The International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) constituted a Technical Committee (TC) on Forensic Geotechnical Engineering (FGE) in 2005. During the first four years it was designated as TC40 and is now designated as TC302. This committee has already conducted three international seminars on FGE and is now organizing the fourth seminar during January 10-12, 2013 at Bengaluru (formerly known as Bangalore), India. The theme of the seminar is “Forensic Geotechnical Engineering” and is divided into ten topics as given in the themes section. During this three days seminar, these ten topics will be discussed in ten sessions.
Forensic geotechnical engineering involves scientific, legalistic investigations and deductions to detect the causes as well as the process of distress in a structure, which are attributed to geotechnical origin. Such a critical analysis will provide answers to “what went wrong, when, where, why, how, and by whom”. Cases of remedied installations, particularly those which, fall under public / or government category, where the analysis and evaluation of adopted remedial measures with regard to their effectiveness and economy may be subjected to judicial scrutiny also, fall under this purview. It also gives strong inputs to improve future designs. The normally adopted standard procedures of testing, analysis, design and construction are not adequate for the forensic analysis in majority of cases. The forensic investigations involve fresh field and laboratory tests apart from collection of all available data. The test parameters and design assumptions will have to be representative of the actual conditions encountered at site. While the designs are mostly stress based, the forensic analysis has to be deformation based. The forensic geotechnical engineer (who is different than the expert witness) has to be not only thorough in his field of specialization, but also be familiar with legal procedures. This seminar highlights the principles of planning and executing a forensic investigation citing case histories.
Indian Geotechnical Society
The Indian National Society of Soil Mechanics and Foundation Engineering was established in the year 1948, soon after the second International Conference on Soil Mechanics and Foundation Engineering held at Rotterdam. The Society was affiliated to the International Society in the same year and since then it has strived to fulfil and promote the objectives of the International Society. In December 1970, the name, Indian Geotechnical Society (IGS) was adopted. In January 1994, it hosted XIII International Conference on Soil Mechanics and Foundation Engineering. Various Local Chapters of the IGS organise annual conferences of the Society.
American Society of Civil Engineers (ASCE) India Section (IS)
American Society of Civil Engineers (ASCE) has been a front runner in the advancement of knowledge in the area of Civil Engineering globally and made significant contributions. The India section of ASCE is an initiative of International division of ASCE to spread its message and bring together many members from India to actively participate in its programs. The activities are spread across northern, eastern and southern regions of India.
Indian Institute of Science Bangalore
Established in 1909, Indian Institute of Science is widely recognized to be the best and most scientific and engineering institute for advanced research in India. Banglore is located on the Deccan Plateau in the south eastern part of Karnataka and is India’s fifth most populous urban agglomeration. It is a home to heavy industries, aerospace, techno communications and defence organizations and is also known as Silicon Valley of India. There are a lot of historical places in close proximity as well.
