The Challenge

“The Final Four”

Take Care of What We Have

Make the System Work Better

7 Steps to Asset Management Implementation

1. Inventory2. Condition Assessment3. Targets4. Deterioration Curves5. Maintenance Strategies 6. Cross Asset Optimization7. Projects

Culvert Inventory

• Inventory is the First Step in Asset Management

MSE Walls

• Inventory Completed

• Condition Determined

• Next Phase

– Establishment of Targets

– Integrate with

Department’s Asset

Optimization Database

Bridge

• Inventory Completed

Every Two Years

• Condition Assessment

Determined at Element

Level

UDOT Strategic Goals

• Pavements that are in good condition today can be maintained by

an appropriate mix of maintenance and preservation treatments that will maximize the system Overall Condition Index (OCI) and prolong the pavement life.

The level of funding to obtain the optimal condition level (point of diminishing marginal return) was found to be $60 Million for the Interstate (increasing to $80 million), $50

million for the Level 1 NHS, $60 Million for the Level 1 non-NHS, and $90 million for the Level 2 system, for a total of $260 to $280 Million per year.
