DESCRIPTION:
The latest changes to the National Bridge Inspection Standards (NBIS), which became effective January 13, 2005, require bridge inspection training for all divers conducting underwater inspections. One method of meeting this requirement is the completion of an FHWA-approved underwater diver bridge inspection training course. Satisfactory completion of this course will fulfill the NBIS requirement. A final examination based on course content will be administered to participants. This course also provides an overview of diving operations that will be useful to agency personnel responsible for managing underwater bridge inspections. Course topics include methods of underwater inspection, underwater material deterioration mechanisms and inspection techniques, scour inspection techniques, underwater element-level rating, and underwater bridge inspection training. OUTCOMES:
Upon completion of the course, participants will be able to:- Explain the need for and benefits of inspecting the underwater portions of bridge structures
- Describe typical underwater defects and deterioration and identify conditions contributing to rates of deterioration
- Identify the types of inspection equipment available and the advantages and limitations of each
- Identify procedures for planning and performing thorough and safe underwater bridge inspections
- Assign component- and element-level condition ratings for underwater components in accordance with NBIS and agency requirements
TARGET AUDIENCE:
Experienced divers who require a knowledge base of underwater bridge inspection and evaluation techniques in order to meet the educational requirements of the NBIS for underwater bridge inspection training. The course also will be of interest to managers, structural engineers, and non-diver bridge inspectors from the public and private sector. |
