A guide for the instruction of bridge inspectors is provided in this manual as well as instructions for conducting and reporting on a bridge inspection. The chapters outline the qualifications necessary to become a bridge inspector. The subject areas covered are: The Bridge Inspector, Bridge Structures, Bridge Inspection Reporting System, Inspection Procedures, Bridge Component Inspection Guidance, and Reports and Recommendations. The duties of an inspector and the requirements for his training are laid out in chapters one through four. Chapter five covers the construction and design aspects of bridges together with the explanation of mechanical principles. The nature and theory of bridge construction occupies approximately two thirds of the manual. The rest of the manual covers the inspection field book, inspection equipment, foundation movements and effects on bridges, the nature of underwater inspections, and structural bridge deficiencies. There are extensive diagrams, photographs, a glossary of bridge engineering and inspection terms, and a 62-item bibliography. (KP)
