Environmental risk to assets

A model-based data driven approach to evaluating environmental risks to assets. Like quantum mechanics risk can only be approximated becasue it is based on probabilities. Our Model-Based approach emphasizes the following to encourage thoughtful analysis and collaboration

• Consistency
• Repeatability
• Transparency

Risk values are a function of:

• Owner Costs
• User Costs
• Threat Probabilities
• Asset Condition

Risks are captured on a GIS map to be used in:

• Planning, 
• Concept reports, 
• Design, and 
• Maintenance.  

Risk Priority map and Risk Process Description

Additional risks not found in available data are identified by participants in the corridor planning or concept development processes

Risk Prioritization is based on:

• Risk * Criticality Criticality includes AADT, Truck Traffic, and Redundancy
• Return on Investment (ROI = Total Risk/ Replacement Cost)

Possible risk responses

• Improve Robustness by hardening an asset
• Improve Redundancy by adding alternative routes
• Improve Rapidity, and/or Resourcefulness by developing rapid response plans
• Accept the risk and respond as needed

High priority risks

• Are analyzed for hardening options to improve Robustness
• A Go No-Go decision process is applied to a potential hardening solution
• Recommended hardening improvements move into concept reports to acquire funding

This Model-Based Process provides value to planning, design, maintenance and project delivery.

The Emergency Fund Map displays the location of all projects that used any federal emergency funds during construction. The map is updated weekly. It is an input for the intermediate planning process and for the project development process.
