Today many civil engineers design not structures but software systems to manage construction. They practice in the global market place being involved in the planning, designing and construction of infrastructure, balancing development with care for the environment. New fields and areas of civil engineering practice and research have emerged, involving the planning, design, construction and management of our man-made living habitat which is constantly evolving. New challenges facing civil engineering, such as our changing population profile, rising energy costs and climate change have arisen.
