Message from the Head of the Department

Civil Engineering, perhaps unarguably the oldest engineering discipline and covers a wide range of activities that support civilisation. Civil Engineers mainly deal the built environment, that defines the modern civilisation. As built environment and the natural environment affects each other, Civil Engineers need to have the expertise of the natural environment too. Our program is designed in such a way to produce Engineers that serve the civilisation with sustainable solutions. In this regard we prepare students for a successful career in industry, research, and academia.

Department provide students a comprehensive knowledge in all civil engineering domains, such as structural, geotechnical, hydraulics and hydrology, construction, traffic and transport and environmental engineering. Curriculum is designed to satisfy the requirements stipulated by the Institution of Engineers, Sri Lanka. Department has a strong academic staff base diversified in terms of gender, age, and universities where they obtained the academic qualifications. Also, most of the staff have working experience in local- state run and foreign universities. They are active in research and serves in many professional and scientific bodies. The state-of-the-art laboratories aid smooth delivery of the program, undergraduate and postgraduate and industry-oriented research works, and consultancy.

Civil Engineering department has formal collaborations with local, foreign, government and private organisations for a wide range of interests ranging from research, corporate social responsibility projects, consultancy and so forth, and some interests are with international appeal. As an example, the collaboration on mountain hazards with the prestigious Chinese Academy of Sciences works on fundamental and applied aspects of mountain hazards. Department has a strong publication record with over 20 papers in index journals with most in first quartile of best journals every year.

As the Head, I am pleased to say that our graduates managed to secure employment and graduate opportunities in reputed organisations in Sri Lanka and elsewhere. If you believe you have the passion in Civil Engineering, consider enrolling in our program.
