FOREWORD This Indian Standard ( Part XII ) (Thir& Revision ) was adopted by the Indian Standards Institution on 14 May 1976, after the draft finalized by the Civil Works Measureqent Sectional Committee had been approved by the Civil engineering Division council . Measurement occupies a very important place in ~planning and execution of any civil engineering work from the time of first estimates to final completion and settlement of payments of the project. The methods followed for Measurement are not uniTorm and consider- able differences exist between practices followed by one construction agency and another and also between various Central and State Government departments.

6 While it is recognized that each system of Measurement has to be specifically related to the administrative and financial organizations within the department responsible for work, a unification of the various systems at technical level has been accepted as very desirable, specially as it permits a wider circle of operation for civil qgineering contractors and eliminates ambiguities and mis- understandings arising out of inadequate understanding of various systems followed. Among the various civil engineering items, Measurement of Building had been first to be taken up for standardization and this standard, having provisions relating to all Building works, was first published is 1958 and revised in 1964. In the course of usage of this standard ( IS : 1200-1964* ) by various construction agencies in the countiy, several clarifications and suggestion for modifications were received and as a result of study, the Sections, Committee decided that its scope, besides being applicable to buildinga shall be expanded so as to cover civil engineering ~works like industrial and river valley project works.

7 *iMethod of Measurement of Building works ( rcvisrd ). IS t 1200 ( Part XII) - 1976 Since various trades are not related to one another, the Committee decided that each type of trade as given in IS: 1200-1964 be issued separately as a different part which will be helpful to specific users in various trade>. This part covering Method of Measurement of plastering and pointing appiicable to Building as well as civil engineering works was, therefore, issued as a second revision in 1971. In the course of use of this standard in the past five years based on the suggestions received, certain amendments were issued to this standard. This third revision also incorporates all those amendments. For the purpose of deciding whether a 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 : 2-1960t. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

8 1. SCOPE This standard ( Part XII ) covers the Method plastering and pointing for buildings and other civil 2. GENERAL RULES of Measurement of engineering works. Clubbing of Items-IItems may be clubbed together provided detailed drawings or specifications or both are prepared for such items and Method of Measurement is agreed to be on the basis stated in the standard. Booking of Dimensions-In booking of dimensions, the order shall be consistent and generally in the sequence of length, breadth or width and height or depth or thickness. Description of Items--Description of each item shall, unless .otherwise stated, be held to include, wherever necessary, conveyance; delivery; handling; unloading; storing; necessary scaffolding; protective cover; cleaning stains from floors, walls, return of packings, etc; and other incidental changes. Dimensions-- All work shall be measured net as executed in the decimal system, as given below: a) Dimensions shall be measured to the nearest m, and b) Areas shall be worked out to the nearest 0 01 ma.

9 * Method of Measurement of Building works ( mired ). *Rules for rounding off numerical values ( revised ). 4 IS: I200 (Parr XII ) - 1976 Bills of Qmntities - Items of work shall fully describe materials and workmanship and accurately represent the work to be executed. Preparatory Work- Preparatory work, such as raking out joints, scarifying and cleaning, shall be included in the description of item unless otherwise specified. 3. PLASTERING Plaster work shall be classified according to the material used and each classification shall be measured separately. The following parti- culars shall be given for each classification: 4 b) 4 4 4 f> Mix of mortar; Number of coats and thickness of each coat; Nature of surface treatment, Nature of base; Curved work, conical work, spherical work and eliptical work stating the radius; and Any special treatment of base. Description shall include arrises, internal rounded angles, external chamfers and/or rounded angles not exceeding 80 mm in girth.

10 NOTE - For work exceeding 80 mm girth, scc In case of fibrous plaster, particulars of methods of application and of treatment of joints shall also be given. Work in repairs shall be so described stating thickness of dubbing, if any. Plastering on roofs, ceilings and walls shall be measured separately. Removing plaster by scraping or otherwise shall be measured separately in square metres. Plastering in isolated widths or in widths not forming part of general plastering work ( as in bands, cornices, sunk, panels, etc) and in chamfers, rounded angles exceeding 80 mm in girth shall be measured a~ below: a) 30 cm or below in width/girth, in running metres; and b) above 30 cm in square metres. Plastering at a height greater than 10 m above ground/datum level shall be measured separately in stages of 5-m height except interior plastering in case of Building which shall be measured separately for each storey. 5 W t 1269 ( Part XII ) - 4976 All plastering shall be measured in square metres unless otherwise described.
