EXCAVATION LINES IN WEAK ROCKS :

1.10 In portions of sections of the work, it may become necessary to support the rock by permanent supports, and the excavation may have to be increased to accommodate the supports. In such case, the payment line shall be taken normal to the center line of the supports,


170

200 mm (Two hundred millimeters) beyond the outer surface of the support. Payments will be made up to such extended payment line at the unit rate of excavation item.

SUBSEQUENT INCREASE OR REDUCTION IN DIMENSIONS :

1.11 If during the progress of excavation of any particular element of work, it is required to increase or reduce the cross-sectional dimensions of the excavations from those shown in the typical cross section on the drawings, the contractor shall, on being so directed by the Engineer, excavate the further portion to such increased or reduced dimensions at the same unit rate as tendered for the particular work. The Engineer will establish fresh minimum excavation line and the payment line shall be 300 mm. (Three hundred millimeter). Beyond such fresh minimum excavation line. The excavation already done shall also be enlarged to increased dimensions if so ordered by the Engineer. Such excavation shall be paid for at the unit rates accepted in the schedule of prices, for such an enlargement. The quantity measured under this item will be between the original payment line and new payment line which will be fixed by the Engineer. The quantity paid as per para 1.10 for over breaks due to natural cleavage etc. will however be excavated and interned to be plugged back with concrete.

1.12 All excavation shall be so done such that the rock around the periphery of the excavated final section shall not shattered loosened or otherwise weakend. Large overbreaks shall be avoided by suitable means such as light charges, ream holes or similar measures. AlI drillling and blasting shall be carefully performed so that the material outside the required line is not shattered.

SCALING OF ROCK :

1.13 After a face is blasted, gases removed and the face ventilated, all loose or loosened rock from the top and sides shall be removed as quickly as practicable by approved methods to avoid danger to workmen and equipment. Later, if any loose or loosened rock is noticed anywhere in the excavations, it shall be removed expeditiously. As the work advances trimming of rock surface remaining within the excavation lines shall be undertaken simultaneously. In no case shall trimming to postponed and left to be tackled last. This work is left to be done latter take lot of time and may involve avoid able delays resulting in postponement of 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.

(2) Water - Water shall conform to General specification No.VI (water)

(3) Fine aggregate - shall conform to general specification No.III

(4) Coarse aggregate - Coarse aggregate shall conform to General specification No. VIII


176

2.1 SIZE

The maximum size of coarse aggregate shall be as large as possible but normally not greater then 1/4th of the minimum thickness of the concrete member provided that in the case of R.C.C. this size presents no difficulty to surround the reinforcement thoroughly and fill up the corners of the, formwork fully and is less than the minimum cover by 6 mm. For plain concrete minimum size of the coarse aggregate may be up to 20 mm. (about 3/4") subject to the above limitation and provided no limiting size is specified in the special provisions.

For heavily reinforced concrete members such as ribs of beams, etc., the maximum size of aggregate shall be restricted 6 mm. (about 1/4") less than the minimum clear lateral distance between the reinforcement bars of 6 mm. (about 1/2") less than the cover whichever is smaller.

The grading between the maximum size and minimum size of 5 mm. (about 3/16") shall be such as to produce a dense concrete of the specified proportion and consistency that will work readily into position without segregation and with out the use of excessive water content and shall be within limits given in A.7.3.

3. PROPORTIONING MIX

In ordinary concrete, although proportion of cement of fine and coarse aggregate is specified by volume, the quantity of cement shall be determined by weight assuming one bag of cement weighing 50 kg. Fine and coarse aggregates shall be measured by weight

The ratio of the volumes of the fine and course aggregates may be varied within limits of 1:1½ to 1:2½ directed by Engineer to suit the maximum size of coarse aggregate, the grading, density, workability and strength without extra cost. But the sum of volumes of fine coarse aggregates given above for the particular mix.

The quantity of water shall be just sufficient, but not more than sufficient, to produce a dense concrete of required workability for its purpose. An accurate control shall be kept on the quantity of mixing water.

