It shall be the intent of these specifications to ensure that all concrete placed at various locations of the job should be durable, should wear and practically impervious to water. It should free from defects like cracking, honey combing etc. The Contractor under the Supervision of an Engineer shall carry out all concrete work. I.S. code under reference should mean the latest code together with amendments in circulations at the time of awards of the contract.

1.1 INGREDIENTS TO BE USED IN CONCRETE AND REINFORCED CONCRETE WORK : Ingredients to be used in concrete should confirm to the specifications as indicated under “Technical Specification for materials” gave earlier. As regards admixture, this may be used with prior approval of Architect / Management of OSIC

1.2 MIX PROPORTION: The mix proportions shall be selected to ensure that workability of the fresh concrete is

suitable for the conditions of handling and placing, so that after compaction it surrounds all reinforcements and completely fills the form.

The determination of the proportions of cement aggregates and water to attain the required strength shall be made as design mix as per IS-456-2000 considering factors like strength, durability, fire resistance etc.

1.3 MIXING:

Concrete shall be mixed in a mechanical mixer. The mixer should comply with I.S. 1791. The mixing shall be continuing until there is a uniform in color and consistency. If there is segregation after unloading from the mixer the concrete should be one and half to two minutes generally. In exceptional circumstances such a mechanical breakdown of mixer, or when the quantity of concrete is very small, hand mixing may be permitted, subject to adding 10% extra cement. When hand mixing is permitted, it should be carried out on a water tight platform and care shall be taken to ensure that mixing is continued until the concrete is uniform in color and consistency.

Workability of concrete should be controlled by direct measurement of water content and it should be checked at frequent intervals, of nominal mix workability measured by slump test may have the values given in Table A.

TABLE "A" Sl.No Type of work when vibrated 1. Mass concrete in R.C.C. 2.5cms. (1") Foundations footings retaining walls and road slabs. 2. Beams, slabs, columns 2.5 cms to 5 cms with simple reinforcement (1" to 2")

shall satisfy the specified strengths given in Table A, for the appropriate mix. As a guidance the difference between the maximum and the minimum strength of the three specimens shall not exceed 15% of the average strength. In case seven days result is not satisfactory all further work structurally interlinked with the concrete represented by the samples shall be stopped unless other wise decided by Engineer.

Twenty eight days test: Acceptance criteria of twenty eight days shall be as follows: a) If the average compressive strength of three cubes is more than the compressive

strength indicated in Table A, the concrete shall be accepted at full rates. b) If the average compressive strength of three cubes is less than the specified but

not less than 85% of the specified strength. the concrete may be accepted at reduced rate or prorate basis up to 80% of original rate of items.

c) If the average compressive strength of three cubes is less than 85% of the

specified strength, Architect/site Engineer shall reject and get dismantled and defective portion of the work represented by the sample along with the structurally connected work as considered necessary at the risk and cost of the Contractor. In case of (b) and (c) above, Architect/ Site Engineer, If he so decides may order the additional tests like fore test, ultrasonic test, rebound hammer test, load

63

test of structure of part of structure etc. to be carried out. All the charges in connection with these additional tests shall be borne by the contractor if on the basis of these additional tests the Architect / site Engineer is satisfied about the structural adequacy of the concrete, he may accept the work at reduced rates.

CONCRETE ORDERED TO BE DISMANTLED Where the Architect / Site Engineer does not accept the poor or defective concrete the contractor at his expense will dismantle the portion of structure and reconstruct the same to the Architect / Site Engineer's satisfaction. Concrete thus dismantled will not be measured and paid for. The additional work if and required to be carried out for re- concreting shall be to the contractor’s account. QUANTITY OF DEFECTIVE CONCRETE REPRESENTED BY CUBES In all cases of defective concrete as revealed by works test cubes strength failing below the specified strength. the quantity of concrete thus affected and represented by the cubes shall be decided by the Architect/Site Engineer whose decision shall be final and binding on the contractor.

