 INDRAPRASTHA GAS LTD. TECHNICAL SPECIFICATIONS IGL/ND/C&P/EC15509

M – 25 (Nominal mix) 2.1 2.8

The water cement ratio, coarse aggregates and grading for each mix shall be predetermined
from the results of cube tests of trial mixes. The mix proportions determined thus shall be
followed at site and shall in no way relieve the contractor of his responsibility as regards the
prescribed strength mix. The mix proportions, however, shall be revised if the results of the cube
tests during the construction show consistently lower than the prescribed one. No claim to alter
the rates of concrete work will be entertained due to such changes in mix designs, as the
contractor will be responsible to produce the concrete of required grade. The aggregates shall
be measured by volume.

All concrete shall be controlled concrete confirming to IS:456:2000. For mud-mat and filling
purpose, ordinary concrete of 1:4:8 for proportion or as specified may be used as indicated in
drawings.

04.03 Mixing

Mixing should be carried out in mechanical mixers. Hand mixing can however be permitted by
Engineer-in-charge in special cases subject to additional 10% extra cement without extra cost.
Water cement ratio shall be rigidly controlled during mixing. Mixers shall be fitted with automatic
devices to discharge measured quantity of water directly to the mixing pan. The water shall not
be admitted to the drum until all the cement and aggregate constituting the batch are thoroughly
mixed. Mixing shall continue until the concrete is uniform in colour and not less than 2 minutes
after all the materials and water are in the drum.

04.04 Placing

The place where concrete is to be poured should be clean and free from all lose dirt, wooden
pieces, dust, standing water etc. The form-work must be right and rigid, with all holes and
crevices stopped effectively, to prevent cement slurry from running out.

Walking on reinforcement layers is not permissible. Walkways of wooden planks or similar can
be placed with removable supports and should be independent of the reinforcement. The
reinforcement position should not be disturbed nor should it sag during carriage and placement
of concrete.

Placing and vibration should not take totally more than 20 minutes from time of mixing. Method
of placing should be got approved by Engineer-in-charge. Segregation during carriage and
placement should be avoided if during carriage concrete segregates, it should be re-mixed
before placement.

Concrete should not be dropped from a height of over 1.5M.

To ensure bond and water tightness between old concrete surface and fresh concrete to be
placed, the surface should be cleaned and roughened by “initial green out” by wire brushing or

Civil & Electrical work in new CGS Page 89 of 166

 INDRAPRASTHA GAS LTD. TECHNICAL SPECIFICATIONS IGL/ND/C&P/EC15509

chipping. The initial green cutting may be done by wire brush after 6 hours of placing concrete
in order to facilitate the work. Chipping can be done only after 48 hours.

A layer of cement slurry with 1.1 mix (1 cement : 1 sand) should be poured to obtain a uniform
coating on old concrete. Immediately thereafter, the fresh concrete should be poured.

Concrete shall be placed in a single operation to the full thickness of slabs, beams and similar
members and shall be placed in horizontal layers not exceeding 1.5m deep in walls, columns
and similar members. Concrete shall be placed continuously until completion of the part of the
work between construction joints or as directed by Engineer-in-Charge.

04.05 Placing in the inclement Weather

All precautions shall be taken for concreting in extreme weather in accordance with relevant
clause of IS:456:2000. Due protection shall be provided to prevent cement being blown away
while proportioning and mixing during windy weather. No concreting shall be carried out in
continuous heavy rains and necessary arrangements to cover the freshly poured concrete shall
be provided, to protect it from the direct rays of the sun and from drying winds.

All concreting placements should be coordinated with placement of conduits, inserts, and
embedded parts etc. executed either by same agency or separately.

Concrete in standing water shall be executed strictly as per IS : 456:2000.This shall be paid as
a separate item where applicable.

04.06 Vibration

Concrete shall be compacted by means of vibrators of approved type under proper supervision
as directed by the Engineer-in-Charge. The whole mass of concrete shall be well vibrated until
a dense mass with a jelly like appearance and consistency and water just appearing on the
surface is obtained. Over vibration and vibration of very wet mixes shall be avoided. Care
should be taken to avoid segregation and formation of air bubbles.

04.07 Construction Joint

Construction joints shall be made in the position as indicated in drawings and as approved by Engineer-in-charge.
Such joints shall be truly vertical or horizontal as the case may be except that in an inclined or curved member
the joint shall be strictly at right angles to the axis of the member.

