GENERAL SITE GRADING

Site grading shall be carried out as indicated in the drawings and as directed by Engineer. Excavation shall

be carried out as specified in the specification. Filling and compaction shall be carried out as specified

elsewhere unless otherwise indicated below.

If no compaction is called for, the fill may be deposited to the full height in one operation and levelled. If

the fill has to be compacted, it shall be placed in layers not exceeding 200 mm and leveled uniformly and

compacted as indicated in before the next layer is deposited.

Signature of Bidder Page 37 of

Ahmedabad Municipal Corporation

To ensure that the fill has been compacted as specified, field and laboratory tests shall be carried out by

Contractor at his cost.

Field compaction test shall be carried out at different stages of filling and also after the entire height has

been completed. This shall hold good for embankments as well.

Contractor shall protect the earth fill from being washed away by rain or damaged in any other way.

Should any slip occur, Contractor shall remove the affected material and make good the slip at his cost.

The fill shall be carried out to such dimensions and levels as indicated on the drawings after the stipulated

compaction. The fill will be considered as incomplete if the desired compaction has not been obtained.

If specifically permitted by Engineer, compaction can be obtained by allowing loaded trucks conveying fill

or other material to ply over the fill area. Even if such a method is permitted, it will be for contractor of

demonstrate that the desired / specified compaction has been obtained. In order that the fill may be

reasonably uniform throughout, the material should be dumped in place in approximately uniform layers.

Traffic over the fill shall then be so routed to compact the area uniformly throughout.

If so specified, the rock as obtained from excavation may be used for filling and leveling to indicate grades

without further breaking. In such an event, filling layers not exceeding 50 cms approximately. After rock

filling the void in the rocks shall be filled with finer materials such as earth, broken stone etc. and the area

flooded so that the finer materials fill up the voids. Care shall be taken to ensure that the finer fill material

does not get washed out. Over the layer so filled, a 100 mm thick mixed layer of broken materials and

earth shall be laid and consolidation carried out by a 12 tonne roller. No less than twelve passes of the

roller shall be accepted before subsequent similar operations are taken up.

The compaction, only where so called for, in the schedule of quantities / items shall comply with the

specified (Standard Proctor / modified Proctor) density at moisture content differing not more than

percent from the optimum moisture content. Contractor shall demonstrate adequately at his cost, by field

and laboratory tests that the specified density has been obtained.

Lead for deposition / disposal of excavated material, shall be as specified in the respective item of

work. For the purpose of measurement of lead, the area to be excavated or filled or area on

which excavated material is to be deposited / disposed off shall be divided into suitable blocks and

for each of the blocks, the distance between centerlines shall be taken as the lead which shall be

measured by the shortest straight line route taken by Contractor. No extra compensation is

admissible on the grounds that the lead including that for borrowed material had to be

transported over marshy or ‘katcha’ land / route.

Measurement and Payment

Backfilling as per specifications on the sides of foundations of columns, footings, structures, walls, tanks,

rafts, trenches etc. with excavated material shall be done. As a rule, material to be backfilled shall stacked

temporarily within the basic lead of 90 meters unless otherwise directed by the Engineer. If Engineer

directs / permits a lead of over 90 meters for such material, the conveyance of the material for the extra

distance over the basic lead of 90 meters for backfilling will be paid for.

not be important and the nominal maximum size may sometimes be as greater than the minimum

2.11 Admixture may used in concrete only with approval of 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 and steel impaired by the use of such admixtures.

3.0 Workmanship:

3.1 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. White 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.

3.2.1 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 half a 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

3.2.2 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 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 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.

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 two thirds of normal quantity of coarse aggregate.

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

3.3 Consistency :

3.3.1 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 I.S. 1199-1959. The slump

of 10mm to 25mm. shall be adopted when vibrators are used and 80mm when vibrators are not

3.4 Inspection:

3.4.1 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

Signature of Bidder Page 55 of

of men, machinery, materials and for results obtained. Immediately before concreting, all forms shall

be thoroughly cleaned.

3.4.2 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

labour 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 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

3.5 Transporting and laying:

3.5.1 The method of transporting and placing concrete shall be as approved. Concrete shall be so

transported and placed that no contemination, segregation or loss of its constituent material takes

All form wok 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.

3.5.2 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 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 n 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.

3.5.3 Unless otherwise agreed to by the Engineer-in-charge, concrete shall not be dropped into place from

a height exceeding 2 meters. When trunking 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

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 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 this surface shall not exceed 150 mm in

thickness and shall be well rammed against old work particular attention being given to corners and

3.5.4 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.

