In April, Italy suffered another bridge collapse, causing increased scrutiny over the conditions of the country’s road bridges. Do you believe the recurrence reflects more on how the infrastructure is built, how Italian officials conduct routine inspections or both?

My suspicion is that Italy's infrastructure, and thus the safety of the public, suffers from the same disease that most countries suffer: failure elected government officials to heed the advice of engineering professionals about reported structure conditions and lack of will to resolve infrastructure problems, rather than toy in the political static that helps maintain them in power. As physical results prove, the bottom will drop from beneath them, and unnecessary human misery and death occur.

I'm fairly sure these two failed bridges were constructed properly...they stood for many years. However, as with all infrastructure, if you're not inspecting and maintaining it then time, wear and decay will catch up to it and it will fail.

It would appear that at least these two failed structures were properly constructed as designed. However the design of the structures requires some investigation and as usual, the devil will likely be found in the details. Durability of the design is often neglected in favor of reduced initial costs. As we accomplish our engineering designs with more reliance on computer modeling and the capabilities of hybrid or alloyed high strength materials and reduced excess capacity or redundancy. Construction and quality control become increasingly consequential. This all leads to the need for increased spending for structure maintenance and professional engineering inspection as we become more heavily dependent on the reliability of our inspectors than on the reliability of our structures.

As always with this problem we are dealing with the elephant in the room. These bridges have stood for years and have deteriorated significantly because of one thing ‘corrosion”. Corrosion of the structural steel, components, corrosion of the rebar, causing deterioration and premature failure of the structure. It seems in our discussions people like to talk around the cancer that is destroying these structures from the inside out. The inspectors see it, but it seems the owners are reluctant to respond to mitigating the corrosion issues with processes and technologies that actually have a chance to stop it. This cancer that's progressing through our aging infrastructure will continue to destroy the one thing that sets us apart from the third world and allows us to enjoy the lifestyles and freedoms of movement and economic liquidity that we have. The solution is simple focus on the corrosion issues with the proper chemistries and processes so that the corrosion is stopped. This can be done in a very cost effective and focused manner if the right processes and chemistries are put in place that can neutralize and stop the ongoing corrosion. The solutions need to be structure specific and focused on the level of deterioration and the causes of that deterioration on each individual structure. Only then will we embark on a viable restoration and rehabilitation process that will produce cost effective end results and give the asset owners (taxpayers) a guaranteed result.