Civil & Electrical work in new CGS Page 90 of 166

 INDRAPRASTHA GAS LTD. TECHNICAL SPECIFICATIONS IGL/ND/C&P/EC15509

04.08 Curing & Protection

The concrete shall be kept constantly wet for at least seven days from the date of placing of
concrete. In very hot weather precaution shall be taken to see that temperature of wet concrete
does not exceed 38°C while placing.

Concrete shall not be disturbed after initial setting has started. For freshly laid concrete formwork
shall not be jarred. Concrete placed below ground surface shall be protected from falling earth
during and after placing.

04.09 Finishes

On striking the formwork, all blow holes and honeycombing observed shall be brought to the
notice of Engineer-in-Charge. The Engineer-in-charge may at his discretion allow such honey
combing or blow holes to be rectified by necessary chipping and packing or grouting with
concrete or cement mortar.

If mortar is used, it shall be 1:3 mix or as specified by Engineer-in-Charge. However, if honey-

combing or blow holes are of such extent as being undesirable the Engineer-in-Charge may
reject the work totally and his decision shall be binding on the contractor. No extra payment
shall be made for rectifying these defects. All burrs and uneven faces shall be rubbed smooth
by carborundum stone.

The surface of non-shuttered faces shall be smoothened with a wooden float to give a finish
equal to that of the rubbed down shuttered faces. Concealed concrete faces shall be left as from
the shuttering except that honey combed surface shall be made good as detailed above. The
top faces of slabs not intended to be surfaced shall be leveled and floated smooth at the levels
or slopes shown on drawings. The floating shall not be executed to the extent of bringing excess
fine materials to the surface. The top faces of slab intended to be covered with screed,
granolithic or similar surface shall be left with a rough finish. Sides and soffits to be later covered
with plaster shall be suitably roughened.

At least one Vee-Bee Test/Slump Test shall be made for every compressive strength test carried
out. More frequent tests shall be made if there is a distinct change in working conditions or if
required by the Engineer-in-Charge .

04.11 Strength Test of Concrete

Samples from fresh concrete shall be taken as per IS:1199 and cubes shall be made, cured and
tested at 28 days in accordance with IS:516.

In order to get a relatively quicker idea of the quality of concrete, optional tests on beams for
modulus of rupture at 72+2 hours or at 7 days, or compressive strength tests at 7 days may be
carried out in addition to 28 days compressive strength tests. For this purpose, the values as
given may be taken for general guidance in the case of concrete made with Ordinary Portland
Cement. In all cases, the 28 days compressive strength as specified shall alone be the criterion
for acceptance or rejection of the concrete from strength consideration. If, however, from tests

Civil & Electrical work in new CGS Page 91 of 166

 INDRAPRASTHA GAS LTD. TECHNICAL SPECIFICATIONS IGL/ND/C&P/EC15509

carried out in a particular work over a reasonably long period, it has been established to the
satisfaction of Engineer-in-Charge that a suitable ratio between 28 days compressive strength
and modulus of rupture at 72+2 hours or compressive strength at 7 days compressive strength
as specified, provided the expected strength values at the specified early age are consistently
met. However, set of test cubes for 28 days strength test shall always be taken and maintained
to cater to any contingencies in the event of failure of 7 days strength.

04.12 Procedure

A random sampling procedure shall be adopted to ensure that each concrete batch shall have a
reasonable chance of being tested, that is the sampling should be spread over the entire period
of concreting and cover all mixing units.

4.13 Frequency of Sampling

The minimum frequency of sampling of concrete for each grade shall be in accordance with the
following:

Quantity of concrete in the work in m

3 Number of samples

1-5 1

6-15 2

16-30 3

31-50 4

51 & above 4 plus one additional sample for each additional

3
50 m or part thereof

Note: At least one sample shall be taken from each shift. Wherever concrete is produced at
continuous production unit, such as ready –mixed plant, frequency of sampling may agreed
upon mutually by suppliers and Engineer-in-charge.

04.14 Test Specimen

Three test specimens shall be made from each sample for testing at 28 days. Additional cubes
may be required for various purposes such as to determine the strength of concrete at 7 days or
at the time of striking the form work, or to determine the duration of curing, or to check the testing
error. Additional cubes may also be required for testing cubes cured by accelerated methods
as described in IS:9013. The specimen shall be tested as described in IS:516.

Civil & Electrical work in new CGS Page 92 of 166

 INDRAPRASTHA GAS LTD. TECHNICAL SPECIFICATIONS IGL/ND/C&P/EC15509

04.15 Test Strength of Sample

The test strength of the sample shall be the average of the strength of three specimens. The
individual variation should not be more than + 15 percent of the average.

