A need for a consolidated handbook covering the methods of measurement of building works at a place has been felt by various organizations, in general, and the educational institutions, in particular. Such a handbook is also expected to help those organizations which are dealing with all the trades. This Handbook was first compiled in 1984 and was based on information given in various parts of IS 1200 as on 31 March 1984. This revision includes information as on 31 March 1987 which incorporates revised parts 13, 15, 17 and 23, and amendments issued to Part 21. However, for the purpose of exact latest information which is required to be referred in case of contracts, etc, reference may be made only to the relevant parts of IS 1200 instead of this Handbook.
