CIVIL SPECIFICATIONS FOR SCHEDULE B1/1
ITEM NO. 1A TO 1D:
Excavation for foundation for following depths including sorting out and stacking of useful materials and disposing off the excavated stuff up to 50 Meter lead Up to 1.5m depth . Contractor shall furnish all tools, plants, instruments, qualified supervisory personnel, labour, materials, any temporary works, consumable, any and everything necessary, whether or not such items are specifically stated herein for completion of the job in accordance with specification requirements. Line out along the alignment of the pipe using lime getting it approved from Engineer in charge, breaking the surface and excavating up to the required depth. Along the alignment of pipe, the excavated material shall be kept 1.0 mtr. Away from the trench and protecting the excavated material till the work is complete. Excavation will be allowed to be carried out up to maximum 100 m length at a time. Further excavation shall be permitted only after laying of the pipe line is complete in the excavated trench. The road metal and also the rubble packing shall first be stripped off for the whole width of the trench/pit and separately deposited in such place or places as may be determined by Owner/Engineer. The excavated stuff shall be dumped at about 1 m away from the trench (within 50 M lead), properly in the line and approach shall be provided across the trench at a suitable interval for the public to cross over. The bidder/operator’s rate shall include breaking brickwork, concrete etc. No extra rate shall be payable for this work. This approval, however, shall not in any way relieve bidder/operator of his responsibility for any consequent loss or damage. The excavation must be carried out in the most expeditious and efficient manner. Side slopes shall be as steep as will stand safely for the actual soil conditions encountered. Every precaution shall be taken to prevent slips. If slips occur, the slipped material shall be removed and the slope dressed to a modified stable slope. Removal of the slipped earth will not be paid for if the slips are due to the negligence of bidder/operator. During excavation, large stones and rubble shall be separated and removed from the excavated soil and stacked separately. The material from excavation shall be deposited on either side of the trench leaving adequate clear distance from the edges of the trench and pit, or as may be necessary to prevent the sides of the trench pit to slip or fall, or at such a distance and in such a manner as to avoid covering fire hydrants, sluice valves, manholes covers etc. and so as to avoid abutting the wall or structure or causing inconvenience to the public and other service organizations or otherwise as Owner/engineer may direct. Bidder/operator shall take into account additional excavation if any as Owner/ Engineer may require in order to locate the position of water pipes, drains, sewers etc. or any other works which may be met within or about the excavation of trenches/pits while quoting the rates for excavation. Such service lines if met with during excavation shall be properly maintained by Bidder/operator, by means of shoring, strutting, planking over, padding or otherwise as Owner/Engineer may direct, and shall be protected by the Bidder/operator from damage during the progress of the work. All precautions shall be taken during excavation and laying operations to guard against possible damage to any existing structure/pipeline of water, gas, sewage etc. Utmost care shall be taken to see that the width of the trench at the top of pipe is not more than that specified. In case additional width is required it shall be provided only in the top portion from the ground level up to 300-mm above the top of pipe. If any extra width is provided in the area below this portion, Bidder/operator shall have to provide remedial measures in the form of lime concrete or rubble masonry otherwise at the discretion and to the satisfaction of Owner/Engineer. If rock is met with, it shall be
84
removed to 200 mm below the bottom of pipes and fittings/specials and the space resulting shall be refilled with murrum and properly consolidated. Bottom of trenches/pits shall be saturated with water well rammed wherever Owner/ Engineer may consider it necessary to do so. When welding is to be carried out with the pipes and specials in the trench, additional excavation of not more than 60 cm in depth and 90 cm in length shall be made at joints in order to facilitate welding. The excess excavated material shall be carried away from site of works to a place up to a distance as directed by Owner/Engineer. This shall be done immediately so as not to cause any inconvenience to the public or traffic. If the instructions from Engineer are not implemented within seven days from the date of instructions to cart the materials and to clear the site, the same shall be carried out by Owner/Engineer and any claim or dispute shall not be entertained in this respect. All materials to be excavated shall be classified by Engineer, into one of the following classes and shall be paid for at the rates tendered for that particular class of material. No distinction shall be made whether the material is dry, moist or wet. The decision of Engineer regarding the classification of the material shall be final and binding on Bidder/operator and not be a subject matter of any appeal or arbitration.
A. Loose or soft soil These shall include all kinds of soils containing murrum, sand, clay, loam, peat, ash, etc., which can generally be excavated by spade, pick axes and shovel, and which is not classified under “Dense or hard murrum”, “soft rock” and “hard rock”.
B. Dense or hard murrum These shall include all kinds of soils containing hard murrum and/or, dense murrum etc., which can generally be excavated by spade, pick axes and shovel, and which is not classified under “soft and decomposed rock” and “hard rock”.