1. The concrete test failing to attain the specified strength.

2. Suspected over loading construction of the structure.

3. Shuttering being prematurely removed and not as per time specified in IS:456:2000.

4. Concrete improperly cured.

The contractor shall carry out tests at his own cost. If the results of the loading test be
unsatisfactory, the Engineer-in-Charge may instruct the contractor to demolish and
reconstruct the structure or part thereof at the contractor’s cost.

05.00 Formwork & Centering

Formwork in general shall conform to IS 456:2000.

For complicated work, the contractor shall submit his proposal of formwork before starting the
work for the approval of the Engineer-in-Charge. The number of props, their sizes and
dispositions shall be such as to be able to safely carry the full dead load and constructional
loads. However, approval of the Engineer-in-Charge to this effect shall not relieve the contractor
of his responsibility for proper work and safety.

All forms of beams, slabs and similar members shall be so designed and erected that the sides
can be removed without disturbing the soffit shutter and supports there to.

Beam soffit shall be provided with an upward, camber of 6mm for each 3M of horizontal span or
as directed by the Engineer-in-Charge. Vertical props shall be supported on wedges or sole
plates or other measures where by the props can be gently lowered while commencing to
remove the shuttering. Columns shuttering shall not be over 1.5M in height apiece.

Before removal of the shuttering the concrete shall be examined and it removal order taken from
the Engineer-in-Charge. In no circumstances shall forms be struck until the concrete reaches a
strength of at least twice the stress to which the concrete may be subjected at the time of striking.

Shuttering shall not be removed until the number of clear days specified in IS:456:2000 have
elapsed since the last day of placing concrete in the member concerned. All formwork shall be
removed without such shock or vibration as would damage the reinforced concrete. Before the
soffits and struts are removed the concrete surface shall be exposed, where necessary order to
ascertain in that the concrete has sufficiently hardened. The specified period may be extended
if desired by the Engineer-in-Charge on account of delayed hardening caused by low
atmospheric temperature.

06.00 Reinforcement in cement concrete

The steel for reinforcing bars shall be as indicated in drawings and conforming to specifications.

All reinforcement at the time of concreting, shall be free from loose rust or scales, oil, grease or
other harmful matter, and other castings that will destroy or reduce the bond.

The number, size, form and position of all the reinforcement shall, unless otherwise directed or
authorised by the Engineer-in-Charge be strictly in accordance with the drawings. Wherever
inserts interfere with the placing of reinforcement, proper adjustment shall be made as directed
by Engineer-in-Charge, before concrete is placed.

Civil & Electrical work in new CGS Page 93 of 166

 INDRAPRASTHA GAS LTD. TECHNICAL SPECIFICATIONS IGL/ND/C&P/EC15509

All reinforcement work shall conform to IS:456:2000.

The steel reinforcement shall be connected to form a rigid cage. To prevent displacement before
or during concreting the bars shall be secured to one another with 16 SWG black annealed
binding wire. Bars intended to be in contact at passing points shall be securely wired together
similarly at all such points. Wooden planks provided for labour to move shall be supported
independent from the reinforcement cage, and the cage shall never be remitted to sag or get
displaced during concreting.

The vertical distances required between successive layers of bars in beams or similar members
shall be maintained by the provisions of steel spacer bars inserted at such intervals that the main
bars do not perceptibly sag between adjacent spacer bars.

Concrete spacer blocks shall be used to ensure cover of concrete over the bars. The concrete
over the reinforcement bars shall be as shown in drawings and shall be the clean cover.

The contractor must obtain the approval of the Engineer-in-Charge to the reinforcement placed
before any concrete in deposited.

Binding wires and wastages are not to be included in measurements.

07.00 Brick Masonry works

07.01 Cement Mortar

Cement mortar shall meet the requirements of IS:2250 and shall be prepared by mixing cement
and sand by volume in a mechanical mixer. Proportion of cement and sand shall be 1:6 (1 part
of cement and 6 parts of sand), or as directed by the Engineer-in-Charge/shown on the drawing,
for brick masonry of one brick thickness or more, while 1:4 cement mortar (1 part of cement and
4 parts of sand) shall be used for brick masonry of half brick thickness. The sand being used for
mortar shall be sieved. The mortar shall be used as soon as possible after mixing and before it
has begun to set and in any case within initial setting time of cement after water is added to the
dry mixture. Mortar unused for more than initial setting time of cement, shall be rejected and
removed from the site of work.

07.02 Proportioning

The unit of measurement for cement shall be a bag of cement weighing 50 kgs and this shall be
taken as 0.035 cubic meter. Sand shall be measured in boxes of suitable size on the basis of
its dry volume. In case of damp sand, its quantity shall be increased suitably to allow for bulkage.

