BATCHING AND MIXING CONCRETE

Based on the adopted nominal mixes, aggregates and cement shall be measured by weight.

PREPARATION PRIOR TO CONCRETE PLACEMENT

Signature of Bidder Page 52 of

Ahmedabad Municipal Corporation

Before concrete is actually placed in position, the inside of the form work shall be cleaned and mould oil

applied, inserts and reinforcement shall be correctly positioned and securely held, necessary openings

pockets etc. provided.

All arrangements formwork, equipment and proposed procedure, shall be approved by Engineer. The

Contractor shall maintain separate Pour Card for each pour as per the format enclosed and shall produce

before commencement of concreting to Engineer-in-charge.

TRANSPORTING, PLACING AND COMPACTING CONCRETE

Concrete shall be transported from the mixing plant to the formwork with minimum time lapse by

methods that shall maintain the required workability and will prevent segregation, loss of any ingredients

or ingress of foreign matter or water.

In all cases concrete shall be deposited as early as practicable directly in its final position. To avoid

segregation concrete shall not be re-handled or caused to flow. For locations where direct placement is

not possible and in narrow forms. The Contractor shall provide suitable drops and “Elephant Trunks”

Concrete shall not be dropped from a height of more than 1.0 mm as stipulated in clause D.6.8.13.

Concrete shall not be placed in flowing water. Under water, concrete shall be placed in position by

tremies or by pipeline from the mixer and shall never be allowed to fall freely through the water. While

placing concrete the Contractor shall proposed as specified below and also ensure the following:

a) Continuously between construction joints and predetermined abutments.

b) Without disturbance to forms or reinforcement.

c) Without disturbance to pipes, ducts, fixings and the like to be cast in; ensure that such items are

securely fixed. Ensure that concrete cannot enter open ends of pipes and conduits etc.

d) Without dropping in a manner that could cause segregation or shock.

e) In deep pours only when the concrete and framework designed for this purpose and by using suitable

chutes or pipes.

f) Do not place if the workability is such that full compaction cannot be achieved.

g) Without disturbing the unsupported sides of excavations; prevent contamination of concrete with

earth. Provide sheeting if necessary. In supported excavations, withdraw the lining progressively as

concrete is placed.

h) If placed directly on to hardcore or any other porous material, dampen the surface to reduce loss of

water from the concrete.

i) Ensure that there is no damage or displacement to sheet membranes.

j) Record the time and location of placing structural concrete. Concrete shall normally be compacted in its

final position within thirty minutes of leaving the mixer. Concrete shall be compacted during placing with

approved vibrating equipment without causing segregation until it forms a solid mass free from voids

thoroughly worked around reinforcement and embedded fixtures and into all corners of the formwork.

Immersion vibrators shall be inserted vertically at points not more than 450 mm apart and withdrawn

slowly till air bubbles cease to come to surface, leaving no voids. When placing concrete in layers

Signature of Bidder Page 53 of

Ahmedabad Municipal Corporation

advancing horizontally, care shall be taken to ensure adequate vibration, blending and melding of

concrete between successive layers. Vibrators shall not be allowed to come in contract with

reinforcement, formwork and finished surfaces after start of initial set. Over vibration shall be

avoided.Concrete may be conveyed and placed by mechanically operated equipment after getting the

complete procedure approved by Engineer. The slump shall be held to the minimum necessary for

conveying concrete by this method. When concrete is to be pumped concrete mix shall be specifically

designed to suit pumping. Care shall be taken to avoid stoppages in work once pumping has

started.Except when placing with slip forms, each placement of concrete in multiple lift work, shall be

allowed to set for at least 24 hours after the final set of concrete before the start of subsequent

placement. Placing shall stop when concrete reaches the top of the opening in walls or bottom surface of

slab, in slab and beam construction, and it shall be resumed before concrete takes initial set but not until

it has had time to settle as determined by Engineer. Concrete shall be protected against damage until

final acceptance.

