearly necessary in the opinion of the Engineer-in-charge. Thehardness of strata or material to be excavated, presence of different type of geologicalconstituents requiring increased drilling efforts, consumption of explosives, labour & useof machinery shall not be considered as reason for claim / increase in contract rates.

2.14.5 EXCAVATION OUTLINES AND PAY LINES :

2.14.5 All excavation shall be performed in accordance with the lines, grades, levels anddimensions shown in the drawing or established by the Engineer-in-charge. Thedimensions shown in the drawing are tentative. During the progress of work it maybe necessary or desirable to vary the slopes or the dimensions of excavation fromthose specified in the drawing. The side slopes of the excavation shall be as steep aswould stand with safety as decided by the Engineer-in-charge. If the slopes establishedare found to be steeper and likely to slip, they shall be made flatter by removing theadditional material and introducing suitable berms if possible and stable facesestablished. The additional excavation will be paid at the rate accepted for excavatoinfor particular class of material.

Excess Excavation :

No payment shall be made for the work done beyond specified pay lines. Normally paylines for different strata for excavation are defined as the lines starting from the outerdimension of the masonry or concrete at foundation level and sloping up as specifiedbelow :

a) Soft strata : 1.5 : 1

c) Berms with prior approval.

If in the opinion of Superintending Engineer the sides are unstable and prone to slip,modified pay lines will be laid down with flatter slopes & berms etc. as decided by him.

Any or all excess excavation carried out by the Contractor beyond approved pay linesfor any purpose or reason, shall unless ordered in writing be at the expense of the


SP - 23

Contractor, and if the unauthorised excavation has to be filled with concrete or masonryor with materials approved as filling so needed shall be carried by the Contractor asper specifications of the respective items of work at his own expense. Tolerance forover cut beyond pay lines arising out of peculiar nature of rock at the site and othersite conditions shall be decided by the Superintending Engineer-in-charge of the work.Payment for excavation beyond pay lines upto tolerance lines in such specific casesshall be made @ 60% tender rate of the particular item of the work. No tolerance shallhowever be permitted in soft strata.

2.14.6 OVER CUT :

Over cut is defined as the quantity of excavation beyond payment lines and the unitrate for the volume payable within paylines covers the cost of overcut unless otherwisespecified.

Over cut in soft strata shall be filled (with the materials specified for the backfill) backto the same standard of placement as stipulated for the backfill and is covered by thepayment under backfill item upto paylines unless otherwise specified.

2.14.7 MODE OF MEASUREMENTS AND PAYMENT :

The measurements shall be based on areas of cross-sections taken normal to the axisof the structure or its part of the original ground surface and the surface of the finallycompleted excavation within the paylines, taken at every 10 metres along the axis ofstructure or it part. Where there is abrupt change in depth, additional cross sectionsmay be taken at the discretion of the Engineer-in-charge.

4.11.0 FORMS :

4.11.1 GENERAL :

Forms to confine the concrete and shape it to the required line shall be used wherevernecessary. The form shall have sufficient strength and rigidity to hold concrete and towithstand the pressure of ramming and vibration without excessive deflection from theprescribed lines the more so when the concrete is in vibration. The Contractor shallhave to get the design and drawing of the centering approved from the Engineer-incharge before erection. Form work shall be of any of the following types.


SP - 50

(a) Wooden shuttering with steel plates lining or plywood shuttering.

(b) Steel shuttering.

For works costing more than Rs. one crore, only steel shuttering to be used. Howeveras per need of site, wooden shuttering would be allowed only if it is free from warpingand is fabricated true to line and shape. The decision of the Engineer-in-charge as tothe suitability of wooden shuttering as per (a) above to be used by the Contractor willbe and binding on the Contractor. The surface of all forms in contact with concrete shallbe clean, rigid, watertight and smooth. Suitable devices shall be used to hold corners,adjacent ends and edges of pannel of other forms together in accurate alignment.

4.11.2 DESIGN :

The detailed designs of the form work and false work shall be prepared by theContractor and got approved by the Engineer-in-charge well in time. Such an approvalhowever, will not relieve the Contractor of his responsibility for the adequacy andstrength of the form work and false work.

Forms shall be as designed and constructed as to be removable in sections withoutdamaging the surface of the concrete and with facilities of removal in ascending orderwithout disturbing the remaining forms required to be removed later.