07.03 Mixing
The mixing of mortar shall be done in a mechanical mixer operated manually or by power. The
Engineer-in-Charge may, however, permit hand-mixing as a special case, taking into account
the magnitude, nature and location of work. The Contractor shall take the prior permission of
Engineer-in-Charge, in writing, for using hand-mixing before the commencement of work.

07.04 Mixing in Mechanical Mixer

Cement and sand in specified proportions, by volume, shall be thoroughly mixed dry in a mixer.
Water shall then be added gradually and wet mixing continued for at least one minute. Care
shall be taken not to add more water than that which shall bring the mortar to the consistency of
stiff paste. Wet mix from the mixer shall be unloaded on water-tight masonry platform, made
adjacent to the mixer. Platform shall be at least 150 mm above the leveled ground to avoid
contact of surrounding earth with the mix. Size of the platform shall be such that it shall extend
at least 300mm around the loaded wet mix area. Wet mix, so Portland cement conforming to

Civil & Electrical work in new CGS Page 94 of 166

 INDRAPRASTHA GAS LTD. TECHNICAL SPECIFICATIONS IGL/ND/C&P/EC15509

IS:269 after addition of water. Mixer shall be cleaned with water each time before suspending
the work.

07.05 Hand Mixing

The measured quantity of sand shall be leveled on a clean water tight masonry platform and
cement bags emptied on top. The cement and sand shall be thoroughly mixed dry by being
turned over and over, backward and forward, several times till the mixture is of uniform colour.
The quantity of dry mix which can be consumed within initial setting time of cement shall then
be mixed with just sufficient quantity of water to bring the mortar to the consistency of stiff paste.

07.06 Construction Procedure

Soaking of Bricks

Bricks shall be soaked in water before use for a period that is sufficient for the water to just
penetrate the whole depth of bricks as well as to remove dirt, dust and sand. Proper soaking of
bricks shall prevent the suction of water from the wet mortar as otherwise mortar will dry out
soon and crumble before attaining any strength. The bricks shall not be too wet at the time of
use as they are likely to slip on mortar bed and there will be difficulty in achieving the plumpness
of wall as well as proper adhesion of bricks to mortar. The period of soaking shall be determined
at site by a field test by immersing the bricks in water for different periods and then breaking the
bricks to find the extent of water penetration. The least period that corresponds to complete
soaking, will be the one, to be allowed for in the construction work.

The soaked bricks shall be removed from the tank, sufficient early, so that at the time of laying,
they are skin dry. The soaked bricks shall be stacked over a clean place, wooden planks or
masonry platforms to avoid earth, dirt being smeared on them.

07.07 Laying

Brick Work (one or more brick thickness)

Brick work (one or more brick thickness) shall be laid in English Bond unless otherwise specified.
Half or cut bricks shall not be used except when needed to complete the bond. In no case the
defective bricks shall be used.

A layer of average thickness of 10mm of cement mortar shall be spread on full width over a
suitable length of lower course or the concrete surface. In order to check and achieve uniformity
in masonry, the thickness of bed joints shall be such that four courses and three joints taken
consecutively shall measure equal to four times the actual thickness of the brick plus 30mm.
Each brick with frog upward, shall be properly bedded and set in position by gently tapping with
handle of trowel or wooden mallet. Its inside faces shall be buttered with mortar before the next
brick is laid and pressed against it. After completion of the course, all vertical joints shall be filled
from top with mortar.

All brick courses shall be taken up truly plumb; if battered, the batter is to be truly maintained.
All courses shall be laid truly horizontal and vertical joints shall be truly vertical. The level and
verticality of work in walls shall be checked up at every one meter interval.

For brick walls of half brick thickness, all courses shall be laid with stretchers. Wall shall be
reinforced with 2 nos. 6mm diameter mild steel reinforcement bars, placed at every fourth
course. The reinforcement bars, shall be straightened and thoroughly cleaned. Half the mortar
thickness for the bedding joint shall be laid first and mild steel reinforcement, one on each face
of the wall, shall be embedded, keeping a side cover of 12mm mortar. Subsequently the other
half of the mortar thickness shall be laid over the reinforcement covering it fully.

The reinforcement bars shall be carried at least 150mm into the adjoining walls or RCC columns.
In case the adjoining wall being of half brick thickness, the length of bars shall be achieved by
bending the bars in plan. During casting of reinforced concrete columns, 6mm dia. M.S.
reinforcing bar shall be placed at every fourth course of brick masonry. At the junction of two
walls, the brick shall, at each alternate course, be carried into each of the respective walls so as
to thoroughly unite the work. The brick masonry work shall not be raised more than 14 courses
per day.

