The cement concrete 1:2:4 (1 cement: 2 coarse sand: 4 Hand broken stone aggregate (20 mm size)] in Foundation, coping and flooring at any depth or level shall be carried out in true line and level and have the width and depth as shown in the drawing or as directed including sorting out and stacking of useful materials and disposing of excavated stuff up to 50M. Lead for loose or soft soil. The contractor shall do the necessary shoring and shuttering to a safe angle, at his own cost.

(A) Materials: Water, Sand, Cement & graded hand broken stones aggregate of 20 mm. nominal sizes shall conform to standard specifications as per relevant BIS. Codes. Further details specifications of Materials are as under:

(B) Water: Shall be as per M1.

(C) Cement: Shall be as per M3. (D) Sand: Shall be as per M6.

(E) Stone Coarse Aggregate For Nominal Mix Concrete: Shall be as per M12.

(F) General: The concrete mix is not required to be designed by preliminary tests. The proportion of the concrete mix shall be 1 : 2 : 4 (1 cement : 2 coarse sand : 4 graded stone aggregate 20 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: 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 beams, 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.

(G) Workmanship:

a) 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.

b) Mixing: 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 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. 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 get 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. Dry 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. 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. c) Consistency: 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. d) Inspection: 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. 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. For access to different parts, suitable mobile platforms shall be provided so that steel reinforcement in position is not disturbed for ensuring proper cover; mortar blocks of suitable size shall be cast and tied to the reinforcement. Timber, kapachi or metal pieces shall not be used for this purpose.

e) Transporting and laying: The method of transporting and placing concrete shall be as approved. Concrete shall be so transported and placed that no contamination, segregation or loss of its constituent material takes place. All formwork shall be cleaned and made free from standing water, dust show or ice immediately before placing of concrete. No concrete shall be placed in any part of the structure until the approval of the Engineer-in-charge has been obtained. Concerting shall proceed continuously over the area between construction joints. Fresh concrete shall not be placed against concrete which has been in position for more than 30 minutes unless a proper construction joints is formed. Concrete shall be compacted in its final position within 30 minutes of its discharge from the mixer. Except where otherwise agreed to by the Engineer-in-charge concrete shall be deposited shall be deposited in horizontal layers to a

compacted depth of not more than 0.45 meter when internal vibrators are used and not exceeding 0.30 meter in all other cases. 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. 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.

f) 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, hessian or other similar absorbent 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.

g) Sampling and Testing of concrete: Samples from fresh concrete shall be taken as per I. S. 1199-1959 and cubes shall be made, cured and tested at 7 days or 28 days as per requirements in accordance with I. S. 516-1959. A random sampling procedure shall be adopted to ensure that each concrete batch shall have a reasonable chance of being tested i.e. The sampling should be spread over the entire period of concreting and cover all mixing units. The minimum frequency of sampling of concrete of each grade shall be in accordance with following:

Quantity of concrete in the work

No. Of samples Quantity of concrete in the works

No. Of samples

1-5 Cmt. 1 16-30 Cmt. 3

6-15 Cmt. 2 31-50 4

51 and above + one additional for each additional 50 M. Or part thereof. NOTE: At least one sample shall be taken from each shift. Ten test specimens shall be made from each sample, five for testing at 7 days and the remaining five at 28 days. The samples of concrete shall be taken on each day of the concreting as per above frequency. The number of specimens may be suitably increased as deemed necessary by the Engineer-in-charge when procedure of tests given above reveals a poor quality of concrete and in other special cases. The average strength of the group of cubes case for each day shall not be less than the specified cube strength of 150 kg/Cm2 at 28 days. 20% of the cubes cast for each day may have value less than the specified strength provided the lowest value is not less than 85% of the specified strength. If the concrete made in accordance with the proportions given for a particular grade, does not yield the specified strength, such concrete shall be classified as belonging to the appropriate lower grade. Concrete made in accordance with the proportions given for a particular grade shall not however, be placed in a higher grade on the ground that the test strength are higher than the minimum specified. h) Stripping: The Engineer-in-charge shall be informed in advanced by the contractor of his intention to strike the form work. While fixing the time for removal of form work due consideration shall be given to local conditions, character of the structure the weather and other condition that influence the setting of concrete and of the materials used in the mix in normal circumstances (generally where temperatures are above 20ºc) and where ordinary concrete is used forms may be struck after expiry of periods specified in item No. 9.1 (A) for respective item of form work. All formwork shall be removed without causing any shock or vibration as would damage the concrete. Before the soffits and struts are removed the concrete surface shall be exposed where necessary in order to ascertain that the concrete has sufficiently hardened. Centering shall be gradually and uniformly lowered in such manner as to permit the concrete to take stresses due

to its own weight uniformly and gradually. Where internal metal ties are permitted they or their removable parts shall be extracted without causing any damage to The concrete and remaining holes filled with mortar. No permanently embedded metal part shall have less than 25 mm cover to the finished concrete surface. Where it is intended to re-use the formwork, it shall be cleaned and made good to the satisfaction of the Engineer-in-charge. After removable of form work and shuttering the Executive Engineer shall inspect the work and satisfy by random checks that concrete produced is of good quality. Immediately after the removal of forms all exposed bolts etc., passing through the cement concrete member and use for shuttering or any other purpose shall be cut inside the cement concrete members to a depth of at least 25 mm. Below the surface of the concrete and the resulting holes be filled by cement mortar. All fine caused by form joints, all cavities produced by the removal of forms ties and all other holes and depressions honeycomb spots broken edges or corners and other defects shall be thoroughly cleaned, saturated with water and carefully pointed and rendered true with mortar of cement and fine aggregate mixed in the proportion used in the grade of concrete that is being finished and of as dry consistency as is possible to use. Considerable pressure shall be applied in filling and pointing to ensure through filling in all voids. Surfaces which are pointed shall be kept moist for a period of 24 hours. If rock pockets honeycombs in the opinion of the Engineer-in-charge are of such an extent or character as to affect the strength of the structure materially or to endanger the life of the steel reinforcement he may declare the concrete defective and require the removal and replacement of the portions of the structure affected.