4.11.3 MATERIAL :

The forms and false work shall be made of wood or metal. The timber from which theforms are prepared should preferably be partially seasoned. It shall be free from sap,shakes, loose knots, wormholes or other defects. The planks and scantlings shall besawn straight and all edges and planes shall be straight and free from warps. Partiallyseasoned soft wood is generally preferable for form work as it is difficult to drive nailsin hard wood. The dimensions of scantlings should conform to the design. The strengthof the wood shall not be less than that assumed in a design.

In metal forms, steel sheets of the designed gauge strengthened with framing of angleor other sections shall be used.

Wooden forms may also be lined within thin steel sheet or plywood to give the requiredsurface or finish.

4.11.4 FABRICATION :

The timber planks and scantlings of the designed dimensions shall be used in the formwork with appropriate spacing of studs, yokes, joists, girders etc. as provided in thedegns. All timbers in contact with concrete shall be brought on one face and two edges,the unbrought face being on the outside. The joints should be made mortar tight. Thismay be done either by providing tongued and grooved or revated joint or by caulkingor nailing to the construction operations. The nuts and bolt heads in side the form work


SP - 51

adjoining the concrete should be countersunk. The form work should allow finishedconcrete to have a smooth surface and conform to the shapes, lines and dimensionsshown on the plans and true to line and grade. The effect of vibration shall be takeninto account in the design and fabrication of the form and false work.

4.11.5 TREATMENT OF THE INNER SIDES OF FORMS :

Before placing concrete the inner side of the forms which come in contact with theconcrete shall be coated with mineral oil or any other suitable materials approved bythe Engineer-in-charge which will prevent adhesion of concrete to the forms but will notdiscolour the concrete. When oil is used, it shall be applied before reinforcement isplaced. Care shall be taken to see that reinforcement does not come in contact withcoating. All chippings, saw dust and other rubbish shall be removed from the interior ofthe forms before concreting.

4.11.6 FALSE WORK :

False work shall be built on foundation or base of sufficient strength to carry the loadswithout settlement. False work which can not be found on solid footing must besupported by piles or other similar devices. False work shall be designed to carry thefull loads including that due to construction operation comming upon it.

4.11.7 ERRECTION AND REMOVAL OF FORMS :

The false work and form work shall be errected with an eye for absolute safety of theform work and concrete work before and after pouring concrete. Watch should be keptto see that the behaviour of centering and form is satisfactory during concreting.Erection should also be such that it would allow removal of forms in proper sequencewithout damaging either the concrete or the forms to be removed later.

If there is failure of false work and / or form the Contractor shall be responsible for allthe consequent damages to work, injury to life and damage to property and make goodthe damage at his cost.

i) Before placing concrete the surface of forms shall be oiled with a suitablenonstaining oil such as raw linseed oil so as to prevent sticking of concrete andfacilitate the removal of form.

ii) The oil shall cover the forms fully and evenly without excess over drip. Care shallbe taken to prevent oil from getting on the surface of the construction joints andon reinforcement bars. Special care shall be taken to oil thoroughly the forms stripsfor narrow grooves so as to prevent swelling of the forms and the consequentdamage to concrete prior to or during removal of forms. Immediately beforeconcrete is placed, care shall be taken to see that all forms are in proper alignmentand the supports and fixtures are thoroughly secured all tightened.


SP - 52

iii) Where forms for continuous surface are placed in successive units, the form shallfit tightly over the completed surface so as to prevent leakage of mortar from theconcrete and to maintain accurate alignment of the surface.

iv) Forms shall be left in place until their removal is authorised and shall then beremoved with care so as to avoid injury to concrete.

v) Removal of forms shall never be started until the concrete is throughly set andhardened adequately to carry its own weight, beside the live load which is likelyto come on the work during constructions. The length of time for which the formsshall remain in place shall be decided by the Engineer-in-charge, with referenceto weather conditions, shape position of the structure or structural member and thenature and amount of dead and live loads.

In normal circumstances forms shall be struck after the expiry of the following period.

a) Walls, columns and vertical faces of all 24 to 28 hours as may be decidedstructural members by the Engineer-in-charge.

b) Slabs (Props left under) 3 days

c) Beam soffits (Props left under) 7 days

d) Removal of Props under slabs 1) Spanning upto 4.5 m 7 days 2) Spanning over 4.5 m 14 days

e) Removing of props under beams and arches 1) Spanning upto 6 m 14 days 2) Spanning over 6 m 21 days

Note : The number of props left under their size and disposition shall be such as to be ableto carry the full dead load of the slab, beam or arch as the case may be together withany live load likely to occur during curing or further construction.

