Work includes developing a comprehensive threat vulnerability assessment that details recommended implementation processes and procedures and estimated physical security upgrade costs for adopted improvements resulting from this study. The comprehensive assessment must address the security risks and requirements of each particular site listed in the agency profile including a comprehensive threat and vulnerability assessment conducted of Everett Transit’s system and assets. As part of the threat and vulnerability assessment, risk assessments must be included in the final comprehensive report. This includes threats connected to criminal activity, terrorism, and civil unrest. This scope of work involves identifying and prioritizing the threats, identifying preventative countermeasures, and identifying the likely costs of each countermeasure to be implemented.
