Worth a read or reread from our very own DR back in 2009.

”The applications for CVM sensors can include such diverse structures as: buildings, bridges, trains and subway vehicles, mining structures, railroad cars, trucks and other heavy machinery, pressure vessels, oil recovery equipment, pipelines, steel transmission towers, ships, tanks and a wide array of military structures”

”In the matter of bridge refurbishment alone, the National Bridge Inventory Database (Fed. Highway Admin. 2003) indicates that 30% of the 600,000 bridges in the United States are “structurally deficient.” In addition, a majority of the rail bridges in U.S. are operating beyond their initial design life. A bridge that is “structurally deficient” is still strong enough and stable enough for use; however, closer scrutiny of the bridge is required to ensure its continued, safe operation. In 2006, the American Society of Civil Engineers (ASCE) issued a report on the status of the U.S. infrastructure. It assessed everything from roads to hazardous waste systems and gave the country’s infrastructure an overall grade of “D”
