Civil engineers accompany the construction process from planning to completion, maintenance, and renovation. Typical projects include all types of the buildings and their technical features, tunnels, bridges, streets, and waterways.Civil engineers also create the foundations for an innovative, urban infrastructure including consideration of climate change and demographic changes. This is how, for example, infrastructure solutions for the supply and waste management of cities and mobility adaptations are optimized. They focus their attention on sustainability, energy efficiency, and resource conservation.
