Maintaining and managing bridge infrastructure is a critical responsibility of local city councils in Australia. The safety of citizens and the smooth flow of traffic are reliant on the proper functioning of these structures. In this blog post, we will discuss suggested methods for creating a proactive approach to maintain and manage bridge infrastructure within a local city council in Australia, as well as the three levels of bridge inspections and how drones and 3D models can assist with this process.

Step 1: A Comprehensive Plan
The first step in creating a proactive approach to bridge maintenance is to develop a comprehensive plan that takes into account the expected lifespan of each bridge and the anticipated maintenance requirements. This plan should be reviewed and updated regularly to ensure that it remains relevant and effective.
Step 2: Routine Inspection Schedule
The next step is to establish a routine inspection schedule for each bridge, as outlined in the Australian Bridge Inspection Guidelines. There are three levels of bridge inspections that must be conducted on a regular basis to ensure the safety of the structure and the people who use it.
The Types of Bridge Inspections To Perform
Level 1 Inspections
Level 1 inspections are visual inspections that should be conducted every year to identify any signs of damage or deterioration. These inspections should be carried out by a qualified inspector who has received training in bridge inspection techniques.
Level 2 Inspections
Level 2 inspections are more detailed than Level 1 inspections and should be conducted every three years. They involve a more in-depth assessment of the structure and may include non-destructive testing methods to identify any hidden defects or weaknesses.
Level 3 Inspections
Level 3 inspections are the most extensive and should be conducted every ten years. They involve a comprehensive assessment of the bridge, including the use of destructive testing methods to determine the strength and durability of the structure.
Step 4: Data Into 3D Models
To ensure that these inspections are carried out effectively, it is recommended that local city councils use drones and 3D models to assist with the inspection process. Drones equipped with high-resolution cameras and sensors can capture detailed images of the bridge’s surface, allowing inspectors to identify any bridge defects, signs of damage or deterioration. This data is then used to create 3D models of the bridge, which can be analyzed by engineers and preservation experts to identify any potential issues.
Using drones and 3D models can also help to reduce the risk of accidents and injuries during inspections. Inspectors can remain safely on the ground while the drones collect the necessary data, reducing the need for potentially dangerous and time-consuming manual inspections.
Step 4: Upgrades and Repairs
Another important aspect of bridge maintenance is to ensure that any necessary repairs or upgrades are carried out in a timely manner. It is recommended that local city councils establish a maintenance schedule for each bridge that outlines the expected lifespan of the structure and the anticipated maintenance requirements.
Regular maintenance can help to prevent more extensive and costly repairs in the future. It can also help to extend the lifespan of the bridge and ensure that it remains safe and functional for years to come.
The Responsibility of Local Councils
In conclusion, maintaining and managing bridge infrastructure is a critical responsibility of local city councils in Australia. By developing a comprehensive maintenance plan, establishing a routine inspection schedule, and utilizing drones and 3D models to assist with the inspection process, local city councils can ensure that their bridge infrastructure remains safe and functional for years to come. Regular maintenance and timely repairs can help to prevent more extensive and costly repairs in the future, as well as ensure the safety of the people who use these structures.
