Method of Measurement of Works of Civil Engineering ( Excluding River Valley Projects ), CED 44

FOREWORD
This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized
by the Method of Measurement of Works of Civil Engineering ( Excluding River Valley Projects )
Sectional Committee had been approved by the Civil Engineering Division Council.
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 pavements of projects.
Methods followed for measurement are not uniform and considerable
difference exist between
practices followed by different construction agencies and also between various Central and State
Government
Departments and their undertakings. 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 the various systems at technical levels has been
accepted as very desirable, specially as it permits a wider range of operation for civil engineering
contractors and eliminates ambiguities and misunderstandings
arising out of inadequate understanding of various systems followed.
Since different trades are not related to one another, the Sectional Committee decided that for each
separate standards shall be issued as different parts as it would be helpful to users in using the
specific standard. This Part 28 covers method of measurement of sound insulation on work applicable
to building as well as to civil engineering work.
Sound insulation work is required to be done in some of the insulation buildings. The method of
measurement of insulation varies from organization to organization. The technical committee responsible for formulation of this standard has, after considering practices being followed by some of the
major organizations, decided to prepare this standard which adopts simplest type of measurement.
For the purpose of deciding whether a particular requirement
the final value, observed or calculated, expressing the result of a
accordance with IS 2 : 1960 ‘Rules for rounding off numerical
significant places retained in the rounded off value should be the
in this standard.

of this standard is complied with,
