Course details

The Subsurface Exploration: Importance and Techniques Involved course provides a clear understanding of soil and rock conditions beneath the ground surface and their role in civil engineering projects. It explains why subsurface investigation is a critical step before the design and construction of foundations, embankments, tunnels, and other infrastructure works, helping to minimize structural risks and unexpected ground failures.

The course covers the planning and execution of site investigation programs, including direct and indirect exploration methods, drilling and boring techniques, in-situ testing, geophysical surveys, and groundwater assessment. It also emphasizes the interpretation of field and laboratory test results, development of soil profiles, and preparation of geotechnical investigation reports used for safe and economical engineering design.
