What is civil engineering?

Civil engineering designs and builds infrastructure — roads, bridges, dams, buildings, water systems, and transit — that society depends on for shelter, transport, and utilities.

Exam tip: keep SI units consistent end-to-end, write the governing relation symbolically before substituting, and sanity-check magnitude and sign.

Understand the concept

Civil engineers work from site investigation through design, permitting, construction supervision, and asset maintenance. Sub-disciplines include structural, geotechnical, transportation, environmental, and water resources.

Typical projects

Highways, metro systems, airports, sewage treatment plants, skyscrapers, tunnels, and flood control systems. Projects must meet safety codes, budget, schedule, and sustainability goals.
