Author's vast experience has shown that more than 90% of engineers entering the profession do not adequately refresh or apply the academic knowledge gained during their student years. Therefore, the author felt that providing the basic technical aspects of civil engineering in the form of a book containing only questions and answers would undoubtedly help field engineers to improve the quality, stability, and durability of civil works. So, this book provides basic knowledge about Roads, Buildings and Bridges to refresh and update the knowledge of students, budding B.E/ M. Tech degree holders and practicing engineers.
