It has been found desirable to codify the numerous architectural and building drawing ofhce practices followed in the various architectural and civil engineering departments, so that the drawings prepared in any office can be read without fear of misinterpretation. The purpose of this code is to establish certain conventions, in order to avoid confusion, increase speed and achieve quick identification wherever this is reasonably possible. This standard was originally published in 1967. The present revision has been undertaken with a view to updating the contents of the standard. The revision takes into account international drawing practices. In this present revision recommendations with regard to sizes of drawings, scales, line work, lettering and dimensioning and nomenclature of buildings have been aligned with international practice. Considerable assistance has been derived in the formulation of this code from the fJlowing standards published by the International Organization for Standardization: IS0 2595 : 1973 Building drawings - Dimensioning of production drawings - Representation of manufacturing and work sizes IS0 4067 ( 2 ) : 1980 Building and civil engineering drawings - Installations - Part 2 Simplified representation of sanitary appliance IS0 4C07 ( 6 ) : 198.5 Technical drawings - Installations - Part 6 Graphical symbols for supply w:iter and drainage systems in the ground IS0 4157 ( I 1 : !9SO Building drawing - Part 1 Designation of buildings and parts of buildings IS0 4157 ( 2 ) : 1952 Technical drawings - Construction drawings designation of buildings and parts of buildings - Part 2 Designation of rooms and other areas Ihls stancia~d d!m covers nomenclature of floors and storeys at present covered in IS 2332 : 1972 ‘Nume:iclature of foors and storeys’, consequently this standard is withdrawn. The present nomen- clature is based on international practice but the earlier provisions of IS 2332 : 1972 rerat~ug to mezzanine, galleries and basements have been retained.