2. Cement mortar: Shall be as per M11. 3. Workmanship :

Scaffolding: Wooden bellies, bamboos, planks, treadles and other scaffolding shall be sound. These shall be properly examined before erection and use. Stage scaffolding shall be provided for ceiling plaster which shall be independent of the walls.

Preparation of back-ground: The surface shall be cleaned of all dust, loose mortar droppings, traces of algae, efflorescence and other foreign matter by water or by brushing. Smooth surface shall be roughened by wire brushing if it is not hard and by racking if it is hard. In case of concrete surface, if a chemical retarder has been applied to the form work, the surface shall be roughened by wire brushing and all the resulting dust and loose particles cleaned off and care shall be taken that none of the retarders is left on the surface. Trimming of projections on brick/concrete surface where necessary shall be carried out to get an even surface. Racking of joints in case of masonry where necessary shall be allowed to dry out for sufficient period before carrying out the plaster work. The work shall not be soaked but only damped evenly before applying the plaster. If the surface becomes dry such area shall be moistened again. For external plaster, the plastering operation shall be started from top floor and carried downwards. For internal plaster, the plastering operations may be started whenever the building frame and cladding work are ready and the temporary supporting ceiling resting on the wall of the floor have been removed. Ceiling plaster shall be completed before starting plaster to walls.

Applications of plaster: The plaster about 15 x 15 cm shall be first applied horizontally and vertically at not more than 2 meters intervals over the entire surface to serve as gauge. The surfaces of these gauges shall be truly in plane of the finished plastered surface. The mortar shall then be applied in uniform surface slightly more than the specified thickness, and then brought to a true surface by working a wooden straight edge reaching across the gauges with small upward and sideways movement at a time. Finally, the surface shall be finished off true with a trowel or wooden float according as a smooth or a sandy granular texture is required. Excessive trowel ling or overworking the float shall be avoided. All corners, arises, angles and junctions be truly vertical or horizontal as the case may be and shall be carefully finished. Rounding or chamfering corners, arises junctions etc. shall be carried out with proper templates to the size required. Cement plaster shall be used within half an hour after addition of water. Any mortar or plaster which is partially set shall be rejected and removed forthwith from the size. In suspending the work at the end of the day, the plaster shall be left out clean to the line both horizontally and vertically. When recommending the plaster, the edges of the old work shall be scraped clean and wetted with cement putty before plaster is applied to the adjacent areas to enable the two to properly join together. Plastering work shall be closed at the end of the day on the body of the wall and nearer than 15 cm. To any corners or arises. Horizontal joints in plaster work shall not also occur on parapet tops and copings as these invariably load to leakage. No portion of the surface shall be left out initially to be packed up later on. Each coat shall be kept damp continuously till the next coat is applied or for a minimum period of 7 days. Moistening shall commence as soon as plaster is hardened sufficiently. Soaking of walls shall be avoided and only as much water as can be readily absorbed shall be used, excessive evaporation on the sunny or windward side of building in hot air or dry weather

shall be prevented by handing matting‟s or gunny bags on the outside of the plaster and keeping them wet.

Mode of measurements & payment: The rate shall include the cost of all materials, labour and scaffolding etc. Involved in the operations described under workmanship. All plastering shall be measured in square meters unless, otherwise specified, Length, breath or height shall be measured correct to a centimeter. Thickness of the plaster shall be exclusive of the thickness of the key i.e. Grooves or open joints in brick work, stone work etc. Or space between laths. Thickness of plaster shall be average thickness with minimum 10 mm. at any point on this surface. This item includes plastering up to floor two levels. The measurement of wall plastering shall be taken between the walls or partition (dimensions before plastering being taken) for length and from the top of floor or skirting to ceiling for height. Depth of cover of cornices if any shall be deducted. Soffits of stairs shall be measured as plastering on ceilings. Flowing soffits shall be measured separately.

No deductions shall be made for ends of joints, beams, posts etc. And openings not exceeding 0.5 sq.mt. Each and no addition shall be made for reveals, jambs, soffits, sills etc. Of these opening for finish to plaster around ends of joints, beams, posts etc. 2. Deduction for openings exceeding 0.5 sq.mt. But not exceeding 3 sq.mt. Each shall be made as follows and no addition shall be made for reveals, jambs, soffits, sills etc. Of these openings. a. When both faces of all walls are plastered with same plaster, deduction shall be made for one face only. b. When two faces of wall are plastered with different types of plaster or if one faces is plastered and the other pointed, deductions shall be made from the plaster or pointing on the side of frame for door, window etc. On which width of reveals is less than that on the other side but no deductions shall be made on the outer side. Where widths of reveals on both faces of wall are equal, deductions of 50% of area of opening on each face shall be made from area of plaster and/or pointing as the case may be. For openings having door frames equal to projecting beyond the thickness of wall, full deduction for opening shall be made from each plastered face of the wall. In case of openings of area above 3 sq.mt, each deduction shall be made for opening but jambs, soffits and sills shall be measured. The rate shall be for unit of one sq. Metre.
