Goals for Bridge Inspection and Management
• Ensure safety, operational capability, and protect the investment efficiently
– Inspection is used as the eyes and ears of the program to find and document the current condition including any problems
– Management utilizes the inspection data along with the organization’s priorities to determine the most efficient way to ensure goals are met (i.e. safety, performance, capacity)

Technology + Bridge Industry
• Technology availability is different from industry adoption
Bridge Industry:
• Safety Focused
– Utilize only proven approaches
– Code/rule based
• Government agencies are primary entities
• Skilled Professionals
=> Changes are often slow to be implemented
