Abstract:As part of a cooperative agreement between the Tennessee Department of Transportation and the Federal Highway Administration, a study was conducted to evaluate current levels of digital camera and color printing technology with regard to their application to bridge safety inspection. The results, which are further detailed in this report, generally show that current digital technology is capable of replacing conventional bridge photography methods. Recently introduced digital cameras, such as the Kodak DC-120, are fully capable of capturing bridge inspection photographs in sufficient detail to support a safety and engineering evaluation. Color printing technology, such as that found in color laser and advanced color inkjet printers, is also adequate for the production of color prints. Furthermore, the cost of these systems has fallen to the point that, in many cases, the cost of buying the new equipment and of training inspectors in its use, is more than offset by the resulting savings in labor and materials cost. However, each State and/or Government agency needs to evaluate these costs in light of their own particular circumstances.
