Civil engineers are becoming more and more important with time. Now, they are also responsible for looking after the fire control systems and installing quick fire exit points in the buildings they design. This will help in minimizing the loss of life during fire accidents. Civil engineering is one of the oldest of the engineering professions. Ancient feats such as the building of the Egyptian pyramids and Roman road systems are based on civil engineering principles. Another very important aspect of civil engineering is environmental engineering. In this case, the civil engineers are concerned with applications of various methods to purify the contaminated air, water and soil. The polluted system should be cleaned, the waste extracted and the purified constituent must be sent back to the natural system.
Civil engineers are also responsible for building good quality transportation systems like highways, airports, rail lines, sea ports, etc. A civil engineer is concerned with determining the right design for these structures and looking after the construction process so that the longevity of these structures is guaranteed after completion. These structures should also be satisfactory for the public in terms of comfort.
