General: Cement concrete including cost of formwork, Shoring, strutting & dewatering if require etc.

No extra payment will be made for shoring, strutting and dewatering. Before commencing the

concreting, the depth and width of the excavated foundation shall be checked as per the drawing. The

bed of foundation trenches shall be cleared off of all loose materials, levelled, watered and rammed, as

directed. The concrete mix is not required to be designed by preliminary tests and only nominal mix as

per IS: 456-2000 shall be followed. The proportion of the concrete mix shall be 1:2:4 (1 cement:

coarse sand: 4 graded Black trap stone aggregate 20 mm. nominal size) by volume. All Concrete work

shall have fair finished concrete surface unless otherwise specified. Mix design shall be carried out for

environmental exposure condition as given in IS 456:2000 page 18 table 3. The nominal mix concrete

shall only be used for concrete grade lower than M15. The ingredients required for ordinary concrete

containing one bag of cement of 50 Kg. by weight (0.0347 m3.) for different proportions of mix shall be

as under: (as per IS 456:2000 Table 9 pg. 23)

Grade of Total Qty. of Dry aggregate by mass Proportion of fine Qty. of water per

Concrete per 50 kg of cement to be taken as aggregate to coarse 50kg of Cement,

the sum of individual mass of fine aggregate (Maximum) liters

and Coarse aggregate, (Maximum)

M 10 ( 1:3:6 ) 480 Generally 1:2 for FA

to CA by volume but

subject to upper limit

of 1:1.5 and lower

The proportion of the fine to coarse aggregates shall be adjusted from upper limit to lower limit

progressively as the grading of fine aggregates becomes finer and the maximum size of coarse

aggregate becomes larger. Graded coarse aggregate shall be used. For an average grading of fine

aggregate (Zone II of table 4 of IS 383), the proportions shall be 1:1.5, 1:2 and 1:2.5 for the maximum

size of aggregates 10mm, 20mm and 40mm respectively. The water cement ratios shall not be more

than those specified in the above table. The cement of the mix specified in the table shall be

proportionately 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. The 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 1/4th 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

maximum 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. Coarse and fine aggregate

shall be batched separately. All in aggregate may be use if specified by Engineer-in-charge. Admixture

(chloride free) may be used in concrete only with approval of the Engineer-in-charge based upon the

evidence that with the passage of time, neither the compressive strength of concrete is reduced nor

are other requisite qualities ofconcrete and steel impaired by the use of such admixtures. The cost of

the formwork shall be included. For hot and cold weather precautions to be taken are as follow:

Temperature of coarse aggregate shall be maintained as per IS specifications by use of Ice Flakes for

mass concrete. In hot weather, ice flakes shall be added in the concrete or aggregate shall be kept cool

by sprinkling water. Necessary corrections shall be performed in the mix design of the concrete. Coarse

aggregate shall be stored under shed in case of hot weather temperature. Avoid concreting in the

noontime in case of hot weather and during night time in case of Cold weather. In hot weather, the

formwork shall be sprinkled with water before commencing the concrete work.

Proportioning shall be done by volume, except cement which shall be measured in terms of bags of

Kg. weight. The volume of one such bag being taken as 0.0347 m3. Boxes of suitable sizes shall be used

for measuring sand and aggregate. The size of the boxes (internal) shall be 30 cm. x 30 cm. and 38 cm.

deep or as per the convenience of the contractor. The Internal volume of the box shall be taken as

0.0347 m3. 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 bulkage shall be made.

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 maintained throughout the construction. The mixer shall

comply with IS 1791 and IS 12119. Measured quantity of aggregate, sand and 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 colour 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 a smooth watertight platform large enough

to allow efficient turning over the ingredients of concrete before and after adding water. Mixing

platforms shall be so arranged that no foreign material 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. Dry coarse and fine aggregate and cement shall then be mixed

thoroughly by turning over to get a mixture of uniform colour. 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 % above that specified. 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 2/3rds of normal quantity of coarse aggregate. Mixing

plant shall be thoroughly cleaned before changing from one type of cement to another.

The degree of consistency which shall depend upon the nature of the work and methods of vibration of

concrete, shall be determined by regular slump tests in accordance with IS : 1199-1959. The slump of

10 mm. to 25 mm. shall be maintained for workability. The concrete shall be compacted with vibrator -

needle or surface type depending on the nature of application.

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 relieve 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. Contractor shall proper access with railing for inspection of work. centring 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 labour and other persons

shall be totally prohibited after reinforcement is 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/ PVC cover of suitable size and thickness as per the drawing shall be tied to

the reinforcement. Timber, kapachi or stone pieces shall not be used for this purpose. For exposed

concrete members PVC blocks of grey colour shall only be used. All formwork shall be cleaned and

made free from standing water, dust, snow 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

The shuttering to be provided shall be of ordinary timber planks shall conform to M-26A. Shuttering

plywood shall conform to M-26B.The dimensions of scantling and battens shall conform to the design.

