section. The extra loose earth at the edges shall be trimmed after completion of the
embankment leaving the correct section fully compacted.
Each layer of the embankment shall be watered, levelled and compacted as specified before
the succeeding layer is placed. The surface of the embankment shall, at all times during
construction, be maintained in such a manner to prevent ponding. Water to be used shall be
free from all harmful contaminants and approved by the Employer’s Representative.
If the material for the embankment contains less than the optimum moisture content, water
shall be added to the 100 mm embankment layers to bring moisture uniformly up to the
optimum. If the excavated material contain more than required moisture, it shall be allowed to
dry until the moisture is reduced to required extent. If due to the wetness, the moisture
content of the soil cannot be reduced to the appropriate amount by exposure, embankment
work shall be suspended until suitable conditions prevail.
When loose layer is placed, levelled and appropriately moistened or dried, it shall be
compacted by 8 to 10 tonne power roller or sheep’s foot rollers or heavy hauling or dozing

ofthe Contractor.
Where slopes steeper than the natural angle of repose or other conditions inconsistent with the
safety of personnel required to work within an excavated area are encountered such
excavations shall be sheeted or shored as may be needed to provide adequate safety.
The Contractor’s attention is specially drawn to the necessity for a thorough study of the site
and soil conditions, groundwater levels and other relevant factors, particularly in the case of
anywet wells, incoming sewer connections and force mains at great depths, before deciding on
the necessity or otherwise of sheeting, shoring and bracing and if provided, the adequacy of
9.2.2 Obstructions
Prior to driving sheeting etc, the Contractor shall locate existing facilities in service, if any, and
avoid sections that may interfere with such. If such avoidance is not possible the Contractor
shall relocate the facility or arrange for its relocation as required to clear the interference. Any
action proposed in such circumstances shall be subject to the prior approval of the Employer’s
Representative.

completion of the work.
Piling shall be driven in stages. No sheet pile, or pair of piles if driven in pairs, shall be driven
more than one-third of its length before the adjacent sheet pile is set. Piling that is damaged or
driven without interlocking shall be withdrawn and re-placed. The Employer’s Representative is
empowered to order withdrawal if he has reasonable grounds to suspect damage. Any
encroachment of piles upon concrete piles shall be sufficient grounds for withdrawal and
If obstructions are encountered during driving, the piles in question shall be driven at least to
the specified refusal driving resistance after adjacent piles have been set and driven. However,
the number of sheet piles permitted to be driven short of the required depths shall be limited in
the field by the Employer’s Representative and if so approved, the Contractor shall remove
obstructions encountered by whatever means necessary.
Splices shall be avoided if practicable, but where unavoidable shall be designed to develop the

preparing the emulsion for the treatment.
The pesticide shall be dispersed uniformly in the soil and to the required strength to form an
effective chemical barrier.
11.3 Delivery, Storage and Handling
Pesticides shall be delivered to the site in sealed and labelled containers in good condition as
supplied by the manufacturer or formulator. The pesticides shall be stored, handled and used in
accordance with manufacturer’s instructions. Labels shall bear evidence of registration as per
the IS or appropriate regulations.
11.4 Site Preparation
In order to ensure uniform distribution of the chemical emulsion and to assist penetration, the
following site preparation shall be carried out:
1 Remove all felled trees, stumps, logs or roots from the site.
2 Remove any concrete formwork, levelling pegs, timber off-cuts and other builder’s debris from the
area to be treated.
3 If the soil to be treated is sandy or porous, preliminary moistening will be required to fill capillary
spaces in the soil to prevent the loss of emulsion through piping or excessive percolation.
4 In the event of water logging of foundation, the water shall be pumped out before application of
the chemical emulsion and it should be applied only when the soilis absorbent.
5 On clays and other heavy soils where penetration is likely to be slow and on sloping sites, where the
treating solution is likely to run-off, the surface of the soil should be scarified to a minimum depth
6 All sub-floor levelling and grading shall be completed, all cuttings, trenches and excavations shall be
completed with backfilling in place. If this is not done, supplementary treatments shall be carried
out to complete the barrier.
At the time of application, the soil shall have sufficiently low moisture content to allow uniform
distribution of the treatment solution throughout the soil. Application of the chemicals shall
not be made during or immediately following heavy rains or when conditions may cause runoff
and create an environmental hazard.