b. The form work shall conform to the shape, lines and dimensions to suit the RCC

members as shown on drawings and to be so constructed. Form work shall be adequately designed to support the full weight of workers, fresh placed concrete without yielding settlement or deflection and to ensure good and truly aligned concrete finished in accordance with the construction drawings. A camber in all directions of 6mm for every 5m span in all slab and beam centering shall be given to allow for a unavoidable sagging due to compression or other causes.

c. The form work shall be so designed that the sides of the beams shall be first

struck leaving the soffit of beams and the supporting props in position. Props shall be designed to allow accurate adjustment and to permit of their being struck without jarring the concrete.

d. Temporary opening shall be provided at the base of column form and at other

points where necessary to facilitate cleaning and observation immediately before concrete is deposited.

e. Vertical shuttering : The vertical shuttering shall be carried down to such solid

surface as is sufficiently strong to afford adequate support and shall remain in position until the newly constructed work is about to support itself. Props shall be securely braced against lateral deflection. Where timber props are used like bullies, they shall be of a minimum diameter of 10cm. and shall be straight and adequately strong. The spacing of such struts shall be designed to carry loads imposed on it without undue deflection of the members supported by the props. The spacing of props shall be approved by the site Engineer and any alterations suggested by him shall be carried out at contractor's expense. Bracing shall be provided as directed without extra cost. Contractor shall allow in his rates providing props and struts for any height shown in the working drawings issued to contractor from time to time.

3.12 WATER TIGHTNESS:- It is the contractor's responsibility to ensure that the forms are checked for water tightness just before concreting operation starts and to make good any deficiencies. 3.13 CLEANING AND TREATMENT OF FORMS:- All rubbish, particularly chippings, shavings and sawdust shall be removed from the interior of the forms before the concrete is placed and the form work in contract with the concrete shall be cleaned and thoroughly wetted or treated with an approved

67

composition. Care shall be taken that such approved composition is kept out of contract with the reinforcement. 3.14 STRIPPING:- Forms shall left in place until their removal is authorized by the site Engineer and shall then be removed with care so as to avoid injury to concrete. In no circumstances shall forms be struck until the concrete reaches strength of at least twice the stress to which concrete may be subjected at the time of striking. The strength referred to shall be that of concrete using the same cement and aggregates with the same proportions, and cured under conditions of temperature and moisture similar to those existing on the work where possible, the form work shall be left longer, as it would assist the curing. 3.15 STRIPPING TIME:- In normal circumstances (generally where temperatures are above 20°C) and where ordinary cement is used , forms shall be struck after expiry of the following periods given in table VI. TABLE-VI ___________________________________________________________________

LOCATION Striking time in days for Ordinary pozzolana/ Portland cement . a. Vertical sides of walls, O- 24 Slabs, beams and columns b. Bottoms of slabs up to 4.5m span 7-14 c.

3.16 FORM WORK IN LIFTS FOR CONTINUOUS SURFACES: Where forms for continuous surface are placed in successive units (as for example in columns or walls), the forms shall fit tightly over the completed surfaces so as to prevent leakage or mortar from the concrete and do maintain accurate alignment of the surface. 3.17 PROCEDURE FOR REMOVING THE FORM WORK: All form work shall be removed without such shock or vibration as would damaged the reinforced concrete. Before the soffit and struts are removed, the

68

concrete surface shall be exposed where necessary in order to ascertains that the concrete has sufficiently hardened. Proper precautions shall be taken to allow for the decrease in the rate of hardening that occurs with all cements in the cold weather. For cantilevers props shall be removed from the tip towards support. Special notes given in relevant structural drawing shall be strictly adhered to in order of avoid mishaps. 3.18 TOLERANCES:

Sub-grade concrete or the R.C.C. slab on which the tiles are to be laid shall be cleaned, wetted and mopped. The bedding for the tile shall be with cement mortar 1:3 (1 cement : 3 coarse sand ) or as specified in the specification. The average thickness of the bedding shall be 20mm while the thickness under portion of the tiles shall not be less than 12mm.

Mortar shall be spread, temped and corrected to proper levels and allowed to harden sufficiently to offer a fairly rigid cushion for the tiles to be set to enable the mason to place wooden plank across and squat on it.