C. Soft rock
This shall include rock, boulders, slag, chalk, slate, hard mica schist, laterite and all other materials which in the opinion of Engineer is rock, but does not need blasting and could be removed with picks, hammer, crew bars, wedges, and pneumatic breaking equipment. The mere fact that Bidder/operator resorts to blasting for reasons of his own shall not qualify for classification under `hard rock’. This shall also include excavation in macadam and tarred roads and pavements. Masonry to be dismantled will also be measured under this item.
D. Hard rock
This shall include all rock occurring in large continuous masses. Hard varieties of rock with or without veins and secondary minerals, which, in the opinion of EIC shall be considered as hard rock. This should be removed with picks, hammer, crew bars, wedges, chiseling and pneumatic breaking equipment etc. Blasting will not be allowed in working premises
The rate of payment shall be on Cu.m. basis.
ITEM NO. 2: - 1.5 M TO 3 M DEPTH ( 2A, 2B, 2C, 2D) Excavation for foundation for following depths including sorting out and stacking of useful materials and disposing off the excavated stuff upto 50 Meter lead from 1.5 to 3.00 mt depth. -Do - as per item No 1, but for 1.5 m to 3 m depth The rate of payment shall be on Cu.m. basis.

ITEM NO. 3: Providing and laying cement concrete work 1:1.5:3 (1- Cement: 1.5- Coarse sand: 3graded stone aggregates 20 mm nominal size) and curing complete excluding cost of formwork and reinforcement for reinforced concrete work
1.0 Materials : Water shall conform to M-1. Cement shall conform to M-3. Sand shall conform to M-6. Grit shall conform to M-8. Graded stone aggregate 20 mm. Nominal size shall conform to M-12.
2.0 General : The concrete mix is not required to be designed by preliminary tests. The proportion of the
concrete mix shall be 1 : 1.5 : 3 (1 cement : 1.5 coarse sand : 3 graded stone aggregate 10 mm. Nominal size) by volume. Concrete work shall have exposed concrete surface or as specified in the item.
The designation ordinary M-100, M-150, M-200, M-250 specified as per I. S. Corresponding approximately to 1 : 3 : 6, 1 : 2 : 4, 1 ½ : 3 and 1 : 1 : 2 nominal mix of ordinary concrete by volume respectively.
The ingredients required for ordinary concrete containing one beg of cement of 50 Kg By weight (0.0342 Cu. M.) For different proportions of mix shall be as under :
The water cement ratio shall not more than those specified in the above table. The cement content of the mix specified in the Table shall be increased if the quantity of water in a mix has to be increased to overcome the difficulties of placement and compaction so that the water-cement-ratio specified in the Table is not exceeded.
Workability of the concrete shall be controlled by maintaining a water-cement-ratio that is bound to give a concrete mix which is just sufficiently wet to be placed and compacted without difficulty with the means available.
The maximum size of coarse aggregate shall be as large as possible within the limits specified but in no case greater than one fourth of the minimum thickness of the member, provided that the concrete can be placed without difficulty so as to surround all reinforcement thoroughly and to fill the corners of the form.
For reinforced concrete work, coarse aggregates having a nominal size of 20 mm. Are generally considered satisfactory.
For heavily reinforced concrete members as in the case of ribs of main beems, the nominal maximum size of coarse aggregate should usually be restricted to 5 mm. Less than the minimum clear distance between the main bars, or 5 mm. Less than the minimum cover to the reinforcement whichever is smaller.
Where the reinforcement is widely spaced as in solid slabs, limitations of size of the aggregate may not be important and the nominal maximum size may sometimes be as great as or greater than the minimum cover.
Admixture may be used in concrete only with approval of Engineer-in-charge upon the evidence that with the passage of time, neither the compressive strength of concrete is reduced nor are other requisite qualities of concrete and steel impaired by the use of such admixtures.
3.0 Workmanship: 3.1 Proportioning: proportioning shall be done by volume, except cement which shall be
measured in terms of bags of 50 Kg. Weight. The volume of one such bag being taken as 0.0342 Cu. Meter Boxes of suitable sizes shall be used for measuring sand aggregate. The size of the boxes (internal) shall be 35 cms. X 25 cms. And 40 cms. Deep. While measuring the aggregate and sand, the box shall be filled without shaking ramming or hammering. The proportioning of sand shall be on the basis of its dry volume and in case of damp sand, allowances for bulk age shall be made.