An allowance shall be made for surface moisture present in the aggregates, when computing water content as indicated in I.S. 456-1964.


177

In the case of reinforced concrete work, the workability shall be such that the concrete will surround and properly grip all the reinforcement. Water cement ration will be such as will give concrete just sufficiently wet to be placed and compacted without difficulty.

For vibrated concrete water content may be reduced 15 per cent to 20 per cent to give the required reduced slump.

4. MIXING

For all important works concrete shall be mixed in mechanical mixer at the site work. Care shall be taken to see that the mixer and other accessories are in first class working condition and maintained so throughout the construction. Mixing shall be controlled till there is a uniform distribution of the materials and a uniform colour is obtained and each individual particle of the coarse aggregate shall show a complete coating of mo0rtar containing its proportionable amount of cement. In no case mixing shall be done for less than 11/2 minutes. The water cement ratio shall range between 0.55 to 0.64 for 1.2.4 mix.

When had mixing is permitted by the Engineer it shall be done on a smooth water tight platform large enough to allow efficient turning over of the ingredients of concrete before and after adding water. Mixing platform shall be so arranged that no foreign material shall get mixed with concrete nor the mixing water shall flow out.

The cement in required number of bags shall be placed in a uniform layer on top of the measured quantity of fine aggregate required also spread in a layer of uniform depth in the mixing platform. Dry sand and cement shall then be added gradually through a rose and the mass turned over till a mortar of required consistency is obtained. The measured quantity of coarse aggregate shall then the placed on the mixing platform and wetted and the mortar added and the entire mass turned and returned until all the particles of the coarse aggregate are fully covered with morter and the mixture is of a uniform colour and required consistency.

Concrete shall have a consistency such that it will be workable in the required position and in the case of R.C.C. flow around reinforcing steel also.

For vibrated concrete, slump shall range between 2.5 cm. to 5 cm. to (about 1" to 2") For hand tamped concrete, slump shall range between 8 cm. to 13 cm. (3" to 5") according to the type and nature of the concrete item. The slump shall be the least permitted by workability.


178

The slump shall be determined as detailed in appendix G of I.S. 456-1964 and maintained throughout the concerning operation of a member.

The concrete shall be placed in its final position and rammed, vibrated and finished within 30 minutes of adding water to cement. Retempering or remixing of partially hardened concrete shall not be permitted.

5. SCAFFOLDING

All scaffolding, hoisting arrangements and ladders etc. required for the facility of concreting shall be provided by the contractor at his own expense and removed on the completion of work. The scaffolding, hoisting arrangements and ladders, etc. shall be strong enough to withstand all love, dead and impact loads exported to act and shall be subject to the apparel of the Engineer. However, the contractor shall be solely responsible for the safely for the scaffolding hoisting arrangements, ladders, work and workmen. The contractor shall pay all the necessary compensations arising out of the use of scaffolding hoisting arrangements and ladders and for damages to work property and injuries to persons.

The scaffolding, hoisting arrangements and adders shall allow easy approach to the work spot and afford easy inspection.

5(a) FORMS

Forms shall generally comply with I.S. 456-1964, para 7.2

5(b) DESIGN

The detailed designs of the formwork and falsework shall be prepared by the contractor and got approved by the Engineer well in time. Such an approval, however, will not relive the contractor of his responsibility for the adequacy and strength of the formwork and falsework.

5(c) MATERIALS

The forms and false work shall be made of wood or metal. The timber from which the forms are prepared should preferably be partially seasoned, as to dry a timber will swell from absorption of moisture while green timber will dry and shrink. It shall be free from sap, shakes, loose knots, workwhole or other defects. The planks and scanlings shall be sawn straight and all edges and planes shall be straight and free from warps. Partially seasoned soft wood is


179

generally preferable for formwork as it is difficult to drive nails in hard wood. The dimensions of scntlings should conform to the design. The strength of the wood shall not be less then that assumed in the design.

