As changes occur and additional information becomes available, correct and change the information contained in previous lists.

2.15. Identification Badges and Installation Access.

Two-step process:

A visit request is required to visit NUWC. The preferred method is JPAS. If the company does not have JPAS, then they must fax or email a visit request with the information required in the visit request form. You may also use AMRDEC SAFE to send your visitor request(https://safe.amrdec.army.mil/SAFE/). Incomplete visits will be rejected. There is a minimum of 3 business days to process.

Naval Station requires one of the following in order to enter the base, along with your NUWC visitor badge:

(a) CAC card

(b) DBIDS card

(c) Retired Military ID

To obtain a DBIDS card a vetting spreadsheet is required and can be acquired from Naval Station to conduct the vetting. You will need a DBIDS card if you do not have the other required IDs. The spreadsheet should be submitted to Visitor Control (group email is nuwc_npt_access_control@navy.mil).

The other option is to use AMRDEC SAFE (https://safe.amrdec.army.mil/SAFE/).

It is certified to protect Privacy Act information. You must use our individual emails:

(keith.p.arnold@navy.mil;Deanna.l.monell.ctr@navy.mil;gina.fleming.ctr@navy.mil;

robin.spradling.ctr@navy.mil).

DBIDS requests are consolidated and submitted each day. Naval Station will not accept DBIDS vetting spreadsheets directly from the companies requiring vetting.

Naval Station requires 5 days to process a vetting spreadsheet. This 5-day period does not include the day of submission nor does it include weekends and holidays. The results except for denials are not returned, if it has been more than five days excluding day of submission and weekends/holidays, and there has been no response, then vetting has been approved.

Also, visitors must stop at B-80 and get their NUWC visitor pass before going to Naval Station Gate 1 to get a DBIDS card. Visitors must not try to enter NUWC with only their visitor pass and no DBIDS (or CAC) as the gate guard will confiscate their NUWC visitor pass and you will be turned around at the gate.

Please keep in mind, DBIDs is only good for 179 days. The company must resubmit their DBIDS vetting spreadsheet every 170 days in order to stay active with their DBIDS card. 170 days is requested so that the vetting can be sent and cleared before the 179 day expiration. If DBIDS isn't sent every 170 days, when the 179 day period expires, they will be denied access to the base and will have to wait 5 business days in order for their vetting to clear again. DBIDS is separate from the visitor request.

If you have any questions on the DBIDS portion, please contact NAVSTA Pass & ID at 401-841-3126.

If you have questions on the visitor request portion, please contact NUWC Visitor Control at 401-832-2152.

Facility Access Determinations (FAD): The NCACS 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.

2.18. Work Outside Regular Hours. If required, work outside regular working hours requires government approval. 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.

2.19. Occupied Existing Building. The Contractor will be working at an existing building and will require a government provided escort during construction. Inside the building the Contractor shall remain with the assigned escort at all times. Make accommodations to limit the disturbance to the building occupants.
