About this course

Civil engineering structures such as buildings, bridges, dams, and pavements are designed to serve society for many decades. However, due to factors like environmental exposure, material deterioration, aging, overloading, poor construction practices, natural disasters, and lack of periodic maintenance, these structures may develop defects, cracks, corrosion, and other forms of distress. If these problems are not addressed in time, the safety, serviceability, and durability of the structures may be seriously affected. In the present scenario, many existing structures are reaching the end of their design life or are experiencing deterioration due to increasing urbanization and environmental impacts. Replacing these structures completely is often costly and impractical. Therefore, proper inspection, maintenance, repair, strengthening, and rehabilitation techniques are essential to extend the service life of structures and ensure their safe performance. If the structure gets dilapidated, then sometimes it needs to be demolished. This subject aims to provide diploma civil engineering students with fundamental knowledge about causes of structural deterioration, methods of condition assessment, non-destructive testing techniques, maintenance strategies, and modern repair and rehabilitation methods. Students will also learn about materials used for repair, corrosion protection techniques, crack repair methods, and retrofitting practices. The knowledge gained from this course will enable diploma engineers to assist in the inspection, maintenance planning, and rehabilitation of structures, thereby contributing to sustainable infrastructure management and public safety.