Brick course under the soffit of beam or slab, shall be laid by restricting the mortar thickness of
12mm. However, any gap between the finished brickwork and soffit to slab/beam, shall be
suitably sealed with the mortar.

11.00 Pile Foundations

11.01 General

This work shall consist of construction of all types of piles for structures in accordance with the
details shown in the drawings and conforming to the requirements of these specifications.

During installation of piles, the sequence of construction shall be followed as directed by the
Engineer.

Civil & Electrical work in new CGS Page 98 of 166

 INDRAPRASTHA GAS LTD. TECHNICAL SPECIFICATIONS IGL/ND/C&P/EC15509

The work shall be done as per IS: 2911 or as shown in drawings. The current project
contemplates the use of only bored cast-in-situ reinforced concrete piles. Integrity testing of
piles shall be required to be done in this project using pile driving analyser or approved equivalent
methodology.

11.02 Materials

Concrete shall conform to IS:456:2000 and other relevant clauses of these specifications.
Reinforcement and binding wire shall conform to IS:456:2000 of these specifications.

Additionally the concrete intended to be used for piles shall be provided with 10% extra cement
over and above that required by all mix design subject to a minimum of 400 kg cement/cum of
concrete.

Grade of concrete to be used in cast-in-situ piles shall be M20 and the cement content shall not
be less than 400 kg per cubic meter of concrete. Maximum water cement ratio shall be 0.45 for
cast-in-situ piles.

The minimum slump of concrete for bored cast-in-site piles shall be 150mm to 200mm. The
slump should not exceed 200mm in any case.

Concrete mix should have homogeneous mixture with required workability for the system of
piling adopted. Suitable and proven admixtures may be used in concrete mix where necessary.

11.03 Test Piles

Test piles which are shown in the drawings, or specified by the Engineer-in-charge in the
contract, or installed by the contractor on his own, to determine the lengths of piles to be
furnished, shall conform to the requirements for piling as indicated in these
specifications/drawings if they are to be incorporated in the completed structure.

Test piles that are to become a part of the completed structure shall be installed with the same
type of equipment that is proposed to be used for piling in the actual structure.

Test piles which are not to be incorporated in the completed structure shall be removed to at
least 600mm below the proposed soffit level of pile cap and the remaining hole shall be back-
filled with earth or other suitable material. These piles shall also be installed with the same type
of equipment that is proposed to be used for piling in the actual structure.

The piles shall be load tested in accordance with provisions laid down in this section.

BORED CAST –IN-SITU REINFORCED CONCRETE PILES

Bored cast-in-situ piles shall be installed by making a bore into the ground by removal of material.
Use of casing, temporary or permanent, shall be made wherever necessary to the satisfaction

Civil & Electrical work in new CGS Page 99 of 166

 INDRAPRASTHA GAS LTD. TECHNICAL SPECIFICATIONS IGL/ND/C&P/EC15509

of the Engineer. Decision regarding the necessity and length of casing shall be certified by the
Engineer.

Any liner or bore-hole which is improperly located or shows partial collapse that would affect the
load carrying capacity of the pile, shall be rejected or repaired as directed by the Engineer at the
cost of the contractor.

Wherever practicable, concrete should be placed in a clean dry hole. Where concrete is placed
in dry and casing is provided, the top 3m of the pile shall be compacted using internal vibrators.
The concrete should invariably be poured through the tremie with a funnel so that the flow is
directed and concrete can be deposited in the hole without segregation. Where the casing is
withdrawn from cohesive soils for the insertion of cast-in-situ pile, the concreting should be done
with necessary precautions to minimize the softening of the soil by excess water. Where mudflow
conditions exist, the casing of cast-in-situ piles shall not be allowed to be withdrawn. No extra
payment shall be made for casing. Care shall be taken during concreting to prevent as far as
possible the segregation of the ingredients. The displacement or distortion of reinforcement
during concreting and also while extracting the tube shall be avoided.

If the concrete is placed inside pre-cast concrete tubes or consists of pre-cast sections, these
shall be free from cracks or other damage before being installed.

The concrete shall be properly graded, shall be self-compacting and shall not get mixed with
soil, excess water, or other indigenous matter. Special care shall be taken in silty clays and other
soils where the tendency is to squeeze into the newly deposited concrete, and cause necking.
Sufficient head of green concrete shall be maintained to prevent inflow of soil or water into the
concrete.

