| Abstract | Managers of mixed urban infrastructure assets in federal departments, provincial governments,municipalities, school boards, and universities, etc. have to manage a diversified set of built assets, from complex underground networks (e.g. water distribution, sewers) to buildings, roadway systems, parks, transit systems, and other assets collectively known as infrastructure. These built assets are subject to deterioration due to ageing, climate, geological conditions, or changes in use. Because of a lack of adequate funding and appropriate decision support technologies, certain components of our urban infrastructure have been neglected or receive only remedial treatments. Consequently, these built assets do not last their originally predicted service life, unless they undergo major rehabilitation and renewal. |