Curing and protection shall start immediately after the compaction of concrete to protect it from:

(a) Premature drying out, particularly by solar radiation and wind;

(b) Leaching out by rain and flowing water;

(c) Rapid cooling during the first few days after placing;

(d) High internal thermal gradients;

(e) Low temperature of frost;

(f) Vibration and impact which may disrupt the concrete and interfere with its bond to the

reinforcement.All concrete, unless directed otherwise by Engineer, shall be cured by use of continuous

sprays or pounded water or continuously saturated coverings of sacking, canvas, hessian or other

absorbent material for the period of complete hydration with a minimum of 7 days. The quality of curing

water shall be the same as that used for mixing.Where a curing membrane is directed to be used by the

Engineer, the same shall be of a non-wax base and shall not impair the concrete finish in any manner. The

curing compound to be used shall be got approved from the Engineer before use and shall be applied

with spraying equipment capable of a smooth, even textured coat. Curing may also be done by covering

the surface with an impermeable material such as polyethylene, which shall be well sealed and fastened.

Extra precautions shall be exercised in curing concrete during cold and hot weather.

CONSTRUCTION JOINTS AND KEYS

Construction joints will be as shown on the drawing or as approved by Engineer. Concrete shall be placed

without interruption until completion of work between construction joints. If stopping of concreting

becomes unavoidable anywhere, a properly formed construction joint shall be made with the approved

of Engineer. Dowels for concrete work, not likely to be taken up in the near future, shall be coated with

cement slurry and encased in lean concrete as indicated on the drawings or as directed by Engineer.

Before resuming concreting on a surface which has hardened all laitance and loose stone shall be

thoroughly removed by wire brushing/hacking and surface washed with high pressure water jet and

treated with thin layer of cement slurry for vertical joints and a 15 mm thick layer of cement sand mortar

for horizontal layers, the ratio of cement and sand being the same as in the concrete mix. When

Signature of Bidder Page 54 of

Ahmedabad Municipal Corporation

concreting is to be resumed on a surface which has not fully hardened, all laitance shall be removed by

wire brushing, the surface wetted, free water removed and a coat of cement slurry applied. On this a

layer of concrete not exceeding 150 mm thickness shall be placed and well rammed against the old work.

There after work shall proceed in the normal way.

FOUNDATION BEDDING

All earth surfaces upon which or against which concrete is to be placed, shall be well compacted and free

from standing water, mud or debris. Soft or spongy area shall be cleaned out and back filled with either

cement mixture, lean concrete or clean sand compacted as directed by Engineer. The surfaces of

soils shall be moistened.

The frame work for concrete works shall be such as to give the finish as specified; defects due to bad

workmanship (e.g. damaged or misaligned forms, defective or poorly compacted concrete) will not be

accepted. The Contractor shall construct the formwork using the correct materials and to meet the

requirements of the design and to produce finished concrete to required dimensions, plumbs, planes and

REPAIR AND REPLACEMENT OF UNSATISFACTORY CONCRETE

Immediately after the shuttering is removed, all the defective areas such as honey combed surfaces,

rough patches, holes left by form bolts etc. shall be brought to the notice of Engineer who may permit

patching of the defective areas or reject the concrete work. All though holes for shuttering shall be filled

for full depth and neatly plugged flush with surface. Rejected concrete shall be removed and replaced by

Contractor at no additional cost to Client.For patching of defective areas all loose materials shall be

removed and the surface shall be prepared as directed by the Engineer.Bonding between hardened and

fresh concrete shall be done either by placing cement mortar or by applying epoxy. The decision of the

Engineer as to the method of repairs to be adopted shall be final and binding on the Contractor and no

extra claim shall be entertained on this account. The surface shall be saturated with water for 24 hours

before patching is done with 1:5 cement sand mortar. The use of epoxy for bonding fresh concrete shall

be carried out as directed by Engineer.