The strength of the wood shall not be less than that assumed in the design.

For concrete shuttering material shall be as follows:

Moulds from marine ply with wooden battens or steel plates

Straight walls / Curved wall in plan :

Marine plywood with wooden battens / Acro make or equivalent makes steel plates and soldiers.

Steel plates and marine ply with battens

The form work shall conform to the shape, lines and dimensions as shown on the drawings and shall be

so constructed so as to remain sufficiently rigid and water-tight, during the placement and compaction

of the concrete. Adequate arrangement shall be made by the Contractor to safe guard against any

settlement of the form work during the course of concreting and after concreting. The form work of

shuttering, centring, scaffolding, bracing, etc. shall be as per the design. Cleaning & Treatment of

Forms: All rubbish, particularly chipping, shaving and saw dust shall be removed from the interior of the

form before the concrete is placed and the form work in contact with concrete shall be cleaned and

thoroughly wetted or treated. The surface shall be coated with soap solution, applied before concreting

is done. Soap solution for the oil or from oil of approved manufacture may be applied, in case steel

shuttering is used. Care shall be taken that the coating is not applied on the construction joints surface

and steel reinforcement bars.

In normal circumstances and where ordinary Portland cement is used, form work may be struck after

expiry of the following periods:(a) Sides of walls columns and vertical faces of beams 24 to 48 hours.

(b)Beam soffits (Props left under) 7 days. (c)Removal of props for slabs - (i) Slabs spanning up to 4.5 m.

7 days. (ii) Slabs spanning over 4.5 m. 14 days. (d)Removal of props to beams and Arches (i) Spanning

up to 6 m. 14 days. (ii) Spanning over 6 m. 21 Days.

The Engineer-in-charge shall be informed in advance by the Contractor of his intention to strike the

formwork. While fixing the time for removal of formwork, 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 temperature is

above 20Degree) and where ordinary concrete is used, forms may be struck after expiry of periods

specified in IS 456:2000 11.3.1 page 25 for respective item of formwork or mentioned above. All

formwork shall be removed without causing any shock or vibration as would damage the concrete.

Before the soffit and struts are removed, the concrete surface shall be gradually exposed, where

necessary in order to ascertain that the concrete has sufficiently hardened. centring shall be gradually

and uniformly lowered in such manner as to permit the concrete to take stress 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 covers 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 removal of formwork and shuttering the Engineer-in-charge shall inspect

the work and satisfy by random checks that concrete produced is of good quality. The number of props

left under, their sizes and disposition shall be such as to be able to safely carry the full load of the slab,

beam or arch as the case may be together with any live load likely to occur during curing or further

construction. Immediately after the removal of forms, all exposed bolts etc. passing through the

cement concrete member and used for shuttering or any other purpose shall be cut inside the cement

concrete member to a depth of at least 25 mm. below the surface of the concrete and the resulting

holes are filled by cement mortar. All fine mortar lines caused by form joints, all cavities produced by

the removal of form 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 sand. Considerable pressure shall be applied in filling and

pointing to ensure thorough filling in all voids. Surfaces, which are pointed, shall be kept moist for a

period of 24 hours. For repairing concrete members, suitable bonding agent shall be used as directed

by the consultant. If rock pockets/honeycombs in the opinion of Engineer-in-charge are of such an

extent or character so as to effect 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 portion of the structure affected with no extra cost

The centring to be provided shall be got approved. It shall be sufficiently strong to ensure absolute

safety of the form work and concrete work before, during and after pouring concrete. Carpenter and

helper shall be invariably be kept present to watch the behaviour of centring and form work is

satisfactory during concreting. 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. The props of

centring shall be provided on firm foundation or base of sufficient strength to carry the loads, without

any settlement. The centring and form work shall be inspected and approved by the Engineer-in-

charge, before concreting. But this will not relieve the Contractor of his responsibility for strength,

adequacy and safety of form work and centring. If there is a failure of form work or centring, the

Contractor shall be responsible for the damages to the work, injury to life and damage to property.

Scaffolding and staging:

All scaffolding, hoisting arrangements and ladders, etc. required for facilitating of concreting shall be

provided and removed on completion work by Contractor, at his own expense. The scaffolding, hoisting

arrangement, ladders etc. shall be strong enough to withstand all live, dead and impact loads expected

to act and shall be subject to the approval of the Architect and Engineer-in-charge. However,

Contractor shall be solely responsible for the safety of the scaffolding, hoisting arrangement, ladders,

work and workmen, etc. The scaffolding, hoisting arrangements and ladders shall allow easy approach

to the work spot and afford easy inspection.

