There is much information needed to manage the activities and events
that occur throughout the lifecycle of an infrastructure system, such
as a bridge, including construction, inspection, and maintenance
activities, environmental effects, etc. Conventional infrastructure
management systems provide only limited support for representing and
visualizing this information. Using a 4D product model to visualize
information related to different stages of the lifecycle of structures
is a powerful method to understand the spatial and non-spatial
relationships between the components of the structure and the changes
over time of the attributes of these components. This paper discusses
an integrated framework for lifecycle infrastructure management
systems. This framework integrates information from different sources
and links it to the 4D model of the product. A prototype system is
developed in Java language to demonstrate the proposed approach using
the data of Jacques Cartier Bridge in Montreal.
