The main focus of this area of research excellence will be on above-ground infrastructure, such as roads, bridges, buildings, etc. Later on, we will also include buried infrastructure such as water distribution networks, sewers, commuter tunnels, etc. Research efforts will be devoted to understanding and developing business economics of infrastructure rehabilitation and replacement, include lifecycle assessment and costing. Technological breakthroughs in terms of assessing remaining serviceable life of a structure as well as retrofitting and rehabilitation of aging infrastructure will be sought. Scientific explorations into the effects of environmental and user-controlled factors on various construction materials (e.g. concrete, steel, wood, masonry, etc.) will also be undertaken.
