Assessment Process 53 Phase Timeline Components Planning and Preparation (−) Now to Day 0 Identify vulnerable structures and categorize Prioritize and perform maintenance and upgrades on structures, following a prioritized list, if available and based on availability of funds Acquire baseline data and analyze potential impacts to key structures Instrument structures, if possible Develop response plans and procedures for a number of scenarios Perform what-if analyses and update plans and procedures as needed Assign inspection ownership for each structure and highway segment, if possible Identify safe zones and centralized reporting locations Research and review best practices and lessons learned Perform training and drills Coordinate with other agencies Publish communication protocols and procedures Perform regional analysis to develop priority inspection list Assemble list of potential first responders and PDARs for emergency task force Develop guidelines for repairing damaged structures Advance Notification for some emergencies (e.g., hurricanes)

54 Assessing, Coding, and Marking of Highway Structures in Emergency Situations: Research Overview The assessment process was developed based in large part on its ability to satisfy the following attributes: • Practical -- The methodologies must be practical; that is, they must be realistically implementable in diverse organizational structures of a variety of transportation and emergency agencies. • Cost-Effective -- The methodologies must fit within the budgetary constraints of the SHAs.

Assessment Process 55 in Volume 2: Assessment Process Manual. The relevant tasks and efforts are described in detail in Volume 2: Assessment Process Manual and outlined in the following list of key recommendations: • Developing Emergency Operations Plans – Incorporate structural assessments and procedures into the current EOP – Establish the coordination process within the broader missions of the agency • Data Infrastructure and Asset Management – Place quick-response (QR)

56 Assessing, Coding, and Marking of Highway Structures in Emergency Situations: Research Overview 4.4 Assessment Stages The assessment of highway structures during an emergency situation will be accomplished using a four-stage process: Fast Reconnaissance, Preliminary Damage Assessment, Detailed Damage Assessment, and Extended Investigation. The primary scope of this project was to address rapid assessment (i.e., the FR and PDA stages)

Assessment Process 63 The planned coordination and supporting lines of communication should be well-established, understood, and practiced to the point where they are second nature to all involved parties prior to an emergency event. For the purposes of this section, the coordination effort will consider four tiers: 1.
