The collapse of the Schoharie Creek bridge drew attention to underwater inspection. Underwater inspection of bridges gives engineers a better understanding of the condition of the bridges. The underwater inspection consists of visual inspections, scour investigations and probings. The divers usually use scubea equipment, only needing surface supplied equipment at depths below 130 ft. Underwater inspection is relatively new and many state programs are presently forming. To adequately inspect the structures, the diver should be an engineer familiar with bridge inspection—a guideline that has led many firms to make divers out of engineers. The author is an engineer whose firms conduct underwater inspections.