HOT WEATHER REQUIREMENTS

Concreting during hot weathers shall be carried out as per IS: 7861 (Part-I) Adequate provisions shall be

made to lower concrete temperatures which shall not exceed 40 Deg. C at the time of placement of fresh

concrete.Where directed by Engineer, Contractor shall spray non-wax based curing compound of

unformed concrete surfaces at no extra costs.

COLD WEATHER REQUIREMENTS

Concreting during cold weather shall be carried out as per IS : 7861 (Part-II). The ambient temperature

during placement and upto final set shall fall below 5 Deg. C. Approved antifreeze/accelerating additives

shall be used where directed.For major and large scale concreting works the temperature of concrete at

testing such as temporary bulk heads, pressure gauges, pumps, pipelines etc.Any temporary

arrangements that may have to be made to ensure stability of the structures shall also be considered to

have been taken into account while quoting the rates.Any leakage that may occur during the hydro-test

or subsequently during the defects liability period or the period for which the structure is guaranteed

shall be effectively stopped either by cement/epoxy pressure grouting, gunting or such other methods as

may be approved by the Engineer. All such rectification of the Client / Engineer at no extra cost to the

TESTING CONCRETE STRUCTURE FOR LEAKAGE

Hydro-static test for water tightness shall be done at full storage by Engineer, as described below:

In case of structures whose external faces are exposed, such as elevated tanks, the requirements of the

test shall be deemed to be satisfied if the external faces show no sign of leakage or sweating and remain

completely dry during the period of observation of seven days after allowing a seven day period for

absorption after filling with water.In case of structures whose external faces are submerged and are not

accessible for inspection, such as underground tanks, the structures shall be filled with water and after

the expiry of seven days after filling,the level of the surface of the water shall be recorded. The level of

water shall be recorded again at subsequent intervals of 24 hrs, over a period of seven days. Backfilling

shall be withheld till the tanks are tested. The total drop in surface level over a period for seven day shall

be taken as an indication of the water tightness of the structure. The Engineer shall decide on the actual

permissible nature of this drop in the surface level, taking into account weather the structures are open

or closed and the corresponding effect it has on evaporation losses. Unless specified otherwise, a

structure whose top is covered shall be deemed to be water tight if the total drop in the surface level

over a period of seven days does not exceed 40 mm.

Each compartment/segment of the structure shall be tested individually and then all together.For

structures such as pipes, tunnels etc. the hydro-static test shall be carried out by filling with water, after

curing as specified, and subjecting to the specified test pressure for specified period. If during this period

the loss of water does not exceed the equivalent of the specified rate, the structure shall be considered

to have successfully passed the test.

If Engineer feels that the materials i.e. .cement, sand coarse aggregates, reinforcement and water are not

in accordance with the specifications or if specified concrete strengths are not obtained, he may order

tests to be carried out on these materials in laboratory, to be approved by the Engineer, as per relevant

IS Codes. Client shall pay only for the testing of material supplied by the Client, otherwise Contractor shall

have to pay for the tests. Transporting of all material to the laboratory shall however be done by the

Contractor at no extra cost to client. In the even of any work being suspected of faulty material or

workmanship requiring its removal or if the works cubes do not give the stipulated strengths, Engineer

reserves the right to order the Contractor to take out cores and conduct tests on them or do ultrasonic

testing or load testing of structure, etc. All these tests shall be carried out by Contractor at no extra cost

to the Client. Alternatively Engineer also reserves the right to ask the Contractor to dismantle and re-do

such unacceptable work at the cost of Contractor. If the quoted unit rates/prices of concrete shall be

deemed to provide for all tests mentioned above.

All materials, workmanship and finished construction shall be subject to continuous inspection and

approval of Engineer. Materials rejected by Engineer shall be expressly removed from site and shall be

replaced by Contractor immediately at no extra cost to Client.

Upon the completion of concrete work, all forms, equipment, construction tools, protective coverings

any debris, scraps of wood etc. resulting from the work shall be removed and the premises left clean.