3.2 Mixing : 3.3 3.2.1 For all work. Concrete shall be mixed in a mechanical mixer which along with other
accessories shall be kept in first class working condition and so maintained throughout the construction. Measured quantity of aggregate, sand, cement required for each batch shall be poured into the drum of the mechanical mixer while it is continuously running. After about half a minute of dry mixing, measured quantity of water required for each batch of concrete mix shall be added gradually and mixing continued for another one and a half minute. Mixing shall be continued till materials are uniformly distributed and uniform color of the entire mass is obtained and each individual particle of the coarse aggregate shows complete coating of mortar containing its
86
proportionate amount of cement. In no case shall the mixing be done for less than 2 minutes after all ingredients have been put into the mixer.
3.4 3.2.2 When hand mixing is permitted by the Engineer-in-charge for small jobs or for certain other reasons, it shall be done on the smooth watertight platform large enough to allow efficient turning over the ingredients of concrete before and after adding water. Mixing platform shall be so arranged that no foreign materials gets mixed with concrete nor does the mixing water flow out. Cement in required number of bags shall be placed in a uniform layer on top of the measured quantity of fine and coarse aggregate, which shall also be spread in a layer of uniform thickness on the mixing platform. Dru coarse and fine aggregate and cement shall then be mixed thoroughly by turning over to get a mixture to uniform color. Specified quantity of water shall then be added gradually through a rose-can and the mass turned over till a mix of required consistency is obtained. In hand mixing, quantity of cement shall be increased by 10 percent above that specified.
3.5 3.2.3 Mixers which have been out of use for more than 30 minutes shall be thoroughly cleaned before putting in a new batch. Unless otherwise agreed to by the Engineer-in-charge the first batch of concrete from the mixture shall contain only two thirds of normal quantity of coarse aggregate. Mixing plant shall be thoroughly cleaned before changing from one type of cement to another.
3.6 Consistency: 3.3.1 The degree of consistency which shall depend upon the nature of the work and methods of vibration of concrete, shall be determined by regular slumps tests in accordance with I. S. 1199-1959. The slumps of 10 mm. To 25 mm. Shall be adopted when vibrators are used and 80 mm. When vibrators are not used.
3.7 Inspection : 3.4.1 Contractor shall give the Engineer-in-charge due notice before placing any concrete
in the forms to permit him to inspect and accept the false work and forms as to their strength, alignment, and general fitness but such inspection shall not relive the contractor of his responsibility for the safety of men, machinery, materials and for results obtained. Immediately before concreting, all forms shall be thoroughly cleaned.
3.4.2 Centering design and its erection shall be got approved from the Engineer-in-charge. One carpenter with helper shall invariably be kept present throughout the period of concreting. Movement of labor and other persons shall be totally prohibited for reinforcement laid in position.

3.5.3 Unless otherwise agreed to by the Engineer-in-charge, concrete shall not be dropped into place from a height exceeding 2 meters. When trucking or chutes are used they shall be kept close and used in such a way as to avoid segregation. When concreting has to be resumed on a surface which has hardened, it shall be roughened, swept clean, thoroughly wetted and covered with a 13 mm. Thick layer of mortar composed of cement and sand in the same ratio as in the concrete mix itself. This 13 mm. Layer of mortar shall be freshly mixed and placed immediately before placing of new concrete. Where concrete has not fully hardened, all laitance shall be removed by scrubbing the wet surface with wire or bristle brushes, care being taken to avoid dislodgement of any particles of coarse aggregate. The surface shall then be thoroughly wetted all free water removed and then coated with neat cement grout. The first layer of concrete to be placed on his surface shall not exceed 150 mm. In thickness and shall be well rammed against old work, particular attention being given to corners and close spots.
87
3.5.4 All concrete shall be compacted to produce a dense homogeneous mass with the assistance of vibrators, unless otherwise permitted by the Engineer-in-charge for exceptional cases, such as concreting under water, where vibrators cannot be used. Sufficient vibrators in serviceable condition shall be kept at site so that spare equipment is always available in the event of breakdowns.
Concrete shall be judged to be compacted when the mortar fills the spaces between the coarse aggregate and begins to cream up to form an even surface. Compaction shall be completed before the initial setting starts i.e. Within 30 minutes of addition of water to dry mixture. During compaction, it shall be observed that needle vibrators are not applied on reinforcement which is likely to destroy the bond between concrete and reinforcement.
3.6 Curing: Immediately after compaction, concrete shall be protected from weather, including rain, running water, shocks, vibration, traffic, rapid temperature changes, frost and drying out process. It shall be covered with wet sacking, hassain or other similar absorbant material approved soon after the initial set and shall be kept continuously wet for a period of not less than 14 days from the date of placement. Masonry work over foundation concrete may be started after 48 hours of its laying but curing of concrete shall be continued for a minimum period of 14 days.