In no case shall forms be removed until there is assurance that removal can beacomplished without damaging the concrete surface. No loads will be allowed todamage the concrete surface. Heavy load shall not be permitted until the concrete hasreached its designed strength. The forms shall be removed with great caution andwithout harming the structure or throwing heavy forms upon the floor.

4.11.8 RE-USE OF FORMS ETC :

Forms required to be used more than once shall be maintained in service able conditionsand shall be thoroughly cleaned and smoothened before reuse. Where metal sheetsare used for lining forms, the sheets shall be placed and maintained on the forms withminimum amount of wrinkles, humps or other imperfections. All forms shall be checkedfor shape and strength before reuse.

The forms and false work will be inspected, checked and approved by the Engineer-in-charge before concreting commences. But this will not relive the Contractor of hisresponsibility for strength, adequacy and safety of the form and false work.

4.12.10 CONCRETING DURING RAINTS :

When concreting is required to be done or continued while it shall be seen that theconcrete is not damaged due to rain while it is being tranported and placed After placingthe green concrete it shall be adequately covered for a period of 24 hours when it willbe capable for being cured by splash of water. The surface of fresh concrete shouldbe maintained on a slope sufficient for result in the self drainage of the rain water. Thework shall however be discontinued when the rain is so severs that water collects inpools or washes the surface of the fresh concrete and it is not possible to provideadequate shelter.

4.13.0 PLACING CONCRETE :

4.13.1 Concrete shall be placed only in locations where authorised and no concrete or mortarshall be placed until formwork, installations of embedded parts, preparation of surfaceor necessary clean up has been approved.

4.13.2 ROCK SURFACE :

Rock surface upon or against which concrete is to be placed, shall be prepared asspecified in section of excavation for foundation.

4.13.3 MASONRY SURFACE :

i) Masonry surfaces on which or against which concrete is to be placed, shall beprepared as described in para 9.2.1 and 9.2.2 of section 9. The unit rate formasonry shall cover the cost of such preparation.

ii) If the old layer of masonry which has been paid for is required to be removed asmentioned in para 9.2.2 it shall be back filled with concrete along with upperconcrete layer at no extra cost.

4.12.4 CONCRETE SURFACES :

Before laying of concrete the surface of the concrete in day work, shall be cleaned bya wire brush and jets of water, so that the surface is thoroughly cleaned and wettedbut pools of water are avoided. If the old concrete surface has remained exposed formore than two week, it shall be prepared not roughened by chipping to a depth of twocentimetres and the surface coated or covered with a layer of cement mortar (1:2) fora depth of 5 to 8 cm. The unit rate of concrete shall cover the cost of such prepartionand also the cost of cement mortar. The concrete removed for roughening shall not bepaid for.


SP - 54

4.13.5 ALL SURFACES :

i) The cleaned rock, masonry or concrete surface shall be applied with cement slurryand then cement mortar coat as described in para 9.2.2.

ii) The first few batches of concrete may, if as required contain half the regular sizeof coarse aggregate without any extra claims.

iii) The cost of such preparation work stands included in the unit rate of cementconcrete.

4.13.6 TIME FOR USE :

All concrete shall be placed directly in its final position within thirty minutes of mixing.Any concrete which has become so stiff that proper placing cannot be assured withoutretempering shall be wasted and shall not be paid for. All surface of forms and metalwork including reinforcement bars that have become encrusted with dried mortar ofgrout concrete previously placed shall be cleaned of all such mortar or grout beforesurrounding or adjacent concrete is placed.

4.13.7 METHOD OF PLACEMENT :

Before starting placing of concrete, it should be made certain that the transporting andplacing equipment is clean in proper order and that equipment along with the operatingstaff is arranged to deliver the concrete in the final positions without undue delays andobjectionable segregation. The methods and the equipment used for transport andplacing of concrete shall be such as will permit the delivery of concrete of the requiredconsistency into the work without objectionable segregation porosity or excessive lossof workability. Excessive segregation from whatever cause shall be prevented in handlingand placing operation by avoiding or controlling lateral movement of the concrete asin dumping at an angle depositing continuously at one point and allowing the concrete toflow. Concrete shall not be dropped from excessive heights and free fall should be keptto a minimum. Concrete shall be deposited in continuous horizontal layers in a thicknessof approximately 30cm. in normal work to 45 cm for mass concrete except that nothingherein shall be constructed to permit placement of the additional horizontal layers ofmass concrete before the entire area to be concreted is covered by previous layers.On flat, horizontal surfaces, where congestion of steel near the forms makes placingof concrete difficult, a mortar of the same cement sand ratio as used in the concreteshall be first deposited to cover the forms and shall stand included in the unit rate ofconcrete before the entire area to be concreted is covered by previous layers.

