Placing of Reinforcement:

All reinforcing bars shall be accurately placed in the exact position shown on the drawings/as per instructed by

Eng In-charge, and shall be securely held in position during placing of concrete by annealed binding wire not

less than 1 mm in size and conforming to IS:280 and by using stays blocks or metal chairs, spacer, metal

hangers, supporting wires or other approved devices at sufficiently close intervals. Bars will not be allowed to

sag between supports nor displaced during concreting or any other operation over the work. All devices used for

positioning shall be of non-corrodible material. Wooden and metal supports will not extend to the surface of

concrete, except where shown on the drawings, placing bars on layers of freshly laid concrete as the work

progresses for adjusting bar spacing will not be allowed. Pieces of broken stone, brick or wooden blocks shall

not be used. Layers of bars shall be separated by spacer bars, precast mortar blocks or other approved devices.

Reinforcement after being placed in position shall be maintained in a clean condition until completely

embedded in concrete. Special care shall be exercised to prevent any displacement of reinforcement in concrete

already placed.

To protect reinforcement from corrosion, concrete cover shall be provided as indicated on the drawings/as per

instructed by Eng In-charge. All bars protruding from concrete to which other bars are to be spliced and which

are likely to be exposed for an indefinite period shall be protected by a thick coat of neat cement grout.

Bars crossing each other, where required, shall be secured by binding wire (annealed) of size not less than 1 mm

and conforming to IS:280 in such a manner that they do not slip over each other at the time of fixing and

concreting. As far as possible, bars of full length shall be used. In case this is not possible, overlapping of bars

shall be done as directed by the Eng In-charge, AMC, Ahmedabad. When practicable, overlapping bars shall not

touch each other, but be kept apart by 25 mm or 1 ¼ times the maximum size of the coarse aggregates

whichever is greater, by concrete between them. Where this is not feasible, overlapping bars shall be bound

with annealed steel wire, not less than [1 mm thickness twisted tight in eight shape around the lapped bars. The

overlaps shall be staggered for different bars and located at fixed locations only along the span where neither

shear nor being moment is maximum.

Welding of Bars

reinforcement bars shall be butt welded so as to transit their full strength. Welded joints shall preferably be

located at points where steel will not be subject to more than 75 percent of the maximum permissible stresses

and welds so staggered that at any one section, not more than 33 per cent of the rods are welded. No –pre-

warning or post heat treatment is necessary. Interpass temperature should be limited to 200º C with low heat

input and equivalent strength low hydrogen type electrode. Suitable means shall be provided for holding the

bars securely in position during welding. It must be ensured that no voids are left in welding and when welding

is done in 2 or 3 stages, previous surface shall be cleaned property. Ends of the bars shall be cleaned of all loose

scale, rust, grease, paint and other foreign matter before welding. Only competent welders shall be employed on

AhmedabadMunicipalCorporation

All concrete mix design shall meet the requirements of TRIMIX concrete mix design recommendations.

Execution Tremix System

The work shall be planned and executed so that there is no delay between the placement, screeding, dewatering and

floating of the concrete. Concrete to be vacuum dewatered shall be handled and placed so as to prevent segregation.

The concrete shall be internally vibrated prior to screeding.

Immediately following placement, the concrete shall be levelled with a vibrating screeding running on a true surface, set

at the proper elevation required to provide the specified finished elevation. The concrete surface shall be screeded high

by 2% of the slab's thickness to compensation for the compaction caused by the vacuum dewatering process. (Slabs to

have an aggregate hardener shall have compensation made to maintain elevation). The vibrating screed shall be moved

forward as rapidly as proper consolidation allows. The proper surcharge of concrete must be maintained in front of the

leading edge of the screed.

Immediately after levelling, the concrete shall be covered with filter pads and suction mats in strict accordance with the

recommendation of the manufacturer to have the slab fully dewatered. The suction mat shall extend 4 inches beyond

the edge of the filter pad on all sides. The pads shall extend to within 4" of the edge of concrete slab, and the mats shall

cover entire slab. Before connecting the hose on the suction mat to the vacuum pump, the edges of the mat shall be

smoothed to enable an airtight seal to be created. A vacuum shall then be applied to the mat. After a minute the gauge

on the vacuum pump should indicate a minimum vacuum of 0.70 atmospheres (24.0 in. Hg) and if not, the mat must be

checked for leakage. For concrete that dewaters readily the vacuum should then be maintained awt 0.70-0.80

atmospheres (24.0-25.5 in. Hg.) For concrete which dewaters less efficiently (e.g. air-entrained concrete) the vacuum

shall then be reduced to 0.50-0.60 atmospheres (15.0-18.0 in. Hg). After approximately 10 minutes the vacuum can then

be increased to 0.80 atmospheres.

The vacuum shall be maintained for at least 3 minutes per inch of concrete thickness at 0.80 atmospheres. (Where

aggregate hardeners are specified, sufficient moisture shall be maintained to meet manufacturer's requirements). The

suction mats and filter pads shall then be removed and moved to the next section in leapfrog manner.

Stop the vacuum dewatering when light footprints only are left in the concrete when stepped upon.

Floating: Upon removal of the suction mats and filter pads the concrete surface shall be power-floated without delay

until all imprints from the vacuum process are removed. If crusting occurs, the floating operation must be delayed till

the concrete carries the machine.