3.6 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, hassain or other similar absorbant 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. Masonary 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.

3.7 Sampling and Testing of concrete:

3.7.1 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 No. of Quantity of concrete in the No. of samples

in the work samples works

51 and above 4+ 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.

3.7.2 The average strength of the group of cubes cast 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

3.8.1 The Engineer-in-charge shall be informed in advance 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 for 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 200 C) 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.

3.8.2 All form work 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 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, the 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 form work, it shall be cleaned and made good to

the satisfaction of the Engineer-in-charge. After removal of form work and shuttering, the Executive

Engineer shall inspect the work and satisfy by random checks that concrete produced is of good

3.8.3 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 be

filled by cement mortar. All fine 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

being finished and of as dry consistency as is possible to use. Considerable pressure shall be applied

in filling and pointing to ensure thorough filling in all voids. Surfaces which are pointed shall be kept

most for a period of 25 hours.

If rock pockets/honeycombs in the opinion of the Engineer-in-charge are of such an extent or

character 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.

(ii) The screed shall have tamping and vibrating arrangement for initial compaction to the

layer as it is spread without rutting or otherwise marring the surface profile.

(iii) The paver shall be equipped with necessary control mechanism so as to ensure that the

finished surface is free from surface blemishes.

The surface of the aggregate shall be carefully checked with templates and all high or low

spots remedied by removing or adding aggregate as may be required.The layer may be

tested by depth blocks during construction.No segregation of large and fine particles

should be allowed.The aggregates as spread should be of uniform gradation with no

pockets of line materials.

17.3.5. Compaction: After the mix has been laid to the required thickness, grade and

crossfall/camber the same shall be uniformly compacted, to the full depth with suitable

roller. If the thickness of single compacted layer does not exceed 100 mm, a smooth

wheel roller of 80 to 100 kN weight may be used. For a compacted single layer upto

mm, the compaction shall be done with the help of vibratory roller of mi8nimum static

weight of 80 to 100 kN or equivalent capacity roller. The speed of the roller shall not

exceed 5 km/h.In portions having unidirectional cross fall/super-elevation, rolling shall

commence from the lower edge and progress gradually towards the upper

edge.Thereafter, roller should progress parallel to the centre line of the road, uniformly

overlapping each preceding track by at least one third width until the entire surface has

been rolled. Alternate trips of the roller shall be terminated in stops at least 1 m away

from any preceding stop.In portions in camber, rolling should begin at the edge with the

roller running forward and backward until the edges have been firmly compacted. The

roller shall then progress gradually towards the centre parallel to the centre line of the

road uniformly overlapping each of the preceding track by at least one-third width until

the entire surface has been rolled.Any displacement occurring as a result of reversing of

the direction of a roller or from any other cause shall be corrected at once as specified

and/or removed and made good.Along forms, kerbs, walls or other places not accessible

to the roller, the mixture shall be thoroughly compacted with mechanical tampers or a

plate compactor.Skin patching of an area without scarifying the surface to permit

proper bonding of the added material shall not be permitted.Rolling should not be done

when the subgrade is soft or yielding or when it causes a wave-like motion in the sub-

base/base course or subgrade.If irregularities develop during rolling which exceed

mm when tested with a 3 metre straight edge,the surface should be loosened and

premixed material added or removed as required before rolling again so as to achieve a

uniform surface conforming to the desired grade and cross fall.In no case should the use

of unmixed material be permitted to make up the depressions.Rolling shall be continued

till the density achieved is at least 98 per cent of the maximum dry density for the

material as determined by the method outlined in IS: 2720 (Part-8).

After completion, the surface of any finished layer shall be well-closed, free from

movement under compaction equipment or any compaction planes, ridges, cracks and

loose material.All loose, segregated or otherwise defective areas shall be made good to

the full thickness of the layer and re-compacted.

17.3.6. Setting and drying: After final compaction of wet mix macadam course,the

road shall be allowed to dry for 24 hours.

17.4. Opening to Traffic

Preferably no vehicular traffic of any kind should be allowed on the finished wet mix

macadam surface till it has dried and the wearing course laid.

17.5. Surface Finish and Quality Control of Work

17.5.1. Surface evenness: The Surface finish of construction shall conform to the

requirements of Clause

17.5.2. Quality Control: Control on the quality of materials and works shall be

exercised by the Engineer in accordance with Section

17.6. Rectification of Surface Irregularity

Where the surface irregularity of the wet mix macadam course exceeds the permissible

tolerance or where the course is otherwise defective due to subgrade soil getting mixed

with the aggregates, the full thickness of the layer shall be scarified over the affected