4.13.8 RATE OF PLACING :

Concreting should be continued without interruption until the structure or section iscompleted or until satisfactory construction joints can be made. Location of constructionjoints shall be as directed by the Engineer-in-charge. Concrete shall not be placed,faster than the placing crew can compact it properly. In placing thin members and


SP - 55

columns precautions shall be taken against too rapid placement which may result inmovements or failure of the forms due to excessive lateral pressure. An interval ofatleast 12 hours and preferably 24 hours should elapse between the completion ofcolumns and walls and the placing of slabs beams or girders supported by them inorder to avoid cracking due to settlement. All concrete shall be placed in approximatelyhorizontal lifts not exceeding 1.25 metre in thickness per day. Concrete in archesshall be done in strips extending from one pier to another. No through joints shall bekept in the span.

4.12.9 CONCRETING AT NIGHT TIME :

If concrete is to be placed at night adequate lightling arrangements shall be made, asdirected by the Engineer-in-charge.

4.12.10 CONCRETING DURING RAINS :

When concreting is required to be done or continued while it shall be seen that theconcrete is not damaged due to rain while it is being transported and placed. Afterplacing the green concrete it shall be adequately covered for a period of 24 hours whenit will be capable for being cured by splash of water. The surface of fresh concreteshould be maintained on a slope sufficient for result in the self drainage of the rainwater. The work shall however be discontinued when the rain is so severe that watercollects in pools or washes the surface of the fresh concrete and it is not possible toprovide adequate shelter.

4.13.0 COMPACTION :

4.13.1 GENERAL :

In all concrete works, required nos. of vibrators, with stand by in working condition willbe kept ready at site as per the instructions of the Engineer-in-charge.

4.13.2 All concrete shall be vibrated by mechanical vibrator of approved type so as to ensuredense concrete. Hand tamping and rolling shall not be used for compaction of concreteexcept in special circumstances with the express permission of the Engineer-in-charge. When immersion type vibrators are used they shall be used vertically at about45 cm. a part. The vibrators shall be inserted to the full depth of the newly laid concretelayer. The concrete shall be thoroughly compacted during depositing to get a denseconcrete and thoroughly worked in to the edges and corners of the form work and alsoalong its faces and thoroughly worked in to the edges and corners of the form work andalso along its faces and around reinforcement in the case of R.C.C. by means ofsuitable tools such as trowel and rods to get a good finish without honeycombing. Thevibrator shall nowever, not revibrate concrete which as commenced its final set. Specialcare shall be taken to see the vibrator touching the reinforcement of embedded partdoes not disturb the concrete below which has commenced its final set. The concreteshall not be vibrated excessively so as to cause segregation.


SP - 56

4.14.3 Each layer of concrete, for surfaces which is required to be smooth and for all surfaceswhich will be permanently exposed to the weather, and for all surfaces next to ambeddedmetal work shall be worked and vibrated by mechanical vibrator of approved type onlyso as to obtain a concrete of maximum density and impreviousness and to assure closecontact of the concrete with forms, reinforcement bars and other embeded parts. If themethods of transporting and placement have been conductive to air entertainmentsegregation of stiffening, the work of compaction should receive special attention.

4.14.4 For concrete surfaces exposed to flow of water special precaution shall be taken tominimise and to prevent surface pitting and protrusions without resorting to overmanipulation of the concrete mix to the forms. No plastering for getting a smooth finishshall be permitted at these locations. Any protrusion shall be ground smooth.

