Countermeasures to Hand-Emplaced Attack Methods on Steel Bridge Members

programmed

From field evaluation reports, the project will inventory bridge members and Hand-Emplaced Improvised Explosive Devices (HEIEDs) modes of attack. The project will list and provide a rating for existing or recommended HEIED retrofit measures of two kinds: Access Control and Blast/Cutting Mitigation. For each member, the project will establish performance requirements for HEIED countermeasures and assess retrofit upgrade options. The project will develop and test selected retrofit upgrade options. Finally, it will develop material and design specifications, a Process Control Manual, and recommendations for effective field implementation of these methods.
