OpenIPDM: A Probabilistic Framework for Estimating the Deterioration and Effect of Interventions on Bridges

TL;DR

OpenIPDM is a software tool that models infrastructure deterioration, evaluates intervention effects, and estimates service life using visual inspection data, validated on Quebec bridges, aiding future infrastructure management.

Contribution

It introduces a probabilistic framework and interactive software for deterioration modeling and intervention analysis based on real-world bridge data.

Findings

Validated on Quebec bridge network data

Provides quantitative estimates of intervention effects

Generates synthetic data for model verification

Abstract

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.
