the average ground level for the sectional lengths of the trenches.
2. Bottom width for excavation shall be measured as given in the foundation drawings and details
showing the width of bedding concrete only and hence side clearance if any will not be
measured separately. The contractor shall cover for this in his rates.
3. Battering of benching of excavation sides if required to be done shall not be measured
separately, that is the sides of excavation shall be treated as vertical for computing the quantity o
excavation. Contractor should cover for this in his rates
4. The following shall not be measured and the allowance for the same shall be made by the
Contractor
I Setting out of work and site clearance removal of shrubs etc.
Ii Excavation for insertion of planking and strutting.
Iii Removal of slips or falls in excavation due to any reason
whatsoever.

only as the excavation in "any kind of soil" and not as the excavation in any kind
of rock.
6 a) Where ordinary rock and hard rock are mixed, the two kinds of rocks shall
be stacked separately on even and level ground and measured in stacks. The net
measurement of the two kinds of rocks shall be arrived at by applying deduction
at 40% (forty percent) for voids. If the total of the net measurement of two kinds
of rock exceeds the measurement of mixture assessed by means of cross sectional
measurement then the volume of mixture shall be apportioned in the proportion of
the net measurements of two kinds of rock.
b) Where soil, ordinary rock and hard rock are mixed the ordinary rock and
hard rock shall be stacked separately and measured in stacks and their net
quantities determined as mentioned in 6 (a) above.
The measurement of the soil shall then be arrived at by deducting the net
measurement of rock from the total measurement of cutting.
7 Deductions in the case of fills :
Deductions in the case of fills shall be made as follows :
a) Ten percent deductions shall be made from actual measured cubic contents in all
cases of consolidated fills to arrive at net cubic measurements, except where the
consolidations is done by heavy mechanical machinery, in which case the
deduction shall be five percent.
b) No deduction shall be made in the case of consolidated fills in confined situations
like plinth filling below floors.
8 All excavated materials will be the property of the Owner.
68
9 If the excavated materials, rock, etc., obtained from the excavation are allowed to
be used in the work, the Contractor shall pay to the Owner at the market rate the
cost of such materials, unless otherwise mentioned "Free of Cost to the
Contractor" in particular items.

plinth etc., and the fillings shall be thoroughly consolidated layer by layer (not
exceeding 200m thick) ramming with heavy cast iron rammers with optimum
moisture in soil and watering upto saturation.
11 Work of pre-construction anti-termite treatment should be carried out through
renowned agency and member of Pest Control Association with guarantee period
of 10 years.
The name of the Pest Control agency proposed for pre-constructional anti-termite
treatment, should be mentioned.
12 Particular attention of the Contractor is drawn to the thorough consolidation in
layers required in back filling in sides and top of foundations within the building
area, as the heights of fillings further required on top of low lying areas in the plot
range upto 3.0 m underneath the plinth area of the building. Item (9) of Section

SECTION 10
ANTI-TERMITE TREATMENT
1. CHEMICALS: The chemicals used for the soil treatment shall be any one or a combination of the
following the concentration shown against each in aquous emulsion:
Chemicals (EC's) Concentration
Chlorpyriphos 1.0% (by weight)
2. TREATMENT OF COLUMN PITS, WALL TRENCHES AND BASEMENT
EXCAVATIONS: The bottom surface and sides (upto a height of 30 cm. from the bottom) of the excavation
made for column pits, trenches and basements shall be treated with the chemical
emulsion mentioned above at 5 litres per Sq.mtrs of surface area.
3. TREATEMENT TO BACKFILL EARTH
After the column foundations, wall foundations and retaining walls of the basement come
up, the back filling immediate contact with the foundation structure shall be treated with
the chemical emulsion at the rate of 7.5 litre/Sqm of the vertical surface of the
substructure of each side. The earth is usually returned in layers and treatment shall be
carried our in similar stages. The chemical emulsion shall be directed towards the
concrete or masonry surface of the columns and walls so that the earth in contact with
these surfaces is well treated with chemicals.
4. TREATMENT TO R.C.C. FRAMED STRUCTURES: The treatment in 2 and 3 above applies essentially to masonry foundations where there
are voids through which termites an seek entry in to the superstructure. Hence the
foundations require to be completely enveloped by a chemical barrier. In the case of
R.C.C. framed structures with columns and plinth beams and R.C.C. basements the
concrete mix is rich and dense (being 1:2:4 or M. 150 or richer), the termites are unable
to penetrate it. It is therefore unnecessary to start the treatment from the bottom of
excavation the treatment shall start at a dept of 50 cm .below ground level, except when
ground level is raised or lowered by filling or cutting after the foundations have been cast
in such cases the dept of 50 cm shall be determined from the new soil level resulting
from filling or cutting mentioned above and soil in immediate contact with the vertical
surface of RCC foundations. From this depth, the backfill around the columns, beams
and RCC basement walls shall be treated at the rate 7.5 litres Sq.mtrs. The other details
of the treatment shall be as laid down in 3 above.
5. TREATMENT TO SOIL ALONG EXTERNAL PERIMETER OF BUILDING : After the building is complete, the earth along the external perimeter of the building
should be rodded at intervals of 15 cm and to a depth of 30 cm. The rods should be
moved backward and forward, parallel to the wall to break up the earth and emulsion
80
poured along the wall at the rate of 7.5 litres per sq. m. of vertical surfaces. After the
treatment, the earth should be tamped back into place. Should the earth outside the
building be graded on completion of building, this treatment should be carried out on the
completion of such grading. In the event of filling more than 30 cm the external
perimeter shall extended to the full depth of filling up the ground level so as to ensure
continuity of the chemical barrier.
6 TREATMENT OF SOIL UNDER APRON ALONG EXTERNAL PERIMETER
OF BUILDING Top surface of the consolidated earth over which the aprom is to laid shall be treated with
chemical emulsion at the rate of 5 litres per Sq.mtrs. of the vertical surface before the
aporn laid. If consolidated earth does not allow emulsion to seep through holes upto 50 to
75 mm deep at 150 mm centres both ways may be made with 12 mm dia mild steel rod
on the surface to facilitate saturation of the soil with the chemical emulsion.
7 TREATMENT OF SOIL SURROUNDING PIPES,WASTES AND CONDUITS :
When pipes, wastes and conduits enter the soil inside the area of the foundations, the soil
surrounding the point of entry must be loosened around each such pipe, waste or conduits
for a distance of 15 cm. and upto a depth of 7.5 cm. before treatment is commenced.
When they enter the soil external to the foundations, they shall be similarly treated,
unless they stand clear of the walls of the building by about 7.5 cm. for a distance of over
30 cm.
11. TREATMENT FOR EXPANSION JOINTS
Expansion joints at ground floor level are one of the biggest hazards for termite
infestation. The soil beneath these joints should receive special attention when the
treatment under 5 is carried out. This treatment should be supplemented by treating the
expansion joints after the subgrade has been laid, at the rate of 2 litres per linear metre.
12. SPRAYING EQUIPMENT A Pressure pump shall be used to carry out spraying operations to facilitate proper
penetration of chemical into the earth.
13. The above specifications are in line the I.S. Code of practice for Antitermite Measures in
Building, IS 6313 (Part-II)-1981 (First Revision)
81
