This Statement of Work (SOW) details security enhancement services for the Naval Foundry and Propeller Center (NFPC) involving door and access control system upgrades across five buildings (B546, B592, B1029, B20, and B712). The project requires removing, replacing, and adding exit monitors, magnet switches, remote panels, and control boards to expand and update the existing Lenel2 OnGaurd security system.

Specific requirements include installing new card readers, electric strikes, panic hardware, and remote panels in various building locations, with work to be performed in designated areas like B20, B1029, B592, B546, and B712. The contractor must ensure all new parts are compatible with the existing security system, install motion sensors and alarms, and test systems to confirm proper functionality. Security requirements mandate personnel complete various government-mandated training, undergo security vetting, and adhere to strict operations security protocols. The work will be performed at the Naval Foundry & Propeller Center in Philadelphia, with delivery and access hours specified as Monday through Friday, 0600 to 1800.
