E – 1529 Bridge Substructure and Superstructure Inspection

Description

The inspection of bridge substructure and superstructure components are discussed in this course. The course presents a detailed, systematic guide to the inspection of each bridge component. The guidelines provided can be used to help recognize, describe, and assess problems with the various components, particularly fracture critical members (FCM).

• Learn how to check for scour or erosion around the abutment and for evidence of any movement (sliding, rotation, etc.) or settlement;
• Learn how to check piers or bents for erosion or undermining of the foundation by scour and for exposed piles;
• Learn the importance of checking steel piers and bents for corrosion (rust, especially at joints and splices) including bolt heads, rivet heads, and nuts which are very vulnerable to rust, especially if located underwater or in the base of a column;
• Learn techniques for checking timber piles, caps, and bracing including presence of decay; and
• Find the best ways to inspect dolphins and fenders.
