INTRODUCTION


Location of various facilities underground will be the order of the day in the immediate future to ensure sustainable life for future societies by providing necessary infrastructure to accommodate transportation, communication utility networks and complexes for handling, processing and storage of many kinds of materials. More so in urban areas which will have to accommodate large populations. Application of New technologies besides use of sophisticated equipment for underground construction works would be warranted for execution of works in a cost effective manner conforming to sustainable development. With rapid growth of underground structure anticipated, there will be evolution of new technologies and innovative construction practices.

Tunneling Association of India (TAI) is the Indian chapter of the International Tunneling and Underground Space Association of India (ITA) established in 1991, has been involved in dissemination of information about the latest technological development in the execution of tunnel and underground projects by encouraging planning of the use of subsurface and to promote advances in the preparatory investigations for tunnels, design, construction and maintenance of tunnels and also by organizing symposia, seminars, workshops, and training courses, both at national as well as international level, in liaison with international organizations.
