7 FOREWORD This Indian Standard ( First Revision) was adopted by the Indian Standards Institution on 28 December 1979, after the draft finalized by the Soil Engineering and Rock Mechanics Sectional Committee had been appro- ved by the Civil Engineering Division Council. A detailed investigation for site is essential before a design can be fina- lized. The object of subsurface and related site investigation is to provide the engineer or architect with as much information as possible about the existing conditions,* for example, the exposed overburden, the course of a stream nearby, a rock outcrop or a hillock, vegetation, and other geological features of the area. It is equally important to know the subsoil conditions below a proposed structure.

8 The methods of subsurface investigation enable vertical sections of the strata to be drawn and samples to be tested, on the site or in a labora- tory for determining shear strength parameters, bearing capacity of the soil, permeability, water table, type classification and other geophysical informa- tion in the field. This information, together with the normal topographical survey, provides the engineer with complete details of the site and enables him to prepare economical designs for the foundations. Proper inspection and guidance in boring operations and investi- gations are essential to ensure that the required data are obtained. Because of the complexity of natural deposits, no one method of exploration is best for all situations.

9 The choice depends upon the nature of the material and on the purpose of the exploratory programme. This code is intended to summarize in a convenient form the information available so that the desirable information may be obtained. The code has been prepared in relation to conditions and practices existing in India. This standard was published in year 1962. Based on further data collected in past 18 years, this revision has been prepared. Though this code is mainly intended to cover subsurface investigation for foundations of multi-storeyed buildings, most of the provisions are 3 1s : 1892 - 1979 generally applicable to other civil engineering works, such as roads! air fields, bridges, marine works, etc. The following codes have been published so far to cover special aspects of investigation for specific works: *IS : 4078-1980 Code of practice for indexing and storage of drill cores (first revision ).

10 *IS : 4453-1980 Code of practice for exploration by pits, trenches, drifts and shafts (first revision ). *IS : 4464-1967 Code of practice for presentation of drilling informa- tion and core description in foundation investigation (jirst revision ). IS : 4651 (Part I )-1974 Code of practice for planning and design of ports and harbours : Part I Site investigation (first revision ). IS : 5313-1980 Guide for core drilling observations (first revision ). *IS : 6926-1972 Code of practice for diamond core drilling for site investigation for river valley projects. *IS : 69551973 Code of practice for subsurface exploration for earth and rocktill dams. In the formulation of this standard, due weightage has been given to imernational co-ordination among the standards and practices prevailing in different countries in addition to relating it to the practices in the field in this country.
