This paper discusses the requirements for developing Mobile Model-based
Bridge Lifecycle Management Systems (MMBLMSs). These new systems should
link all the information about the lifecycle stages of a bridge (e.g.,
construction, inspection and maintenance) to a 4D model of the bridge
incorporating different scales of space and time in order to record
events throughout the lifecycle with suitable levels of details. In
addition, MMBLMSs should support distributed databases and mobile
location-based computing by providing user interfaces that could be
used on thin clients, such as PDAs and tablet PCs, equipped with
wireless communications and tracking devices, such as a GPS receivers.
A prototype system developed in Java language is used to demonstrate
the feasibility of the proposed methodology for realizing these systems.
