Technology In Bridge Inspections Can Help Extend Lifespan

Anghel Saligny Bridge

Thank you Icons Of Infrastructure in helping to build awareness of the importance of updating current bridge inspection methods. With the state of current infrastructure and budgets worldwide and the lack of public appeal to claiming credit for doing great inspection work, bridge and infrastructure inspection methods and services typically get thrown to the bottom of the barrel in terms of importance.

In the US., we do have biennial inspections. Every 2 years every bridge in the Nation Bridge Inventory needs to be inspected. 


This is far better than many other countries but the methods, techniques and technologies utilized were developed dozens of years ago, prior to the invention of the Iphone

Many of them have been updated, typically after a bridge collapse, human life is lost and public awareness shoots up. Its time to challenge these methods and incorporate modern technology to make them a mandatory part of how our infrastructure is inspected. Bridges, tunnels, dams, etc. are at an age now where its not about preventative maintenance but preventing the next catastrophe.

Very often, technology is bypassed in the crucial task of bridge inspections, and archaic inspection methods still hold sway. The result can only be a disaster waiting to happen.

Current infrastructure inspection methods are manual in nature, subjective and don’t provide enough quantitative data for the department of transportation or asset owners to properly manage maintenance and repairs.

Lane Closures cause traffic delays.

Crash trucks cause traffic accidents.

Inspectors can only inspect one side of sheathing.

Dangerous for the inspectors and the travelling public.

Most importantly the inspectors are inspecting the HDPE sheathing and not the actual steel holding up the bridge.   These bridges are conducted every two years in every state on every bridge in the US National Bridge Inventory. Approximately 650,000 bridges at the taxpayers expense. 

How To Save Our Infrastructure with technology and not tax dollars. 

By utilizing existing nondestructive testing and robotics to inspect bridges, we can help safely extend the service life of critical infrastructure assets worldwide. This technology exists and is in use today.  Imagine critical infrastructure assets that are inspected on a regular basis collapses and the technology existed to help prevent the collapse. 

By utilizing the latest nondestructive testing and robotic infrastructure testing services bridge project managers and asset owners can better manage their budgets for maintenance and repairs. This can not only prevent catastrophes but help extend the service life of critical infrastructure worldwide while saving billions in untimely replacements.
