Scope: How it Evolves
• Bridge
failures
• Bridge management
• Assessment/Inventory/Management
• Provide public w/ state and local government
financial position (infrastructure assets)
• Standard reporting approach
• Depreciation
• Modified reporting approach
• Inventory, Assessment, Maintenance
Scope:
Where it is Going
Prevent Deteriorating Records (GIS)
Inspect Street Subsystems, Alleys, Streets
Prevent Deteriorating Bridges
Using NDE to
augment internal