11.5 Application
The Contractor shall apply termiticide to the soil material which will be covered by or lie
immediately adjacent to the buildings and structures to provide a protective barrier against
subterranean termites.
The termiticide shall be applied as a coarse spray and in such manner as to provide uniform
distribution onto the soil surface. This treatment shall be applied prior to placement of a vapour
barrier or waterproof membrane and prior to concrete pouring. Where treated soil or fill
material is not to be covered with a vapour barrier or waterproof membrane, the Contractor
shallexercise adequate precautions to prevent its disturbance.
The chemical emulsion will be applied uniformly by sprayers at the prescribed rates as detailed
below in all the stages of the treatment.
11.5.1 Treatment in Foundation Trenches
In case of normal wall load bearing structures, column pits, wall trenches and basements, the
treatment shall be at 5 l/m2 of surface area of the bottom and sides to a height of at least
mm. After the foundation work, the sides shall be treated at 7.5 l/m 2 of vertical surface of
substructure on each side. After the earth filling is completed, treatment shall be by rodding the
earth at 150 mm centres close to the wall surface and spraying the chemical at a rate of
In the case of framed structures, the treatment shall start at a depth of 500 mm below ground
level. From this depth the backfill around the columns, beams and RCC basement walls shall be
treated at a rate of 7.5 l/m2 for the vertical surface and at 5 l/m2 for horizontal surfaces at the
bottom of trenches/pits.
11.5.2 Treatment on Top Surfaces of Plinth Filling
The top surface of filled earth within plinth walls shall be treated with chemical emulsion at the
rate of 5 l/m2 of the surface area before sub-base to floor is laid. If filled earth has been well
rammed and the surface does not allow the emulsion to seep through, holes up to 50 to 75mm
deep at 150 mm centres both ways shall be made with crow bars on the surface to facilitate
saturation of the soil with the emulsion.
11.5.3 Treatment at Junction of Walls and Floors
Special care shall be taken to establish continuity of the vertical chemical barrier on the inner
wall surfaces from the finished ground level (or from level where the treatment has stopped)
up to the level of the filled earth surface. To achieved this, a small channel 30 x 30 mm shall be
made at all the junctions of wall/column with the floor (before laying sub-grade) and rod holes
made in the channel up to the finished ground level at 150 mm spacings and the iron rod
moved backward and forward to break the earth and the chemical emulsion shall be poured
along the channel at 7.5 l/m2 of the vertical wall/column surfaces to soak the soil right up to the
bottom. The soil shall be tamped back into place after this operation.

and as recommended by the supplier, particularly when handling these chemicals in the form of
These chemicals are usually brought to the site in the form of emulsifiable concentrates. The
containers shall be clearly labelled and kept securely closed.
Particular care shall be taken to prevent skin contact with concentrates. Prolonged exposure to
dilute emulsions shall also be avoided. Workers shall wear clean clothing and wash thoroughly
with soap and water especially before eating and smoking. In the event of severe
contamination, clothing shall be removed at once and the skin washed with soap and water. If
chemicals splash into the eyes they shall be flushed with plenty of soap and water and
immediate medical attention sought.
The concentrates are oil solutions and present a fire hazard owing to the use of petroleum
solvents. There shall be no naked flames in the proximity during mixing.
Care should be taken in the application of chemicals/soil-toxicants to ensure that they are not
allowed to contaminate wells or springs.
11.7 Inspections
For the duration of the Contract, following the treatment, the Contractor shall perform annual
inspections of all buildings treated.
If during the inspections, or at any other time, live subterranean termite infestation or
subterranean termite damage is discovered and the soil and building conditions have not been
altered in the interim, the Contractor shall:
1 Excavate the soil and perform other treatment as may be necessary forelimination of
subterranean termite infestation;
2 Repair damage caused by termite infestation; and
3 Re-inspect the building approximately 180 days after the additional treatment.
In the event of a reappearance of termites within the building area due to defective materials
or workmanship or due to any other reason, the Contractor will carry out the necessary post
construction treatment to keep the entire area free from termites once again.
The Contractor shall maintain a Pest Management Maintenance Record, identifying target pest,
type of operation, brand name and manufacturer of pesticide, formulation, concentration or
rate of application used and submit copies of records when requested by the Employer’s
Representative.
