Methods of Measurement of Works of Civil Engineering (Excluding River Valley Projects )
Sectional Committee, CED 44
FOREWORD
This Indian Standard ( Part 1) ( Fourth Revision ) was adopted by the Bureau of Indian Standards,
after the draft finalized by the Methods of Measurement of Works of Civil Engineering ( Fxcluding
~~;;c~,alley Projects ) Sectional Committee had been approved by the Civil Engineering Division
Measurement occupies a very important place in the planning and execution of any civil engineering
work from the time of first estimates to the final completion and settlement of payments for a
project. Methods followed for measurement are not uniform and considerable differences exist
between practices followed by different construction agencies and also between various Central and
State Government departments. While it is recognized that each system of measurement has to be
specifically related to administrative and financial organizations within a department responsible for
the work, a unification of various systems at technical level has been accepted as very desirable,
specially as it permits a wider range of operation for civil engineering contractors and eliminates
ambiguities and misunderstandings of various systems followed.
Among various civil engineering items, measurement of buildings was the first to be taken up for
standardization and this standard having provisions relating to building work was first published in
1958 and was subsequently revised in 1964. In its second revision. the standard was issued in
different parts corresponding to different trades in building and civil engineering works. The third
revision of the standard was published in 1974.
This fourth revision has been brought out to incorporate the changes found necessary in light of
usage of this standard and the suggestions made by various bodies implementing it.
For the purpose of deciding whether particular requirement of this standard is complied with, the
final value, observed or calculated, expressing the result of a measurement. shall be rounded off
in accordance with IS 2 : 1960 ‘Rules for rounding off numerical values ( revised)‘. The number of
significant places retained in the rounded off value should be the same as that of the specified value
in this standard.

Blasting ) - Rock or boulders which may
be. quarried or split with crowbars. This
will also include laterite and hard
conglomerate.
Hard Rock ( Requiring Blasting ) - Any
rock or boulder for the excavation of
which blasting is required.

round lying lo&e on the surface or embedded in
river bed. soil, talus, slope wash and terrace
material of dissimilar origin.
Hard Rock ( Blasting Prohibited) - Hard
rock requiring blasting as described

other agreed method.
NOTE - A broad classification of soil and rock
for earthwork suitable for conditions generally
occurring in practice has been provided where
necessary., further sub-classification may be done
lo suit Individual cases depending on the
properties of the substrate.
4 METHOD OF‘MEASUREMENT OR
VARIOUS TYPES OF EXCAVATION
4.1 The measurement of earthwork shall be done
in cubic metres, unless otherwise mentioned. The
measurements to be taken shall be those of the
authorized dimensions from which soil has been
taken out and shall be measured without
allowance for increase in bulk.
4.2 Excavation in Earthwork Including Rock
Cutting
The measurement of excavation in earthwork
including rock cutting shall be made as follows:
4
b)
cl
Where the excavation is in trenches or
from borrow pits in fairly uniform ground,
the measurements of cutting trenches or
borrow pits shall be made. ‘Dead men’ or
‘tell-tales’ may be left at suitable intervals
to determine the average depth of
excavation.
Where the ground is not uniform, levels
shall be taken before the start, after site
clearance and after the completion of the
work and the quantity of excavation in
cutting computed from these levels.
Where soft/disintegrated irock and hard
rock are mixed the measurement for the
total quantity shall be made by method (a)
and/or (b) given above. The hard rock
excavated shall be stacked and measured
in stack. The quantity of the hard rock
excavated shall be arrived at by applying
pre-accepted deductions ( stated as a per
centage ) for voids. From the total
quantity of the mixture the quantity of
hard rock excavated thus arrived at shall
be deducted to work out the quantity of
the soft/disintegrated rock excavated.
2
4
d
Where hard/dense soil, soft/disintegrated
rock and hard rock are mixed, the measure-
ment for the total quantity shall be made by
methods (a ) and/or ( b) given above. If
possible after the removal of the hard/
dense soil the levels of the exposed
rocks urface should be taken and the
quantity of the hard/dense soil removed,
worked out from the difference between
the original levels and new levelsS’. If this
is not possible the excavation should be
completed leaving[,tell-tales and from the
cross-section of these tell-tales, the area of
the hard/dense soil excavated should be
worked out and ihen the volume of the
hard/dense soil excavated arrived at.
Quantity of hard dense soil should then be
deducted from the total quantity of hard
rock and soft/disintegrated rock. The
quantities of hard rock and soft/disintegrated
rock should then be separated as in ( c)
above by stacking the hard rock separately.
Where soft/loose soil, hard/dense soil, soft/
disintegrated rock and hard rock are mixed,
the measurements of the entire quantity
shall be made by methods ( a ) and/or ( b )
given above. The separate quantities of
soft/loose soil and hard/dense soil shall be
worked out from the cross-section based on
dead men or tell-tales as mentioned in ( d )
in case of hard/dense soil. The total
quantity of soft/loose and hard/dense soil
shall then be deducted from the total ex-
cavation to arrive at the total quantity of
rock excavated. The quantities of soft/d&
integrated rock and hard rock excavated
&oykecl out separately as in case of ( c)
4.2.1 WhereLer it is not possible or convenient
to take measurements from borrow pits or cutting,
excavation shall be worked out from ‘6Iling’
( see 4.3 ).
4.2.2 Dressing or trimming sides of excavations
and levelling or grading and ramming of bottoms
shall be described with the item of excavation
except in the case of rough excavation ( see 4.5 1.