Over this mortar bedding neat grey cement slurry of honey like consistency shall be spread at the rate of 3.3 kg. of cement per square meter over such and area as soaked in water washed clean and shall be fixed in this grout one after another, each tiles gently being tapped with a wooden mallet till it is properly bedded and in level with the adjoining tiles. The joint shall be kept as thin as possible and in straight lines or to suit the required pattern.

The surface of flooring during laying shall be frequently checked with a straight edge about 2m long, so as to obtain a true surface with there required slops.

Where full size tiles cannot be fixed these shall be cut (Sawn) to the required size, and their edge rubbed smooth to ensure straight and true joints.

Tiles which are fixed in the floor adjoining the wall shall enter not less than 10mm. under plaster, skirting or dado.

After tiles have been laid surplus cement grout shall be cleaned off. Painting and Polishing: - The joints shall be cleaned off the grey cement grout with

wire brush or trowel to a depth of 2mm to 3mm and all dust and loose mortar removed. Joints shall then be flush pointed with white cement added with pigment if required to match the color of tiles. The floor shall be washed and finished clean. The finished floor shall not sound hollow when tapped with a wooden mallet.

3.0 CERAMIC TILES IN SKIRTING AND DADO:- 3.1 PREPARATION OF SURFACES:- The joints shall be raked out to a depth of at least 15mm in masonry walls, while the

masonry is being laid. In case of concrete walls, the surfaces shall be hipped and roughened with wire brushes. The surface shall be cleaned thoroughly, washed with water and kept wet before skirting work is commenced.

depth of 2mm to 3mm & all dust & loose removed. Joints shall then be flush pointed with white cement added with pigments if required to match the color of tiles. The surfaces shall then be kept wet for seven days. After curing the surface shall be washed and finished clean. The finished work shall not sound hollow when tapped with a wooden mallet.

4.0 ARTIFICIAL STONE FLORING:

Selection of materials, methods of mixing, placing and compacting shall generally conform to the specification under plain and reinforced cement concrete described earlier. A stiff mix consistent with workability shall be used.

4.1 PREPARATION OF SURFACE: Before the operation for laying topping is started the surface of base concrete shall be

thoroughly cleaned of all dirt, loose particles, caked mortar, droppings and laitance of any by scrubbing with coir or steel wire brush where the concrete has hardened so much that roughening of surface by wire brush is not possible, the surface shall be roughened by chipping or hacking at close intervals. The surface shall then be cleaned with water & kept for 12 hours and surplus water shall be removed by mopping before the topping is laid.

4.2 LAYING: The screed strips shall be fixed over the base concrete dividing it into suitable panels.

Before placing the concrete for topping, neat cement slurry shall be thoroughly brushed into the prepared surface of the base concrete just ahead of the finish. Concrete of specified proportion and thickness shall be laid in alternate panels to required level and shape and thoroughly tamped.

4.3 FINISHING THE SURFACE: After the concrete has been fully compacted it shall be finished by toweling or floating

with neat cement rendering Finishing operations shall start shortly after the compaction of concrete and the surfaces shall be trowel led three times at intervals so as to produce a uniform and hard surface. The satisfactory resistance of floor to wear depends largely upon the care with trowelling is carried out. The time interval allowed between successive trowelling is very important. Immediately trowelling shall be done to give a level surface. Excessive trowelling in the earlier stages shall be avoided as this tends to bring a layer rich in cement to line surface. Sometime after the first trowelling, the duration depending upon the temperature, atmospheric conditions and the of cement used, the surface shall be retrowelled to close any pores in the surface and to bring to surface shall be retrowelled to close any pores in the surface and to bring to surface and

74

to scrap off any excess water in concrete or laitance. No dry cement shall be used directly on the surface to absorb moistures or to stiffen the mix. The final trowelling shall be done well before the concrete has become too hard but at such a time that considerable pressure is required to make any impression on the surface if directly by the Architect approved minerals pigment shall be added to the rendering to give desired color and shade to the flooring at no extra cost.