4.15.0 CURING AND PROTECTION :

All concrete shall be protected against injury until final acceptance. Exposed finishedsurface of concrete shall be protected from the direct rays of sun of atleast 72 hoursafter placement. Concrete shall be kept continuously moist for not less than 21 days.Construction joints shall be cured in the same ways as other concrete and shall alsobe kept moist for atleast 72 hours prior to the placing of additional concrete upon thejoints. Approximately horizontal surfaces shall be cured by sprinkling, ponding, or bycovering, or by damp sand or may be cured by the use of wet quilts or mats. Verticalsurfaces shall be by covering with wet jute bags. If damp sand or quilting used forcuring, it shall be removed completely later. Should the concrete that has become dryor powdery through neglect of curing the Contractor shall rectify the work at his ownextra cost. If curing arrangements by the Contractor are not satisfactory the Engineer-in-charge may in his discretion engage labour and provide material and equipment forcuring and recover expenditure thus involved from Contractor.

4.16.0 FINISHING :

4.16.1 GENERAL :

Finishing of formed and unformed surface shall be performed only by skilled workmen.All exposed concrete surface shall be cleaned of all incrustations of cement mortar orgrout. Unsightly stains shall be removed.

4.16.2 FORMED SURFACES :

Surface of concrete finished against form shall be smooth, free from projections andfilled thoroughly with mortar. Immediately upon removal forms, all usightly ridges or finesshall be removed and any local bulging on exposed surfaces shall be remedied bytooling and rubbing. All holes left by the removal of fasteners shall, after being reamedwith foothed reamer, neatly filled with dry patching mortar. All porous and fracturedconcrete & surface concrete to which additions are required to bring it to the prescribed


SP - 57

lines shall be sharp edged and keyed and shall be filled to required line with freshconcrete used for filling the chipped openings and these shall not be less than 8 cm.in depth and the concrete filling shall be reinforced and dowelled to the surface of theopenings. Honey combed surfaces and surfaces which give a hollow sound shall berectified by guniting at the Contractor’s cost within the unit rate accepted for concrete.

4.16.3 DRY PATCHING :

Dry patching mortar shall consist of one part of cement to 2 parts of sand by volumeand just enough water so that the mortar so used, will stick together on being mouldedinto a ball by a slight pressure of hands and will not exclude water when pressed butwill leave the hands damp. The mortar shall be placed in layers of not more than 2 cm.thickness. After being compacted each layer shall be roughened by being scratched toprovide an effective bond with the succeeding layers. The last of finishing layer shallbe smooth to form a surface cintinuous with the surrounding concrete. All patches shallbe bonded thoroughly to the surface of the chipped opening and shall be sound andfree from shrinkage cracks.

4.16.4 FINISHING PERMANENTLY EXPOSED SURFACE :

Except as otherwise specified or directed all permanently exposed concrete surface &other waterway surface requiring durability under water (except the outlet) shall befinished in the following manner. Immediately upon the removal of the form the surfaceshall be wetted and all surface pits and air bubbles filled by rubbing mortar composedof cement and fine sand in proporation (1:2) in to the pits with burlap so as to securea uniformly dense and smooth face.

The rubbing shall be performed in such a manner as to leave the surface free frommortar not used for filling the pits. Should the filling operation be unduly delayed andthe surfaces of the pits become coated with dirt or other contaminating materials, theyshall be thoroughly cleaned and washed and shall be maintained in a moist condition,until the mortar filling is placed. Such cleanings shall be done by means of air andwater jets and chipping of brushing or other satisfactory means without damaging thesurrounding concrete. All operations in connection with the filling of surface pits shallbe handled as quickly as practicable to minimise the period during which the concreteand mortar filling are exposed to the drying. When the treatment of a surface has beencompleted the surfaces shall be neat and of the same colour and texture as theadjoining concrete.

4.16.5 FINISHING CONCEALED SURFACE :

For exterior concealed surfaces below ground or back fill level or like surfaces nototherwise specified, no finish is necessary except that sandstreaks metal pockets,honey combing or other imperfections which are of consequence affecting strength,water tightness or protection of reinforcing steel from corrosion, shall be corrected andrepaired as prescribed for formed surface.