Before re-use, all forms shall be inspected by the Engineer-in-charge and their suitability shall be

ascertained. If, any of the forms are found to be unsuitable, they shall be immediately removed from

the site. The forms ascertained for re-use, shall be scarred, cleaned, and joints gone over and repaired,

wherever required. The inside surface shall be retreated to prevent adhesion to concrete.

Transportation, laying and compaction:

The method of RMC transporting and placing concrete shall be as approved by Engineer-in-charge.

Concrete shall be so transported and placed that no contamination, segregation or loss of its

constituent material takes place. Concreting 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 joint 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 in horizontal layers to a compacted depth of not

more than 0.45 m. when internal vibrators are used and not exceeding 0.3 m. 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 m. when trucking or chutes are used they shall be kept closed and used in such a way so 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 dislodgment of any particles or 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 this 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 needle or surface

vibrators/ iron rammer, unless otherwise, permitted by the Engineer-in-charge for exceptional case,

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, as it tends to destroy the

bond between concrete and reinforcement.

Sampling and testing of concrete:

The contractor shall set up a site laboratory to carry out various tests as specified. The laboratory shall

include equipment like cube testing machine, slump cone, cube molds for concrete and mortar,

mechanical balance, sieve set, flakiness testing apparatus, core cutter etc.

Samples from fresh concrete shall be taken as per IS: 1199 and cubes shall be made, cured and tested

at 7 days or 28 days as per requirements in accordance with IS : 516. 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 Work Nos of Sample of Concrete for testing of 28 days

51 M3and Above 4 Plus One Additional for each 50 M3or part thereof

NOTE: At least 1 sample shall be taken from each shift. Three test specimens shall be made for each

sample for testing at 28 days. Additional samples must be taken to determine strength at 7 or 3 days or

at the time of striking the formwork, or to determine the duration of curing, or to check the testing

error. 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

test results of the sample shall be average of the strength of 3 specimens. The individual variation shall

not be 15% of the average strength of the sample. The compressive mean strength for the group of

non-overlapping consecutive test results shall be as per col. 2 table 11 of IS 456:2000 and individual

test results shall be as per col. 3 of table 11 of IS 456:2000.

Mode of Measurements and Payment:

RMC Cement concrete delivered at site should be workable and should satisfy all the required standard

tests like cube test and slump test etc., as specified in code of practice. Samples taken at site only will

be deciding factor. Department will not have any direct contact in matters relating to payment, delivery

schedule, quality of concrete etc. It is the responsibility of contractor ensures proper co-ordination for

the timely supply of concrete and approved quality product. Contractor has to make arrangement for

proper approach road (for which nothing extra shall be paid for) to enable the vehicle carrying concrete

to move freely without any extra cost to the department before ordering the concrete. However

existing approach road may be made use of for this purpose. Contractor has to ensure proper strong

shuttering / centring to receive the concrete at all heights. Contractor has to indemnify the department

arising out of possible dispute with the manufacturers. The design mix of RMC for the manufacturer /

supplier of RMC has to be obtained well in time and approval of Engineer in Charge to be obtained

prior to use. The design mix should be based on latest IS 456. This approval has to be obtained

whenever the design mix is changed. The RMC should be supplied confirming to the approved design

mix which shall be continuously checked during the progress of work. All the quality checks as per IS

stipulations should be scrupulously followed during the concreting. The work shall be carried out at all

heights as shown in Bill of Quantities. The relevant specifications of item no 06 shall be followed except

that the concrete mix shall be designed from preliminary tests the proportioning of cement and

aggregates shall be done by weight and necessary precautions shall be taken in the production to

ensure that the required work cube strength is attained and maintained. The letter "M" refers to mix

and numbers specify 28 days’ works cube compressive strength of 150 mm. cubes of the mix expressed

in accordance with the requirements of IS: 456:2000. The concrete shall be designed as per relevant

latest IS code- IS 10262 and SP 23, with or without chemical admixture to provide the grade of concrete

having required workability and characteristic strength as per IS 456:2000. The proportion of cement,

sand and coarse aggregates shall be determined by weight. The weight batch machine shall be used for

maintaining proper control over the proportion of aggregates as per mix design. The design mix shall be

got approved by Engineer in-charge before starting the concrete work. The minimum cement content

shall depend on the exposure condition of the concrete. The minimum cement content given in table

(IS 456:2000, table 5) shall be adopted irrespective of whether the contractor achieves the desired

strength with less quantity of cement. The strength requirements of different grades of concrete shall

In all cases, the 28 days compressive strength specified in above table be the criteria for acceptance or

rejection of the concrete. Where the strength of a concrete mix as indicated by tests, lies in between

the strength of any two grades specified in the above table, such concrete shall be classified in for all

purposes as concrete belonging to the lower of the two grades between which its strength lies. The

Contractor shall take necessary care to avoid sand streaks, air holes, honey combining etc., on finished

concrete surface.

