The Implementing Recommendations of the 9/11 Commission Act of 2007: Risk Assessments on critical infrastructure and
key resources of the United States must be conducted.
In addition, a report shall also be prepared on the comprehensive assessments evaluating threat, vulnerability, and consequence.

Focus on Antiterrorism Vulnerability Assessment Risk Analysis Feasible Mitigation Measures (with cost)
TSA provides interface with bridge owner: scheduling and coordination
Three steps in process: 1 – Site survey 2 – Risk Assessment 3 – Report to TSA
Bridge and Tunnel Assessment Program for TSA
-
Step One: Site Survey Assessment
Data Collection Review of available
drawings and information
Completion of questionnaires
Conduct information gathering discussions
On-site survey

-
Step Two: Risk Assessment Vulnerability Analysis
Identify Threats Identify Vulnerable
Components Prioritize using
Component Risk Analysis (Phase Ia)
Develop Threat Scenarios
Risk Reduction Develop Protective
Measures Develop Mitigation
Measures Mitigated Component
Risk Analysis Mitigation Measures
Cost Estimates

Step Three: Report to TSA – Surface Division Individual Site Report
Phase I: Draft Report, USACE Internal Review Phase II: Draft Final Report, TSA / FHWA /
Stakeholder Review Final Report shared with Cleared Owner Personnel Enhanced Executive Summary Sent to Stakeholders
Unclassified SSI document. Redacted version of sections 1-4 of the classified report.

Mitigation Measures on Bridges, ASCE Journal of Bridge Engineering, James C. Ray, P.E. – ERDC WES March/April 2007
Tunnels: Leveraged Best Practices and recommendations from past work. Developed risk assessment method similar to bridge risk process (look and feel)
Risk Analysis Methodology

BUILDING STRONG®9
Bridge: One Risk Assessment Structure Risk Analysis Evaluate individual bridge components
since loss of life is prevented by protecting the structure (stability)Threats are VBIED, HEIED, NECD, VI, Fire
Tunnel: Two Risk Assessments Operational Risk Analysis (Closure) Evaluate tunnel components
and systems for “catastrophic damage” (Shut-Down of Operations)Threats are VBIED, HEIED, NECD, VI, Fire
Casualty Risk Analysis (Injury) Evaluate magnitude of casualties caused by attack
Threats are VBIED, Fire, Chemical