The placing of concrete shall be a continuous process from the toe level to the top of the pile.
To prevent segregation, a tube or tremie pipe as appropriate shall be used to place concrete in
all piles.

To ensure compaction by hydraulic static heads, rate of placing concrete in the pile shaft shall
not be less than 6m (length of pile) per hour.

Bored cast-in-situ piles in soils which are stable, may often be installed with only a small casing
length at the top. A minimum of 3.0m length of top of bore shall invariably be provided with
casing to ensure against loose soil falling into the bore. Cases in which the side soil can fall into
the hole, it is necessary to stabilize the side of the bore hole with drilling mud, or a suitable steel
casing. The casing may be left in position permanently specially in cases where the aggressive
action of the ground water is to be avoided, or in the cases of piles built in water or in cases
where significant length of piles could be exposed due to scour.

For bored cast-in-situ piles casing/liner shall be driven open ended with a pile driving hammer
capable of achieving penetration of the liner to the length shown on the drawing or as approved
by the Engineer. Materials inside the casing shall be removed progressively by air life, grab or
percussion equipment or other approved means. Where bored cast-in-situ piles are used in soils

Civil & Electrical work in new CGS Page 100 of 166

 INDRAPRASTHA GAS LTD. TECHNICAL SPECIFICATIONS IGL/ND/C&P/EC15509

liable to flow, the bottom of the casing shall be kept enough in advance of the boring tool to
prevent the entry of soil into the casing, thus preventing the formation of cavities and settlements
in the adjoining ground. The water level in the casing should generally be maintained at the
natural ground water level for the same reasons. The joints of the casing shall be made as tight
as possible to minimise inflow of water or leakage of slurry during concreting.

Boring shall be carried out using approved rotary or percussion type equipment.

Prior to the lowering of the reinforcement cage into the pile shaft, the shaft shall be cleaned of
all loose materials. Cover to reinforcing steel shall be maintained by suitable spacers.

The diameter of the finished pile shall not be less than that specified and a continuous record
shall be submitted to the Engineer as to the volume of concrete placed in relation to the pile
length cast. The same shall be plotted on a graph paper to judge the profile of pile over its
length.

Before concreting under water, the bottom of the hole shall be cleaned of drilling mud and all
soft or loose material very carefully. In case a hole is bored with use of drilling mud. Concreting
should not be taken up when the specific gravity of bottom slurry is more than 1.2. The drilling
mud should be maintained at 1.5m above the ground water level.

General requirements and precautions for concreting underwater are as follows:

A) The concreting of pile must be completed in one continuous operation. Also, for bored holes,
the finishing of the bore, cleaning of the bore, lowering of the reinforcement cage and concreting
of pile for full height must be accomplished in one continuous operation with any stoppage.

B) The concrete should be coherent, rich in cement with high slump and restricted water cement
ratio.

C) The tremie pipe will have to be large enough with due regard to the size of aggregate. For 20mm
aggregate the tremie pipe should be of diameter not less than 150mm and for larger aggregate,
larger diameter tremie pipes may be necessary.

D) The first charge of concrete should be placed with a sliding plug pushed down the tube ahead
of it to prevent mixing of water and concrete.

E) The tremie pipe should always penetrate well into the concrete (minimum 1.0m) with an
adequate margin of safety against accidental withdrawal if the pipe is surged to discharge the
concrete.

F) The pile should be concreted wholly by tremie and the method of deposition should not be
changed part way up the pile to prevent the laitance from being entrapped with the pile.

G) All tremie tubes should be scrupulously cleaned after use.

The reinforcement in the pile shall be exposed for full anchorage length to permit it to be
adequately bonded into the pile cap.

Defective piles shall be removed or left in place as judged convenient without affecting the
performance of adjacent piles or pile cap. Additional piles shall be provided to replace the
defective piles.

11.04 Pile Test

The load test on a concrete pile shall not be carried out earlier than 28 days from the time of
casting of the pile.

Civil & Electrical work in new CGS Page 101 of 166

 INDRAPRASTHA GAS LTD. TECHNICAL SPECIFICATIONS IGL/ND/C&P/EC15509

There shall be two categories of static tests on piles, namely, initial tests and routine tests. Initial
tests should be carried out on test piles, which are not to be incorporated in the work. Routine
tests shall be carried out as a check on working piles. The number of initial and routine tests on
piles shall be as determined by the Engineer depending upon the number of foundations, span
length, type of superstructure and uncertainties of founding strata. In any case, the initial load
tests shall not be less than 2 in number, while the routine load tests shall not be less than 2% of
the total number of piles in the structure nor less than 2 in number. These tests shall be carried
out at a cut-off level wherever practicable. Other wise, allowance shall be made in the
interpretation of test results if the test is not made at cut-off level.

