  This paper describes OpenIPDM software for modelling the deterioration
process of infrastructures using network-scale visual inspection data. In
addition to the deterioration state estimates, OpenIPDM provides functions for
quantifying the effect of interventions, estimating the service life of an
intervention, and generating synthetic data for verification purposes. Each of
the aforementioned functions are accessible by an interactive graphical user
interface. OpenIPDM is designed based on the research work done on a network of
bridges in Quebec province, so that the concepts presented in the software have
been validated for applications in a real-world context. In addition, this
software provides foundations for future developments in the subject area of
modelling the deterioration as well as intervention planning.
