Bevilacqua developed, upgrades, maintains and runs the Anti-Terrorism (AT) Planner for the US Army Engineering and Research Center (ERDC). AT Planner was developed to aid the engineer in evaluating force protection issues from terrorist/saboteur attack. Concepts and procedures for protecting personnel and critical assets from civilian or paramilitary groups are evaluated. The AT Planner is a Windows-based application suitable for operation on a notebook computer, and draws on completed and ongoing research related to the protection of fixed facilities from terrorist attack as well as work on field fortifications.