12 Roads and Pavements
The construction and reinstatement of roads and parking areas shall be carried out in
accordance with the specifications for road works of the related areas.
12.2 A comprehensive network of roadways shall be provided around the treatment plant to link in

12.6 Setting Out
The Contractor shall provide all labour and materials such as lines, strings, pegs, nails, bamboo,
stones, mortar, concrete etc, required for setting out, establishing benchmarks and giving
profiles. The Contractor shall be responsible for maintaining the benchmarks, profiles,
alignments and other stakes and marks as long as they are required for the works.
The surface of the installed layers will be parallel and have the same grade as the designed
asphalt surface and all subsequent layers.
12.7 Earthworks for Roads
Profiles of road excavation shall be laid at 25 m intervals to conform to the required alignment,
sections, grades and side slopes and the lines of cuts shall be clearly marked.
The Contractor shall, on no account, excavate beyond the slopes or below the specified grade
on the drawings unless so directed by the Employer’s Representative in writing.
12.7.1 Preparation of Sub-grade
Immediately prior to the laying of the sub-base metal, the sub-grade shall be cleaned of all
foreign substances and vegetation etc. Any ruts or soft yielding patches that appear shall be
corrected and the sub-grade dressed off parallel to the finished profile. The camber of sub-
grade shall conform in shape to that of the finished road surface. Camber boards shall be used
to get the required section.
The prepared sub-grade shall be lightly sprinkled with water, if necessary, and rolled with a
power roller of 10-12 tonnes. The roller shall pass over the same area of the sub-grade a
minimum of five runs. Any undulations in the surface that develop due to rolling shall be made
good with approved earth and sub-grade re-rolled.
12.7.2 Sub-base
The sub-base shall not be constructed on a wet sub-grade.
The width of the sub-base course shall be 150 mm more on either side than that of the water-
bound macadam wearing course. The finished thickness of the sub-base course shall be
mm. The sub-base metal course shall be laid in two layers, each of thickness 120mm and
compacted to 80mm
(ii) Spreading and Rolling
The metal shall be spread uniformly and evenly upon the prepared base to a thickness of
mm. The spreading shall be done from stockpiles along the side of the roadway. In no case
shall the aggregates be dumped in heaps directly on the surface prepared to receive the metal
nor shall hauling over an un-compacted or partially compacted base be permitted. 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. No segregation of large or fine particles
shall be allowed and the coarse aggregates as spread shall be of uniform gradations with no
pockets of fine material.
Immediately following the spreading of the metal, rolling shall be started with three wheeled
power rollers of 10 to 12 tonnes capacity or tandem or vibratory rollers of approved type.
Rolling shall begin from the edges gradually progressing towards the centre. First the edges
shall be firmly compacted with roller running forward and backward. The roller shall then move
inwards in successive passes uniformly lapping preceding tracks by at least one half width.
Rolling shall be continued until the road metal has been thoroughly keyed and the forward
movement of stones ahead of the roller is no longer visible. A slight sprinkling of water may be
applied if necessary.
(iii) Application of Screening
After the metal has been thoroughly keyed and set by rolling, screening to completely fill the
interstices shall be applied gradually over the surface. These shall be dry at the time of
application. Dry rolling shall be carried out while the screening is being spread so that vibrations
of the roller cause them to settle in the voids. The screenings shall not be dumped in piles but
be spread uniformly by spreading motion of hand shovels.
The dry rolling shall be accompanied with brooming with hand brooms, wire brushes or both. In
no case shall the screenings be applied so fast and thick as to form cakes or ridges on the
surface in such a manner as would prevent tilling of voids or prevent the direct bearing of the
roller on the metal. These operations shall continue until no more screenings can be forced into
the voids in the metal.
(iv) Sprinkling and Grouting
The surface shall be copiously sprinkled with water, swept and rolled. Hand brooms shall be
used to sweep the screenings into voids and to distribute them evenly. The sprinkling,
sweeping and rolling operations shall be continued with additional screenings applied as
necessary, until the coarse aggregate has become well bonded and firmly set in its full depth
and a grout has been formed of the screenings. Care shall be taken to see that the underlying
layers do not get damaged due to the addition of excessive quantities of water during
construction. After the first layer of the sub-base has fully set, to the satisfaction of the
Employer’s Representative, the second layer shall be laid. The construction operation for the
second layer will be the same as that specified herein for the first.
