Abstract

There is much information needed to manage the activities that occur throughout the lifecycle of an infrastructure system, such as a bridge, including design, construction, inspection and maintenance activities. Conventional infrastructure management systems (IMSs) provide only limited support for representing, visualizing and analyzing the spatio-temporal relationships in this information, which could result in spatial constraints being ignored. Therefore, the spatio-temporal data should be integrated in the IMSs and be visualized and analyzed to improve the efficiency and usability of these systems. The objective of this research is to propose new approaches and methods for visualizing and analyzing spatio-temporal information during the lifecycle of infrastructure systems. By integrating 4D modeling with several information technologies, the new approaches facilitate spatio-temporal representation in a more accurate and easily understood way
