  • Underwater Inspection and Evaluation of Bridge Structures: FHWA

    Credits: 3 PDH

    PDH Course Description:

    The Federal Highway Administration's Bridge Inspector's Reference Manual (BIRM) is a comprehensive manual on programs, procedures, and techniques for inspecting and evaluating a variety of in-service highway bridges. BIRM serves as the basis of a comprehensive National Highway Institute training program in bridge-safety inspection. The present course is based on BIRM's Section 11.3, Underwater Inspection. The course introduces the equipment, training, safety, and regulatory requirements of commercial diving-both self-contained (SCUBA) and surface-supplied (air)-as it relates to bridge inspections. Investigations of underwater bridge elements such as substructure units are mentioned, and various sounding devices for detecting scour are described.