12.7.3 Water-bound Macadam Course
(i) Preparation of Base
The base to receive the water bound macadam course shall be prepared to the specified grade
and camber and made free of dust and other extraneous material. Any ruts or soft yielding
places shall be corrected in an approved manner and rolled until firm.
(ii) Spreading Coarse Aggregate
The coarse aggregates shall be spread uniformly upon the prepared base and compacted to
The spreading shall be from stockpiles along the side of the roadway or directly from vehicles.
In no case shall the aggregate be dumped in heaps directly on the surface prepared to receive
the aggregate nor shall hauling over un-compacted or partially compacted base be permitted.
The surface of the aggregates spread shall be carefully checked with templates and all high or
low spots remedied by removing or adding aggregate as may be required. No segregation of
large or fine particles shall be allowed and the coarse aggregate, as spread, shall be of uniform
gradation with no pockets of fine material.
The coarse aggregate shall not normally be spread over more than three days in advance of the
subsequent construction operations.
Immediately following the spreading of the coarse aggregate, rolling shall be started with three
wheeled power roller of 10 to 12 tonne capacity of tandem or vibratory rollers of approved
types. The weight of the roller shall depend upon the type of aggregate and shall be subject to
the approval of the Employer’s Representative.
Except on super elevated portions where the rolling shall proceed from inner edge to the outer,
rolling shall begin from the edges gradually progressing towards the centre. First the edge/
edges shall be compacted with roller running forward and backward. The roller shall then move
inwards parallel to the centre line of the road, in successive passes uniformly lapping the
preceding tracks by at least one half width.
Rolling shall be discontinued when the aggregates are partially compacted with sufficient void
space in them to permit application of blinding. A slight sprinkling of water may be applied if
necessary. Rolling shall not be carried out when the sub-grade or sub-base is soft or yielding or
when it causes a wave-like motion in the sub-grade or base course.
The rolled surface shall be checked transversely and longitudinally with templates and any
irregularities corrected by loosening the surface, adding or removing necessary amounts of
aggregate and re-rolling until the entire surface conforms to the desired camber and grade. In
no case shall the use of blinding be permitted to make up depressions.
(iv) Application of Blinding
After the coarse aggregate has been rolled, blinding to completely fill the interstices shall be
gradually applied over the surface. These shall be dry at the time of application. Dry rolling
shall be done while the blinding is being spread so that vibrations of the roller cause them to
settle into the voids of the coarse aggregate. The blinding shall not be dumped in piles but be
spread uniformly in successive thin layers either by the spreading motion of hand shovels or by
mechanical spreaders or directly from trucks. Trucks operating for spreading the blinding shall
be so driven as not to disturb the coarse aggregate.
The blinding shall be applied at a slow and uniform rate (in three or more applications) to
ensure filling of all voids. The rate of spreading blinding shall not be less than 3.00 m3 or
4.50 m3 per 100 m2. This shall be accompanied by dry rolling and brooming with mechanical
brooms, hand brooms or both. In no case shall the blinding be applied so fast and thick as to
form cakes or ridges on the surface in such a manner as would prevent filling of voids or
prevent the direct bearing of the roller on the coarse aggregate. The operations shall continue
until no more blinding can be forced into the voids of the coarse aggregate.
The spreading, rolling and brooming of blinding shall be carried out on only such lengths of the
road which could be completed within one day’s operation.
(v) Sprinkling and Grouting
After the blinding has been applied, the surface shall be copiously sprinkled with water, swept
and rolled. Hand brooms shall be used to sweep the wet blinding into voids and to distribute it
evenly. The sprinkling, sweeping and rolling operations shall be continued with additional
blinding applied as necessary until the coarse aggregate has been thoroughly keyed, well
bonded and firmly set in its full depth and a grout has been formed of blinding. Care shall be
taken to ensure that the base or sub-grade does not get damaged due to the addition of
excessive quantities of water during construction.
(vi) Setting and Drying
After the final compaction of water bound macadam course, the road shall be allowed to dry
overnight. Next morning, areas missing blinding shall be filled with blinding as directed, lightly
sprinkled with water if necessary and rolled. No traffic shall be allowed on the road until the
macadam has set. The Employer’s Representative shall have the discretion to stop hauling
traffic from using the completed water bound macadam course if in his opinion it would cause
excessive damage to the surface.
