Methods of Measurement of Works of Civil Engineering ( Excluding River Valley Projects)Sectional Committee, CBD 44

FOREWORD

This Indian Standard ( Part 8 ) (Fourth Revision) was adopted by the Bureau of Indian Standards.after the draft finalized by the Methods of Measurement of Works of Civil Engineering (Excluding RiverValley Projects) Sectional Committee bad been approved by the Civil Engineering Division Council.Measurement occupies a very important place in planning and execution of any civil engineering workfrom the time of first estimates to final completion and settlement of payments of the project. Themethods followed for measurement are not uniform and considerable differences exist between practicesfollowed by one construction agency and another and also between various Central and StateGovernment departments. While it is recognized that each system of measurement has to be specifi-cally related to the administrative and financial organizations within the department responsible forwork, a unification of the various systems at technical level has been accepted as very desirable,speciaUl as it permits a wider circle of operation for civil engineering contractors and eliminatesambiguities and misunderstandings arising out of inadequate understanding of various systems followed.

Among the various civil engineering items, measuremen t of buildings had been first to be taken up forstandardization and this standard having provisions relating to all building works, was first publishedin 1958 and was subsequently revised in 1964. In its second revision, the standard was issued in differentparts corresponding to different trades in building and civil engineering works. As a result, the secondrevision of this standard ( Part 8 ) was published in 1967 which was then revised in 1974.This fourth revision has been brought out to incorporate the changes found necessary in the light ofusage of this standard and suggestions made by various bodies implementing it.

For the purpose of deciding whether a particular requirement of this standard is complied with, thoftnal value, observed or calculated. expressing the result of a test or analysis, shall be rounded ott inaccordance with IS 2: 1960 'Rules for rounding off numerical values ( revised)'. The number of significantplaces retained in the rounded off value should be the same as that of the specified value in thisstandard.
