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. FPCON DELTA as determined by the District Security Officer will close the site down and the Contractor will not be able to work on the site.

1.8 EVALUATION OF SUBDIVIDED ITEMS

Bid Item Nos. 0002, 0110, 0111, 0404, 0405, 0406, 0512, 0705, 0707, 0708, 0709, 0710, 0713, and 0714 are subdivided into two or more estimated quantities and separately priced. The Government will evaluate each of these items on the basis of total price of the subitems.

1.9 VARIATIONS IN ESTIMATED QUANTITIES - SUBDIVIDED ITEMS

FAR 52.211-18, VARIATION IN ESTIMATED QUANTITIES.

c. If the actual quantity of work performed under Bid Item Nos. 0002, 0110, 0111, 0404, 0405, 0406, 0512, 0705, 0707, 0708, 0709, 0710, 0713, and 0714 exceeds 115 percent or is less than 85 percent of the total estimated quantity of the sub-item under that item and/or if the quantity of the work performed under the second sub-item or any subsequent sub-item under Bid Item Nos. 0002, 0110, 0111, 0404, 0405, 0406, 0512, 0705, 0707, 0708, 0709, 0710, 0713, and 0714 exceeds 115 percent or is less than 85 percent of the estimated quantity of any such sub-item, and if such variation causes an increase or a decrease in the time required for performance of this Contract, the Contract completion time will be adjusted in accordance with FAR 52.211-18, VARIATION IN ESTIMATED QUANTITIES.
