About this course
The development of Railways, Harbours, Metros, and Subways is vital for the growth and prosperity of a country, as they support the increasing movement of goods and people at national and international levels. Metro and subway projects in cities require the construction of long, deep tunnels beneath urban areas, demanding advanced design and construction practices. Globally, new materials, innovative techniques, and modern concepts are being adopted in these infrastructure works. Diploma Civil engineers in the transportation sector must be aware of these developments to ensure effective supervision and maintenance. Their role as technicians is crucial in the creation and management of such facilities. This course provides knowledge and skills related to construction and management of Railways, Harbours, and Tunnels. It equips students with technical abilities required in the transportation sector. By learning new materials and practices, they can perform their jobs effectively. Hence, this course is important for building competent engineers and technicians.
