The typical inspection begins with a review of the bridge history as well as prior reports and to identify pre-existing condition and define scope. A project management plan is then developed to define the inspection procedure as well as determine team members, safety requirements, equipment and quality control needs.
The approach roadway, deck, superstructure, substructure, and channel are then inspected and evaluated both visually and with hand tools. Fracture critical members are inspected hands-on, full length. The thickness measurements of questionable steel members are recorded with ultrasonic thickness gauges.
A scope of work is then developed for any necessary underwater inspections. Then, a report is prepared and all data is recorded in Corps of Engineers Bridge Inventory System (CEBIS). Typical data includes: structural inventory and appraisal, commonly recognized element data, critical inspection data for all components, recommendations for future action, cost estimate for recommended repairs, inspection drawings and photographs.
Finally, an Independent Technical Review is conducted.