Should the sub-grade at any time become soft or churned up with the sub-base metal or the
water bound macadam course, the Contractor shall remove the mixture from the affected
portion, reshape and compact the sub-grade and replace the removed section in accordance
with the foregoing requirements.
12.7.4 Tack Coat
(i) Preparation of Base
The base on which a tack coat is to be applied shall be prepared, shaped and conditioned to the
specific line, grade and cross section by repairing all potholes or patches and ruts. The
potholes shall be drained of water and cut to regular shape with vertical sides. All loose and
disintegrated materials shall be removed. The potholes shall then be filled either with (i) coarse
aggregate and screenings and compacted with heavy hand rammers or approved mechanical
tempers or (ii) premixed chippings binders (bitumen grade S 35/ S 65) content of 3 percent by
weight of total mix, after painting the sides and bottom of the holes with a thin application of
bitumen, or a combination of both (i) and (ii) as approved by the Employer’s Representative.
The surface shall be thoroughly swept and scraped clean and free of dust and other foreign
(ii) Application
The binder used for tack coat shall be bitumen of suitable penetration grade within S35 to S65
conforming to IS: 73. The binder shall be heated to the temperature appropriate to its grade
and as approved by the Employer’s Representative. The binder shall be sprayed on the
prepared base at the rate of 1.0 kg/m2. The binder shall be applied uniformly with the aid of
either self propelled or towed bitumen pressure sprayer with self heating arrangement and
spraying nozzle arrangement capable of spraying bitumen at the above specified rate and
temperature to provide a uniform unbroken spread of bitumen. The tack coat shall be applied
just ahead of laying asphalt macadam.
12.7.5 Asphalt Macadam
Prior to spreading of the asphalt surface, the water bound surface shall be swept clean to
remove blinding to expose the metal surface.
(ii) Application of Macadam
The bituminous macadam shall be laid by mechanical compactor and finisher, the final
consolidation being by means of power roller weighing not less than 10 tonnes. The finished
surface shall not vary by more than 12.5mm above or below the designed level and the average
thickness shall not be less than 65 mm after consolidation.
The grading, composition and characteristics of the bituminous macadam shall be as follows:
Aggregate Grading
IS Sieve Designation Percentage passing
Bitumen (Grade S 65) Content: 3.7% to 4.3% by weight of total mix.
The bituminous macadam may be prepared in a hot mix plant or the bitumen may be cut back
with a suitable solvent so that the heated cut back bitumen may be mixed with the
aggregate.In either case mixing shall be carried out in a power driven pugmill mixer and shall be
continued until all the aggregate is coated.
The Contractor shall ensure that the installation temperature is adequate during the rolling /
compaction of asphalt.
(iii) Protection of Pavement
During the period between initial compaction of the coarse aggregate and completion of the
seal coat, the surface shall be protected from all traffic other than that which is absolutely
essentialto its construction.
(iv) Premixed Seal Coat
After the full grout has been rolled, the interstices shall be completely filled with pre-coated
gritof the following composition.
Aggregate Grading
IS Sieve Designation Percentage passing
600 micron 25 –
Bitumen (Grade S 65) Content : 7% to 8% by weight of total mix.
The premixed seal coat may be prepared in a hot mix plant or the bitumen may be cut back
witha suitable solvent so that the heated cut back bitumen may be mixed with the aggregate. In
either case, mixing shall be carried out in a power driven pugmill mixer and shall be continued
until all the aggregate is coated.
The premixed seal must be brushed to fill in the interstices, additional material being applied
during rolling if found necessary. The quantity of premixed seal required for this purpose shall
be approximately 1.22 m3 per 100 m2.
(v) Liquid Seal
On the completion of consolidation, which may be assisted by opening the road to traffic, a
liquid seal coat of Grade 565 bitumen shall be applied at a temperature of between 163 C to
191 C (325 F to 375 F) at the rate of 1.25 kg/m2. The application of bitumen shall be
immediately followed with a cover coat of clean dry ¼ cubical chippings at the rate of 1.22 m3
per 100 m2. The surface shall then be rolled with a power roller weighing not less than
tonnes. The composition of this seal coat shall be as follows :