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

Wooden forms may also be lined with thin steel sheets of plywood to give the required or finish.

5.(d) 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 the design. All timber in contact will concrete shall be wrought on one face and to edges, the unwrought face being on the outside. The joints should be made mortar tight. This may be done eigher by providing tongued and proved or rebated joints or by caul king or nailing metal strips or applying adhesive tape on the joints. The forms shall be built with sufficient strength and rigidity and held in shape by bolts, clamps, ties nails, wales or other contrivances or prevent distortion or collapse due to pressure of concrete and other loads incidental to the construction operations. The nuts and bolt heads inside the formwork adjoining the concrete should countersunk. The formwork should allow finished concrete to have a smooth surface and conform to the shapes, lines and dimensions shown on the plans and true to line and grade. The effect of vibration shall be taken into account in the design and fabrication of forms and false work. Forms shall be so designed and constructed as to be removable in sections without damaging the surface of the concrete and with facilities of removal in the ascending order or removal time, without disturbing the remaining forms required to be removed later.

5.(e) TREATMENT OF THE INSIDE OF FORMS

Before placing concrete the inside of the forms which comes in contact with the concrete shall be coated with mineral oil or any other suitable material approved by the Engineer which will prevent adhesion of concrete to the forms but will not discolor the concrete. When oil is used, it shall be applied before reinforcement is placed. Care shall be taken to see that reinforcement does not come in contact with the coating. All chipping, saw dust and other rubbish shall be removed from the interior of the forms before concerning.


180

5(f) FALSEWORK

Falsework shall be built on foundation or base of sufficient strength to carry the load without settlement. Falsework which cannot be founded on solid footing must be supported by piles or other similar devices. Falsework shall be designed to carry the full loads including that due to construction operations coming upon it.

5.(g) ERECTION

The falsework and formwork shall be erected with an eye for absolute safety of the formwork and concrete work before, during and after pouring Concrete. Watch should be kept to see that the behavior of centering and formwork is satisfactory during concerning. Erection should also be such that it would allow removal of forms in proper sequence without damaging either the concrete or the forms to be removed later. If there is failure of falsework and/or formwork the contractor shall be responsible for all the consequent damages to work injury to life and damage to property.

5.(h) INSPECTION

The forms and falsework will be inspected, checked and approved by the Engineer before concreting is commenced. But this will bot relieve the contractor of his responsibility for strength, adequacy and safety of the formwork and falsework.

5.(i) REMOVAL OF FORMS

Formwork shall be removed carefully without damaging the concrete or giving sudden shocks. It should be ascertained from the exposed sides of concrete that it has gained adequate strength before the bottoms and supports of the formwork are removed.

Unless otherwise specified in the special provisions, forms of concrete work using ordinary Portland cement may be struck after expiry of the following periods in normal circumstances :-

(i) Vertical sides of slabs beams, columns 40 hours

(ii) Bottoms of slabs up to 4.5 m. span 7 days

(iii) Bottoms of slabs of more than 4.5 m. span 14 days bottoms of beams and archribs, up to 6 m. span

(iv) Bottoms of beams and archribs of more than 6 m. 21 days span in important structures, the sequence of striking formwork shall be approved by the Engineer.


181

5.(j) REUSE

Before reuse, all forms shall be thoroughly scraped and cleaned, joints gone over and repaired and the insides retreated to prevent adhesion, all to the entire satisfaction of the Engineer. The shape, strength, rigidity, mortar lightness and surface smoothness of reused forms shall be maintained at all times.

6. TRANSPORTING

The concrete shall be handled from the place of mixing to the final position as quickly as practicable by methods which will prevent segregation and loss of ingredients. In no case shall be operation take more than 15 minutes.

7. PLACING

The concrete shall be placed into its final position, compacted and finished within 30 minutes of mixing the water and before setting commences. The methods of placing shall be such as to avoid segregation. Placing shall be done in a balanced manner to avoid eccentric loads on formwork.

