This manual is a model to be followed by bridge paint inspectors on how to perform inspection duties properly. To the maximum extent possible, we have followed the Federal Highway Administration's (FHWA) model specifications. However, we recognize that these requirements may vary individually according to different State or local Departments of Transportation. Given that most of today' s bridge-paint work is being done on existing steel, this manual is geared toward people working in the field on existing steel. Some of the principles we discuss may also apply to shop-painted steel; however, shop painting may require additional considerations that are beyond the scope of this manual.