Basis of Supply:

Depending upon the agreement the ready mix concrete shall be supplied on either of the following

basis: a) Specified strength based on 28-day compressive strength of 15cm cubes tested in accordance

with IS: 456-2000.b) Specified mix proportion.

When the concrete is manufactured and supplied on the basis of specified strength, the responsibility

for the design of mix shall be that of the contractor and the concrete shall confirm to the requirements

specified. Mixing, consistency, inspection, transportation and laying, formwork for concrete: These

shall be same as per Item No:06

General Requirements:

The minimum cement content for the various mixes shall be 475 Kg/cum or as per Mix Design

whichever is higher and the details regarding proportioning and works control shall be in accordance

with IS: 456:2000 or our specification stated. When a transit mixer is used for transportation of

concrete, no extra water should be added to the concrete from elsewhere after initial introduction of

mixing water from the batch, except when on arrival at the site of the work, the slump of the concrete

is less than that specified: such additional water to bring the slump within required limits shall be

injected into that specified: such additional water to bring the mixer under such pressure and direction

of flow that requirements for uniformity are met. When a transit mixer is used for transporting

concrete, the concrete shall be delivered to the site of the work and discharge shall be complete within

one and half hour (when the prevailing atmospheric temperature is at or below 20 degree Celsius) of

adding the mixing water to the dry mix of cement and aggregate or of adding the cement to the

aggregate whichever is earlier. The compressive strength and slump test shall be performed by third

party or outside laboratory is required. It is most important to keep the specified water cement ratio

constant and at its correct value. To this end, moisture content in both fine and coarse aggregates shall

be determined by the Engineer-in-charge, according to the weather conditions. The amount of mixing

water shall then be adjusted to compensate for variations in the moisture content. For the

determination of moisture content in the aggregates, IS: 2386 (Part III) shall be referred to. Suitable

adjustments shall also be made in the weights of aggregates due to variation in their moisture content.

The bars shall be kept in position by the following methods:

In case of beam, slab, wall and column, sufficient number of PVC block or precast cover block in cement

mortar 1:2 (1 cement: 2 coarse sand) about 4 cm. x 4 cm. round or square section and of thickness

equal to as specified in the drawing shall be placed between the bar and shuttering to maintain the

requisite cover in the concrete member. In case of cantilevered or doubly reinforced beams/slabs, the

top main reinforcing bars shall be held in position by introducing chair of appropriate bar spacers or

supports bar at 1.0 to 1.2 m. centers. In case of columns and walls, the vertical bars shall be kept at the

top of the mould in position by means of timber/steel templates with slots accurately cutout in them.

The templates shall be removed after concreting has been done below it. The bars may also be suitably

tied by means of annealed GI wires to the shuttering to maintain their position during concreting. The

GI wire shall be tied in such a way that they shall not get embedded in the concrete. The bars shall be

tied with GI binding wires as per the instructions given by Engineer-in-charge.

The temperature of the concrete at the place and time of delivery shall not less than 5-degree Celsius

above the prevailing shade temperature is less than 2.5 degree Celsius and the thermometer reading is

foreign matter by water or by brushing. Smooth surface should be roughened by wire brush, racking of

joints, hacking on concrete structure, trimming of projection on brick / concrete block / concrete

surface where necessary shall be carried out to get an even surface. Surface should be damped (not

soaked) evenly before applying the plaster. If the surface becomes dry such area shall be moisturized

Application of Plaster:

1 - The plaster about 15cm x 15 cm shall be applied horizontally and vertically not more than 2 Meters

intervals over the entire surface to serve as gauge. The surface of these shall be truly in plane of the

finished plastered surface. The mortar shall then apply in uniform surface slightly more than the

specified thickness. Then brought to a true surface by working a wooden / aluminium straight edge

reaching across the gauges with small upward and sideways movement at a item. Finally the surface

shall be finished off true with trowel or wooden float accordingly as a smooth or a sandy granular

texture is required. Excessive troweling or overworking the float shall be avoided. All corners arise,

angles and junctions be truly vertical or horizontal as the case may be and shall be carefully finished.

Rounding or chamfering corners arises junction etc. shall be carried out with proper templets to the