As far as practicable the concrete for a particular portion shall be done in one continuous operation. The construction joints when required shall be made only where located on the plans or shown in the pouring schedule unless otherwise approved by the Engineer. The joint shall be regular and vertical and shall be made by placing a bulkhead at the joint. Before commencing subsequent concreting, all loose particles, Latinate, etc. shall be removed and the surface shall then be covered by thick cement slurry as part of placement. Care shall be taken during the placing not to disturb the forms or the reinforcement. Concrete compacted manually, shall preferably be laid in layers of 15 cm. (about 6" to 8") the layers being decided by the time lapse between the successive layers. The time of laying one layer shall not exceed 30 minutes. The successive layers shall commence within 30 minutes.

When work is to be resumed on a surface which has hardened, such a surface shall be roughened and scrubbed with brushes to remove laitance, care being taken to avoid dislodgement of coarse aggregate, swept clean, thoroughly wetted and covered with 6 mm. (about 1/4") thick mortar layer composed of cement and sand in the same proportion as the cement and sand in the concrete, immediately before the commencement of concrete, for securing good bond.


182

The concrete shall be normally laid in the dry. If the area is under water. It shall be pumped dry and kept so white placing concrete and till it sets. Where it is necessary to deposit concrete under water. It shall be done as per I.S.456-1964 para 7.17 No extra payment will be made for the special arrangements, plant etc., need for the purpose or for the additional to per cent cement required to be added.

8. COMPACTING

The concrete shall be thoroughly compacted during depositing to get a dense concrete and thoroughly worked into the edges and corners of the formwork as also along its faces and around reinforcement in the case of R.C.C. by means of suitable tools such as spades and rods to get a good cast finish without honey combing. Concrete shall not be disturbed once it is set.

For important or big works where stiffer mix, with less slump is adopted, use of mechanical vibrators is essential. The vibrators shall have not less than 3.600 and preferably about 5.000 impulses per minute and shall be worked at an interval of about 60 cm. (about 2') It shall worked in one place for only such time as will allow formation of dense concrete without sinking and segregation of the coarse aggregate. Over vibration shall be avoided. Vibration shall be aided by spading and rodding.

9. CURING

The concrete shall be initially protected from damage on account of impact undue pressure, excessive heat of sun, rain, etc. and covered with wet sacking, hession or similar absorbent material soon, after the initial set. After the final set. The concrete shall be kept continuously wet preferably by pounding water for a period of not less than 14 days from the date of placement. On Sundays, holidays and days of cessation of work, arrangement shall be made to keep the concrete continuously watered.

Should the contractor fail to water the concrete continuously, the Engineer may provide labour, materials and equipment required for watering and recover the cost from the contractor.

When atmospheric temperature exceeds 400c (140oF) following precautions should be taken

1) Stacking aggregates under shade and keeping them moist.

2) Using cold water


183

3) Reduce the time between mixing and placing to the minimum

4) Cooling formwork by sprinkling water

5) Starting curing before concrete dries out

6) Restricting concreting to mornings and evenings

10. FINISHING

Immediately after the removal of forms, any undulations, depression cavities, honey combing, broken edges or corners, high sport and other defects shall be made good and finished with cement mortar 1:2 but the necessity of such finishing must be exceptional and the total surface requiring finishing shall not exceed 12 per cent, on an average. If the initial experience shows that this percentage is exceeded the method of working itself should be changed to get the required cast finish.

Where the concrete surface is to receive plaster, the surface shall be roughened immediately after removal of forms and within a day thereof to secure a hold for the plaster. The rate for concrete is inclusive of this roughening and finishing. Concrete after finishing shall be cured for the full period.

11. RETAMPERING

Concrete shall be mixed only in such quantities as are required for immediate use and any concrete which has developed initial set shall not be used. Concrete which is partially hardened shall not be retempered or re-mixed but shall be destroyed or thrown away.

