10. Bridge inspectors and engineers.
(a) Bridge inspections should be performed by technicians whose training and experience enable them to detect and record indications of distress on a bridge. Inspectors must provide accurate measurements and other information about the condition of the bridge in enough detail for an engineer to make a proper evaluation of the safety of the bridge. (b) Accurate information about the condition of a bridge should be evaluated by an engineer who is competent to determine the capacity of the bridge. The inspector and the evaluator are often not the same individual. The quality of the bridge evaluation depends on the quality of the communication between them.
11. Scheduling inspections.
(a) A bridge management program should include a means to ensure that each bridge under the program is inspected at the frequency prescribed for that bridge by a competent engineer. (b) Bridge inspections should be scheduled from an accurate bridge inventory list that includes the due date of the next inspection.
12. Special considerations for railroad bridges.
Railroad bridges differ from other types of bridges in the types of loads they carry, in their modes of failure and indications of distress, and in their construction details and components. Proper inspection and analysis of railroad bridges requires familiarity with the loads, details and indications of distress that are unique to this class of structure.
