Facility Access Determinations (FAD): The program above allows contractors to work on the NUWC grounds outside of buildings. In order to perform work within existing buildings, a FAD must be submitted. The FAD is a process whereby commanding officers, in their responsibilities under the Internal Security Act of 1950 to protect persons and property under their command against the actions of untrustworthy persons, may request personnel scrutiny investigations and review the results to determine whether to allow the identified person(s) access to facilities under their control. The FAD program also complies with the requirements of Homeland Security Presidential Directive 12 (HSPD-12) to have a background investigation on all individuals who access federal facilities. FADs are required when: Unescorted access to the installation is required for a non-classified contract. A request for a photo ID is submitted. Photo ID’s are only given when the contractor will be on site for a minimum of 3 days per week for a period not less than 90 days. When there is no other background investigation that meets the requirement of HSPD-12 such as a prior NAC, NACI, or TWIC.

The FAD Process consists of the following:

Company submits a complete visit request for the individual. Visit request forms are available from the Security Department or NUWC Website.

The NUWC POC submits a badge card for the individual after verifying that the individual needs access for a minimum of three days per week for a period of at least 90 days.

During the badge card review process, the individual does not have a background investigation that meets the requirements of HSPD-12.

The individual, and the individual’s company, are provided the SF-85 form through the electronic Questionnaire for Investigation Processing (eQip) The eQip is reviewed and the individual is fingerprinted to verify citizenship through a valid birth certificate or US Passport.

OPM conducts the NAC or NACI. Only a determination of Favorable will result in the individual’s unescorted access to NUWCDIVNPT.

If derogatory information occurs after the badge is issued, the contractor will be advised that the issuance of a NUWC badge is the sole prerogative of the commanding officer. If the commanding officer determines, upon review of the facts, that allowing a person to perform certain duties or to access certain areas, would pose an unacceptable risk, that decision is final. No due process procedures are required.

2.16. No Smoking Policy. Smoking is prohibited within and immediately outside of all buildings on installations under the cognizance of NAVFAC, except in designated exterior smoking areas. This applies to existing buildings, buildings under construction and buildings under renovation. Discarding tobacco materials other than into designated tobacco receptacles is considered littering and is subject to fines.

2.17. Working Hours. Regular working hours must consist of an 8 1/2-hour period between 7:00 a.m. and 4:30 p.m., Monday through Friday, excluding Government holidays.

Make application 15 calendar days prior to such work, giving the specific dates, hours, location, type of work to be performed, contract number and project title, to allow arrangements to be made by the Government.

Based on the justification provided, the Government may approve work outside regular hours. During periods of darkness, the work must be lighted in a manner approved by the Government.