12 SAMPLING AND TESTING

Sampling of materials and concrete shall be done carefully by the contractor under the direct supervision of the Departmental staff as per I.S.456-1964 at the cost of the contractor. All necessary labour, materials, equipment, etc. for sampling preparing test cubes, curing etc., shall be provided by the contractor. Testing of the materials and concrete will be arranged by the Department in an approved laboratory at the cost of the contractor No. plea will be entertained later on the ground that casting of the test specimen was faulty and that the result of the test specimen was faulty and that the result of the test specimen did not give a correct indication of the actual quality of concrete, Compressive strength of ordinary concrete shall not be less than those specified in General specification. IV-2


184

One set of six 15 cm. (about 6") cubes shall be prepared from the concrete to be used in the work for compression test on each of the first three days operation and thereafter for every 60 cum. of concrete or three days work whichever is less, by the contractor in the presence of a responsible officer of the Department of a rank not less than, that of an Junior Engineer. If the source of aggregate or grading is changed, one set of six test cubes shall be taken for each changed batch. Three cubes shall be used for test 7 days age and three at 28 days.

After the relation between strengths at 7 days and 28 days is reliably established for the particular set of materials from the same sources, subsequent tests may be carried out only on three cubes at 7 days. If the average strength of the cubes show ultimate compressive strength less than the above, the Engineer shall have a right to order o change in the mix or water content for the remaining concrete without extra cost. Defective concrete having strength below 80 per cent of the required strength is liable to be rejected. Concrete of strength up to 80 per cent of the required strength may be accepted as substandard work at a reduced ate provided such weak concrete is restricted to such members and in such quantities as will to endanger the safety of the structure.

13. KEEPING RECORD

A day-to-day record authenticated by a responsible officer of the department and representative of the contractor, in the proforma approved by the Engineer shall be maintained by the contractor on the work site and kept open for inspection. This shall contain important information such as receipt of cement on the work site daily use with details of use on various items, time of starting concreting and closure, number of batches through the mixer, source of water, water cement ration of concrete, slump, dates of erection of formwork passing of formwork by the competent authority, dates of striking of forms, periods and method of curing and other events worthy of note. On completion of the work, the record shall be handed over to the Department.

Item No.11:- Dewatering by diesel or electrical pumping set for tunnel during construction including material and mechanical machinery charges fuel charges during operation and maintenance charges etc complete

1.1 GENERAL

The foundation trenches shall be kept dry by resorting for pumping along or pumping in combination with diversion channel, coffer dams, bunds diversion weirs, drainage channels well points or any other satisfactory method to suit local conditions at the choice of the contractor. The contractor shall supply details of his proposals for approval of the Engineer but such approval shall in no way release the contractor from the responsibility for the adequacy of diversion and


186

dewatering arrangement & for the quality and safety of the work, for all of which the contractor shall be solely responsible.

1.2 METHOD

The method to be adopted shall be entirely left to the choice of the contractor provided adequate dewatering is carried out and the scheduled programme is adhered to. The contractor shall plan, construct and maintain satisfactorily necessary diversion channels and temporary diversion and protective works so as to safely pass the stream flow & also satisfactorily deal with any sudden rise of flow without damaging the foundation works. And braced or protected by coffer dams. The coffer dam should be carried to adequate depths and heights, safely designed and constructed with suitable dimensions and protection and shall be made as water-tight as practicable cable for facility of construction of the work to be done inside them.

The interior dimensions of the cofferdams shall be such as to give sufficient clearance for the construction and inspection and to permit installation of pumping machinery etc. inside the enclosed area. The coffer dams shall be of sufficient heights to prevent seepage of water in to the foundation pits and to protect green concrete or masonry against damages of the foundation by erosion.

Unless otherwise permitted, no excavation shall be made outside the enclosed area and the natural stream bed adjacent to the foundation shall not be disturbed without the permission from the Engineer-in-charge.

Cement grouting or other approved methods may be used at the discretion of the contractor to prevent or reduce seepage and to protect the area to be excavated if the soil is porous.