The higher speed is recommended for the floading operation. Two passes with the floating disc should be made in the

junction of two mats in order to avoid risk for cracking.

The waiting time after the floating operation depends on concrete temperature and humidity and varies from

minutes to 2 hours.

The trowelling operation cannot take place before the concrete has hardened enough to carry the machine, i.e. the

trowelling blades will not leave any marks on the concrete. Repeated trowelling with intervals between the passes,

SignatureofBidder Page100of228

which are adapted to the setting of the concrete, greatly improves the surface characteristics. The surface will be more

wear resistant and less dusty.

Vacuum dewatered concrete should be cured like any other quality concrete in order to achieve good final result with

charge. The water cement ratios shall not be more than those specified as per IS. The cement of the

mix 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.

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 a nominal size of 20 mm. are generally

considered satisfactory. Admixture shall 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 of concrete impaired by the use of such

admixtures. 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 m3.

Boxes of suitable sizes shall be used for measuring sand and aggregate. The size of the boxes

(internal) shall be 30cm. x 30 cm. and 38 cm. 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. 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 maintained throughout the construction. 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 -

42 - 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. 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. 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 slump tests in accordance with IS : 1199-1959. The slump of 10 mm. to

Signature of Bidder Page 19 of

Ahmedabad Municipal Corporation

25 mm. shall be adopted when vibrators are used. Inspection : All Moulds shall be cleaned and made

free from standing water, dust, snow or ice immediately before placing of concrete. Formwork/Metal

Mould for exposed concrete surface (If indicated): All the moulds shall be checked for exact

dimensions of the Precast blocks. All the edges of the Precast blocks shall confirm the profile of the

final drawing & edges/ curvatures of the moulds shall be checked accordingly. Moulds shall be

regularly checked for correctness of dimensions of Blocks, twists, bends due to handling, etc.. before

starting every days work. Care shall be taken to set all formwork/Mould in perfect line, level (or in

required camber or slope as specified) and plumb. Formwork/Mould propping shall be strong, rigid and

sturdy. The formwork/Mould shall be as per pattern & design shown in drawings. Formwork/Mould

shall be done accurately and precisely so as to achieve neat, clean and smooth concrete surface, in

line, level and plumb. Clinks, twists, offsets, warps, riveting etc. in plates or forms shall not be allowed.

Before placing concrete, forms shall be thoroughly cleaned off of all rust, dust and loose materials.

Colorless oil or grease of approved quality shall be applied before placing steel. Also the formwork

material will be of wood/plywood/steel or any sort of such material, as approved by the Engineer in

charge, so that all exposed concrete surfaces have uniform colour. For all kind of exposed concrete

work only one brand (to be approved by the Engineer-in charge)of cement shall be used. Removal of

Moulds: Specific time shall be identified for removal of moulds, such that the concrete of the Precast

blocks shall gain strength to withstand the stresses generated due to self weight and handling to

drying yards without any deformation to shape/ dimensions/ edges. Drying Period: Sufficient time shall

be given to the block after it is removed from the mould so that it can gain strength and dry in shade to

prevent any cracks due to shrinkage. This shall be done in drying yards. Curing Period: Curing of block

shall be done only in curing pond and curing shall be done for minimum 14 days. Drying period after

removing from pond & before delivery to site: Water should be drained of from the block before it is

actually sent to the site. Time should be provided for proper draining of water which may be present in

the block kept for curing in the pond. Precautions: Precaution shall be taken while transporting of the

blocks to site. The blocks should be loaded and unloaded with due care so as to avoid generation of

stresses leading to breaking of block. Care should be taken to prevent the block from breaking during

transporting. - 43 - Fixing: The pits of the size 0.15 M in width and required depth shall first be

excavated, true to line and level. The relevant specifications of item A- 1 shall be followed for

excavation work. The pits shall be filled with a layer of 0.05 M. thick sand bedding. The curbs then

shall be placed in position of which 50mm. shall be below road. Care should be taken to maintain

proper line and level. The joints between the kerbs shall be pointed with C.M. 1:2 and cured for

minimum seven days. Sampling and testing of concrete: Samples from fresh concrete shall be taken

as per IS : 1199-1959 and cubes shall be made, cured and tested at 7 days or 28 days as per

requirements in accordance with IS : 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. NOTE: At least

sample shall be taken from each shift. Ten test specimens shall be made from each sample, 5 for

testing at 7 days and the remaining 5 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 cast for

each day shall not be less than the specified cube strength of 200 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. 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. Precast Kerb Stones : The relevant

Signature of Bidder Page 20 of

specifications of concreting as per item above shall be followed except that work shall be carried out

for precast concrete kerb stones as specified in the item. All Precast members shall be cast at

workshop. Sufficient curing shall be done before placement of the same The method of transporting

and placing the precast members shall be as approved by the Engineer-in-charge. Members shall be

so transported that no breakage or undue stresses are induced in them. If required, all members shall

have a key provided on both the faces i.e. top and bottom surfaces, of adequate size so as to fill the

same with concrete while laying. The function of this key is to avoid the leakage through the joint

between the precast member and the member on which it is laid. Mode of Measurements and

Payment : The rate shall include cost of formwork but exclude the cost of reinforcement. The volume

occupied by reinforcement shall not be deducted from R.C.C. work. Mode of measurements and

payment: The rate shall be for a unit of Rmt.
