3.7.10 Electromagnetic Radiation

The enclosure shall be designed and constructed so as to maximize the electromagnetic shielding from external radiation for installed equipment. The walls, floor and roof, excluding any interior partitions, shall provide attenuation of electric fields as specified in Figure 3 and magnetic fields as specified in Figure 4 for equipment located within the enclosure.

The power distribution system shall be installed in accordance with paragraph 5.1of MIL-STD-188-124B (3). All bonding shall be in accordance with the appropriate sub paragraphs of paragraph 5.2 of MIL-STD-188-124124B (3).

3.7.11 Reliability

The enclosure manufacturer shall exercise good engineering practice in the use of derating and redundancy and other reliability oriented techniques to provide a system which is highly reliable under all conditions of deployment, transport and storage. The enclosure assembly shall be designed to operate with a predicted MTBF of at least 33,000 hours in accordance with MIL-HDBK-781A. Figures 3 and 4 are to be utilized for all shelter types except the receive shelter. The receive shelter (G525118) has a magnetic field shielding requirement of 40 dB and a shielding effectiveness for the electrical field of 60 dB between 50k and 100M HZ.

3.7.12 Maintainability

The enclosure manufacturer shall use best commercial engineering practices in design, engineering, and construction of the enclosure assembly to provide a system which is easily maintainable under all expected conditions of deployment, transport, and storage.

Routine Preventative Maintenance (PM) of the enclosure assembly, not including periodic re-tests of shielding and filter effectiveness, shall require less than 12 man-hours per month average that will be performed by the government or designated representative. Government personnel with minimum training should be capable of performing most routine PM procedures.

Adequate access shall be provided to the Government for performing corrective maintenance of ROTHR equipment installed by the customer.

3.8 TRANSPORTABILITY

The configuration shall conform to the dimensional requirements of MIL-STD-1366E.

During transport the Transmit Site Monitor and Receive Site Monitors have approximately 12,500 pounds of installed equipment while the transmit shelter has approximately 11,000 lbs of installed equipment and the receive shelters have approximately 6,500 lbs of installed equipment.

During transport the shelter complex corridors has to be stored safely without damage to the corridor, shelter, or equipment.

3.8.1 Ground Transportability

The completed enclosure shall be capable of withstanding ground transport on a lowboy military vehicle or commercial flatbed semitrailer without permanent mechanical damage or compromise of electromagnetic shielding while fully loaded.

3.8.2 Air Transportability

The enclosure should be capable of withstanding air transport, while fully integrated,by military cargo plane without permanent mechanical damage or co promise of electromagnetic shielding.

3.8.3 Rail Transport

The enclosure shall be capable of withstanding rail transport, while fully integrated, by hydro cushion car, provided that acceleration along each of the three mutually perpendicular axes does not exceed the requirements of paragraph 3.6.11.

3.8.4 Ground Handling

Enclosure support and lift points shall be compatible with the Air Force 463L pallet air cargo handling system and shall be sling system compatible as specified in MIL-STD-209K.

3.8.5. Government Security Access Requirements for Delivery

RAPIDGATE

Commander, Navy Installations Command (CNIC), has established the Navy Commercial Access Control System (NCACS), a standardized process for granting unescorted access privileges to vendors, contractors, suppliers and Attorney Work Product-Privileged Communication service providers not otherwise entitled to the issuance of a Common Access Card (CAC) who seek access to and can provide justification to enter Navy installations and facilities. Visiting vendors may obtain daily passes directly from the individual Navy installations by submitting identification credentials for verification and undergoing a criminal screening/ background check. Alternatively, if the vendor so chooses, it may voluntarily elect to obtain long-term credentials through enrollment, registration, background vetting, screening, issuance of credentials, and electronic validation of credentials at its own cost through one of the designated independent contractor NCACS service providers. Credentials will be issued every five years and access privileges will be reviewed/renewed on an annual basis. The costs incurred to obtain Navy installation access of any kind are not reimbursable, and the price(s) paid for obtaining long-term NCACS credentials will not be approved as a direct cost of this contract. Further information regarding NCACS can be found at Attachment 6 enclosed herein and entitled CNINCNOTE5530 dated 05 July 2012. NCACS is a voluntary program in wich participants who enroll and are subsequently approved for access by the installation, in this case the Forces Surveillance Support Center at Naval Support Activity Hampton Roads, Northwest, Relay Road, Bldg 344, Chesapeake, VA 23322-0726, are not required to obtain a new pass from the base Pass and Identification officefor each visit.

Participation in the NCACS does not relieve the Contractor of its responsibility to submit all Vistit Authorization Letters (VAL) or Visit Requests (VR) via the Joint Personnel Adjudication System (JPAS) for FSSC Security Management Office Code: 45854 for certification of “Need-To-Know”. All requests shall contain the information required by the National Industrial Security Program Operating Manual (NISPOM) and shall not exceed the completion date of the contract or a 12 month period, whichever is shorter.

Upon termination of a Contractor employee with a FSSC acces badge or active VAL on file, the Contractor’s FSO must notifiy the FSSC Security Manager of the terminiation and effective date. Immediately confiscate FSSC issued access badge and Common Access Card (CAC) if issued and return them to the FSSC Security Manager no later than five working days after the effective date of the termination.

Upon expiration of this contract, all documentation shall be returned to FSSC along with the appropriate accountability and control records.

Drawings which are to be used as a basis for fabrication of the shielded enclosure shall be developed by the Contractor and provided to the Government for review and approval at time of delivery for only the first unit of each of the enclosure types identified in paragraph 3.2.1. After delivery of the first unit of each enclosure type, the Contractor is solely responsible for furnishing any updated drawings as necessitated due to changes in the Contractor’s design and/or fabrication of the specified enclosures.

3.9.2 Documentation

The Contractor shall furnish the following documentation to the Government for review and approval at time of delivery for only the first unit of each of the enclosure types identified in paragraph 3.2.1. herein:

After delivery of the first unit of each enclosure type, the Contractor is solely responsible for furnishing any updated documentation in the form of change pages as necessitated due to revisions in the Contractor’s design and/or fabrication of the specified enclosures.
