Follow all current Army Security Regulations concerning strict visitor control and preservation of all Government assets. Immediately report all security concerns to the Contracting Officer.

Work may be affected by the following Force Protection Conditions levels:

FPCON NORMAL

When there is no discernible terrorist activity. Routine security posture.

FPCON ALPHA

When there is a general threat of possible threat activity against personnel and the installation, or both. There will be a limited impact on normal operations.

FPCON BRAVO

When there is an increased or more predictable threat. There will be an impact on normal operations but it will not cause undue hardship to personnel, substantially affect operational capabilities, or cause aggravated relations with local authorities and civilians.

FPCON CHARLIE

When an incident occurs or intelligence is received indicating imminent terrorist action. If this lasts for more than a short period it will probably create hardships for personnel and affect the peacetime activities of units and personnel.

FPCON DELTA

When a terrorist attack has occurred or intelligence indicates likely terrorist action against a specific location. This is normally declared as a localized warning and requires implementation of mandatory security measures. This cannot be sustained for an extended period without causing significant hardships for personnel and affecting the peacetime activities of units and personal.

FPCON NORMAL through FPCON BRAVO will not affect the work. FPCON CHARLIE and FPCON DELTA will affect work. FPCON CHARLIE will subject the Contractor to a higher degree of inspection and may not be able to work on-site for short periods of time as decreed by the District Security Officer.
