How to manage bridges and infrastructure with the help of a Bridge Management System and innovative digital systems for monitoring and maintenance

The latest catastrophic events affecting roads and other infrastructures have brought up again the issue of infrastructure maintenance and safety to the center of technical and scientific debate, with a compelling need of periodic checks and analyses on their state of conservation.

Bridge management system is an essential part of overall, long-term asset management to improve the safety of bridges and infrastructures, allowing you to quickly identify any problems and to intervene promptly to prevent accidents or even collapses.

Failure is not an option and for this reason, it is necessary to:

  • set up an accurate structure monitoring plan;
  • have the asset information database always updated;
  • have decision-making models that provide for appropriate intervention and maintenance strategies.

All these aspects can be managed with the help of a bridge management software, which also enables you to manage 3D BIM models, update data and information in real time, manage IoT sensors and plan the activities of technicians and operators involved in the entire process.

What is a BMS?

A Bridge Management System (BMS) is a set of tools, methodologies and processes used to effectively and efficiently manage the maintenance and management of bridges within a road or rail infrastructure. BMSs are essential to ensure the long-term safety, durability and functionality of bridges.

The Importance of Bridge Management Systems

Bridges are fundamental infrastructures to ensure mobility and connection between different geographical areas. However, weather conditions may cause damage to decks, which could compromise the safety of users. Therefore, it is crucial to constantly monitor the condition of bridges and plan appropriate maintenance interventions.

Main components of a BMS

A BMS includes several main components, including:

  • database of information on bridges, including for example their location, type of structure, age, state of conservation, etc.;
  • monitoring and analysis tools to collect and evaluate data on bridges;
  • decision models to determine priorities and maintenance strategies.

How a Bridge Management System works

Data collection process

The data collection process in a BMS involves the use of different monitoring and inspection techniques, such as:

  • visual inspections, in which engineers assess the condition of the bridges by observing them directly;
  • instrumental monitoring, which uses sensors and measuring devices to detect any deformation, corrosion or damage to the bridge structure;
  • non-destructive inspections, such as thermography, ultrasound or radiography, used to detect internal defects without damaging the bridge.

Data analysis and maintenance decisions

Once the data is collected, it must be analyzed to identify any problems or areas of degradation that require maintenance. The system can also predict the evolution of bridge conditions over time, based on mathematical and historical models. Based on this information, the BMS shall establish the most appropriate intervention priorities and maintenance strategies, taking into account available costs and resources.

To analyze data and build an informed and efficient decision-making process, you need to manage information with a bridge management software that enables you to:

  • store information in an orderly manner;
  • share the data with all the users involved;
  • have realtime updates;
  • view information directly on the BIM model;
  • manage IoT sensors directly from a smartphone;
  • have 3D models, reports, analyses, etc. available on the cloud;;
  • create and manage GIS maps complete with BIM models;
  • plan maintenance;
  • track activities and manage issues.

BMS: bridge management system with openBIM and GIS integration

 

BMS: a practical example

Now let’s take a look at how to proceed with the implementation of a BMS.

In order to structurally structure a BMS, it is necessary to start from the creation of a GIS map in GeoJSON format, using a BIM GIS software. You can insert the BIM models of your infrastructure project directly on the 3D map, that has been produced with any BIM software and then imported in open IFC format.

You can also digitize the entire sensor system for monitoring and associate it with properties, characteristics and technical information. All information is shared on the cloud and easily accessible to all team members. The territorial context on which the infrastructure is built can be represented in different ways and with different degrees of detail, in order to facilitate the analyses to be carried out also on the reference context. You can associate technical information and refer to the data attached to each model object. The amount of data that can be managed is considerable and the BIM GIS tool allows you to have everything under control and update the models over time.