successive stages of 1’5 m stating the commencing
level. This shall not apply toffcases where no
lift is involved as in hillside cutting.
4.2.4 All excavation shall generally be described
as ‘excavate and get out’. Getting out shall
include throwing the excavated earth at least one
metre or l/3 depth ( see Note ) of excavation
whichever is more clear of edge of the excavation.
The subsequent disposal of surplus excavated
material shall either be stated as a separate item
or included with the item of excavation stating
the lead.
NOTE - In special cases where disposal area is
limited or where application of this requirement is
impracticable, the person in-charge may adopt a berm
of reduced width in any case not less than 600 mm
provided the material being excavated is sufficiently
stable and shoring is designed to carry the additional
loads.

4.2.5 In case of the following works,
quantities ( calculated on the basis of
working space ) or those actually
whichever, are less, shall be measured:
authorized

b) In work which will be covered externally
with a damp proof covering;
c) In work which will be covered externally
with protective masonry work of brick,
stone, precast concrete, etc; .

ed concrete ground beams;
e) Special works like guniting, etc; and
f) In work which requires workmen to operate
from outside.
4.2.5.1 Authorised working space shall be special
in each case. Where authorised working space
is not so specified the following shall apply:
600 mm measured from the face of sub-
structure ( including protective measures, if
any) at lowest level, where extra working
space is required. In addition, for item (d )
given in 4.2.5 (d ) the extra length at each
end shall be I’5 m.
4.2.6 Battering and benching shall be specified
and measured along with main item of excavation.
4.3 Filling
4.3.1 Actual measurement of fill shall be calculat-
ed by taking levels of the original ground before
start of the work after site clearance and after
compaction of the fill at suitable intervals and
the quantity of fill computed from these levels.
4.3.2 Deductions shall be made from actual
measurements.in all cases of fills except for floors
as in 4.12 to arrive at net measurement of filling
based on pre-accepted or specified deduction
( stated as percentage ) for voids.
4.3.3 If the filling is obtained from the borrow
pits it shall be measured from the.borrow pits as
‘excavation’ ( see 4.2 ).
4.4 Surface Dressing
Trimming of natural ground, excavated surface
and filled up area to remove vegetation and/or
small inequalities not exceeding I50 mm deep
shall be described as surface dressing and
measured in square metres.
