What Is Civil Engineering?

Civil engineering is the design and construction of public works, such as dams, bridges and other large infrastructure projects. It is one of the oldest branches of engineering, dating back to when people first started living in permanent settlements and began shaping their environments to suit their needs.


Early engineers built walls, roads, bridges, dams and levees; they dug wells, irrigation ditches and trenches. As larger groups of people began living together in towns and cities, these populations needed reliable sources of clean water, the means to dispose of waste, a network of streets and roadways for commerce and trade, and a way to defend themselves against hostile neighbors.


Ancient civil engineering projects include the roads of the Roman Empire, the Great Wall of China, the cliff dwellings at Mesa Verde and Mayan ruins at Copan, Palenque and Tikal. Many early civilizations built monuments to their rulers or gods. These may have been simple mounds or truly remarkable achievements, such as the Pyramids of Giza and Stonehenge, whose construction by pre-industrial societies remains mysterious. The names of the engineers who designed these wonders are lost to antiquity.

Today, the public is more likely to remember the names of great civil engineering projects than the names of the engineers who designed and built them. These include the Brooklyn Bridge (designed by John August Roebling and son Washington Roebling), the Hoover Dam (John L. Savage), the Panama Canal (John Frank Stevens) and the Golden Gate Bridge (Joseph Strauss and Charles Ellis). One notable exception is the Eiffel Tower, named after Gustave Eiffel, the French civil engineer whose company built it.

 
What a civil engineer needs to know?

Today's civil engineers need in-depth understanding of physics, mathematics, geology and hydrology. They must also know the properties of a wide range of construction materials, such as concrete and structural steel, and the types and capabilities of construction machinery. With this knowledge, engineers can design structures that meet requirements for cost, safety, reliability, durability and energy efficiency. Civil engineers also need a working knowledge of structural and mechanical engineering.

These engineers can be involved in nearly every stage of a major construction project. That can include site selection, writing specifications for processes and materials, reviewing bids from subcontractors, ensuring compliance with building codes, and supervising all phases of construction from grading and earth moving to painting and finishing.

More and more, civil engineers rely on computer-aided design (CAD) systems; therefore, proficiency with computers is essential. In addition to speeding up the drafting process for civil engineering projects, CAD systems make it easy to modify designs and generate working blueprints for construction crews.

Civil engineering jobs & salary

The BLS states, "Civil engineers generally work indoors in offices. However, many spend time outdoors at construction sites so they can monitor operations or solve problems onsite." Most civil engineers employed in the private sector work for large construction contractors or as consultants. Government institutions that employ civil engineers include state transportation departments and the military.

Most civil engineering jobs require at least a bachelor's degree in engineering. Many employers, particularly those that offer engineering consulting services, also require state certification as a professional engineer. Additionally, many employers require certification from the American Society of Civil Engineers (ASCE). A master's degree is often required for promotion to management, and ongoing education and training are needed to keep up with advances in technology, equipment, computer hardware and software, building codes, and other government regulations.

According to Salary.com, as of July 2014, the salary range for a newly graduated civil engineer with a bachelor's degree is $55,570 to $73,908. The range for a mid-level engineer with a master's degree and five to 10 years of experience is $74,007 to $108,640, and the range for a senior engineer with a master's degree or doctorate and over 15 years of experience is $97,434 to $138,296. Many experienced engineers with advanced degrees are promoted to management positions or start their own businesses where they can earn even more.
