• Inventory information
– Average Daily and Truck Traffic, geometry, location, and type
• Condition data
– NBEs, BMEs, ADEs, and NBI Condition Ratings
• Preservation and rehabilitation activities
• Cost data
– Preservation costs, rehabilitation costs, and annual budget
Analysis Components
10/15/2015 9
• Threshold triggers for condition-based actions
– Total needs for condition-based preventive maintenance activities

Needs Results Component
• Total needs = Cyclical + Condition-based + Rehabilitation
• Total needs of bridge preservation program are based on:
– Inventory
– Condition
– Cost
$500,000 + $900,000 + $1,000,000 $2,400,000 =
