Case Study of Bridge and Tunnel TVAs: Since the Blue Ribbon Panel Recommendations for Bridge and Tunnel Security Were Issued
As an original member of the Blue Ribbon Panel (BRP) that developed the "Recommendations for Bridge and Tunnel Security" published in September 2003 by the Federal Highway Administration and AASHTO the author reviews the use of this and other subsequent homeland security related risk assessment guidelines in practice by sharing observations on how threat and vulnerability assessment (TVA) of existing bridges has evolved and where it may be going. The paper focuses on the original objectives of the BRP recommendations, how they align with the latest National Infrastructure Protection Plans for the Transportation Sector, how well their application has worked in practice, whether they assist DOTs and other agencies in obtaining DHS grant funding for security related projects, their application to rail bridges and tunnels, and why they are an essential part in the decision making process for implementing security improvements and countermeasures for bridges and tunnels. This will be discussed in the context of a case study. Since the BRP recommendations were issued best practices for TVAs conducted by some state DOTs have given way to simplified decision tables for risk equations and risk values used with electronic spread sheets that can be used to sort security mitigation costs for critical bridges using cost-benefit factors. The prioritized mitigation projects for existing bridges are then included in the rehabilitation project scope for each bridge when they are contracted out based upon the DOT's state-of-good-repair program. Many states, however, have not yet embraced the BRP recommendations based upon the judgment that funds for repairing deficient bridges are their first priority and they will not deal with security related issues until those needs are addressed. Independent of the availability of funds to repair or secure bridges in a given state or agency, there is a need to prioritize the criticality of the bridge and tunnel inventory because whether a bridge fails due to deterioration, an accident, natural hazards, or intentional attack, the owner should know where the first dollar of funding should be spent, be it for repair of deficiencies or for hazard reduction.
