Who Should Attend?

This 02 day program will help professionals, engineers, geotechnical engineers and geo-scientists dealing with trenchless projects. The program will also help project owners hiring services of geophysical surveys, enabling them understand capabilities and limitations of various methods and derive maximum return on their investment on a geophysical survey.


The program will enable the participant to derive maximum information from geophysical investigation program and help them design the right investigation program for a particular project requirement. It will also enable them to choose the right combination of techniques for varied geological conditions. The state-of-the-art subsurface geophysical investigations are helpful towards minimizing involvement of the conventional direct exploration methods, aiding in accelerated and economical development of projects.

About Training Workshop


Various latest technologies including Trenchless Technology are being used for creating and maintaining subsurface infrastructure in India at an increasing rate. The successful use of these technologies, and benefits in terms of speed and least inconvenience to people, are well known. 

Data on soil profile, rock, local heterogeneities and subsurface conditions is critical for safe and successful execution. There exist various geophysical techniques capable for providing these subsurface data in quick, totally non-destructive and economical manner. These advanced technologies can very effectively be used to handle the present day complex problems related to optimum utilization of available resources and infrastructure.

Engineering geophysics is an efficient means of subsurface investigation. The merit of application of this low cost aid lies in its ease of deployment and rapidity in providing a reliable knowledge of the underground over a large area, substantiating the requisite geotechnical evaluation studies thereby. Technological advancements and development of portable digital data acquisition instrument systems have increased the versatility in evaluating underground conditions and site characterization.

Geophysical tools such as Ground Penetration Radar (GPR), Seismic Refraction, Seismic Reflection, Electrical Imaging etc., can be used for the accurate mapping of the underground infrastructure facilities (Electrical & telecommunication cables, pipelines etc.), soil-rock interface, geological identification of soil, water table mapping, dimension of a sub stratum, elastic properties of the medium, geometry of various layers and other subsurface features. 

The workshop is aimed at familiarizing participants with these advanced geophysical investigations techniques including principle, field procedures, data processing & interpretation, capabilities, limitations and selection criteria for techniques suitable for diverse geological conditions. 


The full potential of geophysics for site investigation in India is yet to be fully realized. The incorrect and inappropriate use of geophysics has over the years caused a great deal of damage to its reputation as a bona fide and reliable technology. The objective of this workshop is to familiarize participants with details of various available techniques and empower them with required knowledge to plan/ execute/ supervise geophysical investigation program for trenchless project site investigations. The program will also cover quality control and quality checks on data, ensuring quality results are obtained from geophysical program. 

Learning Focus