SP - 58

4.16.6 FINISHING UNFORMED SURFACE :

Unformed surface shall be finished by one or more of the operation of screedingfloating and trowelling of the surface should be done at proper time employingexperienced men and should be just sufficient to produce the desired finish, Screedingwhich gives the surface its approximate shape by striking off surplus concreteimmediately after compaction shall be accomplished, by moving a straight edge ortemplete with a sawing motion across wood or metal strips that have been establishedas guides. Where the surface is curved special screed should be brought true to formand grade by working it with a wooden float. If a coarse textured finish is desired or ifthe surface is to be steel trowelled a section or final floatings should be performed aftersome stiffening has occured and the surface moisture film or shine has disappeared.Where smooth dense finish is desired floatings shall be followed by steel trowellingsome time after moisture film or shine has disappeared from the floated surface andwhere the concrete has hardened sufficiently to prevent fine material and water frombeing worked out the surface. Excessive trowelling particularly at early time shall beavoided.

4.16.7 CHIPPING AND ROUGHENING CONCRETE SURFACE :

Surface upon or against which additional concrete is to be placed shall be chipped androughened to a depth not greater than 25 mm. Roughening shall be performed bychipping or other satisfactory methods and in such manner as not toloosen, crack orshatter any part of the concrete beyond the roughened surface. After being roughenedthe surface of the concrete shall be cleaned thoroughly of all loose fragments, dirt andother objectionable substances and shall be sound and hard in such conditions as toa sure good mechanical bond between old and new concrete. All concrete which is nothard, dense and durable shall be removed to the depth required to secure a satisfactorysurface.

4.16.8 DAMAGE DUE TO FLOODS - CORPORATION NOT RESPONSIBLE :

In case of damage of any of the concrete works due to floods, Corporation will not beresponsible and whatever corrective measures are required to be adopted shall bedone by the Contractor at his cost.

5. RUBBLE FILLING

1.0 Materials

The stones to be used shall be broken rubble with fairly regular shape and not weatheredor decayed stones. Stones shall be selected for their larger size. The stones shall beabout 0.015 cub. m. or 15 litres (about 1/2 c. ft.) in size unless otherwise ordered by theEngineer, having regard to the nature of the stone being quarried. The stones to be usedfor wedging in the joints between stones shall be chips of such size as to snugle fill upthe interstices in most cases. All suitable rubble obtained from foundation excavationshall be made use of first. The rate to be charged for this rubble to the contractor shallbe that which is entered in the schedule A and if not so entered, the Divisional schedulerate current at the time of tender.

2.0 Details of construction

Dewatering if necessary shall be done according to specification in Vol. II. The bed onwhich rubble filling is to be laid shall be cleared of all loose materials levelled andconsolidated and got approved by the Engineer before starting rubble filling. Rubble fillingbehind abutments, returns or wings shall be laid in regular horizontal layers of not morethan 30 cm. (about 12”) in thickness closely packed and compacted and firmly set withtheir broadest face downwards. The interstices between adjacent stones shall bewedged in with spauls of the proper size, well driven in with hammers or wooden malletsto ensure tightly packed layers. Such wedging shall be carried on simultaneously with theplacing in position of the largest stones in each layer and shall in no case be permittedto fall behind. Each layer shall be packed and completed before the upper layer is started.

Backfilling required to be done if any, on the river-side of the abutment, wings or returnsshall be done simultaneously with the filling on the landside. Special precautions shouldalso be taken to prevent wedging action against masonry. The masonry shall have beenfully cured before rubble filling.

3.0 Item to include

(1) Supplying broken rubble and spalls of approved quality and size.

(2) All labour, materials and use of equipment and tools for properly laying handpacking and compacting the rubble.

(3) Any other incidental charges to complete the work as per sanctioned plan includingdewatering unless separately provided in the tender.

4.0 Mode of measurement and payment

Rubble filling shall be measured in cubic metres limiting the dimensions to those shownin the plan or as directed by the Engineer. The dimensions shall be measured to twoplaces of decimals in metres and quantities worked out to two places of decimals ofa cubic metre.

No deduction shall be made for voids. The contract rate shall be for a unit of one cum.


SP - 61

6. F - FORM WORK

GENERAL

1. Forms shall be used, wherever necessary, to confine the concrete and to shape it to therequired lines. Normally all exposed concrete surfaces having slope steeper than 2horizontal to one vertical shall be formed.

2. The condition of forms influence not only appearance of the structure but also quality. Useof good form material and proper form construction and maintenance is very important infield control. The use of steel form work enhances. The appearance of placed concrete. Itshould be recognized that it is not particularly economical to use poor quality form. Toooften any savings from use of injudicious re-use of poor timber form are negated by manuallabour in repairs and final dressing of the structure to an acceptable appearance.