5.0 MARBLE STONE FLOORING: 5.1 DRESSING OF SLABS: Every stone shall be hand/machine cut to the required size and shape, fine chisel

In the case of old work, all loose pieces and scales, shall be cleaned of all dirt, dust, algae, oil etc. by brushing and washing. pitting in plaster shall be made good and coat of water proof cement paint shall be applied over patches after wetting them thoroughly.

77

2.2 PREPARATION OF MIX: Cement paint shall be mixed in such quantities as can be used up within an

hour of its mixing as otherwise the mixture will set & thicken, affecting flow and finish.

Cement paint shall be mixed with water in two stages. The first stage comprise of 2 parts of cement paint and 1 part of water stained thoroughly and allowed to stand for five minutes. Care should be taken to add the cement paint gradually to the water and not vice- versa. The second stage shall comprise of adding further one part of water to the mix and stirring thoroughly to obtain a liquid of workable and uniform consistency. In all cases the manufacturer’s instructions shall be followed meticulously.

The lids of cement paint drums shall be kept tightly closed when not in use, as by exposure to atmosphere the cement paint rapidly becomes air set due to its hygroscopic qualities.

The solution shall be applied on the clean and wetted surface with brushes or spraying machine. The solution shall be kept well stirred during the period of application. It shall be applied on the surface which is on the shady side of the building so that the direct heat of the sun of the surface is avoided. The method of apply of the second or subsequent coats, the surface of the specification. The completed surface shall be watered after the day's work.

The second coat shall be applied after the first coat has been set for at least 24 hours. Before application of the second or subsequent coats, the surface of the previous coat shall not be wetted.

For new work, the surface shall be painted with three or more coats of water proof cement paint as found necessary to get a uniform shade.

For old work, the treatment shall be with one or more coats as found necessary to get a uniform shade.

3.2 PREPARATION OF SURFACE: The surface shall be thoroughly cleaned and dusted. All rust, dirt, scales, smoke and

grease shall be thoroughly removed before painting is started. The prepared surface shall have received the approval of the Architect /Management of OSIC after inspection, before painting is commenced.

3.3 APPLICATION: Before pouring into smaller container for use, the paint shall be stirred

thoroughly in the containers. When applying also, the paint shall be continuously stirred in the smaller container so that its consistency is kept uniform.

If for any reasons , thinning is necessary in case of ready mixed paint, the brand of thinner recommended by the manufacturer or as instructed by the Architects/ Management shall be used.

The painting shall be laid on evenly and smoothly by means of crossing and smoothly by means of crossing and laying off , the latter in the direction of the grain of wood. The crossing & laying of consists of covering the area over with paint, brushing the surface hard for the first time over and ten brushing alternately in opposite direction, two or three times and then finally brushing lightly in a direction at right angles to the same. In this process, no brush marks shall be left after laying off is finished. The full process of crossing and laying off will constitute one coat. Where so stipulated the painting shall be done by spraying. Spray machine used may be (a) high pressure (small air aperture) type (b) a low pressure (large air aperture) type , depending on the nature and location of work to be carried out. Skilled and experienced workmen shall be employed for this class of work. Paints used shall be brought to the requisite consistency by adding a suitable thinner.

Spraying should be done only when dry condition prevails. Each coat shall be allowed to dry thoroughly and rubbed smooth before the next coat is applied. This should be facilitated by through ventilation. Each coat except the last coat shall be lightly rubbed with sand paper or with pumice stone and cleaned off dust before the next coat is laid.

No left over paint shall be put back into the stock tins. When not in use the container shall be kept properly closed.

No hair marks from the brush or clogging of paint puddles in the corners of panes, angles of moldings etc., shall be left on the work.

In painting doors and windows, the putty round, the glass panes must also be painted, but care must be taken to see that no paint stains etc. are left on the glass top of shutters and surfaces in similar hidden location shall not be left out in paint.

In painting steel work, special care shall be taken while painting over bolts, nuts, rivets, overlaps etc.

The additional specifications for primer & other coats of paints shall be as according to the detailed specifications under the respective headings.
