One of the oldest forms of engineering is civil and structural engineering, which involves the design, construction, and maintenance of the built environment. Engineers in this field are responsible for ensuring that the infrastructure around us, gets developed, is safe, meets our needs and improves our quality of life. This includes buildings, bridges, railways, tunnels, water distribution and waste management networks. As a civil engineer you could be involved in sustainable urban development, environmental protection, conservation of energy and water resources, or even geotechnical, hydraulic or transport engineering. You could even specialise in fields such as earthquake and blast-resistant technologies.