Reaction may be applied using kentledge, anchor piles or soil anchors with the prior approval of
the scheme by the Engineer. Reaction to be made available shall be 25% more than the test
load.

The methodology of carrying out load tests and of arriving at safe load on piles shall conform to
IS:2911 (Part iv).

All pile tests shall be duly recorded and analysed with calculations in format approved by the
Engineer.

INITIAL TEST
The test shall generally conform to IS:2911 (part IV) 1985. Pile head shall be prepared for load
test by suitably cutting /bending the projecting pile reinforcement. A bearing plate with a hole at
center shall be placed over the pile head for placing the jacks.
Approximately 15mm gap between the bearing plate and pile head shall be kept which will be
filled with free-flowing non-shrink mortar such as FOSROC’S CONBEXTRA-GP2. Nothing extra
shall be paid on this account. Test load shall be equal to 2.5 times the estimated capacity of pile
of 425t. Interpretation of pile load capacity shall be done as per cl. 6.1.5 of IS:2911 (part IV)
1985.
ROUTINE TEST
The test shall generally conform to IS:2911 (part IV) 1985. Preparation of pile head and
placement of bearing plate including non-shrink mortar shall be as explained in the above clause.
The load shall be equal to 1.5 times the estimated capacity of pile determined as per above
clause. Interpretation of results shall be done as per of IS:2911 (part iv) 1985. The test shall be
carried out not earlier than 28 days after concreting of the pile unless specifically permitted
otherwise by the Engineer.

Selection of the piles for routine load test, which is often the most inferior set of piles, shall be
made by the Engineer, determined by integrity tests.

INTEGRITY TEST
This dynamic test using pile driving analyser or approved equivalent for pile integrity shall be
performed on the sample of piles selected by the Engineer. The top of pile shall be made
accessible, chipped off up to hard concrete, leveled by trimming it back as far as practicable.
The reinforcing bars of the piles to be tested shall be sent sideways.

The test shall be performed after removal of bad/weak concrete at top so that the wave
propagation is steady through hard concrete. The test shall be carried out at least 15 days after
concreting of the piles. The test shall be carried out at minimum of 3 locations on each pile in
such a way that the entire cross-section of the pile is evenly covered. A specialist approved
agency shall be employed for the test and the tests shall generally be as per recommendations
of the agency, unless directed otherwise by the Engineer.

11.05 Pile Cap

Pile caps shall be of reinforced concrete. A minimum offset of 150mm shall be provided beyond
the outer faces of the outer most piles in the group. If the pile cap is in contact with earth at the
bottom, a leveling course of minimum 75mm thickness of PCC1:4:8 shall be provided or as
shown in the drawings.
The attachment of the pile head to the cap shall be adequate for the transmission of loads and
forces. A portion of pile top may be stripped of concrete and the reinforcement anchored into the
cap. Manual chipping may be permitted after three days of pile casting while pneumatic tools
for chipping shall not be used before seven days after pile casting. The top of pile after stripping
shall project at least 75mm into the pile cap. Concreting of the pile cap shall be carried out in dry
conditions.

The top of concrete in a pile shall be brought minimum one diameter above cut-off level to permit
removal of all latiance and weak concrete before pile cap is laid. This will ensure good concrete
at the cut-off level.

IMPORTANT CONSIDERATIONS, INSPECTION / PRECAUTIONS FOR BORED CAST-IN

SITU PILES

While concreting uncased piles, voids in concrete shall be avoided and sufficient head of
concrete is to be maintained to prevent inflow of soil or water into the concrete. It is also
necessary to take precaution during concreting to minimize the softening of the soil by excess
water. Uncased cast-in situ piles shall not be allowed where mudflow conditions exist.
The drilling mud such as bentonite suspension shall be maintained at a level sufficiently above
the surrounding ground water level to ensure the stability of the strata which is being penetrated
throughout the boring process until the pile has been concreted.

Where bentonite suspension is used to maintain the suability of the bore-hole it is essential that
the properties of the material be carefully controlled at stages of mixing, supply to the bore-hole
and immediately before concrete is placed. It is usual to limit:

The density of bentonite suspension to 1.05 g/cc

The marsh cone viscosity between 30 and 40

The ph value between 9.5 and 12

The silt content less than 1 per cent

The liquid limit of bentonite not less than 400%

These aspects shall act as controlling factors for preventing contamination of bentonite slurry for
clay and slit.

