Underwater Bridge Inspection
Instructor-led Training (ILT)
TRAINING LEVEL: Basic
CLASS SIZE: Minimum: 20 Maximum: 30
The latest changes to the National Bridge Inspection Standards (NBIS), which became effective January 13, 2005, require FHWA-approved 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 4-day course will fulfill the NBIS requirement.
This course 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. A final examination based on course content will be administered to participants.
Upon completion of the course, participants will be able to:
Specifically, upon completion of the course, participants should be able to:
Explain the need 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.
The course is intended for trained 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 would also be of interest to non-diver bridge inspectors, and FHWA, state, and local agency structural engineers.
