Terzaghi says:
(Father of Soil Mechanics)
Unfortunately, soils are made by nature and not by
man, and the products of nature are always complex…
Natural soil is never uniform…

PROGRAMME EDUCATIONAL OBJECTIVES (PEOs):
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.
Programme Outcomes: (POs)
a) Graduates will demonstrate a sound knowledge of basic mathematics and sciences as
building blocks of the Civil Engineering discipline.
b) Graduates will demonstrate ability to conduct tests, interpret the results and report them
in a professional format.
c) Graduates will demonstrate the ability to design Civil Engineering systems following
specifications and meeting individual requirements.
d) Graduates will demonstrate their ability as productive members of interdisciplinary
design teams.
e) Graduates will have the ability to identify problems and find solutions for them in the
most cost-effective manner.
f) Graduates will display an understanding of their professional responsibilities meeting
ethical standards.
g) Graduates will be able to communicate in both verbal and written forms and make
effective presentations.
h) Graduates will have the confidence to apply engineering solutions, addressing social
concerns.
i) Graduates will be capable of self-education and clearly understand the value of life-long
learning.
j) Graduates will demonstrate an understanding of the impact of Civil Engineering of
society in enhancing the quality of life of the people.
k) Graduates will be familiar with modern Civil Engineering professional software tools and
demonstrate their ability in applying them for the solution of design situations they face.