The bores shall be washed by bentonite flushing to ensure clean bottom at two stages viz. After
completion of boring and prior to concreting after placing of reinforcement cage. Flushing of
bentonite shall be done continuously with fresh bentonite slurry till the consistency of in flowing
and out-flowing slurry is similar.

Tremie of 150mm to 200mm diameter shall be used for concreting. The tremie should have
uniform and smooth cross-section inside, and shall be withdrawn slowly ensuring adequate
height of concrete outside the tremie pipe at all stages of withdrawal. Other recommendations
for tremie concreting are:

Civil & Electrical work in new CGS Page 103 of 166

 INDRAPRASTHA GAS LTD. TECHNICAL SPECIFICATIONS IGL/ND/C&P/EC15509

the sides of the bore hole have to be stable throughout

the tremie shall be water tight throughout its length and have a hopper attached at its head by
a water tight connection.

the tremie pipe shall be larger enough in relation to the size of aggregates. For 20mm aggregate
the tremie pipe shall be of diameter not less than 150mm and for larger size aggregate tremie
pipe of larger diameter is required.

the tremie pipe shall be lowered of the bottom of the bore-hole, allowing water or drilling mud to
rise inside it before pouring concrete.

the tremie pipe shall always be kept full of concrete and shall penetrate well into the concrete
(minimum 1.0m) in the bone-hole with adequate margin of safety against accidental withdrawal
if the pipe is surged to discharge the concrete.

For very long or large diameter piles, use of retarding plasticiser in concrete is desirable.

Where possible, it may be desirable to grout the base of pile with cement slurry under suitable
pressure after concrete in the pile attains the desired strength. For this purpose, conduit pipes
with easily removable plugs at the bottom end should be placed in the bore along with
reinforcement cage before concreting. No extra payment shall be made for the same.

constructional Chemical Treatment Measures) subject to the minimum requirements given in this
specification.

Treatment shall commence after excavation for foundation is ready, leveling/compacting of filled
soil, and before any damp proof membrane is laid under floors. The earth filling immediately
under the stone soiling (under floors), bottom and side fills of all foundations buildings shall be
chemically treated against termites.

The chemicals to be used for the treatment shall be formulation of approved soil toxicants like
Chloropyrifos emulsifiable concentrates 1 % confirming IS:8944 shall be used. The chemical
solution shall be prepared by mixing chemical with the appropriate quantity of water to obtain a
chemical emulsion of the correct concentration as stipulated. The prepared emulsion shall be
applied as described below.

Column Pits, Wall trenches etc.:

The bottom surface and sides of the excavations (up to a height of 30 cm from the bottom) made
for column foundations, wall foundations, etc., (excepting RCC foundations) shall be treated with
the chemical emulsion at the rate of 5 liters per sq.m. of surface area.

Treatment of Back fill:

After the column foundations, wall foundation, etc. have come up, the back fill in immediate
contact with the foundation structure shall be treated at the rate of 15 liters per sq.m. of the
surface of the substructure for each side. If water is used for ramming the earth fill, the chemical
treatment shall be done after ramming operation is completed by rodding earth at 15 cm centers
close to the wall face and spraying the chemical with the above doze. The earth is to be returned
in layers and the treatment shall also be carried out in similar stages. The chemical emulsion
shall be directed towards the masonry wall surfaces so that the earth in contact with these
surfaces is well treated with the chemical.

RCC Walls and Columns:

The treatment shall start at the depth of 50cm below natural ground level. From this depth the
back fill around the RCC columns, walls, etc., shall be treated at the rate of 15 liters per sq.m. of
the surface.

Top Surface of Plinth Filling:

The top surface of the plinth fill (just below the stone soiling) shall be treated with chemical
emulsion at the rate of 5 liters per sq.m. of the surface before the stone soiling is laid. If the filled
earth has been well consolidated and does not permit the emulsion to seep through, holes up to
50 to 75mm deep at 150mm centers both ways be made with crowbars to facilitate saturation of
the soil with the chemical emulsion.

Junction of Wall and Floor:

A channel of size 3cm x 3 cm shall be made at all the junctions and walls and columns with the
floor (before laying the soil) and rod holes made in the channels up to the ground level at 15 cm
centers. The solution is poured into the channel at the rate of 15 liters per sq.m. of the vertical
surface and allowed to soak through the holes so that the soil in contact with the column/wall is
fully soaked with the chemical. The soil shall be tamped back into the channel and consolidated
to original condition.