1.3 PUMPING

Adequate pumping arrangements shall be made for dewatering foundation trenches and other areas of construction where dewatering is essential for keeping them dry while masonry or concrete or other construction is in progress and till the concrete or mortar or masonry has sufficiently set and construction can be proceeded without pumping.

Pumps of adequate capacity in required number and stage shall be provided to ensure the above. Pumping from the foundation trenches or from the interior of the coffer dam or other area of construction shall be done in a such a manner as to preclude the possibility of passage of water.


187

Through any fresh concrete or morter no pumping will be allowed during placing of concrete or for a period of at least 24 hours thereafter unless it is done through suitable sump separated from concrete or masonry by effective means.

The contractor should make his own arrangements for necessary labour, materials and equipments for coffer dams, pumps, engines and other machinery and devices required for successful execution of the item of dewatering.

1.4 DESILTING

If any foundation pits are filled due to floods or flow or slips, during the progress of the work or during rainy season or due to any other causes, all pumping required to dewater the pits and to doe desilting shall be done without making extra claims. Without extra cost.

1.5 SHORING ETC.

Staging, shoring, strutting, pumps and other protective works required for facility of dewatering shall be designed and put up the contractor to ensure full safety to the work, workmen, machinery and property and shall be removed after they have served their purpose in a manner and to the extent directed by the Engineer. The contractor shall be responsible for all damage and injury cause by the execution of this item.

1.6 REMOVAL

The cofferdams and other works constructed, for facility of diversion and/or dewatering shall not cause any damage to the property and the work and shall be removed after they have served their purpose in the manner and to the extent directed by the Engineer. If any excavation is made outside the enclosed area for facility of construction the contractor shall refill the same with proper ramming after foundation work is completed so as to bring the river bed to its original conditions as directed by the Engineer. Similarly any material deposited within the stream area from the filling of cofferdam or from any excavation shall be removed and the stream area made free from any obstructions caused thereby as directed by the Engineer.

1.7 ITEM TO INCLUDE

1.7.1 Diversion of surface flow construction of cofferdams, cribs, shoring strutting, bunds, service path during construction and removing the same after completion to bring the river bed to its original condition.


188

1.7.2 All labour materials use of equipment & other arrangement necessary for dewatering during excavation and construction of other items requiring dewatering.

1.7.3 Dewatering foundation trenches excavation and other structures built upon to enable the masonry, concrete or other construction work to be done in the dry and till the Engineer considers that the mortar or concrete has sufficiently set.

1.7.4 Dewatering till all the items till all the items requiring dewatering are fully completed. This shall also include time required for passing foundations and taking measurements of all the items requiring dewatering.

1.7.5 Removing liquid stuff of any sort which might find access into the trenches by blowings, slip or any other cause whatsoever from the sides or bottom of the foundation or excavation or from elsewhere during or after dewatering.

1.8 MODE OF MEASUREMENT AND PAYMENT

The payment of this item will be on the basis of actual pumping hours for which pumps have been operated by the contractor. A series of record will be maintained by the contractor and got signed by the Engineer-in-charge or his authorised subordinate. The inaction of 1/2 hour will not be counted however if pump runs for 1/2 hour or more it will be counted as 1 hour. Measurement will be for full hours. The contractor is expected to use his proper skill and machinery to resists the dewatering hours within the provision in Schedule 'B' of this item.

The contract rate shall be per on B.H.P. hour of pumping water.

RATE

This total B.H.P. hours for a period shall be summed up and paid for in R.A. Bill at the rate quoted. The rate includes cost of running the equipment, cost of setting of pumping machinery and lead pipes, channels etc. to carry out water away from site of work and other incidental works like sump bunds etc. for which no extra charges will be paid. The contractor should carry out dewatering in effective manner. The tenderer had no choice of rate for his item and no above or bellow percentage rate quoted by him is allowed, to be paid to the tenderer. This item is meant to cover dewatering charges for all item of work and is fully payable only after completion of entire work to the satisfaction of the Engineer-in-charge.
