FOREWORD
Users of various civil engineering codes have been feeling the need for explanatory handbooks and other compilations based on Indian Standards. The need has been further emphasized in view of the publication of the National Building Code of India 1970 and its implementation. In 1972, the Department of Science and Technology set up an Expert Group on Housing and Construction Technology under the chairmanship of Maj-Gen Harkirat Singh. This group carried out in-depth studies in various areas of civil engineering and construction practices. During the preparation of the Fifth Five Year Plan in 1975, the Group was assigned the task of producing a Science and Technology plan for research, development and extension work in the sector of housing and construction technology. One of the items of this plan was the production of design handbooks, explanatory handbooks and design aids based on the National Building Code and various Indian Standards and other activities in the promotion of National Building Code. The Expert Group gave high priority to this item and on the recommendation of the Department of Science and Technology the Planning Commission approved the following two projects which were assigned to the Indian Standards Institution: a) Development programme on Code implementation for building and civil engineering construction, and b) Typification for industrial buildings. A Special Committee for Implementation of Science and Technology Projects (SCIP) consisting of experts connected with different aspects (see page v) was set up in. 1974 to advise the IS1 Directorate General for identifying and guiding the development of the work under the chairmanship of Maj-Gen Harkirat Singh, Retired Engineer-in-Chief, Army Headquarters and formerly Adviser (Construction), Planning Commission, Government of India. The Committee has so far identified subjects for several explanatory handbooks/compilations covering appropriate Indian Standards/Codes/Specifications which include the following: Functional Requirements of Buildings Functional Requirements of Industrial Buildings Summaries of Indian Standards for Building Materials* Building Construction Practices Foundation of Buildings Explanatory Handbook on Codes for Earthquake Engineering (IS : 1893-1975 and IS : 43261976)t Design Aids for Reinforced Concrete to IS : 456-1978t Explanatory Handbook on Mansonry Code?
