“Don’t Replace Your Bridge Too Soon”

There is a great deal of technology and data science that can help extend track and bridge structure life. But the railroads are not always out in front in exploiting the opportunities. Engineers can see the practical uses of bridge “micro movement” sensor technology. But at the big executive table that allocates the budget resources inside railroads, identified economic opportunities point to the need for the chief financial officer and his or her risk management staff to get directly involved in examining the identified options not seen before sensor data analytics entered the tool box. Perhaps as many of one-half of all visual inspection-based bridge capex decisions are wrong. Why? Because the visual data entered into the sophisticated engineering spreadsheet formulas isn’t accurate enough.
