Civil engineering is the profession and discipline that designs, builds, and maintains infrastructure works like roads and highways, bridges, tunnels, dams, canals, and buildings. Civil engineering is the umbrella term that covers a wide array of sub-disciplines in engineering. These sub-disciplines include engineering centered on projects benefiting the environment, municipalities, transportation authorities, federal agencies, and others.
The presence of civil engineers stretches across many fields and industries. The scope of civil engineering projects includes both the public sector to the private sector. In the public sector, engineering projects range from city and state operations to federal initiatives. In the private sector, civil engineering can be done for homeowners up to international corporations. After military engineering, civil engineering is the oldest engineering discipline.
