Geotechnical Eng. Structures…Buried right Under your Feet…!!

Terzaghi says:(Father of Soil Mechanics)

Unfortunately, soils are made by nature and not byman, and the products of nature are always complex…

Natural soil is never uniform…Karl Terzaghi (1883-1963)

I. To prepare graduates in Civil Engineering for successful careers dealing with analysis, design and management of infrastructural projects both in India and Abroad. It must alsonhelp them to develop an intelligent understanding of the theoretical bases of various codal provisions in design, construction and maintenance.

II. To provide the students with a comprehensive and balanced understanding of the several branches of Civil Engineering such as Structural Engineering, Geotechnical Engineering, Transportation Engineering, Hydraulic and Water Resources Engineering, Environmental Engineering and Engineering breadth to create novel products and solutions for the real-life problems.

III. To provide opportunities to students to work in interdisciplinary projects across the various branches of Civil Engineering.

IV. To provide students with a sound foundation in mathematical and scientific subjects which are necessary prerequisites for a clear and sound understanding of Civil Engineering as a whole and to encourage those students who are motivated to go for Postgraduate programmes in the branch of their interest. Those wishing to enter services through competitive examination should also be encouraged.

V. To create an understanding among the student body the values of life-long learning and to inculcate in them professional ethics, moral values and social concern.