TOLERANCES

3. The form work shall be designed and constructed to the shapes, lines and dimensionsshown on the drawings within the following tolerances :

A. Linear Outline

(a) In any 6 m of length ± 12 mm

(b) In any 12 m of length ± 18 mm

B. Plumb, specified batter, or from the curved surfaces of all structures including thelines and surfaces of columns, walls, piers, buttresses etc.

(a) In 3 m of height ± 12 mm

(b) In 6 m of height ± 18 mm

(c) In 12 m of height or greater ± 30 mm

C. Deviations from specified dimensions

of cross-section of columns and beams. + 12 mm

- 6 mm

D. Deviation from dimensions of footings.

(a) Dimensions of plan + 50 mm

- 12 mm

(b) Eccentricity 0.02 times the width of the footing in the direction

of deviation but not more than 50 mm.

(c) Thickness ± 0.05 times the specified thickness.

Note : These tolerances apply to concrete dimensions only, and specified thickness not to thepositioning of vertical reinforcement steel.


SP - 62

WORKMANSHIP, CLEANLINESS, AND STRENGTH OF FORM WORK

1. The form work shall be of steel, timber forms shall not be allowed. Supports shallalso be of steel. Suitable wedges in pairs be provided to facilitate adjustment andsubsequent releasing of forms. The contractor shall furnish the details of hisproposed form work to the Engineer-in-charge for his approval before erectionthere-of.

2. All rubbish, particularly chippings, shavings, saw dust and grout etc. shall beremoved from the interior of forms before these are erected. Cleanliness of formsshall be again checked after the forms are in place and before the concrete isplaced. The face of the form work, which is to be in contact with the concrete shallbe cleaned and treated with suitable form oil or release agent. The form oil shall beapplied so as to provide a thin uniform coating to the forms without coating thereinforcement.

3. Forms shall have sufficient strength to with stand all pressure resulting fromconcrete placement and vibration without deflection from the prescribed linesduring and after the placement of concrete and shall be maintained rigidly inposition. Where form vibrators are to be used, it shall be ensured that the form workis adequately rigid to effective transmit energy from the form vibrators to theconcrete without damaging or altering the positions of forms. The forms shall bemade sufficiently rigid by use of ties and bracings to prevent any displacement orsagging. Suitable struts or stiffeners shall be used wherever considerednecessary. The forms shall be made mortar tight.

4. After the forms for concrete structures have been erected to line and grade, theyshall be meticulously inspected as to their adequacy. If the forms are not tight, therewill be a loss of mortar which shall result in honey-combing of concrete or a loss ofwater which shall cause sand streaking. If the inspection reveals that the forms arenot strong enough to hold the concrete or are not braced sufficiently to stay inalignment, the Engineer-in-charge shall immediately notify the contractor to setright the deficiencies and concrete shall not be placed before the forms are re-inspected and found OK. It shall also be checked during inspection that the formwork, as erected, conforms to the line, grade, alignment to the specified tolerancelimits. Fully adequate rigidity of forms is of paramount importance since thetolerance limits specified are for finished concrete and NOT for the forms. Use ofinternal vibrators requires that the forms be tight and strong.

5. Stability is a very important consideration in the construction of forms. Every oneconcerned including the contractor shall be made to understand that the commondeficiencies resulting in form failure are :

(i) inadequate cross bracing of shores;

(ii) inadequate horizontal bracing;


SP - 63

(iii) failure to regulate the rate of placement of concrete in the forms;

(iv) poor regulation of the horizontal balance of the form filling;

(v) abnormal form displacements during and after concrete placement;

(vi) no provision for lateral pressures; and

(vii) lack of adequate inspection of form work;

In form construction, it is very important that ready access be provided for properplacement, working, and vibration, and for inspection of these operations.

6. The surface of form work shall be made such as to produce surface finishes asspecified and the joints shall be tight enough to prevent loss of liquid/slurry/mortarfrom concrete. Joints between the form work and the previous lift shall be granttight.

HORIZONTAL CONSTRUCTION JOINTS

7. A very common blemish on formed concrete surfaces is the off-set often found athorizontal construction joints where the forms have given way a fraction of coupleof centimeters at the bottom of the new lift. For surfaces where appearance andalignment are of considerable importance, these off-sets shall be prevented by sosetting the forms as to fit snugly against the top of concrete in the previous lift andthen securing them so as to remain in tight contact during the concrete placingoperations. The anchoring shall be done by using an ample number of ties andbolts, above and within a few centimeters of the construction joint. The ties in thetop of previous lift cannot be relied on to prevent a slight spreading of the forms atthe joint. Forms shall overlap the hardened concrete in the lift previously placed bynot more than about 50 mm. though 25 mm lap is considered sufficient. Utmostcare shall, thus, be taken by the contractor to ensure that the construction joints aresmooth, free from sharp deviations, projections, or edges.

