Any items not included in the Scope of Work that are damaged or altered during construction shall be restored to their pre-construction condition at the contractor’s expense and verified as such by the Government.

Contractor Access and Use of Premises

Ensure that Contractor personnel employed on the Activity become familiar with and obey Activity regulations including safety, fire, traffic and security regulations. Keep within the limits of the work and avenues of ingress and egress. Wear hard hats in designated areas. Do not enter any restricted areas unless required to do so and until cleared for such entry.

Mark Contractor equipment for identification.

Subcontractors and Personnel Contacts

Provide a list of contact personnel of the Contractor and subcontractors including addresses and telephone numbers for use in the event of an emergency. As changes occur and additional information becomes available, correct and change the information contained in previous lists.

Identification Badges and Installation Access

Application for and use of badges will be as directed. Obtain access to the installation by participating in the Navy Commercial Access Control System (NCACS), or by obtaining passes each day from the Base Pass and Identification Office. Costs for obtaining passes through the NCACS are the responsibility of the Contractor. One-day passes, issued through the Base Pass and Identification Office, will be furnished without charge. Furnish a completed EMPLOYEE ELIGIBILITY VERIFICATION (DHS FORM I-9) form for all personnel requesting badges. This form is available at http://www.uscis.gov/portal/site/uscis by searching or selecting Employment Verification (Form I-9). Immediately report instances of lost or stolen badges to the Contracting Officer.

NCACS Program: NCACS is a voluntary program in which Contractor personnel who enroll, and are approved, are subsequently granted access to the installation for a period up to one year, or the length of the contract, whichever is less, and are not required to obtain a new pass from the Base Pass and Identification Office for each visit. The Government performs http://www.uscis.gov/portal/site/uscis background screening and credentialing. Throughout the year the Contractor employee must continue to meet background screening standards. Periodic background screenings are conducted to verify continued NCACS participation and installation access privileges. Under the NCACS program, no commercial vehicle inspection is required, other than for Random Anti-Terrorism Measures (RAM) or in the case of an elevation of Force Protection Conditions (FPCON). Information on costs and requirements to participate and enroll in NCACS is available at http://www.rapidgate.com or by calling 1-877-727-4342.

Contractors should be aware that the costs incurred to obtain NCACS credentials, or costs related to any means of access to a Navy Installation, are not reimbursable. Any time invested, or price(s) paid, for obtaining NCACS credentials will not be compensated in any way or approved as a direct cost of any contract with the Department of the Navy.

Delivery companies submitting NCACS applications must only be granted access if the prime Contractor has included the company on a participant’s spreadsheet provided in advance to the Contracting Officer. This form must be provided to the Government upon request.

One-Day Passes: Participation in the NCACS is not mandatory, and if the Contractor chooses to not participate, the Contractor’s personnel will have to obtain daily passes, be subject to daily, mandatory vehicle inspection, and will have limited access to the installation. The Government will not be responsible for any cost or lost time associated with obtaining daily passes or added vehicle inspections incurred by non-participants in the

NCACS.

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.

http://www.rapidgate.com/

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.

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.

Working Hours

Regular working hours must consist of an 8 1/2 hour period between 7:00 a.m.

Joints for Copper Tubing

Solder conforming to ASTM B32 alloy grade Sb5 or Sn96. Solder and flux shall be lead free (less than 0.2 percent of lead).

An extracted mechanical tee joint may be made in copper tube. Make joint with an appropriate tool by drilling a pilot hole and drawing out the tube surface to form a collar having a minimum height of three times the thickness of the tube wall. To prevent the branch tube from being inserted beyond the depth of the extracted joint, provide dimpled depth stops. Notch the branch tube for proper penetration into fitting to assure a free flow joint. Braze extracted joints using a copper phosphorous classification brazing filler metal.

Soldered joints shall not be permitted.

Press fittings for Copper Pipe and Tube are not allowed on Navy projects.