SPALLING FROM THE FACE OF CONCRETE

8. Occasionally, spalling may occur from the face of the concrete when forms areremoved. This is often caused by rough spots on the forms where mortar adheresstrongly enough to over come the tensile strength of the green concrete. Suchareas on the forms shall be cleaned, polished and then covered with a suitable formoil. Wire brushing of timber forms shall be done very carefully to remove the setmortar as else it may aggregate the situation.

FILLING OF BOL T HOLES (SHE-BOLTS) OR HOLES OF TIES/RODS

9. The holes left on the concrete surfaces by she-bolts or rods etc. shall be reamed,cleaned, and filled with “dry pack mortar” within a reasonable period of the removalof form work. Such filling shall be made flush with the concrete surface.


SP - 64

RE-USE OF FORMS

10. The forms required to be used more than once shall be maintained in a goodcondition and shall be thoroughly cleaned and repaired (if required) before reuse.Where metal sheets are used for lining the forms, the sheets shall be placed andmaintained in the forms without lumps or other imperfections. All forms shall bechecked for proper shape, cleanliness, and strength before re-use.

INSPECTION OF FORMS

11. The contractor shall inform the Engineer-in-charge well in time beforecommencement of placement of concrete in the forms to enable him or hisrepresentative to inspect the formwork as to its adequacy, suitability, alignment,strength and overall fitness; and such inspection shall not relieve the contractor ofhis sole responsibility for the safety of men, materials, equipment and the resultsobtained.

QUALITY ASSURANCE

12. Ok Card System shall be introduced. The format of ok card shall be determined bythe Engineer-in-charge and the contractor or his representative shall be required tofill in the first column of ok card against all relevant items (as prescribed by theEngineer-in-charge) and sign to indicate that these are in conformity withspecifications. There after the engineer; authorized by the Engineer-in-charge shallinspect these items and any defects pointed by him shall be duly rectified by him.Broadly, the items shall comprise of :

- Preparation of surface of forms, form oil applications;

- Alignment, tolerances;

- Stability, bearing and support adequacy, ties, and spacers;

- Final clean-up; and

- Final ok for concrete placement.

STRIPPING OF FORM WORK

13. The Engineer-in-charge shall be informed in advance by the contractor of hisintention to strike/remove any form. The forms shall not be removed until theconcrete has achieved adequate strength. As per IS : 456-2000, the concrete shouldhave achieved a strength of atleast twice the stress to which the concrete may besubjected at the time of removal of form work. While this criteria of strength shall bethe guiding factor for removal of form work, in normal circumstances, whereambient temperature does not fall below 150 C and where ordinary portlandcement is used, and adequate duringis done, following striking period of forms beadopted, which shall satisfy the above criteria of strength of concrete :


SP - 65

Type of form work Minimum period beforestriking form work

(a) Vertical form work to columns, 16-24 hourswalls, beams

(b) Soffit form work to slabs (props to be refixed 3 daysimmediately after removal of form work)

(c) Soffit form work to beams (props to be 7 daysrefixed immediately after removal of form work)

(d) Props to slabs :(1) Spanning upto 4.5 m 7 days(2) Spanning over 4.5 m 14 days

(e) Props to beams and arches(1) Spanning upto 6.0 m 14 days(2) Spanning over 6.0 m 21 days

For cements other than OPC and lower temperatures, the stripping time specified aboveshall be suitably modified by the Engineer-in-charge. The contractor shall ensure and it ishis responsibility that the number of props left under, their sizes and disposition shall besuch as to be able to safely carry the full dead load of the slab, beam, or arch, as the casemay be, together with any live load likely to occur during curing or further construction.

Forms shall be removed with care so as to avoid any damage to the concrete. Concretedamages, if any due to removal of forms, shall be promptly repaired by the contractor asper method of such repairs prescribed/directed by the Engineer-in-charge to his entiresatisfaction.

The cost of form is included in the concrete/lining item and will not be paid separately.
